[0030] Step 2: When the temperature was lowered to 100° C., 1.5 g of the introduction agent lauroyl peroxide was added, and the stirring was continued to fully react for 10 hours to obtain a lubricating oil composition.

[0031] The above lubricating oil composition is applied to the TIMKEN experimental machine for repair experiments:

[0032] Add 32# mechanical oil to the oil tank of the TIMKEN experimental machine, install new rollers, turn on the motor switch, add weights continuously, and when the weights are added to 50 pounds, the motor makes a sharp noise. There is wear with a diameter of about 6 mm (longitudinal), and the wear surface is rough. Replace the mechanical oil in the oil tank with the above-mentioned lubri...

Embodiment 2

[0037] Step 1: Weigh 929.26g (1mol) of castor oil, 139.28g (1.2mol) of fumaric acid, and 1.5g of cerium oxide into the reaction kettle together, stir and heat to 180°C, fully react for 4 hours, and discharge the water under reduced pressure;

[0038] Step 2: When the temperature is lowered to 120° C., add 0.7 g of methyl ethyl ketone peroxide as an introducing agent, continue to stir and fully react for 8 hours, and a lubricating oil composition is obtained.

[0039] Weigh 100g of the lubricating oil composition prepared above, 800g of propylene glycol dicaprylate, 80g of ricinoleoyl monoethanolamine, and 20g of sodium cocoyl alanine, and mix and stir at 40°C until it becomes transparent. lubricating oil.

[0040] The preparation method of above-mentioned ricinoleoyl monoethanolamine:

[0041] Weigh 298.46 g (1 mol) of ricinoleic acid and 30.54 g (0.5 mol) of monoethanolamine into a stirrer, stir and heat to 110°C, and fully react for 1.5 hours to obtain ricinoleoyl monoethan...

Embodiment 3

[0043] Step 1: Weigh 929.26g (1mol) of castor oil, 116.07g of maleic acid (1mol) of maleic acid, and 2.5g of lanthanum oxide into the reaction kettle together, stir and heat to 190°C, fully react for 3.5 hours, and discharge the water under reduced pressure;

[0044] Step 2: When the temperature is lowered to 110° C., add 1 g of diisopropyl peroxydicarbonate as an introducing agent, continue to stir and fully react for 9 hours, and a lubricating oil composition is obtained.

[0045] Weigh 150g of the lubricating oil composition prepared above, 750g of propylene glycol dicaprylate, 60g of ricinoleoyl monoethanolamine, and 40g of sodium cocoyl alanine, mix and stir at 50°C until it becomes transparent, which is a sub-drying process lubricating oil.

[0046] The preparation method of above-mentioned ricinoleoyl monoethanolamine:

[0047] Weigh 298.46 g (1 mol) of ricinoleic acid and 61.08 g (1 mol) of monoethanolamine into a stirrer, stir and heat to 110°C, and fully react for 1...

Abstract

The invention provides a lubricating oil composition. The lubricating oil composition is characterized by being prepared from castor oil, butenedioic acid and rare earth oxide, wherein the mole ratioof the castor oil to the butenedioic acid is 1:1-1:1.5, and the rare earth oxide accounts for 0.1-0.5% of the weight of the composition, and is preferably one of lanthanum oxide and cerium oxide or amixture of the lanthanum oxide and cerium oxide. The invention provides a near-dry processing lubricating oil containing the lubricating oil composition. The near-dry processing lubricating oil is characterized by being prepared from, by weight, 10-20% of the lubricating oil composition, 70-80% of propylene glycol dicaprylate, 5-10% of ricinoleic acid-glycollic amide and 2-5% of sodium cocoyl alaninate. The near-dry processing lubricating oil prepared from the lubricating oil composition can meet the requirements of metal processing for lubricating cooling, extreme-pressure wear resistance andrust prevention. When the near-dry processing lubricating oil is used in cooperation with a near-dry cutting lubricating device, the use quantity of a lubricant can be saved by 95% or above, and theeffects of energy conservation and emission reduction and environmental protection are significant.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a lubricating oil composition, a preparation method thereof and the use of the composition to prepare sub-dry processing lubricating oil. Background technique [0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators. , to solve these problems. Recently, some progress has been made in the research of sub-dry cutting technology. Sub-dry cutting is a new type of machining lubrication and cooling technology between dry cutting and wet cutting, in order to achieve satisfactory cutting effect with the least cutting oil. Sub-dry cutting processing technology solves the above problems s...
