Embodiment 1

[0016] Embodiment 1: The paper quality filter material of the cigarette that has active adsorption layer selects the paper that fiber constitutes as base material, grinds the selected molecular sieve material to 150 meshes, then evenly forms slurry with water or alcohol, binder, The mixing mass ratio of water or alcohol, adhesive, and adsorption material is 1:1:0.3, and the coating amount is 6 g / m by spraying or roller gluing 2 , with the base paper of the paper filter material as the carrier, the adsorption material with food adhesive is evenly applied to the surface of the paper filter material, dried and evaporated the excess water, the water content of the paper filter material base material is 8 wt %, cut and pack the paper filter material according to a certain width and length.

Embodiment 2

[0017] Embodiment 2: The cigarette paper filter material with active adsorption layer is to select the paper that fiber constitutes as the base material, and the selected active carbon material is ground to 170 mesh, and then it is evenly formed into a slurry with water or alcohol and a binder, and the water Or the mixing mass ratio of alcohol, adhesive, and adsorption material is 1:1:0.5, and the application method is spraying or roller gluing, and the coating amount is 8 g / m 2 , with the base paper of the paper filter material as the carrier, the adsorption material with food adhesive is evenly applied to the surface of the paper filter material, dried and evaporated the excess water, the water content of the paper filter material base material is 10 wt %, cut and pack the paper filter material according to a certain width and length.

Embodiment 3

[0018] Example 3: The cigarette paper filter material with an active adsorption layer is made of paper made of fiber as the base material, and the selected ion exchange resin material is ground to 200 meshes, and then mixed with water or alcohol and a binder to form a slurry evenly , the mixing mass ratio of water or alcohol, binder, and adsorption material is 1:1:0.9, and the application method is spraying or roller gluing, and the coating amount is 10g / m 2 , with the base paper of the paper filter material as the carrier, evenly apply the adsorption material with food adhesive to the surface of the paper filter material, dry and evaporate the excess water, the water content of the paper filter material base material is 15 wt %, cut and pack the paper filter material according to a certain width and length.

Abstract

The invention relates to a paper filter material provided with an active adsorption layer, and belongs to the technical field of cigarette preparation. Smoke gas adsorption powder is coated on at least one surface of the paper filter material with the coating amount of 1 to 20 g/m<2>, and then the paper filter material is subjected to embossing, drying and cutting to form cigarette paper filter sticks, wherein the particle size of the smoke gas adsorption powder is 140 to 200 meshes, the smoke gas adsorption powder is mixed with water or alcohol and an edible adhesive to form a sizing material, the sizing material is coated, printed or sprayed to a paper filter material base material, and the mixing mass ratio of the water or the alcohol to the adhesive to the adsorption material is 1:1:(0.1-1). The paper filter material can selectively adsorb volatile and semi-volatile harmful substances in the smoke gas, and under the condition that a filter stick process is not changed, the selective filtration of the smoke gas is realized, and the cigarette pungency is reduced.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter rod preparation, and in particular relates to the preparation of a cigarette paper filter material with an active adsorption layer and its application in cigarettes. Background technique [0002] In order to implement the Framework Convention on Tobacco Control in China, the requirements for low-tar and low-hazardous components in cigarette products have become increasingly stringent in recent years. In response to market development, various cigarette companies have actively developed cigarette filtration technologies, especially new materials in the field of filter rod research, which have greatly improved the flue gas filtration efficiency. [0003] Paper filter is a commonly used special filter. Paper filter material is usually made of wood pulp fiber. It is the earliest, cheapest and simplest material for cigarette filters. It has low cost and high filtration efficiency, especially ...
