METHOD FOR PREPARING POLYMER RESIN COMPOSITION FOR PRODUCING FILTRATION MEMBRANE HAVING IMPROVED HYDROPHILICITY AND MECHANICAL STRENGTH

摘要

Disclosed are a polymer resin composition for filtration membrane production capable of improving the physical strength of a hydrophilized polymer filtration membrane, particularly a polymer resin composition for filtration membrane production which not only improves the physical strength of a hydrophilized polymer filtration membrane but also uses additives used to allow for higher hydrophilicity, and a polymer filtration membrane production method using same. The present invention provides a method for preparing a polymer resin composition for filtration membrane production and a polymer filtration membrane production method using same, the method for preparing a polymer resin composition for filtration membrane production comprising the steps of: (a) mixing a hydrophobic polymer base resin, a first solvent, and a hydrophilic organic additive so as to prepare a polymer solution; (b) preparing a hydrophilic inorganic additive in the form of a sol; and (c) adding the hydrophilic inorganic additive to the polymer solution.
