摘  要:研究了NR生胶类型对胶料及橡胶减振垫产品性能的影响。结果表明,相比于恒粘橡胶CV60和全乳胶SCRWF,脱蛋白天然橡胶(DPNR)的力学性能、回弹性、压缩永久变形、蠕变以及疲劳性能均最佳,但硫化速度及交联程度偏低;采用DPNR制备的橡胶减振垫产品的动刚度、蠕变以及疲劳性能均优于其他两种胶料,静刚度基本相当。DPNR更适宜制备高性能长寿命的减振橡胶制品。The effect of natural rubber(NR)raw rubber type on the properties of compound and damping gasket products was studied.The results showed that the mechanical properties,resilience,compression set,creep and fatigue performance of DPNR were better than CV60 and SCRWF,but the vulcanization rate and the degree of crosslinking were relatively low.The dynamic stiffness,creep and fatigue performance of damping gasket products prepared with DPNR were better than CV60 and SCRWF,while static stiffness was equivalent.DPNR was more suitable for preparing high-performance and long-life damping rubber products.
