Problems solved by technology

The current environmentally friendly latex paint mostly uses low-formaldehyde or formaldehyde-free emulsions as raw materials. Although it can reduce indoor free formaldehyde to a certain extent and reduce environmental pollution, it does not significantly improve indoor air purification.
There is also a certain amount of inorganic antibacterial agent added to a small amount of environmentally friendly latex paint, the purpose is to sterilize and purify the air for a long time, but the general inorganic antibacterial agent is pure physical adsorption, the mechanism of action is single, and the antibacterial particles are prone to secondary agglomeration, resulting in reduced purification efficiency

Abstract

The invention discloses environment-friendly inner wall latex paint. The environment-friendly inner wall latex paint is prepared from the following raw materials in parts by weight: 50 to 70 parts of nano particles, 40 to 60 parts of expanded perlite, 30 to 40 parts of cellulose, 15 to 30 parts of styrene-acrylic emulsion, 10 to 20 parts of nano active carbon, 8 to 15 parts of latex paint additives, 5 to 10 parts of filler, 2 to 6 parts of inorganic pigments and 50 to 80 parts of deionized water. The environment-friendly inner wall latex paint is nontoxic and harmless in the production and construction application, capable of decomposing harmful gases and purifying the air, and excellent in abrasion resistance and aging resistance at the same time.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly latex paint for interior walls and a preparation method thereof. Background technique [0002] At present, people pay more and more attention to their own health, and they often put health in the first place when choosing interior paint. Among the indoor pollution sources, the most important is formaldehyde from adhesives. Formaldehyde is a colorless, pungent gas with a strong odor. It is a highly toxic substance and has been identified as a carcinogenic and teratogenic substance by the World Health Organization. [0003] In recent years, the state has promulgated a series of standards and regulations to control indoor air quality. People are more cautious about the selection of environmentally friendly latex paint for interior decoration. Therefore, the production of environmentally friendly and air-purifying indoor latex paint has become the core issue ...
