Aqueous gravure ink for tipping paper and preparation method thereof

Abstract

The invention discloses aqueous gravure ink for tipping paper and a preparation method thereof. The aqueous gravure ink for tipping paper is prepared from pigments, filler, a modified casein solution, stearyl alcohol polyoxyethylene ether, 1,2-pentanediol, a wetting dispersant, a defoamer, a cosolvent and deionized water. The modified casein solution synthesized by the invention plays an anchoring role on the pigments, so that the dispersing stability and leveling property of the ink can be improved, and casein is loose to form a film, so that the ink film is good in ventilating property, and the effects of reducing tar and harmful components in the smoke is achieved; N-vinyl pyrrolidone is excellent in moisturizing property and is used together with stearyl alcohol polyoxyethylene ether and 1,2-pentanediol to effectively prevent printing paper from being crimped and deformed as the printing paper absorbs excessive water; by introducing trimethylolpropane triacrylate, a polymer can form a three-dimensional netty structure, so that the film-forming ventilating property is improved and the adhesive force is enhanced. The aqueous gravure ink for tipping paper prepared by the method is non-toxic and odorless, and good in dispersing stability, and a printed product which is dried does not deform and crimp, and is excellent in ventilating property.

Description

technical field [0001] The invention relates to the fields of fine chemical technology and printing raw materials, in particular to a water-based gravure ink for tipping paper and a preparation method thereof. Background technique [0002] Tipping paper is "tipping paper for cigarettes", which is a special paper for connecting cigarettes and filters. At present, most tipping paper printing factories use alcohol-soluble and ester-soluble inks to print tipping paper. The large amount of volatile organic solvents involved in the printing process and the solvent residues in the printed matter will have a certain impact on the environment and people's physical and mental health. . With the promulgation of mandatory standards such as "Limits of Volatile Organic Compounds in Cigarette Rod and Packing Paper" YC263-2008 in 2008, the use of products that do not comply with industrial policies is restricted and phased out. Tipping paper printing The use of environmentally friendly wa...

Problems solved by technology

[0003] At present, the main problem of water-based gravure ink for printing on tipping paper is: because the water-based ink uses a large amount of water as a solvent, and the tipping paper is thin, has large pores, and absorbs quickly, causing the tipping paper to absorb too much water. If there are too many, the paper will suffer from serious shrinkage deformation, decrease in tensile strength, and paper becomes brittle.

Since the perforated tipping paper only has high air permeability in the fixed perforated area, the air permeability of ordinary tipping paper without perforation is very low, usually only 2 CU~10 CU, so the dilution of smoke is not uniform , which has a great influence on the taste of cigarettes
