Method for preparing ash packing cigarette paper

Abstract

The invention discloses a method for preparing ash packing cigarette paper. The method comprises the following steps of: adding 5 to 30 weight percent of whisker material and 0 to 25 weight percent of calcium carbonate filler into wood pulp fiber size in the pulping section of the cigarette paper production process, and performing short cyclic homogenization, net part forming, squeezing and drying on the prepared pulp to form raw paper; preparing aqueous solution of a hot melt substance and a combustion improver in the sizing section, adding 0.2 to 1.0 weight percent of hot melt substance and1.5 to 3 weight percent of combustion improver on the raw paper, and performing secondary drying. Whisker materials are one or more than one from calcium carbonate whisker, calcium sulfate whisker, magnesium sulfate whisker, magnesium oxide whisker, alumina whisker, zinc oxide whisker and magnesium hydroxide whisker. The hot melt substance is one or more than one of potassium dihydrogen phosphate, sodium dihydrogen phosphate, sodium hexametaphosphate, and potassium hexametaphosphate. The prepared ash packing cigarette paper can effectively improve the ash packing performance of cigarette ash in the smoking process, solves ash dispersion, floating and drop, improves the ash holding length of cigarettes during smoking, and has high using safety.

Description

technical field [0001] The invention relates to cigarette paper and its auxiliary materials and production process. Background technique [0002] In order to improve the smoking environment of cigarettes and reduce the phenomenon of ash floating and falling during cigarette smoking, it is necessary to add some non-traditional materials in the production process of cigarette paper. At present, five kinds of substances are mainly added to improve the ash-coating performance of cigarette paper: 1) silicate man-made fibers, such as glass fibers; 2) mineral fibers, such as asbestos; 3) carbon fiber materials; 4) synthetic or natural high Molecular materials; 5) Magnesium, aluminum oxides or hydroxides or their organic acid salts. Although the use of this type of material can improve the ash-packing performance of cigarette paper, there are still the following technical defects: 1) silicate man-made fibers and mineral fibers have long biological persistence, and once inhaled into...

AI Technical Summary

Problems solved by technology

Although the use of this type of material can improve the ash-packing performance of cigarette paper, there are still the following technical defects: 1) silicate man-made fibers and mineral fibers have long biological persistence, and once inhaled into the human body, they are difficult to degrade in a short time. When the macrophages in the body cannot be processed, it is very easy to induce cancer in human tissues and organs; 2) Adding carbon fiber materials has a great impact on the whiteness of cigarette paper, and the price is relatively expensive, and the application cost is high; 3) Although polymer materials can Adhesion to cigarette paper ash, but its thermal stability is poor, not high temperature resistant, so its effect on improving cigarette paper ash is limited; 4) Magnesium and aluminum compounds mainly play the role of reducing cigarette smoke, although to a certain extent It can improve the ash wrapping performance of cigarettes, but the ash wrapping effect is not obvious
