Problems solved by technology

[0003] Cutting fluids include mineral-based and water-based types. Although mineral-based cutting fluids have the advantage of good lubricating properties, the lubricating properties of mineral-based cutting fluids will decrease rapidly as the temperature increases during the cutting process.
In addition, mineral-based lubricating oil has poor biodegradability in the natural environment. It will exist in the environment for a long time and eventually enrich it, which will cause environmental pollution, and it contains certain toxic or pungent odor substances, which are harmful to the human body.
Although water-based cutting fluid has the advantages of excellent cooling, cleaning, environmental protection and safety, it has the problem of poor lubricating performance.

Abstract

The invention discloses a low-cost titanium alloy water-based cutting fluid based on black phosphorus quantum dots and a preparation method of the low-cost titanium alloy water-based cutting fluid. The cutting fluid comprises the following components in parts by weight: 0.02-0.1 part of black phosphorus quantum dots, 0.2-1.5 parts of nano oxide, 2-7 parts of a dispersing agent, 3-5 parts of a binder, 1-2 parts of an extreme pressure agent, 1-3 parts of an antirust agent, 3-6 parts of an antioxidant and 75.4-89.8 parts of deionized water. The preparation method comprises the steps of adding the dispersing agent, the binder, the antirust agent and the extreme pressure agent into the deionized water, stirring on a temperature-controlled magnetic stirrer until all the raw materials are completely dissolved, adding the black phosphorus quantum dot aqueous solution when the temperature rises to 80-100 DEG C, stirring at a constant temperature, adding the nano oxide when the temperature rises to 120-150 DEG C, stirring at a constant temperature for 60-90 minutes, adding the antioxidant, stirring for 10-15 minutes, carrying out water bath ultrasonic treatment for 90-120 minutes, and finally adjusting the pH value to 8-10 to obtain the target product. The cutting fluid has proper viscosity, excellent uniformity, stability, rust and corrosion resistance, high-temperature friction performance and good antifriction performance, and is suitable for titanium alloy processing.

Description

technical field [0001] The invention belongs to the technical field of mechanical lubrication, and in particular relates to a low-cost titanium alloy water-based cutting fluid based on black phosphorus quantum dots and a preparation method thereof. Background technique [0002] Titanium alloy has high strength, excellent mechanical properties and good corrosion resistance, making it an ideal material for aircraft and engines in aerospace, but the poor machinability of titanium alloy greatly restricts the application of titanium alloy. Due to the poor thermal conductivity of titanium alloys, the heat generated during the cutting process will not be quickly transferred to the workpiece or taken away by the chips. The temperature generated in the cutting area is as high as 1000 ° C, causing the cutting edge of the tool to wear rapidly, crack and generate built-up edge. , the rapidly worn blade will generate more heat in the cutting area, further shortening the life of the tool;...
