摘要
简单介绍了聚氨酯的水解、热降解、热氧化降解和紫外线降解的反应机理。举例比较了加入或未加入稳定剂的聚氨酯弹性体在降解试验前后的拉伸强度及其它性能变化 ,指出了添加稳定剂可改善聚氨酯弹性体的抗降解稳定性。
A review is cited with 16 references. The mechanism of polyurethane degradation such as hydrolysis, thermolysis, oxidation degradation and photolysis were simply introduced. The comparison of strength and other properties of polyurethane elastomer which stabilizer were added or not between before and after degradation test were cited. It points out that addition of stabilizers can improve the degradation resistance of polyurethane elastomer.
