三元乙丙橡胶/增粘树脂/酚类防老剂复合材料阻尼性能的研究

摘要

研究三元乙丙橡胶（EPDM）/增粘树脂/酚类防老剂复合材料的阻尼性能。EPDM的有效阻尼温度较低且区域较窄，EPDM与增粘树脂（增粘树脂BH-1、增粘树脂CH-FE、EPDM专用增粘树脂、增粘树脂CH-FR、GC增粘树脂和树脂王）、受阻酚类防老剂（防老剂1010、防老剂1076和防老剂1520）及其混合物制成的复合材料具有较好的高温阻尼性能和较宽的有效阻尼温域。%In this study, the damping properties of EPDM composites with tackifying resin and phenolic antioxidant were investigated. The tackifying resins included BH-1, CH-FE, EPDM tackiifer, CH-FR, GC resin and super tackiifer. The hindered phenolic antioxidants included antioxidant 1010, antioxidant 1076 and antioxidant 1520. The effective damping temperature of EPDM rubber was low and the range was narrow. With tackifying resin and hindered phenolic antioxidant, the effective damping temperature of EPDM composites shifted to higher temperature and the range became broader.
