Environment-friendly gravure plastic film table-printing ink and preparation method thereof

Abstract

The invention discloses an environment-friendly gravure plastic film table-printing ink and a preparation method thereof. The gravure plastic film table-printing ink is prepared from the following raw materials in parts by weight: 35-40 parts of alcohol ester dissolved polyamide binder, 8-26 parts of a toner, 4-8 parts of an aid, 8-16 parts of functional resin and 30-40 parts of a solvent, wherein the alcohol ester dissolved polyamide binder is prepared from polyamide resin, absolute ethyl alcohol, isopropanol, acetic ether and normal propyl acetate through stirring, heating and emulsification. By utilizing the resin with alcohol ester dissolvability, the gravure plastic film table-printing ink is totally different from traditional table-printing ink, and alcohols and esters are used as the solvent, so that the working environment is improved, and the quality safety of the printing is guaranteed. The gravure plastic film table-printing ink has the beneficial effects that the smell is small, the damage to the environment and the injury to operators are tiny, the environmental influence is relatively low, the preparation method is simple and reasonable, the production efficiency is improved, and the application prospect is wide.

Description

technical field [0001] The invention relates to the field of gravure surface printing ink, in particular to an environment-friendly gravure plastic film surface printing ink and a preparation method thereof. Background technique [0002] Gravure surface printing ink, also known as gravure printing ink, is a general term for various gravure inks used in various gravure printing methods. A type of ink suitable for gravure printing. During printing, the part of the pattern that is concave on the layout is inked, and the ink on the non-pattern part is wiped off or scraped off, and then printed. [0003] At present, the gravure high-temperature-resistant ink for flexible packaging used in daily necessities uses nitrocellulose (NC) and amino resin as binders. This ink is suitable for medicine bags. -130°C); there are also inks with acrylic resin and nitrocellulose as binders, which are suitable for gravure food paper, CPP and PE film packaging, and printed products can withstand ...

[0003] At present, the gravure high-temperature-resistant ink for flexible packaging used in daily necessities uses nitrocellulose (NC) and amino resin as binders. This ink is suitable for medicine bags. -130°C); there are also inks with acrylic resin and nitrocellulose as binders, which are suitable for gravure food paper, CPP and PE film packaging, and printed products can withstand high temperature sealing at 180°C; there are also inks with acrylic resin, Vinyl resin is used as the binder ink, which can withstand high temperature without fading; however, these gravure plastic film surface printing inks are of poor quality and easily pollute the environment
