FLAME-RETARDANT POLYPROPYLENE COMPOSITION HAVING EXCELLENT CORROSION-PROOF |
摘要 |
PURPOSE: A flame-retardant polypropylene composition is provided to improve flame retardancy by the addition of a halogen capture agent, and to prevent corrosion of metals due to harmful gas generated during the processing of a resin. CONSTITUTION: A polypropylene resin composition includes 40.0-98.0 wt% of a polypropylene resin; 1.0-30.0 wt% of a bromine-based flame retardant; 0.5-20.0 wt% of an inorganic flame retardant; and 0.5-10.0 wt% of a halogen capture agent. The polypropylene includes a propylene homopolymer and one or more copolymers of propylene-alpha-olefin copolymers (C4-18). The melt flow index of the polypropylene is 0.1-100 g/10 minutes (230°C/2.16kg), and an isotactic pentad fraction by C-NMR method is 96% or more.
