生物基抗磨剂和热轧油的研制

Study on Anti-Wear Additive and Hot Rolling Oil From Bio-Material

以植物油为原料,与丙三醇反应,制备了脂肪酸单甘油酯、双甘油酯;脂肪酸单甘油酯、双甘油酯与五硫化二磷反应,得到了硫磷酸;进一步与氧化锌反应,合成了硫磷酸锌抗磨剂。以生物柴油为原料,与多元醇反应,合成了不同黏度的多元醇酯基础油。以此基础油制备了热轧油,评价了其黏度和黏温性能、极压抗磨性能、离水展着性。结果表明,制备的抗磨剂具有良好的抗氧化、极压抗磨性能,制备的生物基多元醇酯基础油具有良好的黏温性能,研制的热轧油的抗磨性、油膜强度、烧结负荷和破乳时间等性能与参比油样相当或更好。

Anti-wear additive was synthesized with vegetable oil as raw material. The vegetable oil reacted with glycerol, and then the resultant reacted with phosphorus pentasulfide. Finally, the second resultant reacted with zinc oxide to get zinc dithophosphate, which was used as the anti-wear additive, and its anti-oxidation, anti-wear and extreme pressure properties were evaluated. Meanwhile, the bio-base oil was prepared with the bio-diesel and trimethylol propaneas raw materials, and then the hot rolling oil was prepared from the bio-base oil. The viscosity index, anti- wear and extreme properties of hot rolling oil were evaluated. The comparison between prepared and the imported hot rolling oils was carried out. It was found that the prepared anti-wear additive possessed good anti-oxidation and anti-wear and extreme properties, and the prepared bio-base oil possessed good characterization of viscosity-temperature, as well as the prepared hot rolling oil was better than reference oil in the properties of anti-wear, oil film strength, welding load and demulsification time.
