DI(AMINOGUANIDIUM) 4,4',5,5'-TETRANITRO-2,2'-BIIMIDAZOLE, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a method for stabilizing unstable hydrogen of 4,4 ', 5,5'-tetraenitro-2,2'-biimidazole, which is promising as a desensitizing high-performance molecular blowing agent, with aminoguanidine to form di (aminoguanidium) ', 5,5'-tetranitro-2,2'-bimidazole to reduce the hygroscopicity of 4,4', 5,5'-tetranitro-2,2'-biimidazole , And a method for improving performance and dullness.
