Abstract

Recently, efforts are being made to develop composite materials that can replace aluminum materials for interior and exterior parts with excellent impact resistance and low specific gravity, and efforts are also being made to develop composite materials using ultra-high molecular weight polypropylene to improve properties such as lightness, heat resistance, formability, wear resistance, and impact resistance. Therefore, ultra-high molecular weight polypropylene is a unique heat transfer polymer with excellent performance, making it difficult to continuously process ultra-high molecular weight polypropylene without using processing aids due to its ultra-high molecular weight rheological behavior.
In this study, we conducted a process study on how to manufacture polypropylene resin with an average diameter of 0.1 to 200 mm into a pellet form that can be extruded and injected, and it is expected to be helpful in understanding ultra-high molecular weight polypropylene.


최근 내충격성이 우수하고 비중이 낮은 내외장 부품용 알루미늄 소재를 대체할 수 있는 복합소재 개발에 노력을 하고 있으며 경량성, 내열성, 성형성, 내마모성, 내충격성 등의 물성을 향상시키기 위해 초고분자량 폴리프로필렌를 이용한 복합재료 개발에도 노력을 하고 있다. 따라서, 초고분자량 폴리프로필렌은 탁월한 성능을 지닌 독특한 열가소성 폴리머로 초고분자량 유변학적 거동으로 인해 가공 보조제를 사용하지 않고 초고분자량 폴리프로필렌을 연속적으로 가공하는 것은 어렵다. 본 연구에서는 평균직경이 0.1 내지 200 mm인 폴리프로필렌 수지를 압출 및 사출이 가능한 펠릿형태로 제조하는 방법에 대한 공정 연구에 과한 것으로 초고분자량 폴리프로필렌을 이해하는데 도움이 될 것으로 기대된다.
