摘要/Abstract

摘要： 以聚醚N-204、甲苯二异氰酸酯为原料，用1，4-丁二醇为扩链剂，填充经超声波分散、偶联处理的不同无机填料，分别合成填充型聚氨酯（PUR）弹性体。研究了填充型PUR弹性体的耐磨性、力学性能以及填料在弹性体中的分布状况。结果表明，不同无机填料在PUR弹性体中所表现出的性质不同，碳化硅主要提高了弹性体的耐磨性，而陶瓷微珠、玻璃微珠在增强增韧方面发挥了作用。

Abstract: The filled polyurethane elastomers were synthesized from polyether N-204，and toluene diisocyanate，with the chain extender of 1,4-butanediol and inorganic fillers treated by ultrasonic dispersion and coupling reaction. The wear resistance and mechanical properties of filled polyurethane elastomer as well as the distribution of fillers were studied. The results showed that the polyurethane elastomers possessed different properties with different inorganic fillers. Silicon carbide enhanced its wear resistance，while talc and micro glass bead improved its strength and tenacity.
