High-voltage wear resistant rubber insulation material and preparation method thereof

Abstract

The invention discloses a high-voltage wear resistant rubber insulation material and a preparation method thereof. The high-voltage wear resistant rubber insulation material comprises, by weight, 50 parts of ethylene-propylene-diene monomer, 30 parts of butadiene rubber, 20 parts of chlorinated polyethylene rubber, 40 parts of furnace black, 30 parts of calcined potter's clay, 5 parts of a silane coupling agent, 2 parts of zinc stearate, 15 parts of rubber process oil P-150, 3 parts of an antioxidant N-phenyl-N'-isopropyl-p-phenylenediamine, 3 parts of sulfur, 5 parts of dicumyl peroxide, 3 parts of a vulcanization accelerant 2,2'-dithiodibenzothiazole, 5 parts of a vulcanization accelerant zinc oxide andstearic acid mixture, 15 parts of a fire retardant decabromodiphenylethane and 0.5 parts of an antioxidant 1010. The preparation method has the advantages of simplicity, flexible technology and reasonable formula design, and he prepared high-voltage wear resistant rubber insulation material has excellent mechanical performances and an excellent electric insulation performance, has a breakdown field intensity of 42kV/mm, is difficult to breakdown in a high voltage occasion, has an excellent wear resistance, and has a DIN abrasion of 100mm<3> or less, so the service life of the insulation material is effectively prolonged.
