AI Technical Summary

Technical Problem

In the partition between multiple heating elements, when the outer packaging material of the partition is a laminate consisting of a metal layer and a thermoplastic resin layer bonded together by an adhesive layer, the adhesive strength is easily reduced by the contents such as coolant.

Method used

An outer packaging material for a partition component is adopted, which is composed of at least a metal layer, an adhesive layer and a thermoplastic resin layer in sequence, wherein the adhesive layer is formed by curing a polyolefin adhesive to improve the adhesion between the metal layer and the thermoplastic resin layer.

Benefits of technology

It effectively suppresses the decrease in adhesion between the metal layer and the thermoplastic resin layer, improves the tightness and stability of the partition components, prevents the heating element from shifting or being compressed, and ensures cooling efficiency.

Abstract

This invention provides an outer packaging material for a separator component, comprising a laminate having at least a metal layer, an adhesive layer, and a heat-melting resin layer in sequence, wherein the decrease in adhesive strength between the metal layer and the heat-melting resin layer of the outer packaging material is suppressed. The aforementioned outer packaging material for a separator component is used as a separator component disposed between multiple heating elements. The outer packaging material for the separator component is composed of a laminate having at least a metal layer, an adhesive layer, and a heat-melting resin layer in sequence, wherein the adhesive layer is formed from a cured product of a polyolefin-based adhesive.
