摘　　要：目的:测定SY-1、B、C硅橡胶的硫化时间。方法:硫化仪测定并绘制出硫化温度为80℃时3种硅橡胶的硫化曲线。结果:3种硅橡胶的硫化曲线大体上均在30min时进入平坦期,即硫化仪测得硫化温度为80℃时,正硫化时间为30min。结论:SY-1、B和C硅橡胶具有相近的硫化时间,满足复合型硅橡胶并用的共硫化时间要求。Objective： To measure respectively vulcanizing time ofthree types of Room Temperature Vulcanizing silicone elastomers that were chosen as the blending components. Methods： The vulcanization curve was drawn by vulka meter. Results： The vulcanization curve of SY-1, B and C silicone elastomer reflected evenness, i.e. optimum cure point was 30min when vulcanizing temperature was 80℃. Conclusion： The optimum cure point of SY-1, B and C was similar, which meant that any two of them can realize co-vulcanization.
