Problems solved by technology

However, this kind of separator has the disadvantages of large pore size and low strength, which can easily cause the separator to "penetrate" and lead to a short circuit on the plate, resulting in the scrapping of the battery; Therefore, when using this kind of separator, the quality requirements of the polar plate are very strict, the polar plate must not have burrs and bumps, and the polar plate cannot be bent, otherwise the separator will be damaged and the battery will fail

Abstract

The lead-acid actuating storage battery separator overcomes the problems of large bore and low strength in common 10G separator, which comprises following material as weight share: 100 ultrathin glass-fiber wool of 1.0~1.4ª–m diameter, 10~15 polyester fiber of 6~9ª–m diameter, 0.2~0.3 wet strength agent, 6~7 precipitation latex, and 0.3~0.4 cationic polyacrylamide. This production holds traditional advantages, reduces maximal bore diameter 30~50%, and improves almost 1 time of tensile strength, 80% dry breaking strength and 65% corrosion breaking strength.

Description

technical field [0001] The invention relates to a storage battery material and a preparation method, in particular to a separator in a lead-acid storage battery for automobile starting and a preparation method thereof, belonging to the technical field of storage batteries. Background technique [0002] The separator is an important component of the lead-acid battery. The separator is placed between the positive and negative plates of the battery, which can not only prevent the short circuit of the electrodes in the electrolyte, but also ensure that the electrolyte has good conductivity between the positive and negative electrodes. , It also has the functions of reducing the bending of the plate and preventing the active material from falling off. With the rapid development of the automobile industry, the performance requirements for starter lead-acid batteries are getting higher and higher. As one of the four major components of lead-acid batteries, the performance of the se...
