Description
Technical field
The present invention relates to a kind of fully synthetic cutting fluid composition, particularly relate to the fully synthetic cutting fluid composition of anti-hard water stability and high rust resistance.
Background technology
Cutting fluid plays lubrication, cooling machining tool and the effect of parts in metal cutting process, and its performance index directly affect the quality of machining, efficiency and cost.Aqueous cutting fluid came out the forties in 20th century, along with the development of technology, market having occurred complete synthesis cutting fluid, be made up of tensio-active agent, water soluble anti-rust agent and soluble oil, is the minimum colloidal solution of a kind of particle, its wettability is good, penetrating power is strong, cooling and cleaning performance good, also have certain lubrication, and its stability comparatively emulsion is good, life cycle is long.When using at the scene, fully synthetic cutting fluid needs the water with more than 90% to dilute usually.If diluent quality of water hardness is comparatively large, easily causes diluent visibility to be deteriorated, can react with the functional additive of system time serious, make it separate out, condense and precipitate.
Numerous reports and patent documentation is had both at home and abroad about water-base cutting fluid composition.Patent CN101104831A reports a kind of microemulsified stainless steel coolant.This cutting fluid is made up of the additives such as alkylphenol polyoxyethylene or fatty alcohol-polyoxyethylene ether nonionogenic tenside, clorafin, oleic acid, trolamine and base oil, water, is exclusively used in the processing of stainless cutting fluid.Patent CN101560430A reports a kind of fully synthetic cutting fluid, adopts tensio-active agent, polyoxyethylene glycol, borax, sterilant, pH value regulator and balance deionized water to be in harmonious proportion and forms, solve the problem that existing fully synthetic cutting fluid cobalt element leaches.Patent JP2007186537 discloses a kind of processing cast iron and non-discoloring high-performance water base cutting fluid, is made up of saturated fatty acid, unsaturated fatty acids, di-carboxylic acid, fatty acid metal salt etc.Patent CN102876439A discloses a kind of cutting fluid, is made up of diethanolamine, monoethanolamine, succinic acid, borate, glycerine, emulsifying agent, rust-preventive agent etc.US5725612 reports a kind of Mannich base and manufacture method thereof, and the alkyl ortho-cresol that this Mannich base is replaced by alkyl and aldehyde, amine react manufacture and obtains, and can suppress the generation of engine deposits.
Water-base cutting fluid is in an increasingly wide range of applications at current mechanical processing industry.Cutting fluid is as a kind of special mechanical processing process medium, and due to the impact of self compositing characteristic and extraneous factor, it in use may occur some common problems, such as anti-hard water or soap rendezvous problem.Having a large amount of calcium ions and magnesium ions in water-base cutting fluid one side water, is mostly can add lipid acid in Method of Emulsified Cutting Fluid on the other hand, and the two is easy to form fatty acid soaps.The formation of fatty acid soaps can't have bad impact to the performance of cutting fluid, and the gathering of soap is only the key issue needing to solve.Under hard water situation, especially long-time moisturizing can form a large amount of soaps, and fatty acid soaps occurs to assemble and then can produce certain negative impact to cutting fluid and mechanical processing process, likely causes emulsion instability, causes concentrated solution consumption to increase.When soap is bonded together with foam, metal-powder, assorted wet goods composition in lathe or in central liquid supply system, when forming scum silica frost or even thick substances, the problem brought can be more, they are floating or be deposited in working fluid, not only filtering system is impacted, cause blocking, the consumption of filter paper increases, on-site sanitation situation is poor, and remain in cutter, measurer and transmission system and can cause working accuracy problem.These problems are all had higher requirement to the anti-hard water stability of emulsion cutting fluid self.
