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 accumulator seal gum, which is characterized in that: it comprises component A and B, and the weight proportion between A and B is 4: 1; A comprises epoxy resin, diluting agent and / or solvent; B comprises curing agent and plasticizing agent. Said epoxy resin is bisphenol a epoxy resin or mixture of bisphenol a epoxy resin and novolac epoxy. The flowability of seal gum is pretty good, and it will flow levelly automatically instantly after injection in plastic groove, which greatly increases the working efficiency for aritifical sealing, and the stretching and cutting strength is far better than the country standard of 3 Mpa.

Description

technical field [0001] The invention relates to a sealing adhesive, in particular to an adhesive used for sealing and bonding lead-acid storage batteries. Background technique [0002] Lead-acid battery is an industrial product with a wide range of uses and a huge demand. During the production process, the connection and wiring parts of the battery tank cover are generally sealed with adhesives to block the acid. [0003] With the increasing demand of the battery market, more and more attention is paid to the treatment of waste batteries and the maintenance of batteries. The key to battery maintenance is to open the sealing cover without damaging the battery shell. If some existing sealants are sticky If the bonding strength is high, when the sealing cover is opened, the battery shell will be damaged because the sealant is difficult to peel off, and the bonding strength that is easy to peel off is relatively low. How to ensure good bonding strength without damaging the batte...
