Problems solved by technology

[0003]With the increasing market demand for batteries year by year, more and more attention has been paid to the disposal of used batteries and the maintenance of batteries, and the key to battery maintenance is to open the sealing cover Can not damage the battery shell, if some existing sealants have high bonding strength, the battery shell will be damaged because the sealant is difficult to peel off when the sealing cover is opened, and the high bonding strength that is easy to peel off is relatively low, how to ensure Good bonding strength and no damage to the battery casing when the sealing cover is opened is a difficult problem to be solved urgently

Abstract

The invention discloses an epoxy resin based high-adhesion butyl acrylate sealant for storage batteries and a manufacturing method of the epoxy resin based high-adhesion butyl acrylate sealant. The epoxy resin based high-adhesion butyl acrylate sealant comprises a component A and a component B; the component A comprises N-beta hydroxyethylenediamine, PVC (polyvinyl chloride), benzoyl peroxide and chlorosulfonated polyethylene; the component B comprises epoxy resin, butyl acrylate, chloroprene rubber, nickel acetylacetonate, dioctyl phthalate, an antifoaming agent and paraffin. Curing speed and adhesion efficiency of the sealant are increased through heat generated in use of the sealant, and heat resistance, acid resistance and adhesion performance of the sealant are superior to those of other types of sealants for the storage batteries. In addition, strict control of proportion in mixing of the two components is not required, heat curing is avoided, and accordingly storage battery production process is simplified, and storage battery production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an epoxy resin-based butyl acrylate strong viscous battery sealant and a production method for sealing batteries. Background technique [0002] With the rapid development of China's battery industry, the performance of the battery sealant, which is directly related to the quality of the battery, has attracted more and more attention from experts in the industry and various industries at home and abroad. The main components of sealing adhesives widely used in the battery industry are Amine or modified amine-cured epoxy system or polyurethane system adhesives, epoxy system adhesives require a long curing time at room temperature, sometimes even heat curing, and are relatively brittle, so this system is used as lead The sealing materials for poles and tank covers of acid batteries are still unsatisfactory; polyurethane adhesives can meet the requirements of lead-acid batte...
