Problems solved by technology

[0003] The existing water-based leather paint color paste has the following disadvantages: 1) In order to make the color paste stable in storage, some water-based resins such as casein are added to enhance the stability of the color paste. The slurry will be limited in application, and sometimes even flocculation and sedimentation will occur due to the compatibility with the application system, making it unusable
2) The pigment content of the resin color paste cannot reach a high level, and the cost performance is not high
3) The application range of the paint color paste is narrow

Abstract

The invention relates to water-based resin-free pigment printing paste and provides pigment printing paste applicable to coloring of water-based leather coatings and pigment printing of pure cotton, polyester cotton and blended fabric. The water-based resin-free pigment printing paste comprises the following components by weight: 2 to 20 percent of wetting agent, 1 to 20 percent of dispersing agent, 1 to 10 percent of stabilizing agent, 25 to 70 percent of pigment and the balance of deionized water, wherein the wetting agent is one of dibasic alcohol or condensed poly diols; the dispersing agent comprises one or more of sodium salt or ammonium salt of an acrylic copolymer and a multi-anchor multi-chain macromolecular polymer; the stabilizing agent comprises one or more of a low-toxicity anti-corrosion bactericide, a defoaming agent and an anti-settling agent. The water-based resin-free pigment printing paste is applicable to coloring of leather coatings and pigment printing of pure cotton, polyester cotton and blended fabric, and is wide in application range; a paint film has high water resistance and high dyeing rate.

Description

technical field [0001] The invention relates to coatings, in particular to a water-based resin-free environment-friendly coating color paste. Background technique [0002] In the production and application of water-based leather paint colorants, the traditional method uses non-ionic surfactants, wetting agents, water-based film-forming resins, water, etc. as carriers to disperse the pigments in the system and process them through physical grinding. It becomes a slurry-like floating substance with a fineness of less than 5 μm. [0003] The existing water-based leather paint color paste has the following disadvantages: 1) In order to make the color paste stable in storage, some water-based resins such as casein are added to enhance the stability of the color paste. The application of slurry will be limited, and sometimes even flocculation and sedimentation will occur due to compatibility problems with the application system, making it unusable. 2) The pigment content of the ...
