Description

Paper for paper filter stick, filter stick and preparation method for reducing phenolic substances in cigarette smoke

technical field

The invention belongs to the technical field of cigarette filter preparation, and relates to paper containing diacetate fiber functionalized with amine substances, a paper filter stick and a preparation method.

Background technique

Cigarette filter rods are the main cigarette accessories in the tobacco industry, and are an important measure to reduce the harm and tar of cigarettes. Pure wood pulp or hemp pulp paper filter rods have the advantages of good filtration performance and low price. However, paper filter rods also have thermal collapse, dry smoke, and obvious paper smell during cigarette smoking. shortcoming. The currently widely used cellulose diacetate tow filter rod overcomes the shortcomings of ordinary paper filter rods in terms of appearance and odor absorption, but compared with paper filter rods, it also has the disadvantages of higher cost and lower damage and coke reduction performance.

Along with the problem of smoking and health more and more people pay close attention to, the harmfulness problem of the cigarette that tobacco industry also is committed to solving all the time, therefore, the research of new paper filter stick has been subject to people's attention again. In the method disclosed in the Chinese patent application CN101032347A, a method for manufacturing the paper required for the paper nozzle rod with the slurry containing cellulose acetate is proposed, which provides a new idea for the research of the paper for the new paper nozzle rod, but the preparation contains Acetate paper does not exhibit superior performance over ordinary paper rod paper and requires specially modified forming machines to process filter rods.

It is generally believed that the influence of paper filters on cigarette smoking is partly due to the low interception efficiency of paper filters on phenolic substances in smoke, and phenolic substances are one of the main harmful components in smoke. Phenol is a recognized toxic chemical substance. Once absorbed by humans, it will accumulate in various organs and tissues. It is difficult to get rid of it from the body. It will combine with the protein in the cell plasma to form an insoluble protein, which will cause the cell to lose its activity. Phenol has toxic effects on the nervous system, urinary system, and digestive system. When the phenol in the body reaches a certain amount, it will destroy liver cells and kidney cells, causing chronic poisoning, causing dizziness, headache, rashes, and mental disorders in different degrees. Anxiety, diarrhea and other symptoms. Therefore, effectively improving the retention efficiency of paper filter rods for phenols is one of the important means to improve the usability of paper filter rods.

Contents of the invention

The purpose of the present invention is to provide a paper material for cigarette filter rods, which can effectively reduce harmful components in cigarette smoke, especially tar and phenolic compounds, and improve the effect of ordinary paper filter rods on cigarette smoking. Influence.

Another object of the present invention is to provide a simple and practical preparation method for the above-mentioned paper material for cigarette filter rods.

Another object of the present invention is to provide a cigarette filter rod made of paper material for the cigarette filter rod.

The present invention is achieved through the following embodiments.

A paper filter stick paper for reducing phenolic substances in cigarette smoke is paper containing diacetate fiber, and the diacetate fiber is functionalized with amine substances; the diacetate fiber functionalized with amine substances The mass content is 10-60%, and the rest is one or more of wood pulp fibers or hemp pulp fibers.

The mass content of the amino compound in the diacetate fiber functionalized by the amine substance is 1-10%.

Amines include one or more of ethylenediamine, diethanolamine, isopropanolamine, acrylamide, methacrylamide, triethylenediamine, cyclohexylamine, polyacrylamide, polyethyleneimine, and chitosan Several kinds.

The functionalization process of diacetate fiber is as follows: the long diacetate fiber is disc-grinded into short fibers, then soaked in amine solution, and then washed with deionized water.

The basis weight of the diacetate fiber paper functionalized with amines is 20-50 g/m ² .

A paper preparation method for paper filter rods for reducing phenolic substances in cigarette smoke: First, long diacetate fibers are disc-grinded into short fibers, and amines are used to functionalize the surface of diacetate fibers with amine groups, and the functionalized The cellulose diacetate is mixed with the disc-refined wood pulp or hemp pulp, and then prepared into paper by wet or dry process.

The use of amines to functionalize the amine groups on the surface of diacetate fibers involves immersing the diacetate fibers in a solution of amines.

The mass concentration of the amine substance solution is 10%-40%.

The diacetate fiber is soaked in the amine substance solution at 20-100 DEG C for 1-5 hours.

The diacetate fiber soaked in the aqueous solution of amines is mixed with the disc-ground wood pulp or hemp pulp in a weight ratio of 1:1-5.

A kind of paper filter stick paper for reducing phenolic substances in cigarette smoke is paper containing diacetate fiber, the diacetate fiber is functionalized by amine substances, and the diacetate fiber functionalized by amine substances The mass content of fibers in the paper is 10-60%, and the rest is one or several kinds of wood pulp fibers or hemp pulp fibers. Emboss and cut the paper for filter rods, and directly use the commonly used nozzle rods at present. Forming machine for forming process.

After the filter stick is embossed with paper, it is cut into narrow strips with a width of 15-30 cm.

The filter stick, which also includes a composite filter stick, refers to a cigarette filter stick made of diacetate cellulose paper functionalized with amine substances, which is compounded with other types of cigarette filter sticks.

The composite filter rod is composed of a paper filter rod and an ordinary acetate fiber filter rod according to the length ratio of 0.5-5:0.5-5.

The cigarette filter rod has all the functions and appearance features of an ordinary paper filter rod, and triacetin or other cellulose acetate plasticizers may not be added during the molding process of the filter rod.

The beneficial effects of the present invention are: the paper filter rod prepared by adopting the diacetate fiber functionalized with amino groups, and then the paper filter rod not only has all the functions and external characteristics of the paper filter rod, but also can significantly reduce cigarette smoke The phenolic substances in the cigarette improve the safety of cigarettes, improve the taste of cigarettes, improve the sensory quality of ordinary paper filter sticks, and overcome the thermal collapse of paper filter sticks during cigarette smoking. The smoke has the disadvantages of dryness and obvious paper smell, and it can also significantly reduce the tar in the cigarette smoke. The process is simple, the cost is low, and the practicability is strong. Compared with adding the amine compound directly into the paper, the amount of the amine compound is less, which saves the cost and also reduces the influence of the free amine compound on the smoking taste of the cigarette.
