Description

technical field [0001] The invention relates to a paint, in particular to a water-based metal paint. Background technique [0002] Coatings include water-based coatings and solvent-based coatings. Although the coatings formed by some oil-based coatings can meet the requirements of high brightness and subsequent rapid bronzing processing, they will volatilize more harmful substances during use, causing great environmental pollution. Reach environmental protection requirements (especially the organic volatile matter limit requirements of the cigarette pack industry), and the cost is relatively high. [0003] Water-based paint is a paint that mainly uses water as a solvent. Water-based coatings have many advantages. For example, water-based coatings use water as a solvent, saving a lot of resources; water-based coatings eliminate the fire hazard during construction; reduce air pollution; environmental conditions. The organic solvent (accounting for paint) of general water-ba...
