Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an air-purifying functional water-based coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy, environmental protection has been increasingly put on the agenda. After the improvement of living material conditions, people pay more attention to the quality of life and the health and pollution-free living environment. Coatings for interior decoration are one of the materials that people have always been in contact with in the home environment, and this type of material is closely related to people's lives. At present, most of the common coatings on the market are solvent-based coatings. Due to the application of a large amount of volatile and toxic organic solvents in the process of preparation and use of this type of coatings, it has caused serious environmental pollution and directly endangered human hea...
