Example Embodiment
[0015] Example 1
[0016] The formula weight percentage of Example 1 is: n-hexanol: 8.0%; mixture of cinnamyl alcohol and cinnamic acid: 4.0%; coumarin: 0.50%; and the balance of mineral oil D80.
[0017] Formulated by weight, the preparation steps are as follows:
[0018] Mix cinnamyl alcohol and n-hexanol in any order, heat at 50°C, stir until uniform, add coumarin, continue to heat at 50°C, stir until completely dissolved, then add the remaining base oil, stir until uniform That's it.
Example Embodiment
[0019] Example 2
[0020] The formula weight percentage of Example 2 is: mixture of n-hexanol, n-heptanol, n-octanol and n-nonanol: 9.0%; mixture of cinnamyl alcohol and cinnamic acid: 4.5%; coumarin: 2%; and the balance of mineral oil D80, D85 , D90 and D95 mixture.
[0021] Formulated by weight, the preparation steps are as follows:
[0022] Mix the mixture of cinnamyl alcohol and cinnamic acid, and the mixture of n-hexanol, n-heptanol, n-octanol and n-nonanol in any order, heating at 50℃, after stirring until uniform, add coumarin, continue heating at 50℃ Next, stir until completely dissolved, then add the remaining base oil, and stir until uniform.
Example Embodiment

Abstract
The invention discloses coumarin-containing aluminum rolling oil and a preparation method thereof, belonging to the technical field of processing and lubrication. The invention mainly aims to solve the technical problems that traditional aluminum rolling oil contains phosphorus, sulfur and chlorine extreme pressure agents, is not beneficial for environmental protection, easily causes surface annealing oil spots and corrosion and the like. The coumarin-containing aluminum rolling oil provided by the invention comprises the following components in percentage by weight: 8.0%-10.0% of fatty alcohol, 4.0%-5.5% of a cosolvent and 0.50%-3.0% of coumarin, with the balance being base oil. The main additive of the coumarin-containing aluminum rolling oil is a natural compound, so the problem of environmental pollution is effectively solved, the lubricating property of the coumarin-containing aluminum rolling oil under high-speed wide-width high-pressure rolling conditions can be obviously improved, surface quality is remarkably improved, and the wear degree of a workpiece is reduced.
Description
technical field [0001] The invention relates to the technical field of lubrication and is used for process lubrication in metal processing, in particular to aluminum rolling oil containing coumarin and a preparation method thereof. Background technique [0002] In order to meet the development requirements of high-speed, wide-width, and high-pressure aluminum rolling technology, traditional aluminum rolling oils use extreme-pressure anti-wear agents containing active elements such as phosphorus, sulfur, and chlorine to improve the oil film strength. Although phosphorus, sulfur and chlorine anti-wear extreme pressure agents have good process lubrication performance, they are very easy to cause annealing oil spots, cause corrosion, and reduce the surface quality of aluminum strips and foils. At the same time, compounds containing phosphorus, sulfur and chlorine are easy to Cause environmental problems, do not meet environmental protection requirements. The new aluminum rollin...
