Chemical-corrosion-resistant insulating material and preparation method thereof

The invention relates to the technical field of production of insulating materials, and particularly relates to a chemical-corrosion-resistant insulating material and a preparation method thereof. Thematerial is prepared from the following raw materials in parts by mass: 50-65 parts of ethylene propylene diene monomer, 10-15 parts of metallocene linear low density polyethylene, 13-18 parts of fluororubber, 12-16 parts of compound insulating emulsion, 7.8-9.5 parts of a thermoplastic elastomer, 6-10 parts of coumarone resin, 2.5-3.2 parts of a flexibilizer, 6.5-8.8 parts of a filler, 5.8-7.2 parts of white carbon black, 2.2-2.8 parts of butylated hydroxytoluene and 1.8-2.6 parts of 2,2,6,6-tetramethylpiperidine. Compared with a chemically-corrosion-resistant insulating material provided inproportion, the chemically-corrosion-resistant insulating material prepared by the preparation method disclosed by the invention not only has better chemical corrosion resistance, but also has more excellent insulating proper
