[0047] Specific examples of the mesh aperture of the porous stainless steel mesh base include: 30 μm, 35 μm, 40 μm, 50 μm, 55 μm, 60 μm, 65 μm, 70 μm, 80 μm, 90 μm, 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, 150 μm , 180μm, 200μm, 220μm, ...

Embodiment 1

[0060] (1) Clean the base of 200-mesh stainless steel mesh (the pore size of the mesh is 75 μm) with acetone and absolute ethanol for 5 minutes, then take it out and dry it for later use;

[0061] (2) Weigh 12.1g (0.06mol) of 1-dodecanethiol, dissolve it in 200mL of 2-propanol, and prepare a 0.3mol / L solution of 1-dodecanethiol-2-propanol;

[0062] (3) Immerse the stainless steel mesh substrate in (1) in 0.3mol / L 1-dodecanethiol-2-propanol, and react at 25°C for 2h;

[0063] (4) Take out the stainless steel mesh base that has been reacted for 2h, and rinse the impurities adhered to the surface with deionized water, and dry to obtain superhydrophobic stainless steel mesh A1 (1-dodecane grown on the porous copper mesh substrate in situ The content of mercaptan is 4.7% by weight).

[0064] figure 1 This is the thermogravimetric (TG) picture of the treated stainless steel mesh. The thermogravimetric results show that there is a very obvious weight loss peak in the temperature ra...

Abstract

The invention relates to the field of oil-water separation materials, and discloses a stainless steel mesh for oil-water separation, a preparation method and applications thereof. The stainless steelmesh for oil-water separation comprises a porous stainless steel mesh substrate and alkyl mercaptan growing on the porous stainless steel mesh substrate in situ. According to the stainless steel meshfor oil-water separation, used raw materials are non-toxic, cheap and easy to obtain, the preparation method is simple and easy to operate, does not require a high-temperature roasting process, and issuitable for industrial production, and the stainless steel mesh for oil-water separation is stable in physical and chemical properties and can be continuously used for a long time.

Description

technical field [0001] The invention relates to the field of oil-water separation materials, in particular to a stainless steel mesh for oil-water separation and its preparation method and application. Background technique [0002] The security and supply of energy has always been one of the most difficult problems for human beings. Today, oil is still the main source of energy in the world. Due to factors such as evaporation loss, leakage, leakage, etc., a certain amount of loss will occur during the process of oil exploitation, transportation, processing, storage, sale, and use. It is estimated that about 0.5% of the world's oil products enter the water body every year, and the direct economic loss exceeds 7 billion US dollars, and the economic loss caused by water pollution is difficult to estimate. At the same time, offshore oil spill accidents and ship oil spill accidents occur from time to time. Such accidents often produce a large amount of oily sewage in a short per...
