摘要

摘要: 利用纳米粉末橡胶结合无机纳米氧化铝以改善环氧树脂的表面强度性能和摩擦性能.采用差示扫描量热法(DSC,Differential Scanning Calorimeter)研究了纳米改性环氧树脂的固化反应动力学; 采用动态超微硬度表征了纳米复合材料的表面强度; 评价了纳米改性环氧树脂复合材料的摩擦系数.结果表明, 纳米复合材料与环氧树脂具有相同的固化反应机理, 单一纳米粒子的加入降低了固化反应的表观活化能, 两种纳米粒子的复配使用增加了固化反应的表观活化能.纳米粒子使固化反应程度下降, 导致固化反应热显著下降.复配使用纳米氧化铝和纳米粉末橡胶能够改善环氧树脂复合材料的摩擦系数、表面硬度和弹性模量, 实现了对表面强度性能和摩擦性能的优化.

Abstract: The surface strength and tribological properties of epoxy resin were modified with addition of alumina nano-particles and rubber nano-powders. The curing kinetics and the surface strength properties of epoxy nanocomposites were investigated by differential scanning calorimeter (DSC) and dynamic ultra-micro hardness tester, respectively. The friction coefficient of the composites was evaluated. The results reveal the same curing mechanism of nanocomposites as epoxy resin by showing the similar reaction order. The activation energy of nanocomposites with single kind of nano-particles was decreased while the one with mixed nano-particles was increased. The curing heat was decreased due to the suppressed curing degree by nanoparticles. The surface hardness and the elastic modulus were improved, as well as the creep-resistant and deformation-resistant properties. Conclusively, the surface strength properties and friction coefficient of epoxy composites were improved with addition of mixed nano-particles.
