Abstract

The invention relates to a water-borne glass baking paint which is characterized by comprising the following components by the weight percentage: 20-60% of water-borne epoxy resin, 10-40% of low methyl etherified amino resin, 0-18% of water-borne acrylic resin modified polyurethane, 3-30% of a color concentrate dye or colorant, 0.1-0.8% of a leveling agent, 0.1-1.0% of a wetting agent, 0.1-0.8% ofan adhesive agent, 0.1-0.8% of an antioxidant, 0.1-0.6% of a defoamer, 0.1-0.4% of a bactericide, 0.5-6% of a pH regulator, and the balance being deionized water. The invention also discloses a preparation method of the water-borne glass baking paint. Compared with the prior art, the water-borne glass baking paint has good adhesion force on glass and other substrates, excellent alcohol resistance, excellent water resistance, excellent wear resistance, and no need of use of additional organic solvents. The preparation method is simple and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based glass baking varnish and a preparation method thereof. Background technique [0002] The coating protection and decoration of glass and glass products have a wide range of needs in industrial and civil fields, such as wine bottles, cosmetic bottles, perfume bottles, lighting, home decoration glass products and glass instruments, etc., all need to be coated with protective and decorative coatings on the surface. layer. At present, most of the glass coatings used in China are solvent-based products, which are relatively mature and popular. When using oily glass baking varnishes, more than 50% of organic solvents (toluene, xylene, industrial alcohol, etc.) need to be added. These solvents are easy to volatilize and irritate It has a strong odor and is poisonous to the human body in varying degrees. During the production process, application process and dr...
