PROCESS FOR PRODUCING A COMPOSITE FOAM FROM FOAM FLAKES, A COMPOSITE FOAM AND USES THEREOF

摘要

For manufacturing a composite foam, having acoustic properties, foam flakes (8) of differing sizes, differing origins, and/or differing material compositions are wetted with a small quantity of a polyurethane dispersion binding agent. The mixture is subsequently combined to a molded part (1) or to continuous web and under the effect of hot (water) steam or microwave energy is cured and subsequently dried. The composite foam can be used for sound insulation purposes in vehicles and in general machinery construction, and also in building construction.
