Method for preparing cigarette filter with controllable adsorption performance

Abstract

The invention provides a method for preparing a cigarette filter with a controllable adsorption performance. The research and the application of existing cigarette additives mainly focus on the harm reduction function or the flavoring function, the single function can be implemented easily, and related technologies are mature, however, the research of the two fields tend to extremalization, and certain defects exist. The method comprises the steps of adding 5-20 parts of nano-sized activated carbon powder into 100 parts of glycerol triacetate, and mixing uniformly; preparing materials; and uniformly adding the glycerol triacetate containing activated carbon and the like into tows. According to the method for preparing the cigarette filter, the activated carbon does not react with the glycerol triacetate, the activated carbon is just uniformly dispersed inside the glycerol triacetate, and the effect of the glycerol triacetate serving as a plasticizer is not changed, so that the cigarette filter in which the glycerol triacetate containing the activated carbon is added is high in adsorption performance.

Description

technical field [0001] The invention relates to the manufacture of smoke oil filter elements or cigarette holders, in particular to a method for preparing cigarette filter rods with controllable adsorption performance. Background technique [0002] The development of tobacco products has a very close relationship with the application of tobacco additives. As early as the 16th century when Columbus discovered the New World of America, Indians in Mexico had begun to add citrus peel oil to tobacco to enhance the aroma. The U.S. in 1850, Japan in 1920 all appeared the cigarette of fragrance essence respectively, and China began to appear flavoring essence for tobacco such as banana, rum before and after the 1930s. Flavor makes tobacco easier to be accepted by people, and how to ensure that the taste is not damaged while pursuing low tar content, a variety of flavor additives has become the key to the success of tobacco companies. In the context of the global tobacco control ca...

Problems solved by technology

[0006] The other is to place activated carbon in the filter rod, which has the following disadvantages: ①If it is directly added to the filter rod tow, the activated carbon particles are easy to fall off and pollute the cigarette production equipment

②If activated carbon particles are buried in the filter rod in the form of clusters, it will seriously affect the suction resistance of cigarettes; such as "CN201120409136.X one-element activated carbon fiber acetate filter rod", the filter element has a number of cystic activated carbon particles distributed on the axis Group, this technology is to concentrate the activated carbon into a ball and then put it into the center of the filter rod. Although it can reduce the pollution of the equipment and the environment by the activated carbon, it will increase the suction resistance and cause the cigarette smoke to lose a lot of water.

③The above two methods still exist: in order to improve the adsorption performance, the amount of activated carbon added is too much and too concentrated, which will cause serious moisture loss in the flue gas, and the cigarettes are easy to dry when smoking, which will affect the taste of cigarettes; If the method of reducing the amount of activated carbon is used to reduce the impact on flue gas moisture, etc., it will involve changes in the control conditions of a series of process parameters such as tow forming, plasticizer spraying and curing, forming paper wrapping and bonding, especially if corresponding to different For cigarette filter rods of different brands, these processes need to be changed frequently, which will seriously affect the normal production of the enterprise

The main purpose of this technology is to improve the smoking quality of cigarettes. There are too many types of substances added and the production process is complicated. It does not involve the improvement of plasticizers, so as to make the filter rod have suitable adsorption performance and reduce the loss of moisture in the smoke. small research
