Embodiment 1

[0022] The concrete preparation process of modified vegetable oil is as follows:

[0023] Step 1, mix cottonseed oil, soybean oil and castor oil according to the mass ratio of 1:2.1:0.8 to obtain mixed oil, add 1kg of mixed oil into the reaction kettle and raise the temperature to 60-65°C, then oxidize 13g of hydrogen Add sodium into 240g of crotyl alcohol, stir and mix evenly, then add it to the reaction kettle, keep the temperature constant and stir for 4-5h, after the product is layered, the upper oil layer is washed until neutral and then dried to obtain pretreated vegetable oil. The reaction structure is as follows;

[0024]

[0025] Step 2, weigh a certain amount of acrylamide and dissolve it in ethanol, configure it as an acrylamide solution with a mass concentration of 60%, add 1 kg of the pretreated vegetable oil prepared in step 1 into the reaction kettle, and then continuously pass through the reaction kettle Into nitrogen for 30 minutes, then add 120g of benzoy...

Abstract

The invention discloses biodegradable lubricating oil. The biodegradable lubricating oil is prepared from the following components in parts by weight: 70 to 75 parts of modified vegetable oil, 3.4 to3.8 parts of a formaldehyde solution, 1.3 to 1.5 parts of an antioxidant, 0.6 to 0.7 part of a preservative, 0.8 to 1.2 parts of a wear-resistant auxiliary agent and 1.6 to 2.5 parts of a dispersing agent. The vegetable oil is used as base oil; after modification, the vegetable oil directly reacts with the preservative and the antioxidant through chemical action; the antioxidant and the preservative can be uniformly compounded on the base oil chain, so that the preservative and the antioxidant are uniformly dispersed, the oxidation resistance and the corrosion resistance of the lubricating oilare uniform, and the problem that the oxidation resistance and the corrosion resistance of the existing lubricating oil are influenced due to non-uniform mixing caused by directly adding the antioxidant and the preservative through physical action is solved.

Description

technical field [0001] The invention belongs to the field of lubricating oil preparation, and relates to a biodegradable lubricating oil and a preparation process thereof. Background technique [0002] In metallurgy, mining, and underwater operation machinery and equipment, gears, toothed discs, racks and chains, transmission mechanisms, hinges, and wire ropes are used. These mechanical parts are exposed to wind and rain for a long time and are easy to corrode. , and then affect the use, usually lubricating oil is used to lubricate and protect it. Through the role of lubricating oil, a certain anti-corrosion performance can be achieved. Contents of the invention [0003] The purpose of the present invention is to provide a biodegradable lubricating oil, which takes vegetable oil as the base oil, reacts with preservatives and antioxidants directly through chemical action after modification, so that the antioxidants and preservatives can be evenly compounded on the base On ...
