摘要
对充油SBS的变色机理进行了研究 ,并提出了相应的解决措施。充油SBS在生产过程中的变色主要是由于偶合后残存的SB活性链与防老剂 10 76的酯基反应引起的 ;影响充油SBS光稳定性的关键因素是填充油中的芳烃含量 ;向充油SBS中填加光稳定剂 ,是提高充油胶光稳定性的重要措施 ,UV
A detailed research of discolorment mechanism on oil-extended SBS is conducted and the resolvents are given out. The discolorment in procedure of oil-extended SBS was mainly caused by the reaction of Antioxidant 1076 and vestigial active SB after the coupling reaction. The content of aromatichydrocarbon in extender oil was the key factor which influenced the light stability of oil-extended SBS greatly. It was an important way to improve the light stability by adding photostabilizer in oil-extended SBS. Photostabilizer UV-P could greatly improve the light stability of oil-extended SBS.
