PURPOSE: A producing method of a polypropylene-ethylene propylene rubber composite is provided to offer the excellent IMPACT STRENGTH and Rheological property of the composite to users. CONSTITUTION: A producing method of a polypropylene-ethylene propylene rubber composite comprises the following steps: mixing polypropylene and ethylene propylene rubber; and performing a melting process with the mixture for more than 2 times. The ethylene propylene rubber is selected from ethylene propylene monomer rubber, ethylene propylene diene monomer rubber, or their mixture. The melting process is performed by using a same direction twin screw extruder. |
