Problems solved by technology

[0003] Although water-based coatings can reduce the pollution to the atmosphere, there are still organic substances in the 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. Therefore, it is necessary to provide a Coatings that remove organic matter and purify the air

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally 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 the pollution to the atmosphere, there are still organic substances in the 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. Therefore, it ...
