混炼硅橡胶的配合技术(九)

The blending technology of mixed silicone rubber (Ⅸ)

介绍了用2,4-二氯过氧化苯甲酰作硫化剂的挤出成形用混炼硅橡胶(包括低硬度混炼硅橡胶、不粘连芯线的混炼硅橡胶、高电气强度电线用混炼硅橡胶)的配制方法及改进其加工和表面性能的方法;同时,还介绍了用甲基苯甲酰类过氧化物作硫化剂时改进混炼硅橡胶表面性能的方法(包括添加含氢硅油、硅藻土、二烷基过氧化物或过氧化苯甲酰以及细化硫化剂粒子)。

The blending technology and the improvement of the mixed silicone rubber for extrusion molding with 2, 4-dichlorobenzoyl peroxide, including the low hardness mixed silicone rubber, the mixed silicone rubber with no connection with cored wires, high electric strength mixed silicone rubber. Meanwhile, the method of improving the surface property of the mixed silicone rubber for extrusion molding modified by methyl benzoyl peroxide, which include adding hydrogen-containing silicone fluid, diatomite, dialkyl peroxide, benzoyl peroxide or milled vulcanizing agent particles
