SILICONE PREPREG; AND SILICONE RESIN PLATE, SILICONE METAL-CLAD LAMINATE, SILICONE METAL BASE BOARD AND LED MOUNTING BOARD WHICH ALL USE THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a silicone prepreg which is a base board material which is high in reflectivity in the visible light region, hardly causes deterioration, discoloration and a decrease in reflectivity due to heating and ultraviolet rays, high in heat resistance and heat release, and also high in reliability in solder connection to mounting parts; and to provide a silicone resin plate, a silicone metal-clad laminate, a silicone metal base board, and an LED mounting base board.;SOLUTION: Quartz glass cloth is impregnated with a silicone resin composition and then dried to obtain the silicone prepreg. In this case, the composition contains: (A) resin-structure organopolysiloxane comprising an R¹SiO_1.5 unit, an R²₂SiO unit and an R³_aR⁴_bSiO_(4-a-b)/2 unit; (B) resin-structure organohydrogenpolysiloxane comprising an R¹SiO_1.5 unit, an R²₂SiO unit and R³_cH_dSiO_(4-c-d)/2 unit; (C) a platinum group metal-based catalyst; and (D) a filler.;COPYRIGHT: (C)2013,JPO&INPIT
