Abstract

The invention discloses a cheese mixed linseed oil natural coating and a preparation method thereof. The coating is prepared from the following components in part by weight: 300 to 400 parts of activated cheese, 300 to 400 parts of emulsified linseed oil, 10 to 30 parts of emulsifier, 5 to 10 parts of wetting agent, 1 to 4 parts of preservative, 150 to 300 parts of water, and 0 to 1490 parts of other additives. Waste water, waste residue and a coating dry film produced by the coating production can be degraded, and environmental protection pressure can be reduced. The coating dry film can alsoabsorb formaldehyde and purify indoor air; the coating dry film releases no harmful substances.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a cheese mixed linseed oil natural coating and a preparation method thereof. Background technique [0002] Water-based architectural coatings (emulsion paints) are increasingly widely used in the Chinese market due to their rich colors, convenient construction, and easy renovation. Among them, interior wall paint has become the interior decoration material for most consumers. The main components of latex paint include: synthetic resin emulsion, pigments, fillers, additives, water, among which synthetic resin emulsion is a film-forming substance. The functions of latex paint include: protective function, after the construction is dried and formed into a film, the paint forms a protective film on the surface of the building to block air pollutants and prolong the life of the building; decorative function, the color, luster and shape of the latex paint can be adjus...
