Problems solved by technology

Most of the currently disclosed latex paints use low-formaldehyde or formaldehyde-free emulsions as raw materials. Although indoor free formaldehyde can be reduced to a certain extent, there is no significant improvement in indoor air purification. Some also add a certain amount of antibacterial agents to latex paints. In order to sterilize and purify the air for a long time, but the general antibacterial agent is pure physical adsorption, and the purification efficiency is low

Abstract

The invention discloses low-VOC (volatile organic compounds) odorless stain-resistant emulsion paint for interior walls and a method for preparing the low-VOC odorless stain-resistant emulsion paint. The low-VOC odorless stain-resistant emulsion paint is made of pure acrylic emulsion, rutile titanium dioxide, silicon micropowder, diatomite, dispersing agent, antifoaming agent, antifreezing agent, film forming auxiliary, stain-resistant agent, antiseptic mould inhibitor, thickener, pH (potential of hydrogen) modifier and water. The preparation method includes: adding the components into a reactor and well mixing to obtain the emulsion paint. The low-VOC odorless stain-resistant emulsion paint for interior walls is accordant with the limited quantity of harmful substance in interior wall paint of indoor decoration materials GB / 18582-2008, and is low in VOC content, odorless, free of indoor air pollution, capable of purifying air, fine in stain resistance effect of formed emulsion films, applicable to indoor decoration of various places, and especially applicable to decoration of interior walls of household, hospitals, schools and the like.

Description

technical field [0001] The invention relates to a paint for interior wall decoration, in particular to a low-VOC, clean, odor-resistant and stain-resistant interior wall latex paint and a preparation method thereof. Background technique [0002] With the rapid development of the paint industry, paint decoration has become more and more common. Commonly used interior wall latex paints are generally based on styrene-acrylic and vinegar-acrylic, and contain ethylene glycol, propylene glycol antifreeze and alcohol ester film-forming aids. There are many, but its volatile organic compound (VOC) content is high, such as free formaldehyde content is high, it contains APEO which is potentially harmful to the environment, and it has a strong smell. After decoration, it often has cough, sore throat, and unbearable irritation. Odor occurs, causing serious damage to the human respiratory tract and affecting human health. At the same time, this type of interior wall latex paint film has ...
