Problems solved by technology

[0002] At present, the casing of sealed lead-acid batteries on the market often cracks. This is because during the long-term use of the battery, due to the high temperature, the electrolyte of the battery will flow out, which will affect the sealing quality of the sealing part of the battery casing. The battery casing causes corrosion, damages the battery casing, causes serious damage to the battery, and affects the service life of the battery casing
[0003] The sealant used in the battery case in the prior art, due to its poor temperature resistance and corrosion resistance, causes the battery case to crack at the seal under the working environment of 35-40°C, which cannot meet the use requirements of the battery

Abstract

The invention discloses an anticorrosion sealant. The anticorrosion sealant is prepared from, by weight, 52-72 parts of bisphenol epoxy resin, 20-32 parts of flexible epoxy resin, 12-18 parts of composite thinner, 5-10 parts of epoxy hardener, 1.5-3.5 parts of light calcium carbonate, 1.5-5.5 parts of synthetic resin tackifier, 1.2-2.5 parts of flexibilizer, 0.8-3.2 parts of antioxidant, 0.2-1.8 parts of corrosion inhibitor, 0.5-3.5 parts of wear-resistant agent, 0.6-2.2 parts of heat-resisting stabilizer and 1.2-4.5 parts of moisture scavenger. A preparation method includes the steps of firstly, evenly mixing and heating two types of resin; secondly, grinding, mixing and heating epoxy hardener, light calcium carbonate and synthetic resin tackifier; thirdly, mixing, heating and cooling the rest of additives and the mixtures of the first step and the second step. The prepared sealant has high corrosion resistance, heat resistance and adaptability, and the corrosion resistance of the prepared sealant is three to five times of corrosion resistance of sealant for a storage battery shell in the prior art.

Description

technical field [0001] The invention relates to a sealant, in particular to a corrosion-resistant sealant and a preparation method thereof. Background technique [0002] At present, the casing of sealed lead-acid batteries on the market often cracks. This is because during the long-term use of the battery, due to the high temperature, the electrolyte of the battery will flow out, which will affect the sealing quality of the sealing part of the battery casing. The battery casing causes corrosion, damages the battery casing, causes serious damage to the battery, and affects the service life of the battery casing. [0003] The sealant used in the battery case in the prior art, due to its poor temperature resistance and corrosion resistance, causes the battery case to crack at the seal under the working environment of 35-40°C, which cannot meet the use requirements of the battery. Contents of the invention [0004] The technical problem mainly solved by the present invention ...
