Problems solved by technology

[0008] Through the analysis of the trial production in the tobacco factory, it can be seen that it is difficult to prepare the filter rod structure with the polylactic acid sheet film and connect it with the traditional filter rod, and special equipment needs to be designed for processing and production. The production process is not easy to be continuous and the production efficiency is low; The film absorbs heat, softens and collapses and easily blocks the flue gas channel
The process of adding phase change materials is complicated, the cost is high, and it is not easy to promote industrialization
The polylactic acid groove structure has a certain cooling effect, but the current process is to use single-component tow, and the shape depends on the traditional gluing process
However, there is no suitable binder for polylactic acid materials in the existing product application technology, and water-based glue for polypropylene tow is mainly used. On the one hand, the process is complicated (drying water is required), and on the other hand, water-based glue has certain hazards.
The groove structure filter rods of cellulose diacetate tow and polypropylene tow have no obvious cooling effect in experiments, and triacetin plasticizer needs to be added to form cellulose diacetate tow, which is harmful to a certain extent

Abstract

The invention relates to a safe and environment-friendly cooling filter tip rod and a preparation method thereof. The preparation method comprises the process of extracting, opening and scutching, steam heating and bonding, air cooling and forming, and cutting and collecting. The hollow cooling filter stick is heated and bonded by steam in the forming process, and a plasticizer is not added, so that the hollow cooling filter stick is a safe and environment-friendly new cooling filter material for low-temperature cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a safe and environment-friendly cooling filter tip and a preparation method thereof. Background technique [0002] In recent years, the world has been paying attention to issues such as smoking, health and second-hand smoke, and the disadvantages of traditional tobacco products have become increasingly prominent. The structure of tobacco products is being adjusted towards diversification and smoke-free development. In view of this, the research and development of new tobacco products that can meet the needs of current consumers and reduce the harm of smoking and second-hand smoke has become an important task for the future development of the tobacco industry. [0003] Traditional tobacco products refer to smoke-burning tobacco products. Chemical reactions occur through tobacco combustion, releasing various chemical substances for smokers to smoke. Compared with t...
