| titleOfInvention | Method for producing porous membrane |
| abstract | Disclosed is a technique for producing a porous film having a high porosity, which has properties suitable for a reflective sheet excellent in bending workability and peeling resistance. 5 to 70 parts by weight of a composition containing polyolefin and inert fine particles, wherein the weight ratio of polyolefin to inert fine particles is 25 to 2:75 to 98, and the boiling point at atmospheric pressure is less than 200 ° C. A solution comprising 30 to 95 parts by weight of a volatile solvent is prepared, and the solution is extruded from a die in a temperature range of the melting point to the melting point + 60 ° C. of the polyolefin composition to obtain an extrudate, and then the extrudate is cooled to be a gel The porosity of the molded article is 70 to 95 volume by further drying and removing all or part of the solvent contained in the gel-like molded article, and then stretching the dried molded article. % Porous membrane production method.
