Abstract

The invention belongs to inorganic water-based paint and a preparation method thereof in the field of environmental protection. The inorganic water-based paint comprises, by mass, 20-24% of potassium silicate, 1-3% of a modified bentonite formaldehyde adsorbent, 2-3% of tetrapod-like zinc oxide whiskers, 1-3% of modified sepiolite, 16-20% of titanium dioxide, 20-27% of heavy calcium powder, 0-2% of montmorillonite-loaded acrylic acid, 0-3% of bentonite inorganic gel, 0-7% of glass powder, 0-1% of cellulose, 0 to 2% of odorless emulsion, 0 to 0.4% of 2-imidazolidinone, 0 to 0.6% of a hydrophobic reinforcing agent and 20 to 30% of water. and potassium silicate is adopted as a main film forming substance, tetrapod-like zinc oxide whiskers, a modified bentonite formaldehyde adsorbent, modified sepiolite and the like are compounded, and the prepared inorganic water-based paint is high in purification efficiency, good in purification durability and free of toxicity and pollution.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to an inorganic water-based paint and a preparation method thereof. Background technique [0002] According to the data of the National Bureau of Professional Statistics, 80% of the air pollution caused by indoor decoration in the country comes from excessive formaldehyde. For this reason, people have done a lot of research on air purification and developed various materials with the function of purifying air, such as CN100467554 and CN102964932B , these two inventions are mainly based on the addition of four-needle zinc oxide whiskers, adsorption materials, acrylate emulsions, etc. to the latex paint. The film-forming substance is acrylate emulsion, which is not only toxic and carcinogenic, but also has poor air permeability. , resulting in the addition of four needle-shaped zinc oxide whiskers and adsorption materials can not fully play its role in purification....
