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, in time take away the heat of generation in the cutting zone to reduce cutting temperature, reduce tool wear, improve tool life, thereby enhance productivity, improve workpiece surface roughness, guarantee Workpiece Machining Accuracy, reach economic optimum.Therefore, using cutting fluid is the important measures that improve processing quality and 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 functions: 1. erosion resistance.2. anti-putridness.3. water quality adaptability.4. paint adaptability.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 been subject to the restriction of environmental regulation increasingly stringent.Traditional aspects such as oil base cutting fluid rust-preventing characteristic, stability, cooling and environmental protection obviously lag behind the development of modern Machining Technology for Cutting, and beginning is to the water-base cutting fluid development of nuisanceless or low public hazards.
In developed country, microemulsion generally uses, and is studying energetically Environmental Protection Cutting Fluid.Domestic also, life-span long synthetic cutting fluid, microemulsion transition good from emulsion to performance.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 side effect is little, processing characteristics is superior cutting fluid.The emphasis of research and development is at present: vegetables oil and synthetic ester that mineral oil is biodegradable gradually replace; 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 by the following method:
Synthesizing of A additive: get the mixing in 1: 1 in molar ratio of fatty acid ester and hydrazine hydrate 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 ethyl acetate back flow reaction 0.5～3 hour in 1: 1 in molar ratio; Add again trolamine 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%, disodium ethylene diamine tetraacetate 0.1～1.0%, trolamine 1～10%, additive 1～10%, distilled water surplus; Regulate pH value to 7.5～9 with alkaline matter and make Environmental Protection Cutting Fluid.
The additive that the present invention synthesizes is faint yellow solid to reddish-brown or viscous liquid, and is water-soluble.It is a kind of tensio-active agent, has simultaneously wear-resistant and characteristics high lubricity.
In the building-up process of additive, fatty acid ester is fatty acid methyl ester, ethyl ester, positive butyl ester or other the fatty acid 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 water better in the cutting fluid, strengthens simultaneously the lubricity of cutting fluid.
Described disodium ethylene diamine tetraacetate can form with metal ion the water soluble complex of stabilizer pole.
Described trolamine is a kind of water miscible rust-preventive agent, can effectively protect the metallic surface, anti-oxidation.
Cutting fluid of the present invention does not contain the noxious chemicals such as nitrite that human body or environment are had a negative impact, organic phenol, has the characteristics of antirust, wear-resistant and high lubricity.
