Dry powder crackle coating and construction method

Abstract

The invention discloses a dry powder crackle coating and a construction method thereof. The coating is prepared from components in percentage as follows: 30%-50% of white carbon black, 15%-30% of heavy calcium powder, 10%-20% of diatomite, 5%-10% of ash calcium powder, 4%-20% of redispersible rubber powder, 0-5% of ordinary Portland cement and 5%-10% of auxiliary materials. Meanwhile, the invention further discloses the construction method of the dry powder crackle coating. The crackle effect is formed by adopting clear water as a solvent and combining a printing roller with concave-convex patterns. The crackle coating prepared with a formula and the construction method has natural crackle texture, good stereo effect and uniform crackles. Raw materials in the formula are natural inorganic materials and convenient to transport, the clear water is adopted as the solvent, the problem of pollution caused by traditional crackle paint is solved, and the coating is healthy and environment-friendly. The bottom and the surface of the dry powder crackle coating are made of the same material, and the preparation and construction processes are simple and convenient to operate.

Description

technical field [0001] The invention relates to an interior wall paint and a construction method thereof, in particular to a dry powder crack paint with a crack effect and a construction method thereof. Background technique [0002] Crackle paint can produce uniform texture and patchwork cracks, which is used by people to decorate objects and walls. Traditional cracked paint uses a large amount of organic solvents, which pollutes the environment and poses health risks to construction workers. Crackle paint uses the viscosity, surface tension and curing speed of the paint to cause the shrinkage of the coating film surface, resulting in the effect of cracks. Its viscosity is mainly adjusted by the matching cracking water, and the speed and distance of the gun during spraying construction must be uniform. To achieve the special cracking effect, there are certain requirements for the technical proficiency of the construction personnel, and the construction process is relatively...
