Preparation method of high molecule microfilter membrane and porogenic agent

The invention relates to a method for preparing macromolecule micro filter film with phase shift method and relative holing agent. Wherein, it uses the multicomponent macromolecule homogeneous phase system of diglycolic acid maleate as the casting film solution; uses the polymer deposit (dry-wet met...

description	The invention relates to a method for preparing macromolecule micro filter film with phase shift method and relative holing agent. Wherein, it uses the multicomponent macromolecule homogeneous phase system of diglycolic acid maleate as the casting film solution; uses the polymer deposit (dry-wet method) method emerged into non-solvent bath to prepare the micro filter film, while the dry method costs 2mins; the micro filter film has symmetry holes, high strength and insensitivity on temperature and humidity vibration. The aperture of micro filter film is 0.1-0.80micrometer, the water osmosis is 5-150ml/cm2.min (0.1MPa), the whole rate is 70-85%. The invention has wide application.
