Description
Technical field
The present invention relates to a kind of fully synthetic cutting fluid composition, more particularly to a kind of hard water resistance stability and rustless property it is excellent
Different fully synthetic cutting fluid composition.
Background technology
Cutting fluid plays a part of lubricating in metal cutting process and cools down machining tool and part, and its performance refers to
Mark directly affects the quality, efficiency and cost of machining.Aqueous cutting fluid comes out the 1940s, to being at present
Only, application of the water base fluid in cutting field has tremendous development.With the development of technology, there is fully synthetic cutting in the market
Liquid, it is made up of surfactant, water soluble anti-rust agent and soluble oil, is a kind of minimum colloidal solution of particle, its
Wetability is good, and penetrating power is strong, and cooling and cleaning performance are good, also have certain lubrication, and its stability is compared with emulsion
It is good, service life length.At the scene in use, fully synthetic cutting fluid usually requires to be diluted with more than 90% water.If dilution
Liquid is larger with water water hardness, easily causes dilution observability to be deteriorated, and can occur when serious with the functional additive of system anti-
Should, it separated out, condensed and precipitate.Especially in the larger area of water hardness, it is desirable to which the cutting fluid of application has good resist
Hard water ability, effectively avoid the generation of oil soap.
There are numerous report and patent document on water-base cutting fluid composition both at home and abroad.Patent CN101104831A is reported
A kind of microemulsified stainless steel coolant.The cutting fluid is by APES or AEO nonionic table
The additives such as face activating agent, chlorinated paraffin, oleic acid, triethanolamine and base oil, water composition, the cutting fluid for being exclusively used in stainless steel add
Work.Patent CN101560430A reports a kind of fully synthetic cutting fluid, using surfactant, polyethylene glycol, borax, sterilization
Agent, pH value regulator and balance deionized water reconcile and formed, and solve the problems, such as that existing fully synthetic cutting fluid cobalt element leaches.Specially
Sharp JP2007186537 discloses a kind of processing cast iron and non-discolouring high-performance water base cutting fluid, by saturated fatty acid, insatiable hunger
Formed with aliphatic acid, dicarboxylic acids, fatty acid metal salts etc..Patent CN102876439A discloses a kind of cutting fluid, by diethyl
Hydramine, MEA, succinic acid, borate, glycerine, emulsifying agent, antirust agent etc. form.Above-mentioned patent document do not mention with
Important component of the isocyanate-modified dispersant as cutting fluid, prepare hard water resistance stability water-base cutting fluid.
Patent US3215707, patent CN1186078A disclose a kind of succinic acid and polyhydroxy-alcohol substituted with polyolefin
The method that reaction prepares ester type ashless dispersant, its synthesis technique is using alkaline metal salt as catalyst；Patent CN1258728A is public
A kind of preparation method of Ashless dispersant for boron-containing post-crosslinked butanediimide is opened, i.e., by the way that the succimide of post-crosslinking is divided
The boronating agent of powder and particle diameter less than 150 microns is in the presence of fatty alcohol accelerator of the boiling point higher than 100 DEG C, less than promotion
Reaction obtains at a temperature of agent boiling point.Patent CN101173201A discloses a kind of preparation method of boron phosphatization ashless dispersant,
Ashless dispersant, phosphor-included additive, boric acid, ethoxylated fatty amine, water and fatty alcohol are mixed, at 70~100 DEG C
Reacted, separate and collect product.Patent CN1245211A discloses antioxidative succinimide lubricating oil dispersant and its system
It is standby, this method by by low-carbon ester and polyisobutene succinimide containing shielding phenol acid or base catalyst presence
Under, react and be made at 80~200 DEG C, the dispersant has preferable antioxygen property and detergent-dispersant performance energy.
Water-base cutting fluid is in an increasingly wide range of applications in current mechanical processing industry.Cutting fluid is used as a kind of
Special mechanical processing process medium, due to the influence of itself compositing characteristic and extraneous factor, it may go out in use
The problem of now some are common, wherein hard water resistance or soap rendezvous problem also increasingly turns into highly important phenomenon.Water-base cutting fluid is certainly
Right possesses the condition for forming soap, has substantial amounts of calcium ions and magnesium ions in one side water, is on the other hand most in cutting formula of liquid
Aliphatic acid can be added, the two is readily formed fatty acid soaps.The formation of fatty acid soaps can't have bad to the performance of cutting fluid
Influence, the aggregation of soap is only the key issue for needing solve.Under hard water situation especially long-time moisturizing because liked calcium and magnesium from
Son is accumulative, can form substantial amounts of soap, and fatty acid soaps generation aggregation be able to can then produce certain to cutting fluid and mechanical processing process
Negative effect, it is possible to cause emulsion is unstable, cause concentrate consumption increase.When soap is in lathe or central fluid supply system
Be bonded together in system with compositions such as foam, metal dust, miscellaneous oil, formed scum silica frost even thick substances when, the problem of bringing
Can be more, they are floated or are deposited in working solution, and not only filtration system is impacted, causes blocking, the consumption of filter paper
Increase, on-site sanitation situation it is poor, and remain in and can cause machining accuracy problem in cutter, measurer and transmission system.These are asked
Topic all proposes higher requirement to the hard water resistance stability of cutting fluid itself.
