Abstract

The invention belongs to the technical field of automobile coating and specially relates to water-based high temperature plain colored paint capable of being used for a wet-on-wet middle-coating-freesystem and a preparation method thereof. The water-based high temperature plain colored paint capable of being used for the wet-on-wet middle-coating-free system includes an A component and a B component, wherein the A component includes aqueous acrylic acid polyol dispersion, aqueous polyurethane dispersion, ultrafine talc powder, ultrafine barium sulfate, aluminum triphosphate, titanium dioxide,carbon black, an aqueous dispersant, methylated amino resin and pure water; and the B component includes the aqueous acrylic acid polyol dispersion, the aqueous polyurethane dispersion, an amine neutralizer, ethylene glycol butyl ether, titanium dioxide, a dispersant, methylated amino resin, a thickening agent and pure water. The water-based high temperature plain colored paint capable of being used for the wet-on-wet middle-coating-free system has excellent properties, strong paint film adhesion, high paint film hardness, and good water resistance, acid resistance, alkali resistance, weatherresistance and stone-chipping resistance, and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of automobile coatings, and in particular relates to a water-based high-temperature plain paint which can be used in wet-on-wet intermediate coating-free systems and a preparation method thereof. Background technique [0002] In recent years, energy saving and environmental protection have become the theme of world development. Automobile manufacturers all over the world have invested a lot of money in research in this area, continuously improving process equipment and improving process level. Automobile painting is one of the main processes of automobile manufacturing, and its energy consumption accounts for about 60% of the total energy consumption of the automobile manufacturing process.
