Embodiment 1

[0023] Take 20 parts of Everlasting Red with a balance, 40 parts of s-2916 resin (Oriental Yakeli Company), 36 parts of deionized water, 0.5 part of polyether siloxane copolymer (content 100wt.%), 1.5 parts containing Aqueous copolymer solution of pigment affinity group (concentration: 40wt.%), 2 parts of polysiloxane-polyether copolymer (content: 100wt.%). Pour the above components into the mixing device, stir with a mechanical mixer for 30 minutes to mix them evenly, then pour them into the grinding chamber of a sand mill, grind and disperse them with a sand mill for 100 minutes, and test their particle size, the particle size is less than or equal to 3 microns , stop grinding, if the particle size is greater than 3 microns, continue grinding until the particle size is less than or equal to 3 microns; then check the various indicators and properties of the ink, filter and pack after passing the test, and obtain the ink.

Embodiment 2

[0025] Take 25 parts of permanent red, 37.5 parts of s-2916 resin, 33 parts of deionized water, 1.5 parts of polyether siloxane copolymer, 2 parts of aqueous copolymer solutions containing pigment affinity groups (concentration is 40wt .%), 1 part polysiloxane-polyether copolymer. Pour the above components into the mixing device, stir with a mechanical mixer for 45 minutes to mix them evenly, then pour them into the grinding chamber of the sand mill, grind and disperse them with the sand mill for 90 minutes, and test their particle size, the particle size is less than or equal to 3 microns , stop grinding, if the particle size is greater than 3 microns, continue grinding until the particle size is less than or equal to 3 microns; then check the various indicators and properties of the ink, filter and pack after passing the test, and obtain the ink.

Embodiment 3

[0027] Take 22.5 parts of permanent red, 35 parts of s-2916 resin, 39 parts of deionized water, 1 part of polyether siloxane copolymer, 1 part of aqueous solution of copolymer containing pigment affinity group (concentration is 40wt .%), 1.5 parts of polysiloxane-polyether copolymer. Pour the above components into the mixing device, stir with a mechanical mixer for 30 minutes to mix them evenly, then pour them into the grinding chamber of a sand mill, grind and disperse them with a sand mill for 100 minutes, and test their particle size, the particle size is less than or equal to 3 microns , stop grinding, if the particle size is greater than 3 microns, continue grinding until the particle size is less than or equal to 3 microns; then check the various indicators and properties of the ink, filter and pack after passing the test, and obtain the ink.

Abstract

The invention relates to a pure water gravure magenta ink for tipping paper and a preparation method of the pure water gravure magenta ink and belongs to the technical fields of packaging and printing. The ink comprises the following components in parts by weight: 20-25 parts of a red pigment, 35-40 parts of waterborne acrylic resin, 33-39 parts of deionized water, 0.5-1.5 parts of a defoaming agent, 1-2 parts of a dispersing agent and 1-2 parts of a surfactant. According to the ink, since deionized water is adopted as a solvent and no organic solvent is used, the atmospheric environment pollution is reduced; since the ink is diluted with only deionized water in printing and the stereotype is adopted, the cost is reduced, the safety and environmental friendliness are achieved, the safety indicator VOC detection is in line with GB / T 26395-2011, and the heavy metal detection is in line with EN71-3. The production process of the ink is simple, the flatting property is good, the range of the printing speed is 100-200m per minute and the printability and the printing performance are good.

Description

technical field [0001] The invention relates to a gravure magenta ink for pure water type tipping paper and a preparation method thereof. The ink is a gravure printing ink and belongs to the technical field of packaging and printing. Background technique [0002] Tipping paper, commonly known as tipping paper, is a cigarette packaging material used as the outer packaging of cigarette filter rods. It belongs to special industrial paper. It is usually printed from white tipping base paper. At present, the inks used by many tipping paper printing factories are mostly alcohol-soluble and ester-soluble inks. These ink components contain a large amount of volatile organic solvents, which not only pollute the atmospheric environment, but also use this type of ink to print water. After the paper is loosened, a certain amount of volatile organic solvents will remain on the surface of the tipping paper, which is harmful to human health. With the improvement of people's awareness of e...
