Nylon-based super-hydrophobic sewage filtering bag and preparation method thereof

Abstract

The application relates to the technical field of sewage treatment, and discloses a nylon-based super-hydrophobic sewage filtering bag and a preparation method thereof, which comprises a nylon-based cloth layer, a super-hydrophobic layer and a porous activated carbon fiber membrane; the super-hydrophobic layer is prepared by the following steps: firstly, the nylon-based cloth layer is subjected to plasma treatment, and then the nylon-based cloth layer is immersed into a solution containing nano materials and low-surface-energy substances, so that a super-hydrophobic layer formed by nano silicon dioxide particles and low-surface-energy substances is formed on the surface of the nylon-based cloth layer; the nano materials are modified nano silicon dioxide and modified graphene, and the low-surface-energy substances are fluorine-containing acrylate polymers; under the premise of ensuring high performance, the production cost is reduced, and the large-scale industrial production and popularization and application of the nylon-based super-hydrophobic sewage filtering bag are facilitated.
