| titleOfInvention | Polypropylene resin composition excellent in impact resistance |
| abstract | The present invention relates to a polypropylene resin composition having excellent impact resistance, and more particularly, to a polypropylene resin composition having various melt indices capable of extrusion and injection molding while being excellent in impact resistance, heat resistance and rigidity by crosslinking a predetermined amount of polypropylene. It is about.n n n In the polypropylene resin composition according to the present invention, a polypropylene resin having a high weight average molecular weight and a polypropylene resin having a high content of α-olefin and excellent fluidity are mixed at a predetermined ratio. Reaction extrusion with the addition of more than one organic peroxide has a certain level of crosslinking degree, which increases impact resistance, heat resistance and rigidity, and various fluidity that can be molded from low melt index extrusion products to high melt index injection products. Haven n n In addition, the polypropylene resin composition having excellent impact resistance of the present invention can be used in injection and extrusion products requiring impact because the resin itself has excellent impact strength and rigidity without using an impact modifier such as rubber. In addition, it is possible to contribute to cost reduction by reducing the rubber content of the high impact polypropylene-based / rubber compounding material with a lot of rubber content. |
