Definitions

  • the present invention relates to a new means for inhibiting aqueous corrosion belonging to the family of fluorophosphates, for protecting metallic surfaces, in particular those of installations and devices using water as energetic or thermal fluid.
  • the invention also relates to a composition containing this means in combination, where appropriate, with one or more other substances useful in the field of protection against aqueous corrosion.
  • any metallic surface of current industrial use and that any material composed of one or more metals, such as iron and its alloys, in particular galvanized steel, copper and its alloys, aluminum and its alloys , to cite only the most used, are subjected, in contact with water, to corrosion phenomena which are all the more significant and cumulative as the additions of new water are themselves frequent, or significant in quantities in the installations, networks or devices using water as energy or thermal fluid.
  • metals such as iron and its alloys, in particular galvanized steel, copper and its alloys, aluminum and its alloys
  • FR-A-2 192 192 and FR-A-2 231 777 which use an inhibiting composition comprising in combination (i) an orthophosphate, ie a non-fluorinated phosphate, and (ii) a derivative of water-soluble organophosphonic acid or a polymer such as polyacryl- amides, polyacrylic acids and polyacrylates.
  • fluorophosphates also designated by the expression “oxyfluorinated phosphorus derivatives 5" are known substances, in particular from FR-A-2 352 895, as means for treating metal surfaces before painting.
  • a new technical solution is recommended, to solve the problem of protecting metal surfaces from aqueous corrosion, which uses new inhibitory means structurally different from the means previously known in the field of inhibiting corrosion.
  • This new technical solution is particularly advantageous for protecting against metal corrosion the metallic surfaces of installations, networks and devices using liquid water (raw water, demineralized water, synthetic water, industrial water which may in particular contain an antifreeze. , salt water such as sea water, aqueous mud in particular for oil drilling, etc.) as an energy or thermal fluid (cooling or heating circuits).
  • liquid water raw water, demineralized water, synthetic water, industrial water which may in particular contain an antifreeze.
  • salt water such as sea water, aqueous mud in particular for oil drilling, etc.
  • thermal fluid cooling or heating circuits
  • the corrosion inhibiting means preferred according to the invention are the zinc and potassium fluorophosphates, namely ZnPO 3 F and K 2 PO 3 F, the most interesting means being ZnPO 3 F.
  • the fluorophosphates according to the invention are substances generally not very water-soluble, the solubility threshold in water being of the order of 10 g / 1.
  • an aqueous corrosion inhibiting composition which is characterized in that it contains in aqueous solution or suspension a corrosion inhibiting means chosen from all of the fluorophosphates of the points ( i) to (viii) above.
  • This composition is used in such a way that, after introduction into the corrosive aqueous fluid, the content of the inhibitor means is from 3 to 500 ppm by weight (preferably 5 to 200 ppm by weight, in particular for ZnP0 3 F) relative to the weight of the fluid.
  • the amines of formula I can be used as they can be obtained commercially, alone or mixed together, in their pure or technical forms.
  • polyamines sold which are suitable mention may be made in particular of the products known under the brand names DUOMEEN, DINORAM, TRINORAM, POLYRAM, LILAMIN and CEMULCAT which contain at least one polyamine I.
  • DINORAM 0 which 'contains approximately 75% by dry weight of oleylamino-propylene amine, 9% by dry weight of stearylaminopropyleneamine and 6% by dry weight of hexadecylaminopropyleneamine
  • DINORAM S which contains approximately 43% by dry weight of stearylinopropyleneamine , 28% by dry weight of oleylaminopropyleneamine and 28% by dry weight of hexadecylaminopropyleneamine, these products being marketed by the company CECA.
  • the polymeric organic polyelectrolytes having a molecular weight greater than or equal to about 150 and preferably a molecular weight greater than or equal to 300 are recommended.
  • the upper limit of the molecular weight can be very high and in particular of the order of 2,000,000 or more.
  • the polyelectrolytes which are suitable mention may in particular be made of the polymers and copolymers obtained from acrylic acid, its esters and its salts, methacrylic acid, its esters and its salts, acrylamide, methacrylamide, acid maleic, its esters and its salts.
  • these polyelectrolytes are polymeric substances obtained by polymerization, copolymerization or terpolymerization starting from a monomer which can be schematically represented by the formula in which M 1 , M 2 , M 3 or M 4 , which may be identical or different, each represent the hydrogen atom, a C 1 -C 4 alkyl group, nitrile, aldehyde, alcohol, amine, amide, imine, imide, ammonium, CO 2 H or SO 3 M (wherein M is H, lkyle a C 1 -C 4, NH 4 + or a metal cation, in particular Na + or K +).
  • a method for protecting metallic surfaces in contact with water from aqueous corrosion and in particular those of installations using water as an energetic or thermal fluid.
  • This process comprises the introduction into the corrosive aqueous fluid of an amount of corrosion inhibiting fluorophosphate such that, after introduction into said fluid, the fluorophosphate content is between 3 and 500 ppm by weight relative to the weight of said fluid.
  • the corrosion inhibiting fluorophosphate is ZnP0 3 F
  • the content of ZnP0 3 F, after introduction into said corrosive fluid will be between 5 and 200 ppm by weight relative to the weight of the corrosive aqueous fluid.
  • the products of Examples 1 and 2 are put into the form of aqueous compositions by suspending ZnPO 3 F or K 2 PO 3 F in water; use a composition containing 12 g / 1 of ZnP0 3 F or K 2 PO 3 F which is diluted at the time of use in the corrosive medium.
  • the products of Examples 3 - 7 are prepared by introducing ZnPO 3 F into the mixture of the two other means, said mixture having been obtained according to the methods described in the European patent and the above-mentioned European patent application.
  • the products of Examples 8-10 are prepared by introducing into water ZnPO 3 F or K 2 PO 3 F with polyacrylic acid or potassium aminotrimethylenephosphonate.
  • the products of Examples 1, 3 and 6 are injected into the annular space of a steel oil well operating by pumping and having a length of 2500 meters into the aqueous mud so that the content of the products of the said examples is between 20 and 150 ppm. It can be seen that the corrosion rate expressed in ⁇ / year is considerably reduced with the products of Examples 1, 3 and 6 compared with the control (injection of aqueous mud only).
