Abstract

The invention discloses a preparation method of a ZrO2@PET fiber oil-water separation material. The preparation method is specifically implemented according to the following steps: step 1, coating the surface of a PET fiber with ZrO2 sol by adopting a dip coating method, centrifuging and drying to obtain a PET fiber with a ZrO2 gel layer; step 2, putting the PET fiber with the ZrO2 gel layer obtained in the step 1 on a heating table, and converting the PET fiber with the ZrO2 gel layer into the PET fiber with a ZrO2 ceramic layer through a photochemical reaction; and step 3, carrying out chemical modification on the ZrO2 ceramic layer on the PET fiber obtained in the step 2 to obtain the ZrO2@PET fiber oil-water separation material. The ZrO2@PET fiber oil-water separation material prepared by the method has an excellent separation effect on low-density oil/water and high-density solvent oil/water mixed liquor, and solves the problems that the existing oil-water separation material is low in separation efficiency, poor in corrosion resistance and incapable of being recycled.

Description

technical field [0001] The invention belongs to the technical field of preparation of oil-water separation materials, in particular to a ZrO 2 Preparation method of @PET fiber oil-water separation material. Background technique [0002] With the increasing demand of human beings for oil, oil leakage accidents frequently occur in the process of oil exploitation, transportation and processing. These leaked oil products will inevitably cause great pollution to the water resources on the earth. In addition, the discharge of some oily organic solvents (such as chloroform, chlorobenzene, methylene chloride, etc.) in industrial production has also caused increasingly serious harm to our water resources. The recovery of leaked and discharged oil products through oil-water separation technology is the only effective way to solve the above environmental problems. Compared with traditional oil-water separation methods such as centrifugation, gravity separation, and coagulation sedim...
