사출성형 시 흐름자국이 생기지 않는 흐름성이 향상된 PP(Polypropylene) 복합재료를 제조하기 위한 연구를 진행하였다. PP는 분자량 분포와 용융지수(MI)가 다른 4종류의 PP를 사용하였으며, PP, 탈크, 고무와 약간의 첨가제로 구성된 PP컴파운드의 유변학적 특성은 Spiral Flow(SF), MI, 전단점도를 측정함으로써 평가하였다. 분자량 분포가 넓은 PP를 사용한 경우 MI가 상대적으로 낮다 하더라도 SF는 MI가 높은 PP보다 높게 관찰되는 경우도 있었다. 사출성형시 표면에 흐름자국이 발생하지 않도록 하기 위해서는 분자량 분포가 넓은 PP를 사용하는 것이 바람직함을 확인하였다.

Our objective is to increase the flowability of Polypropylene(PP) compounds and achieve flow mark free surface in injection molded specimen. We have investigated flowabilities of PP compounds which were composed of PP, rubber, talc, and trace amount of additives. Flowability measurement was performed with four types PPs of which molecular weight distributions(MWD) and melt indexes(MI) were different. Rheological properties of the PP compounding materials, such as spiral flow(SF) length, MI, and shear viscosity, were evaluated. When PP with the broad MWD was used, there were remarkable cases where the spiral flow length of low MI PP compound was longer than that of higher MI PP compound. The PP compound having low MI but broad MWD PP has more flowability than the compound with only high MI.
