Abstract

The present invention relates to a kind of storage battery PE separator production process, has the following steps: (1) weigh raw material according to weight part number; ‑60min, the mixing temperature is 45°C; (3) Secondary mixing: add process oil to the raw materials after the primary mixing, so that the process oil accounts for 60% of the weight of the mixing, and then mix at 80‑120r / min Mixing and stirring for 10-30min at a certain speed, the mixing temperature is 35°C; (4) Add the mixed material to the extruder and extrude the PE separator semi-finished product; (5) Process the PE separator semi-finished product through a five-roll calender After pressing and shaping, the semi-finished PE separator with reinforcing ribs is obtained; (6) the semi-finished PE separator with reinforcing ribs is cooled, oiled and rolled to obtain the PE separator, and the PE separator produced by it has a service life Long and extensible.

Description

technical field [0001] The invention relates to the technical field of a separator in a lead-acid battery, in particular to a production process of a battery PE separator with an improved process method. Background technique [0002] The lead-acid battery PE separator (hereinafter referred to as the PE separator) is a component that is immersed in the electrolytic solution (generally sulfuric acid solution) of the lead-acid battery to isolate the positive and negative electrodes. The clapboard has gone through the process from wooden clapboard to rubber clapboard, PVC, glass fiber clapboard to the current PE clapboard. The structure of the PE separator used in modern times is usually a bag-like structure, in which electrodes are arranged, and stepped ribs are arranged on the side close to the electrodes. In "Lead-Acid Battery Separator", publication time: 2010-11, publisher: Chemical Industry, author: Shi Guang, Chen Hongyu. The book fully introduces the history of the lea...
