Abstract

The invention relates to a tobacco filter material, and provides a cigarette coating capable of reducing harmful ingredients generated in the process of cigarette combustion. The coating is prepared from materials such as resin liquid, negative ion powder and the like. The coating is coated on cigarette forming paper or sprayed on cut tobaccos to form a mouthpiece rod. The coating can remove harmful ingredients such as 10 percent of carbon monoxide, 30 percent of amine, 10 percent of crotonic aldehyde, 15 percent of phenol and the like in smoke, and improve the irritation of the cigarette smoke and mouthfeel simultaneously.

Description

Cigarette harm reduction coating

Technical field:

The present invention relates to tobacco filtering material.

Background technology:

According to the promise of Chinese Government about " Framework Convention on Tobacco Control ": 7 harmful components weighted values met international standards substantially in 2011, and the average tar content of cigarette that China in 2011 produces will be reduced to 10 milligrams/.Therefore, developing low type cigarette and the relevant auxiliary materials of endangering safety of low tar is the key subjects of China's tobacco business, is very arduousness and a urgent task.Sum up on the basis of experience and achievement for many years,, multiple sorbing material and Chinese herbal medicine are grouped together, make smoke harm reduction coating by using new method and new technology.

The effect of China's forming paper only limits to tow is tied up at present, and gas permeability increases sidewind and reduces cigarette smoke concentration in addition, does not have the effect that reduces various harmful components, just dilutes tar in the flue gas, nicotine and various harmful components.

Summary of the invention:

The purpose of this invention is to provide and a kind ofly can reduce cigarette produces harmful components in combustion process coating.

This cigarette harm reduction special coating of the present invention is worked on the forming paper or is sprayed directly on on the tow when the filter tip moulding by coating process, just can play the effect of harm reduction.

Technical solution of the present invention is to be formulated as follows by following percentage by weight formula rate:

Polyvinyl alcohol 2-10%

Negative ion powder 5-10%

Medical stone 5-10%

Fructus amomi 3-5%

FRUCTUS AMOMI ROTUNDUS 3-5%

Subprostrate sophora 2-6%

Deionized water 65-80%

Glycerine 0.1-0.5 ‰

Process for preparation;

At first fructus amomi, FRUCTUS AMOMI ROTUNDUS, three Chinese herbal medicines of subprostrate sophora are processed into 100 purpose powder in this case ratio;

Again polyvinyl alcohol is added water and be mixed into dissolving at a certain temperature, in the polyvinyl alcohol liquid of dissolving, add negative ion powder, medical stone powder and fructus amomi, FRUCTUS AMOMI ROTUNDUS, three 100 purpose Chinese herbal medicine powders of subprostrate sophora and disperse, grind and make cigarette harm reduction coating.

The existing process of above-mentioned coating utilization is applied on the forming paper, perhaps is sprayed on and makes the multi-functional filter rod of harm reduction on the tow.

Utilize existing technology, existing method to make cigarette harm reduction forming paper or harm reduction filter rod, have the following advantages:

1, can remove harmful components such as carbon monoxide 10% in the flue gas, amine 30%, crotonaldehyde 10%, benzene sweet smell 15%.

2, utilize negative ion powder in air, to move and be " Z " font principle, and carry negative electrical charge to give dust, smoke particles and moisture etc., electric charge combines with these particulates and conglobulates, the filtering function of tow is strengthened greatly, realize reducing harmful components and other harmful components, utilize Chinese herbal medicine to decompose the excitant that harmful components are improved cigarette smoke simultaneously, improve mouthfeel.

3, for the cigarette designer provides safer cigarette supplementary product, reach minimum harmfulness to the smoker.

4, promote the reform progress of China's cigarette filter material, meet or exceed international standard, improve the interior quality of Chinese style cigarette.

The specific embodiment:

Prescription (unit: gram)

Polyvinyl alcohol 4g, negative ion powder 8g, medical stone 5g, fructus amomi 3.5g, FRUCTUS AMOMI ROTUNDUS 3.5g, subprostrate sophora 5g, deionized water 70.7g, glycerine 0.3g.

Compound method:

Chinese herbal medicine fructus amomi, Dou guan benevolence at first will filling a prescription, subprostrate sophora Yong Dian Mo Mo become powder (1000 rev/mins) powder to hide absolutely by 100 mesh sieves.

Second polyvinyl alcohol that will go on foot in will filling a prescription under normal pressure dissolves in 60-80 degree deionized water, treats that polyvinyl alcohol dissolving back is incubated one hour under 30-50 degree normal pressure.

The 3rd step joined grass meal in negative ion powder, medical stone powder and fructus amomi, FRUCTUS AMOMI ROTUNDUS, the subprostrate sophora by number carries out high speed dispersion 10-20 minute (1000-1200 rev/min) in the polyvinyl alcohol liquid, grind once (600-1200 rev/min) by sand mill, make cigarette harm reduction coating.

The existing technological process for coating of this coating utilization is carried out the forming paper coating just make the harm reduction functional shaping paper, perhaps be sprayed on and make harm reduction function filter rod on the tow.

Claims (1)

1. cigarette harm reduction coating is characterized in that this coating prepared by following percentage by weight formula rate:
