Wear-resistant polyurethane layer for wheels for forklift trucks

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a wear-resistant polyurethane layer for a fork wheel. Background technique [0002] The current forklift wheel mainly includes a wheel core and a polyurethane layer, and the polyurethane layer is set outside the wheel core; during the operation of the forklift, the polyurethane layer and the ground produce relative sliding friction, and the contact surface is severely worn, which causes the forklift wheel to run unstable and cannot be used normally. , thus affecting the service life of the fork wheel, after partial damage, it is necessary to replace the whole, increasing the cost of use. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a wear-resistant polyurethane layer for forklift wheels, which has an excellent toughening effect, greatly improves the wear resistance and aging resista...
