Problems solved by technology

[0003] Although water-based coatings can reduce air pollution, there are still organic substances in water-based coatings. These organic substances exist in the coatings as fillers and substrates, and their content is about 2-12%, which will still pollute the environment.
[0004] The main component is acrylic water-based paint, which is widely used because of its good adhesion, will not deepen the color of wood, and is low in cost. However, its hardness is soft and its mechanical properties are not high, which limits its use. Therefore, it is necessary to provide A high-strength and environmentally friendly water-based coating

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-strength environmental-friendly water-based coating. Background technique [0002] Coating is a new type of polymer material, which has the characteristics of uniformly adhering to the surface of the substrate material to form a firm and crack-free film. Traditional coatings use organic substances as solvents, which will release volatile organic substances during processing and production, which will pollute the environment. Water-based coatings use water as a solvent, which can save a lot of resources, eliminate the risk of fire during construction, and reduce air pollution. [0003] Although water-based coatings can reduce air pollution, there are still organic substances in water-based coatings. These organic substances exist in the coatings as fillers and substrates, and their content is about 2-12%, which will still pollute the environment. [0004] The main compon...
