摘要
研究炭黑对天然橡胶(NR)蠕变性能的影响。结果表明:随着炭黑粒径增大、比表面积减小,胶料的F_(max)减小,t_(10)和t_(90)延长,结合胶含量减小;炭黑N330与N774胶料的抗蠕变性能相当,炭黑N990胶料的抗蠕变性能较差,炭黑N550胶料的抗蠕变性能较好;采用炭黑N550胶料的发动机悬置总成橡胶件蠕变量小,动刚度变化率小,抗蠕变性能好。
The effect of carbon black on the creep properties of natural rubber（NR） was studied. The results showed that with the increase of the particle size and decrease of the specific surface area,the F（max） of the compound decreased,t（10） and t（90） increased,and bonding rubber content decreased. It was found that the compounds with carbon black N330 and N774 showed similar creep resistance,the compound with carbon black N990 showed poor creep resistance,and the compound with carbon black N550 possessed good creep resistance. The compound with carbon black N550 was suitable for the application in engine mount assembly,which had low creep rate and small change rate of dynamic stiffness.
