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 a graphene-based cigarette paper and a preparation method thereof, belonging to the technical field of cigarette materials. The method comprises the steps of soaking the graphene oxide in a solvent and then ultrasonicating, adding tobacco flavor, humectant and functional auxiliary agent to the obtained graphene oxide dispersion liquid, and mixing evenly to obtain the graphene functional compound. Apply the graphene functional compound on the surface of the cigarette paper, and then dry it to obtain the graphene-based cigarette paper; or, add the obtained graphene functional compound in the papermaking modulation process, and then obtain the graphene-based cigarette according to the conventional preparation process Paper. The present invention can solve the problem of easy volatilization and loss of fragrance and flavor carried on cigarette paper, and can modify the shape of cigarette smoke based on the properties and characteristics of graphene, and improve the sensory quality of cigarettes. In addition, the graphene functional compound can also be sprayed / spin-coated on the cigarette paper to give personalized patterns, which can give cigarettes a dual perception experience of vision and smell while enriching the adjustment of cigarette aroma / smoke.

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...
