Problems solved by technology

Generally, inks produced by traditional techniques can only adapt to the printing speed of 150~200m / min, and their light resistance and chemical resistance are also poor, and they are prone to yellowing, which can no longer meet the needs of today's production.

Embodiment 1

[0022] White ink is composed of the following components by mass: 8-12 parts of polyamide resin, 0-5 parts of nitrocellulose resin, 30 parts of pigment, 12 parts of ethyl acetate, 12 parts of n-propyl acetate, and 15 parts of isopropanol , 15 parts of ethanol, 0.5 parts of adhesion promoter, 1 part of polyethylene wax powder and 0.5 parts of anti-sticking agent. The nitrocellulose resin is 1 / 8 second nitrocellulose resin, the anti-sticking agent is erucamide, and the pigment is titanium dioxide.

[0023] The present embodiment is formed by following preparation steps:

[0024] 1) Weigh the materials, weigh the required parts by weight according to the formula, and set aside;

[0025] 2) Configure nitrocellulose resin liquid, mix the whole weight of ethyl acetate, n-propyl acetate, isopropanol and ethanol evenly to obtain a mixed solvent, and then take the whole weight of nitrocellulose resin and 4 times the weight of nitrocellulose resin Mixed solvents, mixed and dissolved t...

Embodiment 2

[0031] Color ink, the pigment is selected from one of naphthol magenta, permanent yellow, phthalocyanine blue, carbon black, permanent orange, phthalocyanine green or permanent violet, and the mass parts of each component in the ink are as follows: polyamide 8 parts of resin, 5 parts of nitrocellulose resin, 15 parts of pigment, 15 parts of ethyl acetate, 12 parts of n-propyl acetate, 25 parts of isopropanol, 15 parts of ethanol, 0.5 parts of adhesion promoter, 1 part of polyethylene wax powder And 0.5 parts of anti-sticking agent. The nitrocellulose resin is 1 / 8 second nitrocellulose resin, and the anti-sticking agent is erucamide.

[0032] The ink with the above components was prepared into a finished ink according to the preparation process in Example 1, except that the speed of the disperser in step 3) was changed to 150r / min and 1200r / min in turn.

Embodiment 3

[0034] Color ink, the pigment is selected from one of naphthol magenta, permanent yellow, phthalocyanine blue, carbon black, permanent orange, phthalocyanine green or permanent violet, and the mass parts of each component in the ink are as follows: polyamide 12 parts of resin, 2 parts of nitrocellulose resin, 15 parts of pigment, 15 parts of ethyl acetate, 10 parts of n-propyl acetate, 20 parts of isopropanol, 25 parts of ethanol, 0.5 parts of adhesion promoter, 1 part of polyethylene wax powder And 0.5 parts of anti-sticking agent. The nitrocellulose resin is 1 / 8 second nitrocellulose resin, and the anti-sticking agent is erucamide.

[0035] The ink with the above components was prepared into a finished ink according to the preparation process in Example 1, except that the speed of the disperser in step 5) was changed to 1200r / min.

[0036] The quality indicators of alcohol-soluble high-speed surface printing environmental protection ink in the above-mentioned embodiment are...

Abstract

The invention discloses alcohol-soluble environment-friendly high-speed surface printing ink. The alcohol-soluble environment-friendly high-speed surface printing ink is prepared from the following ingredients in parts by mass: 8-12 parts of polyamide resin, 0-5 parts of nitro-cotton resin, 10-30 parts of pigment, 5-20 parts of ethyl acetate, 5-20 parts of n-propyl acetate, 15-25 parts of isopropanol, 15-30 parts of ethanol, 0.5 part of adhesion promoter, 1 part of polyethylene wax powder and 0.5 part of anti-sticking agent. The ink disclosed by the invention is prepared through the steps of weighing materials, preparing a nitro-cotton resin solution, pre-dispersing, grinding to disperse, adjusting viscosity, carrying out chromatography, filtering and packaging. The ink is higher in fineness, is more uniform, can adapt to the print speed of 300m / min, and is excellent in freezing resistance and anti-adhesion property and good in print effect.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an alcohol-soluble high-speed surface printing environmental protection ink and a preparation method thereof. Background technique [0002] Ink is an important material used for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It consists of pigments, binders, additives and solvents. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration, etc. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. With the development of printing technology and the printing industry's emphasis on production efficiency and energy saving, the domestic printing industry is rapidly developing into the f...
