摘要
三元乙丙橡胶(EPDM)具有良好的耐候性、耐臭氧性、耐水性以及耐化学腐蚀性。为使三元乙丙橡胶的拉伸强度>10 MPa、压变(100℃×22 HR)≤30%、体积变化率<10%,以满足工业上的需要,以三元乙丙橡胶作为研究对象,选取生胶门尼黏度、操作油的黏度、填料的种类及填料的用量为工艺参数进行正交实验,制备不同配方下的硫化橡胶,并对其物理性能进行测量。在此基础上,使用极差分析法得到工艺参数对性能指标的影响主次顺序,随后基于灰色关联理论对实验数据进行多指标简化处理。结果表明:当生胶门尼选用朗盛6950、操作油选用P600、填料使用30份的N774时,三元乙丙橡胶的拉伸强度为13 MPa,压变为30.26%,体积变化率为2.8%。
Ethylene propylene diene monomer(EPDM)rubber has good weather resistance,ozone resistance,water resistance,and chemical corrosion resistance.In order to increase the tensile strength of EPDM rubber to>10 MPa and the compressive strain(100℃×22 HR)≤30%,volume change rate<10%to meet industrial needs,the article takes EPDM rubber as the research object,selects raw rubber Mooney viscosity,operating oil viscosity,filler type and filler dosage as process parameters for orthogonal test,prepares vulcanized rubber under different formulations through experimental methods,and measures its physical properties.On this basis,the range analysis method is used to determine the primary and secondary effects of process parameters on performance indicators.Subsequently,the experimental data is simplified using multiple indicators based on grey correlation theory.The results show that when using Langsheng 6950 as raw rubber,P600 as operating oil,and 30 phr of N774 as filler,the tensile strength of EPDM rubber is 13 MPa,the compressive strain is 30.26%,and the volume change rate is 2.8%.
