Water-based glass paint containing modified diatomite and preparation method thereof

Abstract

The invention discloses water-based glass paint containing modified diatomite and a preparation method thereof. The water-based glass paint comprises the following raw materials in parts by weight: 55-65 of acrylate emulsion, 8-10 of water-based amino resin, 1-3 of dipropylene glycol mono butyl ether, 10-15 of pure water, 0.4-0.6 of fatty acid polyglycol ester, 0.2-0.4 of a defoaming agent, namely polyoxypropylene glycerol ether, 0.2-0.6 of dioctyl sodium sulfosuccinate, 0.3-0.5 of zinc oxide, 0.2-0.4 of adhesion promoter BOK-M-208, 0.3-0.5 of flatting agent L-350, 0.3-0.5 of modified diatomite, 0.3-0.1 of fumed silica and 0.8-1.2 of water-based silicone coupling agent A800. The water-based glass paint produced by the invention has no bubbles, no agglomerates, no foreign matters and recipitation stratification, can be infinitely diluted with water and reduce the cost and is environment-friendly; a paint film has very strong cohesion and adhesive force as well as high strong abrasive resistance at a room temperature; the added modified diatomite and fumed silica serve as thickening agents so that the adhesive force of the paint film is enhanced; and the added water-based silane coupling agent further enhances the adhesive force of the paint film.

Description

technical field [0001] The invention mainly relates to a paint and a preparation method thereof, in particular to a water-based glass paint containing modified diatomite and a preparation method thereof. Background technique [0002] As a functional and environmentally friendly water-based paint, water-based glass paint has the advantages of obvious decorative effect, colorful paint film, and easy cleaning. Water-based glass paint has poor solvent permeability, poor wettability of water-based paint to glass, and high surface finish of the substrate, which makes it difficult for water-based paint to adhere well to glass equipment, which seriously hinders the development of glass paint. The types of water-based glass paint mainly include polyurethane water dispersion system, water-soluble polyacrylic resin type, and acrylate-modified polyurethane type. The main problems are poor adhesion, poor chemical resistance, poor solvent resistance, and poor water boiling resistance. C...
