Abstract

The invention discloses an anti-fouling high-throughput polysulfone composite membrane. The anti-fouling high-throughput polysulfone composite membrane is prepared from, by weight, 50-80 parts of caprolactam-modified polysulfone, 10-20 parts of sulphonated polysulfone, 2-15 parts of polyvinylidene fluoride, 5-15 parts of polydiphenylmethylene acrylic polyurethane, 1-5 parts of polydiphenylmethylene vinyl polyurethane, 1-3 parts of perfluorinated sulfonic acid resin, 35-80 parts of a solvent, 1-4 parts of polyaniline nanofibers, 1-2 parts of nanometer zirconia, 0.1-0.5 part of nanometer lanthanum oxide, 1-2 parts of nanometer titanium dioxide, 0.2-1.5 parts of a modified boron nitride silane coupling agent, 0.3-1.5 parts of cellulose acetate, 0.5-3 parts of a polystyrene-alt-maleic anhydride copolymer and 0.5-3 parts of carboxyl betaine methacrylate. The anti-fouling high-throughput polysulfone composite membrane is good in thermal stability, excellent in weather resistance and anti-fouling performance and high in throughput.

Description

technical field [0001] The invention relates to the technical field of membrane materials, in particular to an anti-pollution high-flux polysulfone composite membrane. Background technique [0002] Polysulfone materials are a class of widely used membrane materials, including polysulfone, polyethersulfone, polyphenylene sulfide sulfone, etc. and their sulfonated or chloromethylated products, which have excellent thermal stability, oxidation resistance and Excellent mechanical properties and outstanding separation properties have been widely used as support materials for commercial microfiltration, ultrafiltration, reverse osmosis and nanofiltration membranes. Due to the non-hydrophilic nature of polysulfone, compared with other hydrophilic materials, it has the disadvantages of low flux and fast pollution, which limits the application of polysulfone membrane materials. Contents of the invention [0003] Based on the technical problems in the background technology, the pre...
