Development And Performance Of The New Foil Rolling Oil

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.
