Porous multilayer separator and manufacturing method thereof |
| abstract |
The present invention relates to a process for producing a polymer composition, comprising the steps of: a) dispersing an inorganic filler in a first polymer substance having a melting point of 140 ° C or lower and melt-kneading the same, and b) dispersing an inorganic filler in a second polymer substance having a melting point of 150 ° C or higher, preparing the melt-kneaded product obtained in step b); Molding the multilayer sheet through the co-extrusion method of the melt-kneaded product obtained in steps a) and b); Forming a porous multilayer sheet by forming pores while separating the interface between the polymeric material and the inorganic filler in each layer through a step of stretching the multilayer sheet; And a step of thermally fixing the porous multilayer sheet. The present invention provides a simple and efficient process for producing a porous multilayer separator. |
