摘　　要：针对目前阻燃发泡液体硅橡胶成本高、制备繁琐及发泡不稳定的问题,本研究以TD-50聚甲基乙烯基硅氧烷为基础原料,加入氢氧化铝等阻燃物制备基胶。随后,向基胶中添加羟基硅油、铂配合物和抑制剂,搅拌得到A胶。同时,取基胶添加含氢硅油作为交联剂,制得B胶。将A胶和B胶以质量比1∶1混合,利用铂配合物的催化作用使混合胶固化,获得室温固化阻燃液体硅橡胶发泡材料。该方法不仅降低了生产成本,简化了制备过程,还提高了发泡稳定性。Because of high cost,cumbersome steps,and unstable foaming in flame-retardant liquid silicone rubber(LSR)foam,we used TD-50 as the base rubber and aluminum hydroxide as flame retardant to prepare the base compound.Subsequently,component A was obtained by mixing of hydroxyl silicone oil,platinum complex and inhibitor.Meanwhile,component B was obtained by hydrogen silicone oil as cross-linking agent.By mixing component A and B at a mass ratio of 1∶1 and leveraging the catalytic effect of the platinum complex,thus the RTV flame-retardant LSR foam was prepared.This method not only simplifies the process,reduces the production cost,but also improves the foaming stability.
