Document Type and Number:
WIPO Patent Application WO/2022/121480
Kind Code:
A1
Abstract:
Disclosed are a fully degradable cooling assembly, a preparation method therefor and use thereof. The fully degradable cooling assembly comprises a fully degradable cooling master batch for reducing smoke temperature. The cooling master batch is made of a plurality of fully degradable materials and a solubilizer. The preparation method for the fully degradable cooling assembly comprises the following steps: obtaining the plurality of fully degradable materials and mixing same, and adding the solubilizer during the mixing to obtain a raw material for granulation; and extruding and granulating the raw material by using an extrusion and granulation process, so as to obtain the fully degradable cooling master batch. Use of the degradable cooling assembly in a cooling filter bar for heat-not-burn cigarettes. The use comprises the use of the cooling master batch in the cooling filter bar; and/or the use of cooling pipes in the cooling filter bar. The present invention can effectively reduce the temperature of the smoke at the inlet end of cigarettes, and does not affect the suction resistance and the filtering efficiency of the cooling filter bar.
