Efficient flame-retardant silicon resin composite outdoor insulator castable and preparation method thereof

The invention relates to the technical field of outdoor high-voltage insulating materials, in particular to an efficient flame-retardant silicon resin composite outdoor insulator castable and a preparation method thereof. The invention relates to an efficient flame-retardant silicon resin composite outdoor insulator castable, which is prepared from the following raw materials in parts by mass: 25 to 35 parts of silicon resin, 45 to 55 parts of filler, 5 to 10 parts of reinforcing agent, 2 to 5 parts of auxiliary agent and 3 to 5 parts of flame retardant, the particle size of the aluminum hydroxide is 200-300 nanometers, and the particle size of the graphene oxide is 10-20 microns. According to the invention, aluminum hydroxide modified graphene oxide is used as a flame retardant, and a composite system between aluminum oxide and graphene oxide is formed in the composite material, so that an excellent flame-retardant effect is achieved. 本申请涉及户外高压绝缘材料技术领域，尤其涉及一种高效阻燃硅树脂复合户外绝缘子浇注料及其制备方法。一种高效阻燃硅树脂复合户外绝缘子浇注料，包括以下质量
