Composite material for electrical apparatus element and preparation method and application of composite material

The invention discloses a composite material for an electric apparatus element. The composite material for the electric apparatus element comprises the following raw materials: conductive filler, polyphenylene sulfide, polyetherimide, polyphenylene sulfone and a copolymer, the throwing mass ratio of the polyphenylene sulfide, the polyetherimide and the polyphenylene sulfone is 1-5: 0.5-2: 1, and the monomer of the copolymer should comprise styrene and maleic anhydride, and further selectively comprise methacrylate and/or glycidyl methacrylate. The preparation method comprises the following steps: weighing the various raw materials according to a formula amount, drying a resin component in the raw materials and then mixing the resin component with the copolymer, and then blending, melting and extruding the copolymer and the rest raw materials, and cooling and dicing to obtain the final product. The invention further provides an electric apparatus element prepared from the composite material. The service temper
