摘要 

运用共价官能化技术,实现纳米SiO2表面接枝3-氨丙基三乙氧基硅烷(APTES)改性(T-SiO2),并制备功能化纳米SiO2改性环氧树脂复合材料(T-SiO2/EP),分析改性后纳米SiO2表面官能团和化学元素的变化规律,测试T-SiO2/EP的主要力学性能,研究其在干摩擦条件下的摩擦磨损行为与机制。结果表明:功能化纳米SiO2的引入,有效改善了环氧树脂的力学与摩擦学性能,且当功能化纳米SiO2含量为2%时(质量分数,下同),环氧复合材料(2% T-SiO2/EP)的显微硬度和断裂韧度均达到最大值(70.2HD和1.02MPa·m1/2),并具有优异的减摩耐磨性能。干摩擦条件下,2% T-SiO2/EP复合材料的摩擦因数和磨损失重分别为0.49和1.7mg,较纯环氧树脂分别降低了31.9%和34.6%,较未改性纳米SiO2增强的环氧树脂复合材料(U-SiO2/EP)分别降低了14%和10.5%,并对相应的磨损机理进行了分析。

Abstract

Nano-SiO2 surface grafted APTES (T-SiO2) was realized by covalent functionalization technology, and functionalized nano-SiO2 modified epoxy resin composite (T-SiO2/EP) was prepared. The surface functional groups and chemical elements of the functionalized nano-SiO2were analyzed and the mechanical and tribological properties of the T-SiO2/EP were tested. The results show that the mechanical and tribological properties of the epoxy resin are effectively improved due to the introduction of functionalized nano-SiO2. When the content of functionalized nano-SiO2 is 2%(mass fraction, same as below), the microhardness and fracture toughness of the composites (2%T-SiO2/EP) can reach the maximum, which are 70.2HD and 1.02MPa·m1/2 respectively, moreover, in dry friction condition, the friction coefficient and the wear loss reach the minimum, which are 0.49mg and 1.7mg respectively. Compared with pure epoxy resin, they are reduced by 31.9% and 34.6%, and compared with 2% unmodified nano-SiO2 reinforced epoxy resin composite, they are reduced by 14% and 10.5%, and the corresponding wear mechanism is analyzed.
