The Flame Retardant Synergism between Cobalt Complexes and Ammonium Polyphosphate in Cottonwood
Keyword(s):
The synergistic flame-retarded effects of a similar molecular sieve [Co5(OH)2(tca)2(ina)2 (H2O)2]•4H2O(Co5) and ammonium polyphosphate(APP) on cottonwood was studied. Compared with APP added individually, when the addition of Co5 was 1.7%, THR reduced 18.3% and the mass loss reduced 7.7%. The TGA showed that the processes of losing solvent water, coordinated water, tricarballylic acid and isonicotinic acid ligands can inhibit burning and lower the weightlessness rate. The flame retardancy of APP/Co5 was superior to that used APP individually, Co5 showed good synergistic flame-retarded effects.
