Anti-aging flame-retardant ethylene propylene rubber insulating material

The invention discloses an anti-aging flame-retardant ethylene propylene rubber insulating material. The insulating material comprises the following components in parts by weight: 90-100 parts of ethylene propylene diene monomer, 10-15 parts of white carbon black, 35-40 parts of talcum powder, 3-4 parts of semi-refined paraffin, 1-1.5 parts of stearic acid, 1-1.5 parts of an accelerant DM, 0.5-1 part of an anti-aging agent RD, 1.5-2 parts of an anti-aging agent MB, 0.5-1 part of an anti-aging agent DNP, 8-10 parts of zinc oxide, 3-4 parts of 65 # cylinder oil, 70-80 parts of aluminum hydroxide and 4.5-5.5 parts of a vulcanizing agent DCP. The preparation process is simple, and the prepared insulating material is high in aging resistance and flame retardance, has excellent electrical insulation performance, wear resistance, aging resistance, chemical corrosion resistance and impact resistance, and is suitable for preparing rubber sleeve cables for coal mines and electric wires and cables for high-end equipment
