Abstract

Anti-abrasion waterborne polyurethane composite paint is prepared from, by weight, 45-65 parts of waterborne polyurethane, 25-45 parts of deionized water, 20-30 parts of polyacrylic acid, 15-25 parts of polyisocyanate, 15-25 parts of acrylate, 10-20 parts of a curing agent, 10-15 parts of titanium dioxide and 3-8 parts of a defoaming agent. The anti-abrasion waterborne polyurethane composite paint combines advantages of polyurethane paint and polypropylene paint and can be fixed fast to form a film, and a coating has excellent adhesive force, is free of pollution and has the advantages of being resistant to abrasion, corrosion, heat, light and water and good in mechanical property.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a wear-resistant water-based polyurethane composite coating. Background technique [0002] Coating refers to the general term for materials that can form a tough protective film when applied to the surface of an object. It is a viscous liquid that is coated on the surface of an object to be protected or decorated and can form a continuous film firmly attached to the object to be coated. Protection, decoration, or insulation, anti-mildew, anti-rust, etc. The general composition of coatings includes film-forming substances, pigments, fillers, solvents, and additives. [0003] Water-based coatings refer to coatings that use water as a solvent or dispersion medium, including water-soluble coatings, water-dilutable coatings and water-dispersible coatings. It is non-combustible and non-polluting. The disadvantage of water-soluble paint is that it is easy to age, the elongation rate decreases...
