STORAGE-STABLE HEAT-CURABLE GRANULAR MATERIAL MIXTURE

摘要

The invention relates to a heat-curable granular material mixture, which comprises a first granular material (G1) and a second, epoxide-free granular material (G2). The second, epoxide-free granular material (G2) comprises at least one heat-activated accelerator (B) for the curing of solid epoxide resin (A) having dicyandiamide, and at least one thermoplastic (T) that is solid at room temperature and that has a softening point between 70°C and 140°C measured according to the ring-and-ball method as per DIN EN 1238. Furthermore, the heat-curable granular material mixture comprises dicyandiamide, which is part of the first granular material (G1) and/or the second granular material (G2), and at least one heat-activated blowing agent (TM), which is part of the first granular material (G1) and/or the second granular material (G2) independently of each other. The heat-curable granular material mixture is characterized by extraordinary storage stability and good foaming behavior.
