Abstract

The invention discloses a valve hand wheel coating, and relates to the technical field of valve manufacturing. The valve hand wheel coating is prepared from, by weight, 70-80 parts of high chlorinated polyethylene resin, 40-50 parts of bisphenol A epoxy resin, 15-20 parts of gypsum powder, 13-17 parts of expansive cement, 11-15 parts of hydroxypropyl starch ether, 9-13 parts of jute fibers, 7-10 parts of nano aluminum oxide, 5-8 parts of rice bran wax, 5-8 parts of sorbitol, 4-6 parts of polyoxyethylene polyoxypropylene ether, 3-5 parts of cobaltous hydroxide, 15-20 parts of ethyl acetoacetate, 35-45 parts of glycerin and 50-60 parts of water. The coating can be firmly attached to a hand wheel, the compact and hard coating can be quickly formed after spraying, the coating layer has excellent abrasive resistance, weather resistance, corrosion resistance, ageing resistance and the like, and therefore the hand wheel can be controlled conveniently and the service life of the hand wheel can be prolonged.

Description

Technical field: [0001] The invention relates to the technical field of valve manufacturing, in particular to a valve handwheel paint. Background technique: [0002] The valve is a control component in the fluid delivery system, which has the functions of cutting off, regulating, diverting, preventing reverse flow, stabilizing pressure, shunting or overflowing, etc. The current valve handwheel is generally disc-shaped, and the disc-shaped handwheel is easy to slip, and will wear after long-term use; , prone to corrosion, which affects the normal use and service life of the handwheel. In order to solve the above problems, a layer of paint is usually sprayed on the handwheel to increase the friction between the operator's hand and the handwheel, and the coating has good wear resistance, weather resistance, corrosion resistance and anti-aging properties. Invention content: [0003] The technical problem to be solved by the present invention is to provide a valve handwheel ...
