FIELD: transportation.
SUBSTANCE: conveyor belt consists of a carrying covering layer, an interply rubber layer located directly below the carrying covering layer, a strengthening layer, including steel cords embedded in polychloroprene and located directly below the interply rubber layer, and a traction covering layer located directly below the strengthening layer. The interply rubber layer is a mixture that consists of 40 to 90 phr of polyvinyl chloride and from 10 to 60 phr of acrylonitrile rubber. The traction covering layer consists of a rubber polymer. The carrier coating layer consists of a urethane rubber based on polyethers, capable of milling, which includes places for forming a transverse bond.
EFFECT: increasing the belt resistance to surface abrasion is increased.
