| titleOfInvention | A kind of preparation method of anticoagulation hemodialysis membrane |
| abstract | The present invention relates to a kind of preparation methods of anticoagulation hemodialysis membrane, polyvinylpyrrolidone and deionized water are added in reaction kettle with 0.01~0.2:1 in mass ratio, hydrolyst is added to flow back at a temperature of 55~95 DEG C 1.5~2h, obtains the modified polyvinyl pyrrolidone with carboxyl and amido active group；Hemodialysis membrane after cleaning is immersed in modified polyvinyl pyrrolidone aqueous solution, soaking time control takes out in 0.5~50h and stands, dries；Hemodialysis membrane is soaked in cross-linking agent solution and carries out cross-linking reaction, the functional layer containing modified polyvinyl pyrrolidone group is obtained inside haemodialysis film surface and fenestra；First with n-hexane, again with ethyl alcohol, finally modified hemodialysis membrane is cleaned with deionized water, go out remaining reactant and solvent.The present invention forms stable anticoagulant functions layer inside haemodialysis film surface and fenestra, can improve haemodialysis film properties. |
