Abstract

The invention discloses water-based lubricating oil. The water-based lubricating oil is prepared from the following substances in parts by weight: 60-80 parts of water, 7-10 parts of zinc diammonium ethylenediaminetetraacetate, 4-8 parts of N,N-diisopropylethanolamine, 10-15 parts of polyoxyethylene polyoxypropylene ether, 7-12 parts of histamine phosphate, 3-6 parts of chloroquine phosphate, 10-15 parts of 4-methylsalicylic acid, 12-15 parts of hexamethyl disiloxane, 10-18 parts of polyethylene glycol, 7-10 parts of 2-hydroxyl-4-dodecaoxydiphenylketone, 5-10 parts of nalidixate sodium, 2-6 parts of potassium ethyl xanthate, 3-8 parts of dimethylaminoborane and 3-7 parts of 1,3,5-trimethylpyrazole. The water-based lubricating oil takes water as a carrier and a plurality of chemical components are added, so that the lubricating performance of the water-based lubricating oil is improved.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a water-based lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is prepared by blending base oil and additives in a certain proportion; base oil determines the basic properties of lubricating oil and is the main component of lubricating oil; additives can improve performance. According to the classification of base oils, lubricating oils are divided into two types. One is made of mineral base oils and various special-effect additives; the other is synthetic oils produced by chemical methods. This oil has better performance than mineral oils. Oil is better, but also a bit more expensive. [0003] Mineral base oil is mainly prepared from crude oil through atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing and other methods. Reasonable addition of additives can improve its physical and...
