Abstract

The invention discloses a high-solid varnish type oily acrylic resin for automobiles and a preparation method thereof, which belongs to the field of automobile coatings and solves the problems of low solid content, high viscosity and poor solubility in existing acrylic resin coatings. The resin of the present invention contains components acrylic acid, styrene, butyl acrylate, hydroxyethyl methacrylate, methyl methacrylate, methacrylic acid, butyl methacrylate, isooctyl acrylate, n-dodecyl mercaptan, Lauryl methacrylate, isobornyl methacrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, No. 100 mineral spirits, di-tert-amyl peroxide, glycidyl tert-carbonate and resin active diluent, the solid content can be Up to 90%, good dilution, low viscosity, self-made reactive diluent can greatly improve the water resistance and acid resistance of the coating, the construction solid content of the resin is nearly 70%, greatly reducing VOC emissions, environmentally 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...
