Abstract

The invention relates to water-based metal package barrel color paint and a preparing method of the color paint. The color paint comprises deep color paint and light color paint, wherein the light color paint is prepared from the following ingredients in parts by weight: deionized water, defoaming agents, dispersing agents, water dilution polyester resin, titanium dioxide, permanent yellow, precipitated barium sulphate, water-based organic silicon flatting agents, flash-rust inhibitors and water-based amino resin, and the deep color paint is prepared from the following ingredients in parts by weight: deionized water, defoaming agents, dispersing agents, water dilution polyester resin, precipitated barium sulphate, titanium dioxide, either phthalocyanine blue or phthalocyanine green, water-based crylic acid flatting agents, flash-rust inhibitors and water-based amino resin. The paint adopts water as the diluent, any organic solvent is not added, the petroleum resources are saved, the atmospheric emission is reduced, the ecological environment is protected, and the harm to human bodies is avoided.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based color separation paint for metal packaging barrels and a preparation method thereof. technical background [0002] At present, most color separation paints for metal packaging barrels on the market use solvent-based paints, which contain a large amount of volatile organic compounds (VOC). These organic compounds mainly contain benzene, toluene, xylene, etc., which cause great harm to the human body. Going into the atmosphere will not only cause a waste of resources, but also cause serious pollution to the atmosphere. With the improvement of people's awareness of environmental protection, the country's requirements for environmental protection are becoming increasingly stringent, and the development of low-VOC or even zero-VOC water-based environmentally friendly coatings is an inevitable development direction. [0003] To develop water-based color-separation paint for metal...
