Preparation of Colloidal Antimony Pentoxide and Synergist Effect on Brominated Flame Retardant

Abstract:

Colloidal Antimony Pentoxide was prepared through a simple method based on reflux oxidization system. Detailed investigations about the effects of experimental parameters on the colloid stability and size distribution of the final products were carried out. The use of the combination of a brominated flame retardant 2,3-dibromo-succinic anhydride (DBrFR) as the flame-retarding agent and colloidal antimony pentoxide (APO) as the synergist to reduce the flammability of PET/cotton blend fabric was also studied. The BFR was effective in reducing the flammability of the blended fabric whereas APO enhances the effectiveness of DBrFR due to bromine–antimony synergism. The limiting oxygen index (LOI) value and the breaking strength retention of PET/ cotton fabric treated with DBrFR and APO were studied and the thermal behaviors of different treated fabrics were investigated via thermo gravimetric analysis (TGA).
