The invention belongs to cigarette filter technical field, specifically disclose it is a kind of can auto-control ventilation rate cigarette filter, including filter stick, the cladding filter stick forming paper and be coated on the cork paper on forming paper surface；The cork paper is provided with plenum area, and the plenum area is provided with several ventilation holes；The phase-change material layers for closing the ventilation hole are provided between the plenum area and forming paper.The invention also discloses the preparation of the cigarette filter and applications.Cigarette filter of the present invention, auto-control is carried out with cigarette smoking progress to filter tip ventilation, it that is, in the initial suction stage filter ventilation rates of cigarette is zero, only 2~3 mouthfuls before suction terminates, it realizes filter tip ventilation, had both achieved the purpose that cigarette smoke lowering harm and decreasing coking, realization reduces flue-gas temperature and flue gas concentration in 2~3 mouthfuls of aspiration procedures, burning sensation is eliminated, realizes the consistency and stability of whole branch cigarette smoking style.
Description
Technical field
The invention belongs to cigarette filters to design manufacture field, and in particular to a kind of cigarette filter material.
Background technique
Cigarette filter has become the important medium of cigarettes reduce coke damage, and industry is inside and outside in cigarette filter material and configuration aspects
A large amount of fruitful research work are carried out.Cigarette filter mainly by aerosol particle through directly retention, inertial collision and
Diffusional deposition and realize to harmful substances in flue gas retention filtering, this not only with the physical property of filter tip and the close phase of structure
It closes, and closely related with cigarette filter Temperature Distribution.In 5~7 mouthfuls of aspiration procedures of cigarette, flue gas concentration and flue-gas temperature liter
Height, wherein the concentration of total material phase object and harmful substance is apparently higher than 1~4 mouthful of front, and filter tip flue-gas temperature highest in flue gas
Up to 70 DEG C~80 DEG C, the flue-gas temperature of filter end has been even up to 100 DEG C or more under depth suction mode, excessively high flue gas
Temperature and concentration not only influence filter tip to the rejection effect of harmful substances in flue gas, can also generate burning sensation, influence whole branch cigarette
The consistency and stability of style are aspirated, reduces consumer to the satisfaction of flue gas aesthetic quality.It can be seen that in cigarette filter
Flue-gas temperature retains efficiency and aesthetic quality to filter tip and can play a key effect.Using filter tip ventilation dilution lowering harm and decreasing coking,
Through being used widely in cigarette product.Filter tip is divulged information while diluting flue gas, can use environment normal temperature air and cigarette
Heat exchange of the gas in filter tip reduces filter tip temperature.However, flue gas composition is become in what is be incremented by by mouth during the smoking process
Gesture, in initial suction stage, it is too low and influence mouthfeel that filter tip ventilation dilution will lead to smoke perfume ingredient.
In the prior art, it is the temperature, the harmful components that reduce cigarette, is mostly to add types of functionality in cigarette pole to add
Add agent.For reducing last three mouthfuls of the temperature of cigarette, the method for prior art report mainly adds phase in cigarette pole
Become material；For example, the Chinese patent literature of Publication No. CN105996121A disclose one kind can be by phase transformation release function object
The filter stick additive of matter.The Chinese patent literature of Publication No. CN 104263321A discloses a kind of controllable cigarette filter cigarette
The composite phase-change material of temperature degree is born under Sodium Polyacrylate effect by cocrystallization by sal glauberi and sodium tetraborate decahydrate
It is loaded on expanded graphite and obtains.For another example the Chinese patent literature of Publication No. CN104449586A discloses a kind of controllable cigarette
The organic/inorganic composite phase-change material of filter tip flue-gas temperature.The prior art be usually by filter stick add phase-change material with
The purpose for realizing filter tip cooling, will affect the organoleptic quality of cigarette to a certain extent.In addition, if cigarette filter be always maintained at it is good
Good ventilation, such as just have biggish ventilation in suction early stage, it will largely influence to aspirate mouthfeel.
Summary of the invention
To overcome technical problem of the existing technology, the present invention provides it is a kind of can auto-control ventilation rate cigarette filter
Mouth, it is desirable to provide it is a kind of to use physical method, self-service it can regulate and control to aspirate last three mouthfuls of temperature and dilute the cigarette of harmful substance
Filter tip.
The second object of the present invention is to provide the preparation method of cigarette filter described in one kind.
It is a third object of the invention to provide the application of cigarette filter described in one kind.
4th purpose of the invention is, provides a kind of cigarette for being hinged with and having the cigarette filter.
