Problems solved by technology

At the same time, due to the lack of binding force between the external filler and the tobacco plant fiber, the tensile strength of the reconstituted tobacco leaf often decreases. In addition, the function of the traditional filler is relatively single, and the research on fillers with multiple functions has not yet made significant progress.

Abstract

The invention discloses a preparation method of a geraniol-graphene oxide slow-release heat-conducting cigarette composite material. In this application, the hydroxyl group in the geraniol molecule and the hydroxyl group on the surface of the graphene oxide form a chemical bond such as a hydrogen bond to form a stable composite material. When the composite material is added to the tobacco sheet, the hydroxyl groups on the surface of the composite material can form chemical bonds such as hydrogen bonds with the tobacco plant fibers, thereby reducing the influence of the addition of the material on the decline in the strength of the tobacco sheet. After adding the composite filler, the tobacco flakes can be endowed with rich rose aroma and certain respiratory tract health care effect. In addition, during the smoking and heating process, graphene oxide can slow the release of aroma, which is conducive to the uniform and slow release of aroma; and the good thermal conductivity of graphene is conducive to the conduction of heat after the tobacco sheet is heated.

Description

technical field [0001] The invention relates to the technical field of reconstituted tobacco leaves, in particular to a method for preparing a geraniol-graphene oxide slow-release heat-conducting composite material for cigarettes. Background technique [0002] Paper-making reconstituted tobacco leaves are mainly made of waste tobacco powder, tobacco stems and tobacco shreds in the process of cigarette production, plus auxiliary materials such as plant fibers, tobacco extracts, forming aids and fillers, which are close to natural tobacco leaves through papermaking technology. sheet, and compounded in cigarette production. With the continuous development of technology, the research and development and production of paper-making reconstituted tobacco have made great progress, but there is a certain gap between the product quality of domestic paper-making reconstituted tobacco and the products of foreign advanced enterprises. In order to improve the overall quality of paper-mak...
