The invention discloses a wear-resistant polyurethane layer for wheels for forklift trucks. The wear-resistant polyurethane layer comprises, by weight, 90-110 parts of polybutylene glyool adipate, 15-25 parts of diphenylmethane-4, 4'-diisocyanate, 10-14 parts of polyoxypropylene triol, 10-12 parts of glycerol, 3-5 parts of zinc naphthenate, 10-16 parts of butylene glycol, 10-16 parts of heavy calcium carbonate, 15-25 parts of rectorite powder, 6-14 parts of melamine resin granules, 1-2 parts of surfactants, 3-5 parts of vulcanization accelerators, 5-7 parts of foaming agents, 2-4 parts of moldrelease agents and 1-2 parts of toner. The wear-resistant polyurethane layer has the advantages that excellent toughening effects can be realized by the wear-resistant polyurethane layer, the wear resistance and the ageing resistance of the wheels for the forklift trucks can be greatly improved by the wear-resistant polyurethane layer, the bearing capacity of the wear-resistant polyurethane layerfor the wheels for the forklift trucks can be improved, and the wear-resistant polyurethane layer is excellent in bearing capacity and long in service life.
