摘要
研究阻聚剂ZJ-701在过氧化物硫化体系胶料中的防焦烧作用。结果表明:在甲基乙烯基硅橡胶、丁苯橡胶和三元乙丙橡胶中加入阻聚剂ZJ-701,可以有效延长胶料的焦烧时间,但同时会降低交联效率;阻聚剂ZJ-701的防焦烧效果与橡胶分子链间的交联反应活性有关,反应活性越低,硫化初期的防焦烧效果越好。
The anti-scorching effect of polymerization inhibitor ZJ-701 in the peroxide cured compounds was studied.The results showed that,by adding ZJ-701 in methyl vinyl silicone rubber(MVQ),butadiene styrene rubber(SBR)and ethylene propylene terpolymer(EPDM),the scorching time of three compounds was effectively extended,but at the same time the crosslinking efficiency was reduced.The anti-scorching effect of ZJ-701 was related to the cross-linking reaction activity between rubber molecular chains.The lower the reaction activity,the better the anti-scorching effect at the initial vulcanization stage.
