The pure water base plate strip steel rolling liquid that contains nanometer silver
Technical field
The present invention relates to a kind of soluble oil that is used for the strip steel rolling.
Background technology
In Iron And Steel Industry and non-ferrous metal processing, rolling is to utilize roll metal stock to be rolled into the processing mode of the sheet material of all size.Can be processed into difform material to steel, copper, aluminium etc. by rolling processing.Need use a large amount of rolling lubricants when rolling and cool off and lubricate, improve the quality of products and protect roll.
The effect of rolling lubricant is: reduce frictional coefficient and frictional force on the distorted area contacting surface, reduce the wearing and tearing of roll, to the wetting action of rolled piece, prevent that on the rolled piece surface intermetallic from sticking together, thereby improve calendering efficient; Cooling effect is to take away the fricative a large amount of heat in metallic surface in the operation of rolling, makes the mechanical property of metal and surface shape unaffected.
At present, rolling lubricant has types such as oil type ROLLING OIL and emulsion aq. type lubricant.The oil type lubricant has good lubricating effect, but cooling performance is poor slightly, also exists inflammable and shortcoming contaminate environment.The solubility liquid (claiming emulsion again) that the emulsion aq. type is commonly used is made up of mineral oil (or vegetables oil), water, emulsifying agent, additive.It had both had the good advantage of oil type lubricant oilness, had the well behaved advantage of water cooling again, also reduced the danger of catching fire in the lubricant use simultaneously.Weak point be gone bad by microbial contamination easily, corrupt, influence its work-ing life.

In the described water-soluble nano silver water-sol, the median size of silver particles is 10~50 nanometers, and the weight content of silver particles is 0.5~1.0%, preferably 1.0%;
The described water-soluble nano silver water-sol, the method that can provide with reference to following document is prepared:
(1) Zhao Bin, Yao Ming be virtuous etc. " control of the particle diameter of silver particles in the silver-colored ultrafine particle dispersed liquid ", " petrochemical complex " 1996,25 (3), 159;
(2) " preparation of the copper ultrafine particle dispersed liquid of polymer protection " " petrochemical complex " 1993,22 (3), 159 of Zhao Bin, Gao Zongming etc.;
(3) ZL00111402.2, bimetal Cu-Ag colloid as antibacterial agent and preparation method thereof.
The water-soluble anti-rust inhibiter is phenylpropyl alcohol triazole, tetrahydroglyoxaline or is 15~40% the 2-amino-2-methyl-1-propanol aqueous solution for containing weight percent, or contain the aqueous solution that weight percent is the polycarboxylic acid of 20-50%, as above the dried shrimps woods chemistry company limited trade mark is the product of CP-35;
Dispersion agent is selected from more than one in Polyvinylpyrolidone (PVP) (PVP), polyvinyl alcohol, methylcellulose gum, Natvosol or the gelatin;
Defoamer is three-dimensional siloxanes or polyether antifoam agent, and it is the product of 3529B that three-dimensional siloxanes can adopt the quick oil product chemistry of the think of company limited trade mark;
Preferably, the described pure water base plate strip steel rolling liquid that contains nanometer silver, form by following components in weight percentage:
Further preferred, the described pure water base plate strip steel rolling liquid that contains nanometer silver, water-soluble steel plate rolling liquid is made up of following components in weight percentage:
The preparation that contains the pure water base plate strip steel rolling liquid of nanometer silver of the present invention is the method for the physical mixed of routine, each component is mixed to stir getting final product.
The invention has the beneficial effects as follows: the present invention adopts the water-soluble extreme pressure anti-wear additives and the water-soluble nano silver water-sol, main component as water-soluble strip steel rolling liquid, the contriver finds, the water-soluble nano silver water-sol, be a kind of extreme pressure anti-wear additives, have anti-microbial property again, therefore, the technology that solved is in strip steel rolling process, and that ROLLING OIL consumes is high, contaminated with oil mist is serious, the microbial contamination of emulsion, rotten, corruption and exhaust emission environmental problem.The present invention is oil-containing and emulsifying agent not, and with water for oil, cost reduces, and has good germ resistance again, the performance that contains the pure water base plate strip steel rolling liquid of nanometer silver of the present invention reaches the service requirements of strip steel rolling, and the practical function of environmental protection is arranged; Be convenient to industrialization.The pure water base plate strip steel rolling liquid that contains nanometer silver of the present invention also can be applied to rig bed, grinding machine and the high industry of other cooling and lubricating performance requriementss.
