| titleOfInvention | A preparation method of TiO2-SiO2@PDMS composite superhydrophobic filter material |
| abstract | The invention discloses a preparation method of TiO 2 ‑SiO 2 @PDMS composite super-hydrophobic filter material, belonging to the field of super-hydrophobic filter material preparation. In this method, the organically modified titanium dioxide sol is firstly obtained by the sol-gel method, and then fumed silica is added to construct a multi-scale rough structure, and polydimethylsiloxane is introduced into the TiO 2 ‑SiO 2 mixed sol to improve The bonding strength between the fiber filter material and TiO 2 and SiO 2 particles reduces its surface energy at the same time, so as to obtain a super-hydrophobic filter material with strong hydrophobic performance, high mechanical strength and good chemical stability, and the hydrophobic coating is uniform on the surface of the fiber Adhesion, with a regular rough structure, makes the filtration efficiency and filtration resistance of the filter material achieve a better balance, increases the quality factor, and improves the filtration performance. The composite super-hydrophobic filter material prepared by the invention can effectively solve the technical problems such as sticky bags and difficulty in cleaning dust produced by the bag filter when processing dust with a high moisture content. |
