High-waterproof colorful stone-like paint

Abstract

A high-waterproof colorful stone-like paint is composed of the following raw materials in percentage by weight: 11 to 15% of soap-free silicone acrylic emulsion, 2 to 4% of aqueous fluorocarbon resin emulsion, 54 to 63% of natural colorful sand, 2 to 4% of calcium carbonate and magnesium carbonate powder, 14 to 20% of water, 4 to 6% of natural rock sheets, 0.1 to 0.5% of water repellent, 0.1 to 0.3% of antifoaming agent, 0.1 to 0.3% of wood fiber, 0.1 to 0.2% of cellulose ether, and 1 to 2% of film-forming auxiliary agent. The soap-free silicone acrylic emulsion and aqueous fluorocarbon resin emulsion are mixed and used as the adhesive of the stone-like paint. Natural colorful sand with different finenesses is matched with natural rock sheet to prepare the stone-like paint. The prepared stone-like paint has the advantages of high waterproofness, natural color and luster, stone-like texture, good imitation effect, and high adhesive strength. The coating will not fade and become loosen and scratched. After drying, the paint film is compact, and moreover the paint has the advantages of strong adhesive force, large hardness, cracking resistance, alkali / acid resistance, corrosion resistance, no odor or toxicity, safety, and environment-friendliness.

Description

technical field [0001] The invention belongs to the technical field of building exterior wall coatings, and in particular relates to a highly water-resistant colorful real stone paint. Background technique [0002] Real stone lacquer is a kind of thick paste paint imitating natural stone, marble and granite. It has natural color and the texture of natural stone. It can provide various three-dimensional pattern structures and can visually show the elegance and solemn beauty of the whole building. , is the best substitute for dry-hanging stone on exterior walls. Real stone paint is generally made of high molecular polymer, natural colored sand and related additives. [0003] Real stone paint has good acid and alkali resistance, good corrosion resistance, non-combustibility, strong decoration and good weather resistance. However, the emulsion content in real stone paint is relatively large, and the emulsion used in traditional real stone paint has more emulsifiers. In additio...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that the traditional real stone paint has poor water resistance, and the coating is easy to whiten and become loose when exposed to water, the present invention provides a kind of high water resistance colorful real stone paint. Its raw material composition and weight percentage ratio are as follows: soap-free silicon acrylic emulsion 11~ 15%, water-based fluorocarbon resin emulsion 2-4%, natural colored sand 54-63%, Shuangfei powder 2-4%, water 14-20%, natural rock slice 4-6%, water repellent 0.1-0.5%, disinfectant Foaming agent 0.1-0.3%, wood fiber 0.1-0.3%, cellulose ether 0.1-0.2%, and film-forming aid 1-2%
