摘要 分析了微孔聚氨酯弹性体材料在日光照射下发生光老化的原因。考察了抗氧剂 2 6 4(BHT)、紫外线吸收剂UV 5 31、UV 9、UV P对提高材料抗光老化性能的影响 ,实验结果表明 ,BHT与UV P并用时材料具有良好的光稳定性 ,机械性能保持率较高。 The light aging mechanism of microcellular polyurethane elastomer exposed to daylight was introduced. The influences of antioxidant 264(BHT), ultraviolet absorbent UV 531?UV 9?UV P on improving light aging resistance properties of MPUE material was investigated. The results indicate that using antioxidant 264(BHT) and ultraviolet absorbent UV P together have the best effect on maintaining mechanical properties and ultraviolet stabilization.
