Preparation method of flame-retardant cigarette paper with functions of reducing CO and maintaining moisture

Abstract

The invention provides a preparation method of flame-retardant cigarette paper with the functions of reducing CO and maintaining moisture, relating to the technical field of cigarette. The preparation method is characterized by adding a water-soluble or alcohol-soluble aid with the functions of reducing CO and maintaining moisture to a flame-retardant material of the flame-retardant cigarette paper, adding poly-molecule capsule water in a flame-retardant material preparation process and then coating the flame-retardant material and the poly-molecule capsule water on base cigarette paper by adopting a method of intaglio printing, thus enabling the poly-molecule capsule water to only exist on a flame-retardant tape, wherein the aid mainly comprises one of the poly-molecule capsule water, sodium sulfide, metallic oxide of magnesium and cerium, citric acid, potassium hydrogen malate, potassium citrate and magnesium salt or the mixture of more of the materials in proportion and the addition of the materials is 0.1-0.9%. The flame-retardant cigarette paper can reduce CO produced when the cigarettes burn, has the function of maintaining moisture and not only has certain safety but also can farthest reduce harms of CO to human bodies.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to a method for preparing flame-retardant cigarette paper with the functions of reducing CO and maintaining moisture. Background technique [0002] US2010866544A discloses a cigarette paper, on which there are some discontinuous strips coated with polysaccharides (such as starch), which can increase the self-extinguishing tendency of cigarettes by reducing the air volume. [0003] EP2002801805A discloses a cigarette with increased self-extinguishing tendency, the cigarette paper contains annular regions coated with a polymer, a polar polymer with a special surface tension that penetrates into the paper structure by , thereby reducing the air permeability of the paper. The surface tension of this polymer exceeds 33mJ / m 2 , this polymer is dissolved in an organic solvent and applied to the cigarette paper by gravure printing so that it penetrates into the cigarette paper. A typi...

Problems solved by technology

[0005] The current flame-retardant cigarette papers all use ordinary cigarette paper as the base material, and a certain amount of film-forming substances are coated on the surface. The coated film-forming substances present a certain pattern on the cigarette paper base material and are discretely distributed. Flame-retardant cigarette paper achieves its flame-retardant effect by reducing the air permeability of the coated area on the cigarette paper, so burning will lead to an increase in the CO content in the smoke, which will cause greater harm to the human body
