Method for continuously producing jelly of ultra-high molecular weight polyethylene porous membrane

Abstract

The invention discloses a method for continuously producing jelly of ultra-high molecular weight polyethylene porous membrane, which is characterized in that the method uses the following steps to complete manufacture continuously: (1) mixing ultra-high molecular weight polyethylene, solvent, and additive into homogeneous material; (2) preparing obtained homogeneous material into jelly membrane; (3) stretching the obtained jelly membrane along two directions to prepare jelly thin membrane; (4) dragging the obtained jelly thin membrane to an extraction tank, removing the solvent by extracting agent, and preparing porous thin membrane; (5) drying; and (6) dragging membrane along two directions to carry out heat shaping, preparing the porous membrane, and finally winding the membrane into a roll. The method for continuously producing jelly of ultra-high molecular weight polyethylene porous jelly membrane can produce continuously and can be controlled easily, the prepared porous membranes features high strength, strong corrosion resistance, low density, low temperature resistance, high alcohol resistance, strong anti-swelling capacity, thereby being widely applied to proton exchange membrane fuel cells, capacitor isolation membrane, various separation membranes and water treatment membrane and other fields.
