preparation example Construction

[0035] First introduce the preparation method of castor oil soap boric acid complex:

[0036] a) Pump the measured castor oil and tap water into the reaction kettle, stir, and heat with heat transfer oil, and the temperature is controlled between 65°C and 95°C;

[0037] b) Slowly add triethanolamine into the reaction kettle, monitor the appearance of the mixture in the reaction kettle in real time, and stop adding triethanolamine when the appearance of the mixture reaches transparent and clear, which is the end point of the saponification reaction;

[0038] c) adding boric acid, controlling the reaction temperature at 80°C to 90°C, and the pH value at 7.5 to 8.5, and the production liquid after the reaction is a transparent castor oil soap boric acid complex solution.

[0039] Then introduce the preparation method of oleic acid triethanolamine:

[0040] a) pump metered oleic acid and triethanolamine into the reactor, stir and heat;

[0041] b) When the temperature reaches 12...

Embodiment 1

[0044] a) Add the solution of castor oil soap boric acid complex and triethanolamine oleate into the reaction kettle, stir evenly, and control the temperature at 45°C;

[0045] b) adding water, bactericide, defoamer, preservative and rust preventive to the reactor in sequence;

[0046] c) adding polyoxyethylene polyoxypropylene ether to adjust to a specified viscosity, and then obtaining a water-based lubricating oil.

Embodiment 2

[0048] a) Add the solution of castor oil soap boric acid complex and triethanolamine oleate into the reaction kettle, stir evenly, and control the temperature at 55°C;

Abstract

The invention discloses a water-base lubricant and a preparation method thereof. The water-base lubricant comprises the following compositions: monopol soap boric acid complex, triethanol amine oleate, viscosity modifier and water. Compared with the prior art, the water-base lubricant prepared by combining the monopol soap boric acid complex instead of monopol soap and the triethanol amine oleate greatly improves the maximum non-seizure load so as to improve the lubricating performance. The water-base lubricant is applicable to lubrication of gears and other mechanical components.

Description

technical field [0001] The invention relates to a water-based lubricating oil and a preparation method thereof, belonging to the field of lubricating oil. Background technique [0002] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. [0003] 1. Lubricant base oil [0004] Lubricant base oils are mainly divided into two categories: mineral base oils and synthetic base oils. Mineral base oils are widely used and used in a large amount (about 95%), but in some applications, products formulated with synthetic base oils must be used, thus making synthetic base oils develop rapidly. [0005] Mineral base oils are refined from crude oil. The main production processes of lubricating oil base oil are: atmospher...
