Description
Technical field
The present invention relates to a kind of adhesive, more particularly to a kind of aluminum-plastic membrane used for packaging lithium battery corrosion resistant type adhesive.
Background technology
Lithium ion battery is since its is light-weight, capacity is big, has extended cycle life and the advantage such as memory-less effect, in digital electricity
Subdomains extensive use, it is in recent years, even more fast-developing in emerging fields such as new-energy automobile, energy storage.Traditional lithium battery uses
Aluminum hull, the rigid material such as box hat packaging, in addition to lightweight problem, there is also pressure to cross the security risks such as huge explosion.For
A series of problems existing for lithium battery mental package, a kind of new aluminum-plastic composite membrane packaging material come into being.The packaging material
Generally formed by trilamellar membrane Material cladding, be protective layer, aluminium foil layer, corrosion-resistant hot sealing layer successively from outside to inside, usual protective layer
It is the nylon membrane of biaxial tension（BOPA films）, anti-corrosion layer be cast polypropylene film（CPP films）.The electrolyte of lithium battery includes more
Kind organic solvent and lithium salts, lithium salts, which meets water, can produce the hydrofluoric acid of severe corrosive and other gases rapidly, and hydrofluoric acid is once with molten
CPP films are permeated in agent, will corrode CPP and to the tack coat between aluminium foil, and destroy aluminium foil surface, inner membrance is separated with aluminium foil,
The problems such as causing lithium battery expansion, leakage failure.
At present, in industry, the bonding mode of aluminium foil and outer layer nylon membrane, is dry-lamination process.But aluminium foil and CPP
The bonding mode of film, mainly there is two kinds.One kind is that hot pressing is compound, i.e., binder resin is extruded lamination in aluminium foil table using extruder
Face, then hot repressing bond CPP films.Another is aluminium foil surface coating conventional polyurethanes or acrylate adhesive, then is dried
Dry solvent progress dry type is compound, and part of the manufacturer is also coated with Japanese import adhesive.Hot pressing combination process uses improved polyalkene tree
