Embodiment Construction

[0015] A method for preparing a water-based coating for cigarette forming paper, comprising the following steps:

[0016] (1) Add carboxymethyl cellulose to water and stir to dissolve completely to obtain carboxymethyl cellulose solution, then slowly add ferrous sulfate solution to the carboxymethyl cellulose solution, and stir under nitrogen protection React for 0.5h to obtain carboxymethyl cellulose complex iron solution, the volume ratio of carboxymethyl cellulose solution to ferrous sulfate solution is 2:0.5;

[0017] (2) Dissolve chitosan in acetic acid solution at a solid-to-liquid weight ratio of 1:40 to obtain a chitosan solution, and then combine the chitosan solution with the carboxymethyl cellulose complex iron solution obtained in step (1) Mix evenly according to the volume ratio of 1:0.15, then slowly dropwise add sodium hydroxide solution with a mass fraction of 5% and stir for 0.5h, wash the solid product to obtain composite gel microspheres;

[0018] (3) Add 5...

Abstract

The invention discloses a method for preparing a water-based coating for cigarette forming paper. Firstly, carboxymethyl cellulose solution and ferrous sulfate solution are blended to obtain carboxymethyl cellulose complex iron, and then mixed with chitosan solution evenly, dripping Add sodium hydroxide solution for gelation reaction to form gel microspheres, and at the same time, due to the change of pH and the oxidation of oxygen in the air, iron ferric oxide nanoparticles are uniformly generated in situ in the gel microspheres, thereby obtaining a composite gel The microsphere is uniformly mixed with a polyvinyl alcohol solution and a filler to obtain a water-based coating for cigarette forming paper. The water-based paint for cigarette forming paper prepared by the invention not only has good adhesion to the forming paper, but also has the auxiliary functions of reducing burnt damage and improving the smoking quality of cigarettes, and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of cigarette materials, in particular to a method for preparing a water-based paint for cigarette forming paper. Background technique [0002] Cigarette forming paper is a commonly used auxiliary material for cigarette production, and its main function is to bind the tow. Due to its air permeability, it can dilute harmful components such as tar in the smoke, but its contribution to the quality of cigarette smoke has relatively large limitations. CN101914872A discloses a water-based coating for chitosan-containing cigarette forming paper. By coating the chitosan-containing coating on the forming paper, chitosan is used to absorb tar, nicotine, moisturize and increase flavor, and improve the taste. The effect is to improve the quality of flue gas. However, chitosan alone has limited moisturizing and harm reduction effects, and the improvement effect on cigarette wrapping paper when used as a coating is insuf...
