The producing method is simple, no wastewater is discharged, and the producing method can meet the requirement for clean production.

A kind of preparation method of hydroxyanthraquinone extracorporeal circulation modified membrane
The invention provides a preparation method of a hydroxyanthraquinone extracorporeal circulation modified membrane. The present invention first chloromethylates polysulfone / polyethersulfone / polyester to prepare chloromethylated polysulfone / polyethersulfone / polyester, then chloromethylates polysulfone / polyethersulfone / polyester with Phthalimide, DMF and sodium hydride are mixed to prepare phthalimide polysulfone / polyethersulfone / polyester, and then phthalimide polysulfone / polyethersulfone / polyester Aminomethylation of ester to obtain aminomethylated polysulfone / polyethersulfone / polyester, and then graft 1,8-dihydroxy-3-carboxyanthraquinone to aminomethylated polysulfone / polyethersulfone / polyester On the ester, obtain hydroxyanthraquinone modified polysulfone / polyethersulfone / polyester, and finally prepare hydroxyanthraquinone modified polysulfone / polyethersulfone / polyester into hydroxyanthraquinone modified polysulfone by immersion precipitation phase inversion method / polyethersulfone / polyester membrane. The method has simple steps, can be used for industrial batch production, and solves the existing technical problem of high hemolysis rate of biological materials.
