Problems solved by technology

[0004] However, these methods for reducing the temperature of the flue gas are all aimed at traditional cigarettes, and cannot solve the high temperature resistance requirements faced by filters in new cigarettes
The heating temperature of the tobacco material in the new cigarette is lower than the temperature of 900 ℃ and above in the combustion process of the traditional cigarette, and the efficiency of smoke generation is low

Abstract

The invention relates to the technical field of tobacco manufacture, in particular to a high temperature-resistant filter tip of a cigarette, a preparation method and application thereof. The high temperature-resistant filter tip of the cigarette is formed by composition between a high temperature-resistant function section and a tow section. The high temperature-resistant function section is formed by processing a high temperature-resistant material. Therefore, problems of a conventional filter tip of a cigarette are effectively resolved. The conventional filter tip of the cigarette is not likely to deform, sink and fuse by preventing the structure from damage at high temperature. One or multiple airflow channels is/are arranged in the high temperature-resistant function section. According to the length proportions of the high temperature-resistant function section and the tow section as well as pressure drop of the tow section and other factors, sizes, numbers and position distribution of the one or multiple airflow channels in the high temperature-resistant function section are regulated. Due to a hollow structure of the high temperature-resistant function section, obstruction,interception and other effects of the filter tip are reduced. The loss of smoke in the filter tip is lowered. Therefore, fluidity of smoke is enhanced.

Description

technical field [0001] The invention relates to the technical field of tobacco production, in particular to a high-temperature-resistant smoke filter tip and its preparation method and application. Background technique [0002] Acetate fiber is currently the most widely used cigarette filter material. It improves the smoking quality of cigarettes by trapping harmful components such as tar in cigarette smoke. However, acetate fiber is easily softened by heat during the smoking process of cigarettes, and thermal collapse occurs. When a traditional cigarette burns, the temperature distribution gradually decreases below 100°C from the burning cone to the filter. However, the new type of cigarettes does not have a combustion process. Generally, heating sheets, heating rods, heating chambers, etc. are used to heat the cigarettes to generate smoke. However, cellulose acetate is prone to softening and melting at this temperature, and may decompose above 300°C. Therefore, the tradi...
