Embodiment Construction

[0026] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0027] The present invention provides a kind of production method of PVC battery separator, and the method step comprises:

[0028] In the first step, polyvinyl chloride resin is mixed with plasticizer and then mixed with silica toner at high speed to form a mixture;

[0029] The second step is to add a solvent to the mixture, so that the solvent material is completely absorbed into the mixture to form a wet powder mixture;

[0030] The third step is to transport the mixture in wet powder state to the extruder for low temperature extrusion;

[0031] The fourth step is to emboss the mud material coming out of the die of the extruder on the calender to form the initial state partition;

[0032] The fifth step is to put the initial state separator into the extraction tank to extract the aforementioned solvent to form a microporous ...

Abstract

The present invention discloses a PVC battery separation plate production method and a PVC battery separation plate, wherein the method and the separation plate are used in the battery separation plate fields of the fields of lead-acid storage batteries and lead-acid gel storage batteries. According to the present invention, with the mixing and the extraction of the solvent and the combination of various process steps, the battery separation plate has high porosity zone and small and ideal pore size distribution; and with the matrix of the PVC polyvinyl chloride resin, the PVC polyvinyl chloride resin has characteristics of good penetration resistance, good resilience, good compressive strength, and good toughness.

Description

technical field [0001] The invention relates to a battery separator in the field of lead-acid batteries and lead-acid colloidal batteries, in particular to a production method of a PVC battery separator and the PVC battery separator. Background technique [0002] Lead-acid batteries are generally divided into three categories, namely, automobile starting batteries, stationary telecommunications, power backup batteries, deep-cycle traction power electric vehicle batteries, and long-life batteries for solar photovoltaic power generation and wind power generation. With the development of batteries, battery separators are also constantly evolving and improving. In the 1950s, car start-up batteries mainly used wooden separators. Because the separators were not resistant to oxidation and corrosion in sulfuric acid, the battery life was short. Microporous rubber separators appeared in the mid-1960s. Because of their good acid resistance and oxidation resistance, they significantly ...
