Abstract

The invention relates to a high-speed electrospark wire-electrode cutting fully-synthetic liquid composition. The high-speed electrospark wire-electrode cutting fully-synthetic liquid composition comprises 8 to 20% of composite oleic acid soap, 3 to 15% of a polybasic acid amide, 3 to 10% of a composite borate, 5 to 15% of a pH regulator, 0.3 to 1% of a copper corrosion inhibitor, 1 to 2% of a polyether, 0.05 to 0.15% of a defoamer and the balance purified water. The high-speed electrospark wire-electrode cutting fully-synthetic liquid composition for molybdenum wires or brass wires is characterized in that the water-soluble soap and the polybasic acid amide form a fully-synthetic liquid; and the fully-synthetic liquid, the composite borate and the polyether are compounded into the high-speed electrospark wire-electrode cutting fully-synthetic liquid composition having the good effect of preventing a high-speed wire-feeding cutter from rusting. A carbon steel workpiece treated by the high-speed electrospark wire-electrode cutting fully-synthetic liquid composition has a bright surface. The high-speed electrospark wire-electrode cutting fully-synthetic liquid composition has high cooling properties and strong washing capacity, replaces an emulsion and a semi-synthetic microemulsion used in the early time, reduces operating environment pollution caused by processing oil, and has excellent deionization thereby effectively maintaining conductivity in operation and reducing a processing cost.

Description

The complete synthesis fluid composition of a kind of high-speed electric spark Linear cut

Technical field

The present invention relates to a kind of Metalworking fluid compositions for high-speed electric spark Linear cut; it has higher rust-preventing characteristic and cooling scourability; stable electrical conductance condition can be met; processed surface smoothness and working accuracy is made to reach criterion of acceptability; the requirement of the protection environment of plant, reduces liquid waste disposal.

Technical background

The Soviet Union in nineteen sixty invented by early stage Linear cut electromachining machine, the wire cutting liquid of utilization or mineral oil, its good insulating, and pole distance is little, and process velocity is lower than now, and therefore practicality is restricted.Along with the development in epoch, line cutting technology perfect, presents multipleization working fluid to adapt to different process.Wire cutting liquid, also known as Linear cut cooling fluid, is a kind ofly have good cooling, lubrication, cleaning and antirust function, and has certain dielectric strength, goes to dissociate, arc extinguishing, prevents the liquid of fracture of wire and the performance such as long service life, safety non-toxic.

Line tangent line cuts the oiliness cutting liquid that the domestic and international first kind product of liquid is mainly major ingredient with mineral oil, is made up of mineral oil and oil-soluble substance completely, directly adds and can not be watered during use, such as: extreme pressure cutting oil, electrical spark liquid.This series products environmental pollution is comparatively large, inflammable, and cleaning workpiece needs the alkane solvent of nonpolar chlorine simultaneously, and to human body toxic side effect, this type of cutting liquid is substantially superseded.

Domestic at present to cry widely used be Equations of The Second Kind product water-based cutting liquid or water-latex type cutting liquid, and this series products can be water-soluble or formed emulsion by water-dispersion.Oil-in-water type is formed primarily of mineral oil, emulsifying agent, necessary additive, and this class is polluted large, and cooling performance is poor; Narrow and to be shapingly made up of emulsifying agent, mineral oil, water soluble anti-rust agent etc., pollute large, rustless property is poor; Synthesis type is then be made up of water-soluble substances completely, and dielectric properties are bad stable;

High-speed electric spark Linear cut complete synthesis liquid polycarboxylic acid acid amides involved by this project and the composite use of Composite borate make product have splendid rust-preventing characteristic, compound oleate soap makes dielectric properties stablize, Middle molecule acid has high cleaning, high scourability, cutting efficiency is higher, its stable dielectric properties are that other several classes can not be compared, harmless, and greatly reduce the treatment cost of waste liquor of producer.

Summary of the invention

Main purpose of the present invention is to provide the complete synthesis liquid of a kind of high-speed electric spark Linear cut, has the performance of excellent stable electrical conductance, can meet the requirement of client's luminance brightness and dimensional precision under lower concentration.Complete synthesis liquid provided by the invention possesses splendid dielectric properties, scourability, cooling performance, and meanwhile, the wire cutting liquid that this invention makes does not have irritating smell, harmless, is easy to removing after processing yet, ensure that the clean of operating environment.

Another object of the present invention is to provide the complete synthesis liquid of a kind of high-speed electric spark Linear cut and has outstanding rust-preventing characteristic and cleaning, carrying out smoothly of processing can be ensured, ensure the floor cleaning of factory, because be without oily complete synthesis liquid, also eliminate a lot of troubles to the later stage liquid waste disposal operation of workman, save human cost and working fluid cost.
