Polyurethane steel wire rope core conveying belt and preparation method thereof

The invention relates to a polyurethane steel wire rope core conveyor belt and a preparation method thereof. Core rubber comprises the following components in parts by weight: 40-70 parts of mixed polyurethane rubber, 30-60 parts of natural rubber, 30-50 parts of reinforcing filler, 3-7 parts of an active agent, 5-9 parts of an anti-aging agent, 3-5 parts of maleic anhydride grafted ABS (Acrylonitrile Butadiene Styrene) resin, 3-6 parts of cobalt boroacylate, 4-8 parts of an anti-fatigue agent PL600 and 2.5-4.5 parts of a vulcanizing agent. The covering rubber comprises the following components in parts by weight: 40-80 parts of mixed polyurethane rubber, 20-60 parts of natural rubber, 30-60 parts of reinforcing filler, 6-10 parts of an active agent, 3-7 parts of an anti-aging agent, 3-8 parts of a plasticizer and 4-8 parts of a vulcanizing agent; the core rubber and the covering rubber are subjected to extrusion, cold pressing and vulcanization to obtain a finished product belt of the polyurethane steel wire
