Description

technical field [0001] The invention relates to a water-based paint, in particular to an environment-friendly anti-corrosion water-based primer paint, and also relates to a preparation method of the paint. Background technique [0002] With the continuous advancement of industrialization and urbanization, environmental quality has an increasingly important impact on people's physical and mental health, so environmental quality has received more and more attention. Solvent-based coatings contain a large amount of volatile organic compounds, which waste energy and pollute the environment. The volatilization of some toxic solvents during the production and painting process and after painting will have a harmful impact on human health. At present, with the national environmental protection policy and energy conservation With the gradual implementation of emission reduction policies, the research and development direction of coatings is becoming more and more clear, which is to s...
