FIRE-RETARDANT POLYPROPYLENE RESIN COMPOSITION COMPRISING POLYPROPYLENE RESIN, OLEFIN-BASED OLIGOMER AND ORGANIZED LAMELLAR SILICATE

摘要

PURPOSE: A fire-retardant polypropylene resin composition is provided, which improves fire-retardancy, processability, and mechanical properties, therefore can be used for coating fabrics, coating and insulating electric wires, structures, cases of electronic products, and plastic injection, extrusion goods. CONSTITUTION: The fire-retardant polypropylene resin composition contains: 100pts.wt. of a matrix comprising 70-99pts.wt. of a polypropylene resin and 1-30pts.wt. of an olefin-based oligomer containing at least two hydroxy groups, wherein the polypropylene resin has a melt index of 0.5-80g/10min and is a crystalline isotactic propylene homopolymer, an ethylene-propylene block or random copolymer, or a mixture thereof; 10-40pts.wt. of a halogen-based fire-retardant agent; 0.5-10pts.wt. of an organized lamellar silicate as a fire-retardant agent.
