ABSTRACT:
A process for producing asphalt-blended polyurethane foams which comprises introducing starting foaming materials for polyurethane foams containing a polyoxyalkylene polyol and an organic isocyanate either as respective individual ingredients or as a prepolymer into an agitation mixing chamber of a foaming apparatus, while introducing a previously heated and melted asphalt into the agitation mixing chamber of the foaming apparatus, mixing the starting foaming material for the polyurethane foams and the heated and melted asphalt and then foaming them. Asphalt-blended polyurethane foams can be obtained simply and efficiently and they are excellent in general physical properties, sound/vibration characteristics and are suitable as sealing materials and sound-proofing or vibration-damping materials.
