Dustproof coating for car fender and preparation method of dustproof coating

Abstract

The invention discloses a dustproof coating for a car fender. The dustproof coating is prepared from the following raw materials: polyurethane resin, pure acrylic emulsion, organic silicon modified polyester resin, ethylene resin, sodium carbonate, a leveling agent, a catalyst, a synergist, mica powder, titanium dioxide, methyl isobutyl ketone, dimethyl carbonate, deionized water and rosin modified resin. The preparation method successively comprises the following steps: (1) uniformly stirring the raw materials; (2) preparing a mixed solution; (3) preparing a coating mixed solution; and (4) grinding the coating mixed solution, and filtering to obtain a finished product. The product is excellent in performance and good in dustproof performance; a coating layer has a flat, exquisite and smooth surface and good gloss retention, both the tensile strength and elongation rate at break are better than those of an ordinary coating, and the application requirements of the car fender on the corrosion resistance and weather resistance of the coating of a box body can be met; and the preparation method is simple, relatively low in cost and suitable for industrialized mass production.
