相容剂应用
Application of compatibilizers
（1）应用于塑料合金
(1) Applied to plastic alloys
相容剂的出现主要是为高分子材料合金技术服务的。所谓高分子合金，即由两种或两种以上具有不同性质的高分子材料经共混并采用相应的相容化技术而得到的多相多组分体系。而这样的高分子合金、共混、改性的重要关键材料就是相容剂。相容剂对合金技术的微观相态结构起到很好的调整和控制作用，而使共混材料实现高性能化和功能化的效果。相容剂广泛应用于PP/PE、PP/PA、PA/PS、PA/ABS、ABS/PC、PBT/PA、PET/PA、PP/POE、PE/EPDM、TPE/PU等合金。
The appearance of compatibilizers mainly serves the technology of polymer alloy. Polymer alloys are multi-phase and multi-component systems obtained by blending two or more polymer materials with different properties and adopting corresponding compatibility techniques. The compatibilizer is the key material for such polymer alloys, blending and modification. The compatibilizer plays a very good role in adjusting and controlling the micro-phase structure of alloy technology, and makes the blend material achieve high performance and functionalization. Compatibilizers are 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 alloys.
（2）应用于聚合物的改性
(2) Modification of polymers
由于相容剂是以活跃自由基分子羧基掺入非极性与极性聚合物之间起“桥梁”作用，将其改性成为极性的改性聚合物，再使其与极性的聚合物共混，两者之间进行反应而制得良好的改性共混效果。
Because the compatibilizer acts as a bridge between non-polar and polar polymers by incorporating carboxyl groups of active free radicals, it is modified into polar modified polymers, which are then blended with polar polymers, and a good modified blending effect is obtained by the reaction between the two.
（3）应用在回收废旧塑料
(3) Application in Recycling Waste Plastics
利用相容剂回收废旧塑料，使之成为新的塑料合金或新的改性塑料，是“废物综合利用”比较好的可行办法，并可解决“白色污染”问题，具有很大的社会效益和企业经济效益。在国外已有很多先例，如荷兰国家矿业公司生产的BENNET相容剂，就是用于回收废旧塑料再生的专用相容剂，可以把两种或多种不同品种、不同性质的旧塑料，如聚烯烃塑料与工程塑料的边角料的共混再生，添加5%-10%相容剂作为海相或岛相之间的界面层，发挥相容剂的键合力极性相容基团效率，而制备成为一种新的塑料合金或改性塑料。
Recycling waste plastics by using compatibilizers to make them new plastic alloys or new modified plastics is a better feasible way of "comprehensive utilization of waste" and can solve the problem of "white pollution", which has great social and enterprise economic benefits. There are many precedents abroad, such as BENNET compatibilizer produced by Dutch National Mining Corporation, which is a special compatibilizer for recycling waste plastics. It can be used to blend two or more kinds of old plastics with different properties, such as polyolefin plastics and engineering plastics, and add 5%-10% compatibilizer as the interface layer between sea and island, so as to play the role of compatibilizer. The bonding force is POLARLY compatible with the group efficiency, and is prepared into a new plastic alloy or modified plastic.
（4）应用于塑料与填料的偶联
(4) Coupling of plastics and fillers
相容剂又称大分子偶联剂。由于具有高分子部分与高分子聚合物相容，因此，相容剂对聚合物与填料之间的偶联效率优异，可用于PE/CaCO3、PE/滑石粉、PA/GF、PRT/GT等偶联处理，效果良好。
The compatibilizer is also called macromolecule coupling agent. Because the polymer is compatible with the polymer, the compatibilizer has excellent coupling efficiency between the polymer and filler. It can be used in PE/CaCO3, PE/talc powder, PA/GF, PRT/GT and other coupling treatments with good results.
