오일함침 나일론 6의 합성 및 마찰특성

Synthesis and Friction Properties of Oil-impregnated Nylon 6

정대원, 강석춘

초록

ε-caprolactam의 음이온 중합반응을 미네랄 오일의 존재하에서 수행하여 오일함침 나일론 6을 합성하였다. 8 phr 미만의 오일이 첨가되었을 때에는 중합반응속도 및 생성물의 분자량에 큰 변화가 없었다. 오일의 첨가에 의해서 생성물의 신율 및 충격강도는 향상되었으며, 표면경도와 인장강도는 저하되었다. 오일함량이 6 phr인 나일론에서 마찰계수는 최소값을 나타내었으며, 이때의 마찰계수값은 오일이 첨가되지 않은 나일론의 32%에 지나지 않았다.

Oil-impregnated nylons were synthesized by anionic polymerization of ε-caprolactam in the presence of mineral oils. Reaction rate and molecular weight of the product were not significantly affected by the addition of oils less than 8 phr. Physical properties such as elongation and notched impact strength were improved by the addition of oil, on the other hand hardness and tensile stress at break were slightly decreased. Oil-impregnated nylon with an oil content of 6 phr showed a minimum friction coefficient, which is only 32% compared to a friction coefficient of nylon 6 without oil.
