Problems solved by technology

However, this kind of cigarette paper is common at present. Flavor substances are easy to be lost in the process of cigarette paper production and storage, and the retention time of fragrance substances is short, or they can only be endowed with aroma-generating functions, and cannot give personalized visual effects at the same time. features
In addition, the papermaking process of cigarette paper restricts it to high-temperature drying at the end, which may easily lead to the loss of volatile components and affect the quality of cigarette products

Abstract

The invention relates to graphene-based cigarette paper and a preparation method thereof and belongs to the technical field of cigarette materials. The preparation method includes: soaking graphene oxide into a solvent, performing ultrasonic treatment to obtain graphene oxide dispersion liquid, adding cigarette perfume, a humectant and functional auxiliaries into the graphene oxide dispersion liquid, and evenly mixing to obtain a graphene functional compound; applying the graphene functional compound to the surface layer of cigarette paper, and drying to obtain graphene-based cigarette paper;or adding the obtained graphene functional compound in a papermaking preparation procedure, and then using a conventional preparation process to prepare the graphene-based cigarette paper. The graphene-based cigarette paper and the preparation method thereof have the advantages that the difficulty that fragrance carried by the cigarette paper is prone to volatilization loss, cigarette smoke form can be modified by the aid of the characteristics of graphene, and cigarette sensory quality can be improved; in addition, the graphene functional compound can be applied to the cigarette paper throughspraying / spin coating so as to endow the cigarette paper with personalized patterns, and cigarette fragrance / smoke is enriched and regulated while cigarettes are endowed with double perception and experience of vision and smell.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a graphene-based cigarette paper and a preparation method thereof. Background technique [0002] Cigarette paper, also called coil paper, is used to wrap cigarette tobacco. Compared with other cigarette accessories, the biggest feature is that it participates in the burning of cigarettes. During the smoking process of cigarettes, not only physical changes but also chemical changes occur. Therefore, it can be regarded as an important part of the cigarette leaf group, so the cigarette paper plays a key role in the influence of the smoking taste of the cigarette. Nowadays, for young consumers, the development of cigarette paper focuses on meeting multiple functions. For example, it needs to provide exquisite appearance support for the brand image while satisfying the taste requirements. Developed countries such as the United States and Europe even require that cigaret...
