Disclosed are a polyolefin-based flame retardant resin composition and a molded product. The present invention relates to a polyolefin-based flame retardant resin composition satisfying flame retardancy (particularly, UL94V V-0, V-1, and V-2 grades, an auto ignition property of 15 seconds or less, and eco-friendly flame retardancy), improved extrusion properties, a melt index, tensile elongation, or appearance quality required in use of extruded tube molds and the like for insulation and wiring in electrical and electronic products, and vehicles using a particular phosphate-based flame retardant, and a molded product manufactured from the composition are disclosed.
A polyolefin-based flame retardant resin composition comprising a polyolefin resin and a phosphate-based flame retardant, wherein the resin composition comprises 50 to 80 wt % of the polyolefin resin and 0.1 to 5 wt % of a surface-modified fluorine resin powder, wherein the surface-modified fluorine resin powder has a weight-average molecular weight of 100,000 g/mol or more and is prepared by extruding 0.1 to 90 wt % of surface-modified polytetrafluoroethylene having an average particle diameter of 10 μm or less and 10 to 99.9 wt % of a polypropylene resin having a viscosity of 500 to 1400 ml/g, and the phosphate-based flame retardant comprising 20 to 40 wt % of a solid phase phosphate flame retardant and 0.1 to 15 wt % of a liquid-type phosphate ester flame retardant, based on 100 wt % in total of ingredients constituting the composition.
