摘要
为了提高环氧树脂的韧性和耐磨损性能,运用全硫化纳米羧基丁腈橡胶（VP-501）颗粒对环氧树脂（E51）进行了增韧改性处理,制备了纳米橡胶颗粒增韧环氧树脂,研究了其摩擦学性能和磨损机理.结果表明：纳米橡胶颗粒的引入,有效改善了环氧树脂的断裂韧性,提高了11.5％ ～21.1％;添加适量纳米橡胶颗粒（6 phr）,可显著提高环氧树脂的耐磨损性能,含6 phr纳米橡胶颗粒增韧环氧树脂的耐磨损性能比纯环氧树脂提高1.3 ～9倍.纯环氧树脂的磨损机理以微观脆性断裂磨损为主;含6 phr纳米橡胶颗粒增韧环氧树脂的磨损机理主要是黏着磨损.
In order to improve the wear resistance and toughness of epoxy resin, full-vulcanized powdered nano rubber （VP-501） was used to toughen the epoxy resin （E51） and the nano-rubber particles toughened epoxy resin was prepared. The tribological properties and wear mechanisms of the toughened epoxy were investigated. The result shows that the fracture toughness of the toughened epoxy is effectively improved due to the introduction of nano-rubber particles, which increases by 11.5% -21.1%. Adding the moderate content of nano-rubber particles （6 phr） can significantly improve the wear resistance of the epoxy. The wear resistance of the toughened epoxy containing 6 phr nano-rubber particles increases by 1.3 - 9 times than that of neat epoxy. The wear mechanism of neat epoxy is microscopic brittle fracture mainly but the wear mechanism of the toughened epoxy is adhesive wear mainly.
