Problems solved by technology

Simple physical adsorption, ion exchange adsorption is less, easy to desorb, causing secondary pollution, and the pore selection of other adsorbents is too small, the particle size of tar particles in the smoke is 0.01-0.3um, and it is easy to smoke during cigarette smoking. Blocking the pores of the adsorbent, resulting in a decrease in the adsorption of aldehydes in the gas phase

Embodiment 1

[0027] After the wood pulp fiber and hemp pulp fiber are disc-grinded, polyethyleneimine containing 20% ​​of primary amino groups is added, and paper is made by wet method. The paper is embossed, and the base paper used is selected according to the suction resistance of the filter rod Width, cut, reduced mouth irritation, improved flavor absorption, and effectively reduced tar and aldehydes.

Embodiment 2

[0029] Papermaking of wood pulp fiber and hemp pulp fiber through disc-grinding fiber pulp, the paper embossing treatment, and then coating the amino compound polythiourea substance, the weight concentration of the coated polythiourea is 2%, and then adjust the width of the cut paper according to the relationship between the suction resistance of the filter rod and the width of the paper used, and use a nozzle rod forming machine to make a filter rod and roll it into a cigarette. After the smoke analysis, the tar and cigarette smoke are effectively reduced. Harmful lower aldehydes.

Embodiment 3

[0031] Papermaking of wood pulp fiber and hemp pulp fiber through the fiber pulp after the disc grinding treatment, the paper embossing treatment, and then coating the compound glycine substance containing amino group, the weight concentration of the glycine coating is 2%, and then According to the relationship between the suction resistance of the filter rod and the width of the paper used, the width of the cut paper is adjusted, and the filter rod is made into a filter rod by a nozzle rod forming machine, and then rolled into a cigarette. After the smoke analysis, the tar and harmful low-level aldehydes in the cigarette smoke are effectively reduced. substance.

Abstract

The invention relates to a paper filter tip capable of reducing aldehydes in cigarette smoke gas and a preparation method thereof. The paper filter tip capable of reducing aldehydes in cigarette smoke gas adopts the paper containing one or a plurality of wood pulp fibers or jute pulp fibers. The paper undergoes a coating process. Through the high water absorption of the paper, compound solution containing amino groups are coated onto the paper; and after drying, cutting and embossing, the paper filter tip is prepared by the paper through a filter tip forming machine. The paper filter tip can effectively reduce formaldehyde by 15 to 40 percent, acetaldehyde by 10 to 25 percent, acrolein by 15 to 30 percent and crotonaldehyde by 10 to 20 percent in cigarette smoke gas.

Description

technical field [0001] The invention relates to a paper mouthpiece stick for reducing aldehydes in cigarette smoke, and a preparation method of the paper filter tip. Background technique [0002] At present, at least 20 kinds of aldehydes and 6 kinds of ketones have been found in the gas phase of cigarette smoke. Some aldehydes and ketones in the gas phase of smoke are the result of direct transfer of tobacco components. Among them, the highest content and harmful to human body are formaldehyde, acetaldehyde, Propionaldehyde, acrolein, crotonaldehyde, furfural and acetone. Some of the volatile carbonyl compounds, especially formaldehyde, acrolein and crotonaldehyde, are toxins of respiratory cilia, which inhibit the removal of lung excretions after inhalation, which can lead to lung diseases. [0003] In order to increase the smoking safety of cigarettes, various methods can be used to reduce harmful aldehydes in cigarette smoke, such as: using filters to filter cigarette s...
