TPElarning tasnifi va xususiyatlarini tushunish masterbatchni qayta ishlashni optimallashtirish va mos keladigan ikkita vintli ekstruderlarni tanlash uchun asosdir..
1.1 Six General Commercial Categories of TPEs
1.1.1 Styrenic Block Copolymers (TPS, TPE-s).
TPS is the most widely used category of TPEs, accounting for a large share of the global TPE market. It is composed of styrenic blocks (such as polystyrene, PS) and elastomeric blocks (such as polybutadiene, PB; polyisoprene, PI; or ethylene-butylene, EB), connected by covalent bonds. The most common types of TPS include SBS (Styrene-Butadiene-Styrene), SIS (Styrene-Isoprene-Styrene), SEBS (Styrene-Ethylene-Butylene-Styrene), and SEPS (Styrene-Ethylene-Propylene-Styrene).
Key properties of TPS include excellent flexibility, elasticity, and processability. SEBS and SEPS, which are hydrogenated versions of SBS and SIS, have improved heat resistance, weather resistance, and aging resistance, making them suitable for outdoor and high-temperature applications. TPS materials are easily colored and modified with masterbatch, va ularni qayta ishlash harorati 150 ℃ dan 220 ℃ gacha, ko'pgina ikkita vintli ekstruderlar bilan mos keladi. TPS ning keng tarqalgan ilovalari avtomobil komponentlarini o'z ichiga oladi, simlar va kabellar, iste'mol tovarlari, va tibbiy asboblar.
1.1.2 Termoplastik poliolefin elastomerlari (TPO, TPE-o).
TPO poliolefinning jismoniy aralashmasidir (polipropilen kabi, PP; yoki polietilen, PE) va elastomer (etilen-propilen-dien monomeri kabi, EPDM). U poliolefinlarning qattiqligini elastomerlarning elastikligi bilan birlashtiradi, va mukammal kimyoviy qarshilikka ega, weather resistance, va past haroratli moslashuvchanlik. TPOlar toksik emas, hidsiz, va qayta ishlanishi mumkin, ularni ekologik tozalikni talab qiluvchi ilovalar uchun ideal qiladi.
TPO ning ishlov berish harorati 160 ℃ dan 230 ℃ gacha, va u turli masterbatchlar bilan yaxshi mos keladi (rangli masterbatch, olovga chidamli masterbatch, va hokazo.). TPOs are widely used in automotive exterior parts (such as bumper covers, fender liners), building materials (such as seals, gaskets), and electrical components. Due to their high polyolefin content, TPO masterbatch processing requires extruders with good mixing capabilities to ensure uniform dispersion of pigments and additives.
1.1.3 Thermoplastic Vulcanizates (TPV, TPE-v).
TPV is a dynamically vulcanized blend of polyolefin (usually PP) va elastomer (usually EPDM). During processing, the elastomer phase is vulcanized into small particles and uniformly dispersed in the polyolefin matrix, resulting in excellent elasticity, compression set resistance, and heat resistance. TPVs have better mechanical properties and dimensional stability than traditional TPEs, and can withstand long-term high-temperature exposure (up to 150℃).
TPVni qayta ishlash bir xil vulkanizatsiya va dispersiyani ta'minlash uchun aniq haroratni nazorat qilish va kuchli kesish kuchini talab qiladi.. Qayta ishlash harorati 170 ℃ dan 240 ℃ gacha, va qayta ishlash jarayonida material yuqori viskoziteye ega, bu ikki vintli ekstruderlarning moment va aşınma qarshiligiga yuqori talablar qo'yadi. TPVlar avtomobil muhrlarida keng qo'llaniladi, shlanglar, gaskets, va yuqori ishlash va chidamlilikni talab qiluvchi sanoat komponentlari.
1.1.4 Termoplastik poliuretanlar (TPU).
TPU qattiq segmentlardan tashkil topgan blok-kopolimerdir (diizosiyanat va zanjir kengaytiruvchisi) va yumshoq segmentlar (poliol). U ajoyib elastiklikka ega, aşınma qarshilik, yog 'qarshiligi, va mexanik kuch, va qattiqligi juda yumshoqdan sozlanishi mumkin (Shor A 30) juda qattiq (Shor D 85) qattiq va yumshoq segmentlarning nisbatini o'zgartirish orqali.
TPU processing is sensitive to temperature and moisture. The processing temperature ranges from 180℃ to 250℃, and the material must be thoroughly dried before processing (moisture content ≤0.05%) to avoid hydrolysis and bubble formation. TPU masterbatch processing requires extruders with precise temperature control and vacuum exhaust capabilities. TPU is widely used in wires and cables, automotive hoses, footwear, medical catheters, and sports equipment.
1.1.5 Thermoplastic Copolyesters (TPC, TPE-E).
TPC is a block copolymer composed of polyester hard segments and polyether or polyester soft segments. It has excellent heat resistance, chemical resistance, and mechanical properties, and can withstand high temperatures up to 150℃ for long periods. TPCs also have good flexibility and elasticity, ularni yuqori samarali ilovalar uchun mos qilish.
TPC ning ishlov berish harorati 220 ℃ dan 280 ℃ gacha, bu boshqa TPE toifalariga qaraganda yuqori. Qayta ishlash jarayonida yuqori viskoziteye ega va yuqori moment va aniq haroratni nazorat qiluvchi ekstruderlarni talab qiladi.. TPC masterbatch bilan ishlov berish, shuningdek, materialning mexanik xususiyatlariga ta'sir qilmaslik uchun pigmentlar va qo'shimchalarning tarqalishiga alohida e'tibor talab qiladi.. TPClar avtomobil komponentlarida keng qo'llaniladi (havo olish shlanglari kabi, uzatish muhrlari), aerokosmik qismlar, va sanoat mashinalari.
1.1.6 Termoplastik poliamidlar (TPA, TPE-A).
TPA poliamid qattiq segmentlari va polieter yumshoq segmentlaridan tashkil topgan blokli kopolimerdir. U yuqori quvvatni birlashtiradi, aşınma qarshilik, va poliamidlarning poliefirlarning moslashuvchanligi va elastikligi bilan kimyoviy qarshilik. TPA mukammal zarba qarshiligiga va past harorat ko'rsatkichlariga ega, va og'ir muhitda foydalanish mumkin.
TPA ning ishlov berish harorati 230 ℃ dan 290 ℃ gacha, va u yuqori suv singdirish xususiyatiga ega, qayta ishlashdan oldin yaxshilab quritishni talab qiladi. TPA masterbatchni qayta ishlash yuqori aşınma qarshilikka ega ekstruderlarni talab qiladi (poliamidning yuqori qattiqligi tufayli) va materialning buzilishini oldini olish uchun haroratni aniq nazorat qilish. TPA avtomobil komponentlarida keng qo'llaniladi (viteslar kabi, podshipniklar), elektr konnektorlari, va sanoat shlanglari.
1.2 Masterbatch qayta ishlashga ta'sir qiluvchi TPE ning asosiy xususiyatlari
TPElar ularni an'anaviy plastmassalardan ajratib turadigan o'ziga xos xususiyatlarga ega, va bu xususiyatlar to'g'ridan-to'g'ri masterbatchni shakllantirishga va ekstruziya uskunalarini tanlashga ta'sir qiladi. Masterbatchni qayta ishlashda e'tiborga olinadigan asosiy xususiyatlar quyidagilardir:
1.2.1 Elastiklik va moslashuvchanlik.
TPElar yuqori elastiklik va moslashuvchanlikka ega, Bu materialning elastik ishlashini pasaytirmaslik uchun masterbatch TPE matritsasiga mos kelishi kerakligini anglatadi.. Masterbatch tashuvchisi TPE bilan yaxshi mos kelishi kerak, va dispersant stress kontsentratsiyasini keltirib chiqaradigan va moslashuvchanlikni kamaytiradigan aglomeratlar hosil qilmasdan pigmentlarning bir xil tarqalishini ta'minlashi kerak..
1.2.2 Issiqlikka chidamlilik.
Turli TPE toifalari har xil issiqlikka chidamliligiga ega (ishlov berish harorati 150 ℃ dan 290 ℃ gacha). Masterbatch pigmentlari va qo'shimchalari parchalanishning oldini olish uchun TPE ishlov berish haroratiga mos keladigan issiqlikka chidamli bo'lishi kerak, rangsizlanish, yoki ekstruziya paytida ishlashning pasayishi. Masalan, TPC and TPA require high-temperature resistant pigments and heat stabilizers.
1.2.3 Viscosity and Processability.
TPEs have varying viscosities during processing (TPV and TPC have higher viscosity, while TPS has lower viscosity). This affects the shear force and conveying requirements of the twin-screw extruder. High-viscosity TPEs require extruders with high torque and strong mixing capabilities, while low-viscosity TPEs require precise control of extrusion speed to avoid material overflow.
1.2.4 Moisture Absorption.
Some TPEs (such as TPU, TPA) have high water absorption, which can cause bubbles, hydrolysis, and other defects in the masterbatch. The raw materials (TPE, pigments, qo'shimchalar) must be thoroughly dried before processing, and the extruder should be equipped with a vacuum exhaust device to remove moisture and volatile substances.
1.2.5 Compatibility with Additives.
TPEs often require functional additives (such as antioxidants, UV stabilizers, lubricants) to improve their performance. The masterbatch should be formulated to ensure that the additives are compatible with both the pigments and the TPE matrix, avoiding chemical reactions that could affect product quality.
2. Masterbatch for TPEs: Composition, Formulation and Processing Requirements
Masterbatch for TPEs is a concentrated mixture of pigments/dyes, carriers, and additives, designed to color TPEs and impart additional functions (such as flame retardancy, antistatik, antibacterial) while maintaining the material’s inherent elastic and processing properties. The formulation and processing of TPE masterbatch are more demanding than those for traditional plastics, due to the unique properties of TPEs. This section details the composition, formulation principles, and processing requirements of TPE masterbatch.
2.1 Core Composition of TPE Masterbatch
Like traditional masterbatch, TPE masterbatch consists of three basic components: pigments/dyes, carriers, and additives. The selection and proportion of each component are tailored to the type of TPE and its application requirements.
2.1.1 Pigments/Dyes.
Pigments/dyes are the core components that impart color to TPEs, accounting for 10%-70% of the masterbatch composition (depending on the color intensity and TPE type). The key requirements for pigments/dyes in TPE masterbatch are:
- – Issiqlikka chidamlilik: Must withstand the processing temperature of the target TPE (150℃-290℃) without decomposition or discoloration. For high-temperature TPEs (TPC, TPA), high-temperature resistant organic pigments or inorganic pigments are preferred.
- – Compatibility: Must be compatible with the TPE matrix to avoid migration, blooming, yoki elastiklikning pasayishi. TPE ga o'xshash polariteli pigmentlar ko'proq mos keladi (masalan, TPU uchun qutbli pigmentlar, TPS uchun qutbsiz pigmentlar).
- – Tarqalish qobiliyati: Bir xil rang berishni ta'minlash va rangli dog'lar paydo bo'lishining oldini olish uchun TPE matritsasida osongina tarqalishi kerak, chiziqlar, yoki mexanik xususiyatlarning pasayishi. Nozik zarrachali pigmentlar (20-40 to'r) past aglomeratsiyaga ega bo'lganlarga afzallik beriladi.
- – Atrof-muhitga do'stlik: Global atrof-muhitni muhofaza qilish standartlariga javob berishi kerak (REACH kabi, RoHS) toksik yoki zararli moddalardan qochish uchun (og'ir metallar kabi) inson salomatligi va atrof-muhitga ta'sir qilishi mumkin.
TPE masterbatchda ishlatiladigan umumiy pigmentlar kiradi: noorganik pigmentlar (oq uchun titan dioksidi, qora uchun uglerod qora, qizil/sariq uchun temir oksidi), va yuqori haroratga chidamli organik pigmentlar (ftalosiyanin ko'k / yashil, kinokridon qizil).
2.1.2 Tashuvchilar.
Tashuvchilar masterbatchning matritsasi hisoblanadi, accounting for 20%-80% tarkibi haqida, and play a key role in dispersing pigments and adhering to the TPE matrix. The carrier must have excellent compatibility with both the pigments and the target TPE, as poor compatibility can lead to pigment migration, uneven coloring, and reduced TPE performance. The selection of the carrier is based on the type of TPE:
- – For TPS (SBS, SEBS): Use TPS or PP as the carrier, which has good compatibility and processing fluidity.
- – For TPO/TPE-o: Use PP or PE as the carrier, matching the polyolefin component of the TPO.
- – For TPV/TPE-v: Use PP as the carrier, which is compatible with the PP matrix of the TPV.
- – For TPU: Use TPU as the carrier, ensuring compatibility with the TPU matrix and avoiding hydrolysis.
- – For TPC/TPE-E and TPA/TPE-A: Use TPC or TPA as the carrier, respectively, yuqori haroratli ishlov berish talablariga va muvofiqlikka mos kelish.
Tashuvchi ham yaxshi ishlov berish suyuqligiga ega bo'lishi kerak, erish nuqtasi va maqsadli TPEga mos keladigan yoki undan biroz pastroq ishlov berish harorati bilan, bir xil aralashtirishni ta'minlash va TPE degradatsiyasini oldini olish.
2.1.3 Qo'shimchalar.
Qo'shimchalar - bu ishlov berish samaradorligini oshirish uchun qo'shiladigan yordamchi komponentlar, tarqalish qobiliyati, va TPE masterbatchning funktsional ishlashi, accounting for 1%-10% tarkibi haqida. Qo'shimchalarning turi va dozasi TPE turi va qo'llanilishi talablari bilan belgilanadi:
- – Dispersantlar: TPE masterbatch uchun eng muhim qo'shimcha, pigment sirt tarangligini kamaytirish uchun ishlatiladi, aglomeratsiyani oldini oladi, va TPE matritsasida bir xil dispersiyani ta'minlash. Umumiy dispersantlarga polietilen mumi kiradi, polipropilen mumi, stearin kislotasi, va malein angidrid payvandlangan mumlar. Yuqori viskoziteli TPElar uchun (TPV, TPC), kuchli uyg'unlikka ega yuqori samarali dispersantlarga afzallik beriladi.
- – Muvofiqlashtiruvchilar: Pigmentlar va TPElar o'rtasidagi muvofiqlikni yaxshilash uchun ishlatiladi, va masterbatch va TPE matritsasi o'rtasida. Masalan, maleik angidrid payvandlangan PP TPO masterbatch uchun moslashtiruvchi sifatida ishlatiladi, va poliuretan mumi TPU masterbatch uchun ishlatiladi.
- – Issiqlik stabilizatorlari: Yuqori haroratli ishlov berish jarayonida pigment parchalanishini va TPE degradatsiyasini oldini olish uchun ishlatiladi. Umumiy issiqlik stabilizatorlariga organik qalay stabilizatorlari kiradi (TPU uchun), fenol antioksidantlarini to'sqinlik qiladi (TPS uchun, TPO), va fosfit antioksidantlari (TPC uchun, TPA).
- – UV stabilizatorlari va antioksidantlar: Rangli TPE mahsulotlarining ob-havoga chidamliligi va qarish qarshiligini yaxshilash uchun ishlatiladi, quyosh nuri va kislorod ta'sirida ranglarning o'zgarishi va ishlashning yomonlashishini oldini olish. Tashqi ilovalar uchun (avtomobil tashqi qismlari kabi), UV absorbers and hindered amine light stabilizers (HALS) are added.
- – Lubricants: Used to reduce friction between materials and extrusion equipment (screw, barrel, die head), improve processing fluidity, and avoid material sticking to equipment. Common lubricants include stearic acid, calcium stearate, and silicone oil. For TPU and TPA, lubricants with low migration are preferred to avoid affecting product performance.
- – Functional Additives: Added to impart special functions to TPEs, such as flame retardants (for wires and cables), antistatic agents (for electrical components), and antibacterial agents (for medical devices and consumer goods).
2.2 Formulation Principles of TPE Masterbatch
The formulation of TPE masterbatch must balance coloring effect, processing performance, and TPE inherent properties. The key principles are as follows:
2.2.1 Compatibility First.
The carrier, pigments, va qo'shimchalar materialning elastikligini pasaytirmaslik uchun maqsadli TPE bilan mos kelishi kerak, moslashuvchanlik, and mechanical properties. Masalan, qutbli TPU uchun qutbsiz tashuvchidan foydalanish yomon muvofiqlik va pigment migratsiyasiga olib keladi.
2.2.2 Issiqlik qarshiligiga mos kelish.
Pigmentlar va qo'shimchalar TPE ishlov berish haroratiga mos keladigan issiqlikka chidamli bo'lishi kerak. Masalan, TPC masterbatch yuqori haroratga chidamli pigmentlardan foydalanadi (issiqlikka chidamlilik ≥280 ℃) qayta ishlash jarayonida parchalanishni oldini olish uchun.
2.2.3 Tarqalish qobiliyatini optimallashtirish.
Pigment tarkibi va dispersant dozasi bir xil dispersiyani ta'minlash uchun o'rnatiladi. Yuqori konsentratsiyali masterbatch (pigment tarkibi 50%-70%) ko'proq dispersantlar va yaxshiroq aralashtirish qobiliyatini talab qiladi, past konsentratsiyali masterbatch esa (10%-30%) muvofiqligiga e’tibor qaratadi.
2.2.4 TPE xususiyatlariga ta'sirni minimallashtirish.
Masterbatch TPE ning elastikligiga sezilarli ta'sir ko'rsatmasligi kerak, siqish to'plami, or abrasion resistance. Masalan, excessive dispersants or lubricants may reduce the TPE’s mechanical strength.
2.2.5 Environmental Protection Compliance.
The formulation must meet global environmental protection standards, avoiding toxic or harmful substances (og'ir metallar kabi, phthalates) that could restrict market access.
2.3 Processing Requirements of TPE Masterbatch
TPE masterbatch processing is mainly carried out using twin-screw extrusion technology, which requires strict control of raw material pretreatment, premixing, extrusion parameters, and post-processing to ensure product quality. The key processing requirements are as follows:
2.3.1 Raw Material Pretreatment.
TPEs (especially TPU, TPA) have high water absorption, so all raw materials (TPE carrier, pigments, qo'shimchalar) must be thoroughly dried before processing. The drying temperature and time are determined by the material type: TPU/TPA is dried at 100-120℃ for 6-8 soat, TPS/TPO is dried at 80-100℃ for 3-5 soat, va pigmentlar uchun 60-80 ℃ da quritiladi 2-4 soat. Quritilgan xom ashyoning namligini quyida nazorat qilish kerak 0.1% (0.05% TPU/TPA uchun).
Bunga qo'chimcha, katta zarrachalar yoki aglomeratlar bo'lgan pigmentlarni maydalash va elakdan o'tkazish kerak (20-40 to'r) dispersiyani yaxshilash uchun, va aralashmalar (metall zarralari, chang) ekstruziya uskunasining aşınmasını va masterbatchdagi nuqsonlarni oldini olish uchun olib tashlanishi kerak.
2.3.2 Oldindan aralashtirish.
Quritilgan xom ashyo (pigments, tashuvchi, qo'shimchalar) formulalar nisbati bo'yicha yuqori tezlikda ishlaydigan aralashtirgichda bir hil dastlabki aralashmani hosil qilish uchun aralashtiriladi. Oldindan aralashtirish parametrlari TPE turiga qarab o'rnatiladi: aralashtirish tezligi 800-1200 rpm, aralashtirish vaqti 5-10 daqiqa, aralashtirish harorati 40-60 ℃. Yuqori konsentratsiyali masterbatch yoki yuqori viskoziteli TPE tashuvchilar uchun, oldindan aralashtirish vaqti uzaytiriladi, va pigmentlarni qoplash uchun birinchi navbatda dispersantlar qo'shiladi, tarqalish qobiliyatini yaxshilash.
2.3.3 Ekstruziya parametrlarini boshqarish.
Twin-screw extrusion is the core step of TPE masterbatch processing, and the key parameters (temperature, vida tezligi, extrusion pressure, feeding speed) must be precisely controlled to match the TPE type:
- – Temperature Control: The barrel is divided into 4-6 temperature control sections (feeding section, melting section, mixing section, homogenizing section, die head section). The temperature of each section is adjusted according to the TPE processing temperature. Masalan, TPS masterbatch: feeding section 100-120℃, melting section 160-180℃, mixing section 170-190℃, homogenizing section 160-180℃, die head section 150-170℃; TPC masterbatch: feeding section 150-170℃, melting section 230-250℃, mixing section 240-260℃, homogenizing section 230-250℃, die head section 220-240℃. The temperature control precision should reach ±1℃ to avoid TPE degradation and pigment decomposition.
- – Screw Speed: The screw speed ranges from 200-800 rpm, adjusted based on TPE viscosity. High-viscosity TPEs (TPV, TPC) require higher screw speed (500-800 rpm) to generate sufficient shear force for pigment dispersion; low-viscosity TPEs (TPS) use moderate speed (300-500 rpm) to avoid material overflow.
- – Extrusion Pressure: The pressure ranges from 5-12MPa, kept stable (fluctuation ≤±0.5MPa) to ensure uniform mixing and shaping. High-viscosity TPEs require higher pressure, while low-viscosity TPEs use moderate pressure.
- – Feeding Speed: Adjusted to match the screw speed and extrusion speed, ensuring stable and uniform feeding. Yuqori viskoziteli TPElar uchun, a forced feeding device is used to avoid material accumulation.
2.3.4 Post-Processing.
After extrusion, the strip-shaped masterbatch is cooled (water tank cooling, 20-30℃), granulated (zarrachalar hajmi 2-5 mm), ekranlangan (sifatsiz zarralarni olib tashlash uchun), va qadoqlangan (muhrlangan va namlikka chidamli qadoqlash). Namlikka sezgir TPE masterbatch uchun (TPU, TPA), tayyor mahsulot namlikning emilishini oldini olish uchun qadoqlashdan oldin yana quritiladi.

The test results show that the TPC masterbatch produced has a mixing uniformity of ≥98%, no color spots or streaks, and the pigment dispersion effect is significantly better than the customer’s original equipment. The masterbatch maintains stable performance after high-temperature processing at 260℃, with no discoloration or degradation, fully meeting the requirements of new energy vehicle automotive hoses. The production capacity reaches 1500kg/h, which is 40% higher than the original equipment, while the energy consumption is reduced by 22%, significantly reducing the customer’s production costs. The wear of screws and barrels is greatly reduced, and the maintenance cycle is extended from 1 month to 6 oylar, reducing maintenance costs by more than 50%. The customer’s TPC hoses made of this masterbatch have passed the automotive industry quality certification, with excellent high-temperature resistance and mechanical strength, and have been successfully supplied to major new energy vehicle manufacturers. The customer highly recognized Zhuoyue’s extrusion solution, and subsequently signed a long-term cooperation agreement, purchasing 5 more sets of HTS SUPER series extruders to expand production scale.
