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.
