Abstract

The invention discloses a waterborne double-component full-light opalescent finish paint and a preparation method thereof and belongs to the field of paint. The waterborne double-component full-light opalescent 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: 50-60 parts of polyacrylic polyols, 0.1-0.5 part of flatting agents, 20-25 parts of semi-finished product white slurry, 20-40 parts of semi-finished product colored slurry, 1.0-5.0 parts of pearlescentparticles, 0.1-0.5 part of de-foaming agents, 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 full-light opalescent finish 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 belongs to the field of coatings, and in particular relates to a water-based two-component full-gloss pearl finish paint and a preparation method thereof. Background technique [0002] There are many kinds of coatings on the market, mainly divided into organic coatings and inorganic coatings, and organic coatings are divided into organic solvent-based coatings and organic water-based coatings according to the different solvents used. Due to the high VOC, organic solvent-based coatings cannot meet people's increasing requirements for environmental protection. [0003] Organic water-based paints, that is, water-based paints, are increasingly becoming a research hotspot. Water-based wood paints with acrylic acid as the main component are characterized by good adhesion and will not deepen the color of wood, but poor wear resistance and chemical resistance. The hardness of the film is relatively soft, the pencil test is HB, the fullness is po...
