Abstract

The invention discloses an alcohol-resistant hydroxyl acrylic resin refinishing paint used for an automobile. Raw materials of the alcohol-resistant hydroxyl acrylic resin refinishing paint comprise, by weight, 100 parts of an alcohol-resistant hydroxyl acrylic resin, 3-5 parts of a dispersant, 1 part of nano titanium dioxide, 0-0.5 part of cyclohexanone, 2-2.5 parts of an epoxy curing agent and 20-25 parts of a solvent 1, wherein the alcohol-resistant hydroxyl acrylic resin comprises, by weight, 100 parts of methyl methacrylate, 8-20 parts of perfluoroalkylethyl acrylate monomers, 15 parts of hydroxyethyl acrylate, 25-35 parts of butyl acrylate, 3-7 parts of isobutyl methacrylate, 1.5-5 parts of an initiator and 50-70 parts of a solvent 2. The alcohol-resistant hydroxyl acrylic resin refinishing paint has good light protection and color protection properties, strong water-resistant and chemical-resistant properties, strong alcohol-resistant property and high corrosion-resistant capacity, can be dried rapidly, and is convenient for operation. The solvents are low in cost; and a preparation process is simple.

Description

technical field [0001] The invention relates to an automobile repair paint, in particular to an alcohol-resistant hydroxyl acrylic resin repair paint for automobiles. Background technique [0002] Acrylic resin does not undergo further cross-linking during the film-forming process, so its relative molecular weight is relatively large, it has good gloss and color retention, water and chemical resistance, fast drying, convenient construction, easy construction, recoating and rework, and the preparation of aluminum The whiteness and positioning of aluminum powder are good in powder coating. Thermoplastic acrylic resins are widely used in automobiles, electrical appliances, machinery, construction and other fields. However, the commonly used acrylic resin has high cost, poor alcohol resistance and low corrosion resistance, which limit the application occasions. However, the automotive refinish paint prepared with ordinary hydroxyacrylic resin has uneven blending and poor corro...
