| 摘 要： | 以12-羟基硬脂酸、Boltorn H20超支化聚酯和甲苯二异氰酸酯为原料,合成超支化分散剂（HBD）,研究了HBD处理CaCO3粉体后对PP/CaCO3结构与性能的影响。结果表明,经HBD处理CaCO3粉体后的PP/CaCO3的冲击强度、弯曲强度分别比未处理的提高了52.8%和22%,加入少量HBD也有利于提高PP/CaCO3的热性能。

| Abstract: | A kind of hyperbranched dispersant(HBD) was synthesized with 12-hydroxy stearic acid,Boltorn H20 hyperbranched polyesters and toluene diisocyanate.The effects of the calcium carbonate powder treated with HBD on structure and properties of PP/CaCO_3 were studied.The results show that the impact strength and flexural strength of the PP/CaCO_3 composites treated with HBD are higher than those of unmodified system,which increase by 52.8%and 22%,respectively.In addition,addition of a few of HBD is helpful to imp... |
