The preparation method of the high activity composite filtering material of described a kind of sewage disposal fusion-jetting polypropylene blending tourmaline, comprises following steps:

(1) first tourmaline powder, polyethylene glycol are dropped in the water of 20-25 weight portion, be stirred to after material dissolves dispersion completely, drop into charing oleagenous plant shell micro mist, soak 2-2.5h, obtain material A for subsequent use, again lauryl sodium sulfate is dissolved in subsequently in remaining water, and add molecular sieve of Nano zeolite, high-speed stirred makes uniform and stable dispersion liquid, and then add material A, continue to be uniformly mixed 50-60min, finally by gained mixed material heated-air drying, remove moisture completely, be broken into 300-400 order micro mist for subsequent use;

(2) polypropylene is mixed with oyster shell whiting, polyether modified silicon oil, stir in rear input double screw extruder and melt extrude granulation at 180-190 DEG C of temperature, obtain modified polypropylene agglomerate;

(3) step (1) gained material is mixed with modified polypropylene agglomerate and other leftover materials, drop in melt-blown non-woven former after stirring, melt is the meltblown beam spinneret orifice ejection of 200-220 DEG C through temperature, wherein orifice diameter is 50-100 μm, ejection filament stretch under the high velocity, hot air stream effect of 230-250 DEG C laggard enter receiving system, filament to be composite assembles shaping on the reception device, completely cooling after and get final product.

Beneficial effect of the present invention:

The present invention utilizes the Aqueous Solutions of Polyethylene Glycol after tourmaline activation process to carry out immersion modification to charing oleagenous plant shell micro mist, improve the adsorption reactivity of powder, and mix molecular sieve of Nano zeolite wherein, widen the retaining power of filtrate further, the fiber filaments that this species complex filtrate micro mist is carried on the melt-blown preparation of modified polypropylene agglomerate is collected to obtain after being shaped having complicated, the material of multichannel dimensional network structure, the material mechanical performance of this structure improves, more firm, not cracky, the efficiency of adsorption fouling thing is higher, in addition its form is flexible, according to environment for use and the product preparing variform and size can be required, can reuse.
