Abstract

The invention relates to a preparation method of a cellulose acetate open pore porous foam material filter tip spice rod. According to the method, cellulose acetate, polypropylene and auxiliary agents are proportionally mixed; then, a certain amount of supercritical carbon dioxide is added; the supercritical carbon dioxide is used for assisting the extrusion into a mold for forming; then, foaming is performed to obtain a cellulose acetate open pore porous foam material; then, a flavoring agent is attached onto the cellulose acetate open pore porous foam material through spray coating or immersion; the cellulose acetate open pore porous foam material filter tip spice rod is obtained. The cellulose acetate open pore porous foam material filter tip spice rod obtained by the preparation method provided by the invention can well adsorb the spice additives; during the suction, the fragrance elution and release can be favorably realized. The porous structure per se of the spice rod has a certain interception effect on the smoke gas; the fragrance and the taste of a cigarette can be improved; the quality of a cigarette product is improved. The method provided by the invention has the advantages that the technical process is simple; the implementation is easy; the equipment is simple; the method can be directly used for cigarette processing; the popularization and the application are convenient.

Description

technical field [0001] The invention relates to a method for preparing a cellulose acetate perforated and microporous foaming material filter tip fragrance stick, which belongs to the technical field of cigarettes. Background technique [0002] In recent years, with the improvement of people's living standards, smokers have higher and higher requirements for the taste of cigarettes. How to design cigarettes with different flavors to meet the taste requirements of different groups of people has become a research topic for cigarette workers. focus direction. [0003] At present, cigarette flavoring and harm reducing additives are widely used, and play an important role in cigarette harm reduction, tar reduction and flavor compensation. The existing additive technology mainly adds additives to shredded tobacco and filter sticks, but when added to shredded tobacco, the additives will participate in the combustion at the same time as the cigarette is sucked, which will not only ...
