Embodiment 1

[0022] A kind of vegetable oil-based environmental protection printing ink, calculated by 100kg, comprises following composition and is prepared from:

[0023] Rosin modified phenolic resin 28kg, using high structure, medium and low solubility, low viscosity, high softening point rosin modified phenolic resin, increasing the solid resin content to improve the fixing speed of ink, the softening point of the resin is 180 ~ 200 ℃;

[0024] Vegetable oil 27kg, the vegetable oil is a dry vegetable oil, using black mountain grass seed oil with high iodine value, which can give the ink a very fast drying speed, and its solubility is better than that of linseed oil, soybean oil, tung oil, etc.;

[0025] Solvent 12kg, selects black mountain grass seed oil derivatives for use, such as black mountain grass seed oil methyl ester;

[0026] Pigment and filler 25kg, wherein, the mass ratio of pigment and filler is 4:1; Described pigment can select magenta, phthalocyanine blue B, benzidine ye...

Embodiment 2

[0029] A kind of vegetable oil-based environmental protection printing ink, calculated by 100kg, comprises following composition and is prepared from:

[0030] Rosin-modified phenolic resin 30kg, using high-structure, medium-low solubility, low viscosity, high softening point rosin-modified phenolic resin, increasing the solid resin content to improve the fixing speed of the ink, the softening point of the resin is 180-200°C;

[0031] Vegetable oil 30kg, the vegetable oil is a dry vegetable oil, using black mountain grass seed oil with high iodine value, which can give the ink a very fast drying speed, and its solubility is better than that of linseed oil, soybean oil, tung oil, etc.;

[0032] Solvent 15kg, selects black mountain grass seed oil derivative for use, such as black mountain grass seed oil ethyl ester,

[0033] Pigment and filler 20kg, wherein, the mass ratio of pigment and filler is 5:2; Said pigment can select magenta, phthalocyanine blue B, benzidine yellow or p...

Embodiment 3

[0037] The difference from Example 1 is that the solvent is selected from black lily seed oil butyl ester.

[0038] The preparation method of the vegetable oil-based environmental protection ink in any of the above-mentioned embodiments comprises the following preparation steps:

[0039] (1) Put the rosin-modified phenolic resin, black mountain grass seed oil, solvent, and gel into the reaction kettle, and protect the liquid surface with an inert gas. The inert gas is argon, and the gas pressure is controlled at 0-5MPa. Exclude the air in the reaction kettle, then raise the temperature to 180~200°C, start stirring, and the stirring time is 30min;

[0040] (2) Then cool down to 80°C, put in fillers and pigments, stir for 10 minutes, add additives, and stir for another 30 minutes;

[0041] (3) Put the material obtained in step (2) into a three-roll mill for grinding, pass through a 10 μm filter membrane, check the ink index, adjust to pass, and finally pack and seal.

Abstract

The invention discloses vegetable oil-based environment-friendly ink. The vegetable oil-based environment-friendly ink is prepared from the following components in percentage by mass: 28-35% of rosinmodified phenolic resin, 25-30% of vegetable oil, 10-15% of a solvent, 0.5-1% of gel, 20-25% of pigment and filler and 5-8% of an assistant, wherein the total amount is 100%. The vegetable oil is hedyotis diffusa seed oil; the solvent is hedyotis diffusa seed oil methyl ester, hedyotis diffusa seed oil ethyl ester or hedyotis diffusa seed oil butyl ester. According to the vegetable oil-based environment-friendly ink and the preparation method thereof, the hedyotis diffusa seed oil with high dissolving capacity is used as vegetable oil, the hedyotis diffusa seed oil derivative is used as a solvent, and the drier, the filler and the like are reasonably selected and used, so that the fixation time and the drying and film-forming time of the ink are effectively shortened; in addition, the inkprovided by the invention also realizes zero emission of VOC, and is safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a vegetable oil-based environmentally friendly ink and a preparation method thereof. Background technique [0002] Vegetable oil-based environmentally friendly inks use vegetable oil as a binder. Vegetable oil binders mainly include soybean oil, rapeseed oil and sunflower oil. The advantages of vegetable oil binders are: it can reduce the release of volatile organic compounds, completely remove the hydrocarbon resins in ordinary inks, reduce the content of aromatic hydrocarbons, and have no harm to the human body. [0003] Vegetable oil-based environmentally friendly inks have a wide range of applications, and can be applied to various trademarks, newspapers, magazines, self-adhesive labels, beverages, wine, medicines, etc. Printing of various cosmetics. In addition, the vegetable oil-based environmentally friendly ink will not cause triboelectric charging and can also emit natur...
