Abstract
The present invention relates to an emulsion for rolling copper and copper alloy and a preparation method thereof. A new process emulsible oil formulation is adopted. In the formulation, mineral oil with middle and low viscosity is used predominantly, and a proper quantity of chemical reagents with corrosion prevention is added. The emulsible oil comprises the main components of 10 to 20% of 32# universal machine tool hydraulic oil, 50 to 70% of 7# machine oil, 5 to 10% of petroleum sodium sulfonate, 10 to 20% of O to 10 emulsifier and 5 to 10% of 7# technical white oil. The emulsible oil is prepared by stirring, heating and mixture, and then, the emulsible oil which is prepared is added to deionized water with the concentration of 90 to 97% according to bloom conditions or middle rolling conditions; the deionized water is stirred, diluted and heated continuously, and finally, the emulsion with the concentration of 3 to 10% is prepared and is suitable for rolling the copper and the copper alloy. The emulsion has good cooling and lubrication performance, and assures that the surface of a rolled belt material is smooth, and the plate profile is level.
Description
Technical field:
The present invention relates to non-ferrous metal processing and lubrication technical field, the preparation method of a kind of copper and copper alloy emulsion for rolling.
Technical background:
At present, ununified standard during each copper processing enterprise emulsion for rolling of the whole nation uses does not have ready-made alternative emulsion.Because the emulsion for rolling demand is less, only there is 1 tame emulsion allotment enterprise in the domestic enterprise that does not have the professional production emulsion, and most of copper processing enterprise all is own preparation emulsion, but unstable properties, to producing and quality product influences bigger.
Abroad: the major vendor of professional production ROLLING OIL is Esso-Mobil Corp..The said firm's oil product has operational characteristic preferably, enjoy higher prestige in the whole world, but price is up to 35800 yuan/ton.
Because the technology emulsion is oil in water emulsion to be added in a large amount of water be configured to.Because water in the existence on copper material surface, very easily causes copper strip surface corrosion variable color, simultaneously because some composition emulsifying dispersivity is difficult stable, rolling after annealing volatilization not exclusively easily in the residual spot of strip surface, influences quality product in use; In the conventional emulsification liquid formula band is had corrosive composition, as: oleic acid, trolamine etc.
By the applicant's application formerly, application number is: 200410029838.X, name is called: the patent of invention of " rolling special-purpose lubricating fluid of a kind of copper and copper alloy and compound method thereof ", and it discloses and has a kind ofly mixed with 32# all-purpose engine oil 10～20%, 7# all-purpose engine oil 50～70%, petroleum sodium sulfonate 5～10%, emulsifying agent 10～20%, white oil 5～10% proportionings; In the preparation of lubricating fluid, at first in 32# all-purpose engine oil, add 7# all-purpose engine oil, add the oil yellow acid and then and receive, add emulsifying agent again, add the 15# white oil again; Ceaselessly stir in preparation and heat, heating and temperature control is between 30 ℃-50 ℃; Add deionized water again and ceaselessly stir or circulate dilution and heating according to rolling condition again, heating and temperature control is mixed with certain density emulsion at last and is rolled between 30 ℃～50 ℃.
Summary of the invention:
In order to solve as above existing problem, the invention provides a kind of preparation method, make it have good cooling and lubricity, owing to the mineral oil chemical stability is good, realize the stable rolling of band, be difficult for wearing out, work-ing life is than superiority such as length.
For achieving the above object, the present invention adopts following technical scheme:
The preparation method of described copper and copper alloy emulsion for rolling at first is mixed with oil in water emulsion, oil in water emulsion based in, low viscous mineral oil, add an amount of chemical reagent with antiseptic property; This emulsification main body of oil is: 32# general-purpose machine hydraulic efficiency oil 10-20%, 7# machinery oil 50-70%, petroleum sodium sulfonate 5-10%,, O-10 emulsifying agent 10-20%, 7# industrial white oil 5-10%; At first add 32# general-purpose machine hydraulic efficiency oil, add the 7# machinery oil more respectively, petroleum sodium sulfonate, O-10 emulsifying agent, 7# industrial white oil toward container; Wherein in the preparation of oil in water emulsion, use agitator ceaselessly to stir, and insert electricradiator and carry out the temperature control heating, churning time is 30～60 minutes, and heating and temperature control is between 30 ℃～50 ℃; The emulsification fluid that is hybridly prepared into is brown homogeneous transparent shape; The oil in water emulsion for preparing according to kicker spare handle in the breaking down conditioned disjunction is added the deionized water based on emulsion total amount 90～97% then, and continue to use ceaselessly agitation and dilution and insert electricradiator and carry out the temperature control heating of agitator, churning time is 120～240 minutes, heating and temperature control is between 30 ℃～50 ℃, finally be mixed with consoluet emulsion and be even oyster white, concentration be 3～10% be suitable for copper and copper alloy emulsion for rolling.
The preparation method of described copper and copper alloy emulsion for rolling, the O-10 emulsifying agent of its emulsify well that is integrated with water is a fatty alcohol-polyoxyethylene ether, the polymerization degree is 10, is that Fatty Alcohol(C12-C14 and C12-C18) and oxyethane are that catalyzer addition, condensation form with sodium hydroxide;
The preparation method of described copper and copper alloy emulsion for rolling, the preparation 32# general-purpose machine hydraulic efficiency oil that oil in water emulsion adopted is with the distillate of crude oil through underpressure distillation, again through Tuo La and suitably the neutral oil of refining gained be base oil, add the general-purpose machine hydraulic efficiency oil that additives such as antioxygen, antirust and anti-bubble are made;
The preparation method of described copper and copper alloy emulsion for rolling, petroleum sodium sulfonate is a raw material with middle light machine oil, through reacting with oleum or sulphur trioxide, separate acid sludge and free sulphur trioxide, gained sulfonic acid neutralizes with sodium hydroxide, with ethanol-water solution extraction neutralized reaction product, remove inorganic salt through de-oiling, washing, dehydration is made again.
The preparation method of described copper and copper alloy emulsion for rolling, the 7# industrial white oil is raw material with crude oil through the distillate of underpressure distillation, more colourless, the tasteless oily liquids that forms through Tuo La and chemical refining or hydrofining.
The preparation method of described copper and copper alloy emulsion for rolling, the 7# machinery oil is with the natural oil lubricating oil distillate, through Tuo La and solvent treatment or acid-alkali refining, and the standard machinery lubricating oil of making through clay treatment.
Owing to adopted technical scheme as mentioned above, the present invention has following positively effect:
Emulsion for rolling breaker roll and rolled piece do not have corrosive nature, compare with traditional emulsion, and viscosity is lower, and volatility is good, easily remove after rolling, do not stay spot after the annealing, can effectively control the copper strip surface corrosion and pollute; On the other hand, based on formulated emulsion behind the deionized water interpolation oil in water emulsion of emulsion total amount 90～97%, oilness and good fluidity are not only easily attached to rolled piece and roller surface lubricate, can take away a large amount of distortion heat by flowing again, play the effect of cooling strip material and roll, have good cooling and lubricity, realize the stable rolling of band, because the mineral oil chemical stability is good, be difficult for wearing out, work-ing life is longer, as dimension
Protect rationally, can reach half a year to one year general work-ing life.In addition, cost only is external 1/4～1/5.And breakdown of emulsion reaches emission standard easily, and environment is not polluted.
