Masterbatch-ferwurking mei Twin-Screw Extruders Fokus op Thermoplastic Elastomer (TPE) Applikaasjes

Ynhâldsopjefte

Thermoplastyske elastomers (TPE), soms oantsjutten as Thermoplastic Rubbers (TPR), binne in klasse fan kopolymeren as fysike mingden fan polymeren - typysk in plestik en in rubber - dy't de eigenskippen fan thermoplasten en elastomeren kombinearje. Dizze unike kombinaasje lit TPE's wurde ferwurke as thermoplastyk (fia extrusion, ynjeksje moulding, blow moulding, ensfh.) wylst it behâld fan de elastisiteit en fleksibiliteit fan rubbers. Oars as tradisjonele vulkanisearre rubbers, TPE's kinne meardere kearen wurde smelt en opnij ferwurke sûnder signifikant ferlies fan prestaasjes, wêrtroch't se miljeufreonliker en rendabeler meitsje. As de fraach nei lichtgewicht, fleksibel, en recyclebere materialen groeit oer yndustry lykas automotive, elektryske, konstruksje, en konsuminteguod, TPE's binne hieltyd populêrder wurden, driuwt de ûntwikkeling fan spesjalisearre masterbatch en extrusion technologyen ôfstimd op harren unike ferwurkjen easken.

Masterbatch, as in wichtich materiaal foar kleurjen en funksjonele modifikaasje fan TPE's, spilet in krúsjale rol by it ferbetterjen fan de prestaasjes en it útwreidzjen fan it tapassingsgebiet fan TPE-produkten. De ferwurking fan TPE masterbatch fereasket sekuere kontrôle fan it mingen, fersprieden, en temperatuer parameters, as TPEs hawwe spesifike viscosity, waarmte ferset, en elastisiteitseigenskippen dy't ferskille fan tradisjonele plestik. Twin-screw extruders, mei harren superieure mingen en dispergering mooglikheden, presys temperatuer kontrôle, en oanpassing oan ferskate materialen, binne wurden de kearn ferwurkjen apparatuer foar TPE masterbatch. Zhuoyue, in profesjonele fabrikant fan twin-screw extruders, biedt in folslein oanbod fan avansearre extrusion oplossings spesifyk ûntwurpen foar TPE compounding en masterbatch ferwurkjen, covering TPE / SBS / TPU / TPR / TPV en oare grutte TPE kategoryen, om te foldwaan oan de ferskate behoeften fan fabrikanten yn ferskate yndustry.

1. Oersjoch fan Thermoplastic Elastomers (TPE): Kategoryen, Eigenskippen en kaai skaaimerken

TPE's binne in ferskaat famylje fan materialen, yndield yn seis algemiene kommersjele kategoryen basearre op har gemyske gearstalling en struktuer. Elke kategory hat unike eigenskippen, ferwurkjen skaaimerken, en applikaasje fjilden, dy't direkt bepale de easken foar masterbatch formulearring en extrusion apparatuer. De klassifikaasje en eigenskippen fan TPE's begripe is de basis foar it optimalisearjen fan masterbatchferwurking en it selektearjen fan geskikte twin-screw-ekstruders.

1.1 Seis Algemiene kommersjele kategoryen fan TPE's

1.1.1 Styrenic Block Copolymers (TPS, TPE-s).

TPS is de meast brûkte kategory fan TPE's, goed foar in grut oandiel fan 'e wrâldwide TPE-merk. It is gearstald út styreenyske blokken (lykas polystyrene, PS) en elastomere blokken (lykas polybutadiene, PB; polyisoprene, PI; of ethylene-butyleen, EB), ferbûn troch kovalente obligaasjes. De meast foarkommende soarten TPS omfetsje SBS (Styrenes-Butadienes-Styrenes), SIS (Styreen-Isoprene-Styreen), SEBS (Styreen-ethylene-butyleen-styrene), en SEPS (Styreen-ethylene-propylene-styrene).

Key eigenskippen fan TPS omfetsje poerbêste fleksibiliteit, elastisiteit, en ferwurkberens. SEBS en SEPS, dat binne hydrogenated ferzjes fan SBS en SIS, hawwe ferbettere waarmte ferset, waar ferset, en ferâldering ferset, wêrtroch se geskikt binne foar bûten- en hege temperatuerapplikaasjes.

Algemiene tapassingen fan TPS omfetsje autokomponinten, draden en kabels, konsumint guod, en medyske apparaten.

1.1.2 Thermoplastyske polyolefinelastomers (TPO, TPE-o).

TPO is in fysike mingsel fan polyolefin (lykas polypropylene, PP; of polyetyleen, PE) en elastomeer (lykas ethylene-propylene-dieen monomer, EPDM). It kombinearret de rigidity fan polyolefins mei de elasticiteit fan elastomers, en hat poerbêste gemyske ferset, waar ferset, en lege temperatuer fleksibiliteit. TPO's binne net-giftig, reukleas, en recycleber, wêrtroch't se ideaal binne foar applikaasjes dy't miljeufreonlikens fereaskje.

De ferwurkingstemperatuer fan TPO farieart fan 160 ℃ oant 230 ℃, en it hat goede komptabiliteit mei ferskate masterbatches (kleur masterbatch, flammefertragende masterbatch, ensfh.). TPO's wurde in soad brûkt yn auto-eksterieurdielen (lykas bumper covers, fender liners), boumaterialen (lykas seehûnen, pakkingen), en elektryske komponinten. Troch har hege polyolefinynhâld, TPO masterbatch-ferwurking fereasket extruders mei goede mingmooglikheden om unifoarme fersprieding fan pigmen en tafoegings te garandearjen.

1.1.3 Thermoplastyske Vulcanizates (btw, TPE v).

TPV is in dynamysk vulkanisearre mingsel fan polyolefin (meastal PP) en elastomeer (meastal EPDM). Tidens it ferwurkjen, de elastomere faze wurdt vulcanized yn lytse dieltsjes en unifoarm ferspraat yn de polyolefin matrix, resultearret yn poerbêste elastisiteit, kompresje set ferset, en waarmte ferset.

TPV-ferwurking fereasket krekte temperatuerkontrôle en sterke skuorkrêft om unifoarme fulkanisaasje en dispersje te garandearjen. De ferwurkingstemperatuer farieart fan 170 ℃ oant 240 ℃, en it materiaal hat hege viskositeit by it ferwurkjen, dy't hege easken stelt oan it koppel en slijtweerstand fan twin-screw extruders. TPV's wurde in protte brûkt yn auto-segels, hoses, pakkingen, en yndustriële komponinten dy't hege prestaasjes en duorsumens nedich binne.

1.1.4 Thermoplastyske polyurethanen (TPU).

TPU is in blok copolymer gearstald út hurde segminten (diisocyanat en kettingferlenger) en sêfte segminten (polyol). It hat poerbêste elastisiteit, abrasion ferset, oalje ferset, en meganyske sterkte, en kin oanpast wurde yn hurdens fan hiel sêft (Shore A 30) oan hiel hurd (Shore D 85) troch it feroarjen fan de ferhâlding fan hurde en sêfte segminten.

TPU-ferwurking is gefoelich foar temperatuer en focht. De ferwurkingstemperatuer farieart fan 180 ℃ oant 250 ℃, en it materiaal moat goed droech wurde foardat it ferwurke wurdt (vochtgehalte ≤0.05%) om hydrolyse en bubbelfoarming te foarkommen. TPU masterbatch ferwurking fereasket extruders mei sekuere temperatuer kontrôle en fakuüm exhaust mooglikheden. TPU wurdt in soad brûkt yn triedden en kabels, auto-slangen, skuon, medyske katheters, en sportapparatuer.

1.1.5 Thermoplastyske copolyesters (TPC, TPE-E).

TPC is in blok copolymer gearstald út polyester hurde segminten en polyether of polyester sêfte segminten. It hat poerbêst waarmte ferset, gemyske ferset, en meganyske eigenskippen, en kin fernear hege temperatueren oant 150 ℃ foar lange perioaden. TPC's hawwe ek goede fleksibiliteit en elastisiteit, wêrtroch't se geskikt foar hege-optreden applikaasjes.

De ferwurkingstemperatuer fan TPC farieart fan 220 ℃ oant 280 ℃, dat is heger as oare TPE kategoryen. It hat hege viskositeit by it ferwurkjen en fereasket extruders mei hege koppel en krekte temperatuerkontrôle. TPC-masterbatch-ferwurking fereasket ek spesjaal omtinken foar de fersprieding fan pigmen en tafoegings om foar te kommen dat de meganyske eigenskippen fan it materiaal beynfloedzje. TPC's wurde in protte brûkt yn auto-ûnderdielen (lykas lucht intake slangen, oerdracht sealen), aerospace dielen, en yndustriële masines.

TPA wurdt in protte brûkt yn auto-ûnderdielen (lykas gears, lagers), elektryske Anschlüsse, en yndustriële slangen.

1.2 Wichtige eigenskippen fan TPE's dy't ynfloed hawwe op Masterbatch-ferwurking

TPE's hawwe unike eigenskippen dy't har ûnderskiede fan tradisjonele plestik, en dizze eigenskippen direkt ynfloed op de formulearring fan masterbatch en de seleksje fan extrusion apparatuer. De wichtichste eigenskippen om te beskôgje yn masterbatch-ferwurking binne as folget:

1.2.1 Elastisiteit en fleksibiliteit.

TPE's hawwe hege elastisiteit en fleksibiliteit, wat betsjut dat de masterbatch kompatibel wêze moat mei de TPE-matrix om foar te kommen dat de elastyske prestaasjes fan it materiaal ferminderje. De drager fan 'e masterbatch moat in goede kompatibiliteit hawwe mei de TPE, en it dispergeermiddel moat soargje foar unifoarme fersprieding fan pigmen sûnder agglomeraten te foarmjen dy't stresskonsintraasje kinne feroarsaakje en fleksibiliteit ferminderje.

1.2.2 Heat Resistance.

Ferskillende TPE kategoryen hawwe ferskillende waarmte ferset (ferwurkjen temperatuer farieart fan 150 ℃ oant 290 ℃). Masterbatch-pigmen en tafoegings moatte waarmtebestriding hawwe dy't oerienkomme mei de TPE-ferwurkingstemperatuer om ûntbining te foarkommen, ferkleuring, of prestaasjesdegradaasje by extrusion. Bygelyks, TPC en TPA fereaskje hege temperatuer resistinte pigminten en waarmte stabilisatoren.

1.2.3 Viskositeit en ferwurkberens.

TPE's hawwe ferskate viskositeiten tidens ferwurking (TPV en TPC hawwe hegere viskositeit, wylst TPS hat legere viscosity). Dit beynfloedet de skuorkrêft en ferfiereasken fan 'e twin-screw-extruder. TPE's mei hege viskositeit fereaskje extruders mei hege koppel en sterke mingmooglikheden, wylst TPE's mei lege viskositeit easkje krekte kontrôle fan extrusion snelheid om materiaal oerstreaming te foarkommen.

1.2.4 Moisture Absorption.

Guon TPEs (lykas TPU, TPA) hawwe hege wetterabsorption, dy't bubbels feroarsaakje kinne, hydrolyse, en oare defekten yn 'e masterbatch. De grûnstoffen (TPE, pigminten, tafoegings) moat goed droech wurde foardat ferwurking, en de extruder moat wêze foarsjoen fan in fakuüm exhaust apparaat te ferwiderje focht en flechtich stoffen.

1.2.5 Kompatibiliteit mei tafoegings.

TPE's hawwe faak funksjonele tafoegings nedich (lykas antioxidants, UV stabilisatoren, lubricants) om har prestaasjes te ferbetterjen. De masterbatch moat wurde formulearre om te soargjen dat de tafoegings kompatibel binne mei sawol de pigmen as de TPE-matrix, it foarkommen fan gemyske reaksjes dy't de produktkwaliteit kinne beynfloedzje.

2. Masterbatch foar TPE's: Gearstalling, Formulering en ferwurkjen easken

Masterbatch foar TPE's is in konsintrearre mingsel fan pigminten / kleurstoffen, ferfierders, en tafoegings, ûntworpen om TPE's te kleurjen en ekstra funksjes te jaan (lykas flammefertraging, antistatyske, antibakteriële) wylst behâld fan it materiaal syn ynherinte elastyske en ferwurkjen eigenskippen. De formulearring en ferwurking fan TPE masterbatch binne mear easken dan dy foar tradisjonele plestik, fanwege de unike eigenskippen fan TPE's. Dizze seksje beskriuwt de komposysje, formulearringsprinsipes, en ferwurkjen easken fan TPE masterbatch.

2.1 Kearn Gearstalling fan TPE Masterbatch

Lykas tradisjonele masterbatch, TPE masterbatch bestiet út trije basiskomponinten: pigmenten / kleurstoffen, ferfierders, en tafoegings. De seleksje en it oanpart fan elke komponint wurde ôfstimd op it type TPE en har tapassingseasken.

2.1.1 Pigmenten / kleurstoffen.

Pigminten / kleurstoffen binne de kearnkomponinten dy't kleur jaan oan TPE's, accounting foar 10%-70% fan 'e masterbatch-komposysje (ôfhinklik fan de kleurintensiteit en TPE-type). De kaai easken foar pigminten / kleurstoffen yn TPE masterbatch binne:

  • – Heat Resistance: Moat wjerstean de ferwurking temperatuer fan it doel TPE (150℃-290 ℃) sûnder ûntbining of ferkleuring. Foar hege temperatuer TPEs (TPC, TPA), hege temperatuer-resistinte organyske pigminten as anorganyske pigminten hawwe de foarkar.
  • – Kompatibiliteit: Moat kompatibel wêze mei de TPE-matrix om migraasje te foarkommen, bloeiende, of fermindere elastisiteit. Pigminten mei ferlykbere polariteit as de TPE binne mear kompatibel (bgl., polêre pigminten foar TPU, net-polêre pigminten foar TPS).
  • – Dispersibility: Moat maklik wurde ferspraat yn 'e TPE-matrix om unifoarme kleur te garandearjen en kleurflekken te foarkommen, strepen, of fermindere meganyske eigenskippen. Fine-particle pigminten (20-40 mesh) mei lege agglomeraasje hawwe de foarkar.
  • – Miljeufreonlikens: Moat foldogge oan wrâldwide noarmen foar miljeubeskerming (lykas REACH, RoHS) om giftige of skealike stoffen te foarkommen (lykas swiere metalen) dat kin ynfloed op minsklike sûnens en it miljeu.

Algemiene pigminten brûkt yn TPE masterbatch omfetsje: anorganyske pigmenten (titanium dioxide foar wyt, koalstof swart foar swart, izer okside foar read / giel), en hege temperatuer resistinte organyske pigminten (phthalocyanine blau / grien, quinacridon read).

2.1.2 Ferfierders.

Dragers binne de matrix fan 'e masterbatch, accounting foar 20%-80% fan de komposysje, en spylje in wichtige rol yn it fersprieden fan pigminten en adhering oan de TPE matrix. De drager moat poerbêste kompatibiliteit hawwe mei sawol de pigmen as de doel-TPE, as minne kompatibiliteit kin liede ta pigmentmigraasje, oneffen kleuring, en fermindere TPE prestaasjes. De seleksje fan 'e drager is basearre op it type TPE:

  • – Foar TPS (SBS, SEBS): Brûk TPS of PP as drager, dat hat goede komptabiliteit en ferwurkjen fluidity.
  • – Foar TPO/TPE-o: Brûk PP of PE as drager, oerienkomt mei de polyolefinkomponint fan 'e TPO.
  • – Foar TPV/TPE-v: Brûk PP as drager, dy't kompatibel is mei de PP-matrix fan 'e TPV.
  • – Foar TPU: Brûk TPU as drager, garandearjen fan kompatibiliteit mei de TPU-matrix en it foarkommen fan hydrolyse.
  • – Foar TPC/TPE-E en TPA/TPE-A: Brûk TPC of TPA as drager, respektivelik, om te passen oan de easken foar ferwurkjen fan hege temperatueren en kompatibiliteit.

De drager moat ek in goede ferwurkingsfluiditeit hawwe, mei in smeltpunt en ferwurkjen temperatuer konsekwint mei of wat leger as de doel TPE, om unifoarm mingen te garandearjen en TPE-degradaasje te foarkommen.

2.1.3 Additieven.

Additiven binne auxiliary komponinten tafoege om de ferwurkingsprestaasjes te ferbetterjen, dispersibility, en funksjonele prestaasjes fan TPE masterbatch, accounting foar 1%-10% fan de komposysje. It type en dosaasje fan tafoegings wurde bepaald troch it TPE-type en tapassingseasken:

  • – Dispersanten: De wichtichste tafoeging foar TPE masterbatch, brûkt om pigment oerflak spanning te ferminderjen, agglomeraasje foarkomme, en soargje foar unifoarme fersprieding yn 'e TPE-matrix. Algemiene dispersanten binne polyetyleenwax, polypropylene wax, stearinezuur, en maleïnezuuranhydride ente waaksen. Foar hege viskositeit TPE's (btw, TPC), dispersanten mei hege effisjinsje mei sterke kompatibiliteit hawwe de foarkar.
  • – Kompatibilizers: Wurdt brûkt om kompatibiliteit te ferbetterjen tusken pigminten en TPE's, en tusken masterbatch en TPE matrix. Bygelyks, maleïnezuuranhydride ent PP wurdt brûkt as kompatibilisator foar TPO masterbatch, en polyurethane waaks wurdt brûkt foar TPU masterbatch.
  • – Heat Stabilizers: Wurdt brûkt om pigment ûntbining en TPE-degradaasje te foarkommen by ferwurking op hege temperatuer. Common heat stabilizers include organic tin stabilizers (for TPU), hindered phenol antioxidants (for TPS, TPO), and phosphite antioxidants (for TPC, TPA).
  • – UV Stabilizers and Antioxidants: Used to improve the weather resistance and aging resistance of colored TPE products, preventing color fading and performance degradation under sunlight and oxygen. For outdoor applications (such as automotive exterior parts), UV absorbers and hindered amine light stabilizers (HALS) are added.
  • – Lubricants: Used to reduce friction between materials and extrusion equipment (skroef, barrel, die kop), improve processing fluidity, and avoid material sticking to equipment. Algemiene smeermiddelen binne stearinezuur, kalsiumstearaat, 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 (foar elektryske komponinten), 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, pigminten, and additives must be compatible with the target TPE to avoid reducing the material’s elasticity, fleksibiliteit, en meganyske eigenskippen. Bygelyks, using a non-polar carrier for polar TPU will lead to poor compatibility and pigment migration.

2.2.2 Match Heat Resistance.

The pigments and additives must have heat resistance matching the TPE processing temperature. Bygelyks, TPC masterbatch uses high-temperature resistant pigments (heat resistance ≥280℃) to avoid decomposition during processing.

2.2.3 Optimize Dispersibility.

The pigment content and dispersant dosage are adjusted to ensure uniform dispersion. Hege konsintraasje masterbatch (pigment ynhâld 50%-70%) fereasket mear dispersanten en bettere mingmooglikheden, wylst lege-konsintraasje masterbatch (10%-30%) rjochtet him op komptabiliteit.

2.2.4 Minimalisearje ynfloed op TPE-eigenskippen.

De masterbatch moat de elastisiteit fan 'e TPE net signifikant beynfloedzje, kompresje set, of abrasion ferset. Bygelyks, oermjittige dispersanten of smeermiddelen kinne de meganyske sterkte fan 'e TPE ferminderje.

2.2.5 Miljeubeskerming Compliance.

De formulearring moat foldwaan oan wrâldwide noarmen foar miljeubeskerming, it foarkommen fan giftige of skealike stoffen (lykas swiere metalen, ftalaten) dat koe beheine merk tagong.

2.3 Ferwurkingseasken fan TPE Masterbatch

TPE masterbatch ferwurking wurdt benammen útfierd mei help fan twin-screw extrusion technology, dat fereasket strange kontrôle fan grûnstoffen pretreatment, premixing, extrusion parameters, en postferwurking om produktkwaliteit te garandearjen. De wichtichste ferwurkingseasken binne as folget:

2.3.1 Raw Material Pretreatment.

TPEs (especially TPU, TPA) hawwe hege wetterabsorption, so all raw materials (TPE carrier, pigminten, tafoegings) moat goed droech wurde foardat ferwurking. The drying temperature and time are determined by the material type: TPU/TPA is dried at 100-120℃ for 6-8 oeren, TPS/TPO is dried at 80-100℃ for 3-5 oeren, and pigments are dried at 60-80℃ for 2-4 oeren. The moisture content of dried raw materials should be controlled below 0.1% (0.05% for TPU/TPA).

Derneist, pigments with large particle sizes or agglomerates should be crushed and sieved (20-40 mesh) to improve dispersibility, and impurities (metal particles, stof) should be removed to avoid wear on extrusion equipment and defects in masterbatch.

2.3.2 Premixing.

The dried raw materials (pigminten, carrier, tafoegings) are mixed in a high-speed mixer according to the formula ratio to form a uniform preliminary mixture. The premixing parameters are adjusted based on the TPE type: mixing speed 800-1200 rpm, mingen tiid 5-10 minuten, mixing temperature 40-60℃. For high-concentration masterbatch or high-viscosity TPE carriers, the premixing time is extended, and dispersants are added first to coat the pigments, improving dispersibility.

2.3.3 Extrusion Parameters Control.

Twin-screw extrusion is the core step of TPE masterbatch processing, and the key parameters (temperatuer, screw snelheid, extrusion druk, feeding speed) must be precisely controlled to match the TPE type:

  • – Temperatuer kontrôle: The barrel is divided into 4-6 temperatuer kontrôle seksjes (feeding seksje, melting seksje, mingen seksje, homogenizing seksje, die kop seksje). The temperature of each section is adjusted according to the TPE processing temperature. Bygelyks, 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 (btw, 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 druk: 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. Foar hege viskositeit TPE's, 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 (particle size 2-5mm), screened (to remove unqualified particles), and packaged (sealed and moisture-proof packaging). For moisture-sensitive TPE masterbatch (TPU, TPA), the finished product is dried again before packaging to prevent moisture absorption.
