Efficient cigarette filter containing nano bamboo charcoal material

Abstract

The invention relates to an efficient cigarette filter containing a nano bamboo charcoal material. The efficient cigarette filter is characterized in that when cigarette smoke passes through a fiber bundle body of the filter, the smoke is adsorbed on the nano bamboo charcoal particle which is subjected to surface modification and has rich active groups and a high specific area on a fiber bundle, so that toxic and hazardous substances such as various free radicals, part of tobacco tar and the like in the cigarette smoke can be removed through physical and chemical 'adsorption'. A strong oxidant is used for modifying nano bamboo charcoal, and then the nano bamboo charcoal is loaded to a suitable material, so that the adsorptive capacity of the nano bamboo charcoal is greatly improved, the nano bamboo charcoal subjected to modification by the strong oxidant can adsorb hazardous gases in smoke and can chemically decompose the hazardous gases at the same time, and secondary pollution can not be caused. A filter element of the efficient cigarette filter can be used for manufacturing various generalized cigarette filters such as a disposable cigarette filter, a tobacco pipe and the like so as to reduce harms caused by smoking.

Description

【Technical field】 [0001] The invention relates to a cigarette filter tip with a load material, in particular to a cigarette filter tip loaded with a strong adsorption and degradation effect. 【Background technique】 [0002] As we all know, smoking is harmful to health. While satisfying the smokers' addiction, research on reducing the impact of cigarettes on the health of smokers has very good social significance. Among the top ten causes of death among Chinese people in 2001 announced by the Ministry of Health, the top four diseases, namely malignant tumors, heart disease, cerebrovascular diseases, and respiratory diseases, are all related to smoking. Many harmful substances are produced during the burning of cigarettes. Among them, nicotine can cause smokers to rely on tobacco. There are more than 40 substances that are carcinogenic. Many compounds can quickly stimulate and damage the lining of the respiratory tract, increase blood viscosity, and so on. Tobacco smoke contai...
