Problems solved by technology

When the patent uses potassium chlorate as the porogen, potassium chlorate needs to be heated above 400°C to decompose, and when the temperature of cigarette paper reaches 400°C, the temperature in the burning zone of cigarette shreds is generally above 500°C. Under certain conditions, cigarette shredded tobacco tends to produce more tar when burned, which is not conducive to the reduction of tar content in cigarette smoke
[0004] Most of the research on reducing the tar content of cigarettes in the existing public technology focuses on improving the air permeability of cigarette paper, but when the air permeability of cigarette paper reaches 80 cu, further improvement of the air permeability of cigarette paper has no significant effect on reducing the tar content of cigarettes

Abstract

The invention provides tar reduction type cigarette paper and a preparation method thereof. An adhesive layer of the tar reduction type cigarette paper contains the following components: modified heat-conducting activated carbon, potassium chlorate and a catalyst, the specific surface area of the modified heat-conducting activated carbon is 900-1000m < 2 > / g, and the heat conductivity coefficient is 5-8w / (m * K); the catalyst is manganese dioxide or copper oxide. The modified heat-conducting activated carbon, the potassium chlorate and the catalyst in the adhesive layer of the tar reduction type cigarette paper have a synergistic effect, and under the combined action of the modified heat-conducting activated carbon, the potassium chlorate and the catalyst, the temperature of a combustion area of a cigarette is reduced, the air permeability of the cigarette paper can be improved, aerobic combustion of the cigarette is promoted, and then the amount of tar generated in the combustion process of the cigarette is reduced.

Description

technical field [0001] The invention belongs to the technical field of cigarette paper production, and in particular relates to a reduced-coke cigarette paper and a preparation method thereof. Background technique [0002] The remaining part of cigarette smoke particles except water and nicotine is called tar. It is generally believed that the harmful components in cigarette smoke are mainly concentrated in tar. Cigarette sticks are composed of shredded tobacco, cigarette paper and filters, among which shredded tobacco is the most important part. When the cigarette is lit, the shredded tobacco and the cigarette paper burn together, and a series of complex chemical reactions occur between the shredded tobacco and the chemical components in the cigarette paper, thereby forming cigarette smoke. Tar is a complex compound composed of various hydrocarbons and hydrocarbon oxides, sulfides and nitrides, which are produced by the incomplete combustion of organic substances in ciga...
