Problems solved by technology

A well-known flexible packaging company in China informed that the recovered mixed solvents will be outsourced for processing, and then repurchased at 80% of the original price. However, the imbalance between supply and demand caused by the large number of recovered solvents and the small number of distillation units will inevitably affect the price. The law of the market is still understood. For printing companies that are already in a state of low profit, this cost cannot be ignored

Embodiment 1

[0025] In the present embodiment, the single-component solvent ink of the present invention is composed of the following mass fractions: 15 parts of chloroether resin, 1 part of cellulose acetate butyrate, 0.3 parts of polyethylene wax powder, and 13 parts of pigment red , 70.7 parts of solvent. Among them, the chloroether resin is a polymer of vinyl chloride and vinyl isobutyl ether, cellulose acetate butyrate is a cellulose ester formed by the co-esterification of hydroxyl groups in cellulose molecules with acetic acid and butyric acid, and the solvent is 100% of n-propyl acetate.

[0026] The single-component solvent ink of the above-mentioned components is prepared by the following steps:

[0027] 1) Weigh the material, take the material of the required parts by weight according to the formula, and set aside;

[0028] 2) Pre-dispersion, add 45 parts of n-propyl acetate into the pre-mixing dispersing tank, turn on the dispersing machine and turn all the chlorinated ether ...

Embodiment 2

[0033] In an embodiment, the single-component solvent ink of the present invention is composed of the following mass fractions: 13.5 parts of chloroether resin, 1 part of cellulose acetate butyrate, 0.5 part of polyethylene wax powder, and pigment yellow A7.5 Parts, 4 parts of Pigment Yellow B, 73.5 parts of solvent.

[0034] Among them, the chloroether resin is a polymer of vinyl chloride and vinyl isobutyl ether, cellulose acetate butyrate is a cellulose ester formed by the co-esterification of hydroxyl groups in cellulose molecules with acetic acid and butyric acid, and the solvent is 100% of n-propyl acetate.

[0035] The single-component solvent ink of the above-mentioned composition is prepared into a finished ink according to the preparation process of Example 1, except that the dispersant rotating speed in step 2) is changed to 300r / min and 450r / min successively, and the remaining conditions are the same as in Example 1 .

Embodiment 3

[0037] In an embodiment, the single-component solvent ink of the present invention is composed of the following mass fractions: 13.5 parts of chloroether resin, 0.75 part of cellulose acetate butyrate, 0.5 part of polyethylene wax powder, 3.2 parts of pigment green, 7 parts of pigment yellow, 4.5 parts of pigment blue, 0.3 parts of pigment red, and 73.5 parts of solvent. Among them, the chloroether resin is a polymer of vinyl chloride and vinyl isobutyl ether, cellulose acetate butyrate is a cellulose ester formed by the co-esterification of hydroxyl groups in cellulose molecules with acetic acid and butyric acid, and the solvent is 100% of n-propyl acetate.

[0038] The single-component solvent ink with the above components was prepared into a finished ink according to the preparation process of Example 1.

[0039] The quality index of single solvent component ink in the above-mentioned embodiment is as follows:

[0040]

Abstract

The invention discloses single-component solvent ink and a preparation method thereof. The ink consists of the following components in parts by mass: 12-17 parts of a chloric ether resin, 0.75-1 partof cellulose acetate butyrate, 0.3-0.5 part of polyethylene wax powder, 10-15 parts of a pigment and 65-75 parts of a solvent. The preparation method of the ink with the components comprises the following steps: weighing materials, performing pre-dispersion, performing grinding and dispersion, adjusting the viscosity, and performing filtering and packaging. According to the ink, n-propyl acetate is adopted as a single solvent, the solvent is high in reuse rate after being recycled, and thus relatively low environment protection cost is needed; the ink is relatively good in adhesion property for materials such as PVC, PET and PETG, and relatively good in universality; the ink is relatively good in gloss, relatively good in printing effect, relatively good in shallow net transferring and relatively good in printing adaptability.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a single-component solvent ink and a preparation method thereof. Background technique [0002] In the past 10 years, gravure solvent printing inks have progressed from toluene-based solvents to benzo- and ketone-free alcohol-ester solvents, but the pollution of VOCs to the environment cannot be avoided. From February 2015, the state will exempt 4% consumption tax on coatings with a volatile organic compound (VOCs) content of less than 420 g / L under construction. In March of the same year, Shanghai promulgated the "Printing Industry Air Pollutant Emission Standard ", requiring solvent-based gravure inks to have a VOCs content limit of no more than 800g / kg in the ready-to-use state. The requirements for emission standards are becoming more and more stringent, which requires printing companies to consider various aspects and take countermeasures. [0003] In order to reduce the emissio...
