摘要
研究烷基酚醛树脂用量、硫化剂DCP/TAIC用量比、增塑剂用量以及硫化工艺对三元乙丙橡胶(EPDM)粘合性能的影响。结果表明:烷基酚醛树脂可提高EPDM与聚酯线绳的粘合性能;随硫化剂DCP/TAIC用量比增大,EPDM与聚酯线绳的粘合性能先提高后保持不变,用量比为9/1时综合性能最佳;EPDM与聚酯线绳的粘合性能随增塑剂2280用量增大几乎呈线性下降趋势;在充分硫化情况下,低温长时间硫化和高温快速硫化工艺对粘合性能影响不大,为提高生产效率,EPDM汽车多楔带可采用高温快速硫化工艺。
The effects of the amount of alkyl phenolic resin,the blending ratio of curing agent DCP and TAIC,the amount of plasticizer and the vulcanization process on the adhesion properties of ethylene propylene diene monomer(EPDM) with polyester cord were studied. The results showed that alkyl phenolic resin could improve the adhesion between EPDM compounds and polyester cords. With the increase of the blending ratio of the curing agent DCP and TAIC,the adhesion between EPDM compounds and polyester cords first increased and then remained unchanged,and the best comprehensive performance was obtained when the blend ratio was 9/1. The adhesion properties of EPDM with polyester cord decreased almost linearly with the increase of the amount of plasticizer 2280. When EPDM compound was fully vulcanized,the vulcanized rubber from different vulcanization processes,such as low temperature long-term vulcanization and high temperature rapid vulcanization,had similar adhesion properties with polyester cord. However,in order to increase the production efficiency,high temperature rapid vulcanization process was used for EPDM automotive V-ribbed belts.
