Abstract
The utility model discloses a functional film composite particle. The functional film composite particle consists of a particle material and a functional film which wraps the particle material, wherein the particle material is made of natural plants which are rich in cellulose and starch composition such as kudzu vine roots or burdock; the functional film is formed by mixing polyvinyl alcohol with chitosan. A preparation method of the functional film composite particle comprises the step of wrapping the particle material with the functional film through a fluidizing and spraying method by the aid of hydrogen bonds formed between molecular chains. The functional film composite particle can be used for manufacturing a filter stick. According to the prepared composite particle filter stick, the environmental protection effect, the aroma enhancement effect and the moisture keeping effect of the natural plants can be brought into full play, and harmful organic substances in cigarette smoke can also be effectively adsorbed.
Description
Technical field
The utility model relates to a kind of granular adsorption material that is coated with film material and as the application of cigarette filter material.
Background technology
By powder stock granulation material, by a film of the peripheral parcel of particulate material, particulate material is used alone as to sorbing material, particulate material is embedded in fibrous material as accordance filtering adsorbing material, to reach the objects such as absorption, filtration, slowly-releasing or shielding, these technology are technological means that the fields such as tobacco industry, chemical industry, mechanotronics or agricultural often adopt.
