It is existing as filtering material in the prior art for polyphenylene sulfide (PPS), but be mostly using molten
Melt spinning and prepare non-woven fabrics later, this method is complicated, the present invention is directed to prepare a kind of non-woven fabrics of melt-blown polyphenylene sulfide, prepares work
Skill is simple, and is made as the filtering material of cigarette, using the special molecular structure of polyphenylene sulfide, reaches excellent to tar
Adsorption effect.
Invention content
In view of the above problems, present invention aims at propose a kind of melt-blown polyphenylene sulfide for reducing tar content
Nonwoven cloth filter material and preparation method thereof, this method mainly prepare polyphenylene sulfide non-woven fabrics by meltblown, specifically include
Following steps：
A. the drying of polyphenylene sulfide
B. polyphenylene sulfide meltblown spinning
Polyphenylene sulfide after drying is subjected to melt-spraying spinning by screw extruder and melt-blowing equipment, feed zone melts
Tabetisol, compressional zone and drawing-off hot blast temperature graded.
C. the collection of polyphenylene sulfide non-woven fabrics
D. rolling and molding.
The concrete operations of the step a be by a certain amount of polyphenylene sulfide under conditions of temperature is 40~100 DEG C
Dry 12~36h, makes its water content be less than 0.2%.
The design parameter of the step b is：Screw extruder draw ratio is 25~50:1,140~190 DEG C of feed zone melts
290-310 DEG C of tabetisol, 320~340 DEG C of compressional zone；200~280 DEG C of drawing-off hot blast temperature；Screw speed is 10~70r/min；
Wind pressure is 0.15~0.4MPa；
Further the design parameter of preferred steps b is：Screw extruder draw ratio is 25~35:1, feed zone 180~
190 DEG C, 300~310 DEG C of melting zone, 320~330 DEG C of compressional zone；250~270 DEG C of drawing-off hot blast temperature；Screw speed is 30-
50r/min；Wind pressure is 0.15~0.4MPa；
When meltblown prepares PPS non-woven fabrics, the control of temperature influences big, temperature to the performance for being meltblown polyphenylene sulfide non-woven fabrics
The raising of the gradient distribution of degree can ensure that PPS uniformly melts, and improve PPS flow stabilities to greatest extent so that prepare
The diameter of the non-woven fabrics gone out is small, and thickness is evenly distributed, and has larger specific surface area, filter efficiency high.
The present invention controls 0.15~0.4MPa of wind pressure, under conditions of the wind pressure, fiber can obtain adequately by experiment
Drawing-off, obtained fibre diameter is small, is conducive to the filter effect for improving filtering material.
The concrete operations of the step c are that the polyphenylene sulfide fibre sprayed through spinneret is collected through autoadhesion, winding, are obtained
Polyphenylene sulfide non-woven fabrics.Wherein, lace curtaining is 40~120cm at a distance from spinneret, and lace curtaining output frequency is 5~10r/min.
After polyphenylene sulfide is prepared in melt-blown, need to carry out rolling and molding to it, rolling and molding largely affects
The filter effect of polyphenylene sulfide non-woven fabrics.
High molecular material generally existing is heat-shrinked, because under heat condition, there are internal stress for PPS fibers, higher than PPS glass
In the environment of glass transition temperature, fiber molecule chain relaxation, to make non-woven fabrics shrink.On the other hand, since melt-blown is made
The crystallinity of standby PPS non-woven fabrics is relatively low, PPS can be made to crystallize under hot environment, and temperature is higher, crystalline rate
Faster, crystallinity is higher, and strand arranges more closely, so that the percent thermal shrinkage of non-woven fabrics increases, heat-shrinkable is very
The filter effect of filtering material is affected in big degree.
Hot rolling technology is the key means for preparing polyphenylene sulfide fibre filtering material, and present invention finds be in hot-rolled temperature
85-95℃；Hot rolling pressure is more than 10MPa-25MPa, and when the hot rolling time is 2-5 seconds, using the short time, high temperature hot pressing ensured
The necessary hole of filter material material and good thermal contraction performance so that for reducing the melt-blown polyphenylene sulfide non-woven fabrics mistake of tar content
Filter material material has preferable filter effect.If hot rolling overlong time, the contraction that polyphenylene sulfide fibre can be caused violent destroys melt-blown
Three-dimensional structure in spun non-woven cloth reduces filter effect.
The polyphenylene sulfide meltblown spinning processing temperature is 140~340 DEG C, molecular weight 10-15w, preferably 12-15w.
The selection of polyphenylene sulfide raw material is the key that prepare melt spraying non-woven fabrics, when the molecular weight of polyphenylene sulfide is small,
Mobility is strong after polyphenylene sulfide melting, cannot function as the spinning solution of melt-spraying spinning, the spinning solution being meltblown out is difficult into fibre, Wu Fazheng
Fiber often is prepared, i.e., enabled to obtain a few fibres, the poor mechanical property of the fiber can not be applied in production and use.When
The molecular weight of polyphenylene sulfide is excessively high, and numerical value fusing point is higher, and its mobility is too low, and non-woven fabrics is prepared as spinning solution melt-blown
When, as-spun fibre difficulty or ease drawing-off, therefore fibre diameter is larger, the filter effect for the non-woven fabrics being prepared out is bad, the present invention
By repeatedly attempting, it is found that molecular weight is most suitable for spinning between the viscosity of the polyphenylene sulfide of 9-12w, and the fiber prepared is straight
Diameter is small, and porosity is high.
The invention also discloses a kind of melt-blown polyphenylene sulfide nonwoven cloth filter material for reducing tar content, the filter core materials
Material for melt-blown polyphenylene sulfide non-woven fabrics, be meltblown polyphenylene sulfide non-woven fabrics in fibre diameter be 1-20 μm, preferably 1-10 μm, more preferably
1-5μm。
The repeat unit structure of wherein polyphenylene sulfide is as follows：
As it can be seen that PPS is mainly linear structure, flatness is preferable, contains aryl and polar group on strand, and tar
Main component is the oxide of hydrocarbon and hydrocarbon, sulfide etc., and therefore, this programme will carry out tar using polyphenylene sulfide non-woven fabrics
Filter absorption, and it is found that polyphenylene sulfide non-woven fabrics has good adsorption effect to tar.
Conventional non-woven fabrics is the fiber lapping later by the way that polymer is first prepared into fiber, passes through self-adhesion, hot sticky, change
Learn bonding or the obtained non-woven fabrics of method that tool is reinforced, this conventional non-woven fabrics because its raw material selection and it is subsequent plus
The diameter of work, fiber is generally large, often tens microns or even hundreds of microns.The present invention is prepared using meltblown
Fibre diameter is small, usually 1-20 microns, and the fiber of the polyphenylene sulfide of minor diameter has large specific surface area, while preparing
The aperture of non-woven fabrics is smaller so that non-woven fabrics has preferable mechanical property and strainability.
What a kind of melt-blown polyphenylene sulfide nonwoven cloth filter material for reducing tar content disclosed by the invention was prepared
