白炭黑填充氯丁橡胶性能研究

Study on the Properties of Silica Rubber Filled with Chloroprene

研究了白炭黑用量对氯丁橡胶性能的影响。结果表明:随着白炭黑用量的增加,胶料的硬度、撕裂强度增加,白炭黑用量为30phr时,拉伸强度值最大。随着白炭黑用量增加,阿克隆磨耗性能先增加后降低,压缩永久变形先增加,30phr以后趋于稳定。

This paper studied the effects of silica on the properties of polychloroprene （CR）. The results showed that the hardness and tear strength increased with the amount of silica increasing, the tensile strength attained maximum at the dosage of 30phr silica. For Akron abrasion, with the increase of the amount of silica, it increased first and then decreased, and the compression set increased first and then went stabilized after 30phr of silica.
