Abstract
The invention discloses waterborne double-component metallic flashy finish paint and a preparation method thereof and belongs to the field of paint. The waterborne double-component metallic flashy finish paint comprises a component A and an anionic modified HDI (Hexamethylene Diisocyanate) polyisocyanate, wherein the component A comprises the following materials in part by weight: 70-80 parts of polyacrylic polyols, 0.1-0.5 part of flatting agents, 0.1-0.5 part of pH regulators, 0.1-0.5 part of de-foaming agents, 1.0-5.0 parts of silver powder, 0.1-2.0 parts of film-forming auxiliaries and 1.0-5.0 parts of water. The weight ratio of the component A to the anionic modified HDI polyisocyanate is 1:(0.2-0.3). The waterborne double-component metallic paint has excellent glossiness and appearance, is excellent in stain resistance and chemical property, never becomes yellow, is rust-proof and high-temperature resistant, and can be simultaneously applied together with other paint, such as emulsion paint.
Description
Technical field [0001] The invention is the field of coating, which involves a water -based dual -component metal flashing tacor paint and its preparation methods. Background technique [0002] There are many types of coatings on the market. They are mainly divided into organic coatings and inorganic coatings. Organic coatings are divided into organic solvent -based coatings and organic water -based coatings according to different solvents.Because of the high VOC, organic solvent -based coatings cannot meet people's increasing requirements for environmental protection. [0003] Organic water -based coatings, that is, water -based coatings, are now increasingly becoming a hot spot in research.Conventional water -based paint is poorly wettic, and it is often not good to reflected with other water properties. It is easy to destroy emulsion under high -speed stirring. Invention content [0004] The technical problem to be solved by the present invention is that the existing technolo...
