CN101363205A - Molding paper coating for reducing injurants CO, NOx in cigarette smoke - Google Patents

Abstract

The invention relates to a molding paper paint for lowering harmful matters such as cigarette smoke CO, NOx, etc. The invention relates to a tobacco filtering material and provides a cigarette paint which can reduce harmful compositions produced during the combusting process of a cigarette. The paint is made from the materials of polyvinyl alcohol resin solution, tourmaline powder, water-soluble noble metal salt, etc. The paint is coated on high transparent molding paper of the cigarette so as to be made into a functional filter tip. When the paint is used, harmful compositions such as more than 15 percent of carbon monoxide, 25 percent of nitrogen oxide, more than 25 percent of TSNAs, and the like, in smoke can be removed, heavy metal and other harmful compositions can be reduced, simultaneously, the cigarette smoke and the mouth feeling of the cigarette are improved.

Description

Reduce nuisance formed paper coatings such as CO in smoke of cigarettes, NOx

Technical field

The present invention relates to tobacco filtering material, relate in particular to and a kind ofly be worked into cigarette on the forming paper, fall burnt coating with falling evil.

Background technology

After 16 beginnings of the century, tobacco was imported Europe into by America, people have produced different suggestions and arguement to smoking and health problem, particularly Britain Royal Society of Medicine in 1954 has formally delivered the report of " smoking is with healthy ", summarized epidemiological study, tobacco and consumed trend, tobacco components and carcinogenic thereof, smoking many-sided data such as system interpretation of the cause, onset and process of an illness system humans and animals, clearly propose smoking health is harmful to, can cause histanoxia as flue gas CO.Smoking henceforth and health problem have caused worldwide concern, and the cigarette of exploitation low tar, low harm is not only the inexorable trend of tobacco business development and existence, also are State Tobacco Monopoly Bureau about one of development strategy of industry cigarette lowering harm and decreasing coking.

Cigarette filter rod 90% is made up of single acetate fiber and common forming paper at present, the function of forming paper only limits to tow is tied up, gas permeability increases sidewind and reduces cigarette smoke concentration in addition, has diluted harmful components such as tar, nicotine in the flue gas on the macroscopic view.How effectively forming paper to be carried out modification, make it when tow is coated effect, can also effectively reduce the harmful components in the cigarette smoke, give full play to the effect of cigarette supplementary lowering harm and decreasing coking, become tobacco scientific worker research emphasis.On the basis of tobacco research for many years, in conjunction with chemical adsorbing separation science, mineral sciences and smoke chemistry, adopt new method and new technology, multiple sorbing material, alkali metal complex and mineral tourmaline etc. are grouped together, produce nuisance formed paper coatings such as reducing flue gas CO, NOx.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can reduce nuisance formed paper coatings such as CO in smoke of cigarettes, NOx.

The cigarette that the present invention adopts is worked on the forming paper by coating process with reducing harmful components coating such as carbon monoxide, nitrosamine, can play the effect that reduces the cigarette smoke harmful components.

The present invention is formulated by following percentage by weight material:

Polyvinyl alcohol resin 2-10%

Tourmaline powder 5-15%

Water-soluble precious metal salt 3-5%

Attapulgite 5-8%

Medical stone 5-15%

Deionized water 65-80%

Glycerine 0.1-0.5%.

The preparation process of coating of the present invention is:

At first polyvinyl alcohol resin is added deionized water at 60 ℃-80 ℃ (preferably at 70 ℃) mixed dissolutions, the material that adds above-mentioned other proportioning in the polyvinyl alcohol resin liquid of dissolving disperses, grinds nuisance coating such as making cigarette reduction carbon monoxide, nitrosamine.

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

Utilize special process, specific process to make cigarette lowering harm and decreasing coking forming paper function mouth rod, have the following advantages:

1. utilize the permanent spontaneous polarization effect of natural minerals tourmaline, the anion that tourmaline produces moves in air, carry negative electrical charge to the dust that has electric charge in the flue gas, smoke particles etc., electric charge and these particulates are assembled by there is a natural attraction between the sexes, the filtering function of tow is strengthened greatly, reduced the harmful components that cigarette smoke discharges, improved cigarette smoke simultaneously, improve mouthfeel.

2. because water-soluble precious metal salt is that tobacco is used functional additive, can increase efficacy of adsorption, improve the mouthfeel of cigarette, the present invention utilizes the synergy of sorbing materials such as rare earth metal in the water-soluble precious metal salt and medical stone, attapulgite, and effectively absorption reduces the harmful components in the flue gas.

The present invention can remove in the flue gas carbon monoxide more than 15%, nitrogen oxide 25%, TSNAs more than 25%, etc. harmful components.

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

5. 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

Following examples are intended to illustrate the present invention rather than limitation of the invention further, and the present invention may implement by the described arbitrary mode of the technical scheme of summary of the invention.

Embodiment 1:

Polyvinyl alcohol resin 4g, tourmaline 10g, water-soluble precious metal salt (the Guangdong large separation science of profit research institute buys) 5g, attapulgite (chemical industry absorption usefulness, each chemical industry shop is all on sale) 5g, medical stone 10g, deionized water 65.7g, glycerine 0.3g.

Collocation method:

Polyvinyl alcohol resin at first will filling a prescription under normal pressure treats that at 60-80 ℃ of deionized water dissolvings polyvinyl alcohol resin dissolving back is incubated one hour under 30-50 ℃ of normal pressures.

Second step joined water-soluble precious metal salt, tourmaline powder and other material by number carries out high speed dispersion in the polyvinyl alcohol resin liquid 10-20 minutes (1000-1200 rev/mins), makes cigarette with reducing carbon monoxide and nuisance coating.

The existing technological process for coating of this coating utilization is carried out the forming paper coating just make the tar and harm reducing function forming paper, make the function filter rod.

Select the cigarette of this functional shaping paper filter stick coil paper for use, and to compare in the same old way, the flue gas analysis result is as follows;

	Carbon monoxide, mg/cig	Nitrogen oxide, μ mol/cig	Nitrosamine, μ g/cig
				The contrast sample	14.35	2.4195	54.514
