Problems solved by technology

[0002] The traditional aluminum alloy 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 operators. healthy

Embodiment 1

[0042] Step 1: Weigh 124.136kg (2000mol) of ethylene glycol and 61.83kg (1000mol) of boric acid into the reaction kettle, fill it with nitrogen protection, heat and stir to 180°C, keep stirring at a constant temperature for 4 hours, depressurize and discharge the water generated by the reaction, and prepare two Ethylene glycol borate for use;

[0043] Step 2: take by weighing the diethylene glycol borate ester 138kg (1000mol) that step 1 reacts to generate and the octanoic acid of 144.24kg is put into reactor, then add the strongly acidic cation exchange resin of 5kg (001×7 strongly acidic styrene series cation exchange resin) as a catalyst, filled with nitrogen for protection, stirred and heated to 200°C, kept stirring at a constant temperature for 4 hours, decompressed and discharged the water generated by the reaction, and removed the cation exchange resin to obtain diethylene glycol octanoic acid borate (containing a small amount of ethyl diol dicaprylate and boric acid); ...

Embodiment 2

[0050] Step 1: Weigh 124.136kg (2000mol) of ethylene glycol and 98kg (1000mol) of phosphoric acid into the reactor, fill it with nitrogen protection, heat and stir to 110°C, keep stirring at a constant temperature for about 3 hours, depressurize and discharge the water generated by the reaction, and prepare two Ethylene glycol phosphate spare;

[0051]Step 2: Take 174kg (1000mol) of diethylene glycol phosphate produced by the reaction in step 1 and add it to the reactor, weigh 200.32kg (1000mol) of lauric acid and add it to the reactor for mixing and stirring, and then add 7kg of strong acidic cation exchange resin (D001 macroporous strongly acidic styrene-based cation exchange resin) as a catalyst, filled with nitrogen protection, stirred and heated to 220 ° C, kept stirring at a constant temperature for 3 hours, decompressed to discharge the water generated by the reaction, and removed the cation exchange resin to obtain diethyl ether Glycol laurate phosphate (contains small...

Embodiment 3

[0058] Step 1: Weigh 124.136kg (2000mol) of ethylene glycol and 61.83kg (1000mol) of boric acid into the reaction kettle, fill it with nitrogen protection, heat and stir to 160°C, keep stirring at a constant temperature for 4.5 hours, depressurize and discharge the water generated by the reaction, and prepare two Ethylene glycol borate for use;

[0059] Step 2: take by weighing the diethylene glycol borate ester 138kg (1000mol) that step 1 reacts and generate and the decanoic acid of 172.27kg (1000mol) is put into reactor, then add the strongly acidic cation exchange resin of 5kg (001×7 strongly acidic Styrene-based cation-exchange resin) as a catalyst, filled with nitrogen protection, stirred and heated to 220 ° C, kept stirring at a constant temperature for 3 hours, decompressed and discharged the water generated by the reaction, and removed the cation-exchange resin to obtain diethylene glycol decanoic acid boric acid Esters (contains small amounts of ethylene glycol dideca...

Abstract

The invention provides a near-dry cutting oil for aluminum alloy and a preparation method thereof. The near-dry cutting oil for aluminum alloy comprises, by weight, 20 to 80% of diethylene glycol carboxylic borate (containing a small amount of glycol dicarboxylate and boric acid) and 20 to 80% of diethylene glycol carboxylic phosphate (containing a small amount of glycol dicarboxylate and phosphoric acid). The preparation method for the aluminum alloy near-dry cutting oil is to uniformly mix diethylene glycol carboxylic borate (containing a small amount of glycol dicarboxylate and boric acid) and diethylene glycol carboxylic phosphate (containing a small amount of glycol dicarboxylate and phosphoric acid) in proportion under stirring so as to prepare the near-dry cutting oil for aluminum alloy. The near-dry cutting oil for aluminum alloy provided by the invention has excellent extreme pressure properties, abrasion resistance and lubricity; when the cutting oil is used together with a near-dry cutting lubricating device, no smoke is generated in the process of near-dry machining of aluminum alloy, the application amount of the cutting oil is reduced to less than 5% of the application amount of original cutting oil, and good energy saving and environmental protection effects are realized.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to an aluminum alloy quasi-dry cutting oil and a preparation method thereof. Background technique [0002] The traditional aluminum alloy 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. healthy. Today, when energy conservation, emission reduction, environmental protection, and green production are advocated, a new aluminum alloy cutting process is urgently needed. Quasi-dry cutting technology is a new technology for aluminum alloy cutting developed in recent years, which is to use quasi-dry lubrication system for lubrication during aluminum alloy cutting process. The development of this technology requ...
