Description
Technical field
The invention belongs to metal manufacture field, especially relate to the synthetic grinding fluid of a kind of environmental protection.
Background technology
In mechanical equipment manufacture process, the working method kind of metal is a lot.Wherein machining is the most common, most widely used a kind of processing mode in metal processing.
Metal cutting processing provides under the condition of power at lathe with exactlying, by cutter, the excess metal of metal works partly cut, thus the shape, size, precision and the surface quality that workpiece are obtained stipulate satisfactory a kind of course of processing all.By different processing modes, can be divided into car, milling, brill, plane, boring, expansion, hinge, broaching, tapping, Gear Processing ... and the multiple processing mode such as ground finish.
Grinding is the larger processing mode of a kind of amount of finish in metal cutting processing mode.It is that with the different place of general cutting the instrument of ground finish is not the cutter with sword, but cuts with emery wheel.
In metal removal process, due to the high speed rotating of emery wheel, the linear velocity of machining is very fast, and fricative heat surpasses general machining, and grinding temperature can surpass more than 1000 ℃.For Cooling and Lubricator emery wheel and workpiece, ground finish is normally carried out, must use grinding lubricant to take away in time the heat that grinding produces, reduce the temperature of emery wheel and workpiece, and play good lubrication, improve workpiece surface finish, reduce the wearing and tearing of emery wheel, extend emery wheel work-ing life.This grinding lubricant is just grinding coolant, is also grinding fluid.
In Grinding Process, except selecting suitable processing units-grinding machine, reasonably select beyond best grinding process, well behaved emery wheel, select suitable grinding fluid also to play an important role.Therefore, the grinding fluid product that quality bills of materials is good, also becomes a general important problem.
Metallurgical roller is the visual plant of producing various priming sheets, and even in order to guarantee steel-sheet thin and thick, surfacing is smooth, and roller surface need to often carry out grinding arrangement.Iron And Steel Industry is mainstay of the national economy industry, China Shi Chan steel big country.Therefore, roll dressing technique needs a large amount of high-quality grinding fluids supporting with it.Metallurgical roller is nickeliferous cold hard cast-iron, and its surface hardness is high, gets rusty easily again.Therefore, with plain grinding liquid, add man-hour, often occur following problem:
1. poor lubricity.Poor surface smoothness after grinding, abrasion of grinding wheel is serious, and emery wheel life cycle is short.Affect grinding efficiency, increase production cost.
2. rust-preventing characteristic is poor.Roll duration of service after grinding, length will not got rusty, and summer high temperature high humidity is more obvious season.Because appearance is got rusty, outward appearance is brightless, beautiful yet.
Summary of the invention
The problem to be solved in the present invention is to provide the synthetic grinding fluid of a kind of environmental protection, this grinding fluid possesses good lubricated, cooling, cleaning, antirust function, can reduce to greatest extent grinding temperature and grinding force, the rust resistance and corrosion resistance that guarantee workpiece grinding accuracy and surface quality, prolongation emery wheel work-ing life, improve grinding efficiency, meets lathe and workpiece requires, reduces use cost, meet environmental requirement, is especially suitable in the metallurgical roller in steel industry.
For solving the problems of the technologies described above, the technical solution used in the present invention is: grinding fluid is synthesized in a kind of environmental protection, and it is made by following component by weight percentage:
Oleic acid 2.5%, trolamine 5%, sebacic acid 2%, trolamine 4%, Sodium Benzoate 2%, polyethers 4.5%, polyoxyethylene glycol 5%, sodium carbonate 2%, ammonium molybdate 1%, glycerine 4%, benzotriazole 0.2%, defoamer 0.2%, isothiazolinone 0.6%, fluorescence green 0.03%, deionized water 66.97%;
Its preparation method comprises the steps:
(1) oleic acid of use calculated amount and trolamine, first in reaction kettle for reaction, under 100 revs/min of continuously stirring, are heated to 50～60 ℃, continue to stir 30 minutes, standby;
(2) deionized water of calculated amount, sebacic acid, trolamine are added in another reactor successively, start agitator, with 100 revs/min, stir at normal temperatures 1 hour;
(3) under continuously stirring, again the triethanolamine oleate of the Sodium Benzoate of calculated amount, polyethers, polyoxyethylene glycol, sodium carbonate, ammonium molybdate, glycerine, benzotriazole, defoamer, isothiazolinone, fluorescence green and step (1) gained is added in the reactor in step (2) successively, be heated to 50～60 ℃, continue to stir 1 hour;
(4) be down to normal temperature, obtain the synthetic grinding fluid of described environmental protection.
Compared with the existing technology, tool has the following advantages in the present invention:
1. the present invention has better lubricity.The lubricated active substance that the present invention is contained, has larger avidity to metallic surface, and the polar group of its polar molecule has stronger chemisorption and physisorption to metallic surface.Can between metal and emery wheel, form firmly boundary lubrication layer by rapid permeability, reach better lubricant effect, reduce friction and bonding, reduce grinding heat and grinding force, thereby improve the smooth finish of roller surface.
2. the working fluid obtaining with grinding fluid dilution of the present invention, has better cooling performance, and lower grinding temperature, reduces the thermal distortion of emery wheel and roller surface rapidly, keeps Wheel hardness, improves working accuracy and emery wheel durability, extends emery wheel life cycle.
3. the present invention has better rustless property, has guaranteed the rust resistance and corrosion resistance requirement to lathe and roll.Roller surface after original grinding easily gets rusty and corrodes, and rusty stain and corrosion spot have reduced the roller surface quality being ground.Roll after grinding of the present invention is difficult for getting rusty and corroding.Keep for a long time roller surface light as new, thereby guaranteed the surface quality of roller surface after grinding.
The present invention long-term store and use procedure in be difficult for putrid and deteriorated, nontoxic to operator, environmentally safe, life cycle is longer, further reduces use cost.
