Problems solved by technology

[0004] At present, most superhydrophobic / oleophilic or superoleophobic / hydrophilic materials are modified with sponge as the matrix to achieve the purpose of hydrophobicity, so as to realize oil-water separation. An invention patent for the preparation method of nanotube-reinforced superhydrophobic ethylcellulose sponge, using ethylcellulose as the material for oil-water separation, and synergistically strengthening the sponge matrix by cross-linking and introducing carbon nanotubes, the resulting superhydrophobic porous Sponge has the advantages of excellent oil absorption, stability, recyclability and biodegradability, etc., but the elasticity of the modified sponge becomes poor, shortens its service life, and has poor reusability, and the preparation method is complicated and time-consuming. Long, and the scope of application is limited, which reduces the production efficiency and increases the labor force in actual production

Description

technical field [0001] The invention belongs to the technical field of oil-water separation materials, and in particular relates to a preparation method and application of a hydrophobic material based on nanoparticles. Background technique [0002] Oil spill pollution in crude oil extraction, transportation and processing is a serious problem facing global water pollution. For example, the crude oil spill in the Gulf of Mexico in the United States in 2010 was the most serious oil spill in the history of the United States. In addition to huge economic losses, it also caused devastating environmental and ecological disasters. [0003] Traditional oil pollution treatment methods, such as using chemical dispersants, incineration, oil skimmers, etc., not only consume time and energy, but also cause secondary pollution problems, and have been gradually eliminated. However, the organic matter that causes oil pollution includes not only light oil floating on the water surface, depo...
