NON-HALOGEN FLAME-RETARDANT POLYPROPYLENE RESIN COMPOSITION HAVING HIGH RIGIDITY

摘要

PURPOSE: A flame-retardant polypropylene resin composition is provided to reduce the content of a flame retardant by adding non-halogen organic flame retardants, to improve heat resistance and rigidity by adding filler such as glass fiber, and to secure dimensional stability. CONSTITUTION: A non-halogen flame-retardant polypropylene resin composition comprises 10.0~96.9 weight% poly propylene resin, 1.0~40.0 weight% phosphate-based flame retardant, 1.0~10.0 weight% flame-retarding aid, 1.0~30.0 weight% inorganic filler, 0.1~10.0 weight% modified polypropylene as a compatibilizer, or 0.1~10.0 weight% organic silane compound. The phosphate-based flame retardant is ammonium polyphosphate or pre-treated compound thereof.
