Problems solved by technology

[0004] There is no processing fluid specifically for zinc and its alloys on the market. After processing zinc alloys with water-soluble cutting fluids, white spot corrosion is extremely prone to occur. Depending on the influence of various parameters of the processing fluid, the workpiece will White spot-like corrosion will appear within 24 hours, and odor will generally appear in 1 to 3 months in the service life
And generally for the mixed processing of ferrous metals and zinc alloys can not take into account

Abstract

The invention belongs to the technical field of zinc alloy processing, and provides working fluid used for zinc alloy, aiming at solving the technical problem of easy corrosion in the use process of zinc alloy in the prior art. The working fluid comprises the following components by weight percent: 10%-25% of base oil, 3%-10% of fatty acid, 5%-15% of mixed alcohol amine, 4%-8% of boric acid, 1%-5%of non-ferrous metal corrosion inhibitor, 3%-5% of a sulfonate antirust agent, 1%-5% of binary acid, 1%-3% of polyether amine, 3%-8% of an ester lubricant, 0.3%-1.0% of an ester coupling agent, 2%-7%of a nonionic surfactant, 0.5%-2.0% of a hard water resistant stabilizer, 2%-5% of a sterilizing agent, 0.05%-0.15% of a defoaming agent and the balance of deionized water. The working fluid has thecharacteristics of preventing corrosion of zinc alloy, and prolonging the service life of zinc alloy.

Description

technical field [0001] The invention belongs to the technical field of zinc alloy processing, and in particular relates to a processing fluid for zinc alloy. Background technique [0002] Zinc alloy is an alloy composed of zinc and other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and other low-temperature zinc alloys. Zinc alloy has a low melting point, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, and the residual waste is easy to recycle and remelt; but the creep strength is low, and it is prone to dimensional changes caused by natural aging. [0003] Zinc alloys, also known as zinc-based alloys, are generally divided into binary alloys, ternary alloys and multi-element alloys. Binary zinc-based alloys generally refer to zinc-aluminum alloys; ternary zinc-based alloys generally refer to zinc-aluminum-copper alloys; multi-element alloys generally refer to zinc-alum...
