Preparation method of aluminum blades used in oil skimmer loaded with oleophilic and hydrophobic composite materials

Abstract

The invention discloses a method for preparing aluminum blades used in an oil receiving machine with oil-wet and hydrophobic composite materials. According to the method, ultrafine graphene nanosheetsare prepared by a microwave expansion method, and polytetrafluoroethylene-graphene nanosheet composite material powder is prepared; then the composite material powder is subjected to compression moulding forming and the surface chemical reduction to obtain polytetrafluoroethylene-graphene composite material slices; and finally, the polytetrafluoroethylene-graphene composite material slices and aluminum sheets are bonded with fluorine resin primer, and after drying is completed, the aluminum blades used in the oil receiving machine with the oil-wet and hydrophobic composite materials are prepared. The method for preparing the aluminum blades used in the oil receiving machine with the oil-wet and hydrophobic composite materials is simple, simple and convenient to operate and low in cost, the prepared aluminum blades used in the oil receiving machine with the oil-wet and hydrophobic composite materials have good oil-wet and hydrophobic performance, high oil-receiving efficiency, high mechanical bond strength and high corrosion resistance, and the recovery and disposal of oil slick can be greatly promoted.

Description

technical field

[0001] The invention relates to a method for preparing aluminum blades used in oil skimmers loaded with lipophilic and hydrophobic composite materials. Background technique

[0002] With the rapid development of my country's economy, the demand for crude oil is increasing day by day, and the ecological pollution accidents of oceans, rivers and lakes caused by crude oil leakage are also becoming more and more serious. After a crude oil spill accident occurs, it should first be surrounded by oil booms to prevent it from spreading on the surface of the water body, so as to facilitate the subsequent use of mechanical treatment, chemical treatment, bioremediation technology, combustion treatment, adsorption treatment and other technologies Carry out oil slick cleanup. The chemical treatment method mainly uses chemical agents such as dispersants, oil coagulants, and demulsifiers to demulsify the oil film floating on the surface of the water body. However, this met...
