Description
Technical field
The invention belongs to cigarette filter technical field, more particularly to a kind of composite cigarette filter and preparation method thereof and
A kind of cigarette.
Background technology
Cigarette industry has the history of more than 500 years, and tobacco has been inhaled since the 1950s be subject to sternness increasingly
Cigarette and healthy pressure from public opinion.It there are about 4,000 kinds of compounds in cigarette smoke, existing a large amount of components are accredited harmful so far, wherein causing
Cancer thing is up to kind more than 40.Wherein, cigarette smoke main component includes tar, nicotine (nicotine) and carbon monoxide (CO), tar
In condensed-nuclei aromatics, benzoin, phenols promote thing for carcinogenic substance and cancer, CO can make one anoxic, and nicotine not only easily makes one habituation,
The respiratory center of people can also be benumbed, causes the angiocardiopathy of people.
National governments and the World Health Organization advocate people's non-smoking, and take a series of smoking-control.It is however, existing
Still there is the smoker of substantial amounts in the world.Worldwide can not be comprehensively in the case of smoking ban, urgent need can be reduced effectively
The means of poisonous and harmful element in cigarette endanger people to reduce cigarette.
Mode the most effective is that exploitation is higher to cigarette smoke poisonous and harmful substance adsorbing and removing efficiency now
Filter tip.Cigarette filter is that filtering material roll web is wrapped up and forms filter tip part, and it is wrapped up with forming paper
And formed.At present, the filter material of cigarette used both at home and abroad is mainly acetate fiber, polypropylene fibre, activated carbon fibre.
The prior art proposes, using the path changed when main flume passes through filter tip, to extend filter tip to main flume
The mode of adsorption time improves method of the filter tip to the filter effect of flue gas.For example, Chinese patent CN201120161356 will
Cylindrical filter is divided into more piece mouth rod, and it is ventilative more to add one or more layers height among the acetate silk of every section mouth rod
The filter paper of stomata shape, increases flow distance of the flue gas in filter tip with this, but preparation method is complicated.In order to further
Reduce tar content in main flume, it will usually adding with suction-operated is added with graininess discrete form in fibre bundle
Add agent.But if additive additive amount is more, pressure drop, the increase Cigarette Draw Resistance of filter stick can be increased；If additive amount is few, institute
Adsorbable tar content is limited, still undesirable to the filter effect of flue gas, and filter efficiency is low.
The content of the invention
In view of this, it is an object of the invention to provide a kind of composite cigarette filter and preparation method thereof and a kind of volume
Cigarette, composite cigarette filter provided by the invention improve filter efficiency on the premise of pressure drop is not improved.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：
A kind of composite cigarette filter, including the fibre bundle filter stick of end docking and inorganic filter stick and it is coated on the fibre
Tie up the filter tip forming paper of beam filter stick and inorganic filter stick outer surface；
The inorganic filter stick is bonded through organic bond by inorganic adsorbent particle and formed.
Preferably, the particle diameter of the inorganic adsorbent particle is 0.75~1.5mm.
Preferably, the inorganic adsorbent particle includes inorganic porous material and inorganic binder；The inorganic porous material
Mass ratio with inorganic adhesive is 1：(0.25~4).
