Problems solved by technology

However, the cutting fluid on the 7075 aviation magnesium aluminum alloy currently on the market has several problems: easy to break force, scratches on the workpiece, easy odor of the cutting fluid, and easy corrosion of the workpiece, etc.
This type of products mainly foreign cutting fluid manufacturers control the domestic market, such as Castrol, Blaser and other foreign brands, their product prices are high, the cost of use is high, which seriously restricts the development of national industries

Embodiment 1

[0020] This example provides an aviation magnesium-aluminum alloy cutting fluid. Its raw materials include the following components by weight percentage: 35% mineral oil, 15% self-emulsifying ester (Priolube3955), 8% phosphate ester (Rhodia LB-400) , 5% monoethanolamine, 2% corrosion inhibitor (Lubrizol CP-NF-2), 8% sorbitan monooleate, 2% glycerol, 8% borate (Guangzhou Dexu Chemical DX6215 ), 3% isothiazolinone, 0.5% defoamer (Nanjing Sixin Technology X-35C) and the balance is water;

[0021] Its formulation includes the following steps: (a) adding the prescribed amount of water into the reactor, and starting the agitator; (b) sequentially adding the formulated amount of mineral oil, self-emulsifying ester, phosphoric acid ester, monoethanolamine, Corrosion inhibitor and sorbitan monooleate, stir for 1 hour; then add the formula amount of glycerin, borate, isothiazolinone and defoamer in sequence, continue to stir for 1 hour, add a raw material Stir to dissolve and then add ...

Embodiment 2

[0023] This example provides an aviation magnesium-aluminum alloy cutting fluid, the basic composition of which is basically the same as that in Example 1, the difference is that its content is inconsistent, specifically: 60% mineral oil, 10% self-emulsifying ester, 5% phosphate , 2% monoethanolamine, 1% corrosion inhibitor, 5% sorbitan monooleate, 0.5% glycerol, 5% borate (Guangzhou Dexu Chemical DX6215), 1% isothiazolinone, 0.1 % defoamer and balance water.

Embodiment 3

[0025] This example provides an aviation magnesium-aluminum alloy cutting fluid, the basic composition of which is basically the same as that in Example 1, the difference is that its content is inconsistent, specifically: 30% mineral oil, 20% self-emulsifying ester, 10% phosphoric acid ester , 5% monoethanolamine, 2% corrosion inhibitor, 10% sorbitan monooleate, 2% glycerol, 10% borate (Guangzhou Dexu Chemical DX6215), 5% isothiazolinone, 0.5 % defoamer and balance water.

Abstract

The invention relates to aviation magnalium cutting fluid and a preparation method thereof. The aviation magnalium cutting fluid comprises, by weight, 30-60% of mineral oil, 10-20% of self-emulsifying ester, 5-10% of phosphate, 2-5% of monoethanolamine, 1-2% of a corrosion inhibitor, 5-10% of sorbitan monooleate, 0.5-2% of glycerol, 5-10% of borate, 1-5% of isothiazolinone, 0.1-0.5% of a defoamer and the balance water. By precisely controlling the components and ingredients of the preparation, on the one hand, the service life of the cutting fluid and the service life of a cutter can be prolonged, the polarity lubricating effect of the cutting fluid is enhanced, machined magnalium is better in degree of finish, the product reject ratio is reduced to be 0.03% that in the prior art, the cost is reduced, and the production efficiency is improved; on the other hand, the self-emulsifying ester and the phosphate have the synergistic interaction effect in the extreme pressure lubricating aspect after being compounded, the extreme pressure lubricating performance of the product is remarkably improved, particularly, the phosphate can produce wonderful effects after being compounded with the corrosion inhibitor, the corrosion inhibitor additive amount is reduced, the cost of the cutting fluid is lower, and the product corrosion inhibition effect is better.

Description

technical field [0001] The invention relates to a cutting fluid, in particular to an aviation magnesium-aluminum alloy cutting fluid and a preparation method thereof. Background technique [0002] The main metal materials used in aircraft are aluminum alloy, alloy steel, titanium alloy, copper alloy and high-temperature alloy. Among them, aluminum alloy accounts for the largest proportion, accounting for about 75%. The main grades of aluminum alloy used are: 2024, 2124 , 6061, 7050, 7075, 7475, etc. Among them, the 7-series aluminum is aviation magnesium-aluminum alloy. Due to its excellent comprehensive properties such as good toughness, high fatigue strength, and good stress corrosion resistance, the proportion of use in aircraft manufacturing is increasing; among the 7-series magnesium-aluminum alloys, it is the most widely used. The most popular is 7075, which is an aluminum-zinc-magnesium-copper series heat-treatable and strengthened deformable aluminum alloy, mainly i...
