Problems solved by technology

Chinese patent ZL200710162960.8 discloses mixing extracts of some Chinese herbal medicines into cut tobacco as a method to reduce harmful phenolic substances in cigarette smoke, but this method may affect the normal combustion of cut tobacco and affect the taste of smoke , and even increase other harmful ingredients
Chinese patent application CN200910307638.9 discloses that calixarene in solid powder form is directly added to cigarette filters as an additive, which can reduce phenol by about 40%, but the toxicity of calixarene itself has yet to be considered
In addition, Chinese patent application CN200810031589.6 and Chinese patent application CN200710034453.6 respectively disclose ionic liquids and metal oxides as additives for filter rods, and have a certain effect of reducing phenols; however, the preparation process of these two substances is relatively complicated, and The health and safety of filters added with ionic liquids or metal oxides needs further investigation

Abstract

The invention discloses a sugar-containing bipolymer additive for reducing phenol substances contained in cigarette smoke. The additive takes a granular porous material as a carrier and granular porous material is loaded with hydrophilic polycations; and the hydrophilic polycations are sugar-containing bipolymers. If the sugar-containing bipolymer additive can be used for preparing a cigarette filter, the harmful phenol substances contained in the cigarette smoke can be reduced selectively by utilizing moisture contained in the sugar-containing bipolymer additive; in addition, because multiple fragrant organic compounds are water-insoluble, the invention reduces the harmful phenol components contained in the cigarette smoke and can also possibly prevent fragrant components from being lost, thereby maintaining the internal quality of cigarettes.

Description

technical field [0001] The invention relates to the technical field of tar reduction and harm reduction of cigarettes, in particular to a sugar-containing binary copolymer additive for selectively reducing the content of phenolic substances in cigarette smoke. Background technique [0002] For a long time, the world tobacco industry has always attached great importance to reducing the harm and tar of cigarettes. In recent years, WHO has made specific regulations on the control of harmful components in smoke, which have received positive responses from countries all over the world. Aiming at various harmful components in cigarette smoke, researchers have developed a variety of harm reduction technologies, among which the modification of cigarette filters is one of the most effective means of harm reduction; by adding or compounding nanomaterials, Polymer materials and biological materials can effectively reduce some harmful components of cigarette smoke. [0003] There are ...
