Abstract

The invention provides an aluminum plastic film and in particular relates to an aluminum plastic film (a lithium battery package material) specially used for a lithium battery. An outer layer, a first adhesive layer, a first priming coat layer, a middle layer, a second priming coat layer, a second adhesive layer and a bottom layer are sequentially arranged from top to bottom; the first adhesive layer is used for combining the inner surface of the outer layer and the middle layer; the bottom layer is positioned below the inner surface of the middle layer; the second adhesive layer is used for combining the inner surface of the middle layer and the bottom layer; the first priming coat layer and the second priming coat layer are functional treatment layers. Salts in organic electrolyte of the lithium battery can react with steam to generate hydrogen fluoride which is extremely corrosive, so that the treatment of the functional treatment layers at a preset position in the aluminum plastic film serves as protection for the middle layer and structural treatment of barriers; the overall structure is specially used for materials applied to package of the lithium battery.

Description

【Technical field】

[0001] The present invention is related to the interlayer lamination (Lamination) technology and the functional treatment layer technology (Fundation Treatment) of the multi-layer composite film, especially the first primer with the functions of high moisture barrier and ultra-high gas barrier (organic solvent) layer and the second primer layer (Fundation Coating) to protect the middle layer, and use high temperature resistant and heat-curable special first adhesive layer (agent) and second adhesive layer (agent) (adhesive) to isolate ( Prevent penetration) electrolyte in lithium battery (lithium hexafluorophosphate LiPF 6 +organic solvent+additive), which releases highly corrosive hydrogen fluoride (HF) due to heat or moisture interference, and is a multi-layered product with anti-corrosion, moisture resistance, gas barrier, heat resistance, cold resistance and formability Composite technology, a kind of aluminum-plastic film specially used for lithium batt...
