Embodiment 1

[0030] A plastic surface printing ink is characterized in that it is made up of the following raw materials in parts by weight:

[0031] Alcohol-soluble polyamide resin solution 30%

[0032] Nitrocellulose resin solution 5%

[0033] Pigment titanium dioxide 32%

[0034] Filler 5%

[0035] Polyethylene wax 1%

[0036] Erucamide 1.5%

[0037] Auxiliary 0.5%

[0038] Dimethyl phthalate 2%

[0039] Ethyl acetate 30%

[0040] Ethanol 30%

[0041] n-Propyl Acetate 30%

[0042] The alcohol-soluble polyamide resin liquid is made by dissolving liquid polyamide resin by using ethanol and ethyl acetate as solvents, wherein the weight percentage of ethanol is 55%, the weight percentage of ethyl acetate is 30%, and the liquid polyamide resin The weight percentage is 30%, and preferred weight percentage is ethanol 50%, ethyl acetate 25%, liquid polyamide resin 25%;

[0043] Described nitrocellulose resin liquid adopts ethanol, ethyl acetate as solvent, dissolves nitrocellulose and...

Abstract

The invention discloses a plastic surface printing ink. The printing ink comprises the following raw materials in percentages by weight: 20-30% of alcohol-soluble polyamide resin solution, 1-5% of nitrocotton resin solution, 10-32% of pigment titanium dioxide, 1-5% of filler, 0.2-1% ofpolyethylene wax, 0.5-1.5% of erucyl amide, 0.1-0.5% of additive, 1-2% of dimethyl phthalate, 10-30% of ethyl acetate, 10-30% of ethanol and 10-30% n-propyl acetate. The invention takes full advantage of the characteristic that the modified polyamide resin can be dissolved in alcohol, the obtained alcohol-soluble polyamide resin solution effectively forms affinity to nitrocotton resin with a low molecular weight structure and has a good compatibility, so that a good leveling is realized during the printing process and the ink with high solid content can be prepared. The printing viscosity of the ink can be diluted to 12 seconds, the ink is adapted to printing machine speed of above 350 meter per minute, and the production efficiency is improved.

Description

technical field [0001] The invention mainly relates to a technical ink, in particular to a plastic surface printing ink and a preparation method thereof. Background technique [0002] Plastic surface printing ink is applied to the packaging and printing of PE and OPP plastic substrates. After printing on the surface of PE and OPP plastic films, the surface of the ink film does not need to be compounded with a layer of plastic film after film formation. The ink film is completely exposed to the packaging products. Therefore, the requirements for the adhesion fastness of the ink on the plastic surface, the abrasion resistance of the ink film after printing, light fastness, frost resistance, temperature resistance, and health and hygiene are even more important. Because traditional plastic surface printing inks mainly use benzene and ketones as solvents, polyamide resins and nitrocellulose resins are used as ink binders. During its production and application, benzene and k...
