reference example 1

[0030] Weigh 100 ml of absolute ethanol, 1100 g of castor oil, and 40 g of tetrabutyl titanate into the reaction kettle, react for 8 hours under normal pressure and 40°C, and then distill the ethanol out in a vacuum distillation device , the pressure is -0.1MPa~-0.001MPa, the temperature is 25~60°C, and the modified vegetable oil can be obtained.

reference example 2

[0032] Weigh 100 ml of absolute ethanol, add 1100 g of peanut oil, and 25 g of tetrabutyl titanate into the reaction kettle, react for 6 hours under normal pressure and 60°C, and then distill the ethanol out in a vacuum distillation device, namely Modified vegetable oils are available.

reference example 3

[0034] Weigh 100 milliliters of absolute ethanol, 1100 grams of rapeseed oil, and 40 grams of tetrabutyl titanate into the reaction kettle of the reaction distillation device. The modified vegetable oil can be obtained by distilling ethanol out under reduced pressure in vacuum.

Abstract

The invention provides an environmental protection type lubricating grease composition. The composition comprises basic grease and an additive, wherein the basic grease comprises the following ingredients in percentage by weight: 60 to 95 percent of basic oil and 5 to 40 percent of composite lithium soap thickener; and the additive comprises the following ingredients based on the 100 weight percent of the basic oil: 0.05 to 2 percent of antioxidant, 0.5 to 10 percent of extreme pressure anti-wear agent and 0.1 to 2 percent of anti-rusting agent. The environmental protection type lubricating grease composition has high high-low temperature adaptability, high biodegradability, excellent an anti-oxidation, shear resistance and extreme pressure wear resistance and high anti-rusting property and corrosion inhibition, and is suitable to be used as the lubricating grease for bearings of electromotors of rail locomotives.

Description

technical field [0001] The invention relates to an environment-friendly lubricating grease composition, in particular to an environment-friendly lubricating grease composition suitable for high-speed railway traction locomotive motor bearings. Background technique [0002] The traction locomotive is the main equipment in the transmission system of the electric locomotive and the electric transmission diesel locomotive, and the bearing is an important part of the traction locomotive. The characteristics of traction motor bearings are that the bearings are affected by the temperature rise caused by the heat of the motor under the condition of grease lubrication, while rotating at high speed, and the load on the bearings varies depending on the driving method. Therefore, the traction motor has the characteristics of high power, high armature speed and high bearing operating temperature. [0003] At present, the traction power of high-speed railways is electric traction, except...
