Embodiment 1

[0068] Prepare the following raw materials: 320 grams of alcohol-soluble polyurethane resin, 10 grams of polyvinyl butyral resin, 10 grams of matte powder, 300 grams of titanium dioxide, 170 grams of ethanol, and 190 grams of ethyl acetate. In the alcohol-soluble polyurethane resin solution, by weight percentage, the polyurethane resin content is 35%, the ethanol content is 45%, and the ethyl acetate content is 20%.

[0069] Then mix ethanol, ethyl acetate and polyvinyl butyral resin, stir at a high speed to dissolve completely, add titanium dioxide and matte powder to disperse, grind to make the fineness below 15 μm, and then prepare 1000 grams of white printing ink.

[0070] Mass production is equipped with production according to the above ratio.

Embodiment 2

[0072] Prepare the following raw materials: 300 grams of alcohol-soluble polyurethane resin, 25 grams of polyvinyl butyral resin, 10 grams of matte powder, 100 grams of carbon black, 360 grams of ethanol, and 205 grams of ethyl acetate. In this alcohol-soluble polyurethane resin liquid, by weight percentage, the polyurethane resin content is 33%, the ethanol content is 47%, and the ethyl acetate content is 20%.

[0073] Then mix ethanol, ethyl acetate and polyvinyl butyral resin, stir at high speed to make it completely dissolved, add carbon black and matte powder to disperse, grind to make the fineness below 15 μm, and obtain 1000 grams of black printing ink.

[0074] Mass production is equipped with production according to the above ratio.

Embodiment 3

[0076] Prepare the following raw materials: 300 grams of alcohol-soluble polyurethane resin, 20 grams of polyvinyl butyral resin, 10 grams of matte powder, 100 grams of phthalocyanine blue, 360 grams of ethanol, and 210 grams of ethyl acetate. In this alcohol-soluble polyurethane resin solution, by weight percentage, the polyurethane resin content is 33%, the ethanol content is 45%, and the ethyl acetate content is 22%.

[0077] Then mix ethanol, ethyl acetate and polyvinyl butyral resin, stir at a high speed to dissolve completely, add phthalocyanine blue pigment and matte powder to disperse, grind to make the fineness below 15 μm, and then obtain 1000 grams of blue printing ink.

[0078] Mass production is equipped with production according to the above ratio.

Abstract

The invention discloses an alcohol-dissoluble polyurethane resin compound printing ink and a preparation method thereof. The printing ink is prepared by processing the following components by weight percent: 25-35% of alcohol-dissoluble polyurethane resin liquor, 1-3% of polyvinyl butyral resin, 1% of extinction powder, 8-33% of pigment, 0-0.5% of an adhesion reinforcing agent, 15-40% of ethanol and 15-25% of ethyl acetate; and polyurethane resin in the alcohol-dissoluble polyurethane resin liquor accounts for 30-35% by weight percent. The printing ink has the advantages of environmental friendliness, safety, wide application scope, good thermal stability and the like.

Description

technical field [0001] The invention relates to the field of ink printing and dyeing, in particular to an alcohol-soluble polyurethane resin composite ink and a manufacturing method thereof. Background technique [0002] my country's plastic gravure printing ink has a development history of more than 30 years. Among them, the chlorinated polypropylene ink produced since the early 1980s is the most widely used inner printing composite ink, accounting for half of the food packaging and printing. However, this type of ink has insurmountable shortcomings, which deviates from people's increasing requirements for food safety and environmental protection, and will gradually reduce its market share until it exits the stage of history: [0003] a: Non-environmental protection of chlorinated polypropylene resin system: [0004] 1) In the production process of chlorinated polypropylene resin, the carbon tetrachloride used is a prohibited substance in the "Stockholm Convention on Per...
