The comparison of ingredients of water-base cutting fluid is complicated, this is because will take the stable of emulsifying system into account, should consider the HLB value of all compositions, reach the balance of properties again.Because cutting fluid is matrix with water, the character also should considered the water-soluble of all compositions or disperse in water.
In metal cutting process, great majority friction belongs to boundary lubrication friction.In boundary lubrication, owing to there is not oil film completely, its supporting capacity has nothing to do with oil viscosity, and depends on the oiliness of lubricating fluid, and namely whether Lubrication Composition contains atomic group metal being existed to strong adsorption, can form physics adsorption film at cutting interface.
Polar group during nonionogenic tenside lipid acid sorb is smooth has larger affinity ability to metal, is easy to absorption on the metal surface, forms adsorbed lubricating film.Because its hydrophobic grouping is comparatively large, and there is aromatic ring structure, there is the effect of oiliness improver.Nonionogenic tenside lipid acid sorb is smooth containing the nonactive extreme pressure element of N simultaneously, and it has the double effects of oiliness improver and extreme pressure agent concurrently.Act synergistically with the extreme pressure anti-wear additives added again, form high strength physics and chemistry adsorption film, make it to be unlikely destruction under high pressure, high temperature and fierce rubbing effect.Can prevent or reduce the direct contact between workpiece, chip, cutter three, reach the object reducing friction and bonding, play fabulous lubrication.
Triethanolamine oleate is a kind of cats product, is added in cutting fluid as oiliness improver, easily between cutlery and cutting workpiece, forms physics adsorption film, thus plays lubrication.In addition, triethanolamine oleate and extreme pressure anti-wear additives also have good collaborative wear-resistant effect, and lubricity also can be made to significantly improve.
The quality of cutting fluid cleaning performance, is closely related with the perviousness of cutting fluid and mobility, surface tension is low, the cutting fluid of perviousness and good fluidity, and cleaning performance is all right.And nonionogenic tenside lipid acid sorb owing to there being content not low in cutting fluid is smooth and the existence of cats product, the two coordinative role, significantly reduces the surface tension of cutting fluid, enhances perviousness and the mobility of cutting fluid significantly.Thus there is good cleaning performance.
The cooling effect of cutting fluid, depends on its thermal conductivity, specific heat, vaporization heat and vaporization rate etc.The thermal conductivity of water is 3 ~ 5 times of oil, and specific heat is 2 ~ 2.5 times of oil, and the cooling performance of Gu Shui is much more superior than oil.Containing more moisture in novel water-based cutting fluid, so cooling performance is given prominence to.
Rust-preventive agent kind is many, but in semi-synthetic cutting fluid, rust-preventive agent has special requirement, not only wants to play rust inhibition, and the HLB value compromise of this rust-preventive agent of interpolation, can be dissolved in oil, and have certain emulsifying effect in water.In a large amount of processs of the test, find to use single rust-inhibiting additive, large not as good as the effect using several rust-preventive agent to join together simultaneously, but be not at will several rust-preventive agent is mixed the effect just playing enhancing, a lot of rust-preventive agent mixes and can not play synergy, even not as good as the effect of single rust-preventive agent.And the present invention is through a large amount of tests, there is certain collaborative amplification between this rust-preventive agent combination provided, greatly strengthen its effect.
Nonionogenic tenside lipid acid sorb is smooth simultaneously itself has antirust and preservative activity; composite synergistic effect is produced with the sanitas added; absorption protective film is formed in metallic surface; passivation film; thus blocked cathode and anode corrosion process; owing to there being fine and close shoe epiphragma, effectively can resisting the immersion of water molecules, oxygen and other corrosivess in medium, there is excellent anticorrosion, rustless property.
beneficial effect of the present invention:complete synthesis magnesium alloy cutting fluid of the present invention, the harmful compositions such as not chloride, triazine, aromatic hydrocarbon, Sodium Nitrite, to no skin irritation, friendly to operator; Outstanding anti-bubble, can be used for high-pressure system and require the operational condition of high air release property, soft or hard water is suitable for; Have good heavy bits, provide cutting swarf and cut the rapid subsidence segmented, maintain system clean and easily clean out contaminants, oil slick is very fast to be separated completely on the liquid level of cutting fluid; Good cooling and cleaning, keep the clean of lathe and workpiece, reduces goo and remain; Lubricity is superior, can form oil-bound film in cutting zone, and cutting fluid last non seizure load PB value reaches more than 765N, and most high energy reaches 820N, far above 500N in prior art.The germ resistance of cutting fluid is extremely strong, and life cycle is more than 12 months, is more than 2-4 times of magnesium alloy cutting fluid life cycle on the market; The cutting fluid free from extraneous odour of rational Design on Plane of environment-friendly type formula, to skin toxicological harmless, non-stimulated, can the health and safety of effective guarantee operator.
