Description
Technical field
The present invention relates to a kind of preparation having very much filter screen, it is related specifically to the preparation technology of melt-blown polyphenylene sulfide fibre stratum reticulare
And technology.
Background technology
Net containing fiber particularly meltblown fibers is widely used in the fixing granule of filtration and oils and fatss and heat-insulated, sound insulation
Etc. aspect application.
Wherein, in the application of above-mentioned filtering solid particles and contain the cleaner unit for filtering granule or mask
Deng.
And when this net produces, need the net of multilamellar is fixed together.
And the performance of filter bag used by sack cleaner is to affect one of principal element of its filter effect, with polyphenylene sulfide
(pps) filtrate being obtained for raw material has excellent thermostability, corrosion resistance and anti-flammability, is suitable in higher temperature and severe
Under the conditions of use, be mainly used in the dust removal and filtration of the high-temperature flue gas in the fields such as coal-burning power plant and boiler.
In existing invention, China Patent No. cn103961939a, publication date August in 2014 6 days, patent of invention is entitled
" a kind of preparation method of polyphenylene sulfide composite filtering material ", this patent is by melt-blown polyphenylene sulfide superfine fiber net and the short fibre of polyphenylene sulfide
Both are combined by array imbedding method, obtain polyphenylene sulfide composite filtering material, finally composite filtering material are carried out again by dimension net
Thermal finalization and surface calendering are processed.The filtrate of the method preparation comprises at least one of which melt-blown micro fibre layer so as to maintain good
Good air penetrability, significantly improves to the filter efficiency including pm2.5 finely ground particles.But, due to melt-blown micro fibre intensity
Not high, it is easily broken off in imbedding method recombination process, cause meltblown layer and base cloth layer bond strength relatively low, the filtrate of preparation is being grown
During time uses, easy prospects abrasion comes off melt-blown micro fibre layer with base cloth layer.
Chinese patent (patent No. cn102160944a and cn204246952u) describes one kind and adopts superfine fibre conduct
Surface layer, then carry out compound filtrate with base cloth layer, bottom, but how to solve the problems, such as that surface layer is be combined with each other with base cloth layer, bottom
Not corresponding Technology explanation.
Chinese patent 200780031924.6, publication date August in 2009 19 days, entitled " the thermostability nonwoven of patent of invention
Cloth ", which discloses a kind of polyphenylene sulfide heat-resistant nonwovens, is the multilamellar spun-bonded non-woven fabrics made by heat bonding, this
Bright multi-layer nonwoven fabrics filtering accuracy is higher, but, this patent of invention has high demands to thermal bonding technology, due to thicker fibrous layer
