FAST CURING EPOXY SYSTEM FOR PRODUCING RIGID FOAM AND USE OF THE FOAM IN COMPOSITES OR AS INSULATION MATERIAL

摘要

The present invention relates to a novel method for manufacturing rigid epoxy foams. Furthermore the present invention relates to materials, especially novel two-component epoxy systems that are used to conduct this method. This novel process is characterised in that an epoxy resin is mixed with a blowing agent, especially an encapsulated blowing agent, and afterwards with an ionic liquid. Surprisingly the reaction, including foaming, starts at room temperature after a short time like after only 2 to 3 minutes. In summary, the present invention comprises a two-component foam-in-place structural material and a process for producing a rigid epoxy foam.
