Description

One vegetable oil base titanium alloy emulsifying working fluid
Technical field
The invention belongs to intermetallic composite coating auxiliary agent technical field, specifically, is a kind of plant suitable for aero titanium alloy Oil base emulsifying working fluid.
Background technology
Titanium alloy has the advantages that specific strength is high, heat resistance is good, corrosion-resistant, aboundresources, has extensively in Aeronautics and Astronautics field General application, and the industrial departments such as shipbuilding, metallurgy, chemical industry, light industry, medical treatment are gradually expanded to, have the potentiality that grow a lot；However, Titanic alloy machining is poor, belongs to difficult-to-machine material, is embodied in：Poor thermal conductivity, plasticity are low, hardness is high, elastic modelling quantity is low, bullet Property deflection is big, chill phenomenon is serious.Its relative machinability is 25%-the 38% of No. 45 steel.
To improve the working (machining) efficiency and precision of titanium alloy, generally individually it is processed under conditions of using working fluid.Commonly Working fluid is poor to titanium alloy greasy property, working (machining) efficiency is low；Additionally, traditional processing liquid oil, biodegradation based on mineral oil Property is poor, and extended residual causes environmental pollution in water body and soil, meanwhile, the oil smoke produced during use can be to operator Body produces harm；Sodium nitrite antirust agent, phenol series bactericidal agent and the aldehydes being added thereto to improve working fluid performance Compound etc. is toxic, and Long Term Contact can increase cancer morbidity；Contained S in mineral oil, surfactant and extreme pressure agent, P, Cl etc. can make xerosis cutiss, cracking, redness, cause dermatosiss.
Therefore, the environment-friendly titanium alloy emulsifying working fluid tool for researching and developing high-lubricity is of great significance.
The content of the invention
The invention is solution the problems of the prior art, there is provided a kind of greasy property is good, stability is high, rust-preventing characteristic Can protrusion, hard water strong adaptability, the plant oil base titanium alloy emulsifying working fluid friendly to operator and ecological environment security.
The titanium alloy emulsifying working fluid that the invention is provided, by weight, including：
Base oil 20-60 parts,
Emulsifying agent 3-30 parts,
Base number lays in agent 5-30 parts,
Other auxiliary agents 0-40 parts,
Water.
Wherein, described other auxiliary agents preferably include following one or more component：
Corrosion inhibitor 3-20 parts,
Antibacterial 0.5-5 parts,
Antioxidant 0.2-5 parts,
Defoamer 0.2-5 parts.
Wherein, the addition of water is so that the titanium alloy emulsifying working fluid is able to maintain that stable emulsion state and reaches tool There is good mobile performance to be defined, those skilled in the art can be adjusted as needed and add, the addition of water in this case Typically in 3-15 weight portions.
Wherein, the base oil is oxidation vegetable oil, and preferred epoxide number is 3% -6% oxidation Oleum Brassicae campestriss.Invention Crinis Carbonisatus Existing, when epoxide number is 3% -6%, hydroxyl, ester group and the epoxy radicals that oxidation Oleum Brassicae campestriss contain mutually coordinated can be acted on, jail Gu absorption is in titanium alloy surface, continuous lubricating film is formed, workpiece and the friction of cutter, improve and add in sustainable reduction cutwork Work precision；Additionally, unsaturated bond content is low in oxidation vegetable oil, oxidation resistance is strong, is conducive to increasing the service life.
Wherein, the emulsifying agent be aliphatic acid polyethenoxy ether, alkyl Polyethylene Glycol acid esters, the mixture of diterpene carboxylic acid, Preferred mass ratio is (5 ± 0.2)：(2±0.2)：(1±0.2).Inventor's discovery, the poly- second of aliphatic acid polyethenoxy ether, alkyl Diolate oleophylic based structures are similar to oxidation vegetable oil；Diterpene carboxylic acid is a kind of and small molecule resinic acid as fatty acid, The gap of oil-water emulsion interfacial film can be inlaid into, increases interfacial film strength, reduce interface energy；Composite emulsifier HLB value is 5- 7, it is also close with oxidation vegetable oil, therefore there is good emulsification to aoxidizing vegetable oil；Meanwhile, which contains various active base Group, can promote absorption of the base oil to titanium alloy, strengthen film strength, improve lubricity；Additionally, the poly- second of the alkyl of highly branched chain , to hard water strong adaptability, foam is low for diolate.
Wherein, at least one of the base number deposit agent in saturation hydramine, cyclohexylamine, the saturation hydramine are exemplary Example include ethanolamine, diethanolamine, triethanolamine, N methyldiethanol amine, diglycolamine etc..Inventor's discovery, such Base number deposit agent can effectively adjust the pH value and total alkalinity of working fluid, and can increase stability of emulsion to a certain extent.
Further, the base number deposit agent preferably adjusts the pH value of working fluid described in this case to 8-10, now described The preferred addition of base number deposit agent is 10-20 parts.Inventor has found, if cutting fluid PH ＜ 8.0, rustless property is reduced, easily right Metal causes chemical attack, and is more easy to grow putrefaction bacteria；And if PH ＞ 10.0, easy stimulation applications person's skin, meanwhile, perishable two Property metal.
Wherein, the corrosion inhibitor be borate, alcohol ether phosphate, the mixture of methine benzotriazole, preferred matter Amount is than being (7 ± 0.2)：(2±0.2)：(1±0.2).Inventor has found, using the compound corrosion inhibitor not only to single gold Category has good corrosion inhibition, moreover it is possible to effectively slow down the galvanic corrosion between different metal.
Wherein, the antibacterial is Hexahydrotriazine compounds, IPBC, pyridine sulfur copper sodium Mixture, preferred mass ratio are (2 ± 0.2)：(1±0.2)：(1±0.2).Inventor has found that the compounding antibacterial can be effective Suppress antibacterial, the growth of funguses, and it is little to human body and environmental hazard.
Wherein, the antioxidant can be antioxidant conventional in metal working fluid, preferably 2,6- di-t-butyls Paracresol (T501).
Wherein, the defoamer can be defoamer conventional in metal working fluid, preferably polyether-silicone copolymerization Thing.
The beneficial effects of the present invention is：
(1) safety and environmental protection：The present invention does not contain mineral oil, nitrite, phenol and aldehydes additive, without S, P, Cl pole Pressure additive, it is work circumstances safe, tasteless, it is nonirritant to human body skin and respiratory tract；It is degradable, it is environmentally friendly.
(2) high-lubricity：, containing a large amount of oxidation Oleum Brassicae campestriss, composite emulsifier of arranging in pairs or groups can be in titanium alloy surface shape for the present invention Into continuous oil film, with higher Pb values and Pd values, friction of the cutter in surface of test piece can be reduced, improve the processing of workpiece Quality；
(3) excellent antirust rust inhibition：The present invention has good antirust, corrosion inhibition, moreover it is possible to effectively slow down different gold Galvanic corrosion between category.
