摘要

考察了三元乙丙橡胶(EPDM)产品的物理化学性能(挥发分的质量分数、门尼粘度、硫化特性、300%定伸应力、拉伸强度、扯断伸长率)的测试及评价方法,确定了EPDM挥发分的测定采用烘箱B法;门尼粘度的制样采用直接法;硫化特性的测定采用圆盘振荡硫化仪或无转子硫化仪;同时确定了评价硫化胶拉伸性能的条件,平行测定EPDM 3045和EPDM 3080,其300%定伸应力、拉伸强度和扯断伸长率重复性好。
        The test and evaluation methods of the physical and chemical properties(volatile,Mooney viscosity,vulcanization characteristics,300% tensile stress,tensile strength,elongation at break) for EPDM were studied. The oven method,procedure B for determination of volatile was determined; the method of preparing the test sample for Mooney viscosity without milling was determined; the method of determining vulcanization characteristics by the oscillating disc curemeter and the rotorless curemeter was studied; the conditions for evaluating the tensile properties of vulcanized rubber were determined and the results showed that the repeatability of 300% tensile stress at a given elongation,tensile strength and elongation at break was good.
