High-hardness and scratch-resistant interior wall finish coating and preparation method thereof

Abstract

The invention relates to a high-hardness and scratch-resistant interior wall finish coating and a preparation method thereof. The coating is mainly prepared from the following components in parts by mass: 30-50 parts of water, 0.2-0.3 parts of a pH regulator, 0.5-1.0 part of a water-based dispersant, 0.5-1.0 part of a water-based wetting agent, 0.2-0.3 parts of a water-based defoaming agent, 2-7 parts of wax powder, 1-5 parts of silica powder, 1-3 parts of kaolin, 1-3 parts of white carbon black, 1-7 parts of mica sheets, 30-40 parts of emulsion, 2-4 parts of an anti-freezing agent, 1-2 parts of a coalescing agent, 0.3-0.5 parts of a preservative and 2-5 parts of a water-based thickening agent. The interior wall finish coating provided by the invention overcomes the defects that the existing interior wall finish-coat paint cannot have a decoration effect, high paint film performance, coating hardness, scratch resistance, fine and smooth frosted hand feeling and the like at the same time. According to the invention, the wax powder, the silica powder and other preferable pigments and fillers are adopted and matched with the technologically mature mica sheets having a pearlescent effect as a decoration filler, and the material surface modification and dispersion system is optimized, so that the finish coating has the advantages of a decoration effect, good paint film performance, high coating hardness, scratch resistance, fine and smooth frosted hand feeling and the like.

Description

technical field [0001] The invention relates to a high-hardness and scratch-resistant interior wall finish paint, which is applied in the production field of interior wall finish paint. Background technique [0002] The finish paint is a kind of coating with a wide range of uses, which can have excellent protective effects on various coatings. It has functions such as waterproof, moisture-proof, acid and alkali resistance, frost resistance, yellowing resistance, mildew resistance, and self-cleaning. At the same time, the finish paint has the advantages of high transparency and good adhesion, and can be applied to the surface decoration and decoration of cement walls, bricks, stones, glass, plastics, metals, real stones, textures, imitation stones, art paints and other materials inside and outside buildings. Protect. For example, in the decorative application of real stone paint on exterior walls, the unevenness produced by natural colored sand is easy to accumulate dust on ...
