Definitions
- the subject of the invention is plugs based on polymers and one of the components of which consists of a composition or premix based on volatile corrosion inhibitors.
- plugs any part capable of obstructing the opening of a hollow part, such as plugs, capsules, threaded bodies, used for the localized volatile corrosion protection of certain internal parts, hollow metal parts.
- the constituent material of the caps which is based on polymers and one of the components of which is a composition or premix based on volatile corrosion inhibitors, has been used to prepare packaging articles.
- the LCIs are incorporated into the material constituting these films; since these films can be in contact direct with the surface of the parts to be protected, corrosion inhibitors acting on contact are also incorporated into the constituent mass of these films.
- Volatile corrosion inhibitors offer, under these conditions, very good protection against corrosion and have the advantage of making it possible to avoid having to resort to conventional techniques for protecting metal parts; these conventional techniques consist in the application of paints, varnishes, plastics, waxes, greases and oils which must be removed before finishing on site, which leads to additional costs and pollution.
- Volatile corrosion inhibitors generally designated by ICV, use additives whose vapor pressure can be considered to be non-negligible at the temperature of use (for example, of the order of 10 "5 to 10 " 1 mm Hg, at 20 ° C), which are capable of inhibiting corrosion of metals.
- LCIs act thanks to the fact that they are transported in the form of vapor to the metal surface to be protected, to be adsorbed there or else dissolved in a possible water of condensation.
- Products are also known which are classified by extension in the LCIs due to the fact that one of their reaction products has an adequate vapor pressure.
- sodium nitrite in the presence of ammonium ions, can form ammonium nitrite which is relatively volatile.
- the starting sodium nitrite is then considered as an LCI. It is sometimes necessary to protect against corrosion only internal parts of hollow metal parts of large dimensions and complex geometry, in particular cavities, threaded parts or tubular holes. Stoppers according to this invention, based on polymers and possibly other structuring agents, shaped by the usual techniques of the polymer industry (extrusion, injection, thermoforming) allow to obstruct the openings of metal parts and provide them with the necessary localized protection, considerably minimizing costs.
- LCIs At the extrusion temperature which is around 160 ° C for low density polyethylene and 240 ° C for polypropylene, LCIs have an extremely high volatility which leads, in the case of thin articles, to appearance of a high porosity and a high risk of degradation and / or decomposition with elimination of at least part of the LCIs. The anticorrosion effectiveness of such articles is therefore greatly reduced as a result of the loss of active ingredients.
- premixes containing the ICVs that is to say to active ingredient concentrates dispersed in carriers such as polymers, solvents and plasticizers; premixes based on polymers (Patent BR-A-9001035) have the general advantage of being homogeneous and easy to handle; these premixes are then incorporated into the polymers for the preparation of the articles.
- the temperatures used when preparing the premixes are often greater than 150 ° C., there is at least partial degradation of said premixes; so and as for example, it is reported that the dicyclohexy nitrite laminate, mixed and extruded with polyethylene at 160 ° C., leads to premix granules which have a dark yellow coloration, characteristic of a strong degradation, that is to say say of a loss of activity.
- the object of the invention is to provide plugs based on polymers using at least one composition. based on ICV responding better than those that already exist to the various desiderata of the practice.
- the invention also aims to propose new uses for these stoppers based on ICV, such as partial and localized protection of certain internal parts of hollow metallic parts.

- a composition based on volatile corrosion inhibitors which comprises an effective amount of at least one structuring agent, consisting by a solid or pasty substance whose melting point is from 40 to 110 ° C, preferably from 50 to 90 ° C, whereby the release and / or degradation of the LCIs at the time of the formation of the composition or premix is limited to the maximum.
