以生物降解能力强且综合性能好的菜籽油作为基础油,以极压和抗磨性能较好的纳米材料作为添加剂,采用MS-800型四球磨损试验机对试验油极压特性、抗磨性能和摩擦因数进行了研究,分析不同纳米陶瓷添加量对其性能的影响;通过现有润滑油性能的对比,采用均匀设计安排试验,应用SPSS软件对纳米材料与其他添加剂的配伍性进行了回归分析。结果表明:纳米陶瓷添加剂的加入使菜籽油的摩擦性能显著提高,且加入比例得当能满足润滑油的要求;当纳米陶瓷的添加量(质量分数)为1.5%时,相应的最大无卡咬负荷PB值最高达646.8N,磨斑直径最小达0.59mm,摩擦因数最大可降低27%;纳米陶瓷与其他添加剂的复配以及相互作用可提高菜籽油的极压和抗磨性能。
The biodegradable and stable performance of rapeseed oil as a base oil, extreme pressure and anti-wear properties of nanomaterials as an additive, the use of MS-800-type four-ball wear testing machine extreme pressure test oil, anti-wear Performance and friction coefficient were studied to analyze the effect of different nano-ceramic addition amount on its performance. Through the comparison of the performance of the existing lubricating oil, the uniform design and arrangement test was carried out. The compatibility of nano-material and other additives was regressed using SPSS software analysis. The results showed that the addition of nano-ceramic additive increased the frictional properties of rapeseed oil significantly, and the proper proportion of the rapeseed oil could meet the requirements of the lubricating oil. When the nano-ceramic addition amount (mass fraction) was 1.5% The maximum PB value is up to 646.8N, the diameter of wear scar is up to 0.59mm, and the maximum friction coefficient can be reduced by 27%. The compound and interaction between nano-ceramic and other additives can increase the extreme pressure and antiwear performance of rapeseed oil.
