Abstract

The invention discloses a poly-heterocyclic ring based acrylate monomer modified waterborne hydroxy acrylic dispersion and a preparation method thereof. The dispersion comprises, by weight, 20-50 parts of solvents, 5-10 parts of poly-heterocyclic ring based acrylate monomers, 50-70 parts of acrylic alkyl ester, 25-30 parts of acrylic functional monomers, 1-3 parts of chain transfer agents, 2-4 parts of initiators, 1-3 parts of anion exchange reactive emulsifiers, 2-4 parts of initiators, 100-120 parts of deionized water, 0.1-0.5 part of defoaming agents, 0.2-0.6 part of leveling agents and 0.3-0.8 part of wetting agents. The glossiness of a film is higher than 97 degrees, the hardness of the film reaches up to 2H, the film is strong in impact resistance, excellent in flexibility and adhesive force, and the dispersion has prominent chemical corrosion resistance such as acid resistance, alkali resistance and water resistance, meets natural zero-VOC (volatile organic compounds) paint standards, is environmentally friendly, non-toxic and free from pollution and can be used for waterborne wood paint, waterborne industrial paint and waterborne floor paint.

Description

technical field

[0001] The invention relates to a water-based paint, in particular to a water-based hydroxyacrylic acid dispersion modified by a polyheterocyclic acrylate monomer and a preparation method thereof. Background technique

[0002] With the increasingly stringent control of VOC emissions in coatings, the use of solvent-based coatings has been restricted unprecedentedly. People have attached great importance to VOC-free or low-VOC environmentally friendly coatings, and high-performance, aldehyde-free and cross-linked water-based coatings have been developed rapidly. Water-based coatings have the advantages of non-flammability, less environmental pollution, and low harm. With the establishment of environmental protection regulations and the enhancement of people's awareness of environmental protection, water-based coatings have received extensive attention and are an inevitable trend in the development of the coatings industry.
