Abstract

The invention belongs to the technical field of coatings, and particularly relates to a waterborne primer topcoat syncretic coating and a preparation method thereof. The waterborne primer topcoat syncretic coating is prepared from the following components in parts by weight: 10-20 parts of waterborne epoxy modified acrylic resin, 15-20 parts of alcohol ether cosolvent, 0.1-1 part of an amine neutralizer, 3-7 parts of sodium silicate, 0.1-2 parts of a base material wetting agent, 0.3-2 parts of a dispersing agent, 1-3 parts of a water-based defoaming agent, 5-18 parts of anti-rust pigment, 15-30 parts of pigments and fillers, 0.1-1 part of a drier and 0.1-1 part of an ultraviolet light absorber. The waterborne primer topcoat syncretic coating has the advantages of being excellent in variousperformances, high in adhesive force, free of volatile organic matter, healthy, environmentally friendly and good in water resistance, weather resistance and corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based bottom-surface-in-one paint and a preparation method thereof. Background technique [0002] At present, my country's industrial coatings are still mainly solvent-based, and a large number of volatile organic compounds (VOCs) have caused serious pollution to the ecological environment during the coating process, and have also brought great harm to human health. With the improvement of people's awareness of environmental protection, governments of various countries have introduced a large number of relevant regulations to limit the emission of VOCs. In order to keep up with the development of the times, industrial coatings are changing to be environmentally friendly. Environmentally friendly coatings include water-based coatings, powder coatings, UV-curable coatings and high-solid coatings, and water-based coatings are the fastest growing category. [00...
