Crosslinked polyolefin separator and manufacturing method thereof |
| abstract |
The present invention comprises the steps of preparing a (S1) silane-grafted polyolefin composition; (S2) extruding the silane grafted polyolefin composition, molding and stretching into a sheet form; (S3) extracting a diluent from the stretched sheet to prepare a porous membrane; (S4) heat-setting the porous membrane, wherein the draw ratio in the TD direction (Transverse Direction, width direction of the sheet) at the time of heat setting is adjusted to be 1.5 times or more afterwards, and then adjusted to decrease while the heat setting is in progress; And (S5) water-crosslinking the heat-set porous membrane; and a method for preparing a crosslinked polyolefin separator and a silane crosslinked polyolefin separator. The present invention can provide a separator having a high melt down temperature and an improved heat shrinkage rate at the same time. |
