Abstract

The invention discloses a preparation method of modified electronic cigarette floc filler fiber, specifically a method for modifying electronic cigarette floc filler by antibacterial substances and mesoporous materials, mainly by oxidizing and polymerizing antibacterial agents containing phenolic groups On the surface of the fiber, it is connected by a coupling agent, and a mesoporous material is added to the fiber floc to finally obtain an electronic cigarette floc with antibacterial properties and high adsorption / desorption capacity. The preparation method of the present invention is simple and reliable, and the prepared electronic cigarette floc filler has a rough surface, a large amount of mesoporous materials are adsorbed on the surface, the adsorption / desorption property is enhanced, and the antibacterial performance is good.

Description

technical field [0001] The invention belongs to the technical field of electronic cigarette materials, and in particular relates to a method for modifying rough porous surface and antibacterial electronic cigarette flocs. Background technique [0002] E-cigarette is a product that atomizes the e-cigarette solution through an atomizer to deliver nicotine or other substances to the respiratory system. The flocculent filling of electronic cigarettes is the part of e-cigarettes that stores e-liquid, which has an important impact on the e-liquid content, reliability, and taste of an e-cigarette. It is required to have good adsorption / desorption performance for nicotine, solvents, flavors and fragrances in e-liquid, and it is not easy to breed bacteria during use, and it can withstand high temperature. [0003] At present, the main materials of floc fillers in electronic cigarettes include polyester fibers, polylactic acid fibers, cellulose, nylon, polypropylene fibers, polyureth...
