Definitions

  • the present invention relates to a method of inhibiting the corrosion of an item by using an anhydrous amine molybdate as a vapor phase corrosion inhibitor.
  • corrodible items In commerce and industry today, the useful life of corrodible items may be extended and/or preserved by providing corrosion inhibitors which protect the corrodible item from the adverse effects of its ambient environment.
  • Corrosion inhibitors particularly vapor phase corrosion inhibitors, have been found useful in protecting certain corrodible items against reaction with elements or compounds which may be found within their environment, and thereby losing their effectiveness, reducing their useful life, or otherwise diminishing their value. Such protection is typically needed during times of packaging, handling, shipment, or during end use.
  • Elements or compounds which are normally of primary concern are gases such as oxygen, water vapor, sulfides, carbon dioxide, and the like.
  • the formulations of the present invention find particular application in the preparation of packaging material, particularly through in-situ extrusion of the material with such films, with the films thereafter forming an envelope or other enclosure about the article being protected.
  • These films may also be employed as a member of a multi-layer laminate including a metallized film having good tear resistant properties such as stress-oriented polyethylene terephthalate containing a vapor deposited film or layer of metallic aluminum.
  • Such films are commercially available and are commonly designated as "aluminized" films.
  • Solid phase and liquid phase compounds have been used in the past to provide a source of vapor phase corrosion inhibitors. These materials typically undergo either evaporation or sublimation so as to provide the substantially constant availability of the inhibitors. In other words, vapor phase corrosion inhibitors typically emit vapors which protect corrodible surfaces through the deposition or condensation of a protective film or coating upon the surface. In order to be assured that a constant supply of inhibitor be present, adequate quantities of the solid phase or liquid phase corrosion inhibiting compounds must be provided, with the corrosion inhibiting compounds being released at or adjacent the location where needed.
  • US-A-4,298,657 discloses a corrosion inhibitor that is deposited, painted or sprayed on an item which is to be protected from corrosion.
  • the inhibitor includes sodium molybdate.
  • EP-A-0,015,496 discloses the use of an amine molybdate as a smoke retardant.
  • JP-A-60071799 discloses a rust-proofing paper including a volatile rustproofing agent in the form of ammonium molybdate.
  • the present invention relates to a method of inhibiting corrosion of an item, as set out in claim 1.
  • the pre-characterising part of claim 1 is based on JP-A-60071799, and the distinguishing features of the present invention are set out in the characterising part of claim 1.
  • the present invention also relates to the use of an amine molybdate in the manufacture of an inhibitor for the purpose of vapor phase corrosion inhibition.
  • the inhibitor may be extruded with a film material such as an olefinic film, polyethylene, or the like, and placed within the confines of an enclosure housing the item being protected.
  • the inhibitor may be placed within packages containing items which are to be protected from corrosion.
  • Anhydrous mixtures of an amine molybdate along with sodium nitrite and benzotriazole are preferred for these applications, with this mixture further being preferably extruded into polyethylene film at a rate of from between about 2 percent and 3 percent by weight.
  • Film materials extruded with the inhibitor may in one embodiment, in turn, by laminated to a second metallized film, such as, for example, metallized polyethylene terephthalate.
  • a second metallized film such as, for example, metallized polyethylene terephthalate.
  • the combined laminate provides a means to reduce and/or eliminate static build-up in or along the film, and accordingly improves the properties of the film when employed as an enclosure.
  • one layer comprises a heat sealable film such as polyethylene with the inhibitor extruded in-situ, and with a second layer being a material such as metallized stress-oriented polyethylene terephthalate
  • a desirable combination of properties are achieved.
  • the polyethylene film layer retains its conventional heat sealing properties, while the stress-oriented polyethylene terephthalate provides a tear-resistant property.
  • the metallized layer is utilized to reduce and/or eliminate static build-up thereby further enhancing the properties and qualities of the laminate.
  • Stress-oriented polyethylene terephthalate is normally biaxially oriented, and is, of course, commercially available.
  • the inhibitor is particularly useful in providing protection to both ferrous and non-ferrous metals, including such non-ferrous metals as aluminum, copper and brass.
  • the vapor phase corrosion inhibitor produces little, if any, visible residue.
  • the lack of residue enhances the utility of the inhibitor inasmuch as little, if any, mechanical or electrical problems result from the continuous use of this inhibitor.
  • the inhibitor is particularly well adapted to be employed as an extrudate with films fabricated from aliphatic hydrocarbon such as polyethylene and polypropylene.
  • the inhibitor is utilized for retention and/or packaging within modestly porous envelopes or other enclosures formed of plastic film or plastic foam.
  • those certain enclosures disclosed and claimed in the Miksic et al U.S. Patents 4,051,066 and 4,275,835, as identified hereinabove, are well adapted for use with the inhibitor.
  • the vapor phase corrosion inhibitor comprises an anhydrous amine-molybdate having the general structural formula: wherein either, (i) R1 is either a 2-ethylhexyl radical or an aliphatic hydrocarbon having up to 7 carbon atoms, and wherein R2 is either hydrogen or an aliphatic hydrocarbon having up to 7 carbon atoms, or (ii) R1 and R2 and 2-ethylhexyl radicals.
  • the preferred amine molybdates are derived from the group consisting of dicyclohexylamine, 2-ethylhexylamine, and cyclohexylamine. Such molybdates are readily synthesized and can be prepared in anhydrous form without requiring unusual processing or handling problems.
  • FIG. 1 is a cross-sectional view of a typical laminate prepared in accordance with the present invention, with the center or metallized layer being shown in somewhat exaggerated form due to limitations of draftsmanship.
  • a particularly useful vapor phase corrosion inhibitor for extruded polyethylene film includes a mixture of anhydrous amine molybdates, together with sodium nitrite and benzotriazole.
