[0002] Water-based acrylic color chips are made of high-quality organic pigments, high-grade water-based acrylic resin as a carrier, and the pigments are pre-dispersed in the carrier resin. This series of color chips are used in water-based printing inks and have been used in water-based inks for paper flexographic printing, such as preparation, food and beverage packaging, etc.

[0003] The pigment content of water-based acrylic color chips is up to 65%, and no additives are added, which makes AC water-based color chips give the greatest flexibility in ink formulation in application. They can be directly loaded into the ink formulation or first produced into color paste, and then the color paste is added to the ink in the form of ink oil to produce the required ink with appropriate water-based resin. Water-based acrylic color chips are easy to disperse on high-speed dispersers, give high color concentration and gloss, and are easy to transport and have a long storage time.

[0004] The acid and alkali resistance of the water-based color tablets in the prior art is poor, and the water-based color tablets themselves tend to become fragile after drying, which makes it difficult to take them out for use after drying. In addition, the water-based color tablets soften under high temperatures, which makes them inconvenient to use and may affect the effect. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art that the acid and alkali resistance of water-based color tablets is poor, and the water-based color tablets themselves are prone to become fragile after drying, which makes it more troublesome to take out and use them after drying in the later stage, and the water-based color tablets soften under high temperatures, which is inconvenient to use and may affect the effect, and to propose a water-based color tablet.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] As a further description of the above technical solution:

[0011] Any one of the colors of the pigment may be a combination pigment of multiple colors.

[0012] The method for preparing a water-based color film specifically comprises the following steps:

[0013] S1, putting acrylic resin and butyl rubber into a hot melt pot to melt and stir so that the acrylic resin and butyl rubber can be fully mixed together;

[0014] S2. Add dispersant, aluminum hydroxide and silicon carbide during stirring, and continue heating to fully mix them;

[0015] S3, adding the cement and ointment again and stirring and mixing;

[0016] S4, adding water to the mixed materials, and putting them into a kneading machine for thorough kneading;

[0017] S5. Continue to heat until the acrylic resin and butyl rubber are completely dissolved and mixed with the pigment and then pour out;

[0018] S6, putting the fused material into a ball mill for grinding;

[0019] S7, pouring out the fused material to cool it, and drying it with a dryer to solidify it;

[0020] S8. When the material solidifies, use a slicer to slice it so that it can reach a suitable size and finally reach a qualified color slice.

[0021] As a further description of the above technical solution:

[0022] In S1, the stirring time is controlled to be 30-40 minutes, the heating time is controlled to be the same as the stirring time, and the heating temperature is controlled to be maintained at 80-90°C.
