Embodiment 1

[0037] Step 1, add 116.07kg (1000mol) of fumaric acid and 354.12kg (1900mol) of lauryl alcohol in the polymerization kettle, add 28kg of dilute sulfuric acid (5%), charge into nitrogen to convert the air in the polymerization kettle to react, after the reaction Decompress and discharge water, which is lauryl fumarate.

[0038] Step 2: Add 1.16kg of dibenzoyl peroxide initiator into the polymerization kettle and stir, keep the reaction temperature at 160°C, after 8 hours of polymerization reaction, discharge the polymer in the polymerization kettle, filter and remove it at a temperature above 100°C, etc. Impurities, that is, fumaric acid laurel resin.

[0039] Stir 30kg of the above-mentioned lauryl fumarate, 30kg of trimethylolpropane trioleate, 30kg of methyl oleate, 5kg of trilauryl phosphate, and 5kg of sodium lauryl sarcosinate at a temperature of about 100°C for 20 minutes , which is a degradable micro lubricant, naturally cooled packaging.

Embodiment 2

[0041] Step 1, the maleic acid of 116.07kg (1000mol) and the arachidyl alcohol of 597.1kg (2000mol) are added in the polymerizer, add 71.32kg dilute sulfuric acid (5%), fill into nitrogen and change the air in the polymerizer to react, react After decompression to discharge water, it is peanut ester maleate.

[0042] Step 2: Add 0.58kg of lauroyl peroxide initiator into the polymerization kettle and stir, keep the reaction temperature at 180°C, after 4 hours of polymerization, discharge the polymer in the polymerization kettle, filter and remove other impurities at a temperature above 100°C, It is maleic acid peanut resin.

[0043] Stir 10kg of the above-mentioned peanut ester maleate, 50kg of pentaerythritol tetralaurate, and 40kg of ethyl laurate at a temperature of about 100°C for 20 minutes to obtain a degradable micro-lubricating oil, which is naturally cooled and packaged.

Embodiment 3

[0045] Step 1, the maleic anhydride of 98.02kg (1000mol) and the stearyl alcohol of 527.59kg (1950mol) are added in the polymerizer, add 12.51kg cation exchange resin, charge into nitrogen and change the air in the polymerizer to react, reduce after the reaction Press out the water, which is stearyl maleate.

[0046]Step 2: Add 0.87kg of tert-butyl hydroperoxide to the polymerization kettle and stir, keep the reaction temperature at 170°C, after the polymerization reaction for 6 hours, discharge the polymer in the polymerization kettle, filter and remove impurities such as at a temperature above 100°C, It is stearyl alcohol maleate resin.

Abstract

The invention provides a butenedioic acid resin and a preparation method therefor, and degradable micro lubricating oil prepared through the butenedioic acid resin. The butenedioic acid resin is characterized by being prepared from the following substances comprising the following components: butenedioic acid or anhydride maleique, and fatty alcohol, wherein the molar ratio of the butenedioic acid or the anhydride maleique to the fatty alcohol is 1: (1.9-2); raw materials for preparing the degradable micro lubricating oil comprise the butenedioic acid resin. According to the degradable micro lubricating oil prepared by using butenedioic acid resin, a small quantity of the micro lubricating oil is used, so that the requirements of lubrication cooling, wear resistance under extreme pressure and rust prevention of metal processing can be met.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and relates to a butenedioic acid resin, a preparation method thereof, and a degradable micro-quantity lubricating oil prepared by using the resin. Background technique [0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators. . [0003] In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology has solved the above problems such as large amount of lubricant used and serious pollution, but the research on micro-quantity lubricant still has certain limitations in application. The problem is that the lub...
