Problems solved by technology

The packaging plastic film adopts multi-layer composite method and composite aluminized material to meet this demand. The ink is to give a picture, text and description on the surface of the package, and it is a coating between various substrates to prevent the ink from damaging the substrate. Corrosiveness, ordinary ink uses pigments as coloring agents, which have a certain covering power, hinder the penetration of light, have low transparency, and cannot clearly show the metallic luster of the aluminum-plated substrate, thus greatly affecting the appearance of packaging products Aesthetics

Embodiment 1

[0041] Preparation:

[0042] a) Dye dilution process: Dilute the dye into a solution with a weight concentration of 20% with an appropriate amount of mixed solvent, and adjust the pH value of the solution to 7.0, leave it to stand and filter, and the mixed solvent is ethyl acetate, Ethanol, isopropanol, propylene glycol methyl ether, the weight ratio is 1:1.8:1:0.4;

[0043] b) Resin dilution process: Dilute the vinyl chloride vinyl acetate copolymer resin to a weight concentration of 20% and the modified chlorinated polypropylene resin to a weight concentration of 50% with the same mixed solvent as the a) operation; this ratio The mixed solvent can fully dissolve the vinyl chloride vinyl acetate copolymer resin under the condition that the amount of the mixed solvent is the least, and reduce the pollution of the solvent to the environment.

[0044] c) Blending process: first stir the remaining mixed solvent in the formula with polyurethane solution, vinyl chloride vinyl acet...

Abstract

The invention discloses a gravure ink and a preparation method thereof. The ink consists of the following substances of modified polyurethane, a vinyl chloride acetic acid copolymer resin, a modified chlorinatedpolypropylene resin, a dye, an erucidic acid amide wax, an antifoaming agent, an adhesion promoter, propylene glycol methyl ether, acetic ether, ethanol and dimethyl carbinol. The preparation method of the invention includes the following sequential working procedures: a) the dye diluting; b) the resin diluting; c) the blending. Compared with the present technology, the invention is low in solvent residue, and printing products have no version fogs of knife wires with very good adhesion fastness on BOPP and PET and are especially suitable for package printing of PET aluminium-plated products. Metallic lustre of composite packaged products is fully shown, and the visual effect is very good and the adhesion fastness of the ink is equal to or more than 98 percent. The composite sealing strength is 45N per 15mm.

Description

technical field [0001] The invention relates to a gravure ink and a preparation method thereof, in particular to a gravure transparent ink and a preparation method thereof. Background technique [0002] Plastic film packaging products are very common in daily life. Plastic film packaging products include pharmaceutical packaging, food packaging, and daily chemical packaging. [0003] The characteristics of packaging requirements for plastic film packaging are anti-corrosion, anti-leakage, anti-oxidation, better sealing and air tightness, which is more conducive to the protection of packaging. The packaging plastic film adopts multi-layer composite method and composite aluminized material to meet this demand. The ink is to give a picture, text and description on the surface of the package, and it is a coating between various substrates to prevent the ink from damaging the substrate. Corrosiveness, ordinary inks use pigments as colorants, which have a certain covering power,...
