Abstract

The invention discloses a water-based paint for a wine bottle cap. The water-based paint is characterized by comprising the following components in percentage by weight: 40-45% of water-based polyester resin, 6-10% of a water-based cross-linking agent, 0.2-0.4% of a water-based defoamer, 0.2-0.3% of a water-based leveling agent, 0.4-0.8% of a water-based wetting agent, 1-3% of a PH value neutralizer, 1-3% of a water-based adhesive agent, 3-5% of water-based epoxy resin, 25-30% of rutile titanium dioxide and 8-15% of purified water. The water-based paint has the advantages of reducing atmospheric pollution, being rich in environmental protection and being suitable for wine bottle caps; the invention also discloses a preparation method of the water-based paint, and the water-based is easy toimplement.

Description

technical field [0001] The invention relates to the technical field of fine chemical coatings, in particular to a sheet water-based coating used for roller coating of aluminum plates and a preparation method thereof. The coating is suitable for producing various wine bottle caps. Background technique [0002] At present, the widely used screw wine bottle caps use oil-based paints for both the outer and inner coatings. During the coating and baking process, the VOC emissions are basically greater than 100 g / L, which pollutes the environment and affects operators. In good health. [0003] Water-based paint is applied on the aluminum plate, and pure water is used for dilution and cleaning, which is beneficial to environmental protection. Contents of the invention [0004] The purpose of the invention is to reduce air pollution and provide an environmental-friendly water-based paint suitable for wine bottle caps. [0005] Another object of the present invention is to provide...
