Problems solved by technology

[0004] The purpose of the present invention is to overcome the surface sizing in the prior art when producing cigarette tipping paper which will reduce the porosity of the paper and reduce its air permeability, thereby making the cigarette tipping paper less effective in reducing tar and harm, which is not conducive to To solve the problem of human health, a preparation method of base paper for flexographic printing cigarette tipping is provided. During the beating process, betaine is added to modify the pulp fiber, and polyepichlorohydrin-dimethylamine is added to the pulp to modify Filler can meet the requirements of use without surface sizing, which can effectively improve the air permeability of the base paper; at the same time, it can also endow the base paper with antibacterial properties, which is beneficial to human health

Abstract

The invention relates to the technical field of papermaking, and discloses a method for preparing cigarette tipping base paper for flexographic printing. (2) Pulp modification: add betaine with 10-20% of the mass of the pulp to the pulp, stir and react for 30-60 minutes, and then add polyepoxide with 50-60% of the mass of the pulp Chloropropane-dimethylamine modified filler, 1~1.5% PAE wet strength agent, 1~2% pulp inner glue and 1~2% AKD; (3) papermaking; (4) pressing, drying and calendering . In the invention, betaine is added during the beating process to modify the pulp fibers, and polyepichlorohydrin-dimethylamine modified filler is added to the pulp, so that the use requirements can be met without surface sizing, and the air permeability of the base paper can be effectively improved. ; At the same time, it can also endow the base paper with antibacterial properties, which is beneficial to human health.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing cigarette tipping base paper for flexographic printing. Background technique [0002] Cigarette tipping paper is an important material for the production of cigarettes. It is a special paper that connects the filter tip and the cigarette branch through the processes of pre-press design, printing processing and post-press processing, based on the tipping base paper. . The tipping paper is in direct contact with the smoker's lips, and the harmful ingredients will enter the human body through the oral cavity. Therefore, the printing ink and coating of the tipping paper must be non-toxic and meet food hygiene standards. Traditional cigarette tipping paper printing methods mainly use alcohol-soluble or ester-soluble inks for gravure printing or offset printing, and organic solvents will cause harm to the human body. In order to meet the country's requireme...
