摘　　要：介绍了聚氨酯材料紫外光老化机理,综述了采用紫外线吸收剂(UV-P,UV-328,UV-B-97、UV-B-75等)、光稳定剂HALS(自由基捕捉剂)和抗氧剂(BHT,Chinox 30N,1135,IRGASTSAB PUR 67,IRGASTSABPUR 68等)提高聚氨酯光老化性能的研究进展。研究表明,组合使用各种稳定剂往往能够获得最佳效果。The UV - aging mechanism of the polyurethane material was introduced. The research progress of impro- ving the anti - UV aging propertis of polyurethanes using an ultraviolet absorber （ UV - P, UV - 328, UV - B - 97, UV- B -75, etc. ）, light stabilizers HALS （radical scavenger） and anti -the oxidants （BHT, Chinox 30N, 1135, Irgastsab PUR 67, Irgastsab PUR 68 etc. ） were reviewed. The study showed that the best results were often obtained by the combined use of a variety of stabilizers.
