Description
Technical Field
The invention relates to the technical field of tobacco filtration, in particular to a plasticizer of a cellulose acetate tow for cigarettes and a cellulose acetate filter rod for cigarettes.
Background
With the development of the tobacco industry, various cigarette products, such as traditional electronic cigarettes, low-nicotine cigarettes, and the like, are introduced to meet the demand of health ideas of consumers. Due to the continuous development of new products, the requirements on cigarette filters are also continuously increased, such as further reducing harmful substances and ensuring the satisfaction of the smoke quantity of the smoke. Therefore, attention is increasingly paid to filter sticks having low resistance and high adsorption. Therefore, the chinese patent CN 110326815 produces a low-resistance and high-filtration filter stick by using a polylactic acid degradable material through a melt spinning production line, but the method cannot provide good mechanical properties, that is, the filter stick is softened by high-temperature smoke, the filtration efficiency of the filter stick is greatly reduced, and expensive nano graphene and other materials are required.
The filter stick for cigarette in the market at present mainly uses acetate fiber tows, and the method is mature and low in cost. However, the molecular structure of the acetate fiber contains a large amount of carboxyl and hydroxyl, so that strong intermolecular entanglement is formed, and the processing difficulty is greatly increased. Therefore, it is necessary to improve the intermolecular entanglement by adding a plasticizer and to ensure good mechanical properties, diffusibility, and the like after molding of the composite system. As a filter stick for cigarettes, the filter stick also has no influence on the flavor of the cigarettes. The above-mentioned performance requirements therefore place extremely high demands on the plasticizer.
The traditional acetate tow plasticizer for cigarettes mainly depends on glycerol triacetate. The glycerol triacetate plasticizer is colorless viscous liquid, and can effectively improve the processability of the acetate fiber tows and the hardness and mechanical requirements after forming. However, the plasticizer is a slow-drying plasticizer and cannot meet the diversification requirement of the tobacco.

The plasticizer comprises the following components in percentage by weight: 16% of butyl citrate plasticizer, 13% of polyalcohol polyethylene glycol plasticizer, 17% of fat adipate plasticizer and 44% of glycerol triacetate.
The embodiment provides a high-efficiency low-resistance acetate fiber tow plasticizer for cigarettes, and the processing method is mixing by a ball mill. The preferred compound plasticizer using amount of the high-efficiency low-resistance cigarette acetate fiber tow plasticizer in the acetate fiber filter stick is 15%.
Comparative example 2
As a comparative example, only triacetin was used as a plasticizer of the acetate tow, and the plasticizer ratio was 20%.
The filter rods prepared in the above examples and comparative examples were subjected to comprehensive performance evaluation, and the results are shown in Table 1, and the test samples were filter rods having a length of 30mm and a circumference of 22 mm.
TABLE 1 comprehensive Property evaluation Table of examples
Compared with Chinese patent CN 110326815, the acetate tow filter rods prepared by the embodiment have low suction resistance and relatively high interception, and show efficient curing time and good processing performance. After curing, the examples show good mechanical properties. Has good toughness. Therefore, the high-efficiency low-resistance acetate fiber tow plasticizer for cigarettes can provide a plasticizing system with excellent comprehensive performance, and meets different application scenes.
