A polymer-based cigarette filter material with excellent temperature control effect and its preparation method

Abstract

The invention discloses a high-molecular-based cigarette filter material with excellent temperature control effect and a preparation method thereof. Phase change materials and nanoparticles with high thermal conductivity are processed; the polymer material is one of polycaprolactone, polyhydroxyalkanoate, poly 3-hydroxybutyrate, polyglycolide polymer material or Several kinds; the microcapsule phase change material is microencapsulated polyethylene glycol, with polyethylene glycol as the core material and polyacrylonitrile as the wall material. The method of the invention can prepare a low-cost, safe and harmless multi-component polymer-based composite material suitable for cigarette filters with high phase change latent heat and heat transfer capacity. Using it as a new type of cigarette filter can effectively reduce the mainstream smoke of cigarettes, and has the characteristics of low dosage, obvious cooling effect, and significant reduction of harmful substances in smoke.

Description

technical field

[0001] The invention relates to a polymer-based cigarette filter material with excellent temperature control effect and a preparation method thereof. Background technique

[0002] As people pay more and more attention to the issue of "smoking and health" and the global anti-smoking movement continues to rise, it is a very important task to comprehensively reduce the amount of tar and harmful components in cigarette smoke, and it is also an inevitable part of the development of the tobacco industry roads and major issues that governments need to address urgently. Most components in cigarette smoke are toxic to the human body, such as benzene, 2-aniline, 4-aminobiphenyl, aldehydes, volatile nitrosamines, tobacco-specific nitrosamines, benzopyrene, etc., are all possible carcinogenic substances. As a bridge between the smoker and the smoke, the cigarette filter is an important medium for reducing tar and harm. The aerosol particles released during the burning...
