热硫化硅橡胶废胶裂解回收环体的再利用

Reuse of the Cyclosiloxane Recovered from Waste HTV Silicone Gum by Splitting

采用碱催化法裂解热硫化硅橡胶生胶生产中的废胶并对裂解料进行二次精馏 ,去除高、低沸物杂质 ,使回收的混合环体可再次用于合成热硫化硅橡胶。

s:The waste gum produced in the fabrication of HTV silicone gum was splitted by alkline catalyst.The splitting products were redistilled to remove high and low boil impurity.And the recovered cyclosiloxane was reused as raw material of fabricating HTV silicone gum.
