Description
Technical Field
The invention belongs to the field of metal working fluids, and particularly relates to a high-performance fully-synthetic water-based metal working fluid.
Background
The metal surface is subjected to a large cutting force during machining and has a relative movement, so that a large friction is generated between the tool and the workpiece surface, and between the tool and the chip. The presence of such friction phenomena generates a large amount of heat and aggravates wear of the tool and deterioration of the workpiece surface accuracy, and reduces the machining efficiency. In addition, the dual functions of shearing and friction exist in the machining process, so that larger heat is inevitably generated, if the heat cannot be taken away in time, high temperature is generated between the cutter and the workpiece, the cutter is softened, the hardness of the surface of the workpiece is even reduced, the cutter abrasion is increased, and the surface precision of the workpiece is affected. Moreover, accumulation of chips can be generated at high temperature, so that the machining precision of the workpiece is deviated. Machining chips generated during metal machining, if not removed from the machining area in time, may generate built-up chips and cause abrasion of the machined surface. Most metallic materials (e.g., iron and cast iron) rust quickly after contact with humid air and water, resulting in product rejection.
The metal working fluid mainly plays roles of lubrication and cooling, has the functions of rust prevention, cleaning and the like, so that friction is reduced, heat generated in a machining process can be taken away through the flushing function of the large-flow metal working fluid, and a good rust prevention function can be provided, so that the temperature of a cutter and a workpiece is reduced, the service life of the cutter is prolonged, the surface precision of a machined part is improved, and the machining efficiency is improved.
At present, many total synthetic metal working fluids in China are weak in rust prevention and lubrication, contain an environment-friendly carcinogenic substance nitrite, bring unnecessary economic loss to enterprise production, and bring a lot of hidden troubles to social environment. In addition, the metal working fluid has poor performance, so that large-scale equipment or some precise equipment is damaged, and serious economic loss is caused for enterprises.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a high-performance fully-synthetic metal working fluid which consists of an antirust agent, an oiliness agent surfactant, a synthetic lubricant and the like and is specially designed for imported and domestic high-precision machining center equipment requiring high lubrication, cooling, cleaning and corrosion resistance.
In order to achieve the above purpose, the invention adopts the following technical scheme:
the aqueous metal working fluid consists of the following components in percentage by mass:
13.5 to 16.0 percent of pH regulator
4.1 to 5.3 percent of rust inhibitor
Complexing agent 0.1-0.3%
4.0 to 5.0 percent of oiliness agent
0.1 to 0.3 percent of defoaming agent
0.001 to 0.003 percent of colorant
The balance being water.
The pH regulator is prepared from monoethanolamine, triethanolamine and potassium hydroxide according to a mass ratio of 3.0-4.0: 10.0 to 11.0:0.5 to 1.0, and is used for adjusting the pH value of the aqueous processing liquid to 10 to 11.
The antirust agent is prepared from benzotriazole and boric acid according to the mass ratio of 0.1-0.3: 4.0 to 5.0.
The complexing agent is ethylenediamine tetraacetic acid.
The oily agent is vegetable oleic acid.
The defoaming agent is organic silicon.
The colorant is dye, the color of the metal processing liquid is regulated and controlled by strictly controlling and monitoring the adding proportion of the dye, and the concentration of the colorant is judged by the color of the processing liquid in use, so that the colorant is important to control the quality of products.
The invention also provides a preparation method of the aqueous metal working fluid, which comprises the following steps: mixing pH regulator, antirust agent and complexing agent, heating to 70deg.C, stirring and mixing to transparency, adding oily agent and stirring to transparency, adding defoamer, colorant and water, stirring to transparency, cooling to normal temperature, and packaging.
The specific gravity of the aqueous metal working fluid stock solution prepared by the method is 1.0-1.1 g/cm 3 (20 ℃) and a dynamic viscosity of 1.1 to 1.4mm 2 The copper plate corrosion was classified into 1a to 1b (100 ℃ C..times.3. 3 Hrs).
The aqueous metal working fluid is diluted and used for metal working, the concentration is generally 3-6%, and if special working requirements are met, the concentration can be properly increased. The preparation method comprises the following steps: the tap water is directly prepared by industrial tap water (for obtaining the best use performance, the recommended water hardness range is 50-150 ppm), and when the tap water is prepared, the tap water is firstly added into a liquid tank, and then the concentrated solution is added to the specified concentration while stirring (or beating and circulating) for recycling.
The aqueous metal working fluid of the present invention is suitable for the general cutting and grinding of cast iron, ferrous metals including stainless steel, ceramics, nichrome and the like, and is a dual-purpose synthetic water-soluble cutting oil. The processing equipment is an internal and external grinding machine, a plane, a centerless, a channel, a guide rail, a high-speed grinding machine, a lathe, a drilling machine, a milling machine and the like. The grinding machine is particularly suitable for grinding the bearing ring.
Compared with the prior art, the invention has the beneficial effects that: the lubricating performance is good, the service life of the cutting tool is prolonged, the abrasion in the processing process can be effectively reduced, and the surface smoothness of the workpiece is improved. The cooling performance is excellent, the cutting heat is fully taken away, the surface of the workpiece has strong adsorption capacity, and the workpiece is not annealed and burnt. Excellent corrosion resistance and excellent protection for the workpiece. Has good antistatic property and permeability, and has no bonding phenomenon to the grinding wheel. Safe and environment-friendly, long in service life and capable of being recycled for a long time. The method is particularly suitable for rough grinding of the bearing.
