Preparation and Tribological Properties of Sulfide Transesterified Black Soldier Fly Oil

  • 摘要: 为解决矿物润滑油带来的环境污染问题,开发1种高度可生物降解润滑油至关重要. 以黑水虻油脂为原料通过酯交换反应和硫化反应制备了硫化酯交换黑水虻油(STBSO)润滑油添加剂. 采用傅里叶变换红外光谱(FTIR)对其结构进行了表征,考察了STBSO对基础油150N黏温性能、氧化安定性和抗腐蚀性能的影响. 利用四球摩擦试验机和SRV摩擦磨损试验机研究了STBSO对基础油150N极压抗磨性能的影响,并与商用硫化植物脂肪酸酯添加剂RC 2411进行了比较. 采用扫描电子显微镜(SEM)和X射线能谱(EDAX)分析了钢球磨损表面形貌和元素组成,结合X射线光电子能谱(XPS)分析,探究了STBSO的抗磨机理. 结果表明:STBSO作为润滑油添加剂可以有效提高基础油150N的黏温性能和氧化安定性,向基础油150N中添加质量分数为5%的STBSO后腐蚀等级为1b. 当STBSO的质量分数为5%时,润滑油的抗磨性能较优. 在相同的质量分数和载荷下,STBSO的摩擦学性能优于RC 2411.

     

    Abstract: In order to solve the environmental pollution problem caused by mineral lubricants, it is crucial to develop a highly biodegradable lubricant. Sulfurized transesterified black soldier fly oil (STBSO) was synthesized with black soldier fly lipid by transesterification and sulfurization reactions, and its structure was characterized by FTIR. The effect of STBSO on the viscosity-temperature property, oxidation stability and corrosion resistance of the base oil 150N was investigated. The influence of STBSO on the tribological behavior of the base oil 150N was evaluated by four-ball friction tester and SRV oscillating friction and wear tester. The wear surface morphology and elemental composition of the tribofilms were analyzed by scanning electron microscopy (SEM) and energy dispersive X-ray (EDAX) analysis, respectively. Based on SEM and EDAX analysis, combined with X-ray photoelectron spectroscopy (XPS) analysis, the anti-wear mechanism of STBSO was explored. The results demonstrated that the addition of STBSO can effectively improve the viscosity and viscosity index of the base oil 150N. With the increase of STBSO addition, the viscosity and viscosity index of the base oil 150N gradually increased. The oxidation stability test results manifested that the addition of STBSO can greatly increase the oxidation stability of the base oil 150N. The addition of 1% STBSO to the base oil 150N increased the induction time from 105 min to 121 min. The base oil 150N with addition of 5% STBSO had a corrosion degree of 1b. The simple friction wear test results showed that the addition of 1% STBSO to the base oil 150N significantly reduced the wear mass loss of the steel ball, however, when the STBSO addition was above 5%, the improvement in the anti-wear performance of the lubricant was no longer significant as the STBSO addition increased. The four-ball test results revealed that the maximum non-seizure load (PB) of the base oil 150N with 5% STBSO was 1 254 N, an improvement of 12.3% in the maximum non-seizure load and a 6.4% reduction in scar diameter compared with RC 2411. The SRV test results indicated that the friction coefficient of the base oil 150N with 5% STBSO remained stable (0.127), and was lower than that of the base oil 150N with 5% RC 2411 at a constant load of 300 N. The friction coefficient of the base oil 150N with 5% STBSO was always less than that of the base oil 150N with 5% RC 2411 for a given load at a continuous variable load from 50 N up to 700 N. When the load increased to 600 N, the original boundary lubrication films formed by the base oil 150N with RC 2411 broke down, but the base oil 150N with 5% STBSO still showed good anti-wear performance.
