Description
Technical field
The present invention relates to filtering material, be specifically related to the preparation method and the cigarette mouth filter material of cigarette mouth filter material.
Background technology
Along with demands of social development, the security of cigarette product more and more is subjected to the attention of consumer and cigarette enterprise.One of important indicator that influences the cigarette security is a tar content, and in order to guarantee the security of cigarette product, State Tobacco Monopoly Bureau has assigned the timetable of rigid reduction tar for each cigarette enterprise.But because tar is closely related with cigarette odor-absorbing, therefore, the technology of stablizing cigarette odor-absorbing when exploitation reduces tar content becomes one of primary study direction of tobacco relevant enterprise unit.
Cigarette filter is one of effective means that reduces cigarette harm, and pipe tobacco and cigarette paper produce flue gas by burning, and flue gas forms the flue gas that the consumer sucked after filtering by cigarette filter.In order to improve cigarette filter focusing oil filtration effect, in the prior art, the improvement technology of cigarette filter is divided into substantially: filter structure improves, filtering material improves.Wherein, excellent filter tip, spices line mouth, absorption line mouth in the improved object lesson of filter structure such as binary composite filter tip, hollow filter tip, the rod, also the someone adopts resistance to suction that increases filter tip or the mode that increases the ventilation rate of filter tip to come filter structures is improved.Though can reduce tar by improving filter-tip structure, reduce harm, to cigarette to suck the influence of taste style bigger, so above-mentioned technology has certain limitation.
At present, an important directions of improved filtering material is to add filtering particle in filter tip, reaches the purpose that reduces tar content by this filtering particle.Disclosed filtering particle generally is divided three classes in the prior art: mineral material particle, compound synthetic particle, plant material particle.
Though mineral material particle has filter effect preferably, but in sucking process, has bad breath, the taste of the aesthetic quality of cigarette promptly being sucked flue gas has negative effect, and it is higher to be added with filter tip hardness when cutting of mineral material particle, influences the service life of cutter.For example, mention the graininess loess plasticity particle that will be adsorbed with tobacco aromatics using in the Chinese patent literature 0311218.1 and add in the cigarette filter, because of loess fine grained composition is a porous structure, surface area is big, adsorptivity and reactive strong can effectively be removed harmful components such as tar, nicotine.But, loess itself intrinsic bilgy odour be that tobacco aromatics using can't be covered, in the smoking property of cigarette process, can produce new assorted gas, influence the taste of sucking of cigarette.
Compound synthetic particle is meant the filtering particle that is composited by two or more material.For example, someone adds porous-starch and the compound filtering particle of making of silicates material (as sepiolite, bentonite, medical stone, zeolite or other synthesis of molecular sieve material) in the cigarette filter to, though compound synthetic particle has good filter effect to the tar in the cigarette and other harmful components, but the adding technology complexity of compound synthetic particle, and there is the shortcoming of introducing other assorted gas.
Compare with compound synthetic particle with mineral material particle, plant material particle excellent adsorption, add cigarette filter to after, the filter tip processability is good.Plant commonly used is an offal, and offal is meant the general designation of the master pulse and the offshoot of tobacco leaf central authorities, and its effect is to provide support, supply nutrient for tobacco leaf.Have good filling effect through the offal of expansion process, mix with tobacco leaf and fit over when making cigarette, not only can reduce exhaust gas volumn, and can reduce the consumption of pipe tobacco.In the prior art, the technical scheme of use offal as filter-tip packing material disclosed.For example, Chinese patent literature 200710066121.6 discloses a kind of with the technology that joins after the granulation of microwave expansion offal in the cigarette filter tip, but the cabo particle of this technology preparation still contains the material of a large amount of pure dissolubilities, so flue gas can not pass, and can only detour.In fact the cabo particle of this technology preparation has only simple interception function for flue gas, and it is very limited to reduce tar content.And, had specific smoke smell through the offal after the microwave treatment, be difficult to be applicable to the cigarette of different brands.
