Abstract

The invention relates to the technical field of environmental protection, in particular to an anti-pollution oil-water separation mesh film and a preparation method thereof. The oil-water separation mesh film is formed by coating meshes of a fabric mesh having 100-1800 meshes with one micron-sized organic high-molecular polymer coating film. A plurality of micron-sized mesh holes are reserved in the oil-water separation mesh film, and nanoscale bubbles are arranged on the organic high-molecular polymer coating film. The oil-water separation mesh film provided by the invention is large in water flux, rapid in oil-water separation speed and good in oil-water separation effect, is suitable for treating sewage with high oil content, and has good separation effects on heptane, edible oil, gasoline, n-hexane, carbon tetrachloride and the like; the oil-water separation mesh film is biocompatible, environment-friendly, easy to clean, reusable and good in stability.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an anti-pollution oil-water separation mesh and a preparation method thereof. Background technique [0002] In the context of oil spill pollution in the world today, using the wettability of materials to develop new oil-water separation methods has become a research hotspot, which is of great significance for the protection of the ecological environment, the reuse of resources, and new research on oil-water separation. Hydrophilic and oleophobic mesh can separate oil and water according to the different wettability of the surface to water and oil. It is a new type of separation tool. [0003] The Chinese patent of publication number CN 104759118 A discloses a kind of preparation method of organic high molecular polymer coating oil-water separation net, and this method comprises the following steps: 1) mixing and stirring the polymerization monomer and initiator i...
