Embodiment 1

[0016] Prepare the following raw materials first: 280 grams of ester and alcohol-soluble polyurethane resin, 35 grams of vinyl acetate resin, 300 grams of titanium dioxide, 275 grams of propyl acetate, 90 grams of isopropanol, and 20 grams of ethyl acetate; In the polyurethane resin liquid, by weight percentage, the polyurethane resin content is 35%, the propyl acetate content is 60%, and the isopropanol content is 5%;

[0017] Then mix the raw materials, stir at high speed to completely dissolve the vinyl acetate resin and fully mix the raw materials, then grind to make the fineness below 15 microns, and then obtain 1000 grams of white printing ink.

[0018] Raw materials are allocated according to the above ratio during mass production.

Embodiment 2

[0020] Prepare the following raw materials first: 300 grams of ester and alcohol-soluble polyurethane resin solution, 30 grams of vinyl acetate resin, 330 grams of titanium dioxide, 270 grams of propyl acetate, and 70 grams of isopropanol; in this ester and alcohol-soluble polyurethane resin solution, press In terms of weight percentage, the polyurethane resin content is 36%, the propyl acetate content is 59%, and the isopropanol content is 5%.

[0021] Then mix the raw materials, stir at high speed to completely dissolve the vinyl acetate resin and fully mix the raw materials, then grind to make the fineness below 15 microns, and then obtain 1000 grams of white printing ink.

[0022] Raw materials are allocated according to the above ratio during mass production.

Embodiment 3

[0024] Prepare the following raw materials first: 300 grams of ester and alcohol-soluble polyurethane resin, 30 grams of vinyl acetate resin, 100 grams of carbon black, 420 grams of propyl acetate, 120 grams of isopropanol, and 30 grams of ethyl acetate; In the polyurethane resin liquid, by weight percentage, the polyurethane resin content is 35%, the propyl acetate content is 60%, and the isopropanol content is 5%;

[0025] Then each raw material is mixed, and then high-speed stirring is made to dissolve the vinyl acetate resin completely and each raw material is fully mixed, and then grinds so that the fineness reaches below 15 microns, promptly makes 1000 grams of black printing inks.

[0026] Raw materials are allocated according to the above ratio during mass production.

Abstract

A print ink contains ester, alcohol solution of polyurethane resin, chloroacetate resin, pigment, propyl acetate, iso-proparol and ethyl acetate. Its advantages are high print effect, low poison and no damage to human body.

Description

technical field [0001] This invention relates to inks for printing. Background technique [0002] Some of the existing printing inks have poor printing adaptability, and may have inconsistent use effects due to different conditions such as seasons, humidity, and temperature. Some inks contain highly toxic organic solvents, such as benzene and ketone solvents (such as toluene, methyl ethyl ketone, etc.). When the solvents are not handled properly during the ink production process, it is easy to cause harm to the bodies of ink production workers; The evaporation of the highly toxic solvent contained in the ink will also cause certain harm to the body of the printing workers; due to a certain amount of solvent remaining on the printed matter, these solvents will produce peculiar smell and affect the health of the printed matter user. Contents of the invention [0003] The object of the present invention is to provide a printing ink with good printing adaptability and low tox...
