On the basis of the existing decoration materials, researchers in the industry need to solve the problem of endowing the decoration materials with more functions and improving the value added value of the decoration materials.

The coating is a common home decoration material, is coated on the surface of a protected or decorated object, and can form a firmly attached continuous film with the coated object. Generally, the coating is a viscous liquid prepared by using resin (or oil or emulsion) as a main material, adding corresponding auxiliary agents, adding or not adding pigments and fillers and using an organic solvent or water. At present, in home decoration, the aspects of beauty, comfort and the like are concerned, and the properties of residents are closely related, and in the existing building decoration industry, special paint is smeared on the surface of a wall body of a house, so that the performance of the wall body is greatly improved through the effect of the paint.

In the household environment, various flammable materials are more and more commonly used, and the fire prevention work is very important. One of the most common fire-retardant treatments is the use of fire-retardant coatings. The fireproof paint is a special paint used for coating the surface of a substrate, reducing the flammability of the surface of a coated material, retarding the rapid spread of fire and improving the fire endurance of the coated material. The fireproof coating has a good protective effect on a base material, and is suitable for places with visible open fire such as kitchens and the like and places with flammable plates such as wood cabinets, floors and the like. In case of fire, the fire-retardant coating which is difficult to burn in case of fire can gain time for fire extinguishing and personnel evacuation. However, the fireproof coating in the prior art has the defects of complex formula, high cost, poor fireproof performance of some products, easy cracking and influence on use.
