Description
Technical Field
The invention relates to a grinding fluid, in particular to a steel ball oil-based primary grinding fluid and a preparation method thereof, belonging to the technical field of grinding fluids and preparation thereof.
Background
Grinding fluids are industrial fluids used to cool and lubricate tools and workpieces during metal grinding processes and are generally classified into oil-based grinding fluids and water-based grinding fluids. The oil-based grinding fluid contains base oil, an oiliness agent, an extreme pressure additive and other additives, has excellent lubricity and rust prevention, but has poor cooling effect and is not easy to clean. The water-based grinding fluid is usually composed of chemical agents such as emulsion, surfactant and the like and water, and has good cooling property and cleaning property, but the lubricating property and the rust-proof property are far inferior to those of the oil-based grinding fluid. Along with the development of the mechanical industry to the directions of rapidness, strength and precision, and in order to meet the processing requirements of various super-hard and super-strong new materials which are continuously developed, the requirements of the mechanical industry on a grinding process are continuously improved, so that the traditional oil-based grinding fluid and water-based grinding fluid can not meet the requirements any more, and a novel grinding fluid with the advantages of the water-based grinding fluid and the oil-based grinding fluid is required.
The steel ball is one of the important components of the ball bearing and is formed by mechanically cold heading and grinding the raw material of the steel wire. The processing technological process of the steel ball comprises cold heading, polishing, heat treatment, hard grinding, primary grinding and fine grinding. The grinding process of the steel ball is different from the common workpiece processing and grinding process, and the steel ball grinding is completed by revolution of a roller path of a grinding disc template and rotation of the steel ball under certain extrusion pressure, so that the steel ball can be continuously polished, rounded and polished, and is not common clamping grinding.
Disclosure of Invention
The invention aims at the defects of the prior art, namely the defects that the oil-based grinding fluid has good lubricity but poor cooling property and is difficult to clean, and the water-based grinding fluid has poor lubricity and rust resistance and is easily influenced by bacteria. The grinding fluid special for the steel ball is obtained by combining the process characteristics of grinding the steel ball, controlling the types of the additives and carrying out proportion control, and solving the organic coordination of a plurality of influencing factors influencing the grinding process and the grinding quality of the steel ball.
The technical scheme for solving the technical problems is as follows: a steel ball grinding fluid comprises the following components in parts by mass:
85-94 parts of aviation kerosene;
1-5 parts of rosin powder;
5-10 parts of an organic antirust agent;
1-3 parts of an inorganic antirust agent;
2-6 parts of triethanolamine;
0.08-0.12 part of white corundum.
Further, in the above-mentioned case,
88-92 parts of aviation kerosene;
2-3 parts of rosin powder;
7.5-8.5 parts of an organic antirust agent;
1.2-2.5 parts of an inorganic antirust agent;
3.5-4.4 parts of triethanolamine;
0.1-0.11 part of white corundum.
Further, the organic antirust agent is one or two of benzotriazole or sebacic acid, and benzotriazole is preferred.
Further, the inorganic antirust agent is one or two of borax and sodium dodecaphosphomolybdate, and borax is preferred.
Furthermore, the grain diameter of the white corundum is 2.0-2.5 um. The particle size is suitable, the proper grinding effect is achieved, and the sedimentation is not easy to occur.
Preferably, the steel ball grinding fluid comprises the following components in parts by mass:
90 parts of aviation kerosene;
2 parts of rosin powder;
8 parts of benzotriazole;
2 parts of borax;
4 parts of triethanolamine;
0.1 part of white corundum.
The preparation method of the steel ball grinding fluid comprises the steps of mixing aviation kerosene, rosin powder, an antirust agent, borax, triethanolamine and white corundum according to the components in parts by mass, controlling the temperature of a reaction kettle to be 25 +/-5 ℃, controlling the stirring to be 10-20 revolutions per minute, and controlling the stirring time to be 30 +/-10 minutes, thus obtaining the steel ball grinding fluid.
The steel ball grinding fluid of the invention has the following functions and synergistic effects:
(1) Aviation kerosene, which has a long service life due to its efficient sterilization system; good abrasion resistance, low foaming; is suitable for hard water and soft water, and is beneficial to prolonging the service life of the tool; the smell is mild and can be accepted by most operators; the viscosity and the lubricating property are good.
(2) The white corundum works at high speed, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, inner circle, plane, various molded surfaces and the like of a metal or nonmetal workpiece. The prior steel ball grinding technology usually adopts water-based grinding fluid, namely lapping fluid. White corundum particle abrasive micro powder is dissolved in lapping liquid, and is very easy to precipitate to the bottom of an abrasive box because the white corundum particle abrasive micro powder is difficult to dissolve in water, and particles which are washed on the surface of a steel ball are few, so that the grinding time of the steel ball is too long, waste is caused, and the efficiency is low. The grinding fluid has certain viscosity, so that the white corundum can be well suspended and is not easy to settle.
(3) The rosin powder mainly contains rosin acid, has no harm to human body, and is dissolved in aviation kerosene in the grinding fluid. During the grinding process, a large amount of heat is generated, the rosin powder is melted after absorbing the heat and fully permeates into fine lines on the surface of the steel ball with higher temperature, and the fine lines have certain film forming property, so that the rosin powder has a certain waterproof effect, and the viscosity is increased. However, the amount of the binder should not be too large or too small, and when the amount is too small, the use effect is not good, and when the amount is too large, the binding effect is too large.
(4) The organic antirust agent, benzotriazole, is dissolved in the grinding fluid, and an emulsifier is not required to be added when the grinding fluid is used, so that the side effect derived from the addition of benzotriazole is greatly reduced, and the grinding fluid is more convenient to clean.
(5) The inorganic antirust agent, such as borax, has the functions of rust prevention, bacteriostasis, extreme pressure, thickening and the like in the grinding fluid.
(6) The triethanolamine can effectively prevent rusting in a short time. The additive with a proper amount has a synergistic anti-rust effect with an organic anti-rust agent, such as benzotriazole, and has a good synergistic anti-wear effect with aviation kerosene and borax. The triethanolamine in the grinding fluid can be helpful for the grinding fluid to infiltrate into the ground interface, thereby playing the roles of cooling and cleaning the grinding fluid.
In conclusion, the invention has the following beneficial effects: the steel ball grinding fluid has certain viscosity, good lubricating property, high cooling speed, good rust resistance and easy cleaning; the white corundum micro-powder particles are not easy to precipitate in the grinding fluid, and the surface of the steel ball can be repeatedly washed, so that the grinding time of the steel ball is greatly saved, the grinding efficiency of the steel ball is improved, and the production cost is reduced. The oil-based grinding fluid forms a lubricating film, so that the friction of an interface is reduced, the friction abrasion and adhesion of a grinding wheel are prevented, the service life of the grinding wheel is prolonged, and compared with a water-based grinding fluid, the oil-based grinding fluid can better prevent the roughness of the surface of a steel ball from deteriorating. The preparation method of the steel ball grinding fluid provided by the invention is simple to operate, requires low temperature and is suitable for industrial production.
