Aqueous coating for decorating inner wall of antifouling building and preparation method of aqueous coating

Abstract

The invention discloses an aqueous coating for decorating inner walls of antifouling buildings. The aqueous coating comprises the following components in parts by weight: 10-20 parts of deionized water, 0.5-0.8 part of a wetting dispersant, 0.1-0.3 part of a defoaming agent, 1-2 parts of propylene glycol, 15-20 parts of titanium dioxide, 5-8 parts of kaolin, 5-10 parts of talcum powder, 8-10 parts of wollastonite in powder, 2-5 parts of a nano stain-resistant additive, 30-40 parts of nano acrylic emulsion, 0.1-0.5 part of bactericide, 1-2 parts of a coalescing agent, 0.1-0.2 part of a PH adjusting agent and 0.3-0.5 part of a thickening agent. According to the aqueous coating, the nano acrylic emulsion is adopted as a base material, and the functional nano stain-resistant additive is added, so that a coated film has excellent resistance to multiple ordinary dirty marks, the sufficient emulsion use amount together with superfine pigment and packing ensures the tightness of the coated film, stains are effectively prevented from invading and are easy to clean, the coating is very good in adhesion to the base surface of an inner wall, resistant to water and alkali, high in covering property, large in coating area and good in construction performance.

Description

[0001] technical field [0002] The invention belongs to the field of building materials and relates to a paint, in particular to a water-based paint for anti-fouling interior wall decoration of buildings and a preparation method thereof. Background technique [0003] With the continuous progress of society, people have higher requirements for interior wall coatings. In addition to decoration, people pay more attention to environmental protection and high performance. Traditional interior wall coatings, such as latex paint, have the characteristics of good decoration, low cost, and convenient construction. However, because the paint film itself is relatively loose, it cannot form a really dense paint film and has air permeability, so it cannot achieve good durability. dirty effect. [0004] Existing paints include resins, pigments, solvents and additives. Most of the resins are acrylic resins, alkyd resins, phenolic resins, amino resins, epoxy resins, etc. Due to the shape...

Traditional interior wall coatings, such as latex paint, have the characteristics of good decoration, low cost, and convenient construction. However, because the paint film itself is relatively loose, it cannot form a really dense paint film and has air permeability, so it cannot achieve good durability. dirt effect

[0004] Prior art coatings include resins, pigments, solvents and additives, resins are mostly acrylic acid, alkyd resins, phenolic resins, amino resins, epoxy resins, etc., due to resin Due to the shape of its own structure, surface structure and other reasons, the anti-fouling property to pollutants is not obvious
