By adding n-CuO, the friction mechanism of fluorosilicone rubber is changed, resulting in reduced friction coefficient and wear loss, enhancing the friction properties of the rubber matrix. Additionally, the tearing property of FVMQ is improved by altering the crosslinking density with the addition of n-CuO.
In order to study the effect of nanocopper oxide (n-CuO) on the friction properties of fluorosilicone rubber (FVMQ), the mechanical blending method was used by adding n-CuO in preparation of FVMQ. Characterization of scanning electron microscopy, X-ray diffraction analysis, energy dispersive spectroscopy, and so on were utilized for studying the mechanism of n-CuO in FVMQ. The experimental test on tensile, tear, and friction performance were performed on n-CuO/FVMQ at both room temperature (RT) and 200 degrees C. In comparison with n-CuO /FVMQ, the wear depth of FVMQ increased by 52.933 and 5.605 mu m for RT and 200 degrees C, respectively. Besides, the wear loss of FVMQ increased by 2.9 and 5.3 mg, respectively. The results show that for both at RT or 200 degrees C, the addition of n-CuO changes the friction mechanism of FVMQ. The friction coefficient and wear loss of FVMQ are effectively reduced, so that the friction property of rubber matrix is significantly enhanced. In addition, the tearing property of FVMQ is improved by adding n-CuO to change the crosslinking density of FVMQ.
