Abstract

The invention discloses a sealing compound for a zinc-manganese battery and a preparation method of the sealing compound, and belongs to the technical field of a battery sealing material. The sealing compound for the zinc-manganese battery is prepared from the following raw materials in part by weight: 20 to 30 parts of hydrogenation saturated polybutylene, 30 to 40 parts of modified epoxy resin, 40 to 50 parts of asphalt, 20 to 30 parts of 120 solvent gasoline, 10 to 20 parts of aromatic oil, 20 to 30 parts of nonylphenol polyoxyethylene ether, 10 to 20 parts of dimethicone, 1 to 5 parts of nano titanium dioxide, and 1 to 5 parts of nano sliced aluminum powder. The invention also provides a preparation method of the sealing compound for the zinc-manganese battery. The sealing compound for the zinc-manganese battery has good adhesion performance, sealing performance and creep resistance and also has anti-aging performance, high-temperature stability and temperature sensitivity; the sealing compound is not deformed and does not flow at a high temperature and is good in adhesion performance and indehiscent at a low temperature, easy to smear, free from peculiar smell and long in service life.

Description

technical field [0001] The invention belongs to the technical field of zinc-manganese battery sealing materials, in particular to a sealing glue for zinc-manganese batteries and a preparation method thereof. Background technique [0002] The zinc-manganese battery is a primary battery with manganese dioxide as the positive electrode, zinc as the negative electrode, and ammonium chloride aqueous solution as the main electrolyte. It is commonly known as a dry battery and is also called a Leclanche battery in academia. Zinc-manganese batteries are also called alkaline dry batteries, alkaline zinc-manganese batteries, and alkaline manganese batteries. If the sealing performance of the zinc-manganese battery is not good, the water in the electrolyte will volatilize and affect the normal operation of the battery; at the same time, the oxygen in the air will also enter the interior of the battery to oxidize the zinc and reduce the service life of the battery. It can be seen that t...
