环氧型丙烯酸酯橡胶的硫化及补强研究

本文研究了硫化剂用量、硫化时间、硫化温度、硫化压力、炭黑种类及用量对环氧型丙烯酸酯橡胶硫化胶的力学性能等的影响,结果表明随硫化剂用量逐渐增大,橡胶的拉伸强度先增后减,断裂伸长率逐渐减小。最佳硫化条件为：硫化剂1.5份、一段硫化时间为20min、二段硫化时间为2h、硫化压力6.0MPa、硫化温度170℃。随补强剂用量逐渐增大,橡胶的拉伸强度先增后减,断裂伸长率逐渐减小。补强炭黑最佳种类为N330和用量为55份。;This article studied the influences of the amount of vulcanization agent, curing time, curing temperature, curing pressure, type and amount of carbon black on the mechanical properties of vulcanizated ACM. The result showed that with the increase of vulcanization agent, the tensile strength first increased then decreased, while the break elongation rate kept dropping. It was shown that optimum curing conditions were 1.5phr of vulcanization agent, 20min of first stage of vulcanization, 2h of second stage of vulcanization, 6.0MPa of curing pressure and 170℃ of curing temperature. With the increase of reinforcing Agent, the tensile strength first increased then decreased, while the break elongation rate kept dropping. The best type and optimum amount of reinforcing carbon black was N330 and 55phr respectively
