Problems solved by technology

[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 battery shell when opening the sealing cover is an urgent problem to be solved

Abstract

The invention discloses an epoxy-resin-based propyl ester strong-viscidity storage battery sealant and a manufacturing method. The sealant is manufactured from a component A and a component B, wherein the component A is prepared from N-beta hydroxyethyl ethylenediamine, PC-polycarbonate, benzoyl peroxide and acrylic rubber; the component B is prepared from epoxy resin, hydroxypropyl methacrylate, chloroprene rubber, acetylacetone, dimethyl polydimethylsiloxane, 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 industry, in particular to an epoxy resin-based propyl ester 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 battery...
