Therefore, the development of an oil-water separation material having excellent performance is still a problem to be solved. The filtering type oil-water separation material can efficiently separate oil from water, has excellent comprehensive performance, but has the defects of high cost, complex preparation process, environmental pollution and the like.

However, the mechanical properties of the melt-blown nonwoven fabric as a filter material, such as tensile, compressive and wear resistance, are insufficient, the separation efficiency is low, and the melt-blown nonwoven fabric cannot simultaneously have the problems of high filtration efficiency, low resistance and the like.
In view of the above, the invention provides a method for simply preparing an oil-water separation material based on the advantages of melt-blown non-woven fabrics in the filtration industry.
