▎ 摘  要

NOVELTY - Flame-retardant liquid silicone rubber comprises A component and B component at weight ratio of 100:1-10. The A component comprises 55-75 pts. wt. hydroxy- terminated polydimethylsiloxane, 3-5 pts. wt. hexabromocyclododecane, 1-3 pts. wt. modified kaolin, 3-5 pts. wt. nano silicon dioxide, 6-9 pts. wt. modified graphene oxide and 2-5 pts. wt. silicone oil emulsion. The B component comprises 1-3 pts. wt. catalyst and 2-5 pts. wt. cross-linking agent. USE - Used as flame-retardant liquid silicone rubber. ADVANTAGE - The flame-retardant liquid silicone rubber has good heat resistance, good toughness, good tensile strength and good flame retardant property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing flame-retardant liquid silicone rubber, comprising (1) adding 6-9 pts. wt. modified graphene oxide into 55-75 pts. wt. hydroxy terminated polydimethylsiloxane, stirring and dispersing to obtain mixture A; and (2) adding 1-3 pts. wt. modified kaolin, 3-5 pts. wt. nano silicon dioxide and 2-5 pts. wt. silicone oil emulsion, adding into the mixture A, stirring for 5-15 minutes, dispersing uniformly to obtain the A component, mixing 7-9 pts. wt. crosslinking agent and 1-3 pts. wt. catalyst obtain the B component, mixing the A component and B component finally at weight ratio of 100:1-10 uniformly.
