Problems solved by technology

[0002] The current latex paints are mostly synthetic resin emulsion paints, and the varieties are relatively complicated. The comprehensive performance of pure acrylic latex paints is better. Poor elastic performance, insufficient elongation and toughness, many cracks and peculiar smells will appear, and it has no effect on purifying and sterilizing indoor air, which cannot meet people's requirements for indoor green environmental protection.

Abstract

The invention discloses an environment-friendly latex paint and a preparation method thereof, and relates to the technical field of environment-friendly latex paints. The latex paint comprises the rawmaterials of pure acrylic elastic emulsion, silicone acrylic resin, rosin glycerin ester, tetraethoxysilane, calcined kaolin, aerated aluminum powder, modified nano bamboo charcoal powder, propanediol, diethylenetriamine, ammonium metatungstate, dispersant, wetting agent, defoamer, coalescing agent and deionized water. The method comprises the steps of mixing, agitating and grinding of the raw materials, and then the latex paint is obtained. The latex paint has the advantages of being green and environmental friendly, free from odor, excellent in film forming performance and good in decorative effect; the paint film of the latex paint has excellent elasticity, strong covering power and a more durable humidifying function, and the latex paint has excellent durability, water resistance, scrub resistance and dirt resistance while certain refreshing and sterilizing effects on an indoor environment can be achieved, so that the indoor environment is effectively improved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly latex paint, in particular to an environment-friendly latex paint and a preparation method thereof. Background technique [0002] The current latex paints are mostly synthetic resin emulsion paints, and the varieties are relatively complicated. The comprehensive performance of pure acrylic latex paints is better. Poor elasticity, insufficient elongation and toughness, many cracks and peculiar smells will appear, and at the same time, it has no effect on purifying and sterilizing indoor air, and it cannot meet the requirements of people for indoor green environmental protection. Contents of the invention [0003] Aiming at the problems existing in the prior art, the invention provides an environment-friendly latex paint and a preparation method thereof. This kind of latex paint is green and environmentally friendly, has no peculiar smell, has excellent film-forming performance and go...
