摘要

简述了聚氨酯的结构以及与其它材料复合对改善聚氨酯弹性体耐热形变性能的影响。结构上从形成硬段和软段的原料出发，引入刚性结构，分别提高硬段和软段的耐温性，从而加强材料耐温性。聚氨酯分别与无机材料复合和有机材料复合，以及形成互穿网络结构，都可以提高聚氨酯复合材料的耐高温性能。

Abstract

In this paper

the effects of structure of polyurethane and the mixture of other materials with polyurethane on the heat-resistance of polyurethane elastomers were reviewed. The introduction of rigid groups

the structure of hard segment and soft segment all can improve the thermal stability of polyurethane. Both the mixture of inorganic materials

organic materials with polyurethane and the interpenetrating polymer networks can reinforce the heat-resistance of polyurethane.
