         compatibilizer also increase agent. plastics blending, modified, alloy key/critical is solution different polymer versus property, add amount compatibilizer make its tool has good versus property, positive solution this 课题.

         how to positive selection compatibilizer, separation different separation property can, anti product in most use process in is very important.

         according to compatibilizer polymer/macromolecule between function 特征, compatibilizer can separation is non reaction type compatibilizer and reaction type compatibilizer type.

         non reaction type compatibilizer

         non reaction type compatibilizer is that 本身并不含 reaction 基因, in polymer mixing/compounding process add chemical reaction copolymer.

         from structure upper 看, non reaction type compatibilizer large more is copolymer and grafting copolymer or random copolymer, 如EAA, EEA, EVA, CPE, SEBS and other.

        但 this category of compatibilizer need add amount relatively large.

         reaction type compatibilizer

         reaction type compatibilizer main/primary through reaction in mixing/compounding raw materials polymer chemical reaction formed chemical improve/increase versus property.

         generally is large separation type, its active property can can in separation 子 末端, can in separation 子 侧链 upper. its large separation 子主链 can and blending system in less types polymer/macromolecule same, can different. in different lower, its large separation 子主链应 and blending system in less types polymer/macromolecule has relatively good versus property.

         this category of compatibilizer advantages is function efficiency high, need add amount less, disadvantages is reaction relatively large, for mixing/compounding conditions requirements versus for relatively high.

         main/primary classification and product types

        01, ring acid type (MAH)

         ring acid type type reaction type compatibilizer is currently most commonly used type reaction type compatibilizer. its in, maleic anhydride grafted to polyolefin compatibilizer is 主, its grafting rate generally is 0.8%-1.0%, main applications polyolefin plastics modified. will maleic anhydride grafted to PS or 以PS is copolymer reaction type compatibilizer, can used for PA/PC, ABS/GF, PA/ABS modified, blending or alloy. generally use amount 5%-8%.

        02, acid type

        羧 acid type in table/sheet product is acrylic type compatibilizer. usually is will acrylic grafting to polyolefin resin upper, applications large and acid type same.

        03, ring oxygen type

         ring oxygen type reaction type compatibilizer is ring oxygen resin or tool has ring oxygen 基 化 combined material and other polymer grafting copolymer formed. this category of reaction type compatibilizer can to good versus function.

        04, 恶唑啉 type

         use 恶唑啉 grafting PS,即RPS, is types comparison important compatibilizer, grafting rate is 1%, features is application areas relatively 广, not only can and generally 含氨基 or polymer reaction, also can and 含羰基, acid 酐, ring oxygen reaction, formed grafting copolymer. therefore, it can used for PS and multiple engineering plastics or modified polyolefin resin. in addition, it also can "就 " versus 容化, used for plastics modified, blending and alloy.

        05, amine type

        酰亚 amine type is modified polypropylene (PP) acid ester, main/primary suitable for PA/PO, PC/PO, PA/PC and other engineering plastics alloy or blending.

        06, acid ester type

         formed separation is 间-异 propylene 基-2, 2-二甲基苯酰异氰 acid ester. can used for has and engineering plastics alloy.

        07, low separation type

         low separation type compatibilizer is reaction type compatibilizer, reaction type mono and low molecular weight polymer, 包括一 can and plastics combined formed 一 组 separation versus 容, and 另一组 separation reaction, crosslinked or combined, from formed plastics alloy has machine and machine combined material. this 样, not only manufacturing plastics alloy process, but also raw materials easy, cost relatively low. 不, for extrusion machine requirements relatively high, using/adopting mixing/compounding type extrusion machine, is production low separation compatibilizer important key/critical.

         which combined need compatibilizer

        01, plastics alloy

         compatibilizer for alloy technology micro versus structure to very good adjustment and control function, from make blending material achieve high property can and function 化 效果. compatibilizer widely used in PP/PE, PP/PA, PA/PS, PA/ABS, ABS/PC, PBT/PA, PET/PA, PP/POE, PE/EPDM, TPE/PU and other alloy.

        02, polymer modified

         due to compatibilizer is active 跃自由基 separation 子羧基掺入 non property and property polymer between 起"桥梁" function, will its modified formed is property polymer, again make its and property polymer blending, between reaction obtain good modified blending 效果.

        03, recycling waste plastics

         utilizing compatibilizer recycling waste plastics, make formed is new plastics alloy or new modified plastics, is " waste material comprehensive utilizing " comparison good can method, can solution " white 污染" issues, tool has very large 社会效益 and enterprise 经济效益. in outer already has very more 先例, Netherlands 国家矿业 company production BENNET compatibilizer, is used for recycling waste plastics recycled specialized compatibilizer, can types or multiple different product types, different property 质 旧 plastics, polyolefin plastics and engineering plastics material blending recycled, add 5%-10% compatibilizer as is versus or versus between interface 层, compatibilizer combined force property versus 容基团 efficiency, made formed is types new plastics alloy or modified plastics.

        04, plastics and filler 偶联

         compatibilizer also large separation coupling agent. due to tool has polymer/macromolecule separation and polymer/macromolecule polymer versus 容, therefore, compatibilizer for plastics and filler between efficiency excellent, can used for PE/CaCO3, PE/ slip powder, PA/GF and other 偶联处理, 效果良 good.

        05, property resin toughened

         thermoplastic property elastomer, tool has good soft/flexible property, high elastic property and low temperature property can, add amount compatibilizer can as is PP, PE, PS, PA, PC and other plastics toughening agent. compatibilizer positive is this toughening agent most key/critical property "核", " housing/shell " versus function. 如MAH grafting EPDM toughening agent, can in -45℃ temperature degree lower, maintain excellent physical properties and tough property can. generally use amount 5%-10%.

        06, improvement plastics other property can

         compatibilizer also can used for improvement plastics bonding property, anti-static property, printing property, gloss property and other property can.
