Description
Technical field
The present invention relates to a kind of novel antistatic filtering material and preparation method thereof, belong to fabrics for industrial use field.
Background technology
In filtering material use procedure, a large amount of dusts of discharging impact the dust-collecting face of filtering material and produce friction, because they are different to the attraction of electronics, make to there occurs electro transfer between object, raw material fiber due to filtering material is all the good insulator of insulating properties, therefore the electric charge produced cannot leak thus rests on the dust-collecting face of filtering material and form electrostatic in inactive state.Although electrostatic electricity is little, easily there is discharge spark because its voltage is very high, when the concentration of mist, dust in filter bag is comparatively large, when discharge spark energy is also large, just may be set off an explosion or fire by electrostatic spark.
General filtering material does not possess anti-static function, so anlistatig most effectual way is exactly by all means by derivation that electrostatic charge is very fast.The antistatic processing method that current filtering material is conventional has following several:
Adding conductive filament when preparing non-woven filter material at a certain distance at Ji Bunei, as in publication CN102337622.A, adding the carbon black at 26-1500 dawn at interval of 2.7-3.5cm or electrostatic eliminated by graphite fibre by filtrate base cloth is radial.
In raw material, a certain amount of conductive fiber or stainless steel fibre is mixed into, as in publication CN94225873.8, by being mixed into NACF in raw material or metallic conduction silk fiber eliminates electrostatic when preparing non-woven filter material.
Antistatic treatment is carried out at filtering material dust-collecting face layer overlay conducting fibrous web or employing surfactant, as in publication CN102995294.A, the ultra fine conductive fibers net obtained by electrostatic spinning spinning head being extruded stretching is superimposed upon fibre web surface and acupuncture obtains antistatic filtering material; In publication in CN103276532.A, by a kind of glue being furnished with nanoscale graphite powder of filtrate element felt dipping is prepared into antistatic filtering material.
Although it is simple to add conductive filament processing technology at Ji Bunei, because filtering material surface fiber is the good insulator of insulating properties and conductive filament is only mixed between weft yams, thus cause the antistatic property impact of conductive base cloth on filtering material less; Although add conductive fiber or stainless steel fibre can make filtering material possess good antistatic property in raw material, but holding difference when conductive fiber or stainless steel fibre and general fibre blending and acupuncture time easily damage is caused to pricker because performance is more crisp, add technology difficulty and processing cost; Although it is superior that filtering material dust-collecting face layer overlay conducting fibrous web or employing surfactant carry out antistatic treatment antistatic property, but after permanent dust impacts, surface layer ultra fine conducting fibrous web easily comes off, antistatic surface agent conductive effect also can sharply reduce thereupon, and the life-span of antistatic filtering material also reduces thereupon.
