Abstract

The present invention relates to a kind of aluminum alloy cutting fluid and preparation method thereof, it is characterised in that includes the raw material of following percentage by weight：Naphthene base crude oil 15 30%, borate containing sulfur and nitrogen 5 8%, potassium borate 3 5%, triethanolamine oleate 2 4%, nonionic surfactant 4 8%, anion surfactant 2 4%, corrosion inhibiter 1 3%, antirust agent 1 3%, stabilizer 0.5 2%, defoamer 0.1 1.0%, compound disinfectant 0.1 0.5%, surplus are deionized water.The aluminum alloy cutting fluid of the present invention has good extreme pressure anti-wear, corrosion-inhibiting, defoaming and stability, and to cutter not damaged, to workpiece without fretting wear, it is easily separated to cut pin, long lifespan, has no irritating odor, low toxicity, environmental protection, easy cleaning degraded；Also there is excellent cleaning and cooling performance, can quickly take away aluminium alloy in amount of heat caused by high-speed cutting processing and cutting powder.

Description

Aluminum alloy cutting fluid and preparation method thereof
Technical field
The invention belongs to metalworking fluid technical field, more particularly to a kind of aluminum alloy cutting fluid and preparation method thereof.
Background technology
In the prior art, aluminium alloy density is low, but intensity is higher, and plasticity is good, can be processed into various section bars, has excellent Thermal conductivity and preferable corrosion resistance, purposes industrially is very extensive, and usage amount is only second to steel.But aluminium alloy Chemism is relatively strong, quality is very soft, and viscosity is strong, easily occurs the problems such as viscous knife, discoloration in processing, therefore process for aluminium alloy The demand of special cutting fluid is also growing.Aluminum alloy cutting fluid in the market is in use, it may appear that dilute Releasing liquid has phenomena such as oil soap, emulsifying rate is slack-off, and the oil droplet not emulsified completely can adsorb and cause blackspot in workpiece surface, cause work Part is scrapped, and influences finished workpart rate, causes aluminium to waste serious, while causing fluid to waste, does not reach preferable use Effect.
Further, since it can be utilized by the microorganism containing mineral oil, fatty acid soaps, amine, sulfonate and water etc. in cutting fluid Composition, thus be subject to the decomposition of microorganism (such as bacterium and fungi), while cause the performances such as the antirust of cutting fluid, lubrication to drop It is low, ultimately result in cutting fluid corruption and foul.To prevent that water-base cutting fluid is putrid and deteriorated, generally require cutting formula of liquid composition or Suitable bactericide is added in its dilution, to control the growth and breeding of microorganism.But long-term use of homologous bactericidal agent, micro- life Thing can develop immunity to drugs, and current bactericide has very big toxicity, can absorb, lead from the skin of human body after Long Term Contact Slow poisoning is caused, seriously endangers health.
The content of the invention
It is an object of the invention to provide a kind of aluminum alloy cutting fluid and preparation method thereof, the aluminum alloy cutting fluid has good Extreme pressure anti-wear, corrosion-inhibiting, defoaming and stability, have no irritating odor, low toxicity, environmental protection, easy cleaning degraded.
What the present invention was realized in：
A kind of aluminum alloy cutting fluid, it is characterised in that include the raw material of following percentage by weight：Naphthene base crude oil 15-30%, Borate containing sulfur and nitrogen 5-8%, potassium borate 3-5%, triethanolamine oleate 2-4%, nonionic surfactant 4-8%, anion Surfactant 2-4%, corrosion inhibiter 1-3%, antirust agent 1-3%, stabilizer 0.5-2%, defoamer 0.1-1.0%, compound kill Microbial inoculum 0.1-0.5%, surplus are deionized water.
