Abstract
The invention discloses high-performance environment-friendly magnetic material cutting fluid, which consists of an antirusting agent, surfactants, a lubricating agent, a preservative, a copper corrosion inhibitor and water. In the invention, a special water soluble polymer serving as a lubricating agent is combined with various surfactants, the antirusting agent and the copper corrosion inhibitor, so the cutting liquid has high lubricating performance and antirusting performance, the yield of processed magnetic materials is high and the processing precision is high. Because the use of strong alkali such as sodium hydroxide and potassium hydroxide is avoided, the dissolution of adhesive can be prevented. Meanwhile, the cutting liquid does not contain nitrites and therefore is an environment-friendly magnetic material cutting liquid.
Description
Technical field
The present invention relates to the cutting fluid used in a kind of magneticsubstance course of processing.
Background technology:
To the machining manufacturing of magneticsubstance (alloys such as samarium, cobalt, neodymium), tradition is used mostly is the oiliness cutting fluid.Although oiliness cutting fluid lubricity is good, in use there are many drawbacks such as mist of oil, inflammable, contaminate environment.Therefore present many enterprises have used water-soluble metalworking liquid instead magneticsubstance have been carried out machining manufacturing.
Be machining quality (i.e. smooth finish and the planeness of section), the prolongation cutting-tool's used life (reducing production costs) of guaranteeing magneticsubstance, this just requires the lubricity of used water-soluble metalworking liquid will get well (being that frictional coefficient is little), rustless property will be got well (can not produce corrosion to workpiece and machining tool in the course of processing).
Be convenient processing, during the magneticsubstance machining, usually all be to be that binding agent is fixed on the anchor clamps with the magneticsubstance workpiece with wax, then carry out machining by outer round-bladed knife sheet, interior round-bladed knife sheet and wire cutting machine, this just requires used water-soluble metalworking liquid on the impact of binding agent little (do not make its very fast dissolving, cause workpiece to come off).
But the performance quality of the at present commercially available water-soluble metalworking liquid that is used for the magneticsubstance machining is unsatisfactory, main drawback: the one, lubricity relatively poor (frictional coefficient is large), workpiece planeness and smooth finish after causing processing are difficult to reach processing requirement, cutter life is short, affects production cost; The 2nd, the rust-preventive agent that adds in the cutting fluid affects the adhesive property (binding agent is soluble after soaking, and causes workpiece easily to come off) of binding agent; The 3rd, contain the objectionable impuritiess such as Sodium Nitrite in the prescription, jeopardize environmental safety and HUMAN HEALTH.
Summary of the invention
The high-performance environment-friendly type magnetic material cutting fluid that the object of the present invention is to provide a kind of high lubricity, anti-workpiece to come off.
Technical solution of the present invention is:
A kind of high-performance environment-friendly type magnetic material cutting fluid, it is characterized in that: the one-tenth by following weight percent is grouped into:
Rust-preventive agent is one or more and Monoethanolamine MEA BASF, diethanolamine, the trolamine in the organic acid, p-tert-butyl benzoic acid, p-nitrobenzoic acid of boric acid, carbon number 8~18, the mixture of one or more formation in the α-amino isopropyl alcohol, and the pH value of mixture is 8~9.
Tensio-active agent is the mixture of one or more formation in the organic acid of carbon number 8~18 and Monoethanolamine MEA BASF, diethanolamine, trolamine, the α-amino isopropyl alcohol, and the pH value of mixture is 8~9; Or tensio-active agent is aliphatic alcohol polyethenoxy (5~12) ether or alkylphenol-polyethenoxy (5~12) ether.
Lubricant is polyoxyethylene polyoxypropylene block ether; Sanitas is one or more in 1,2 benzothiazole-3-ketone, 1,2 benzisothiazole, the s-triazine; Copper inhibitor is benzotriazole, tolyltriazole, 1H-1, one or more in 2,4-triazole, the alpha-mercapto benzothiazole.
The present invention adopts special water-soluble polymers as lubricant, composite kinds of surface promoting agent, rust-preventive agent and copper inhibitor, so that this product has excellent oilness and rust-preventing characteristic, processing magnetic material yield rate and working accuracy are high.Because the present invention does not use the highly basic such as sodium hydroxide, potassium hydroxide, therefore can prevent the dissolving of binding agent.Product does not contain nitrite simultaneously, and environmental protection is a kind of eco-friendly magnetic material cutting fluid.
1, this product has good lubricity.This Project Product 5% diluent frictional coefficient is compared with commercially available product less than 0.201, reduces on year-on-year basis 20%; Use this Project Product machining, compared with use commercially available prod greater than 7 days cutter life, improves on year-on-year basis 40%.
Sample | This product | Commercially available product |
Coefficientoffrictionμ | 0.201 | 0.261 |
Cutter life | 7 days | 5 days |
2, this product can guarantee that wax is that binding agent soaks 3 hours non-whitenings, do not dissolve in this product 5% diluent, and workpiece does not come off.
3, this product safety health, reliable in quality.Prescription does not use the objectionable impuritiess such as Sodium Nitrite, the biological Lethal Dose 50 LD50>5000mg/kg of product, biological toxic limit medium dose LC50>5000mg/m
3, apnea road mucous membrane irritation, friendly to human and environment.
The invention will be further described below in conjunction with embodiment.
