Problems solved by technology

[0003] The existing domestic color steel plate coatings are mainly solvent-based, and a large amount of organic solvents are added during production, which has problems such as high volatile organic content, strong odor, and environmental pollution.
Sometimes it even harms the painting workers, and some color steel paints even release volatile organic compounds for a long time
In addition, after the existing color steel paint is used outdoors for a long time, it is affected by the aging effect of ultraviolet radiation, resulting in a decline in impact resistance, weather resistance, salt spray resistance, adhesion, hardness, etc.

Abstract

The invention provides environment-friendly waterborne colored steel paint and a preparing method thereof. The environment-friendly waterborne colored steel paint is prepared from, by mass, 10.0-15.0%of waterborne epoxy ester resin, 32.0-55.0% of waterborne acrylic acid polymer emulsion, 0.25-0.75% of antifoaming agent, 0.5-1.25% of dispersing agent, 0.88-1.63% of neutralizer, 0.31-0.79% of wetting agent, 4.51-7.39% of coalescing agent, 0.35-0.93% of drier, 2.23-4.36% of organic pigment, 0.63-1.77% of titanium dioxide, 2.22-4.69% of composite zinc phosphate, 4.31-5.57% of anti-setting thixotropic agent, 0.43-1.37% of medium chrome yellow, 2.43-3.27% of barium sulfate, 0.63-1.67% of anti-flash rusty retardant agent, 0.32-0.88% of thickening agent and 15.0-25.0% of deionized water. The environment-friendly waterborne colored steel paint is prepared from waterborne materials, the dose of organic solvent is reduced, and the proportion of the content of volatile organic compounds to the content of the total paint in the environment-friendly waterborne colored steel paint is lower than that in traditional paint. A mixed system of waterborne acrylic acid polymer emulsion and waterborne epoxy ester resin is adopted, the covering capability can be improved, a coating with high rigidity, high adhesion and high shock resistance is obtained, the sunscreen capability of the environment-friendly waterborne colored steel paint is improved, and the product performance is more excellent.

Description

technical field [0001] The invention relates to an environment-friendly water-based paint for color steel plates and a preparation method thereof, which are used in the field of paints. Background technique [0002] Color steel plate refers to color coated steel plate, which is a kind of steel plate with organic coating, which can be divided into veneer, color steel composite plate, floor bearing plate and so on. Widely used in walls and roofs of large public buildings, public workshops, prefabricated houses and integrated houses. Its basic features are: light weight, heat insulation, high strength and flexible installation. In the 1980s, my country began to build color steel plate units one after another. By 2000, domestic color steel plates had reached 1.73 million tons. With the rapid rise of the color steel plate industry, while driving the development of the color steel plate industry, it also drives the development of its related coating industry. According to the u...
