摘要
采用热模压硫化工艺制备了不同炭黑含量的芳纶织物1414增强三元乙丙/丁基橡胶复合材料(EPDM/IIR/PPTA),对其拉伸性能、撕裂强度、剥离强度和剥离形貌等进行了研究。结果表明:随着炭黑填充比例增加,复合材料的拉伸强度和断裂伸长率均降低,撕裂强度略有下降,剥离强度呈下降的趋势;炭黑的填充量小于30质量份时,复合材料主要表现为内聚破坏,炭黑填充量大于30质量份时,复合材料主要表现为胶粘界面破坏。
Ethylene-propylene terpolymer (EPDM) and isobutylene-isoprene rubber (IIR) composite reinforced with aramid fabric 1414 containing different proportions of carbon black (CB) were prepared by heat molding and vulcanization process, and their tensile properties, tear strength, peel strength and peel morphology were studied. The results show that, increasing the proportions of CB, the tensile strength and elongation at break decreased, tear strength decreased slightly and peel strength exhibited decrease trend. When the proportion of CB was below 30 phr, the composites exhibited cohesive failure. When the proportion of CB was more than 30 phr, the composites was mainly manifested in adhesive interface failure.
