Embodiment 1

[0038] Step 1: Weigh 92.09kg (1000mol) of glycerin and 82kg (1000mol) of phosphorous acid into the reaction kettle, fill it with nitrogen protection, heat and stir to 130°C, keep stirring at constant temperature for 4 hours, discharge the water generated by the reaction under reduced pressure, and prepare phosphorous acid Glyceride A 142kg (1000mol) for standby (the yield of the product in actual production is less than 100%, so the actual obtained phosphite glyceride is less than 1000mol);

[0039] Step 2: Add 142kg (1000mol) of phosphite glyceride A and 5.15kg of potassium hydroxide prepared in step 1 into the polymerization kettle cooled by ice-salt water circulation at about 0°C and stir, then pass into the polymerization kettle into the nitrogen conversion kettle Air, when the nitrogen in the polymerization kettle maintains a positive pressure, use a nitrogen feed tank to push 881kg (20000mol) of ethylene oxide into the polymerization kettle, while stirring to raise the te...

Abstract

The invention provides a polyoxyethane ether-based glycerol phosphite polymer, a preparation method for the same and a near-dry cutting fluid prepared from the same for gear machining. The polymer has a chemical formula as described in the specification, and n in the chemical formula is an integer in a range of 10 to 20. The preparation method for the polymer comprises the following steps: reacting glycerin and phosphorous acid according to a mol ratio of 1:1 to obtain glycerol phosphite; and subjecting glycerol phosphite and ethylene oxide in a ratio of 1: (10-20) to polymerization. The near-dry cutting fluid for gear machining comprises, by weight, 40 to 70% of the polyoxyethane ether-based glycerol phosphite polymer (containing polyoxyethane glyceryl ether, potassium phosphite and potassium hydroxide) and 2 to 3% of potassium tetraborate, with the balance being deionized water. The near-dry cutting fluid for gear machining provided by the invention has excellent cooling and lubricating performances and good anti-abrasion and anti-rust properties; when used together with a near-dry cutting lubricating device, the application amount of a lubricant is reduced to less than 5%, so energy saving and environmental protection are realized.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a polyoxyethylene ether-based phosphite glyceride polymer, a preparation method thereof, and a quasi-dry cutting fluid for gear processing prepared by the polymer. Background technique [0002] Traditional gear processing uses a large amount of mechanical oil for shower lubrication. The amount of lubricant used is large, which not only wastes resources, causes huge pollution to the processing site and the environment, but also seriously affects the health of operators. Today, when energy conservation, emission reduction, environmental protection, and green production are advocated, a new gear processing technology is urgently needed. Gear machining quasi-dry cutting technology is a new gear cutting technology developed in recent years. It uses quasi-dry lubrication system for lubrication during gear cutting. The development of this technology requires a gear ...
