Abstract

The invention relates to an ash wrapping aid, a preparation method and ash wrapping cigarette paper, wherein the ash wrapping aid is chitosan-modified iron phosphate nanoparticles, and a sizing agentprepared from the chitosan-modified iron phosphate nanoparticles is coated on the surface of the cigarette paper in an offline coating manner, and the improved ash wrapping cigarette paper is obtainedafter drying. According to the technical scheme, chitosan is used for carrying out surface modification on nano iron phosphate, the dispersity of nano particles can be improved, the uniformity of material dispersion in the coating process is guaranteed, meanwhile, the iron phosphate particles are attached to the surface of cigarette paper, and the powder stripping phenomenon is avoided. Accordingto the technical scheme, the CTS-FePO4 nanoparticles are used as the ash coating auxiliary agent for the first time, so that the preparation process is mild, environment-friendly and easy to operate;the ash coating performance of the paper can be remarkably improved after the CTSFePO4 nanoparticles are coated on the cigarette paper.

Description

technical field [0001] The invention belongs to the technical field of cigarette accessories, in particular to the technical field of cigarette paper, in particular to a chitosan-modified iron phosphate (CTS-FePO 4 ) Nanomaterials are added to cigarette paper to improve the ash-wrapping capacity of cigarette paper. Background technique [0002] In recent years, the ash-coating performance of cigarette paper has been paid more and more attention by cigarette processing enterprises. The ash-coating effect of cigarettes after burning will directly affect the smoking experience of consumers. Cigarettes with good ash-coating performance will have a beautiful smoke column after burning, while cigarettes with poor ash-coating performance will cause serious ash fall during smoking, which will pollute the environment and affect consumers' recognition of cigarette brands. Therefore, cigarette paper manufacturers often add ash-coating additives during production and processing to impr...
