3Represent the fatty acid chain of identical or different carbonatoms, it can be saturated and fatty acid chain undersaturated carbonatoms, through emulsion reaction low layer water-soluble be to belong to undersaturated those fatty acid chains, its and part are added the water-soluble base oil that tensio-active agent that side reaction that advance and a small amount of generates has formed bottom.Thereby finished the transformation from the oiliness to the water-based, can satisfy the needs of metal-processing industry lubricated, cooling, antirust and cleaning etc.
(1) the upper strata oiliness of manufacturing of the present invention and lower floor's water-based all have good lubricated and cooling performance.
Plant oil based lubricant is the product based on plant.Their moiety can satisfy special processing property and require and technical requirements through refining.By the composite lubricating film layer that vegetables oil provides, its intensity height, lubricity is good.Therefore, the lubricity of this class cooling fluid is much higher than other mineral oil.In addition, plant oil based product has more effective and more competent lubricity than other alternative cooling fluids.Even the processing of material requirements heavy cutting, the plant oil based cooling fluid of using also need not add EP (anti-high pressure) additive.Adopt the lubricant of vegetables oil technology, its price is than substitute products height.In order to improve its biological stability, need the more expensive composition of interpolation expense.But, to compare with alternative lubricant, its extra expense that increases can be by boosting productivity and being offset by other various methods that reduce cost.
The high lubricating property of vegetables oil is determined by the basal component of vegetables oil molecule and the chemical structure of itself.Based on the cooling fluid of vegetables oil, its lubricity results from intrinsic " oiliness " of vegetables oil composition, and this specific character is the result who is directly caused by vegetables oil " clever molecule ".This quasi-molecule is very long, and is very heavy, has bipolarity, that is: the two ends of molecule have opposite electric charge.Two " extremely " of molecule have very strong chemical affinity to the metallic surface, and they are adsorbed on the metallic surface tightly as small magnet.The vegetables oil molecule is arranged on the metallic surface vertically, closely, equably, and the result forms thick, solid, the competent composite lubricating film of one deck on its surface.The blocky composite lubricating film of this layer improved the ability of vegetables oil absorption pressure.
On the contrary, the molecule of mineral oil is not to be with polar.Their arranged evenly on the metallic surface are irregular, and therefore the lubricant film that is produced is relatively weaker.The viscosity index of vegetables oil is high more, just can guarantee the lubricating property that it is stable in operating temperature range more.Along with the raising of processing temperature, the viscosity drop low rate of vegetables oil is slower than mineral oil.On the contrary, along with the reduction of temperature, the liquid fluidity of vegetables oil is better than mineral oil, helps separating with workpiece with smear metal.And its fusing point is higher, helps improving metal removal rate, reduces the formation of smog, reduces the danger of presence of fire.
The vegetables oil bulk of molecule is very even, and mineral oil bulk of molecule variation range is very big.Therefore, the physical property of mineral oil, for example its in when evaporation and the viscosity when reaching boiling point be subjected to very big influence.The higher of vegetables oil and big weight make it extremely low because of the loss of evaporating and atomizing causes.Because its molecular wt is higher, its sediment is limited in the small range.Can be the Working environment that people build health and cleaning like this, airborne smog reduces in a large number, and vegetables oil can not produce any toxic side effect to environment.
Through experiment, adopt the vegetables oil technology, have sizable superiority cutter life to boosting productivity and improving.In the course of processing, adopt plant oil based cooling fluid can improve the smooth finish and the tolerance of dimension of finished surface, improve complete processing level, ability and boost productivity.For example, add man-hour in that automobile gear is carried out drilling, adopt plant oil based cooling fluid after, can make improve 3 times the work-ing life of drill bit.In addition, when producing titanium metal and stainless steel medical treatment implantation piece, after the employing vegetables oil technology, make output improve 10%, also make the cutter expense reduce by 50% simultaneously.Also have an example more can say something: in the automotive industry Application Areas, adopt plant oil based cooling fluid after, make the screw tap of machined steel workpieces improve 15 times work-ing life.
In the machining Application Areas, alien crop oil base cooling fluid can make the mechanical cutting performance improve comprehensively.As a technology through practical proof, since the sixties in 20th century, vegetables oil is considered to have super always.Based on the lubricating fluid of vegetables oil, demonstrated the lubricating fluid that its processing characteristics is better than mineral oil and synthesizing formula greatly in the major applications field.These superiority-process-cycle shortens, changes trouble-free operation prolongation pitch time between the cutter, the quality raising-major part of workpiece should give the credit to the use of plant oil based metal working lubricant liquid and higher lubricity thereof.Adopt plant oil based cooling fluid in complete processing, productivity can improve 20%～30%, and can improve more than 50% the work-ing life of cutter.Therefore, no matter be the oil in water emulsion of upper strata fatty acids glyceryl ester or the fatty acids ethanol ester of bottom, its oilness and cooling property all are justifiable.
(2) upper strata of manufacturing of the present invention and bottom lubricant all have good cleaning.
The present invention crosses the emulsification of heating by the adding tensio-active agent to the vegetables oil back warp to form oil in water emulsion, thereby its surface tension descends, and the nonionogenic tenside itself that adds has hydrophilic and lipophilic group, as 6501 (the Fatty Alcohol(C12-C14 and C12-C18) alkylolamides) that add, cleaning performance own is just good, degreasing power is strong, and is the major ingredient of preparation industrial cleaning agent.Thereby this lubricant has fabulous cleaning performance.
(3) except that above-mentioned functions, also has antirust function preferably.The additive urea, 6501 (Fatty Alcohol(C12-C14 and C12-C18) alkylolamide) that joins in the vegetables oil itself is exactly good rust-preventive agent, and ferrous metal is had stronger antirust function.
(4) aftertreatment is easy, and is non-stimulated to human body skin.The protection human body, environmental safety.
According to the above-mentioned upper strata oily lubricant of producing, as metal processing drawing oil usefulness, its physicals leading indicator is as follows:
The water-based lubricant of bottom after 20 times of dilutions, meets the GB3392/T standard-required, and its leading indicator is as follows:
