【摘要】 本文以上海高桥石化润滑油为原料，开发研制了高档的铝箔轧制油。论文选取国际顶级的ESSO商品铝箔基础油(2#)为参照样品，对多组不同馏程Chevron加氢润滑油(3#～14#)进行了考察研究，采用气质联用技术、紫外分光光度法和紫外荧光法分析了它们的化学组成，然后测定了这些油品的馏程、粘度、密度、表面张力、热稳定性、酸值等物化性能和油膜强度、退火性能、闪点等使用性能。研究表明，该Chevron加氢润滑油具有低硫、低芳烃特点，通过调配，可作为优质的铝箔轧制基础油，性能优于ESSO商品铝箔轧制基础油。论文考察探索了油品化学组成与性能之间关系，研究表明：油品轻质组份(碳链长度≤C11的组份)越多，油品的初馏点越低，且从初馏点到10％馏出温度的宽度越大；油品重质组份(碳链长度≥C15的组份)越多则油品的终馏点越高。粘度与油品的成分组成也有关，主要是由馏程决定，当初馏点相同时，终馏点愈高，粘度就愈高；当终馏点相同，初馏点愈低粘度愈低。基础油的闭口闪点与初馏点具有良好的线性关系：t_s=0.615t_i-45.9。基础油的油膜强度与其组成有关，如果基础油中碳链长度≥C13的组份含量太低则会影响其油膜强度。基础油的退火性能除与碳链长度、终馏点、粘度大小、芳烃和硫含量有关外，还与基础油成分的类型有关，且异构烷烃的退火性能较正构烷烃和环烷烃的好。添加剂可以改善和提高轧制油的使用性能，论文对CSA-P(醇酯型)、WYLOR-10(酯型)和WYLOR-12(醇型)等三种添加剂、用量及作用机理进行了研究，结果表明这些添加剂与基础油具有很好的相容性。增加添加剂用量可提高油样的粘度和油膜强度，但退火性能变差，最佳添加剂的用量为5～6％(W／W)。在实验研究基础上，以性能最佳的8#油为主体，调配成为工业试验用基础油(15#)，论文对15#油进行了性能综合测试，然后加入5～6％(W／W)CSA-P2添加剂制备成铝箔轧制润滑油。论文对该润滑油进行工业应用试验，研究表明，用该润滑油可以轧制出厚度为0.1mm左右、表观质量和退火性能优良的高精度铝箔，在一个月使用过程中，轧制性能稳定，综合指标达到了世界知名品牌ESSO第三代铝箔轧制油的水平。更多还原

【Abstract】 Slap-up rolling oil for aluminum foil has been developed by using the lubricating oil from Shanghai Gaoqiao Petrochemical Corporation. Several Chevron hydrogenation oils (3#～14#) have been researched by referring to the rolling basic oil for aluminum foil from ESSO(2#). Their chemical components were mensurated by GC-MS, Ultraviolet Spectrometry and Ultraviolet Fluorescence. The physical and chemical performances, including the distillation range, the viscosity, the density, the surface tension, the thermal stability and the acid number were mensurated. And the load-carrying capacity, annealing capacity and flash point were also mensurated separately. The results show that the Chevron hydrogenation oils have the traits of low aromatic and low sulfur. They can be used to the rolling basic oil for aluminum foil by preparing. And their perfomances are better than the rolling basic oil for aluminum foil from ESSO.The relation between the performance of the oil and its components has been reviewed. The results show that the more the light components, the lower the dropping point, the wider the width between the dropping point and the 10% recovered distilled temperature. The more the heavy components, the higher the end point of distillation. The viscosity is also connection with the components of the oil. It is mainly decided by the distillation range. When the dropping point is the same, the higher the end point of distillation gets higher viscosity. When the end point of distillation is the same, the lower the dropping point gets lower viscosity. And the flash point is linear realation to the dropping point: t_s=0.615t_i-45.9. The load-carrying capacity of the basic oil is connection with its components. If the content of the component, the length of carbon chain is more than thirteen is very slow, its load-carrying capacity will be affected. Beside the annealing capacity is connection with the length of carbon chain, the end point of distillation, the viscosity, the content of aromatic hydrocarbon and the content of sulfur, it is also connection with the type of component, the annealing capacity of isomeric alkyls is better than normal alkyls and cyclanes. Additives can improve the using performance of the rolling oil. The type (CSA-P, WYLOR-10 and WYLOR-12) and the quantity of the additives and the acting mechanism were studied. The results show that the consistency between the additives and the basic oil is very good. And the load-carrying capacity and the viscosity is increased, the annealing capacity becomes badder by adding the additives, so the appropriate quantity of additives is 5～6%.A basic oil (15#) is prepared by distilling and incising the eighth oil, then the additive of 5～6% CSA-P2 is added. It is evaluated by the laboratory tests and industry tests. The results show that it can roll the aluminum foil, whose thickness is about 0.1mm with good apparent and good annealing capacity. And the rolling performance is steady by using it for one month. Its synthetical performance reaches the level of the third era rolling oil for aluminum foil in ESSO.更多还原
