Abstract

The invention relates to the technical field of water-base paint and a preparation method thereof, in particular to a decorative water-base modified acrylic acid two-component plastic paint mainly used for plastic substrates, such as household electric appliances, toys, automobile interior decoration, etc. and a preparation method thereof; the mass percentage of the raw materials of the water-base modified acrylic acid two-component plastic paint is as below: water-base hydroxyl functional acrylic acid resin: 40 percent to 50 percent; water-base polyester resin: 10 percent to 20 percent; glycol butyl ether acetate: 5 percent to 6 percent; water: 15 percent to 30 percent; DMEA: 0.5 percent to 1 percent; water-base wax emulsion: 1 percent to 5 percent; water-base defoamer: 0.1 percent to 0.5 percent; water-base substrate wetting agent: 0.1 percent to 0.5 percent; thickener: 1 percent to 6 percent; water-base pigment concentrates: 1 percent to 8 percent; the sum of all the components is equal to 100 percent; during use, a curing agent accounting for 20 percent of the total mass of the two types of resin is further added in, which solves the problems of harmful residual and poor flow and leveling of the water-base paint after being used existing in most of the prior solvent-type paints.

Description

technical field [0001] The invention relates to the technical field of water-based coatings and preparation methods thereof, in particular to a water-based modified acrylic two-component plastic coating mainly used for decoration of plastic substrates such as household appliances, toys, and automobile interior decorations and a preparation method thereof. Background technique [0002] At present, the coatings used in the decoration of plastic substrates such as home appliances, toys, and automotive interiors in my country are almost all solvent-based coatings. With the progress of society, the environmental protection regulations of various countries have imposed strict restrictions on the emission of volatile organic compounds (VOC), the content of harmful solvents and various heavy metals. Europe promulgated the VOC Directive, which was adopted by the EU Environment Committee in March 1999, and was added to the national regulations of each EU member state. Commonly used s...
