Preferably, described antioxidant is the one in BHA or BHT.
Prepare in power 1-4 that any one does not need the method for the PE dividing plate of paint process, comprise the following steps:
A. batch mixing: take raw material by proportioning, by the silicon dioxide in raw material, ultra-high molecular weight polyethylene, Masterbatch, antioxidant, joins in batch mixer, first premixed 10 ~ 20 minutes, then slowly add extend oil, limit edged mixing 60 ~ 90 minutes, fully mixes material;
B. extrusion molding: the raw material mixed is transported in extruder by feeder, through double screw extruder extrusion sheet, more compressing, extrusion need add extend oil again, makes oil content in dividing plate reach between 60 ~ 75%;
C. to pump stripping: the PE dividing plate after shaping enters oil pumper and carries out oil pumping process to it, through the PE dividing plate oil content of oil pumping process 10 ~ 20%, product porosity is 60 ± 5%;
D. heated-air drying: by the baffle surface coating high temperature resistant surfactant through oil pumping process, then drying process, make dividing plate water content between 2 ~ 6%;
E. hole winding is examined: the dividing plate after paint carries out inspection hole through optics inspection hole instrument and to process and length is wound into a roll according to the rules after marking;
F. following process: PE dividing plate is carried out cut, make finished product.
Technical purpose of the present invention is open a kind of PE dividing plate and production method not needing paint process, by adding resistant to elevated temperatures surfactant, reach the effect that finished product PE dividing plate is wetting, and cancel paint, heated-air drying two operations in conventional production methods, effectively can reduce energy consumption.
