Embodiment 1

[0018] Example 1, the lubricating oil extreme pressure agent is obtained according to the following preparation method: the first step, adding concentrated sulfuric acid to vegetable oil for reaction, and the first mixed liquid is obtained after the reaction; the second step, adding alkali or lye to adjust the first The pH value of the mixed solution is adjusted to obtain the second mixed solution; in the third step, the second mixed solution is dehydrated to obtain a lubricating oil extreme pressure agent. The lye can be saturated lye.

Embodiment 2

[0019] Embodiment 2, as the optimization of above-mentioned embodiment, in the first step, the add-on of concentrated sulfuric acid is 5% to 10% of vegetable oil quality; Or / and, in the first step, concentrated sulfuric acid joins in vegetable oil, at temperature React at 20°C to 60°C for 50min to 90min; or / and, in the first step, the concentrated sulfuric acid and vegetable oil are reacted under stirring, and the stirring rate is 60rpm to 100rpm.

Embodiment 3

[0020] Example 3, as an optimization of the above example, in the second step, add alkali or lye to adjust the pH value of the first mixed solution to 7 to 8; or / and, in the second step, the alkali is sodium hydroxide or hydroxide Calcium; lye is sodium hydroxide aqueous solution or calcium hydroxide aqueous solution.

Abstract

The invention relates to the technical field of lubricating oil extreme pressure agents, in particular to a lubricating oil extreme pressure agent and a preparation method of the lubricating oil extreme pressure agent. The preparation method of the lubricating oil extreme pressure agent comprises the steps that firstly, concentrated sulfuric acid is added to vegetable oil to perform a reaction, and after the reaction, a first mixed solution is obtained; secondly, alkali or an alkali solution is added so that the pH value of the first mixed solution is adjusted, and a second mixed solution is obtained after adjustment; thirdly, the second mixed solution is dehydrated, and therefore the lubricating oil extreme pressure agent is obtained. According to the lubricating oil extreme pressure agent and the preparation method of the lubricating oil extreme pressure agent, compared with an existing lubricating oil extreme pressure agent, the lubricating oil extreme pressure agent is lower in cost and can better meet existing production requirements.

Description

technical field [0001] The invention relates to the technical field of lubricating oil extreme pressure agents, and relates to a lubricating oil extreme pressure agent and a preparation method thereof. Background technique [0002] Extreme pressure agents are widely used in the lubricant industry, especially in metalworking fluids. However, the existing extreme pressure agents for lubricating oil have the problems of high production cost and poor extreme pressure performance. Contents of the invention [0003] The invention provides an extreme pressure agent for lubricating oil and a preparation method thereof, which overcomes the above-mentioned deficiencies in the prior art and can effectively solve the problems of high production cost and poor extreme pressure performance of the existing extreme pressure agent for lubricating oil. [0004] One of the technical solutions of the present invention is achieved by the following measures: a lubricating oil extreme pressure a...
