Insulation and sealing structure, the present invention are greatly improved cell sealing adhesive effect and are resistant to certain internal pressure, and electricity is effectively reduced
The Problem of Failure of pool insulation sealing bonding.
The technical solution adopted by the present invention to solve the technical problems is: a kind of for storeing the high pressure resistant insulation of formula battery
Sealing structure, including battery case and the battery core being arranged in inside battery case, filled with electrolysis between the battery case and battery core
Liquid is provided with pole column hole on the battery case, be respectively arranged in the pole column hole positive terminal being connected with battery core and
Negative terminal, the positive terminal and negative terminal are bonded on battery case by structural type adhesive and elastic binder.
It is a kind of for storeing the high pressure resistant insulation encapsulating method of formula battery that invention additionally discloses classes, comprising the following steps:
A), positive terminal and negative terminal are first passed through into solvent washing and drying treatment, then by battery case to gluing of surfaces
Mechanical grinding is carried out, is then cleaned with the rag for being soaked with solvent, by being done to gluing of surfaces in electric heating air blast on battery case
It is dried in dry case or dry with hair dryer；
B), the anti-sticking region of battery case, positive terminal and negative terminal is protected, at once in battery case, positive terminal and negative
Pole applies appropriate structural type adhesive to bonding plane, and battery core is packed into battery case, is fixed after assembly and with fixture, by adhesive
Condition of cure is solidified；
C), bonding interface region is subjected to mechanical grinding after solidifying, removes chalk dust removing；
D), bonding interface region is applied into elastic binder at once, is solidified by elastic adhesive condition of cure.
The beneficial effects of the present invention are:
1, the present invention is coated with elastic binder, elastic adhesive after being bonded with structural type adhesive at bonding interface
Agent can effectively cover issuable fine crack or cracking.
2, the present invention will carry out mechanical grinding to gluing of surfaces, increase surface roughness, increase adhesive strength.
3, the present invention will be cleaned with the rag for being soaked with solvent to gluing of surfaces, grease removal, increase adhesive strength.
4, components to be bonded are dried in electric drying oven with forced convection or are dried with hair dryer by the present invention, completely remove water
Vapour increases adhesive strength.
5, the present invention after bonding component surface processing after be bonded at once, prevent to gluing of surfaces again by dust,
The pollution such as steam, guarantees adhesive effect.
The present invention can effectively increase the adhesive strength of gluing of surfaces, avoid because of cell internal pressure, long-time aging, ring
Border condition or operating infulence and the adhesive layer fine crack or cracking generated, so that solution leakage or leakage be avoided to cause
The serious consequence of insulated enclosure failure, improves the reliability and safety of battery.
