Example Embodiment

[0016] The main material used in the composite ink of this scheme is benzene-free and ketone-free polyurethane resin. When the residue is detected, it does not contain halogen and heavy metals after testing, which meets environmental protection requirements. In addition, the solubility of polyurethane resin is good, and the solubility of benzene-free and ketone-free polyurethane resin is good, which can fully improve the ink reconstitution performance. After the printing ink is diluted by 10%, the printing can reach the concentration of other existing inks, and the customer's printing transfer rate is increased by 10% , Reflects a more excellent shallow screen printing effect. In addition, using distilled water as a slow-drying auxiliary, the ink printing residue does not contain polymer solvents, and the total printing residue is controlled at 2 mg / square, which fully meets the GT-9685 national testing standard.

Abstract

The invention relates to a composite ink and a preparation method thereof. The composite ink is prepared by mass percentages, and comprises: polyurethane resin ingredient A, urethane resin ingredient B and cross-linking auxiliaries, wherein the polyurethane resin ingredient A is prepared from, 10-30% of no benzene, no ketone-polyurethane resin, 1-10% of UK resin, 1-20% of pigments, 0.5-5% of wax powder, 10-30% of propyl acetate, 1-20% of propyl alcohol; the urethane resin ingredient B is prepared from, 1-20% of no benzene, no ketone-polyurethane resin, 5-25% of ethyl acetate, 1-10% of anhydrous ethanol and 1-6% of distilled water mixture; the cross-linking auxiliaries include 0.5-5% of cross-linking auxiliaries. The main materials of the composite ink adopt the no benzene, no ketone-polyurethane resin which is tested to find no halogen or heavy metal, so as to meet the environmental protection requirements, thereby not polluting the environment in the process of the terminal treatment. Since the no benzene, no ketone-polyurethane resin has good solubility, when the composite ink is diluted by 10%, the printing can reach the concentration of other existing ink, so that the transfer rate of the customer printing is increased by 10%, and the ink redissolving property can be fully improved.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a composite ink and a preparation method thereof. Background technique [0002] Composite ink technology is the combination of ordinary (oily) ink and UV curing technology, mixing common ink components with UV curing materials, mixing two or more anti-counterfeiting inks in a certain proportion, and then developing new performance inks. The composite ink is also called inner printing ink or mixed ink. Composite ink has the following characteristics: low odor; bright color, dull; soft conjunctiva; not resistant to abrasion; high peeling strength; good for compounding, etc. [0003] Existing composite inks use ester-soluble polyurethane resins and vinyl chloride as ink binders, and are dispersed and ground with organic pigments to meet later composite strength requirements. However, the vinyl acetate resin is difficult to dissolve, and the prepared composite ink has poor resolubili...
