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 glycol diester strong viscous storage battery sealant based on epoxy resin and a preparation method thereof. The sealant includes a component A and a component B; the component A consists of dibutyltin dilaurate, PC-polycarbonate, tert-butyl hydroperoxide and chloroprene rubber; the component B consists of epoxy resin, methacrylic acid glycol diester, acrylic rubber, N'-dimethyl urea, propylene carbonate, a defoaming agent and wax. The mutual heat generated between usage increases the curing rate and bonding efficiency of the combined adhesive; the sealant has heat resistance, acid resistance and adhesion better than those of other storage battery sealants. In preparation, the ratio of rubbers does not need to be strictly controlled, and heating and curing are not required, so as to simplify the production process of the storage battery and reduce the production cost of the storage battery.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an epoxy resin-based ethylene glycol diester strong viscous battery sealant and a production method thereof which can seal batteries. Background technique [0002] With the rapid development of my country'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 requirem...
