Abstract

The invention provides a smoke filter material. The smoke filter material comprises a first cellulose diacetate film layer, a lipophilic polymer material film layer and a second cellulose diacetate film layer in sequence along the entry direction of the smoke. The invention also provides a preparation method and application of the smoke filter material. The provided smoke filter material improvesthe adsorption function for the tar oil and can simultaneously filter smoke particles and harmful gas; the moisture of the smoke of the smoke filter material is increased to improve the wetness degree; when the smoke filter material is applied to a cigarette filter, the discomfort of dryness caused by the smoke is lowered, the taste is improved, and the smoke filter material has a wide applicationprospect and higher application value.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a smoke filter material, a preparation method and application thereof. Background technique [0002] The smoke produced by burning cigarettes contains a large number of direct carcinogenic chemicals, among which tar has the highest content. Tar is the product of incomplete combustion of organic matter under anoxic conditions. Its main components are complex mixtures of many hydrocarbons and hydrocarbon oxides, sulfides and nitrogen compounds, including cadmium, arsenic, amines, nitrosamines and radioactive isotopes. And other carcinogens and phenols, fumaric acid and other cancer-promoting substances. [0003] Cigarette products currently on the market usually use cellulose diacetate as the filter rod material to prevent smokers from directly inhaling a large amount of smoke, but there is still room for optimization of the absorption of tar in cigarette smoke.
