Description
Technical field
The present invention relates to oily waste treatment field, particularly relate to the efficient oil absorbent material of a kind of leakproof.
Background technology
Reveal when oil occurs on sea, or when factory's generation leakage of oil pollutes annex river course, generally have the method for three kinds of wipe oils; one is dispersion method; namely adopt oil dispersant, smash oil film, make it become particulate; be distributed in aqueous phase and go; oil dispersant accelerates the atomization process of oil, and oil is vertically spread, and does not form oil film in water surface; thus do not go to adhere to boats and ships, reef and coastline.Use dispersant to add the surface area of oil, accelerate the biodegradation of oil.But dispersant often toxicity is comparatively large, and when oil spill area is large, carburetion efficiency is not high, and is only applicable to the process of sea oil leakage.Two is freezing methods, namely adopts fuel thickener, improves oil viscosity rapidly, makes oil slick form block, is convenient to reclaim, and freezing method is general not as dispersion method, because complex manufacturing, cost is high, reclaims difficulty.Three is absorption methods, namely adopts oil absorption material to be adsorbed by oil, thus reaches the object of cleaning oil pollution.Absorption method is the basic method solving oil pollution, have the effect of process oil pollution preferably, and the greasy dirt of absorption also reclaims by processing.
The research of oil absorption material addresses this problem the best way, through the development of science and technology, no small achievement has been achieved on the one hand at this, the emphasis inorganic material of original research, natural organic due to oil absorption poor, water absorption is many and leave the visual field of people gradually, and the focus of research now often concentrates in the preparation of functional polymer.At present, all have the exploitation of synthesis oil-absorbing resin both at home and abroad, but emphasis is different, its synthesis material can be divided into esters of acrylic acid and a-olefines.Because the latter is expensive, therefore the esters of acrylic acid material that uses synthesizes more.
Although existing polymer oil absorption material is water suction and only optionally oil suction seldom, in use pressurized easy oil leakage, causes secondary pollution.And these oil absorption materials in absorption greasy dirt process significantly change indicate absorption greasy dirt number, thus can not judge whether oil absorption material adsorbs intuitively saturated, often do not accomplish the adsorption capacity utilizing oil absorption material to greatest extent in actual use, cause waste.In addition, there is serious defect in the oil absorption material of chemical synthesis or chemical modification: (1) material self is exactly the material of biological non-degradable (or biology can not be degradable), to remove while greasy dirt again contaminated environment once again; (2) product preparation process is complicated, cost intensive; (3) often have the residual of accessory substance in product, most of accessory substance is surfactant, and industrial waste water self endangers environment exactly.
Summary of the invention
Technical problem to be solved by this invention is that how overcoming existing oil suction product easily causes secondary pollution, complex manufacturing, cost intensive, easily causes the defects such as secondary pollution.
In order to solve the problems of the technologies described above, the invention provides the efficient oil absorbent material of a kind of leakproof, described oil absorbent material comprises PE application of anti-leakage layers and blotter coat, described PE application of anti-leakage layers is fixed along the edge compound of blotter coat, described blotter coat is formed at PE application of anti-leakage layers surface, the material of described blotter coat is macromolecular fibre, and described blotter coat surface and inside are spongy, and described oil absorbent material surface has bellmouth.
The thickness of described PE application of anti-leakage layers is 10 ~ 30mm, and the thickness of described blotter coat is 20 ~ 100mm.
Described bellmouth macropore diameter is 300 ~ 1000 μm, and described bellmouth small aperture is 10 ~ 500 μm.
Have loose structure in described blotter coat, described loose structure communicates with bellmouth, and the size in the hole of described loose structure is less than or equal to bellmouth small aperture.
Described oil absorbent material is prepared from conjunction with acupuncture production technology by horizontal disc rotating centrifugal spinning method.
The raw material of described macromolecular fibre is polypropylene, high density polyethylene (HDPE), low density polyethylene (LDPE), PET.
Described macromolecular fibre is the intact filiform of fibre structure, and described oil absorbent material is sheet, pillow or strip, and described oil absorbent material can oil suction repeatedly.
