Problems solved by technology

[0002] The amine curing agent of the existing battery sealing glue is easy to crystallize and the usable time of the glue (the time for the glue to double its viscosity at a certain temperature) is short. The usable time reflects the reaction speed of the glue and determines the customer. The length of time the glue can be used and operated after the glue is formulated, and the crystallization of the curing agent within the shelf life after it is produced makes the customer unable to use the product

Abstract

The invention relates to storage battery sealing gum and a preparation method of the storage battery sealing gum. The storage battery sealing gum is prepared from the following components: (1) a resin part and (2) a curing agent part in ratio of 100:(20-40), wherein the resin part comprises 80-95 parts of bisphenol A epoxy resin, 5-15 parts of an activated thinner and 0-3 parts of a defoaming agent, and the curing agent part comprises 40-60 parts of aliphatic series polyamine, 10-30 parts of alicyclic amine, and 20-40 parts of an activated thinner. The preparation method comprises the following steps: (1) uniformly mixing the raw materials of the resin part; (2) uniformly mixing the alicyclic amine and 60-80% of aliphatic series polyamine of the curing agent part, dropping in 50-70% of activated thinner of the curing agent part while stirring, heating, adding the remaining aliphatic series polyamine, dropping in the remaining activated thinner and heating; and (3) uniformly mixing the products in the step (1) and the step (2). The usable time of the sealing gum is prolonged and the crystallinity of the curing agent is improved by proper proportion of raw materials and improved production process of the curing agent.

Description

technical field [0001] The invention relates to a storage battery sealant and a preparation method thereof. Background technique [0002] The amine curing agent of the existing battery sealing glue is easy to crystallize and the usable time of the glue (the time for the glue to double its viscosity at a certain temperature) is short. The usable time reflects the reaction speed of the glue and determines the customer. The length of time the glue can be used and operated after the glue is formulated, and the crystallization of the curing agent within the shelf life after production makes the customer unable to use the product. For battery sealants, the above-mentioned problems are likely to occur under the improper proportion of each raw material in the curing agent and the original production process of the curing agent. [0003] The preparation process of the curing agent commonly used in the prior art is as follows: add the aliphatic polyamine into the reaction kettle at r...
