Problems solved by technology

[0004] Aiming at the disadvantages in the prior art that activated carbon materials are directly applied to reduce aldehyde compounds in cigarette smoke, the adsorption capacity is too large, the selectivity is poor, and the taste of cigarettes is greatly affected. Cigarette filter additives that are aldehydes in mainstream cigarette smoke and do not affect the taste of cigarettes

Abstract

The invention discloses a cigarette filter tip additive removing aldehydes in the cigarette mainstream smoke and a preparation method and application thereof. The cigarette filter tip additive is a compound material composed of tobacco material particles, carbon material and adhesive material in an adhered manner. The cigarette filter tip additive added into a cigarette filter tip is capable of reducing the aldehydes in the cigarette mainstream smoke effectively and selectively, and the cigarette taste is not influenced; the preparation method of the cigarette filter tip additive is easy and fast to implement, the cost is low, and the industrial production can be met.

Description

technical field [0001] The invention relates to a cigarette filter additive capable of removing aldehydes in mainstream smoke of cigarettes, a preparation method and application thereof, and belongs to the technical field of cigarette filter preparation. Background technique [0002] Cigarette smoke is a very complex chemical system produced during the smoking process of cigarettes. There are more than 4,000 chemical components that have been identified so far, some of which are harmful to the human body and the environment, mainly including carbon monoxide. , hydrocyanic acid, volatile aldehydes, ammonia, nitrosamines, benzopyrene and phenols, etc. More than 20 kinds of aldehydes have been found in the gas phase components of cigarette smoke, among which the highest content is formaldehyde, acetaldehyde, propionaldehyde, acrolein, crotonaldehyde and furfural. These volatile aldehydes are especially formaldehyde, Acrolein and crotonaldehyde are toxins of airway cilia and ca...
