Abstract

The invention discloses an interior wall coating and a preparation method thereof. The interior wall coating is prepared from the following raw materials in parts by weight: acrylic resin, silicone acrylic resin, modified bamboo charcoal powder, hyalophane powder, talcum powder, a styrene-acrylic emulsion, kieselguhr, ash calcium powder, a defoaming agent, a wetting dispersant, a coalescing agent, a flatting agent and an organic solvent. The preparation method comprises the steps of firstly adding the defoaming agent, the wetting dispersant, the coalescing agent, the flatting agent and other raw materials to a mixing bowl for mixing evenly to obtain a mixture; grinding the mixture through a sand mill, wherein the fineness of the ground material is smaller than or equal to 10microns; and finally pouring the ground material and remaining raw materials to the mixing bowl for stirring homogenization treatment. The interior wall coating is capable of effectively adsorbing harmful gases in indoor air, regulating the indoor humidity in real time and improving the indoor environment, and is simple in preparation, low in cost, good in paint film property and high in covering power.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to an interior wall coating and a preparation method thereof. Background technique [0002] Interior wall paint is an important part of building decoration materials, mostly made of emulsion, deionized water, pigments and other additives. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it like this: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a solid adhesion, certain strength, and continuity. Thin film, the film formed in this way is commonly called coating film, also known as paint film or coating." It belongs to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compound. According to the classification of modern chemical products, coatings belong to fine chemical industry Products, modern coatings are gradually...
