Abstract

The invention provides water-based aluminum alloy baking varnish. The water-based aluminum alloy baking varnish is prepared from the following materials in parts by weight: 40-45 parts of LH-WB09 resin, 10-13 parts of 325 amino resin, 0.2-0.3 part of wetting and leveling agent, 0.2-0.4 part of dispersing agent, 0.1-0.3 part of defoaming agent, 0.3-0.5 part of reinforcing agent, 0.2-0.5 part of thickening agent, 0.7-0.9 part of water-based color concentrate and 40-43 parts of deionized water, wherein the LH-WB09 resin is prepared from the following materials in parts by weight: 3.3-3.8 parts ofacrylic acid, 3.0-3.5 parts of 2-hydroxyethyl methacrylate, 7-9 parts of styrene, 9-10 parts of methyl methacrylate, 7.0-7.5 parts of butyl acrylate, 3-5 parts of isoborneol methacrylate, 4-5 parts of n-butyl methacrylate, 3-5 parts of epoxy resin, 0.7-0.9 part of benzoyl peroxide, 0.2-0.5 part of sulfenyl ethanol, 3.5-4.5 parts of N,N-dimethylethanolamine, 45-50 parts of mixed solvent and 7-12 parts of deionized water. The invention provides the water-based aluminum alloy baking varnish and a preparation method thereof. The water-based aluminum alloy baking varnish prepared through the preparation method has the advantages of being resistant to soaking in absolute ethyl alcohol and boiling in boiling water and strong in adhesive force.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a water-based aluminum alloy baking paint and a preparation method thereof. Background technique [0002] With the increasing awareness of environmental protection and the corresponding introduction of environmental protection regulations in various countries, water-based coatings have become an important direction for the development of coatings. It can not only reduce solvent emissions in production, but also easily adjust the construction viscosity in an environmentally friendly manner. [0003] Water-based aluminum alloy baking paint uses water as the dispersion medium, completely eliminates the harm of organic solvents to the human body, and has incomparable advantages over traditional oil-based paints, such as health and environmental protection, low-carbon energy saving, high utilization rate, and good safety. Water-based aluminum alloy baking varnish generally r...
