Abstract

The present invention discloses a material used for rapid separation of oil and water and preparation method and application thereof, the mesh material is placed into monomer solution, reacting with the presence of initiator to prepare material used for rapid separation of oil and water. The monomer is divinylbenzene or 2-(dimethylamino) ethyl methacrylate, and the mesh material is stainless steel mesh. The present invention modifies the functional small molecules and polymers to the surface of the materials, thereby preparing multifunctional composite materials, effectively separating oil-water emulsion, so as to achieve the purpose of oil-water separation.

First claim

The invention claimed is:

1. A preparation method of a material used for separation of oil and water, the method consisting of the following steps in a sequential order without any additional steps:
providing a mesh material, the mesh material being a stainless steel mesh;
cleaning the mesh material with an organic solvent;
treating the mesh material with an acid;
treating the mesh material with a silanating agent;
placing the mesh material into a monomer solution; and
reacting the monomer with the presence of an initiator at between 60 to 80° C. and for between 15 to 30 hours to prepare the material used for separation of oil and water,
wherein the monomer is 2-(dimethylamino) ethyl methacrylate;
wherein the initiator is azobisisobutyronitrile; and
wherein the mass ratio of the monomer and the initiator is 40:0.5 to 40:2.

2. The preparation method of the material used for separation of oil and water according to claim 1 , wherein the organic solvent is ethanol or acetone.

3. The preparation method of the material used for separation of oil and water according to claim 1 , wherein the acid is hydrochloric acid.

4. The preparation method of the material used for separation of oil and water according to claim 1 , wherein the silanating agent is vinyltrichlorosilane.
