Problems solved by technology

This lead-acid battery relies on two different ways to fix the electrolyte, one is AGM technology, that is, the electrolyte is fixed through the AGM separator, and most lead-acid batteries in China use this technology today, but it has a separator with too large aperture Large, poor pressure resistance, easy to cause acid stratification and other shortcomings, are gradually being replaced by another more advanced colloidal fixation technology
[0003] The current separators generally have the defects of low toughness, poor temperature resistance, poor corrosion resistance and flame resistance.

Abstract

The invention discloses a storage battery partition plate and a preparation method thereof. The storage battery partition plate is mainly prepared from the following components in parts by weight: 64.2-65 parts of EW-200 glass fiber plain cloth, 29.8-30.2 parts of a phenolic resin, 0.1-0.7 part of a coupling agent, 5-15 parts of a thermal stabilizer, 0.5-5 parts of a chemical-resistant modifier, 4.6-5.8 parts of barium titanate powder, 2-6 parts of a flame retardant synergist, 5-15 parts of a brominated flame retardant and 3-6 parts of a core-shell acrylic acid elastic emulsion. The partitionplate disclosed by the invention has the advantages of being light in weight, high in strength, good in high temperature resistance and good in corrosion resistance, and is relatively good in flame retardancy and flexibility.

Description

technical field [0001] The invention relates to a storage battery separator and a preparation method thereof, belonging to the field of chemical power sources. Background technique [0002] Lead-acid batteries are widely used, and the output value and output rank first among all kinds of chemical power sources in the world. The representative battery is the valve-regulated lead-acid battery. This lead-acid battery relies on two different ways to fix the electrolyte, one is AGM technology, that is, the electrolyte is fixed through the AGM separator, and most lead-acid batteries in China use this technology today, but it has a separator with too large aperture The shortcomings of large size, poor pressure resistance, and easy to cause acid stratification are gradually being replaced by another more advanced colloid fixation technology. [0003] The current separators generally have the defects of poor toughness, poor temperature resistance, poor corrosion resistance and flame...
