Problems solved by technology

However, some real stone paints will turn white after being exposed to wind and sun, and the color will gradually fade, losing the original perfect texture of real stone paints, and real stone paints are not water-resistant
The main reason is that the quality of the emulsion used in the coating is not high. Under normal circumstances, the film-forming aid acrylate has strong stability, but some manufacturers use substances such as hydroxyethyl cellulose to prepare real stone paint. Increase the viscosity, these are relatively soluble in water, which greatly reduces the water resistance of the coating. The water absorption rate of the general acrylate coating after spraying is only 0.42%; while adding 0.4% hydroxyl on the basis of the above coating Ethyl cellulose, the water absorption rate soars to 4.3%, it is not resistant to blisters, and its corrosion resistance is greatly reduced

Abstract

The invention discloses a production process of a water-soaking-resistant and corrosion-resistant stone-like coating, and belongs to the technical field of chemical production. According to the production process, the stone-like coating is prepared from natural colored sand. The process is simple. The raw material source is wide. The stone-like coating has the characteristics of good weather resistance, color retention, corrosion resistance, water resistance, aging resistance, capability of prolonging the service life of a building and the like; the stone-like coating has the advantages of flexibility, capability of effectively covering tiny cracks, cracking resistance, good flexibility, collision resistance and the like; the stone-like coating is rich in expressive force, strong in stereoscopic impression, good in plasticity, and good in alkali-acid resistance and ultraviolet resistance; the stone-like coating is stable in color, free of fading, wide in application range, high in adhesive force, waterproof and breathable; and the stone-like coating has good waterproof, breathable, environment-friendly, safe, aging-resistant, cracking-resistant, corrosion-resistant and water-soaking-resistant performance.

Description

technical field [0001] The invention belongs to the technical field of chemical production, in particular to a production process of blister-resistant and corrosion-resistant genuine stone paint. Background technique [0002] Real stone paint has a three-dimensional hard coating, and the surface of the coating can also be coated with finish varnish to adjust the desired tone and gloss, so as to obtain a coating with rich texture, various colors, and a decorative surface similar to natural stone such as granite. It enhances the decorative effect, so it is deeply loved by people. Real stone paint is composed of synthetic resin emulsion and artificial colored sand and other materials. The source of raw materials is abundant, and the paint production process and equipment are relatively simple. Due to the use of stable materials such as ceramic granules and colored aggregates, it will not change or fade due to the influence of wind and rain, sunlight, sulfur dioxide gas, etc., ...
