High-water-resistant colorful stone-like paint

Abstract

The invention provides a high-water-resistant colorful stone-like paint which comprises the raw materials of, by mass, 5-12 parts of ethylene glycol mo nobutyl ether acetate, 70-130 parts of sintering color sand, 3-8 parts of heavy calcium carbonate, 20-24 parts of silicone acrylic emulsion, 0.5-2.5 parts of water repellent, 5-10 parts of thixotropic agent, 2.5-8.5 parts of mildew preventive, 1-8 parts of kaolin, 4-9 parts of anti-freezing agent, 2-6 parts of dispersing agent and 30-50 parts of water. The high-water-resistant colorful stone-like paint has the advantages that the prepared stone-like paint product is large in film hardness, free of water blush phenomenon, capable of preventing yellowing, high in bonding strength and good in weather resistance; the construction performance, the crack resistance, the acid and base resistance, the corrosion resistance and the like are excellent, and the stone-like paint is non-toxic, odourless, free of radioactive contamination and harm to human body, safe and environment-friendly.

Description

technical field [0001] The invention belongs to the field of real stone paint research and development, in particular to a kind of high water resistance 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 addition, th...

AI Technical Summary

Problems solved by technology

However, the emulsion content in real stone paint is relatively large, and the emulsion used in traditional real stone paint has more emulsifiers. In addition, the additives of real stone paint contain a large number of hydrophilic groups, resulting in a higher water absorption rate of real stone paint.

However, the coating of real stone paint is generally thicker. When it encounters continuous rainy weather, the absorbed water is not easy to discharge. The coating soaked in water for a long time will appear whitish and soft, and the color will become lighter. After the coating dries, the color will basically return to its original state, but the color will change a lot if it goes back and forth many times
