Embodiment 1

[0020]Example 1: Preparation of biocellulose nanofibers

[0021]Take the bio-cellulose membrane, freeze-dry it in a vacuum to a water content of less than 5%, and then superfinely pulverize it to produce bio-cellulose nanofiber particles with nanometer-level fiber diameters. It can be found from the TEM electron micrograph that the diameter of the fiber ribbon in the prepared biocellulose nanofiber is between 30-50nm.

Embodiment 2

[0022]Example 2: Preparation of biocellulose nanofibers coated with nano-silica

[0023]Take the biocellulose membrane and soak it in an alkaline solution, soak for 4 hours at a temperature of 90 degrees, cool, and wash with deionized water until it is neutral; then add nano silica with 10% wet weight of the biocellulose under strong magnetic stirring Stir thoroughly and homogenize. Finally, the resulting product is cleaned and then vacuum freeze-dried and dehydrated to a water content of less than 5%, and superfinely crushed.

Embodiment 3

[0024]Example 3: Preparation of biocellulose nanofibers coated with nano alumina

[0025]Soak the biocellulose membrane in an alkaline solution, soak for 5 hours at a temperature of 80 degrees, cool, and wash with deionized water to neutral; then add nano-alumina with 5% wet weight of biocellulose under strong magnetic stirring Stir thoroughly and homogenize. Finally, the resulting product is cleaned and then vacuum freeze-dried and dehydrated to a water content of less than 5%, and superfinely crushed.

Abstract

The present invention provides a filter for cigarettes, and the filter tip contains biocellulose nanofibers in the filter. The diameter of the bio-cellulose fiber is in a nanometer range, the formed pore diameter is also in a nanometer range, the porous structure and certain nanometer pore diameter distribution form a nanometer ultrafine network structure, the surface of the bio-cellulose fiber has a large number of active hydroxyl groups, and when the bio-cellulose fiber is added into a filter tip, harmful substances in cigarettes can be effectively filtered out when a consumer uses the filter tip, such as tar, CO and the like so benefits are brought to the body health of consumers. The novel cigarette filter tip is safe, environmentally friendly, degradable, capable of effectively adsorbing and reducing harmful substances and reasonable in price.

Description

Technical field[0001]The invention relates to the technical field of cigarette preparation, in particular to a cigarette filter tip and a preparation method thereof.Background technique[0002]The cigarette industry has a history of more than 500 years. Smokers smoke because they are addicted to nicotine. In fact, smoking is a major problem that endangers human health. It has been proven that many diseases and smoking are closely related, such as cardiovascular and cerebrovascular and lung diseases. The governments of various countries and the World Health Organization advocate people not to smoke and have adopted a series of tobacco control measures. However, there are still a large number of smokers in the world, and smoking has become a social phenomenon. In the absence of a complete ban on smoking worldwide, efforts to reduce the toxic and harmful components in cigarettes to reduce the harm of cigarettes to people have become a last resort. The American Institute of Medicine encou...
