Method for producing polyolefin porous membrane |
| abstract |
The present invention provides a method for producing a polyolefin-based porous membrane in consideration of an environment excellent in extrusion stability and mechanical properties. The present invention extrudes a homogeneous solution in which a polyolefin resin is dissolved in an organic substance capable of forming a uniform solution phase at high temperature and capable of two-phase separation by cooling, and passes through an air gap. In a method for obtaining a polyolefin-based porous membrane by cooling and solidifying a polyolefin-based resin solution in a cooling bath to obtain a polyolefin-based porous precursor, and then extracting the organic material using an extraction solvent, the organic material is a higher alcohol. And the polyolefin resin has a limiting viscosity of 5 to 20 dl / g and a polyolefin resin concentration in the polyolefin resin solution of 5 to 30 wt%. [Selection figure] None |
