Description
Technical Field
The invention belongs to the technical field of metal rolling oil, and particularly relates to high-quality environment-friendly aluminum rolling oil and a preparation method thereof.
Background
In recent years, the equipment level of the aluminum rolling industry is greatly improved, such as wide rolling mills with working rolls of more than 2500mm in length, large-rolling-force rolling mills with working rolls of more than 400mm in roll diameter, and high-speed rolling mills with design working speed of 2000m/min are continuously emerging, and common application of 2-series, 5-series, 7-series single alloys and composite alloys brings great challenges to the process lubrication performance and also puts higher requirements on the performance of rolling oil. The following can be summarized: (1) better tribological performance; (2) better wetting performance, effectively reducing longitudinal bright and dark lines; (3) the bearing capacity is higher, the rolling force is reduced, and the rolling reduction is improved; (4) better corrosion protection; (5) excellent annealing cleaning performance. In addition, with increasingly harsh environmental protection methods and continuously enhanced environmental protection consciousness of people, the development of environment-friendly rolling oil becomes a consensus in the industry, and the demand of the market for novel environment-friendly rolling oil will increase increasingly.
At present, most of aluminum rolling oil on the market mainly comprises paraffin-based base oil, higher fatty alcohol and higher fatty acid ester, and due to the characteristics of poor low-temperature fluidity, poor solubility and the like of the paraffin-based base oil, the use environment and the compatibility with additives need to be considered; the combination of higher fatty alcohol and higher fatty acid ester also considers the compounding ratio of the higher fatty alcohol and the higher fatty acid ester and balances the lubricating property and the annealing property, which undoubtedly increases the preparation difficulty and the cost.
