相容剂的主要应用领域
一、相容剂应用于塑料合金
First, compatibilizer used in plastic alloy
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,从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 emergence of compatibilizer mainly for polymer materials, alloy technology services. The so-called polymer alloy, polymer material consisting of two or more than two kinds with different properties by blending and adding compatibilizer and get the corresponding multi component system, and polymer alloy, this blending, the key material is compatibilizer. Compatibilizer plays a very important role in adjusting and controlling the micro phase structure of alloy technology, so as to realize the high performance and function of blending materials. Compatibilizer is 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.
二、相容剂应用在回收废旧塑料
Two 、 compatibilizer used 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。
The compatibility of recycling waste plastics, make it become the new plastic alloy or new modified plastics, is the feasible way for the comprehensive utilization of waste "better, and can solve the problem of" white pollution "has great social benefits and economic benefits of enterprises. In foreign countries such as Holland has many precedents, produced by mineral company BENNET compatilizers, is dedicated for the recovery of waste plastic recycling compatilizers, can put two or more different varieties, different nature of the old plastic, such as recycled scrap blending polyolefin plastics and engineering plastics, adding 5%-10% compatibility interface as marine or island between the phases, play a compatibilizer bonding force of polar groups and the preparation efficiency of compatibility, become a kind of plastic alloy new or modified plastics.
三、相容剂应用于聚合物的改性
Three. Compatibilizer used in polymer modification
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 is with active free radicals from carboxyl incorporation of "bridge" between non-polar and polar polymers, the modification of modified polymer polarity, then the polymer polarity, between the two were made of blend of good results.
四、相容剂应用于塑料与填料的偶联
Four, compatibilizer used in plastic and packing coupling
相容剂又称大分子偶联剂,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 also called macromolecular coupling agent, polymer and polymer compatible with part, therefore, the compatibilizer on the coupling efficiency between the polymer and fillers is excellent, and can be used for treatment of PE/CaCO3, PE/, PA/GF, PRT/GT and talcum powder coupling effect is good.
五、相容剂应用于极性树脂的增韧
Five. Compatibilizer is applied to toughening of polar resin
热塑性弹性体,具有良好的柔软性、高弹性和低温性能,添加一定量的相容剂可以作为PP、PE、PS、PA、PC等塑料的增韧剂,而相容剂正是这些增韧剂的最关键性的“核”和“壳”相容作用。如EPDM接枝MAH增韧剂,可在-45℃的温度下,保持优良的物理性能和坚韧性能。一般用量5%-10%。
Thermoplastic elastomer with flexibility, high elasticity and excellent low temperature properties, toughening agent, compatibilizer can be used as PP, PE, PS, PA, PC and other plastics to add a certain amount of compatibilizer, and these are the most key toughening agent of "core" and "shell" compatibility. Such as EPDM grafted MAH toughening agent, at -45 degrees Celsius temperature, to maintain good physical properties and toughness. General dosage 5%-10%.
