초록

천연고무 라텍스(NRL)와 세틸메타 크릴레이트가 그라프트된 라텍스(MGL)를 각종 첨가제와 혼합하여 dipping공정으로 가황된 NR 및 블렌드 필름을 제조하였다. NR 필름 제조의 최적조건을 규명하기 위하여 숙성시간에 따른 팽윤도, 인장강도 및 110℃에서 가황시간의 변화에 따른 기계적 특성을 비교하였다. 필름 표면의 구조 및 미끄럼성을 조사하기 위하여 접촉각 및 정·동마찰계수를 측정한 결과, 접촉각은 MGL의 블렌드 비율이 증가할수록 감소하였고, 정 및 동마찰계수는 NR 필름에 비하여 NR/MG과 NR-d-MG 필름이 현저히 감소하여 표면 미끄럼성이 향상됨을 알 수 있었다.

The vulcanized NR and blend films were prepared with mixing of natural rubber latex (NRL) and methyl methacrylated grafted latex(MGL) with various additives by dipping process. It was investigated the basic properties of vulcanized NR films that is optimum condition of the mature time, swelling degree, cure time at 110℃, and measured the mechanical properties of tensile strength and elongation of its condition. In order to identify the surface structure and the slip properties of blend films contact angles and static and kinetic friction coefficient were measured. Contact angles were decreased with increment of blend ratio of MGL, and static and kinetic friction coefficient were decreased rapidly for the NR/MG and NR-d-MG films than for the NR films. From the results, NR/MG and NR-d-MG films has slip's reinforcement in skin contact surface with increased of blend ratio of MGL.
