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 a methacrylic acid ethylene glycol diester high-viscosity accumulator sealant based on epoxy resin and a preparation method thereof. The accumulator sealant comprises a component A and a component B, wherein the component A comprises dibutyl tin diacetate, PE (polyethylene), tert-butyl hydroperoxide and chloroprene rubber; the component B comprises epoxy resin, methacrylic acid ethylene glycol diester, chlorosulfonated polyethylene, acetylacetone nickel, dibutyl sebacate, a defaming agent and paraffin. Through the utilization of the heat generated between the sealants during use, the curing speed and the adhesion efficiency of the combined sealant are improved; heat resistance, acid resistance and adhesion performance of the sealant are superior to those of other types of accumulator sealants; the ratio is not required to be strictly controlled when the sealant is prepared; the sealant is not required to be heated and cured; the production process of accumulators is simplified; the production cost of the accumulators is reduced.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to an epoxy resin-based ethylene glycol diester methacrylate strong viscous battery sealant and a production method that can seal 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...
