Abstract

The invention discloses a high-solid-content finishing oil-based acrylic resin for automobiles and a preparation method thereof, which belong to the field of automobile paints and solve the problems of low solid content, high viscosity, poor solubility and the like in the existing acrylic resin paint. The resin contains acrylic acid, styrene, butyl acrylate, hydroxyethyl methacrylate, methyl methacrylate, methacrylic acid, butyl methacrylate, 2-ethylhexyl acrylate, n-dodecyl mercaptan, lauryl methacrylate, isoborneol methacrylate, 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, 100# solvent oil, di-tert-pentyl peroxide, glycidol tert-carboxylate and a resin reactive diluent. The solid content can reach 90%. The acrylic resin has the advantages of favorable dilution property and low viscosity. The self-made reactive diluent can greatly enhance the water resistance and acid resistance of the paint. The construction solid content of the resin is nearly 70%. The acrylic resin greatly lowers the discharge of VOC (volatile organic compound), and is environment-friendly and practical.

Description

technical field [0001] The invention belongs to the field of automobile coatings, and more specifically relates to a high-solid varnish type oily acrylic resin for automobiles and a preparation method thereof. Background technique [0002] As countries around the world pay more and more attention to the pollution of organic volatiles to the atmosphere and the protection of the environment, some industrialized countries have established special management agencies to formulate various laws and regulations to impose strict restrictions on the amount of solvent volatilization during coating construction. Therefore, various low-pollution coatings have emerged at the historic moment since the 1970s, and one type of coating with better effect and promising development is high-solid coating. High-solid acrylic paint, as a kind of high-solid paint, has attracted more and more people's attention because of its light color, color retention, gloss retention and other characteristics in...
