New high-strength, cooking-resistant polyurethane adhesive

Posted on

The present invention relates to the preparation of aluminum plastic composite food packaging films using a compound containing a plurality of aromatic ring rigid segments as a starter or a chain extender such as maleic anhydride, maleated rosin and modified bisphenol A epoxy resin. Preparation of two-component cooking-resistant polyurethane adhesives for building decoration materials, the main component of which is the A component: Polyester polyol (with a molecular weight of 1500-5000) is chain-extending into isocyanate-polyurethane polyol (The relative molecular mass is 3000 to 10 000), Part B: Polyisocyanate.
The A and B components are mixed in a certain proportion and evenly coated on the surface of plastic film, plastic sheet or aluminum foil, and then compounded. The composite film or composite sheet prepared by using the adhesive does not peel off automatically when the plastic film or the plastic sheet and the aluminum foil are liquefied under 0.11 MPa boiling water, and has high peel strength.
