The invention relates to a high-temperature-resistant anti-aging electric power insulation material. The high-temperature-resistant anti-aging electric power insulation material is prepared by adopting the following raw materials: 30 to 50 parts of EPDM, 12 to 20 parts of a plasticizing agent, 2 to 5 parts of chloroplatinic acid, 10 to 15 parts of rubber softening oil, 1 to 2 parts of a lubricating agent, 20 to 36 parts of ceramic powder, 15 to 25 parts of graphite powder, 8 to 18 parts of quartz sand, 2 to 20 parts of clay, 4 to 30 parts of magnesite, 42 to 50 parts of dolomite, 20 to 38 parts of lime powder, 5 to 20 parts of pine oil, 10 to 35 parts of silica gel, 12 to 20 parts of silicon nitride powder, 25 to 30 parts of glass fibers, 50 to 55 parts of polyvinyl chloride, 60 to 90 parts of polyvinyl alcohol, 40 to 45 parts of polycarbonate, 20 to 30 parts of sodium succinate, 32 to 45 parts of polydimethylsiloxane and 15 to 50 parts of hydroxyethyl cellulose. The length of the glass fiber is preferably 3 to 5 mm, the pore volume of the silica gel is 0.4 to 0.5 ml/g, and the average bore diameter is 3 to 4 nm.
