▎ 摘　　要

NOVELTY - Preparation of composite material of silicone polymer and graphene oxide comprises reacting graphene oxide dispersion liquid of tetrahydrofuran with silicone polymer at 60-75 degrees C for 4-5 hours. The mass ratio of graphene oxide and silicone polymer is 0.05-0.5:0.3. The content of graphene oxide in graphene oxide dispersion liquid of tetrahydrofuran is 0.1-0.5 mass%. USE - The method is for preparation of composite material of silicone polymer and graphene oxide, used for epoxy resin material (claimed). ADVANTAGE - The composite material improves the tensile strength of the epoxy resin and enhances the toughness of the epoxy resin. The epoxy resin has high strength and impact resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) composite material of silicone polymer and graphene oxide; (2) epoxy resin material with high strength and impact resistance comprising epoxy resin matrix material and silicone polymer/graphene oxide nanocomposite material uniformly dispersed in the epoxy resin matrix material, where the mass of the silicone polymer/graphene oxide nanocomposite material is 0.35-0.85 mass% of the mass of the epoxy resin matrix material; and (3) preparation of the high-strength impact-resistant epoxy resin material comprising adding the silicone polymer/graphene oxide nanocomposite material into the epoxy resin matrix material, evaporating the solvent at 50-70 degrees C, vacuumizing and removing air bubbles and casting to obtain the product.
