三元乙丙橡胶为基材的高模量汽车V带的研究

Study on High Modulus Auto V-belt based on the Material of EPDM

由于发动机周围的工作温度越来越高,用氯丁橡胶(CR)制成的汽车V带(包括汽车多楔带)已不能满足要求,三元乙丙橡胶(EPDM)是非常合适的替代材料。本研究考察了EPDM聚合物参数对汽车V带性能的影响。采用甲基丙烯酸锌(ZDMA)对EPDM进行增强,制备高模量V带,并研究了ZDMA对EPDM与织物之间黏合性能的影响。

With the increase of working temperature around auto engine,CR based V-belts（Including automotive V-ribbed belts） can not meet the requirement anymore,and the EPDM is the best substitute,the EPDM parameters effect on V-belts mechanical property is investigated.ZDMA is used to reinforce EPDM to prepare high modulus V-belts,and the ZDMA effect on adhesion between EPDM and fabric is investigated.
