Problems solved by technology

Because this solvent-based varnish contains organic solvents, it will introduce certain harmful components into cigarettes and cause pollution to the environment.
As people pay more and more attention to environmental protection and "smoking and health" issues, the development of high-performance water-based varnishes to replace solvent-based varnishes has become a research hotspot in the field of cigarette packaging, but there is no good solution in the prior art.

Abstract

The invention discloses a water varnish for inner liner paper of cigarette and the preparing way for the varnish. The water varnish is obtained by synthesizing through taking acrylic acid, vinylacetate, butyl acrylate, ethyl acrylate, methyl methacrylate and styrene as reaction monoblock, n-butyl alcohol, isopropyl alcohol and ethyl alcohol as solution, benzoyl peroxide as initiator, and ammonia or ethanolamine as neutralizer. Further, the water varnish got is mixed evenly with essence for cigarettes, and water varnish with fragrance is obtained. The product takes water as solution, has no organic solution volatimatter during the production and use, no pollution on the environment and no harm on one's body. The invention has a low cost, easy process, needs no changing existing process and equipment, and can adjust the fragrance formula depending upon user's demand, so that the product can coordinate with fragrances of cigarettes of different makes, the safety of cigarettes can be improved, quality of cigarettes can be increased comprehensively. The invention is of a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of cigarette packaging materials, and in particular relates to a water-based varnish used for inner lining paper of cigarettes. At the same time, the invention also relates to a preparation method of the water-based varnish. Background technique [0002] Cigarette packaging is an important part of cigarette production and the last process in the entire production process. In the whole process of cigarette production, circulation and consumption, the quality of packaging materials plays an important role in maintaining the quality of cigarette products, promoting sales and guiding consumption. Compared with other commodities, the requirements for cigarette packaging materials have certain particularities, such as: no peculiar smell, non-toxic and harmless to the human body, and certain moisture-proof and air-permeable properties. [0003] Aluminum foil paper for cigarettes (also known as inner lining paper)...
