Preparation method of internal wall water-based latex paint capable of purifying air

Abstract

The invention discloses a preparation method of internal wall water-based latex paint capable of purifying air and belongs to the field of latex paint. The preparation method comprises the following steps: carrying out ball milling on talcum powder, tourmaline and vermiculite and adding into a dispersant and mixing to prepare a suspension solution; taking substances including methyl methacrylate and the like as monomers to prepare silicone acrylic emulsion; mixing the silicone acrylic emulsion with substances including water, titanium dioxide and other auxiliary agents and the like to obtain a mixed solution; and finally, adding the suspension solution and a cross-linking agent into the mixed solution and stirring and mixing to obtain the internal wall water-based latex paint capable of purifying the air. According to the latex paint prepared by the invention, negative ions are added so that the effects of purifying the air and catalyzing formaldehyde can be realized and the paint is good for human health; and the latex paint has stable performances and does not easily have a layering phenomenon after being stored for a long time, and the quality of indoor environment can be improved.

Description

technical field [0001] The invention discloses a preparation method of water-based latex paint for air-purifying interior walls, which belongs to the field of latex paint. Background technique [0002] At present, the interior wall paints on the market are basically emulsion products. From the variety of emulsions, the main varieties of interior wall coatings in my country include acrylate emulsions, tertiary vinegar emulsions, polyvinyl acetate emulsions, and ethylene-vinyl acetate emulsions. According to the gloss of the coating film, the latex paint for interior walls can be divided into flat, semi-gloss and glossy. Low-cost high-pigment volume concentration interior wall latex paints are currently used in more than 60% of our country. This type of latex paint mainly uses styrene-acrylic and pure acrylic emulsions as film-forming substances. Unstable, for example, it is easy to cause powdering of the coating film, and the production process requires a large amount of ad...

Problems solved by technology

[0005] The technical problem mainly solved by the present invention: Aiming at the problems that the current production process of latex paint requires a large amount of additives and solvents, causes great indoor pollution, is not environmentally friendly, and has poor storage stability and is easy to delaminate, it provides an air-purifying inner wall The preparation method of water-based latex paint, the present invention first ball-mills talc powder, tourmaline and vermiculite, then adds them into a dispersant and mixes them to obtain a suspension, and then uses methyl methacrylate and other substances as monomers to prepare a silicon-acrylic emulsion. The silicon-acrylic emulsion is mixed with water, titanium dioxide, other additives and other substances to obtain a mixed solution, and finally a suspension and a cross-linking agent are added to the mixed solution, and after stirring and mixing, the water-based latex paint for purifying air interior walls can be obtained, which is prepared by the present invention Adding negative ions to the obtained latex paint can achieve the effect of purifying the air and catalyzing formaldehyde, which is beneficial to human health, and the performance of the latex paint is stable, and the phenomenon of stratification is not easy to occur after long-term storage, which can improve the quality of the indoor environment
