Environment-friendly watersoluble tintage paint, preparation and uses thereof

Abstract

The invention relates to an environment protective type water coloring coating as well as a preparation method and an application thereof. The water coloring coating consists of the following components and contents (weight portions): 40 to 60 portions of water-base resin; 10 to 25 portions of latent solvent; 20 to 25 portions of de-ionized water; 0 to 3 portions of film forming additive; 0.1 to 2 portions of pH value regulator, 0.1 to 2 portions of scratch-resistant agent; 0.1 to 0.5 portion of wetting agent, 0 to 0.2 portion of rheological controlling agent and 0.05 to 0.2 portion of foam killer. Compared with the prior art, the invention has the advantages of environment protection performance, low production cost and good printing suitability, being incapable of destroying the bottom layer during coating process and avoiding lifting phenomenon generated by solvent coating; and the environment protective type water coloring coating can be directly used for replacing the existing solvent coloring coating through pilot scale production confirmation.

Description

technical field [0001] The invention relates to a coloring paint, in particular to an environment-friendly water-based coloring paint and its preparation method and application. Background technique [0002] A layer of yellow transparent paint is often applied to transfer cardboard or composite cardboard to make the silver card appear like a gold card. [0003] Most of the existing coloring coatings are solvent-based systems, which use a large amount of organic solvents. On the one hand, the high content of volatile organic compounds (VOCs) causes serious pollution to the production and use environment, and on the other hand, there is also the problem of high solvent costs. In addition, there are some transparent water-based coloring paints on the market, but the dye pastes that match them contain a large amount of organic solvents such as esters and glycol ethers, and even the water-based paint itself contains a small amount of similar solvents. [0004] Above-mentioned va...

Problems solved by technology

[0003] Most of the existing coloring coatings are solvent-based systems, and a large amount of organic solvents are used. On the one hand, the high content of volatile organic compounds (VOCs) causes serious pollution to the production and use environment, and on the other hand, there is also the problem of high solvent costs.

In addition, there are also some transparent water-based coloring paints on the market, but the dye pastes that match them contain a large amount of organic solvents such as esters and glycol ethers, and even the water-based paint itself contains a small amount of similar solvents.

[0004] The above factors restrict the application range of colored coatings
