Problems solved by technology

However, the stain resistance of traditional interior wall emulsions in the existing market is insufficient, and most of them use damaged paint film to achieve the effect of stain resistance, which not only damages the cleanliness of the wall surface, but also fails to meet the application requirements

Abstract

The invention discloses a weather-resistant and stain-resistant pure acrylic emulsion composition for real stone paint. 25 parts, 3-8 parts of acrylic acid, 5-12 parts of R-acrylate, 5-7 parts of acrylic grafted starch, 0.2-0.8 parts of polyurea crosslinking monomer, 2-4 parts of polyamide resin, 1-nanometer alumina 2.5 parts, emulsifier 2-6 parts, persulfate 0.6-3 parts. The pure acrylic emulsion composition of the present invention is easy to form a tight paint film layer, has excellent impact resistance, tear resistance and abrasion resistance, excellent chemical corrosion resistance and weather resistance, and antifouling performance, and is used for high-grade building real stone paint Easy to deploy, high-end and high-end.

Description

technical field [0001] The invention relates to a paint emulsion, in particular to a weather-resistant and stain-resistant pure acrylic emulsion composition for real stone paint. Background technique [0002] Acrylic-based emulsion has excellent weather resistance, heat resistance, low cost and other advantages, and is one of the most widely used systems for water-based coatings. However, the hydrophilicity of the coating of the acrylic system coating is too high, and the compactness of the paint film is not perfect. [0003] Self-crosslinking acrylate emulsions are usually formed by free radical polymerization of (meth)acrylic acid (ester) monomers, crosslinking monomers, emulsifiers, buffers, initiators, and deionized water. However, most of the key additives (initiators, crosslinkers, etc.) in current acrylic resin systems of this type are harmful. [0004] Real stone paint and pure acrylic emulsion are mixed and applied on the interior or exterior walls to obtain a rea...
