Abstract

Polypropylene is widely used as a component material for various industrial machines and devices. Thermoplastic polymer materials are crystalline polymers that have a low friction coefficient and strong characteristics, so they are used as materials for gears, plumbing parts, automobile parts, and toys. Ultra-high molecular weight polypropylene (UHMWPP), a polypropylene with a molecular weight of over 1 million, is a high-stiffness, high-impact resistant material that has higher impact strength than general PP and is currently friction resistance, which is used not only for interior materials but also for rubber materials. Research is underway to apply it to sealing products.


폴리프로필렌은 각종 산업용 기계 및 장치의 부품 소재로 널리 사용되며, 열가소성 고분자 소재는 결정성 고분자로 마찰계수가 낮고 특성이 강하여 기어, 배관부품, 자동차 부품, 장난감 등의 소재로 사용된다. Ultra-high molecular weight polypropylene(UHMWPP)는 분자량 100만 이상의 폴리프로필렌으로 일반 폴리프로필렌에 비해 충격강도가 높은 고강성, 고충격 소재로 내마모성이 뛰어나 자동차 내장재뿐만 아니라 고무 대체가 가능하다. 본 연구에서는 UHMWPP의 유리섬유 및 무기충전제 복합재료의 물성 및 내마찰특성을 폴리프로필렌과 비교 확인하고, 왕복마찰 시험장치를 이용하여 연구를 진행하였다.


Keywords: ultra-high molecular weight polypropylene, high strength, low density, polymer composite.
