Slow-release mildew-proof real stone paint and preparation method thereof

Abstract

The invention relates to a slow-release mildew-proof real stone paint and a preparation method thereof. The coating is mainly prepared from the following components in parts by weight: 100-150 parts of water, 1-2 parts of hydroxyethyl cellulose, 0.5-1 part of bentonite, 1-2 parts of a pH regulator, 20-30 parts of superfine zinc sulfide, 120-150 parts of modified silicone acrylic emulsion, 0.5-1 part of a defoaming agent, 0.5-1 part of a bactericide, 0.5-1 part of a capsule type mildew preventive, 5-10 parts of an anti-freezing agent, 5-10 parts of a coalescing agent, 1-2 parts of a thickening agent and 600-800 parts of natural colored sand. The invention overcomes the quality problem that mildew spots are easy to grow after long-time raining and solarization in the existing outer wall real stone paint, and the defects that the mildew preventive added in the existing outer wall real stone paint is not environment-friendly, poor in effect and the like, and the capsule type mildew preventive containing the preferable compound mildew preventive and the superfine zinc sulfide are specially added in the system, so that the mildew-proof performance of the exterior wall real stone paint is improved. By matching with other preferable components and dosage proportions in the system, the mildew-proof coating has the advantages of being good in environmental protection property and lasting in mildew-proof effect.

Description

technical field [0001] The invention relates to a slow-release anti-mildew real stone paint and a preparation method thereof, which are applied in the field of real stone paint production. Background technique [0002] Most of the existing real stone paints for exterior walls are water-based paints. Water-based coatings are generally composed of water, cellulose, base materials, pigments and fillers, dispersants, antifreeze agents, film-forming aids, thickeners, defoamers, and pH regulators. The organic solvents in water-based paints are basically replaced by water, which provides a living environment for molds. At the same time, due to the presence of cellulose, water-based paints are very easy to breed bacteria and molds. Therefore, the existing real stone paint for exterior walls is prone to quality problems of mildew spots after being exposed to the sun for a long time. In order to ensure the stability of real stone paint for exterior walls during production and storag...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the existing real stone paint for exterior walls exposed to the sun for a long time, it is easy to have mildew spots quality problems, and the antifungal agent added to the existing real stone paint for exterior walls has the disadvantages of not being environmentally friendly and having poor effects. The invention provides a slow-release anti-mildew real stone paint and its preparation method, which is specially added to the system by adding a capsule-type anti-mold agent and ultra-fine zinc sulfide containing a preferred compound anti-mold agent, and cooperating with other preferred anti-mold agents in the system. The components and their dosage ratio have the advantages of good environmental protection and long-lasting mildew resistance
