摘　　要：背板用聚氨酯胶黏剂在贮存和使用过程中要经受热、光、空气和水等因素的作用,发生老化降解。了解聚氨酯的降解机理、聚氨酯的稳定化技术和稳定剂的使用方法等问题有比较长远的发展意义。因此,针对实际需要,本文以复合型聚氨酯树脂为基本原料,总结了温度、紫外线光照和水对聚氨酯老化的影响;研究了其热老化、光老化和水解的过程及相应的添加助剂解决的方法;考查了多种添加剂,如抗氧剂、抗水解剂及紫外线吸收剂等助剂对材料的耐老化性能和粘结强度的影响,最终筛选出能够提高聚氨酯材料粘结强度,且抗光老化、耐湿热性能优异的稳定剂最佳组合及其用量。The adhesives used in backboard of solar cell will be affected by heat, light, air and wet and other factors, and then degraded. It is significant to comprehend the degradation mechanism, stabilization mechanism, and the use of stabilizer. Therefore, the effect of temperature, UV-illumination, oxygen and vapor on polyurethane adhesive aging based on composite resin is summarized here. We explored the process ofthermai aging, photo aging （especially UV light） and hydrolysis, and also highlight the stabilization avenues of polyurethane aging and makes a brief introduction on some tr-aditional stabilizers and how to use them efficiently.
