Properties and Thermal Decomposition of SBS Flame Retarded with Phosphorus- and Nitrogen-Containing Flame Retardants

摘要

Flame retardant and mechanical properties of ammonium polyphosphate (APP), melamine phosphate (MP) and their combination with dipentaerythritol (DPER) in styrene-butadiene-styrene rubber (SBS) were studied. The results indicate that MP is more effective in raising limiting oxygen index (LOI) in SBS than APP. When DPER is incorporated into the SBS/APP and SBS/MP composites, a great improvement in flame retardancy of the composites is observed. Moreover, thermal decomposition and mechanical properties of the SBS composites were investigated.
