【1】塑料常用的增韧剂如何划分
[1] how to divide plastic commonly used toughening agents
1.橡胶弹性体增韧:EPR(二元乙丙)、EPDM(三元乙丙)、顺丁橡胶(BR)、天然橡胶(NR)、异丁烯橡胶(IBR)、丁腈橡胶(NBR)等;适用于所用塑料树脂的增韧改性;
1. Rubber elastomer toughening: EPR (binary ethypropylene), EPDM (EPDM), shunding rubber (BR), natural rubber (NR), isobutylene rubber (IBR), NBR, etc. Suitable for toughening modification of plastic resin used;
2.热塑性弹性体增韧:SBS、SEBS、POE、TPO、TPV等;多用于聚烯烃或非极性树脂增韧,用于聚酯类、聚酰胺类等含有极性官能团的聚合物增韧时需加入相容剂;
2. Thermoplastic elastomer toughening: SBS, SEBS, POE, TPO, TPV, etc. Polyolefin or non-polar resins are used for toughening, and the polymer, polyamide and other polymers that contain polar functional groups need to be added to the compatibilizer.
3.核-壳共聚物及反应型三元共聚物增韧:ACR(丙烯酸酯类)、MBS(丙烯酸甲酯-丁二烯-苯乙烯共聚物)、PTW(乙烯-丙烯酸丁酯—甲基丙烯酸缩水甘油酯共聚物)、E-MA-GMA(乙烯-丙烯酸甲酯—甲基丙烯酸缩水甘油酯共聚物)等;多用于工程塑料以及耐高温高分子合金增韧
3. The core - shell copolymer and reactive ternary copolymer toughening: ACR (acrylic acid esters), MBS (methacrylate - butadiene - styrene copolymer), PTW (ethylene - butyl acrylate, methyl acrylic glycidyl ester copolymer), E - MA - GMA (ethylene/methyl acrylate, methyl glycidyl ester of acrylic acid copolymer), etc.; It is used in engineering plastics and high temperature resistant polymer alloy
4.高韧性塑料共混增韧:PP/PA、PP/ABS、PA/ABS、HIPS/PPO、PPS/PA、PC/ABS、PC/PBT等;高分子合金技术是制备高韧性工程塑料的重要途径;
4. High toughness plastic mix and toughening: PP/PA, PP/ABS, PA/ABS, HIPS/PPO, PPS/PA, PC/ABS, PC/PBT, etc. Polymer alloy technology is an important way to prepare high toughness engineering plastics.
5.其它方式增韧:纳米粒子增韧(如纳米CaCO3)、沙林树脂(杜邦金属离聚物)增韧等;
5. Other ways of toughening: nano-particles toughening (such as nanometer CaCO3) and sarin resin (dupont metal depolymerization), etc.
【2】在实际的工业生产中,改性塑料的增韧大概分以下情况:
[2] in actual industrial production, the toughening of modified plastic is about the following:
a、合成树脂本身韧性不足,需要提高韧性以满足使用需求,如GPPS、均聚PP等;
A, the synthetic resin itself is not flexible enough, and it needs to improve its toughness to meet the needs of use, such as GPPS, polypp, etc.;
b、大幅度提高塑料的韧性,实现超韧化、低温环境长期使用的要求,如超韧尼龙;
B, improve the toughness of plastic substantially, and realize the long-term use of super toughening and low temperature environment, such as super tough nylon;
c、对树脂进行了填充、阻燃等改性后引起了材料的性能下降,此时必须进行有效的增韧。
C, the resin has been filled, flame retardant and other modification have caused the material's performance to decline, which must be effectively toughened.
