Process for continuously producing at high speeds a foam polyurethane resin laminate

Abstract

Abstract THERMOSET FOAMS AND FOAM LAMINATES ARE PREPARED BY APPLYING A COATING OF A FIRST REACTANT ONTO A PLURALITY OF SUBSTRATES, PASSING THE SUBSTRATES THROUGH A PAIR OF NIP ROLLS, APPLYING THE SECOND REACTANT AT THE INTERFACE OF THE PLURALITY OF SUBSTRATES AND ADJUSTING THE PRESSURE BETWEEN THE PAIR OF NIP ROLLS SUCH THAT A FILLET OF THE FIRST AND SECOND REACTANTS IF FORMED AT THE INTERFACE OF THE PAIR OF SUBSTRATES, PASSING THE SUBSTRATES CONTAINING THE EXPANDING MIXTURE OF REACTANTS THROUGH A SIZING DEVICE WHEREIN EXPANSION BETWEEN THE SUBSTRATES IS COMPLETED THEREBY PRODUCING A THERMOSET FOAM LAMINATE.
