Heat-resistant leakproof sealant of alkaline storage battery

Abstract

The invention discloses a heat-resistant leakproof sealant of an alkaline storage battery. The heat-resistant leakproof sealant is prepared from, by weight, 8-15 parts of molybdenum-containing phenolic resin, 20-40 parts of butyl rubber, 10-16 parts of high density polyethylene, 3-6 parts of ethylenediaminetetraacetic acid, 2-8 parts of gas phase titanium dioxide, 0.5-1.5 parts of 2,5-ditert-butylhydroquinone, 1-2 parts of ferric chloride, 9-14 parts of 1,4-cyclohexanedimethanol, 2-6 parts of methyl methacrylate, 5-9 parts of calcium stearate, 4-7 parts of Tween 40, 5-10 parts of triallyl isocyanurat, 10-15 parts of inorganic additive, 2-6 parts of N-phenyl-beta-naphthylamine and 12-20 parts of water. According to the heat-resistant leakproof sealant of the alkaline storage battery, a sealing material formula with good heat resistance is obtained through many times of experiments, the heat-resistant leakproof sealant is used in the processing, production and maintenance process of the alkaline storage battery, the sealing effect is good, and the ageing resisting performance is good.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a heat-resistant and leak-proof sealant for alkaline accumulators. Background technique [0002] Alkaline battery is a battery with sodium hydroxide and potassium hydroxide solution as the dielectric. It has the characteristics of small size, high mechanical strength, stable working voltage, high current discharge, long service life and easy to carry, so it has achieved rapid development. development of. Alkaline battery is an industrial product with a wide range of uses and a huge demand. During the production process, the tank cover connection and wiring parts of the battery are generally sealed with adhesive sealing materials. With the increasing market demand for batteries, more and more attention has been paid to the treatment of waste batteries and the maintenance of batteries, and the key to battery maintenance is to open the sealing cover without damaging the batter...
