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 poly glucosamine hexanedioic acid vinyl ester material for reducing the content of phenol type substances. The composite material is the material which takes a porous material as a carrier and alternately loads polyanions and hydrophilic polycations on the porous material in the way of carrying out self-assembly layer upon layer, and the hydrophilic polycations are loaded on the outmost layer of the porous material, wherein the hydrophilic polycations are poly glucosamine hexanedioic acid vinyl ester hydrochloride. The composite material can be used for preparing cigarette filters and can be prepared into the binary compound cigarette filters or the three-section compound cigarette filters. The poly glucosamine hexanedioic acid vinyl ester material can reduce thephenol type harmful substances in cigarette smoke by utilizing the water selectivity in the composite material; simultaneously, as a large number of flavor organic compounds can not be dissolved in water, the poly glucosamine hexanedioic acid vinyl ester material can avoid the loss of flavor components and keep the inherent quality of cigarettes.

Description

technical field [0001] The invention relates to the technical field of cigarette tar reduction and harm reduction, in particular to a polyglucosamine vinyl adipate composite material for selectively reducing the content of phenols 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 many compo...
