Abstract

The invention relates to the technical field of coatings, and specifically discloses water varnish and a preparation method thereof. The water varnish is prepared from an aqueous acrylic hydroxyl functional group copolymer emulsion, an aqueous acrylic polyester modified functional group copolymer emulsion, crosslinked resin, a substrate moistening agent, benzoin, a defoaming agent, a light stabilizer, an ultraviolet light absorbent, a dispersing agent and the balance of deionized water. The water varnish disclosed by the invention has the advantages of good stone impact resistance, good gasoline resistance, high paint film hardness, strong adhesion, strong corrosion resistance, high transparency and good attractiveness.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based varnish and a preparation method thereof. Background technique [0002] With the rapid development of China's economy in recent years, people's requirements for material quality have also been continuously improved. Water-based varnishes have strong adhesion and anti-oxidation and anti-corrosion capabilities to metals and coatings. After curing, they will form transparent and bright coatings on the surface. , Abrasion-resistant, tough and strong acid-alkali-resistant protective film, with anti-fingerprint, temperature, moisture, acid, and alkali properties, is the best choice for anti-corrosion and anti-discoloration of the coating surface. However, water-based varnishes generally have high viscosity, and the thickness of the coating is difficult to control. After dilution, other properties of the paint film will be affected, and the gloss and transparency of the p...
