Problems solved by technology

[0003] Aluminum foil ink can be divided into two categories: solvent-based and water-soluble. Among them, the disadvantages of the water-soluble aluminum foil ink in the prior art are: slow drying speed, poor water resistance, unsatisfactory softness, and water-based aluminum foil ink. Stiffness after printing Not enough, the requirements for the packaging machine are relatively high, and the printed paper is relatively soft
Although solvent-based aluminum foil inks in the prior art can effectively solve the above-mentioned shortcomings of water-soluble aluminum foil inks, some solvent-based aluminum foils use stupid or some high-boiling point ester alcohols as dilution solvents in the preparation process, and these high-boiling point esters Alcohols and alcohols are difficult to volatilize. After the finished ink is printed, the volatilization speed of toxic substances is slow, and the residual amount after volatilization does not meet the national standard, which is harmful to human health.

Abstract

The invention belongs to the field of ink printing and particularly relates to a method for preparing an aluminum foil ink. The method includes steps of: preparing ternary chloroacetate resin solution; preparing acrylic resin solution; preparing polyketone resin solution; mixing the three resin solutions and obtaining a macromolecule resin mixing solution, uniformly mixing the 15%-35% of macromolecule resin mixing solution, 0%-25% of dye, 35-70% of organic solvent and 1-10% of assistant by weight percentage and obtaining the aluminum foil ink. Compared with the prior art, the aluminum foil ink produced by the method has the advantages of slight smell, strong adhesion, excellent weathering resistance, good water, friction and crumpling resistance, high grade of transparency, high gloss, good levelability and strong transitivity and can adapt to various low and high-speed machines. The solvent of the ink can be volatilized quickly. The process for preparing the ink is simple, and the ink is low in cost and is very suitable for the large-scale industrial production.

Description

technical field [0001] The invention relates to the field of ink printing, in particular to a preparation method of aluminum foil ink. Background technique [0002] The printed products using aluminum foil ink have original and natural metallic texture, and the brightness and eye-catching are higher than any other substrates. Aluminum foil ink is widely used in the printing of food packaging such as beer labels and candy packaging, so it may have certain contact with food Therefore, it is required that the printed products are non-toxic and harmless, or that the residual substances are less harmful and will not affect people's health. [0003] Aluminum foil ink can be divided into two categories: solvent-based and water-soluble. Among them, the disadvantages of the water-soluble aluminum foil ink in the prior art are: slow drying speed, poor water resistance, unsatisfactory softness, and water-based aluminum foil ink. Stiffness after printing Not enough, the requirements fo...
