Abstract

The invention provides a preparation method of an oil-water separation fabric and a super-hydrophobic fabric prepared by the preparation method. The method comprises the following steps of S1, hydrolyzing tetrabutyl titanate and obtaining titanium dioxide sol; S2, adding siloxane to the titanium dioxide sol for reaction and obtaining modified titanium dioxide sol; and S3, finishing a profiled fiber fabric by adopting the modified titanium dioxide sol and obtaining an oil-water separation fabric. The method provided by the invention is simple in preparation process; and the prepared fabric hasexcellent wear resistance and durability and excellent reproducibility and recyclability, and simultaneously has high oil-water separation efficiency.

Description

technical field [0001] The present invention relates to a preparation method of an oil-water separation fabric and the oil-water separation fabric thereof, in particular to a preparation method of an oil-water separation functional fabric based on a special-shaped polyester fiber fabric, which is durable, recyclable, and has high separation efficiency. Its oil-water separation fabric. Background technique [0002] The treatment of oily sewage has always been an important issue in production and life, and the discharge of oily pollution has seriously affected the ecological environment. Especially in the face of serious oil spill accidents, efficient oil-water separation materials and oil recovery technologies are particularly important. At present, the widely used oil-water separation method is to use porous oil-absorbing materials to absorb oil stains to achieve the purpose of separating from water, such as oil-absorbing felts, oil-absorbing sponges, oil-absorbing paper, e...
