Cigarette tipping paper water-based ink and preparation method

Abstract

The invention discloses cigarette tipping paper water-based ink and a preparation method, belonging to the technical field of water-based ink. The water-based ink is characterized by consisting of the following raw materials in parts by weight: 50-60 parts of water-based emulsion resin oil, 10-20 parts of iron oxide pigment, 10-20 parts of de-ionized water and 0.5-1.0 part of one or more of auxiliary agents of defoaming agent, anti-sedimentation agent, leveling agent, wetting agent, antibacterial agent, wetting dispersant and surface tension agent. The cigarette tipping paper water-based ink has the advantages of small fineness, high drying speed, high consistency, low viscosity, good dispersion stability, no setting precipitate, no agglomeration, no toxicity, no residual peculiar smell, good wet leveling property, good color development, no brittle fracture at a low temperature, no edge folding during drying, good water resistance, full and clear print, stable color, smooth and glossy surface, good storage stability and wide application range to printing raw paper and printing speed; and the cigarette tipping paper water-based ink can be produced by the method.

Description

technical field [0001] The invention belongs to the technical field of water-based ink, and in particular relates to a water-based ink for tobacco pine paper. Background technique [0002] Tipping paper, commonly known as tipping paper, is an important material for the production of cigarettes and a special paper for connecting cigarette filters and cigarettes. In order to meet the requirements of cigarette labeling and rich colors, the tipping paper usually needs to be printed, post-printed and other processes to become the final tipping paper product. The printing of tipping paper is usually gravure and flexo printing, and gravure printing is the main method, and its ink is currently mainly solvent-based gravure ink. In recent years, as people's awareness of safety, environmental protection and health has been continuously strengthened, a large number of printing inks used, a large number of volatile organic solvents involved in the printing process, and solvent residues...

Problems solved by technology

[0004] (1) Paper deformation is too large

Due to the use of a large amount of water in water-based ink, this causes the paper to absorb too much water, resulting in serious deformation of the paper

In addition, because the paper absorbs a large amount of water for many times, the tensile strength of the paper is reduced, and the paper becomes brittle, which will affect the quality of future cigarettes.

[0005] (2) The drying speed is too slow

[0008] The above factors have hindered the application of water-based inks on tipping paper
