High-hardness and high-fullness special coating for wheels, and preparation method thereof

Abstract

The invention relates to a water-based special coating for wheels, and especially relates to a high-hardness and high-fullness special coating for wheels, and a preparation method thereof. The coatingcomprises water-based resin, a conventional aid, a water-based modified polyurethane dispersant, a neutralizer, water-based aluminum silver powder, water-based amino resin, deionized water, wax emulsion and a cosolvent. The preparation method comprises the following steps: preparing an aluminum paste, preparing a slurry, slowly adding the aluminum paste into the slurry, and dispersing to obtain the finished product. The special coating for wheels is applied to the surfaces of the wheels, the obtained appearance effect is similar to the appearance effect of oily wheel amino baking varnish, theusing effect of the oily wheel amino baking varnish is achieved, good stability and water resistance are achieved, meanwhile, the hardness is high, the fullness is high, good construction performanceis achieved, the preparation method is simple, and the production cost is reduced.

Description

technical field [0001] The invention relates to a special paint for water-based wheels, in particular to a special paint for wheels with high hardness and fullness and a preparation method thereof. Background technique [0002] Water-based amino baking varnishes for wheels are subject to differences in performance. At present, the market is still dominated by oil-based baking varnishes. Oil-based baking varnishes use organic solvents as solvents, which contain a large amount of irritating gases such as formaldehyde, toluene, and xylene, as well as sodium nitrite and chromium. Salt and other internationally recognized carcinogens; as people's awareness of environmental protection continues to strengthen, domestic and foreign requirements for irritating gases such as formaldehyde, toluene, and xylene in coatings are becoming more and more stringent. With the development of water-based technology With continuous maturity and continuous strengthening of environmental protection ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical defects such as low hardness, poor fullness, poor workability, poor stability, and poor water resistance of the existing water-based amino baking paint for wheels, the present invention provides a special coating for wheels with high hardness and high fullness and a preparation method thereof. The special coating for wheels not only has high hardness, high fullness, high stability, good water resistance, coating film hardness can reach 4H, excellent flexibility, but also has good construction performance. The preparation method is simple and the production cost is reduced.
