Problems solved by technology

The traditional tipping paper coating is oily, and most of them adopt the double-coating transfer process, plus compound glue, there are 3 layers on the paper, the process is complicated and the cost is high
In addition, although there are strict requirements on the amount of solvent residues, there will be residual solvents, which will not only damage health, but also affect the smell of cigarettes, etc.
In addition, the solvents of oil-based paints are all oil-based. During the printing and coating process, a large amount of organic solvents are consumed, and 90% of domestic enterprises cannot recycle them, resulting in waste of raw materials and increased costs.
At the same time, there are fire hazards in the production, use, storage and transportation of oil-based paints.
[0003] Regarding water-based paints, the hygienic indicators and safety are obviously better than those of oil-based paints, but most of them currently use a double-coating process, which has complicated procedures and high costs

Abstract

The invention discloses a water-seepage-proof high-light coating composition for tipping paper and a preparation method thereof; the coating composition comprises the following components by weight: 6-80 parts of main part resin, 20-30 parts of alkali soluble resin, 0-4 parts of bentonite, 0.1-0.2 part of a thickening agent and 0.1-0.2 part of a defoaming agent. During preparation, the main part resin is added into a reaction kettle for low-speed stirring; while stirring, the alkali soluble resin is added for low-speed stirring for 10min; while stirring, the bentonite is added for low-speed stirring for 5-10min; while stirring, the defoaming agent is added for high-speed stirring for 40min; while stirring, the thickening agent is added for low-speed stirring for 20min; and then a material is discharged for packaging. The preparation method has the advantages of simple process and low cost; the prepared coating composition is good in printing adaptability and good in water-seepage-proof effect, and radically solves the difficult problems that a general imitation glass card coating may permeate to the back of paper to cause a low coating gloss and cause the permeated coating to stick to a guide roller so as to influence production.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to an anti-seepage water-based high-gloss coating composition for tipping paper and a preparation method thereof. Background technique [0002] In recent years, the environmental protection requirements of the country and cigarette factories for tipping paper used for packaging cigarette filters have become more and more stringent. Since the tipping paper is in direct contact with the smoker's mouth, the coating of the tipping paper must meet the food hygiene requirements. The traditional tipping paper coating is oily, and most of them use a double-coating transfer process, plus composite glue, and there are 3 layers on the paper, the process is complicated and the cost is high. In addition, although there are strict requirements on the amount of solvent residues, there will still be residual solvents, which will not only damage health, but also affect the smell of cigarettes. ...
