Attapulgite interior wall powder coating

Abstract

The invention discloses an attapulgite interior wall powder coating. The key point of the technical proposal of the invention is that the attapulgite interior wall powder coating consists of purified attapulgite, precipitated calcium carbonate, polyvinyl alcohol ultrafines, instant sodium silicate, anatase titanium dioxide, a solid polyether defoaming agent and a fluorescent whitening agent VBL. The method for producing the attapulgite interior wall powder coating comprises the steps of material mixing, crashing, grinding into powder and packaging to obtain a finished product of the attapulgite interior wall powder coating. The attapulgite interior wall powder coating has strong adhesive force, high durability, water resistance, friction resistance and dirt resistance, and can absorb formaldehyde and volatile organic compound to purify air. The attapulgite paste interior wall powder coating is a white reference coating and can be directly adjusted in color to produce color washes of various colors; and the attapulgite interior wall powder coating is applicable to building decoration.

Description

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

AI Technical Summary

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.
