Preparation and application of crop waste cigarette filter additive carrier materials

Abstract

Disclosed is preparation and application of crop waste cigarette filter additive carrier materials. The carrier materials use crop waste such as crop straw, or corncob, or peanut shells or cane trash as raw materials, the processes of washing, offensive odor removing, drying, smashing and sieving are conducted in sequence, and finally the crop waste cigarette filter additive carrier materials are prepared. After the carrier materials are loaded with cigarette harm reduction agents or flavoring agents directly or chemical modification is conducted, the carrier materials are added into a cigarette filtering rod so that a binary or multielement composite filtering bar can be achieved, and the crop waste cigarette filter additive carrier materials are applied to cigarette filters and have the advantages of reducing harmful ingredients of cigarette smoke, adding fragrance, improving smoking quality and the like. The crop waste cigarette filter additive carrier materials further have the advantages that crop waste materials are provided with porous structures, and the crop waste cigarette filter additive carrier materials are rich in cellulose, hemicellulose, lignin and the like, wide in source, simple in production technology, low in cost, environmentally friendly, capable of facilitating recycling of the waste and the like, thereby being excellent cigarette filter additive carrier materials.

Description

[0001] technical field [0002] The invention belongs to the technical field of cigarettes, and relates to a cigarette filter, in particular to the preparation and application of a crop waste-type cigarette filter additive carrier material. Background technique [0003] Most of the existing cigarette filter additive carriers are chemically synthesized inorganic porous materials and polymer porous materials, such as activated carbon, silica gel, porous alumina, molecular sieves, mesoporous materials, ion exchange resins, and the like. The patent US 5909736 uses activated carbon as a carrier to prepare a cigarette filter additive by impregnating hemoglobin or attaching transferrin, hydrogen peroxide, protoporphyrin and cytochrome. Patent CN 1883320 uses activated carbon as a carrier, selects plants that have a relationship with tobacco, extracts the active ingredients from them, and applies them to activated carbon to make feed activated carbon. Patent CN 101669678 uses diato...
