Inorganic dry powder texture coating

Abstract

The invention provides an inorganic dry powder texture coating, which comprises the following components in percentage by weight: 12 to 15 percent of gray calcium powder, 20 to 30 percent of quartz powder, 10 to 15 percent of quartz sand, 30 to 40 percent of coarse calcium powder, 0.5 to 0.6 percent of hydroxypropyl methyl cellulose (HPMC), 1 to 2 percent of redispersible emulsion powder, 1 to 2 percent of polyvinyl alcohol powder and 0.3 to 0.4 percent of wood fiber. The coating is environmentally-friendly, and most used raw materials are readily available inorganic materials, so that pollution caused by the volatilization of an organic solvent into the atmospheric air is avoided, and harm to body health and possible risks such as fire and the like during production, transportation, storage and construction of the coating are eliminated; the coating is easy and convenient to construct, can be directly constructed on a qualified substrate without any primer, is suitable for various construction tools and has good texture and a high decorating property, and pigments can be doped as required; and the coating has high weather resistance, is free from peeling, is cracking-resistant, is convenient to transport, and is suitable for building coating in various environments and under various climate conditions.

Description

technical field [0001] The invention relates to a chemical material, in particular to an inorganic dry powder texture coating. Background technique [0002] Most of the current architectural coatings are organic coatings with synthetic resin as the main film-forming substance. The raw material of synthetic resin mainly comes from petroleum, and petroleum is a kind of non-renewable resource. In addition, a certain amount of organic solvents are used in the manufacture and construction of organic coatings. These organic solvents also come from petroleum, and these organic solvents will be directly discharged into the atmosphere during the production and construction of coatings, which causes resource pollution. A large amount of waste will cause direct or indirect harm to the environment and human body. Inorganic coatings use inorganic substances as the main film-forming substances, and the main sources of film-forming substances are natural ores. These raw materials are abu...

Problems solved by technology

[0003] In order to achieve a certain decorative effect, organic coatings have high requirements on the flatness of the substrate and require multiple constructions. The coating usually has defects such as poor adhesion, easy foaming, cracking, and poor durability, and the surface effect is mainly flat. Difficult to make various three-dimensional or texture effects
