Problems solved by technology

[0002] At present, cigarette filter rods in my country are mainly made of cellulose acetate fibers and polypropylene fibers, and the production process is complicated and the cost is high.
Although cellulose acetate fiber is derived from wood, its degradation cycle is still as long as 4 years, and the degradation time is relatively long; while the raw material for the production of polypropylene fiber comes from petroleum, which is a non-renewable resource and does not conform to the production concept of environmental protection and sustainable development.
On the other hand, the existing filter rods for cigarettes have a single structure, and the ability to remove harmful substances such as tar, phenol, hydrogen cyanide and crotonaldehyde is limited, and it is necessary to further improve its purification effect.

preparation example Construction

[0032] Specifically, the filter material 5 includes a fiber net and a hybrid filling material located in the fiber net, and the hybrid filling material includes HNTs, ferric oxide and sodium chloride crystals. The preparation method of the hybrid filling material comprises the following steps:

[0033] S1: Prepare 24-37g / L sodium chloride solution, 10-40g / L ferric chloride solution and 0.6%-0.9% polyvinyl alcohol solution;

[0034] S2: Mix the above-mentioned sodium chloride solution, ferric chloride solution and polyvinyl alcohol solution in a volume ratio of 5:1:0.4 to prepare a soaking solution;

[0035] S3: adding HNTs to the soaking solution in a weight ratio of 1:5 to the soaking solution and stirring, then adjusting the pH to 8-9 with 14% ammonia water, and then continuing to stir for 3 hours;

[0036] S4: The reaction product is separated by filtration, dried, ground, and calcined at 400° C. for 2 hours, so that ferric oxide is attached to the surface of HNTs, and sod...

Abstract

The invention discloses an environment-friendly filter stick which comprises a coating layer, a first filter section and a second filter section. An end of the first filter section is connected with an end of the second filter section, and the coating layer is coated on the peripheral walls of the first filter section and the second filter section; the second filter section comprises a shell and filter materials, and an accommodating cavity is arranged in the shell and is filled with the filter materials. The invention further discloses a method for producing the environment-friendly filter stick. The method includes steps of soaking, filling, solidifying, assembling and the like. The environment-friendly filter stick and the method have the advantages that cellulose acetate fibers and polypropylene fibers are replaced with plant fibers, accordingly, the degradation cycle of the environment-friendly filter stick can be shortened, consumption of wood and petroleum resources can be reduced, and the environment-friendly filter stick and the method are environmentally friendly; harmful substances in smoke can be removed by added hybrid filling materials, and accordingly harm on the health of consumers due to tobaccos can be reduced.
