Abstract

The invention discloses metal drawing oil which is characterized by containing the following components in percentage by weight: 10-30% of oiliness agent, 20-40% of extreme pressure additive, 0-0.5% of antioxidant, 0-5% of corrosion inhibitor and the balance of base oil. The product disclosed by the invention contains a great deal of oiliness agent and extreme pressure additive, and can be used for providing favorable lubricating property and strong adhesive force, reducing the heat in a forming process, effectively lubricating a workpiece and a die, favorably protecting the die and prolonging the service life of the die. Due to the excellent extreme pressure property, the workpiece quality is effectively improved and the processing power is effectively increased under high, deep and difficult processing conditions; and the metal drawing oil is high in viscosity index, good in viscosity-temperature characteristics and high in temperature and weather adaptability.

Description

Metal stretching oil

Technical field

The present invention relates to a kind of metal stretching oil.

Background technology

In recent years, along with the reach of science, the metal products that relates to the different shapes style in the daily life is more and more, and is handsome in appearance because of it, durablely accepted by every field.Along with the complexity of metal products moulding and improving constantly of quality, its punching stretch technique also has simple to complicated, and difficulty increases, and is also harsher to the specification of quality of drawing oil.Drawing oil difference in quality in the market is very large, and there is the quality control index of oneself in every company.Also exist in actual applications and pull, perforation, the problem such as stretch inhomogeneous, product percent of pass is low.And the viscosity of this series products is larger, and strong adhesion increases difficulty for the wash procedure in rear road.

Summary of the invention

The objective of the invention is in order to overcome deficiency of the prior art, provide a kind of oilness good metal stretching oil.

For realizing above purpose, the present invention is achieved through the following technical solutions:

Metal stretching oil is characterized in that, comprises according to weight percent: oiliness improver 10%-30%; Extreme-pressure additive 20%-40%; Oxidation inhibitor 0%-0.5%; Corrosion inhibitor 0%-5%; The base oil surplus.

Preferably, also comprise nonionogenic tenside 0%-8% according to weight percent.

Preferably, described base oil is selected from low-sulfur paraffinic crude base oil.

Preferably, described oiliness improver is selected from one or more in vegetables oil, animal oil, synthetic ester or the middle low molecular weight polycaprolactone butylene.

Available vegetables oil includes but not limited to rape oil, salad oil and soya-bean oil.

Available animal oil includes but not limited to prepared lard.

Available synthetic ester includes but not limited to tricarboxymethyl propane oleate, TriMethylolPropane(TMP) cocounut oil acid esters, oxidation rape oil, high molecular polymerization ester, such as GY series, pentaerythritol monooleate and the butyl oleate of Lu Borun.

Available middle low molecular weight polycaprolactone butylene includes but not limited to PB950, PB1300, PB1400 and PB2400.

Preferably, described extreme-pressure additive is that in chloride, sulphur or the phosphorus extreme pressure agent one or more are composite.

Available chloride extreme-pressure additive is selected from one or both in clorafin, the chlorination fat.

Available sulfur-bearing extreme-pressure additive includes but not limited to one or more in sulfide aliphatic acid ester, olefine sulfide, sulfuration triglyceride, sulfuration lard, dialkyl group pentasulfide, the dialkyl disulfides thiosulfate.

Available phosphorous extreme-pressure additive includes but not limited to neutral phosphate, phosphorous acid ester, thiophosphatephosphorothioate and phosphorus-nitrogen compound.

Preferably, corrosion inhibitor is selected from one or both in epoxy soybean oil and the calcium mahogany sulfonate.

Preferably, described ionic surfactant pack is drawn together one or more in fatty alcohol-polyoxyethylene ether, sapn, the tween.

Preferably, described oxidation inhibitor comprises one or both in phenolic antioxidant and the amine antioxidants.

Available phenolic antioxidant includes but not limited to: 2,6 ditertiary butyl p cresol; 2,4,6 ,-tri-butyl-phenol; Antioxidant 2246; Antioxidant 300.

Available amine antioxidants includes but not limited to: the N-phenyl-a-naphthylamine; N, the N/-diphenyl-para-phenylene diamine.

Product contains a large amount of oiliness improvers and extreme pressure agent among the present invention, and good oilness and strong adhesion can be provided, and can reduce the heat in the moulding process, can effectively lubricate workpiece with mould, and is good to the mould protection, can prolong the life-span of mould.Excellent extreme pressure property guarantees under high, dark, difficult processing operating mode the quality of Effective Raise workpiece and working power; Viscosity index is high, and viscosity temperature characteristic is good, and is high to the adaptability of thermal climate.Added a certain amount of tensio-active agent and easily cleaning; Good antirust property can prevent workpiece corrosion.Range of viscosities is wide, can be according to the oil product of different operating mode allotment different viscosity.Can pass through the good composite of different additive, applicable unlike material comprises carbon steel, stainless steel, high temperature steel, the processing of aluminium alloy and copper alloy.
