The content of type epoxy resin is the 3~30% of adhesive for polyurethane solid content, and the chemical formula of the bisphenol A type epoxy resin is such as
Under：
Wherein n value is 0.2~10；The adhesive for polyurethane includes host and curing agent, and the host is gathered for terminal hydroxy group
Ester component, curing agent are terminal isocyanate group component, and the ratio of the host and the curing agent is 9:1~9:2.
Such scheme is visible, one kind that bisphenol A type epoxy resin therein includes but is not limited in E54, E44, E20, E12
Or it is a variety of, due to containing secondary hydroxyl in bisphenol A type epoxy resin, it is directly added into adhesive for polyurethane as polyalcohol and contains terminal hydroxy group
In polyester components, solidify with isocyanate component, obtain the polyurethane network polymer of Graft Epoxy Resin, this is greatly enhanced
The peel strength of adhesive for polyurethane.
Plastic-aluminum combined carry out plastic-aluminum combined method using above-mentioned with bonding agent and comprise the following steps：
（1）Get each component ready in proportion；
（2）Bisphenol A type epoxy resin is dissolved and is added in adhesive for polyurethane host and mixes；
（3）After well mixed, then mix with adhesive for polyurethane curing agent；
（4）Combined Processing is carried out to aluminium foil and plastic film material using dry process, obtains compound aluminum-plastic composite membrane.
Such scheme is visible, and the inventive method technique is simple, and cost is cheap, utilizes the above-mentioned plastic-aluminum with high-peeling strength
Compound when carrying out plastic-aluminum combined with bonding agent, its peel strength is fabulous.
Further, the step（4）In, the spread of dry process is 3~5g/m2.As can be seen here, the inventive method
Technique is simple, and glue consumption is small, reduces cost of manufacture.
Yet further, the plastic film material includes but is not limited to nylon, polyester film or the stacked film of the two.Thus may be used
See, using the plastic-aluminum combined making that can be used for a variety of plastic film materials with bonding agent of the present invention, its wide adaptation range, increase it
Application.
