A kind of preparation method of cuprous oxide/melamine sponge used for oil spill recovery

Abstract

The invention discloses a preparation method of cuprous oxide / melamine sponge for recycling oil spill; high-hydrophobic high-oleophilic sponge is prepared by compositing cuprous oxide and melamine, wherein Dow Corning silica gel is used as a binder to more tightly bind cuprous oxide and melamine, Dow Corning silica gel is also used as a modifier, and hydrophobicity of the melamine sponge can be further improved. The sponge is prepared mainly by compositing melamine sponge as a carrier to cuprous oxide, the hydrophobicity and oleophilicity of the sponge are judged through contact angle test and oil-water adsorption test, and the composition condition of the cuprous oxide on the surface of the modified melamine sponge is characterized through an SEM (scanning electron microscope). The preparation process is simple, the cost is low, the prepared material has good hydrophobicity and oleophilicity, it is easy to desorb and recycle oil, reuse is available, and the sponge may be effectively applied to the controlled recycling for oil spill incidents.

Description

technical field [0001] The invention belongs to the technical field of preparation of modified melamine sponge materials, and in particular relates to a preparation method of an oil-water separation material based on superhydrophobic and lipophilic modification of melamine sponge by cuprous oxide for oil spill control and recovery. Background technique [0002] Once an oil spill occurs, it will not only cause serious environmental pollution, but also cause serious economic losses. The oil spill in the Gulf of Mexico in 2010 was the most serious oil spill in recent years, seriously polluting the coastline The waters have caused unimaginable harm to the creatures in the ocean, and the adverse effects of oil spills may last for decades. In addition to the harm to the economy and the environment, oil spills may also cause fires , The traditional oil spill treatment methods include mechanical extraction and separation, chemical dispersion, and on-site combustion. These methods a...

Problems solved by technology

For example, although the adsorption material composited with carbon nanotubes has high oil-water separation ability, its expensive production cost limits its wide application.

Due to its water absorption characteristics, activated carbon needs to be modified on the surface to improve its oil absorption efficiency, and its density is high, it will sink in the oil-water mixture, and there are many inconveniences for oil spill recovery.
