摘要
以三元乙丙橡胶(EPDM)为主胶品种,骨架材料选用EPDM浸胶处理的高模量低收缩聚酯线绳,表面织物选用涤棉布,在压缩层胶料配合中加入预处理短纤维,研制出一种新型耐热EPDM汽车多楔带产品。所研制的EPDM多楔带采用四轮疲劳试验机进行动态疲劳寿命测试,运行450h停止试验,检查皮带完好,未出现任何裂纹、掉楔、起球和断裂等失效现象,并且聚酯线绳界面粘合良好,完全满足现代汽车对传动带的要求。
A new kind of heat-resistant EPDM motor V-ribbed belt product was developed,and the EPDM V-ribbed belt was made using EPDM as the main rubber,the HMLS PET cord dipped with EPDM adhesive latex as the bone material,pretreated short fiber in compressed layer rubber compounding.The results showed that the compressed layer vulcanizate had perfect mechanical properties after thermal ageing,and the developed EPDM V-ribbed belt still had smooth surface and the interface adhesion between rubber and PET cord was still good after 450 hours of fatigue life testing.
