        PC/ABS copolymer is types property can excellent 良, price low engineering plastics, in industrial upper application 广泛. alloy in ABS组 separation can is PC/ABS alloy provide relatively good processing flow property, also can improve/increase alloy material low temperature resistance property can. PC/ABS alloy tool has complex micro structure, its micro structure improvement can significantly improve/increase alloy force property can.

        (1) raw materials property can

         different Brand PC and ABS resin blending alloy in property can upper has relatively large 差异. high content improve/increase PC/ABS system impact strong/high degree, large large loss versus 态间互容行 is, make alloy tensile property can reduce. therefore, selection 适当橡胶 content ABS, can make blending material impact strong/high degree obtain improve/increase, but also its flexural strength also 会出现协同 reinforcement. use low content ABS时, alloy flexural strength 会出现协同 reinforcement. another, high propylene 睛, low content and polymer/macromolecule amount ABS can make alloy resistant thermal properties improve/increase.

        (2)PC/ABS blending ratio for alloy property can effect/influence

        PC/ABS blending system versus property, force property can and system in separation content related. dry and other through adjustment PC and ABS resin blending ratio/proportion, separation obtain various different features PC/ABS alloy. PC/ABS alloy property can and ABS content property 关系, 近似服 from add and property, its overall property can 介于PC and ABS between, impact strong/high degree ratio has ultra- add and 效应〔即协同效应) and for resistant 效应.

        (3)第三组 separation effect/influence

         in PC/ABS alloy in add 入苯并噻唑, polyimide (PI) and other material can improve/increase alloy heat resistant property and heat stabilized property. in processing process in, add processing modifier ring oxygen 乙烷/ ring oxygen 丙烷嵌段 copolymer, MMA/St copolymer, 烯烃/ acrylic copolymer and other can improvement PC/ABS alloy flow property. in addition, is improve/increase PC/ABS alloy injection products strong/high degree, usually add 入PMMA,SAN,SBR, acrylic elastomer, low density polyolefin, ethylene / acrylic 醋/乙 acid, ethylene (醋) copolymer, PC/ ethylene type or grafting copolymer and other material 质.

        (4) processing process function

        PC and ABS blending equipment can selection di screw extrusion machine and has mixed combined device mono screw extrusion machine. JongHanChun认 is use 连续捏 combined extrusion machine relatively is 理想. in blending methods upper, blending mixing/compounding good. in blending in, separation material material need 经 两次 high temperature extrusion, can consumption high, easy make material material degradation, alloy property can decline.

         molding methods for PC/ABS alloy structure effect/influence very large, compression molding molding Sample can relatively good maintain alloy mixing/compounding 时 形 formed micro non versus dispersion 状态, injection molding 时, in high speed rate lower, dispersion 状态发生变化, to degree uniform separation understanding. therefore, types Sample impact strong/high degree has relatively large 差别, compression molding molding Sample impact strong/high degree high. PC in has water separation (含 water amount large 于0.03%)以 and high temperature (temperature degree high 于150℃) lower easy degradation, therefore in blending or molding front drying outer, also 应避免 hard acid type lubricant mixed 入, effect/influence products property can.
