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

A kind of high-efficiency cigarette filter tip that contains the bamboo charcoal nano material

[technical field]

The present invention relates to a kind of cigarette filter with support materials, relate to especially the cigarette filter that a kind of load has strong absorption degradation effect.

[background technology]

As everyone knows, Smoking is harmful to your health, and when satisfying smokers' craving for tobacco, minimizing cigarette has extraordinary social effect to the research of the healthy impact of smokers.In the calendar year 2001 Chinese ten large causes of death that the Ministry of Public Health announces, accounting for four kinds of front four diseases is that malignant tumour, heart disease, cerebrovascular disease, respiratory disorder are all relevant with smoking.Produce many harmful substances in the cigarette combustion process, wherein nicotine can cause the smoker tobacco to rely on, and has 40 many kinds of substances to have carcinogenicity, and chemical compound lot can stimulate rapidly and injure the respiratory tract inner membrance, increase blood viscosity etc.At least the chemical substance that contains three kinds of danger in the smog of tobacco: tar, nicotine and carbon monoxide etc.; Carbon monoxide is transported to the ability that whole body goes to lower red blood cell with oxygen.According to statistics, inhale the people that 15-20 props up cigarette an every day, and it easily suffers from lung cancer, and the probability that carcinoma of mouth or laryngocarcinoma cause death is than 14 times in National People's Congress of non-smoking; It easily suffers from probability that cancer of the esophagus causes death than 4 times in National People's Congress of non-smoking; Die from the probability of carcinoma of urinary bladder and want large twice; Die from cardiopathic probability and also want large twice.The cigarette of enfleuraging is the main cause that causes chronic bronchitis and pneumonia, and chronic lung disease itself also increases terrible pneumonia and cardiopathic danger, and smoking has also increased hypertensive danger.Therefore, seek a kind of technical scheme of effectively in the process of smoking, removing the harmful substance that produces in the smog, have great importance for reducing the harm of smoking to health.

The cigarette filter with adsorption function of the numerous species that arises at the historic moment or mistake filter core, load organic-aqueous gel rubber material is arranged, also have supported porous silicon materials matter, it is the load material with carbon element that a sizable part is arranged, mainly comprise activated carbon, activated carbon fiber, carbon fibre and porous carbon materials etc.Filter tip or core with porous carbon materials is made have preferably effect, but generally can only play the effect of absorption, can't degrade, the possibility that causes secondary pollution is arranged, and ubiquity waste process is complicated, difficulty, equipment requirement is high, the high in cost of production weak point.

It is easy to seek a kind of filter-tip and production process that possesses simultaneously the pernicious gas that absorption and degraded produce in the smog, has broad application prospects.

[summary of the invention]

The present invention is directed to the deficiency of prior art scheme, aim to provide a kind of filter-tip that possesses the pernicious gas that produces in absorption and the degraded smog.

In order to reach the purpose of the pernicious gas that produces in simultaneously absorption and the degraded smog, reduce the injury to smokers' health, the technical program is achieved in the following ways.

Behind loaded with nano bamboo charcoal, strong oxidizer on the suitable material, make overanxious core, with this filter core and different structure and combination, can make various cigarette filters;

The particle diameter of described bamboo charcoal nano is better selection at 10-100nm;

Described strong oxidizer is mainly a kind of in potassium permanganate, potassium chlorate, the ammonium peroxydisulfate;

Described suitable material is fiber or the non-fibrous materials such as acetate fiber, polypropylene fibre, natural cotton;

Above-mentioned filter core prepares by the following method: with nano-bamboo carbon and a certain amount of strong oxidizer be dissolved in 5-20 doubly in the water of (weight ratio) after, with methods such as comprising spraying or immersion bamboo charcoal nano and strong oxidizer are loaded on the suitable material, and drying;

Technique scheme is carried out the modification back loading at suitable material by strong oxidizer to bamboo charcoal nano, greatly promoted the adsorption capacity of bamboo charcoal nano, and can at absorption smog chemical degradation pernicious gas in pernicious gas, can not produce secondary pollution through the bamboo charcoal nano after the strong oxidizer modification.

[specific embodiment]

In order further to understand the present invention, below with reference to embodiment the present invention is made detailed, non-limiting description.
