Problems solved by technology

[0002] Coatings are a mixture of polymer substances and ingredients, and can be coated on the surface of the substrate to form a new type of polymer material that adheres firmly and continuously. All coatings that use water as a solvent or dispersion medium can be called water-based coatings. Water-based coatings are The development trend of the architectural decoration industry can save resources, reduce the risk of fire during construction, and reduce air pollution. It can be directly coated on wet surfaces and humid environments. It has good adaptability to the surface of the substrate. Currently, most of the coatings used in the market are Synthetic resin emulsion or acrylic is used as the base material, and it is synthesized by various pigments, fillers and additives. The main disadvantage of this kind of paint is that the elasticity of the paint film is easy to age, resulting in a decrease in elongation, and it cannot effectively protect the strength of the bottom layer of the wall. As a result, the wall surface cracks and falls off, which not only affects the appearance of the building, but also causes the wall surface to crack and cause water leakage on the wall surface.
