example 1

[0025] Mix the fiber slurry and sulfuric acid solution with a mass fraction of 50% at a mass ratio of 1:10, soak at room temperature for 10 minutes, and then place it in a constant temperature water bath at 50°C for 30 minutes to obtain a mixed solution. Ionized water, after diluting the acid concentration to 10%, stop the reaction to obtain suspension A, centrifuge at 3000r / min for 15min, discard the supernatant to obtain precipitate A, adjust with 2mol / L sodium hydroxide solution The system was neutral, then centrifuged and washed 4 times repeatedly, discarded the supernatant to obtain the precipitate B, put it in an oven with a temperature of 60°C and dried it to a constant weight to obtain cellulose whiskers; the mass ratio was 1:1 Cellulose whiskers and whisker calcium carbonate are evenly mixed to obtain fillers; in parts by weight, respectively weigh 50 parts of fiber slurry, 20 parts of fillers, and 1 part of combustion enhancer, and mix the fiber slurry in the mixing t...

Abstract

The invention relates to a preparation method of compact ash-wrapping cigarette paper, and belongs to the technical field of papermaking. A crystal whisker material used in the preparation method is long in crystal structure, can bear a certain high temperature, and exerts a framework supporting effect in cigarette paper ash, so that the air-flow impact resistance of the cigarette paper ash is effectively improved. The biological durability of the material is low, so that the material is very easy to degrade in a human body, and the use safety is relatively good. Phosphorus anhydride forms a molten object which is similar to glass during pyrolysis and covers a surface, and a good ash-wrapping effect is achieved. The connecting effect among whisker materials with a fibrous or needlelike structure is enhanced, so that the crystal whisker material does not loose easily, and the ash-wrapping performance of the cigarette paper is improved integrally. Calcium carbonate whiskers are mainly used for improving the appearance of the cigarette paper and improving the air permeability, the smoldering performance and the like of the cigarette paper. In addition, the opacity and the whiteness ofthe cigarette paper can also be improved, and the hand feeling and the flexibility are improved.

Description

technical field [0001] The invention relates to a method for preparing dense ash-packed cigarette paper, which belongs to the technical field of papermaking. Background technique [0002] Cigarette paper, as an important part of the "three papers and one stick" of cigarette accessories, not only carries the key image and connotation of the product, but also has a special and direct impact on smoke because it directly participates in the burning of cigarettes. On the one hand, the burned components of cigarette paper itself are an important part of cigarette smoke, and will be smoked by smokers along with mainstream smoke, so cigarette paper has an important effect on the smoking sensation of cigarette burning; on the other hand On the one hand, the intrinsic quality of cigarette paper will also affect the burning status of cigarettes, and play a decisive role in the ash-packing effect and gray aspect of cigarettes during smoking. [0003] As an important component of cigare...
