Abstract

The invention discloses a grapheme type fiber cigarette filter and a preparation method thereof. The filter comprises a fiber carrier, wherein the fiber carrier is provided with a grapheme type material for absorbing harmful components in smoke. The filter loads the grapheme type material on a carbon fiber or acetate fiber carrier; and the carrier is added in the filter by adopting the binary filter production mode in the existing industries to produce a compound filter for absorbing harmful substances in the smoke which is generated when cigarettes are smoked. The filter applies unique phi absorption characteristics and higher surface active atom ratio of novel two-dimensional nanometer materials to efficiently absorb benzo [a] pyrene, volatile aldehyde ketone type cancer promoting molecules, phenol and HCN (Hydrogen Cyanide) under the condition of smaller adding quantity, so that the filter is environment-friendly and has no additional poison; as the amount is small and the effect is high, the harm of the cigarettes to human bodies is reduced under the condition of not influencing the inherent sensory quality of the cigarettes. And at the same time, the method has the advantages of simple technique, large-scale production and low cost, and has wide application foreground in the cigarette field of harm reduction and tar reduction.

Description

Technical field [0001] The invention relates to the technical field of cigarettes, in particular to a graphene fiber cigarette filter tip and a preparation method thereof. Background technique [0002] NH is produced during cigarette burning 3 Hazardous substances such as, CO, phenol, benzo[a]pyrene, HCN, crotonaldehyde, methylnitrosamine pyridinyl butanone (NNK), etc., enter the human body with smoke and cause harm when inhaled. Cigarette filters can prevent these substances from entering the human body to a certain extent. [0003] Initially, cigarette filters were dominated by single fiber materials, which had low adsorption efficiency for harmful substances. Later, with the development of material technology, bulk composite fibers, ion exchange fibers, metal or metal oxide-doped fiber materials, Nano carbon sols are used to make cigarette filters in different ways. For example, CN101019692A discloses a filter tip that is uniformly blended with activated carbon fiber accountin...
