【摘要】 本工作在宽切变速率范围内研究了异戊橡胶炭黑混炼胶的流变性质和动态力学性质以及改进剂N,4-二亚硝基-N-甲基苯胺的作用。结果表明,在上述两种性质方面,异戊橡胶与天然橡胶有较大差距。由于改进剂强化了异戊橡胶的炭黑效应,使异戊混炼胶的性质,例如挺性得到了改善。更多还原

【Abstract】 This paper studies the rheological and dynamic-mechnical behaviors of carbon black mixed polyisoprene rubber (IR) , and the effect of modifier N,4-dinitroso-N-methyl-phenylamine on these two properties in a wide range of shear rate 3.73×10-3-1.07×l03 sec-1. The data obtained indicate that nature rubber is comparably superior to polyisoprene in terms of rheological and dynamic-mechanical properties. However, the properties of carbon black mixed IR, such as resistance to flow at very low shear rates, are improved due to the increased reinforcing action between black carbon and IR caused by the modifier.更多还原
