Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to an inorganic stone-like dry powder coating for an outer wall and a wall surface.
Background
With the protection of natural resources in China, the environmental protection and energy conservation policies of China and the stricter and stricter relevant regulations, the mining, processing and transportation costs of natural stones are continuously increased, which affects the application of the natural stones in the field of building decoration to a certain extent. In addition, the continuous promotion and development of building energy conservation also enables the application of the external wall external heat insulation technology on the building external wall to be popularized and popularized. And the stone decoration process is carried out on the heat insulation base layer, the construction process is relatively complex, and many new heat insulation forms cannot be adopted. The stone-like coating is used for imitating natural stone, has vivid effect, has good decorative effect and economic and reasonable price no matter texture or color is close to that of the natural stone, is convenient to overhaul and update at the later stage, and is adopted by more and more construction units in building decoration engineering.
The stone-like paint commonly used in the field consists of two kinds of paintOne or more kinds of water-based color particles are suspended in the water-based interlayer and pass through the interlayer onceSpraying of paintThe single-component paint for the outer wall of a building with various colors is prepared by taking acrylic resin emulsion and elastic resin solution as base materials, reasonably proportioning white quartz sand and artificially calcined color sand, matching colors and spraying by a high-pressure spray gun to form a rich stone-like coating. However, since organic components such as emulsion or latex powder are required, the environmental protection performance needs to be further improved.
Chinese patent document CN110550924A discloses an exterior wall dry powder coating, which mainly comprises the following raw materials in parts by weight: 45-50 parts of heavy calcium carbonate, 10-20 parts of ash calcium, 10-20 parts of quartz sand, 5-12 parts of porous quartz powder, 1-15 parts of cellulose ether and 21-5 parts of moisturizing lubricant HS-5. The dry powder coating for the outer wall surface has good service performance and environmental protection performance, but has poor decoration performance. If the stone-like paint is prepared by directly adding the raw materials for preparing the stone-like paint such as the colored quartz sand and the like into the raw materials, the prepared paint has poor crack resistance and cannot meet the requirements of practical application.
