Background technique
Polybutylene terephthalate (PBT) is a kind of crystalline thermoplastic polyester, its fast, mechanical strength with crystallization rate The features such as height, dimensionally stable, good electrical insulation capability, additionally has heat-resisting, acidproof, resistance to greasy dirt outstanding and resistant to chemical etching Performance.The non-woven fabrics fiber of meltblown preparation is thin and soft, is a kind of ideal filtering material.The present invention is directed to by suitable stream Dynamic modifying agent, which is added in slice, carries out blending and modifying, and fluidity of molten in melt-blown processing is substantially improved；And prepare a kind of aperture Smaller, the higher modified melt spraying non-woven fabrics filter core of filtering accuracy, to there is good application prospect in terms of dust-removal cloth-bag.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of modified nothing of dust-removal cloth-bag ferric trichloride-electret is provided The preparation method of woven fabric, the dust-removal cloth-bag modification nonwoven cloth made according to this method are excellent to the strainability of air.
The present invention is achieved by the following technical solutions:
A kind of dust-removal cloth-bag ferric trichloride-electret modification nonwoven cloth preparation method, which comprises the steps of:
(1) blending and modifying of polybutylene terephthalate (PBT) slice:
By 94-96 parts of dry polybutylene terephthalate (PBT) slices and 4-6 parts of flow ability modifying agents in double screw extruder It is blended, after melt stream condensation, is air-dried through air-dry machine, pelleter pelletizing, obtain modified polybutylene terephthalate (PBT) slice； Modified slice is squeezed out after heating melting through spinning nozzle in screw extruder, melt stream is drawn into fiber, cooling Solidification, autoadhesion act on forming non-woven fabrics；
(2) preparation of ferric trichloride modified non-woven fabrics:
Gained non-woven fabrics in (1) is immersed in the corrosive liquid that ferric trichloride and aqueous sulfuric acid are formed, is reacted at 30-40 DEG C After 3-5h, in 60-80 DEG C of dry 1-2h, 5-10h is impregnated in water at room temperature, then at 60-80 DEG C of dry 1-2h, tri-chlorination is made Iron modification nonwoven cloth；
(3) method of electret modification nonwoven cloth:
The ferric trichloride modified non-woven fabrics of gained in (2) is cut, is then placed under Xelminator and slowly moves, remove table Face electrostatic after being heated at 105-115 DEG C, carries out corona charging with electret equipment, and dust-removal cloth-bag is made and is modified Non-woven fabrics.
Further, the drying that polybutylene terephthalate (PBT) is sliced in step (1): by polybutylene terephthalate Ester slice dry 4-6h in 104-106 DEG C of vacuum drying oven, for use；
Flow ability modifying agent is flow ability modifying agent FM, and melt-spraying spinning temperature is 225-390 DEG C.
Further, the electret charging time is 20-30s, charging distance 1-5min, charging voltage 10- in step (3) 15kV。
The present invention has the advantage that compared with prior art
(1) it is blended to be granulated using twin-screw and is prepared for the modified slice of polybutylene terephthalate (PBT)-flow ability modifying agent, mixture In system, a small amount of flow ability modifying agent can be used as crystallization nucleating agent and promote crystallization, and flow ability modifying agent is to polybutylene terephthalate The improvement effect of the mobility of ester is obvious；The fibre diameter of modified melt-blown sample and aperture are smaller, and pore-size distribution is also relatively equal It is even, and the breaking strength of non-woven fabrics is not reduced.
(2) using ferric trichloride come modification nonwoven cloth, fiber surface feature changes, and non-woven fabrics fiber surface occurs Phenomenon of rupture, hydrophilic angle also decrease；Air-treatment effect is more satisfactory, can meet standard.
(3) electret processing can be good at solving the contradiction between filtration resistance and filter efficiency, so that filtering material has There are a high efficiency, the more brilliant filter capacity of lower resistance, treated that charged meltblown web can effectively filter sky for electret Submicron Particles in gas；The surface potential of nonwoven cloth filter material is higher after electret processing, then its filter effect promotion is got over Greatly；
Non-woven fabrics is made dust removal and filtration cloth bag, surface all by singing, the process such as press polish, prevent two caused by fibre shedding Secondary pollution；High temperature resistant index, filtering accuracy, Air permenbility are attained by standard.
