A method of making a honeycomb smoking filter rod, a filter rod and uses

Abstract

The application discloses a preparation method of a honeycomb filter rod for cigarettes, the filter rod and application, and comprises the following steps: mixing a composite adsorption carrier material with essence, and adsorbing the essence on the composite adsorption carrier material; wherein the composite adsorption carrier material comprises at least two of mesoporous silica, gamma-cyclodextrin, porous starch and sodium carboxymethyl cellulose; the adsorption amount of the essence accounts for 20%-50% of the mass of the composite adsorption carrier material; the composite adsorption carrier material with the adsorbed essence is extruded into a honeycomb filter rod blank through a honeycomb mold under the conditions of room temperature to 80 DEG C and a pressure of 0.5-5 MPa, so that a filter rod blank body with a honeycomb structure is formed; the filter rod blank body is dried under the condition of a microwave power of 500-3000 W for 1-10 minutes, so that a honeycomb filter rod base body is obtained; a chitosan coating is formed on the surface of the honeycomb filter rod base body, and the honeycomb filter rod for cigarettes is obtained; the method and the filter rod can realize slow-release, flavor enhancement, moisture retention, tar reduction and harm reduction simultaneously.
