Abstract

The invention discloses high interface adhesion strength nanofiber composite paper and a preparation method and application thereof. The preparation method comprises the following steps: 1, preparing a spinning solution with polymer, additives and solvent, wherein the polymer comprises one or more ingredients out of cellulose diacetate, cellulose triacetate, hydroxyethyl cellulose, polyving akohol and chitosan, and the additives comprise one or more ingredients out of ethanediol, glycerol, pentaerythritol, diacetin, glycerol triacetate, glycerol trioleate, glycerol palmitate and glyceryl stearate; 2, adopting base materials of paper characteristics, conducting electrostatic spinning on the spinning solution which is obtained in step 1, and obtaining the high interface adhesion strength nanofiber composite paper. By means of the high interface adhesion strength nanofiber composite paper, the phenol release amount and NNK release amount in mainstream smoke of a cigarette can be effectively reduced, the phenol release amount is reduced by 11-27%, and the NNK release amount is reduced by 15-30%.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to nanofiber composite paper with high interfacial adhesion strength and its preparation method and application. Background technique [0002] Attaching filters to cigarettes is the most direct and effective means in current cigarette harm and tar reduction technologies. Filters can absorb some harmful components in cigarette smoke, such as intercepting the total particulate matter in mainstream smoke of cigarettes, reducing tar Content, adsorption of harmful substances, thereby reducing the harm to the human body. [0003] The currently commonly used cigarette filters are made of cellulose acetate tow or polypropylene tow, and the cross-sectional size of these tows is generally tens of microns. Increase the specific surface area of ​​the filter to enhance the ability of the filter to absorb harmful substances. [0004] Electrospinning is a simple and convenient technology for ...
