Liquid silicone rubber compositions and methods for the preparation thereof |
摘要 |
Liquid silicone rubber compositions that prior to cure have good fluidity and excellent moldability and that cure into a highly flame retardant silicone rubber with excellent high-voltage electrical insulating properties. The liquid silicone rubber compositions comprise: (A) polyorganosiloxane; (B) fumed silica; (C) surface-treated zinc carbonate powder as afforded by treating the surface of (a) zinc carbonate powder or basic zinc carbonate powder with (b) an organosilicon compound selected from organosilanes, organosilazanes, and organosiloxane oligomers; (D) polyorganohydrogensiloxane; and (E) platinum catalyst. The liquid silicone rubber compositions may further comprise (F) surface treated aluminum hydroxide powder, (G) triazole compound, and (H) a reaction mixture of (d) platinum compound and (e) 3,5-dimethyl-1-hexyn-3-ol.
