Abstract
The present invention discloses a composite lubricant additive agent for drawing a copper tube, and a preparation method. The composite lubricant additive agent is basically composed of a fluxing solvent, an oiliness agent, an extreme pressure agent, an antirusting agent, a corrosion inhibitor, a brightener and an anti emulsifier. The lubricant oil prepared by additive agent compounds can ensure the accuracy of the metal processing surface and can ensure that lubricant oil residue on the processing surface can purify and volatilize but has no trace in the process of protective atmosphere annealing when the copper is drawn.
Description
The present invention relates to a kind of lubricating oil additive, particularly relate to a kind of composite lubricant additive for drawing copper tubes and preparation method thereof.
As everyone knows, copper processing belongs to the plastic working category, and is different with steel processing, for example do not need high extreme pressure property but wear-resistant and antifriction quality are had relatively high expectations.Being engaged in metal processing has different requirements with the producer of equipment lubrication to lubricating oil, for example requires it colourless, tasteless or the like.Domestic non-ferrous metal processing and Study on Lubrication are got seldom, gratifying lubricating oil is less.The factory of at present domestic several copper drawings mainly is distributed in ground such as Shanghai, Beijing, Jinan, Shenyang.Owing to the drawing oil quality problems of using do not make the test specimen precision of processing high or annealing property is bad, processing test specimen quality problems happen occasionally.It is the smaller the better that drawing copper tubes is crossed range request contact surface frictional coefficient, but in the course of processing, friction pair mainly is in boundary lubrication condition, because non-ferrous metal is softer, therefore viscous deformation is easy, needs lubricating oil to have suitable oil film strength and antifriction performance preferably.
The purpose of this invention is to provide the lubricating requirement that a kind of drawing copper tubes lubricating oil additive satisfies drawing copper tubes.
Another object of the present invention provides a kind of drawing copper tubes preparation process lubricant oil additive.
Composite lubricant additive for drawing copper tubes of the present invention, it is made up of diluting solvent, pour point depressant, brightening agent, oiliness improver, extreme pressure agent, antirust and corrosion inhibitor, antioxidant, non-emulsifying agent basically.
Diluting solvent of the present invention is alkane or lighting end mineral oil.
Pour point depressant of the present invention is wherein a kind of of polyacrylic ester, polyalphaolefin, vinyl acetate between to for plastic-divinyl two acid esters.
Brightening agent of the present invention is the Fatty Alcohol(C12-C14 and C12-C18) of carbon atom 12～18.
Oiliness improver of the present invention is a kind of in Laurate ethyl, butyl stearate, Laurate methyl, palmitinic acid formicester, the palmitinic acid fourth fat.
Extreme pressure agent of the present invention is tritolyl phosphate or di-n-butyl phosphite.
Antirust and corrosion inhibitor of the present invention is 124 Triazole fatty amine salt or alkenyl succinic acid.
Non-emulsifying agent of the present invention is polyethylene oxide-propylene oxide or polyethylene oxide ether.
Antioxidant of the present invention is benzotriazole or thiadiazoles.
The present invention is made up of alkane or lighting end mineral oil 20～70%, pour point depressant 0.5～20%, brightening agent 5～25%, oiliness improver 5～30%, tritolyl phosphate or di-n-butyl phosphite 6～30%, 124 Triazole fatty amine salt or alkenyl succinic acid 0.01～5%, benzotriazole or thiadiazoles 0.01～0.5%, polyethylene oxide-propylene oxide or polyethylene oxide ether 0.01～5% basically.
Its carbonatoms of the said alkane of the present invention is 8～22.
The preparation method of composite lubricant additive for drawing copper tubes is with alkane or lighting end mineral oil 20～70%, pour point depressant 0.5～20%, brightening agent 5～25%, oiliness improver 5～30%, tritolyl phosphate or di-n-butyl phosphite 6～30%, 124 Triazole fatty amine salt or alkenyl succinic acid 0.01～5%, benzotriazole or thiadiazoles 0.01～0.5%, polyethylene oxide-propylene oxide or polyethylene oxide ether 0.01～5% add in the mediation still of belt stirrer, slowly be heated to 100 ℃, be incubated 1 hour, the cooling back is continued at room temperature to be stirred to all materials and is dissolved transparent fully.
The present invention compared with prior art has following substantive distinguishing features:
(1) machined surface quality height can keep the smooth of finished surface and have peace and quiet annealing performance,
(2) adopt low-viscosity oil, volatility is good, can not save degreasing process at residual lubricating oil of workpiece surface or ester class thing, guarantees that promptly there is not residuals in the surface after the processing;
(3) has certain oil film strength.
In order to estimate the performance of composite lubricant additive for drawing copper tubes, carried out following test: (1) lubricating oil to preparation on four ball experimental machine has carried out oil film strength and long term wear test, estimates the friction and wear behavior of lubricating oil.(2) on the SRV friction wear testing machine copper alloy is carried out frictional coefficient and wearing and tearing mensuration: (load 50N, frequency 25Hz, amplitude 1mm, room temperature), on the performance of lubricating oil, frictional coefficient and wearing and tearing should be the smaller the better.(3) volatility test: the 50mg oil product is sprayed on the copper coin of 100mm * 100mm, under steady temperature, measures copper coin weight, extrapolate evaporation rate from the copper coin changes in weight; Heat and do the volatility test, the 50mg oil product is sprayed on the copper coin of 100mm * 100mm, put into loft drier,, under 180 ℃ of conditions, investigate its volatility respectively at 80 ℃.
Used temperature is degree centigrade among the present invention, and used percentage ratio (%) is weight percentage.
In carrying out assessment of performance in 1% the ratio adding base oil, the result is as follows with above complex additive of the present invention:
