Abstract

The invention relates to the field of water-based automotive coatings and discloses a yellowing resistant modified acrylic automotive coating. The automotive coating contains the following componentsin parts by weight: 35-45 parts of acrylic resin, 5-10 parts of epoxy resin, 3-5 parts of a hydroxypropyl cycloacrylate, methyl acrylate and lauryl acrylate copolymer, 1-3 parts of an anti-settling agent, 1-2 parts of a flatting agent, 1-2 parts of an antifoaming agent, 2-4 parts of a dry promoter, 0.1-0.5 part of barium sulfate and 20-30 parts of deionized water, wherein the hydroxypropyl cycloacrylate, methyl acrylate and lauryl acrylate copolymer is prepared from a solution polymer; and a weight ratio of the hydroxypropyl cycloacrylate to methyl acrylate to lauryl acrylate is 1:(1-2):(0.2-0.5). The invention aims to provide the yellowing resistant modified acrylic automotive coating with excellent advantages of fullness, glossiness, hardness, solvent resistance, weather resistance and resistance to discoloring and yellowing during high-temperature baking.

Description

technical field [0001] The invention relates to the field of water-based automotive coatings, in particular to an anti-yellowing modified acrylic automotive coating. Background technique [0002] Nowadays, coatings are used in many fields. Because they are often exposed to the atmosphere and are eroded by oxygen and moisture, it is easy to cause metal corrosion, wood decay, and cement weathering. With the improvement of people's living standards, the requirements for various aspects of coatings All have improved, especially the requirements for the hardness, wear resistance, fullness, impact resistance, aging resistance, anti-corrosion, waterproof, oil-proof, chemical resistance, light resistance, temperature resistance and other properties of the coating are increasing. The higher it is, so it is necessary to study more advanced coatings to meet people's needs. [0003] Currently on the market, most acrylic automotive coatings have problems such as poor weather resistance,...
