Abstract

The invention relates to the field of coating materials and particularly relates to PU paint. The PU paint is prepared from the following substances in parts by weight: 15-25 parts of castor-oil fatty acid, 15-20 parts of glycerine, 2-6 parts of benzoic acid, 35-45 parts of dilute solvent, 0.8-1.2 parts of catalyst hypophosphorous acid, 15-25 parts of glycidyl tertcarbonate, 10-15 parts of butyl acrylate, 5-10 parts of acrylic acid, 5-15 parts of 2-hydroxypropyl acrylate, 2-8 parts of hydroxyethyl methacrylate, 9-15 parts of crude terephthalic acid, 5-15 parts of phthalic anhydride, 15-20 parts of methyl methacrylate, 5-10 parts of styrene, 0.1-0.3 part of chain transfer agent, 0.05-0.08 part of antioxidant, 3-8 parts of organosilicone auxiliaries, 0.8-1.2 parts of initiator, 5-10 parts of curing agent, 5-8 parts of diluent and 40-50 parts of solvent. According to the PU paint provided by the invention, a paint film is thick in hand feeling, the gloss is soft, the chromaticity is uniform, the impact strength is good, and the leveling property and chemical corrosion resistance are good.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a PU paint. Background technique [0002] Coating is an indispensable decorative material in modern life. PU coating is a kind of coating with a large amount and a wide range in modern coatings, endowing the role of decoration and protection. PU paint is the collective name of all polyurethane coatings. Its film-forming method is natural film-forming without special process. It is chemically dry, operated according to the ratio, and has good comprehensive performance; good hardness, good fullness, good adhesion and good durability. ,Feel good. The paint film is thin and not very hard; but its adhesion is particularly good, its gloss is uniform, it does not look very bright, and it can well show the texture and color of the floor. There is a certain period of use after it is prepared. PU paint is currently widely used in industry and construction, so the technology is mature, there are ...
