Abstract
The invention discloses a polyurethanecoating layer for a fork truck wheel hub. Raw materials of the polyurethanecoating layer comprise, by weight, 130-140 parts of a main material, 1-3 parts of sulfur, 0.5-1.2 parts of dibenzoyl peroxide, 1-2 parts of dibenzothiazyl disulfide, 1-2 parts of zinc diethyl dithiocarbamaate, 45-55 parts of a filler, 1-2 parts of carboxyl-terminated silicone oil, 1-2parts of an anti-scorching agent, 1-2 parts of an antioxidant, 1-2 parts of a plasticizer and 1-2 parts of a softener. The polyurethanecoating for the fork truck wheel hub has the advantages of excellent wear resistance, suitableness for being continuously used under high wear conditions, high adhesion strength with a wheel hub, no sliding friction, high tensile strength, good fire resistance and good corrosion resistance.
Description
Technical field [0001] The invention relates to the technical field of polyurethane, in particular to a polyurethane coating layer for the wheel core of a fork wheel. Background technique [0002] At present, the use of forklifts is relatively common, and the wheel is an important part of the forklift. Generally, the surface of the wheel core is coated with a polyurethane coating. As an important part of the wheel, the polyurethane coating is firm and stable. Particularly important. However, the polyurethane coatings on the market have reduced firmness due to wear after a period of use, which poses certain safety risks. Summary of the invention [0003] Based on the technical problems existing in the background art, the present invention proposes a polyurethane coating for the wheel core of a fork wheel, which has excellent wear resistance and is suitable for continuous use under high wear conditions and adheres to the wheel core. High strength, not easy to produce sliding frict...
