Method for producing attapulgite paste interior wall coating

Abstract

The invention discloses a method for producing an attapulgite paste interior wall coating. The key point of the technical proposal of the invention is that the method for producing the attapulgite paste interior wall coating comprises the steps of material mixing, crashing, stirring, dispersion, dissolution, homogenization, emulsification, defoaming, grinding and canning to obtain a finished product of the attapulgite paste interior wall coating. The attapulgite paste interior wall coating consists of paste palygorskite clay, superfine precipitated calcium carbonate, polyvinyl alcohol ultrafines, instant sodium silicate, anatase titanium dioxide, a solid polyether defoaming agent, a fluorescent whitening agent VBL and deionized water. The attapulgite paste interior wall coating has strong adhesive force, high durability, water resistance, friction resistance and dirt resistance, and can absorb formaldehyde and volatile organic compound to purify the air. The attapulgite paste interior wall coating is a white reference coating and can be directly adjusted in colors to produce color washes of various colors; and the method for producing the attapulgite paste interior wall coating is suitable for producing environment-friendly interior wall coatings.

Description

technical field [0001] The invention relates to coatings, in particular to a production method of an attapulgite paste interior wall coating. Background technique [0002] Interior wall coatings have some characteristics different from exterior wall coatings. Interior wall coatings are directly painted on the inner surface of buildings or structures, and are 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...

Problems solved by technology

[0004] The disadvantage of the above patent is that the attapulgite clay that has not been purified and modified is used as the main raw material in this technology, and its colloidal viscosity, dispersibility and suspension performance are relatively poor, which will also affect the product quality of the coating.
