Abstract

The invention discloses a water-based environment-friendly paint. The water-based environment-friendly paint is characterized by being prepared from the following raw materials by weight: 40-50 partsof hyperbranched urethane acrylate, 4-8 parts of acrylonitrile-based cross-linked polymer hollow microspheres, 3-5 parts of allyl chloro(difluoro)acetate ionized N, N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid, 1-3 parts of 2, 2-dimethylethenylboronic acid pinacol ester, 1-3 parts of N, N'-(1, 2-dihydroxyethylene)diacrylamide, 0.3-0.6 part of a photoinitiator, 10-15 parts of filler, 1-3 partsof a dispersing agent, 0.5-1.5 parts of a defoaming agent and 25-35 parts of water. The invention also discloses a preparation method of the water-based environment-friendly paint. The water-based environment-friendly paint disclosed by the invention has the characteristics of good comprehensive performance, large adhesive force to a base material, excellent storage and transportation stability, excellent corrosion resistance, flame retardance and high temperature resistance, fast drying and curing speed, convenient construction, large coating hardness, good toughness and weather resistance, and long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based environmental protection coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of industry, the problem of environmental pollution has attracted more and more attention. Countries around the world are taking strict measures to limit the emission of volatile organic compounds. Green materials have become the mainstream in the field of material research and application. In order to adapt to this trend, water-based coatings emerged as the times require and have become an extremely active research and development field. It is the development trend of the coatings industry at present and even in the future. It will definitely become the "new darling" of the coatings market and has a large market. potential. [0003] Water-based coatings use water as the dispersion medium and diluent. Different from tradition...
