All aminosilane coupling agents can be used and are not particularly limited. The epoxy group-containing organopolysiloxane is not particularly limited as long as it is an organopolysiloxane containing an epoxy group in one molecule. In the reaction between the aminosilane coupling agent and the epoxy group-containing organopolysiloxane, the reaction product can be obtained by heating at 50 to 160 ° C. for 20 to 120 minutes, and the ratio of the two is not particularly limited. As the inorganic filler, any inorganic filler such as talc, clay, silica, calcium carbonate, aluminum hydroxide, glass fiber, asbestos fiber, ceramic fiber can be used and is not particularly limited. As the cross-linking agent and / or the curing agent, phenol resin, melamine resin, acrylic resin, isocyanate,
Amine-based curing agents, acid anhydrides, Lewis acid complex compounds and the like are used and are not particularly limited. As the curing accelerator used if necessary, phosphorus-based and / or tertiary amine-based curing accelerators and the like can be used. Thus, the above materials are blended, mixed, kneaded, pulverized, and further granulated as required to obtain an epoxy resin molding material for sealing. Further, regarding molding of the molding material for sealing, sealing molding is performed by compression molding, transfer molding, injection molding or the like.
