Problems solved by technology

[0003] Most of the water-based hydroxyacrylic dispersions currently on the market are acrylic resins obtained through solution polymerization, and then dispersed in water under the action of hydrophilic groups and salt-forming reactions. When doing solution polymerization, more or less 100# Solvent oil, propylene glycol butyl ether, diethylene glycol butyl ether, propylene glycol methyl ether acetate and other organic solvents, these organic solvents will volatilize in the air during the coating construction, causing certain pollution to the environment. Aiming at these defects, a design A kind of aqueous hydroxyacrylic acid dispersion and preparation method are very necessary

Abstract

The invention discloses a water-based hydroxy acrylic acid dispersion and a preparation method thereof. The formula comprises: by mass,15 to 25 parts of an acrylic acid polymerization monomer, 20 to 30 parts of an organic solvent, 15 to 25 parts of deionized water, 10 to 20 parts of a chain regulator, 2 to 4 parts of a cross-linking agent, 10 to 20 parts of an alkaline neutralizer and 1 to 3 partsof an initiator. The preparation method comprises the following steps: 1, raw material selection, 2, mixing and stirring, 3, solution preparation, 4, alkaline neutralization, 5, dispersion preparation, and 6, encasement and storage. The dispersion is safe and reliable, does not contain a solvent, utilizes hydroxyl radical polymerization, and has the advantages of high glossiness, good weather resistance, high hardness, good water resistance, good chemical resistance and the like. The preparation method is simple and rigorous in process, cheap in raw materials, low in cost and convenient to process.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based hydroxyacrylic acid dispersion and a preparation method. Background technique [0002] Waterborne hydroxyacrylic dispersions have been greatly developed in recent years, and their status in the field of industrial coatings has become more and more important. Since the hydroxyl and isocyanate curing agents in waterborne hydroxyacrylic dispersions can be cross-linked and cured, the waterborne two-component After the coating is formed into a film, it has the advantages of high gloss, high hardness, good weather resistance, good scratch resistance, good acid and alkali resistance, so it is widely used in wood paint, metal paint, plastic paint, glass paint and other industries. [0003] Most of the water-based hydroxyacrylic dispersions currently on the market are acrylic resins obtained through solution polymerization, and then dispersed in water under the action of hy...
