Process for producing cellulose-nanofiber-filled microporous stretched polyolefin film, microporous cellulose-nanofiber composite film, and separator for non-aqueous secondary battery |
| abstract |
A process for producing a polyolefin microporous stretched film containing cellulose nanofibers according to the present invention is a process for producing cellulose microparticles by uniformly dispersing a hydroxyl group of a cellulose having a powder particle diameter using a dibasic acid anhydride to a plasticizer to obtain a cellulose powder dispersion mixture A first step; A second step of melt-kneading the cellulose powder dispersion mixture and the polyolefin to obtain a polyolefin resin composition; A third step of extruding the polyolefin resin composition to obtain an extrusion molded article; A fourth step of stretching the extrusion molded body using a film stretching machine to obtain a film; A fifth step of extracting a plasticizer from the film; And a sixth step of conducting heat fixation for suppressing shrinkage while stretching the film at a temperature not higher than the melting point of the polyolefin raw material after extracting the plasticizer, wherein the biaxial kneading extruder comprises: Only once through. |
