Abstract
The invention relates to a high-strength reclaimed rubber core rubber for common wire rope conveyer belts, and belongs to the technical filed of conveyer belts. The high-strength reclaimed rubber core rubber comprises a rubber system, a reinforcing system, a tackifying system, an anti-ageing system and a vulcanizing system, and the high-strength reclaimed rubber core rubber for common wire rope conveyer belts is obtained through first-stage mixing, second-stage mixing, molding and vulcanization. The high-strength reclaimed rubber is used in the wire rope conveyer belt core rubber, so the cost of routine wire rope conveyer belt core rubber is reduced by 20-40%; and only butadiene-styrene rubber is usually used in routine wire rope conveyer belt core rubber systems, so the use field of the high-strength reclaimed rubber is widened.
