Abstract
The present invention utilizes sepiolite to make the method for cigarette filter tip materials.The most of filtering material that uses all is the acetate fiber of dependence on import at present, and it is the cost height not only, and filter effect is bad.The present invention makes filtering material with spraying process or mixing method.Spraying process is that sepiolite is sprayed on wrinkling moulding on the thin paper, or sepiolite is sprayed on moulding on acetate fiber, the polypropylene fibre.Mixing method is mixed and made into the curl moulding with sepiolite and paper pulp.
The present invention has good filtration effect, can make content of coal tar in smoke be lower than international standard (12mg/g), and cost is low, and technology is implemented simple, advantages such as remarkable in economical benefits.
Description
The invention belongs to cigarette filter material and make the field.
Sepiolite is a kind of have inside and outside pore structure, specific area 470m
2The nontoxic natural simple ore thing of/g.Polar molecule, molecule that diameter is little there is very strong chemo-selective absorption, as absorption to harmful substances such as the carbon monoxide in the flue gas, carbon dioxide, nitrile, acetone, methacrylaldehyde.Add the filter tip that cellulose is made with sepiolite, can adsorb the pernicious gas in the flue gas well; The hole that big molecule and Molecularly Imprinted Polymer then are filtered in the mouth stops, has improved filter effect.The filtering material of this compound proportioning, can make that coal tar content eases down to below the international standard (12mg/g) in the flue gas, and make content of harmful gas such as polar molecule carbon monoxide, carbon dioxide, nitrile, acetone, methacrylaldehyde drop to very low degree, alleviate smoker's (comprising the involuntary smoker) extent of injury, be of value to people's physical and mental health.Sepiolite to medium nonpolarity molecule such as methylfuran, to methylfuran, cover aromatic substance adsorptivity such as alkene a little less than, thereby improved the ratio of this material in flue gas, strengthened smoke perfume, more be subjected to consumer's welcome.
Can form production capacity at present, and the used materials of the cigarette filter overwhelming majority of listing are acetate fibers, have seldom that part is to use polypropylene, the boundling moulding.The filter tip that these materials are formed, general is played barrier effect to solid particle bigger in the flue gas and drop; And it is relatively poor to the liquid resistance filter effect of granule gas, gasification.Can reduce to medium level (20-25mg/g) by the content of coal tar in the flue gas behind this filter tip; Relatively poor to gasified liquid filter effects such as pernicious gas carbon monoxide, carbon dioxide, nitrile, acetone, methacrylaldehyde, this health to people is disadvantageous.Existing market also has a kind of lignose to add the composite filter-tip of activated carbon, can make in the flue gas coal tar content can reduce to the low level (15mg/g) that waits, and this is because activated carbon has due to the stronger adsorptivity; But activated carbon is physical absorption, and being does not have to select, and polarity and nonpolar molecule are treated alike, and has less molecule nitrile, acetone etc. are reached carbon monoxide, the more weak shortcoming of carbon dioxide adsorptivity.
Being used to make filter-tip material now mainly is acetate fiber, and the import of still needing at present of this acetate fiber needs foreign exchange and costs an arm and a leg more than at least two ten thousand yuan one ton, and the product cost of making is respectively at 25,000 yuan one ton.Understand the station-service polypropylene that has now according to us and manufacture filter tip, the price of this material is more cheap than acetate fiber, 15,000 yuan one ton.But form launch seldom, main cause is that polypropylene elasticity is big, and otch is rough, and the wire drawing phenomenon is arranged, and yield rate is low.BJ Tobacco Factory makes nonwoven to polypropylene earlier, boundling moulding then, and this cigarette holder also can only be used for low-grade cigarette.Also have a spot of cigarette to use active carbon filtration on the market now, the import of still needing of this filter tip, price about 30,000 yuan a ton.
The present invention adopts native cellulose to add the sepiolite replacement or part replaces synthetic fibers, makes soft, the whippy filter tip of porous, and technology is simply with low cost.Wherein native cellulose (as paper pulp etc.) greatly about 2,000 to 3,000 yuan per ton, sepiolite is at 500 to 5,000 yuan (deciding with grade) per ton, the cost of its finished product is at 6,000 to 8,000 yuan one ton, estimation can reduce product cost 1/4th to 1/2nd.
Purpose of the present invention mainly contains 2 points: the first, reduce coal tar in smoke and other content of harmful gas; The second, the manufacturing cost of reduction cigarette filter.
The present invention adopts the way of compound proportioning, can adjust the proportional quantity of fiber, sepiolite and other sorbing materials such as activated carbon, silica gel etc. according to the good and bad grade of tobacco, flue gas acid-base value etc., and make the pH value of flue gas moderate, thereby reduce coal tar in smoke and pernicious gas content greatly, improve smoke perfume, available tobacco inferior is obtained high-quality flue gas, enlarges the tobacco scope of application, obtains better economy and social benefit.
The present invention at first carries out the fine finishining activation processing to sepiolite, and natural sepiolite generally has two kinds of origin causes of formation, and a kind of is appositional pattern, and another kind is a hot-liquid type.The sepiolite impurity of appositional pattern is more, and purity is not high, and purification ratio is difficulty.The sepiolite impurity of hot-liquid type is few, the purity height.No matter the sepiolite of the sort of origin cause of formation is as long as purity just can be used for making filter tip more than 90%.The first step is pulverized sepiolite, grind into powder; Second step was with last about three days of 5% salt acid soak sepiolite powder; The 3rd step washed the sepiolite powder that soaked, and made pH value become neutral; The 4th goes on foot washed sepiolite powder dewatered drying, and till heating sepiolite powder no longer changes to weight under 150 ℃ to the 200 ℃ conditions.
1. spraying process:
Do base (as relatively thinner paper) with native cellulose, at first paper is drenched or gluing, last sepiolite powder of an amount of spraying or sepiolite add the powder of activated carbon, silica gel, dry and be pressed into the minitype corrugation paper of concavo-convex flute profile, be rolled into column and get final product, with staple fibre (as acetate fiber, polypropylene) then at spray glue before their boundling moulding or do not spray glue and spray the powder compacting that sepiolite powder or sepiolite add a small amount of other sorbing materials again and get final product.
2. mixing method:
The paper pulp made from native cellulose (as cotton paper slurry, wood pulp), add the sepiolite powder of activated processing or the sepiolite of certain proportioning and add the activated carbon powder, make both mix making beating by a certain percentage, the ratio of sepiolite and paper pulp is about 6: 4, through copying paper after eight or nine hours the making beating, quantitatively scope is every square metre of 25-30 gram, make paper after, be pressed into the minitype corrugation paper of concavo-convex flute profile, be rolled into the column moulding.
With spraying process and mixing method, wherein be that major ingredient adds a small amount of other material again and can form following product with the sepiolite:
1. sepiolite adds native cellulose.
2. sepiolite adds native cellulose and adds activated carbon
3. sepiolite adds native cellulose and adds staple fibre
4. sepiolite adds native cellulose and adds staple fibre and add activated carbon
5. sepiolite adds native cellulose and adds staple fibre and add activated carbon and add silica gel
6. sepiolite adds staple fibre
7. sepiolite adds staple fibre and adds activated carbon
8. sepiolite adds staple fibre and adds activated carbon and add silica gel
Utilize present technique, can reduce the harmful substance in the tobacco greatly, also reduced the manufacturing cost of cigarette simultaneously, and have enforcement simply, advantages such as remarkable in economical benefits.
