| titleOfInvention | Preparation method of ultra-high molecular weight polyethylene battery separator |
| abstract | The present invention provides a method for preparing an ultra-high molecular weight polyethylene battery separator, comprising the following steps: providing high molecular weight polyethylene, white oil A and white oil B, wherein the white oil A is prepared at a temperature of 40° C. The viscosity is 80-100 mm 2 /s, and the viscosity of the white oil B is less than the viscosity of the white oil A; after the ultra-high molecular weight polyethylene and the white oil A are fed and processed, the process is carried out under heating conditions. Melt extrusion treatment to obtain a base sheet formed by the fusion of the UHMWPE and the white oil A; the base sheet is subjected to replacement-cooling treatment through a cooling roller; the cooled base sheet is longitudinally carried out in turn After stretching, primary transverse stretching, extraction, and secondary transverse stretching, it is heat-set into rolls. |
