Description
Technical field
The present invention relates to cigarette cigarette filter tip material field and non-woven field, more particularly to a kind of electret superfine fibre is fragrant
Cigarette filter tip material and preparation method thereof.
Background technology
Include particulate, normally referred to as tar in cigarette smoke.Contain substantial amounts of chemical composition in tar, there are 4000 to arrive
5000 kinds, be all the unburnt product of tobacco.Cigaratte filter is in order to the tar in filter tobacco etc. is harmful
Material.Existing frequently-used cigarette filter tip material is acetate fiber cigaratte filter, and acetate fiber is obtained using wet spinning, production
Technological process is long, and the solvent used in spinning process is harmful to environment, there is three-waste pollution.Additionally, cellulose acetate fibre is in filter
The effect of the harmful carcinogen (such as polycyclic aromatic hydrocarbon and aldehyde material) in except cigarette main flume is not very good, removal
Only 40% or so of polycyclic aromatic hydrocarbon material.
Cigarette filter can filter smoke composition, to reduce the soakage of tar and nicotine.But cigarette cigarettes are filtered
After mouth, draw resistance is greatly increased, and noxious material is more.Such as carbon monoxide, BaP are all in smoking process, by cigarette
Careless contained organic substance imperfect combustion generation, resistance is bigger during smoking, and oxygen supply is more insufficient, burns more incomplete, has
The growing amount of noxious material is also more.Fiber is thinner, and strainability is better.Three kinds of major functions of cigarette cigaratte filter include direct
Intercept, inertia is compressed and precipitin, most common is directly to intercept cigaratte filter.Filtering is a process for complexity, also
It is after saying that tar droplet is separated from smog, to be just attached to above when they reach the surface of cigarette filter tip material.It is fine
Dimension is thinner, and the filter efficiency of cigarette cigaratte filter is higher, and the acetate fiber diameter used by convention filter is between 7~20 μm.
The content of the invention
In order to solve the problems, such as that cigarette filter material filter efficiency is not high in the prior art, the present invention provides a kind of electret and surpasses
Fine fibre cigarette filter tip material and preparation method thereof and preparation facilities.
A kind of electret superfine fibre cigarette filter tip material, is the melt-blown micro fibre of 1-5 μm of diameter.
Further, the melt-blown micro fibre is female by the thermoplastic of 94-99 weight portions and the electret of 1-6 weight portions
Grain is made.
Further, the melt-blown micro fibre have passed through electret treatment.
A kind of preparation method of electret superfine fibre cigarette filter tip material, specifically includes following steps：
Step S1, the electret master batch of the thermoplastic of 94-99 weight portions and 1-6 weight portions is uniformly mixed, mixed
Close material；
Step S2, device for melt blowing prepare melt-blown micro fibre using compound；
Step S3, cooling beaming device are cooled down and boundling to the melt-blown micro fibre that device for melt blowing sprays；
Step S4, collection device are processed and collected to melt-blown micro fibre, obtain electret superfine fibre cigaratte filter
Material.
Further, the cooling beaming device of the step S3 includes packaged air conditioner and curtain net reception device；The step S3
Specially：Packaged air conditioner is cooled down to melt-blown micro fibre, and the melt-blown micro fibre after cooling falls along device for melt blowing successively
In the curtain net reception device of the breadth direction transmission of middle meltblown beam, curtain net reception device is surpassed to melt-blown micro fibre boundling
Fine fibre beam.
Further, the cooling beaming device of the step S3 includes packaged air conditioner and the first beaming device；The step S3
Specially：The packaged air conditioner is cooled down to the melt-blown micro fibre of the ejection of device for melt blowing, and first beaming device is to cold
But the melt-blown micro fibre after carries out boundling；And first beaming device is not less than in device for melt blowing along the width in breadth direction
Meltblown beam along breadth direction width.
Further, the melt-blown micro fibre is processed by electret after cooling down beaming device cooling and boundling, also and filled
Putting carries out electret treatment.
Further, the electret voltage of the electret processing unit is 5-20kV, electret interval 20-60mm, electret time
5-10s。
Further, the thermoplastic of the step S1 is any one in PP, PET, PA, PLA or PE.
The beneficial effects of the invention are as follows：Fiber is thinner, and the filter efficiency of cigarette cigaratte filter is higher, used by convention filter
Acetate fiber diameter between 7~20 μm, conventional meltblown cannot be obtained fibre bundle, and fabric nonwoven cloth can only be obtained, this
Invention is improved conventional meltblown method, and the cooling of meltblown fibers is accelerated by increasing cold side blowing, makes fiber completely cold
But collected in the case of, it is to avoid the bonding between meltblown fibers, disorientation, melt-blown fibre occur at relatively high temperatures prevented also from fiber
Dimension remains certain degree of orientation, and fiber strength is improved.Meanwhile, by curtain net by tradition prepare non-woven fabrics perpendicular to web width
Direction movement is changed to be moved along web width direction, and diameter can be directly obtained can reach 1~5 μm of superfine fibre beam, and carefully
Degree even variation is small, thus filter effect is high, is avoided that the problem of environmental pollution in acetate fiber production.The present invention is to melt-blown super
Fine fibre carries out electret treatment, is processed by distinctive electret, melt-blown micro fibre can be made to polarize and take electric charge, so as to not
In the case of increasing material respiratory resistance, the Electrostatic Absorption performance of material is improved, while electric charge conservation rate was up to more than 2 years, can
It is particulate dust, filtration resistance low advantage high with filter efficiency by electrostatic effect paved set.
