| Abstract: | The stabilization mechanism of polyurethances were introduced. Some kinds of ultraviolet absorbents, light stabilizer, antioxidant used for polyurethane were summarized.The influences of ultraviolet (UV-571, UV-328), antioxidant (Irganox 1010,Irganox 1135,Irganox 3125), HALS light stabilizers (UV-770,UV-765)on improving light aging resistance properties of polyurethanes were discussed.The results show that using antioxidant, ultraviolet absorbent and HALS together have the best effect on maintaining light oxidative stabilization of polyurethanes. |
