Document Type and Number:
WIPO Patent Application WO/2022/139176
Kind Code:
A1
Abstract:
A thermoplastic resin composition of the present invention comprises: approximately 100 parts by weight of a polyolefin resin comprising a polypropylene resin and/or an ethylene-propylene block copolymer; approximately 30-60 parts by weight of a phosphorus/nitrogen-based flame retardant; approximately 0.2-12 parts by weight of a maleic anhydride-modified olefin-based polymer; approximately 5-45 parts by weight of talc; and approximately 0.1-15 parts by weight of expanded graphite having an expansion start temperature of approximately 220°C or higher, wherein the weight ratio of the talc and the expanded graphite is approximately 1:0.003 to 1:0.3. The thermoplastic resin composition has excellent flame retardancy, heat resistance, rigidity, formability, physical property balance thereof, and the like.
