摘　　要：利用端羟基液体丁腈橡胶(HTBN)分别与二苯基甲烷二异氰酸酯(MDI)和对氯苯基异氰酸酯(4CPI)反应制备HTBN-聚氨酯(PU)和HTBN-4CPI两系列相容剂,研究其对采用机械共混法制备的丁腈橡胶(NBR)/PU复合材料性能的影响。结果表明:加入相容剂后,NBR和PU的相容性得到有效改善,NBR/PU复合材料的拉伸强度和储能模量增大,耐磨性能提高;当HTBN-4CPI质量分数为0.98%时,NBR/PU复合材料的拉伸强度和储能模量最大,耐磨性能最佳,其中拉伸强度增大35%,磨耗量减小56%。Two series of compatibilizers for nitrile rubber(NBR)/polyurethane(PU)composites were prepared by the reaction of hydroxy-terminated liquid nitrile rubber(HTBN)with diphenylmethane diisocyanate(MDI)and p-chlorophenyl isocyanate(4CPI),respectively,which were HTBN-PU and HTBN-4CPI,and their effects on the properties of NBR/PU composites prepared by mechanical blending method were studied.The results showed that the compatibility of NBR and PU was effectively improved with the addition of the compatibilizers,the tensile strength and storage modulus of NBR/PU composites increased,and the abrasion resistance was improved.When the mass fraction of HTBN-4CPI was 0.98%,the tensile strength and storage modulus of the NBR/PU composite were the largest,the abrasion resistance was the best.Compared with the composites without compatibilizer,the tensile strength increased by 35%and the abrasion loss was reduced by 56%.
