| titleOfInvention | The preparation method of enhanced sponge structure hollow-fibre membrane |
| abstract | The invention discloses a kind of preparation method of enhanced sponge structure hollow-fibre membrane, include the following steps: that fiber filament 1) is woven into hollow tube using control of two-dimensional braided technology or crochet techniques, using it as reinforcement；2) hydrophobic additive, toluene di-isocyanate(TDI), organic silicone oil, organo-tin catalyst and amines catalyst are uniformly mixed according to different addition order, obtain casting solution；3) reinforcement that step 1) obtains is infiltrated in distilled water, soaks its outer surface sufficiently, obtain pretreated reinforcement；4) sheath core composite spinning technology is utilized, pretreated reinforcement and casting solution are coextruded from annular spinning head, through Water blown, curing, obtains enhanced sponge structure hollow-fibre membrane.This method has the oil suction hollow fiber porous film of sponge structure using situ aggregation method preparation, improves interface bond strength between functional layer and supporting layer, improves water-oil separating efficiency. |
