摘要
通过端羧基丁腈液态橡胶(Carboxyl Terminated Butadiene Acrylonitrile,CTBN)协同纳米Al2O3、SiO2颗粒与微米MoS2颗粒共混改性环氧树脂,制备了双组分的耐磨高分子合金修补剂材料。采用拉伸、摩擦磨损等试验及SEM等方法测试和分析了该高分子合金修补剂的拉伸强度、显微硬度等基本性能及摩擦学性能,并对其耐磨减摩机理进行了分析。结果表明:该材料的拉伸强度为42.3MPa,拉伸剪切强度为13.8MPa,显微硬度为231.1MPa,摩擦因数为0.17,耐磨性比LY12铝合金提高了50%。
The two-component epoxy resin (ER) polymer alloys putty toughened and modified by using liquid carboxyl terminated butadiene acrylonitrile (CTBN) and inorganic particles including SiO2,Al2O3 nano-particles and MoS2 micro-particles is prepared in room temperature. Its properties including tensile strength,shear strength,micro-hardness friction and wear characteristics are tested and analyzed by friction and wear testers,scanning electron microscopy (SEM) and so on. Its friction mechanism has been also discus...
