Abstract

The invention discloses an environment-friendly coating for a steel ring wheel. The environment-friendly coating is prepared from the following components: a polyurethane emulsion, butyl acetate, vinyl silicone oil, nanometer titania, attapulgite, mica powder, acetylcholine, water, aluminum borate whisker, menthyl acetate, vegetable gelatin, a plant extract and a coalescing agent. After the coating is formed into a film, the film is high in hardness, good in abrasion resistance, short in hard drying time, good in abrasion resistance and fracture resistance, excellent in abrasion resistance and good in adhesive force. The prepared coating is good in stability, has better stability after being used for a long time, and is low in possibility of cracking, and fine cracks are low in possibility of expanding and better in repairability, so that the intrinsic strength and the stability of the coating are greatly improved, and the life span is greatly prolonged. According to the coating, through synergetic cooperation function of the components, the life span of the coating film formed by the coating is greatly prolonged, and is increased by 400% as compared with that of the coating film formed by the common polyurethane emulsion coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a green and environment-friendly coating for steel rim wheels. Background technique [0002] The steel rim wheel is the hub, which is a barrel-shaped, center-mounted metal part on the shaft that supports the tire. In addition to good surface quality and workability, coatings for automobile steel rims and wheels also need different requirements according to different application fields. The rim wheel requires that the coating film should have excellent salt spray resistance and weather resistance. The film-forming aids and propylene glycol in traditional paints contain a certain amount of volatile organic compounds, which are harmful to the environment and human health; under the influence of long-term outdoor sunlight and other natural climates, paints often fall off and affect Problems with paint effects. Contents of the invention [0003] The object of the present inventi...
