Description
Technical field
The present invention relates to a kind of environmental type cutting fluid.
Background technology
Metal cutting processing is the most common, most widely used a kind of in the metal processing.Cutting fluid is the important supplementary material of metal cutting processing.The purpose of using metal working fluid is exactly the friction that reduces between cutting force and cutter and the workpiece; The heat of in time taking away generation in the cutting zone reduces tool wear to reduce cutting temperature, improves tool life; Thereby enhance productivity; Improve workpiece surface roughness, guarantee the workpiece working accuracy, reach economic optimum.Therefore, using cutting fluid is to improve processing quality and the important measures that cut down finished cost.
Cutting fluid has cooling, lubricated, cleaning and antirust four kinds of major functions.In recent years, because the improving constantly of cutting technology, the continuing to bring out of advanced cutting machine, the development of cutter and workpiece material has promoted the update of cutting fluid kind, also requires cutting fluid to have following function: 1. erosion resistance.2. anti-putridness.3. water quality flexibility.4. paint flexibility.5. stable.6. security and the hypotoxicity 8. defoaming that 7. has no irritating odor.9. emission treatment is easy.10. liquid waste disposal is easy.Especially environment in recent years protection and human health become the focus of whole society's concern day by day, and cutting fluid can pollute and damage environment and human body, so the use of cutting fluid and liquid waste disposal have received the restriction of environmental regulation increasingly stringent.Traditional aspects such as oil base cutting fluid rust-preventing characteristic, stability, cooling property and environmental protection obviously lag behind the development of modern Machining Technology for Cutting, begin the water-base cutting fluid development to nuisanceless or low public hazards.
In developed country, microemulsion generally uses, and is studying Environmental Protection Cutting Fluid energetically.Domestic also good to performance, that the life-span is long synthetic cutting fluid, microemulsion transition from emulsion.At present, the key content of cutting fluid research both at home and abroad comprises: the development of high-performance cutting fluid, the feed liquid method that prolongs cutting fluid work-ing life and the research of minimizing discharging of waste liquid amount, more effective and more economical method for treating waste liquid research etc.And be the important directions of cutting fluid research to ecotope and the human health spinoff is little, processing characteristics is superior cutting fluid.The emphasis of research and development is at present: MO is replaced by biological degradation good vegetables oil and synthetic ester gradually; The oil base cutting fluid is replaced by water-base cutting fluid gradually; Exploitation excellent property and harmless and additive environmentally safe.
Summary of the invention
The object of the present invention is to provide a kind of Environmental Protection Cutting Fluid.
A kind of Environmental Protection Cutting Fluid is characterized in that this cutting fluid prepares through following method:
Synthesizing of A additive: get the mixing in 1: 1 in molar ratio of fatty ester and Hydrazine Hydrate 80 and be dissolved in the ethanol, back flow reaction 12～48 hours is cooled to below 20 ℃, and suction filtration with absolute ethanol washing, suction filtration, gets white solid; White solid and anhydride compound were dissolved in chloroform or the ETHYLE ACETATE back flow reaction 0.5～3 hour in 1: 1 in molar ratio; Add trolamine again in 1: 1 in molar ratio～1: 3, continued back flow reaction 0.5～2 hour, boil off solvent, obtain additive;
The preparation of B cutting fluid: the weight percentage of each component of cutting fluid is polyoxyethylene glycol 5～15%, silicone emulsion 0.25～1.0%, EDTA Disodium 0.1～1.0%, trolamine 1～10%, additive 1～10%, distilled water surplus; Regulate pH value to 7.5～9 with alkaline matter and process Environmental Protection Cutting Fluid.
Synthetic additive of the present invention is faint yellow solid or viscous liquid to reddish-brown, and is water-soluble.It is a kind of tensio-active agent, has wear-resistant simultaneously and characteristics high lubricity.
In the building-up process of additive, fatty ester is fatty acid methyl ester, ethyl ester, positive butyl ester or other the fatty ester that contains 6～18 carbon atoms that contains 6～18 carbon atoms.
In the building-up process of additive, anhydride compound is Succinic anhydried or MALEIC ANHYDRIDE or Citric anhydride.
Described molecular weight polyethylene glycol is 400～2000, and polyoxyethylene glycol can make that each component is dispersed in the water better in the cutting fluid, strengthens the lubricity of cutting fluid simultaneously.
Described EDTA Disodium can form the water soluble complex of stabilizer pole with metals ion.
Described trolamine is a kind of water miscible rust-preventive agent, and effectively the protective money metal surface is prevented oxidation.
Cutting fluid of the present invention does not contain noxious chemicals such as the nitrite that human body or environment are had a negative impact, organic phenol, has the characteristics of antirust, wear-resistant and high lubricity.
