Summary: | A waste polypropylene resin composition is provided to improve impact resistance and flowability, to allow it to be formed even in case of a small thickness and to lower a manufacturing cost by recycling the wasted bumper of automobiles. A waste polypropylene resin composition comprises 30-40 wt% of a waste polypropylene resin containing 40-50 wt% of glass fiber; 20-40 wt% of a waste thermoplastic olefin-based resin; 10-30 wt% of a high crystalline polypropylene resin; 3-9 wt% of a plastomer; 5-10 wt% of a co-polypropylene resin; and 12-25 wt% of glass monofilament. Preferably the waste polypropylene resin has a flow index of 30-80 g/10 min; the waste thermoplastic olefin-based resin has an impact strength of 35-45 kg.cm/cm and a flow index of 10-20 g/10 min; and the high crystalline polypropylene resin has an impact strength of 5-10 kg.cm/cm and a flow index of 100-250 g/10 min. |
