Description
Technical field
The present invention relates to a kind of super-hydrophobic cavernosa material and preparation method thereof.
Background technology
With economic rapid growth, the petroleum consumption cumulative year after year of China, external dependence degree also expands year by year, in order to
Reduce dependence of China's economic development to oil exporting country, in recent years, China more payes attention to the exploitation of offshore oil, but therewith
What is come is increasing sea oil spill accident, causes serious energy waste, environmental pollution or even potential safety hazard.According to statistics,
The spilling oil mass of China littoral sea ship and offshore drilling platform oil spill accident in recent years is up to 37000 tons or so, wherein 50 tons
Major oil spill accident above has 69, about 8000 tons of an oil spillage of most serious.Moreover, by artificial origin and nature
The oil leak that the factors such as corrosion are caused shows ascendant trend year by year.These all further exacerbate China's oil shortage of resources
Situation, seriously constrains domestic economy sustainable development, causes serious ecological environment disaster.Therefore, in order to ensure China
The sustainable stable development of Petroleum Industry, is oil in the urgent need to researching and developing the oil loss control technology with independent intellectual property right
The engineering that gas is reclaimed and oil leak Emergency recovery is equipped smoothly is implemented to lay the foundation.
In spill response control operation process, the larger heavy oil of commercial oil skimmer processing viscosity is highly effective but right
In the less oil of viscosity, because the oily collection mode that encloses for the features such as its diffusion area is big, oil reservoir is thin, being difficult with traditional comes clear
Reason.Secondary destruction or pollution are not only brought to ecological environment using means such as dispersant, microorganism eutrophication and burnings, and
Waste the energy oil product of worsening shortages.Adsorption separation technology is as a kind of principle is ripe and the oil loss of economical and efficient the most
Control device, it is considered to be one of main flow direction of oil spilling control technology development.This technology it is crucial with adsorbing separation material
The exploitation of material, traditional oil spilling handles sorbing material based on activated carbon, asphalt felt and a variety of natural plants, goes out again in recent years
Macroporous absorption material (CN 103951843 A, the 2014.07.30, full text using macromolecule sponge as substrate are showed；CN
