Method.
Background technology
With the fast development of petroleum chemical industry, caused big gauging during oil exploitation, refining, oil product transport etc.
Class is revealed and industrial organic solvent pollution causes serious destruction, traditional oil absorption material or oil suction to water ecological environment
Ability is low, poor selectivity, or preparation technology is complicated, expensive, can not meet extensive waste oil recovery and environmental improvement
Need.The use of new material and new technology brings facility, and surface, which is modified, to be by functional small molecule or polymer-modified arrive
In two dimension or three-dimensional carrier material surface, so as to prepare the composite of surface modification.Wherein, at due to functional molecule
In the surface of original material, therefore, the main property of composite depends primarily on the property of surface molecular.For example, by some
Hydrophobic chemical molecular is modified onto water wetted material surface, it is possible to which its surface hydrophilicity is changed over into hydrophobicity.At present, its
Method of modifying mainly includes two classes：When：Physically encapsulation, two：Chemical modification.Physically encapsulation is primarily referred to as the methods of spin coating will be poly-
Compound modification stops surface to load.Chemical modification is to be modified carrier surface by being chemically reacted between organic molecule.Surface material
Compatibility, interface binding power between material and carrier material are the keys of surface modified composite material stable performance.Melamine
Foam be with melamine and oxymethylene polymerization into high polymer material, there is soft outside but hard inside characteristic, have very strong molecular level to rub
Function is wiped, there is good sound insulation, sqouynd absorption lowering noise effect, and melamine due to its unique space three-dimensional network structure
Itself also has nitrogen, can be decomposed when meeting high temperature and discharge nitrogen, reduce the concentration of fuel gas, while immediately on surface
The dense coke layer of retardance burning is formed, when naked light leaves i.e. automatic distinguishing；Because it has good heat endurance, chemistry is surely
It is qualitative, anti-flammability, high resiliency etc., it is had popularity in life, meanwhile, its three-dimensional porous structure, become system
The preferable carrier of standby sorbing material.But can not for oil water mixture as a kind of amphipathic nature material, melamine foamed plastic
Selective absorbing, therefore, it is limited in profit processing and the application separated.
Graphene has the strong good characteristic of hydrophobicity, using the special surface property of graphite ene coatings, with porous polymeric
Thing does bed material, hydrophobic modified to the progress of its surface, can obtain the hydrophobic water-oil separating material of oil suction, but existing all kinds of emerging
Adsorption capacity is relatively low, water-oil separating performance is poor and graphene layer is easily de- caused by because of material and technique for material still presence
The problems such as fall.Therefore it provides it is a kind of with superpower hydrophobic performance and oil absorbency, that adsorbance is big, stability is good is super
Hydrophobicity melamine bubble silk floss and its manufacture method.
The content of the invention
Have that superpower hydrophobic performance and oil absorbency, adsorbance be big, stability it is an object of the invention to provide a kind of
