Abstract

The invention relates to the field of lubricating oil, and particularly discloses uniform and stable separator oil and a preparation method thereof. The uniform and stable separator oil is prepared from, by weight, 20-30 parts of paraffin-based base oil, 25-35 parts of naphthenic base oil, 15-20 parts of rubber filling oil and 20-30 parts of additives, and the additives comprise, by weight, 10 to 20 parts of pentaerythritol and 20 to 30 parts of binary acid. The preparation method comprises the following steps: preparing the base oil; and adding the additive into the base oil, and carrying out ultrasonic mixing treatment to obtain the separator oil. The separator oil provided by the invention can be used for a storage battery, and has the advantages of good thermal stability and high-temperature oxidation resistance.

Description

technical field [0001] The present application relates to the field of battery filling oil, more specifically, it relates to a uniform and stable separator oil and a preparation method thereof. Background technique [0002] In daily life, the batteries commonly used for charging and discharging include not only lithium batteries, but also lead-acid batteries. In order to make the positive and negative electrodes as close as possible and not easy to short circuit due to contact, a separator is placed between the positive and negative electrodes to separate the positive and negative electrodes. [0003] Separators for storage batteries are generally required to have porosity and permeability. Because polypropylene separators have better porosity and permeability, they have become one of the most widely used separators at present. Polypropylene separators are usually made of powdered polypropylene, carbon black and separator oil, etc., and are made by mixing, roller pressing a...
