Abstract
In order to improve the lubricating property of the cutting fluid, the invention provides the cutting fluid with high lubricity, which comprises the following components in percentage by weight: 78-85% of base oil, 1-5% of molybdenum sulfide micron cage, 5-10% of animal and vegetable oil, 0.5-0.8% of antioxidant, 0.1-0.3% of antistatic agent and 5-9% of oily additive, wherein the total content of the components is 100%.
Description
Technical Field
The invention relates to the technical field of metal cutting processing.
Background
The cutting temperature in the metal cutting process is higher, the friction between the cutter and the metal workpiece is also larger, the cutter is easy to wear, and the workpiece is easy to thermally deform. The cutting fluid has the functions of cooling, lubricating, cleaning, rust prevention and the like, so that in the actual cutting process, the cutting fluid needs to be injected into a cutting machining area to reduce the temperature of the cutting machining area, reduce the friction between a cutter and a workpiece and the quality inspection of chips, clean chips generated by cutting, and inhibit the corrosion of the workpiece, the cutter, a machine tool, a clamp and the like caused by air, moisture, acid media and the like. In recent decades, along with the continuous improvement of cutting technology and continuous emergence of advanced cutting machine tools and continuous development of cutters and workpiece materials, the progress of cutting fluid technology is promoted. The consumption of the cutting fluid accounts for about 8% of the total consumption of the industrial lubricating oil. The traditional cutting fluid is divided into two major types of water-soluble cutting fluid and oil-soluble cutting fluid, the components of the cutting fluid mainly comprise base oil and additives, the formula is already mature after years of development, but with the development of a cutting process and the improvement of cutting equipment, particularly, the requirements on workpiece precision are continuously improved, and the water-soluble cutting fluid and the oil-soluble cutting fluid cannot completely meet the requirements of modern production, so that higher requirements are provided for the performances of the cutting fluid in the aspects of lubricating performance, heat exchange performance, permeability and the like.
Disclosure of Invention
In order to improve the lubricating property of the cutting fluid, the invention provides the cutting fluid with high lubricity, which comprises the following components in percentage by weight: 78-85% of base oil, 1-5% of molybdenum sulfide micron cage, 5-10% of animal and vegetable oil, 0.5-0.8% of antioxidant, 0.1-0.3% of antistatic agent and 5-9% of oily additive, wherein the total content of the components is 100%.
The molybdenum sulfide micro-cage is formed by assembling molybdenum sulfide particles, has a hollow spherical structure, has a porous surface, and contains stearic acid inside.
The molybdenum sulfide micro-cage diameter is about 1-3 microns.
The base oil is a low aromatic narrow fraction light mineral oil cut by distillation.
The animal and vegetable oil is one or more of pure rapeseed oil, epoxidized soybean oil, olive oil and de-esterified lard.
The antioxidant is di-tert-butyl-p-cresol (T501) and benzotriazole derivative (T551).
The oily additive synthesizes esters oil esters such as oleic acid esters, synthetic triol esters.
The preparation method of the high-lubrication cutting fluid comprises the following steps:
(1) The low aromatic hydrocarbon light mineral oil is distilled under reduced pressure, the head is pulled out, the light components are cut, and the flash point of the base oil is improved;
(2) Heating animal and vegetable oil to 65deg.C, slowly adding antioxidant to improve oxidation resistance of animal and vegetable oil, stirring to dissolve into uniform transparent, and maintaining at 60deg.C for 45-60 min;
(3) Adding molybdenum sulfide micro-cage into base oil, performing ultrasonic dispersion, adding the animal and vegetable oil, the antistatic agent and the oily additive obtained in the step (2), uniformly stirring at 65-70 ℃ to be transparent, and then continuously preserving heat and stirring for 45 minutes;
(4) Cooling the oil temperature to 45 ℃, and filtering the finished product.
The preparation method of the molybdenum sulfide micro-cage comprises the following steps: adding Cetyl Trimethyl Ammonium Bromide (CTAB) and stearic acid into a mixed solution of ethanol and water, and heating to fully dissolve the mixture to obtain a mixed solution A; dissolving ammonium dimolybdate in deionized water, adding thiourea, stirring until the ammonium dimolybdate is completely dissolved to obtain a mixed solution B, adding the mixed solution A into the mixed solution B, stirring and mixing uniformly to obtain a mixed solution C, pouring the mixed solution C into a hydrothermal kettle of a polytetrafluoroethylene inner container, performing hydrothermal reaction for 10-15h at 200-220 ℃, naturally cooling to room temperature, performing centrifugal separation, ultrasonically cleaning with deionized water and absolute ethyl alcohol for 3 times, and drying 8 h at 50-60 ℃ to obtain molybdenum sulfide micro cage particles.
Wherein, the mol ratio of ammonium dimolybdate to thiourea is 1:5-7, the mass concentration of CTAB in the mixed solution C is 0.1-0.5%, the mass concentration of stearic acid is 0.5-0.8%, the mass concentration of thiourea is 5-8%, and the volume ratio of ethanol to water is 1-2:1.
Advantageous effects
The molybdenum sulfide micro-cage is added into the cutting fluid and is assembled by molybdenum sulfide particles, the surface of the molybdenum sulfide micro-cage is of a hollow spherical structure, the surface of the molybdenum sulfide micro-cage is porous, stearic acid is contained in the molybdenum sulfide micro-cage, the spherical molybdenum sulfide micro-cage can play a role of a micro-steel ball at a friction interface in the cutting process, after the cutting process is stressed, the micro-cage is broken to generate nano-scale molybdenum sulfide particles, pits on the surface of a substrate are easy to fill, a compact lubrication protection film is formed, the spherical micro-cage and the spherical nano-particles can play a role of lubrication in a rolling friction mode, and when the molybdenum sulfide nano-particles are stressed further, friction between a cutter and a workpiece can be reduced in a sliding friction mode through the layered structure of the molybdenum sulfide. In addition, after the molybdenum sulfide micro-cage is crushed, stearic acid in the molybdenum sulfide micro-cage can be released, the stearic acid can be subjected to saponification reaction with the metal surface, an adsorption film is formed on the metal surface, the film forming capability of the cutting fluid is improved, and the lubricating performance of the cutting fluid is further improved.
