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 di-ester strong-viscidity storage battery sealant. The sealant is prepared from a component A and a component B, wherein the component A is prepared from ketimine, PC-polycarbonate, methyl ethyl ketone peroxide and chloroprene rubber; the component B is prepared from epoxy resin, hydroxypropyl methacrylate, acrylic rubber, tetramethylthiourea, dibutyl phthalate, a defoaming agent and paraffin. Heat generated mutually when the sealant is in use is utilized, the curing speed and the bonding efficiency of an assembly adhesive are improved, the heat resistance, the acid resistance and the adhesive property of the sealant are better than those of other kinds of storage battery sealants, during manufacturing and sealant preparation, the proportion does not need to be strictly controlled, heating and curing are not needed, the storage battery production process is simplified, and the production cost of storage batteries is lowered.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to an epoxy resin-based double-fat strong-adhesive 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 lead-acid bat...
