Problems solved by technology

[0005] However, the process of flattening during construction can easily cause cracks in the paint layer, which seriously affects the decorative effect of relief paint.
There are two main reasons for the cracking of relief paint, namely, insufficient flexibility and too fast drying speed

Abstract

The invention discloses high-flexibility relievo paint. The high-flexibility relievo paint is prepared from the following raw materials in parts by weight: 150-200 g of deionized water, 60-70 g of a pure acrylic emulsion, 550-650 g of coarse whiting, 70-90 g of talcum powder, 30-40 g of a hydroxyethyl methyl cellulose water solution, 10-20 g of a lignocellulose water solution, 4-6 g of a film-forming additive, 1.5-2.5 g of an anti-corrosion disinfectant, 1.8-2.2 g of a dispersant, 1.8-2.2 g of a wetting agent, 3.5-4.5 g of a thickening agent and 9-11 g of ethylene glycol, wherein the hydroxyethyl methyl cellulose water solution is prepared by dissolving 2-4% hydroxyethyl methyl cellulose in water; the lignocellulose water solution is prepared by dissolving 1-3% lignocellulose in water. The invention further discloses a process for preparing a high-flexibility relievo paint. The relievo paint is low in drying speed, good in flexibility, free from cracking during construction and excellent in surface vision.

Description

technical field [0001] The invention relates to a synthetic resin water-soluble paint, in particular to a relief paint with high flexibility, and also relates to a preparation process of the relief paint with high flexibility. Background technique [0002] Water-soluble paint is a paint made of water-soluble synthetic resin as the main film-forming substance, water as the diluent, adding appropriate amount of pigments, fillers and additives, etc., and grinding. Water-based paint is also relative to oil-based paint. Oil-based paint is because the paint contains oil, and there is no oily substance in the composition of water-based paint. It uses water as a solvent and dispersion medium, so it is called water-based paint. . Most water-based paints contain no or very little harmful substances to the human body, so water-based paints are environmentally friendly and non-toxic. The rapid development of water-soluble coatings has formed a multi-variety, multi-functional, multi-pu...
