example 1

[0024]Weigh 20g of nano-titanium dioxide and pour it into a high-temperature furnace, and calcined at a temperature of 550° C. for 45 minutes to obtain calcined nano-titanium dioxide. Wash the calcined nano-titanium dioxide with 15% hydrochloric acid for 3 times to obtain acidified nano-titanium dioxide. The acidified nano-titanium dioxide and The silane coupling agent KH-560 was mixed and stirred for 10 minutes according to the mass ratio of 1:2, and the material was ground and discharged to obtain modified acidified nano-titanium dioxide; 12g of zeolite was weighed and ground for 9 minutes to obtain zeolite powder, and the zeolite was mixed according to the mass ratio of 1:3 The powder and the silver nitrate solution with a mass fraction of 32% were mixed and placed in a beaker and stirred for 12 minutes to obtain a stirred liquid. The pH of the stirred liquid was adjusted to 4 with a nitric acid solution with a mass fraction of 11%, and then the stirred liquid was put into a ...

[0028] Weigh 30g of nano-titanium dioxide and pour it into a high-temperature furnace, and calcined at a temperature of 750° C. for 60 minutes to obtain calcined nano-titanium dioxide. Wash the calcined nano-titanium dioxide with hydrochloric acid with a mass fraction of 15% to obtain acidified nano-titanium dioxide. The acidified nano-titanium dioxide and The silane coupling agent KH-560 was mixed and stirred for 12 minutes according to the mass ratio of 1:2, and the material was ground and discharged to obtain modified acidified nano-titanium dioxide; 18g of zeolite was weighed and ground for 11 minutes to obtain zeolite powder, and the zeolite was mixed according to the mass ratio of 1:3 The powder and the silver nitrate solution with a mass fraction of 32% were mixed and placed in a beaker and stirred for 16 minutes to obtain a stirred liquid. The pH of the stirred liquid was adjusted to 6 with a nitric acid solution with a mass fraction of 11%, and then the stirred liquid w...

Abstract

The invention specifically relates to a preparation method for antibacterial hydrophobic tipping paper, belonging to the technical field of preparation of cigarette materials. The preparation method for the antibacterial hydrophobic tipping paper comprises the following steps: with modified starch as a bridge, separately bonding the modified starch with modified acidified nanometer titanium dioxide, self-made silver-carrying zeolite and self-made ground pulp; and preparing the antibacterial hydrophobic tipping paper under the action of calcium carbonate and polyvinyl alcohol. According to theinvention, chloropropylene oxide and succinic anhydride are used for modification of starch so as to improve the water resistance of the tipping paper; then nanometer titanium dioxide is subjected tocalcining and acidolysis so as to form acidified nanometer titanium dioxide, so the antibacterial properties of the tipping paper are enhanced; a silver nitrate solution is used for modification of zeolite with a porous structure, so the antibacterial properties of the tipping paper are further enhanced; and then the modified acidified nanometer titanium dioxide is mixed with the self-made silver-carrying zeolite, and ester groups are grafted onto the surface of the mixture under the action of microbes to endow the mixture with waterproof capability, so the tipping paper is further improved inwater resistance. The prepared tipping paper has good application prospects.

Description

technical field [0001] The invention relates to the technical field of cigarette material preparation, in particular to a method for preparing antibacterial and hydrophobic tipping paper. Background technique [0002] my country is a big country in tobacco production and consumption. With the continuous improvement of people's living standards, the number of smokers is increasing year by year and showing a younger trend, and people's demand for tobacco is also increasing. [0003] Tipping paper, also known as tipping paper, is the paper (often cork-colored or opaque white) used to wrap the filter tip and glue the filter rod to the end of the tobacco rod. Tipping paper is a kind of packaging material for cigarettes. It is specially used as the outer packaging of filters in cigarette factories. It is a special industrial paper and mainly plays a role in improving the appearance of cigarettes. [0004] However, cigarette smoke contains a variety of toxic substances. After smok...
