摘要： Disclosed herein are a process for producing an epoxy adhesive auxiliary which is a liquid reclaimed from rigid polyurethane foam and an epoxy adhesive which contains the auxiliary. The epoxy adhesive auxiliary can be produced, without requiring any special apparatus for purification, by incorporating rigid polyurethane foam (200 g) in powder form (5-10 mm in size) with glycol such as polyethylene glycol (100 g) and amino alcohol such as 2-aminoethanol (5 g), and heating them at 150.degree.-280.degree. C., thereby chemically decomposing the rigid polyurethane foam into a viscous liquid. This reclaimed liquid (50-300 g) is incorporated as such into an epoxy resin adhesive base such as bisphenol A-type epoxy resin (100 g), containing optional diethylamine (6-8 g). The resulting epoxy resin adhesive is superior in tensile shear bond strength.
