Attapulgite inner wall cement paint

Abstract

The invention discloses a cement paint for interior walls of attapulgite. The key point of the technical proposal is that the cement paint for interior walls of attapulgite comprises purified attapulgite, white Portland cement, polyvinyl alcohol ultrafines, anatase titanium dioxide, droxyethylcellulose, a solid silicone defoaming agent and a fluorescent brightener VBL. The manufacturing method of the cement paint for interior walls of attapulgite comprises mixing, crashing, grinding and packaging the finished product of the cement paint for interior walls of attapulgite. The cement paint for interior walls of attapulgite is characterized by super strong adhesive force, fast-drying and firm paint film, humidity resistance, wash resistance, anti-mildew and antibacterial property and high hiding power, etc. The cement paint for interior walls of attapulgite is safe without poison and pollution and the product quality accords with the standard of GB 18582-2008 Decorating and Refurbishing Materials-Limit of Harmful Substances of Interior Architectural Coatings. In addition, the cement paint for interior walls of attapulgite is applicable to the protection and decoration of interior wall surfaces and ceilings of the building structure.

Description

technical field [0001] The invention relates to coatings, in particular to an attapulgite interior wall cement paint. Background technique [0002] The interior wall cement paint is directly painted on the inner surface of buildings or structures, which is more closely related to people's life or work. The decorative effect, coating feel, flatness, color and texture of interior wall cement paint will receive more attention from people. Interior wall cement paint will have a greater impact on the indoor environment and should have appropriate air permeability and moisture absorption. , The coating film that is completely airtight and non-hygroscopic will cause condensation on the wall, which is not conducive to the improvement of the indoor environment and the improvement of living comfort. The interior wall cement paint cannot contain toxic and harmful substances, otherwise it will cause harm to the environment and health; the interior wall cement paint must have appropriat...

Problems solved by technology

[0004] The disadvantage of the above-mentioned patent is that bentonite is selected as the main raw material in this technology, and impurities such as quartz, feldspar, zeolite, gypsum, calcite, pyrite, iron oxide minerals and cuttings are often associated with bentonite, and these associated Minerals have a great influence on the chemical composition and process performance of bentonite. The colloidal viscosity, dispersion and suspension performance of unpurified bentonite are relatively poor, so it will affect the product quality of coatings.
