Abstract

The invention relates to the technical field of new environment-friendly materials, in particular to a preparation method of an anti-pollution and super-hydrophilic oil-water separation mesh. The preparation method comprises the following steps: adding graphite oxide into an organic solvent to obtain a graphene oxide solution; adding a film-forming material into the graphene oxide solution, and evenly stirring; then, adding a crosslinking agent and a surface active agent, and heating to obtain a polymer solution; soaking a stainless steel mesh into the polymer solution, and drying the soaked stainless steel mesh by heating so as to obtain the anti-pollution and super-hydrophilic oil-water separation mesh. The anti-pollution and super-hydrophilic oil-water separation mesh prepared by the invention has the characteristics of being anti-pollution, high in mechanical strength, obvious in dynamic oil-water separation effect, low in preparation cost, and the like, and has good commercial prospect in the technical field of special infiltration interfaces.

Description

technical field [0001] The invention relates to the technical field of new environmental protection materials, in particular to a preparation method of an anti-pollution super-hydrophilic oil-water separation net. Background technique [0002] Most of the water pollution incidents in recent years are oil pollution, and the oily wastewater is discharged without treatment, which not only affects the safety of the ecological environment, but also causes waste for the recycling and utilization of oil resources. Oil-water separation using the special wettability of solid surfaces to liquids has become a research hotspot today, and the use of special wettability separation filter membranes has gradually become the main measure to solve sewage treatment and oil purification at home and abroad. However, the oil-water separation omentum prepared by this technology currently has the problems of being easily contaminated by oil, poor reusability, and high preparation cost. Contents o...
