초록

ENR/CR 블렌드 가류물에 대한 기계물성을 측정하였다. 열노화에 따라 경도는 증가하였으나 탄성율(300%), 인장강도 및 파단신율은 현저히 감소하였다. 기름노화에 따라 인장강도 및 파단신율과 아울러 경도도 감소하였으며, 경도감소는 체적팽창으로 설명하였다.

The mechanical properties of ENR(epoxidized natural rubber) blends with CR(chloroprene rubber) were measured for both unaged and aged vulcanizates. Upon heat aging, hardness increased, and tensile strength, modulus, and elongation at break decreased. Tensile strength and elongation at break also decreased upon aging in oil, hardness decreased due to the oil swell into the rubber.
