摘　　要：为研究软硬段配比对聚氨酯弹性体的力学性能及其环境耐受性影响研究,选择了聚醚-二苯基甲烷-4,4’-二异氰酸酯(MDI)型聚氨酯弹性体为研究对象,通过对其软硬段配方的调整制备了系列聚氨酯弹性体,同时对包含力学性能在内的综合环境耐受性进行了研究,为应用于极端工况下的聚氨酯介电弹性体的基体优选提供参考。In order to study the effect of the ratio of soft and hard segments on mechanical property and environmental tolerance of polyurethane elastomer, polyether diphenylmethane-4,4’-diisocyanate(MDI) polyurethane elastomer was selected as the research object. Then,a series of polyurethane elastomers were prepared by adjusting the formula of soft and hard segments, and the comprehensive environmental tolerance including mechanical properties was studied. Such a comprehensive study of environmental aging properties provides a reference for the matrix optimization of polyurethane dielectric elastomer under extreme working conditions.
