Abstract

The invention discloses special water-based paint for containers. The water-based paint is prepared from the following components in parts by weight: 40-50 parts of aqueous acrylic emulsion, 8-12 parts of deionized water, 0.5-0.9 parts of an antifreezing agent, 0.4-0.6 parts of a neutralizing agent, 0.5-1.5 parts of a dispersing agent, 0.1-0.3 parts of a defoamer, 3-7 parts of a film forming aid,0.05-0.15 parts of a bactericide, 4-6 parts of pigment, 0.5-1.5 parts of a flash rust inhibitor, 0.4-0.6 parts of a wetting and leveling agent, 2-4 parts of a dust-proof thixotropic agent and 2-4 parts of a thickening agent. The invention also discloses a preparation method. The special water-based paint for the containers can solve the problems of floating of traditional paint when the paint is constructed on silicone adhesives over and over again and poorer adhesion and water resistance of traditional water-based paint on galvanized plates.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special water-based paint for containers and a preparation method thereof. Background technique [0002] my country is a big container manufacturing country, so there is a large demand for water-based anti-corrosion coatings for containers. Although container coatings have strong anti-corrosion performance and good construction performance, they are prone to generate a large amount of VOC during construction. Therefore, low-VOC water-based container coatings have been promoted. In addition, container coatings require a higher dry film thickness in one construction, better anti-corrosion performance and quick drying, and excellent weather resistance and wear resistance. [0003] Generally, the main material of the container is galvanized sheet, etc., because the bonding of galvanized sheet needs to be bonded with silicone glue, and the traditional paint often blooms when it i...
