Cigarette tipping phase-change material for cigarette tipping paper as well as preparation method and application of phase-change material

Abstract

The invention discloses a cigarette tipping phase-change material for cigarette tipping paper as well as a preparation method and application of the phase-change material. The cigarette tipping phase-change material for cigarette tipping paper comprises a component A and a component B. The component A comprises the following raw materials in parts by weight: 15-30 parts of alcohol-soluble acrylicresin and 70-85 parts of absolute ethyl alcohol. The component B is an ethylene-methyl methacrylate copolymer. A mass ratio of the component A to the component B is (7-9): (1-3). The phase-change material is firstly printed and then subjected to heat sealing, so the problem that an existing water-based filter tip adhesive is slow in drying can be solved, the production requirements of intaglio printing and a high-speed cigarette making machine are met, production efficiency is high, and the phase-change material can be applied to the fields of food, automobiles, electronics, textiles and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a cigarette phase-change material for cigarette tipping paper and its preparation method and application. Background technique [0002] Cigarette adhesives can be classified according to their uses into filter forming, rolling, and packaging, among which mouthpieces are used in the largest amount. The raw and auxiliary materials used in cigarette adhesives must be listed in the list of permitted substances for smoking materials and industry standards and enterprise standards for tipping paper, such as no organic solvent, non-toxic, no peculiar smell and no pollution, with suitable viscosity and good stability It is easy to apply mechanically and the surface is sticky and smooth after coating. With the continuous introduction of high-speed coiling units, the cigarette adhesive must meet the requirements of high-speed cigarettes, such as having a certain init...

AI Technical Summary

Problems solved by technology

[0003] Cigarette glue is divided into water-based type and hot-melt type. Its development has gone through stages such as starch glue, dextrin glue, carboxymethyl cellulose, and white glue. At present, water-based cigarette glue is mainly used, that is, vinyl acetate homopolymer Emulsions and vinyl acetate-ethylene copolymer emulsions, these two types of emulsions have a high film-forming temperature, hard and brittle films, poor bonding ability to complex packaging materials, and high prices

At the same time, because these two types of interface adhesives are water-based products, the drying speed of temporary coating is slow during production and use, and cannot meet the production requirements of high-speed cigarette making machines

In order to solve this problem, people have carried out appropriate deployment and modification on this basis, but the cost of modification has also increased, and it cannot be widely used
