Embodiment
[0026] A preparation method of environment-friendly cola red double PE ink comprises the following steps:
[0027] (1) prepare resin oil,
[0028] Resin oil is obtained by amination reaction of combined resin with solvent and auxiliary agent,
[0029] Among them, the combination resin is acrylic resin and auxiliary resin, the auxiliary resin is modified polyurethane resin, modified alkyd resin, CAB, polyamide resin and aldehyde and ketone resin, the auxiliary agent is defoamer, single alcohol amine, and the solvent is ionized water,
[0030] The mass percent of above-mentioned components is:
[0031] Acrylic resin (BASFJ-678): 23%
[0032] Modified Polyurethane Resin (MB–2952): 4%
[0033] Modified alkyd resin (WST-1180): 4%
[0034] CAB (Eastman 381-0.5): 3%
[0035] Polyamide resin (BASFPA66-A3GET): 3%
[0036] CK aldehyde and ketone resin (CK-61): 2%
[0037] Defoamer (DF-1181): 0.5%
[0038] Single alcohol amine (BASFGY-14GL0153): 3%
[0039] Deionized water: 57....

Abstract
The invention discloses an environment-friendly coca-red double-PE ink and a preparation method thereof, and belongs to the technical field of printing ink. The preparation method of the ink comprises the following steps: firstly, performing amination reaction on composite resin, solvent and additives to obtain resin oil; then grinding the obtained resin oil, red pigment, additives, water and ethanol by a machine after dispersing and mixing, to obtain color paste; finally, adding composite emulsion, composite resin liquid, color paste and adjuvant, mixing uniformly, adjusting the viscosity, and filtering to obtain the product. According to the invention, the environment-friendly coca-red double-PE ink is featured with no toxicity, no irritant smell, non-corrosiveness, incombustibility and non-explosion, excellent use safety, stable performance, long storage time, good adhesion fastness, fast drying speed, water resistance, alkali resistance, ethanol resistance and the like; the ink is further featured with excellent heat resistance and wear resistance, high color concentration, high color saturation and bright color; and the ink is good in printability, so that the patterns and fonts do not fade or fall off after printing.
Description
technical field [0001] The invention relates to the technical field of inks, in particular to an environment-friendly cola red double PE ink and a preparation method thereof. Background technique [0002] Double PE ink is a new type of ink that uses water (40% to 50%) as a solvent, is non-toxic, has no irritating odor, and is non-flammable and non-explosive. It does not contain volatile organic solvents, which greatly reduces the emission of volatile organic compounds (VOC), thereby reducing air pollution, improving the environment of printing operations, and benefiting the health of employees. Double PE ink can completely eliminate certain toxic and harmful substances in solvent-based inks, eliminate the harm to the human body and the pollution to the packaged goods, especially suitable for tobacco, alcohol, food, beverages, medicines, children's toys and other strict hygienic conditions. Packaging and printing products. In addition, it can not only reduce fire hazards an...
