Method for preparing tipping paper for water-based ink

Abstract

The invention relates to a method for preparing tipping paper for water-based ink, which comprises the following steps: (1) dissolving water-based ink with a mixture, in which the proportion of 95% ethanol to water is 1:1, and measuring with a No.2 submerged viscosity cup to lead the viscosity to be 15-19 seconds; (2) before printing, feeding tipping base paper, of which the endwise tensile strength is greater than 2.0 KN / m and the ration is 34-40 g / m<2>, into the drying zone of a printing press, so as to preheat the tipping base paper at 110-120 DEG C; (3) after the printing is started, printing the preheated tipping base paper in the printing zone of the printing press by using an intaglio plate and rubber rollers, wherein the engraving resolution of the intaglio plate is 60-120 lines / centimeter, the Shore hardness of the rubber rollers is 45-80 HS, and the pressure of the rubber rollers is 3-6 Kg; and heating the tipping base paper in the drying zone of the printing press at 150-180 DEG C, repeating the step for 2-4 times, and finally, feeding the printed tipping paper into the drying zone once again, and heating the printed tipping paper in the drying zone at 110-120 DEG C.

Description

technical field [0001] The invention relates to a method for preparing tipping paper, in particular to a method for preparing tipping paper for water-based ink. Background technique [0002] Tipping paper, also known as tipping paper, belongs to auxiliary materials for cigarettes. It is a special paper product used to connect cigarette filters and cigarette sticks, that is, the outermost layer of paper on cigarette filters. It is usually printed with white tipping base paper. of.

Problems solved by technology

The existing tipping paper is printed with alcohol ink or ester-soluble ink, and a certain amount of volatile organic compounds will remain on the surface of the tipping paper. This paper is used to connect the filter tip and the cigarette, and is sealed in the package after being packaged. In the cigarette case, the residual volatile organic compounds in the tipping paper will inevitably diffuse into the shredded tobacco. During the smoking process of the cigarette, there will be a feeling of odor, which affects the taste of the smoke and increases the harmfulness of the smoke. In addition, in the process of printing tipping paper with alcohols and ester solvent inks, a large amount of organic waste gas containing these solvents will be discharged, which not only causes a burden to the environment, but also causes a waste of organic solvent resources; in addition, Compared with water-based inks, using alcohol and ester solvent inks to print tipping paper will increase production costs and affect the economic benefits of enterprises
