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 sugary copolymer composite material for reducing phenol-type substances in cigarette smoke and preparation. The composite material takes cellular materials as carriers, polyanion and hydrophilic polycation are alternately loaded on the cellular materials in a layer self-assembly mode, and the hydrophilic polycation is loaded at the outermost layer of the cellular materials. The composite material can be used for preparing cigarette filters and can be prepared into binary composite type cigarette filters or three-section composite type cigarette filters. In the invention, moisture in the composite material is utilized for selectively reducing phenol-type harmful substances in the cigarette smoke, meanwhile, because a plurality of flavor compounds are insoluble in water, loss of flavor components can be avoided, and the inherent quality of cigarettes is kept.

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 composite material for selectively reducing the content of phenols in cigarette smoke and a preparation method thereof. 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 cigare...
