Water-soluble anticracking latex paint

Abstract

Disclosed water-soluble anticracking latex paint is prepared from the following raw materials in parts by weight: 4-8 parts of silicon carbide, 10-15 parts of ultrafine silicon dioxide, 7-14 parts of borax, 80-120 parts of water, 3-7 parts of acrylic acid, 6-9 parts of sodium dodecyl sulfate, 2-6 parts of potassium persulphate, 3-7 parts of hydroxyethyl cellulose with the specification of 0.3 million unit, 5-9 parts of titanium dioxide, 3-6 parts of kaolin, 10-20 parts of light calcium powder, 15-25 parts of heavy calcium powder, 4-6 parts of a silane coupling agent, 7-10 parts of propylene glycol, 20-40 parts of an acrylate emulsion and parts of thickening agent ASE604-8. The provided water-soluble anticracking latex paint is capable of forming a paint film which is flat, bright, strong durability, rapid in drying speed, firm in adhesion, stable in color and resistant to explosion and crack.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a water-soluble anti-crack latex paint. Background technique [0002] Before the construction of latex paint, the wall surface must be well treated. First use the back cover to seal the wall surface, and then use water-resistant putty; when using latex paint, it should be stirred evenly. Due to the precipitation of the color paste after long-term storage, the construction at this time will cause the finish to bloom, which will seriously affect the decorative effect; the viscosity of the latex paint should be adjusted during construction, and the methods of brushing, roller coating and spraying should be used, but no matter which The methods are all suitable for easy brushing during construction and no obvious brush marks after brushing. [0003] In the past, paints mainly used organic solvents toluene, xylene, and solvent naphtha as solvents for paints. These organic s...

[0002] Before the construction of latex paint, the wall surface must be well treated. First use the back cover to seal the wall surface, and then use water-resistant putty; when using latex paint, it should be stirred evenly. Due to the precipitation of the color paste after long-term storage, the construction at this time will cause the finish to bloom, which will seriously affect the decorative effect; the viscosity of the latex paint should be adjusted during construction, and the methods of brushing, roller coating and spraying should be used, but no matter which The method is easy to paint during construction, and it is better to have no obvious brush marks after brushing

[0003] In the past, paints mainly used organic solvents toluene, xylene, and solvent naphtha as solvents for paints. These organic solvents volatilized in large quantities into the air during the film-forming process of paints. The air was destroyed, the environment was polluted, and it caused harm to the human body.
