Cigarette filter rod with added graphene oxide-loaded filter

technical field

The utility model belongs to the technical field of tobacco filter rod production, in particular to a cigarette filter rod added with a filter screen loaded with graphene oxide. the

Background technique

With the continuous enhancement of consumers' health awareness, the situation of tobacco control has become increasingly severe, and at the same time, it is also urging the continuous development of cigarette technology. In recent years, a variety of new cigarette tar and harm reduction technologies have been developed and applied, such as new punching technology for tipping paper, new cigarette paper, and new filter additives. It is realized by physical methods such as collision and interception of aerosol particles in the air.

A commonly used method in the existing flue gas harm reduction technology is to add various additives to the filter rod to physically or chemically adsorb the flue gas to reduce the harmful components in the flue gas, but this method generally has a large amount of additives, Defects such as limited contact area. Among various harm reduction materials, graphene oxide is a commonly used and widely reported additive material. Graphene oxide is a kind of modified graphene after electrochemical or acid treatment. In addition to the excellent characteristics of ordinary graphene, its surface also contains abundant hydroxyl, carboxyl and carbon-oxygen functional groups, which are easy to combine with hydroxyl, amino and carboxyl groups. Such polar groups form hydrogen bonds, so graphene oxide has a good adsorption effect on conjugated molecules, bases and aldehyde and ketone molecules. As reported in CN201310001588.8, graphene materials are loaded onto carbon fiber or cellulose acetate carrier, and the carrier is added to the filter by using the existing binary filter manufacturing method in the industry to make a composite filter. Good damage reduction can be achieved in very few cases. However, because graphene oxide materials must rely on specific adsorbent materials to play a good role in reducing harm and coke, and the existing adsorbent materials often have certain disadvantages such as excessive suction resistance and difficult suction, so further research is still needed. Improve. the

Contents of the invention

The purpose of the utility model is to provide a cigarette filter rod added with a filter screen loaded with graphene oxide. The graphene oxide filter in the filter rod is loaded in the filter screen. The location of the mesh can better solve the problem of filter rod suction resistance.

Concrete technical scheme of the present utility model is as follows.

A cigarette filter rod added with a filter screen loaded with graphene oxide, including a filter rod tow, a filter screen, and a filter rod forming paper, wherein the filter rod forming paper wraps the filter rod tow to form a filter rod, and the filter screen is in the filter rod Place one piece or multiple pieces equidistantly in the middle of the filter rod tow;

Graphene oxide material is loaded on the filter net; the graphene oxide material is loaded on the filter net through processes such as spraying, coating or soaking.

The material of the filter screen is a cellulose mesh or other absorbent material mesh.

The mesh size or number of the filter screen can be adjusted according to the design of cigarette draw resistance.

The filter mesh can be placed at the junction of the base rods through a binary or multi-component filter rod compounding process or directly placed in the center of an ordinary acetate filter rod.

The number of the filter screen in a single cigarette filter rod is preferably 1-2.

The cigarette filter rod added with the filter screen loaded with graphene oxide described in the utility model can be used alone or combined with other filter rods.

In the utility model, the size of the filter screen is controllable, there are various ways of loading graphene oxide, and the load capacity is easy to control. It is an excellent load carrier for harm-reducing and tar-reducing adsorbents; Therefore, it can better adjust the draw resistance of the cigarette filter rod. By adjusting and designing the position of the filter screen in the filter rod, while making the mainstream smoke of the cigarette fully contact with the graphene oxide material and intercepting harmful components, the adjustment of the filter rod's suction resistance can be better realized. The equipment requirement is simple, easy to implement, and can be prepared and used in combination with other types of cigarette filter rods, so it has good practical value.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

Example

As shown in Figure 1, the shape of the filter net loaded with graphene oxide adsorption material is a regular circle, but according to the needs or process, the filter net can also be in other shapes or irregular shapes.

Taking a specific specification as an example, the material of the filter is cellulose mesh, the diameter of the mesh is about 0.2mm, the amount of graphene oxide loaded on a single filter is about 0.5mg, and the graphene oxide is loaded on the filter mesh by soaking .

As shown in Figure 2, a cigarette filter rod with a filter screen loaded with graphene oxide is added, including a filter rod tow 1, a filter screen 2, and a filter rod forming paper 3, wherein the filter rod forming paper 3 wraps the filter rod tow 1 to form The filter rod, the filter screen 2 is placed in the middle of the filter rod tow 1 in a single piece or multiple pieces equidistantly in the filter rod;

The filter screen is as above and shown in FIG. 1 . In this embodiment, there are two filter screens 2, which are respectively located at one-third of the length of a single cigarette filter rod.

Smoking experiments show that under the same amount of graphene oxide added, compared with the uniform distribution of graphene oxide in the filter rod tow, the cigarette filter rod provided by the utility model has a smaller suction resistance and can filter mainstream smoke. The effect is equivalent or even better, and thus has a better technical effect.

It needs to be emphasized and explained that, according to the requirements of harm reduction and coke reduction effect and cost, the mesh size and quantity of the filter can be adjusted according to the design of cigarette draw resistance, and the placement method of the filter rod can also be single piece or multiple pieces, etc. Variety of ways. Moreover, the cigarette filter rod provided by the utility model with added graphene oxide-loaded filter screen can be used alone, or can be placed at the joint of the base rod through a binary or multi-element filter rod composite process or directly placed in ordinary acetate fiber The central position of the filter rod allows it to be used in combination with other types of filter rods, so it can be used in a wider range and has better promotion and application value. the
