Embodiment

[0045] Take an ordinary water-based cutting fluid A, sample 1: add 0.5% aluminum corrosion inhibitor compound package 1 to water-based cutting fluid A, stir evenly; sample 2: add 0.5% ASI80 to water-based cutting fluid A, stir uniform. Sample 3: Add 0.6% to water-based cutting fluid A CP-NF-3, stir well; sample 4: add 0.3% ASI80 and 0.2% C101 to water-based cutting fluid A, stir well. Sample 5: Take 20.00% of ASI80, 26.67% of AR-80, and 53.33% of C101 and stir evenly to obtain Aluminum Corrosion Inhibitor Compound Package II. Add 0.5% Aluminum Corrosion Inhibitor Compound Package II to water-based cutting fluid A; Sample Five: Take 26.67% of ASI80, 53.33% of Lubrhophos LB-400, 20.00% of CP-NF-3 was stirred evenly to obtain the aluminum corrosion inhibition compound package III, and 0.5% aluminum corrosion inhibition compound package III was added to the water-based cutting fluid A.

Abstract

The invention provides a composite corrosion inhibitor for an aqueous cutting fluid, which includes, by weight, 24-29.34% of a metal corrosion inhibitor, 48-58.66% of a surfactant and 18-22% of siloxane, wherein the trade mark of the metal corrosion inhibitor is Rhodafac ASI80; the trade mark of the surfactant is Shanghai Isa-chem AR-80 fatty alcohol-polyoxyethylene ether phosphate surfactant; and the trade mark of the siloxane is Horlt Chemical C101. The invention also provides a preparation method of the composite corrosion inhibitor for the aqueous cutting fluid and the aqueous cutting fluid. Compared with the prior art, the composite corrosion inhibitor can reduce cost and improve protective performance of the cutting fluid on aluminum alloy and solves a problem of incompatibility with the cutting fluid. The compounded metal corrosion inhibitor has a wider available temperature range.

Description

technical field [0001] The invention relates to the field of water-based cutting fluid, in particular to a composite corrosion inhibitor for water-based cutting fluid, a preparation method and the water-based cutting fluid. Background technique [0002] During the use of cutting fluid, it mainly has the functions of cooling, anti-rust and anti-corrosion, lubrication and cleaning. In the process of metal processing, the surface of the workpiece after processing is the new surface of the metal material, which is chemically active and prone to oxidation. In addition, there are many causes of metal corrosion: minerals and salts in diluted water will cause metal corrosion. In addition, as the cutting fluid is used for a long time, the salt in the fluid will accumulate until it reaches a maximum value, and the metal will Corrosion will also become worse; the workpiece in the use of liquid or after processing, if there is contact with different metals, electrochemical corrosion wi...
