Environment-friendly flame-retardant building coating and preparation method thereof

Abstract

The invention discloses an environment-friendly flame-retardant building coating and a preparation method thereof. The environment-friendly flame-retardant building coating comprises a base coating and a surface coating; the base coating directly coats a wall surface to form a pre-coating layer, and the thickness of the pre-coating layer is 0.4-1.2 mm; and the surface coating coats the pre-coatinglayer to form a surface coating layer. The preparation method of the building coating comprises a preparation method of the base coating and a preparation method of the surface coating. According tothe invention, double-layer coating is adopted, uneven parts on a coated wall surface are perfectly filled, attractiveness of the coated wall surface is improved, and overall cost is reduced. A good adhesion effect is achieved between the pre-coating layer and the surface coating layer, and meanwhile, the oily pre-coating layer can have a better coating effect with the wall surface. The water-based surface coating layer can reduce the volatilization speed of harmful gas of the pre-coating layer, so that the effects of ensuring environment protection and health can be ensured while coating quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly flame-retardant building coating and a preparation method thereof. Background technique [0002] Architectural coating is an article used on the surface of the wall. It can form a tough protective film on the surface of the building wall. On the one hand, it can have a good decorative effect on the surface of the wall, making the surface of the wall smooth and effective. On the other hand, architectural coatings can also play a good role in isolating water vapor and preventing corrosion, ensuring the effective application of the wall for a long time. [0003] Due to the widespread use of architectural coatings, people pay more and more attention to the impact on the wall. There are also many functional architectural coatings on the market. Among them, the flame-retardant, fire-proof, thermal insulation and waterproof properties of ar...

Problems solved by technology

[0003] Due to the widespread use of architectural coatings, people pay more and more attention to the impact on the wall. There are also many functional architectural coatings on the market. Among them, the flame-retardant, fire-proof, thermal insulation and waterproof properties of architectural coatings are the most important. Several important properties of architectural coatings, but the materials that need to be added for various properties will interact with each other, and the types and amounts of raw materials need to be changed, which will directly affect some of the properties, and it is impossible to make the coating more At the same time, due to the large amount of architectural coatings used, the coating is thick, the processing of the coating is difficult, the smoothness of the coating surface cannot be guaranteed, and the coating is prone to cracks after drying. Affect the appearance of the coating and easily cause subsequent adverse effects. The most important use in the prior art is oil-based paint. However, the pollution problem of oil-based paint has not been solved and water-based paint has been produced. However, the cost and effect of water-based paint Compared with oil-based paints, they are at a disadvantage, and water-based paints have not been widely used and accepted. The use of a large number of oil-based paints cannot meet the requirements of environmental protection. In order to solve these problems, an environmentally friendly flame-retardant architectural paint is provided. The present invention provides The following technical solutions
