Abstract

The invention discloses vegetable protein nano-fiber composite paper. A preparation method of the vegetable protein nano-fiber composite paper comprises: dissolving vegetable protein in a solvent to form a spinning solution, and performing electrostatic spinning on the spinning solution on the surface of a cigarette filter rod shaping paper to form a vegetable protein nano-fiber film so as to obtain the vegetable protein nano-fiber composite paper, wherein in the spinning solution, the mass fraction of the vegetable protein is 8-30%; during electrostatic spinning, the spinning voltage is 25-80 kV, the receiving distance is 10-30 cm, and the winding speed of the cigarette fiber rod shaping paper is 20-1000 mm / min. The invention also discloses an application of the vegetable protein nano-fiber composite paper in preparation of a cigarette filter rod for reducing the release amounts of benzopyrene and nitrosamine in mainstream smoke of cigarettes. Compared with a filter rod prepared from common cigarette filter rod shaping paper, the filter rod prepared from the vegetable protein nano-fiber composite paper disclosed by the invention can effectively reduce the release amounts of benzopyrene and nitrosamine in the mainstream smoke of cigarettes, wherein the release amount of benzopyrene is reduced by 28.7% at most, and the release amount of nitrosamine is reduced by 28.3% at most.

Description

technical field [0001] The invention relates to the field of tobacco filter materials, in particular to a vegetable protein nanofiber composite paper and a preparation method and application thereof. Background technique [0002] The tobacco industry occupies an important position in the national economic system, and its existence and development are of outstanding value in meeting people's normal needs and increasing national fiscal revenue. However, with the development of economy and society, consumers' dependence on tobacco products and the harmfulness of tobacco products to the health of smokers have also attracted more and more attention. Using practical methods to efficiently remove harmful gases such as hydrogen cyanide, nitrosamines, benzopyrene, crotonaldehyde, and ammonia produced during tobacco combustion, and to reduce their harm to consumers’ health to a certain extent, has become a major Issues of concern to tobacco companies and industry workers. [0003] E...
