摘　　要：聚氨酯合成革有耐油、耐磨、耐寒、耐屈曲、机械强度好等优点,但也容易发生老化。分析其老化原因,热、光、水和空气中潮气等均会引起其老化。改善PU耐老化性能,可采用以下方法:加添加剂法,如使用热稳定剂、光稳定剂及水解稳定剂。另外,也可通过改变单体结构与合成方法从根本上加以解决。Though polyurethane leather with its characteristic advantages of resistance to oil, abrasion, cold, flexion, and good mechanical strength, it has disadvantage of easily ageing. Based on analysis, the factors caused ageing are heat, light, water and moisture. The methods of increasing ageing resistance of polyurethane is listed as follows: using addition agent, heat stabilizer, light stabilizer, hydrolytic stabilizer, or even modifying monomer structure and changing synthetic method.
