Description
Technical field
The invention belongs to environmental protection technical field, is related to a kind of novel oil absorption cotton, more particularly to a kind of oil suction efficiency is not
The novel oil absorption cotton that can be obviously reduced with the increase of the reuse number of oil absorbent material.
Background technology
With the continuous development of world industry, greasy dirt discharge increasingly increases, and the approach and chance of oil leak are also increasingly
It is more, extensive Leakage Energy accident particularly caused by maritime shipping.Marine oil pollution ecological ring of the serious threat to coastal waters
Border, the oily pollution for administering near sea water environment have been very urgent.It is main but sea pollution by oil is administered and also lacks effective method
To rely on and reduce opportunities for contamination, the oily waste water of pollution sources is pre-processed, control greasy dirt arranges extra large total amount etc..Oil absorption material is just
It is the great attention for causing wide people in this case.
Common oil absorption material has asphalt felt and oil absorbent material in the market, and oil absorbent material is one kind by inertia polypropylene melt-blown
It is made, adsorptive liquid and it can be effectively kept here after manufactured fiber and non-woven fabrics are specially treated.Adsorption production is all bag
It is rolled in in polypropylene fibre or non-woven fabrics of the sewer through surface activation process agent processing, outer cloth and its tough and tensile durable,
The extremely strong adsorptivity brought with powerful capillary attraction power, oil absorbent material is flowed to so as to absorb leakage liquid, effectively prevented
The diffusion of leakage, product is reusable after twisting, extruding, can reclaim 72%-90% leakage fluid.This material it is excellent
Point is also fire-retardant, does not produce dust, without storage limitation time etc..
But existing oil absorbent material still has the problem of oil suction multiplying power is low, oil suction efficiency is low, and with oil absorbent material
Repeatedly use, its oil suction efficiency also can be reduced gradually therewith.
The content of the invention
For the above mentioned problem of prior art, can be reused it is an object of the present invention to provide one kind and oil suction
What efficiency will not be reduced substantially, there is the novel oil absorption cotton of superelevation oil suction multiplying power and superelevation oil suction efficiency.
In order to solve the above-mentioned technical problem, technical scheme is as follows：
A kind of novel oil absorption cotton, including be stacked porous cotton layer, filter layer and there is the bone porous graphite of 3D
Alkene aerogel layer, the graphene aerogel layer is adulterates the graphene aerogel of nitrogen, and the doping mass percent of nitrogen is
50%~80%,
The porous cotton layer includes the first cotton layer and the second cotton layer, and the filter layer includes the first filter layer and the
Two filter layers, first filter layer and the second filter layer are separately positioned on two relative side of the graphene aerogel layer
On, first cotton layer is arranged on side of first filter layer away from the graphene aerogel layer, and described second
Cotton layer is arranged on side of second filter layer away from the graphene aerogel layer.
The porous cotton layer is with super-hydrophobic/super-oleophilic polypropylene material.
Further, the thickness of first cotton layer and the second cotton layer is 1~3mm.
Further, the porosity of first filter layer and the second filter layer be 60%~80%, pore size be 1~
10μm。
Further, nitrogen source is isopropylamine or tripropyl amine (TPA) used by the graphene aerogel of the doping nitrogen.
Further, the graphene aerogel of the doping nitrogen using by the way of being chemically crosslinked by N doping to graphene gas
In gel.
Further, the porous cotton layer also includes fire retardant, and the fire retardant is diphenylphosphate.
Further, the filter layer is activated carbon filter layer.
A kind of novel oil absorption cotton of the present invention, has the advantages that：
(1) novel oil absorption cotton of the invention includes being cascading porous cotton layer, filter layer and porous with 3D
The graphene aerogel layer of skeleton, wherein, there is graphene airsetting of the bone porous graphene aerogel layers of 3D for doping nitrogen
Glue, and the doping mass percent of nitrogen is 50%~80%, is greatly added by the doping of nitrogen in graphene aerogel
Hole and its conservation rate to oil content.
(2) the porous cotton layer that outermost layer of the invention is set be with super-hydrophobic/super-oleophilic polypropylene material, because
This, quickly can mutually melt with oil reservoir, be advantageous to accelerate swelling rate, effectively avoid the expansion of oil leak area.
(3) present invention is provided with filtering between porous cotton layer and with the bone porous graphene aerogel layers of 3D
Layer, the filter layer can intercept most of particulate matter in outside oil content, enter 3D so as to avoid particulate matter well
Bone porous graphene aerogel layer, and then the hole in aerogel layer is blocked, be advantageous to improve the absorption times of aerogel layer
Rate and absorption efficiency.
Further, since when oil content is extruded away from oil absorbent material, the particulate matter in oil content can often remain in aeroge
In the hole of layer, for the present invention by setting filter layer to be intercepted particulate matter, prevention particulate matter enters graphene aerogel layer,
So as to extend the use birthday noodle of oil absorbent material, and oil absorbent material is can guarantee that after repeatedly using, graphene aerogel layer
Hole will not block, and ensure that absorption efficiency.
