Description
Technical field
The present invention relates to a kind of preparation methods of efficient absorption oil absorption material, belong to environment-friendly materials technical field.
Background technique
With the rapid development of science and technology, the discharge of a large amount of industrial wastewaters and oil carrier, oil tank leakage accident cause water
Body pollution, oil pollutant are to cause one of major pollutants of water pollution, constitute serious prestige to ecological environment
The side of body.Oil pollutant in common absorption method processing water body.Oil absorption material is as a kind of functionality for waste oil recycling, processing
Material is widely used in millwork leakage of oil, oil, food waste oil and sea and land crude oil leakage in plant chimney stalk
Processing.Common are type oil absorption material and inorganic type oil absorption material exist more adsorption efficiency is low, easily cause secondary pollution, at
The defects of this is high.How effectively to administer the petroleum and products thereof spilt into ocean or other water bodys is many countries and mechanism
Research emphasis, by prolonged effort, existing main oil spilling control measures include：Physical method（The oil fence, asphalt felt,
Oil skimmer etc.）, chemical method（Detergent, fuel thickener etc.）And biological method（Dispensing bites oily microorganism or nutritive salt etc. and promotes petroleum
Decomposition）, the often combined use of a variety of governing measures in an oil spill accident.Although having developed a variety of oil spilling improvement sides
Method, but there are still some at high cost, low efficiencys, oil spilling processing be not thorough the problems such as still allow of no optimist.Therefore, how to make
It is one of hot and difficult issue of current research that standby efficient out, cheap oil spilling, which administers material, with huge social benefit and
Economic benefit.Wherein, fuel thickener can float on the water surface and beat convenient for machinery by oil spilling rapid condensation at solid or semisolid bulk
Fishing, it has many advantages, such as effectively to inhibit, and the diffusion of oil, toxicity is low, condensation of oil is convenient for recycling；Oil absorbent can effectively adsorb oil spilling,
And oil cut rate can be effectively kept, convenient for salvaging, recycling.
Small molecule fuel thickener is a hot spot of current research, mainly utilizes the self assembly performance of small molecule, small molecule
Between can be self-assembly of in one-dimensional direction fibre by non-covalent interactions such as hydrogen bond, Van der Waals force, electrostatic attractions
Shape, band-like, tubulose or helical form nanostructure are tieed up, then intertwine with each other into three-dimensional network structure, utilizes surface on this basis
Oil spilling equal solvent molecule is retained or be fixed in network by tension, capillary force etc. forms gel.Physical gel is typically belonged to,
Different with chemical gel, physical gel can be realized the reversible phase transition of sol-gel under certain outside stimulus, such as hot
Time of small molecule fuel thickener and solidifying oil may be implemented using the phase transition of this sol-gel for processing, concussion, mechanical shearing etc.
It receives and recycles.And the small molecule structure unit in small molecule fuel thickener be mainly some abundances, have unique stereochemical structure and
The natural products molecule of more decorating sites, such as：Amino acid, carbohydrate, cholesterol, organic salt etc., this not only simplifies synthesis step,
Many advantages, such as more imparting gel rubber system environmental protection, economy, biocompatibility has huge researching value and application potential.
But the method that fuel thickener reported in the literature can effectively coagulate oil now usually mixes fuel thickener with oil product, using adding
Cosolvent is added in promotion gelling in heat of solution-room temperature cooling means in the mixture of fuel thickener and oil product, this is for reality
Border is using there are certain difficulties.A kind of important material is exactly using natural material as base in the developing direction of oil absorbent
Plinth, by simply handling the oil absorbent product of preparation environment-friendly type, in numerous processing methods, high temperature pyrolysis carbonization is a kind of ratio
More effective, simple method.Although oil absorbent can effectively adsorb oil spilling, factice cannot be coagulated.
In short, preparing Biocomposite material using waste spinning fiber, dirt of the traditional treatment method to environment not only can solve
Dye problem, and solve the problems, such as shortage of resources and waste to a certain extent, accomplish real environmentally friendly low-carbon, to have
Certain economic benefit and social benefit.Therefore, how to prepare efficient, cheap oil spilling and administer the heat that material is current research
One of point and difficult point, with huge Social benefit and economic benefit.
Summary of the invention
The technical problems to be solved by the invention：It is deposited for common are type oil absorption material and inorganic type oil absorption material more
Adsorption efficiency it is low, easily cause the problem of secondary pollution, propose a kind of preparation method of efficient absorption oil absorption material.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：

The present invention is compared with other methods, and advantageous effects are：
（1）Soybean protein itself contains part ester, these ester groups be it is oil-soluble, referred to as lipophilic group, their presence makes carboxylic
Methyl soybean protein has part lipophilic, so that grease system be made to be capable of forming WO emulsion；In soybean protein
It is added to ferric ion, so fuel thickener has more hydroxyls, is capable of forming more Hydrogenbonds, thus make to be formed
The structure of oleogel is more stable；And the water solubility of salt that ferric ion and carboxymethyl are formed is small, so product is in water
It is not easy to be dispersed by water, oleogel water imbibition is small, the water surface can be floated on, so solidifying oil better performances；
（2）There was only carbon carbon saturation segment and phenyl ring side group in the segment of polystyrene, nonpolarity or low pole is presented, has good
Hydrophobic-lipophilic, therefore, manufactured electrostatic spinning fiber have good hydrophobic-lipophilic；Simultaneously electrostatic spinning fiber have compared with
Small fibre diameter, lesser fiber membrane aperture, higher porosity and coarse micro-nano multilevel structure, and because it is multistage
The introducing of structure, the specific surface area and pore volume for increasing substantially fiber enhance oil product in the wettability of fiber surface, fiber
Small-bore can also enhance capillary pressure, improve to the adsorptivity of oil product and huge specific surface area also increase oil suction
Amount；
（3）The present invention improves the adsorptivity to oil spilling using electrostatic spinning fiber, then carries out foaming processing to electrostatic spinning fiber, so that
The density of entire material reduces, and after foaming is handled, the hole of entire material is more, can adsorb more oil spillings；
It recycles fuel thickener made of soyabean protein powder to carry out gel to the oil spilling of absorption, then floats on the water surface, facilitate recycling and again
It utilizes；The solidifying oil of oil suction is high-efficient, and oil suction coagulates oil mass greatly and not will cause secondary pollution, can be widely applied to marine oil spill oil suction
The preparation field of solidifying light wood material.
