preparation example Construction

[0013] A method for preparing lubricating oil, characterized in that: the method for preparing lubricating oil includes the following steps: a. Weigh 0.1-1% by weight of fatty acid ester into the heating reactor attached, and heat the reactor To 60~70℃, make the fatty acid ester fully melt; b. Weigh 99-99.9% of the fatty solvent by weight, and add 3 to 5 times the weight of fatty acid ester to the fatty acid in step a In the ester solution and stir until it is uniform and non-colloid. Under this condition, use the pump to add the remaining weight of aliphatic solvent and stir it until the dissolution is complete; c. Transfer the configured lubricating oil into a clean oil drum with a seal , Sealed and stored. In step a, the reaction kettle is heated in an oil bath or a water bath, and the fatty acid ester can be one or a mixture of the following substances: carnauba wax, beeswax, paraffin wax and montan wax. Fatty acid esters can also be made by mixing 50% by weight beeswax an...

Embodiment 1

[0031] Lubricating oil raw materials and preparation methods are as follows:

[0032] Raw materials: fatty acid esters (paraffin wax and beeswax each account for 50%), aliphatic solvents (petroleum ether and 120# solvent each account for 50%). Paraffin wax (produced by Shanghai Huashen Rehabilitation Equipment Co., Ltd.): colorless and transparent solid, melting point: 58~62℃, insoluble in water, slightly soluble in alcohol. Beeswax (produced by Shanghai Huashen Rehabilitation Equipment Co., Ltd.): slightly yellow, insoluble in water, slightly soluble in alcohol. Melting point: 62~72℃.

[0033] Petroleum ether (produced by Shanghai Lelu Chemical Co., Ltd.): Main ingredients: pentane and hexane. Appearance and properties: colorless transparent liquid with kerosene smell. Melting point <-73℃, boiling range 90-120℃. Solubility: insoluble in water, soluble in most organic solvents such as absolute ethanol and oil. Main use: Mainly used as a solvent and as a grease extraction.

Abstract

The invention relates to a lubricating oil and a preparation method thereof and is characterized in that the lubricating oil is mixed by 0.1-1wt% of fatty acid ester and 99-99.9wt% of fatty group solvent, wherein the fatty acid ester is mixed by beeswax and paraffin, and fatty group solvent is a mixture of two or more solvents selected from a group of gasoline, industrial alcohol, 120# solvent, 200# solvent, cyclohexane, petroleum ether, absolute ethanol or xylene. The lubricating oil of the present invention has a premium lubricity and coating uniformity, a simple preparation method which is easy for operation, and a low price. In addition, coating the lubricating oil on an enamelled wire leaves no peculiar smell, so as to solve problem of ugly peculiar smell.

Description

Technical field: [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil applied on the surface of an enameled wire and a preparation method thereof. Background technique: [0002] In recent years, in order to increase the utilization rate of materials, reduce material consumption, increase the winding speed of coils, and reduce the volume of motor and electrical appliance coils, the electrical and electronic equipment manufacturing industry requires excellent use in the coils of electrical appliances or electronic equipment such as motors and transformers. Enameled wire with surface lubricity and wear resistance, and can adapt to winding under high speed, high strength and harsh conditions. In particular, in order to comply with the requirements of increasing the efficiency of motors proposed by the trend of energy saving in the 21st century, it is necessary to further improve the lubrication and wear resistance of the surface t...
