Abstract

The invention discloses a degradable type composite filter rod for cigarette and a preparation method thereof. The preparation method comprises the following steps: edible raw materials such as grain, tubers, pulses or starchy are cut and smashed into uniform particles; 65-90% of cut and smashed raw materials are fully mixed with 3-30% of cyclodextrin and 5-15% of gelatin; 80-90 DEG C water with a weight of 10-30% of the total weight of the mixture are added, and a puffed material is obtained after stirring and mixing for 20-30 min; the puffed material are extruded and formed to obtain a puffed filter of a cigarette; a composite filter rod for cigarette is obtained by using the puffed filter and convention cellulose acetate fibers. According to the invention, the degradable type composite filter rod allows a cigarette filter to be novel and variable in structure without changing the physical property and the smoking quality of a cigarette, and is safe, nontoxic and environment-friendly; the degradation time of the degradable type composite filter rod is shortened; the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a method for preparing cigarette auxiliary materials, in particular to a method for preparing a degradable composite filter stick for cigarettes. Background technique [0002] At present, the used filter rod material of cigarettes is mainly cellulose acetate filter rod. In the presence of sunlight and water at the same time, cellulose acetate (referred to as "acetate") will be deactivated and produce water-soluble acetate, which can be biodegraded. However, this degradation process is slow and takes a long time. In addition, during the forming process of the cigarette filter rod, the mutual adhesion of the plasticizer and the wrapping of the tipping paper during the rolling process will cause the degradation of the acetate fiber in the cigarette filter. more difficult. [0003] With the continuous increase in the production and sales of filter cigarettes, the environmental pollution of non-degradable ordinary filter sticks ha...
