Abstract

The invention discloses weather-resistant anti-abrasion modified polyurethane waterborne paint. The waterborne paint is prepared from, by weight, 80-120 parts of modified polyurethane, 10-30 parts of polyacrylate emulsion, 5-15 parts of dioctyl phthalate, 2-8 parts of tributyl phosphate, 1-5 parts of glycerin alkyd resin, 3-9 parts of 3-aminopropyltrimethoxysilane, 1-5 parts of ethylene glycol butyl ether, 2-6 parts of hydroxymethyl cellulose, 1-5 parts of titanium dioxide, 2-4 parts of talcum powder, 1-5 parts of silicon dioxide, 2-4 parts of zinc oxide, 4-6 parts of aluminium oleate, 5-9 parts of pigments, 2-5 parts of flexibilizers, 1-6 parts of defoaming agents, 3-5 parts of flatting agents, 4-8 parts of mildew preventives, 3-8 parts of dispersing agents and 15-25 parts of deionized water. The invention further discloses a method for preparing the weather-resistant anti-abrasion modified polyurethane waterborne paint. The obtained waterborne paint has good weather resistance and abrasion resistance, has excellent water resistance, heat stability and adhesion between coated objects on the basis that a raw material is good in softness, chemical resistance and environment-friendly performance, and is excellent in comprehensive performance, good in durability and wide in application prospect.

Description

technical field [0001] The invention relates to water-based coatings, in particular to a weather-resistant and wear-resistant modified polyurethane water-based coating. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based coatings include water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. [0003] The polyurethane water-based coatings in the prior art have single functions, poor weather resistance and wear resistance, weak adhesion, and poor waterproof effect, which cannot meet the needs of actual use. Contents of the invention [0004] In order to solve the technical problems in the background technol...
