摘要
采用DCP或双2,5硫化CPE,通过改变硫化时间,研究CPE的硫化过程及性能。发现DCP对CPE的硫化速度快、硫化胶的物理机械性能好,但易使硫化胶产生异味;使用双2,5作硫化剂,则不产生异味,但其硫化速度较慢,双2,5的用量一般在4～4 5份之间为宜。
The vulcanization process and behavior of vulcanizated CPE were investigated by varing the curing time after adding DCP or 2,5-dimethyl-2,5-bis(tert-butyl peroxide)hexane.It was found that the curing rate of the vulcanizate was improved,the physical property was good,but the foreign taste was easy to form after adding DCP.Using 2,5-dimethyl-2,5-bis(tert-butyl peroxide)hexane as curing agent,there was no foreign taste,but the curing speed was slow,the suitable amount of 2,5-dimethyl-2,5-bis(tert-butyl peroxide)hexane was 4～4.5phr.
