摘要:
采用机械共混法将酚醛树脂(PF)与丁腈橡胶(NBR)进行混合而制得PF/NBR复合材料,研究了PF用量对NBR的拉伸性能、撕裂性能及硬度的影响,使用多功能材料表面性能综合测试仪、三维表面形貌仪和扫描电子显微镜对力学性能最优的PF/NBR复合材料试样A 2(添加5份PF)在不同温度下的摩擦性能进行了探究,并与未添加PF的试样A 0进行了对比,此外还对PF/NBR复合材料的磨损机理进行了初步分析。结果表明,当温度超过75 ℃时,试样A 0的摩擦系数曲线整体呈持续上升的趋势,同时其表面有较多孔洞,分子间结合力下降,耐磨性变差,而试样A 2的摩擦系数则基本保持稳定,磨损行为表明其磨损机理由磨粒磨损逐渐转变为黏着磨损;相对于试样A 0而言,试样A 2在高温下仍能保持较好的摩擦性能。
Abstract:
Phenol formaldehyde resin (PF)/nitrile rubber (NBR) composites were prepared by mecha-nical blending of PF and NBR, and the effect of the amount of PF on tensile strength, tear strength and hardness of PF/NBR composites was studied. The friction performance of PF/NBR composite sample A 2 (containing PF of 5 phr) with the best mechanical properties was explored at different temperatures using multifunctional integrated tester for surface properties of materials, three-dimensional surface profilometer and scanning electron microscope, and compared with that of sample A 0 not containing PF. Furthermore, the wear mechanism of PF/NBR composite was preliminarily analyzed. The results showed that when the temperature was more than 75 ℃, the friction coefficient curve of sample A 0 was on an upward trend, and at the same time, there were more holes on the surface of sample A 0, the intermolecular binding force decreased, and the wear resistance got poor. While the friction coefficient of sample A 2 remained basically stable, the abrasive wear behavior indicated that the wear mechanism varied gradually from abrasive wear to adhesive wear. Compared with sample A 0, sample A 2 could still maintain better friction performance at high temperature.
