Abstract

The invention discloses an automobile waterborne metallic flashing coating and a preparation method thereof. The automobile waterborne metallic flashing coating comprises the following components in parts by mass: 4-8 parts of dihydromethyl propionic acid, 3-7 parts of ethyl acrylate, 5-10 parts of metacrylic acid ester, 2-6 parts of crylic acid glycidyl ether, 1-3 parts of butylexyl ester, 1.5-5.5 parts of lauryl mercaptan, 6-9 parts of triethylamine, 0.1-0.6 part of polyepoxysuccinic acid, 2-4 parts of triethanolamine, 3-6 parts of waterborne aluminum powder, 0.2-0.8 part of acetate butyrate carboxymethyl cellulose, 1-2 parts of nano titanium dioxide, 0.2-0.8 part of a defoaming agent, 1-3 parts of a dispersing agent, 0.4-0.8 part of a stabilizing agent and 30-50 parts of water. The automobile waterborne metallic flashing coating is good in flashing property, high in glossiness, good in impact resistance, high in hardness, simple in preparation method and convenient to spray.

Description

technical field [0001] The invention belongs to the technical field of automobile coatings, in particular to a water-based metallic flash coating for automobiles and a preparation method thereof. Background technique [0002] Automotive topcoat is a coating applied on the exterior of the car to provide exterior decoration. It must be able to maintain surface gloss and color retention for a long time, and have properties such as oxidation resistance, hydrolysis resistance, acid rain resistance, and weather resistance. 50% of the system. Traditionally, natural color topcoats are used for automotive topcoats, but in the past two decades, more and more metal flash basecoats and finish coatings have been used as a supporting system, because of its bright and dynamic metallic color, The unpredictable corner-following effect is deeply loved by the market. At present, more than half of the cars have adopted metallic flash paint. Colorful colors are an important part of car decor...
