preparation example Construction
[0051] The present invention also provides a method for preparing the above-mentioned special high-temperature lubricating oil for continuous press steel strips in the plate processing industry, including:
[0052] a) mixing the aromatic acid mixed alcohol ester with a tackifier to obtain a base oil;
[0053] b) After heating and mixing the base oil, antioxidant, extreme pressure anti-wear agent, anti-corrosion agent and equalizer obtained in the above steps, a high-temperature lubricating oil for continuous press steel strips in the plate processing industry is obtained.
[0054] In the present invention, the aromatic acid mixed alcohol ester is first mixed with the tackifier to obtain the base oil; the mixing temperature is preferably 90°C to 100°C, more preferably 96°C to 100°C; the present invention has no special limitation on the mixing method , get final product with the mixing method well-known to those skilled in the art, and the present invention is preferably agitat...
