Description

The invention relates to a corrosion protection dispenser consisting of a housing ( 1 ), filled with anticorrosion agent ( 6 ), preferably low- to high-viscosity liquids, oils, waxes, gels, pasty or semi-solid materials which release volatile, corrosion-inhibiting active ingredients (VCI, VpCl), for the protection of corrosion-prone objects made of metal.

All measures of temporary corrosion protection for metals against the action of neutral aqueous media or condensed water films are known to preserve the primary oxide layer (primary oxide layer, POL) that is always present on the working metals after initial contact with the atmosphere from chemical and mechanical degradation (cf. eg: E. Kunze (Ed.), Corrosion and Corrosion Protection, Volume 3, Wiley-VCH, Berlin, Weinheim, New York 2001, p. 1680 et seq. ).

Different temporary corrosion protection methods are basically known from practice. During storage and transports of metallic products find this application. One possibility of temporary corrosion protection is the use of "Volatile Corrosion Inhibitor (VCI)" or "vapor phase corrosion inhibitor (VpCI)" compounds, the usual utility metals, such as iron, chromium, nickel, tin, zinc, aluminum, copper, magnesium and their alloys protect against corrosion. Due to the vaporization properties of the VCI and VpCl, these go into the gas phase to build on the metallic material surface, a protective adsorption layer, whereby the direct contact of the water vapor is prevented from the ambient atmosphere, electrochemical processes inhibited by the presence of vapor phase corrosion inhibitors and the corrosion reactions slowed down or completely stopped.

Corrosion inhibitors, which are prone to evaporation or sublimation under normal conditions, have been used for several decades for the temporary corrosion protection of metal objects within enclosed spaces, e.g. B. in packaging, cabinets or showcases used. For example, in the documents US 3,836,077 . US 3,967,926 . US 5,332,525 . US 5,393,457 . US 4,124,549 . US 4,290,912 . US 5,209,869 . EP 0 639 657 A1 . EP 1 219 727 A2 and DE 10 2007 059 726 A1 proposed different variants in which vapor phase corrosion inhibitors can evaporate or sublime continuously from capsules, coatings or plastic films. Also the application in corrosion protection oils are in the documents US 3,398,095 and US 3,785,975 described.

Existing vapor phase corrosion protection dispensers for packaging consist of powder, granules, compressed tablets, or coated pulp-based products, e.g. T. be packaged in gas-permeable containers, such as paper, non-woven bag or plastic capsule.

The object of the invention is to provide an improved anticorrosive dispenser, which is distinguished by better corrosion protection properties and by the use of preferably harmless chemicals according to TRGS 900 for the best possible protection of the end user. By eliminating carrier materials for incorporation of the vapor phase inhibitor environmental aspects are also considered.

The object and purpose of the invention is described in the main claim 1. This is a corrosion protection dispenser for use in enclosed spaces, eg. As in packaging, cabinets or showcases, for the indirect corrosion protection of common utility metals such as iron, chromium, nickel, tin, zinc and their alloys, consisting of a housing ( 1 ) with a housing opening ( 4 ), filled with anticorrosion agent ( 6 ). It is essential that the corrosion protection agent ( 6 ), preferably low to high viscosity liquids, oils, waxes, gels, pasty or semi-solid materials, except gelling or thickening agents, organic compounds, oils and / or waxes no further carrier material based on pulp or polymer needs.

It may be provided that, if present, the opening (s) ( 4 ) is / are designed so that a metered release of the active ingredient is possible.

It can be provided that as a cover of the housing opening ( 4 ) removable and / or reusable covers ( 7 ) formed of a material impermeable to the drug.

It can be provided that to cover the housing opening (s) ( 4 ) can be used attachable, weldable, unscrewable, as well as aufschiebare versions, which close the opening / en or release.

It may be provided to fill or cover the opening in the housing by a material. The material, a membrane and / or a filter material ( 5 ), can be arranged in the region of the opening (s) inside or outside the housing, which prevents leakage of the corrosion inhibitor. It is essential that the vapor phase of the anticorrosive active ingredient in use can be continuously discharged to the environment. The membrane and / or the filter material ( 5 ) can be chosen in its nature so that the release of the vapor phase inhibitor is favored or accelerated.

It can be provided that the housing body ( 3 ) a housing cover ( 2 ), which can be plugged, glued on, welded, screwed, as well as pushed or with a joint or a clip connection for connection to the housing ( 1 ) is trained.

It can be provided that the housing cover ( 2 ) itself from a membrane and / or a filter material ( 5 ) is trained.

It can be provided that the housing opening ( 4 ) in the housing body ( 3 ) and / or on the housing lid ( 2 ) is arranged.

It can be provided that on the housing ( 1 ) Projections for attaching or hooking and / or Velcro fasteners, magnets and adhesive surfaces for attachment to the housing ( 1 ) are formed.

Three possible embodiments of the vapor-phase corrosion protection dispenser according to the invention ( 1 ) are under 1 to 8th shown. This consists in the first case ( 1 to 5 ) from a housing ( 1 ), divided into housing cover ( 2 ) and housing body ( 3 ). The housing is preferably with low to high viscosity liquid, oil, wax, gel, pasty or semi-solid material as a corrosion inhibitor ( 6 ). Through the opening ( 4 ) the active ingredient diffuses out of the housing ( 1 ) into the environment, within a common space and outside the enclosure ( 1 ) arranged, partially or completely made of metallic material articles, to protect against corrosion.

In the second embodiment ( 6 ) is the housing body ( 3 ) with a membrane and / or a filter material ( 5 ) and cover ( 7 ). The housing is preferably with low to high viscosity liquid, oil, wax, gel, pasty or semi-solid material as a corrosion inhibitor ( 6 ). Through the membrane and / or the filter material ( 5 ) the active ingredient diffuses out of the housing ( 1 ) into the environment, within a common space and outside the enclosure ( 1 ) arranged, partially or completely made of metallic material articles, to protect against corrosion.

In the third embodiment ( 7 and 8th ) is the opening ( 4 ) of the housing ( 1 ) filled with a membrane and / or a filter material ( 5 ). The housing is preferably with low to high viscosity liquid, oil, wax, gel, pasty or semi-solid material as a corrosion inhibitor ( 6 ). Through the membrane and / or the filter material ( 5 ) the active ingredient diffuses out of the housing ( 1 ) into the environment, within a common space and outside the enclosure ( 1 ) arranged, partially or completely made of metallic material articles, to protect against corrosion.

In order to prevent leakage of the anti-corrosion agent in liquid form, the openings ( 4 ) of the housing cover ( 2 ) through a filter material layer or membrane layer ( 5 ) (see 3 ). The membrane and / or the filter material ( 5 ) prevent leakage of the protective solution and / or accelerate the release of the corrosion inhibitor into the gas phase from the housing ( 1 ). Depending on the viscosity of the anticorrosion agent, the corrosion protection dispenser can also be used without the use of the membrane or filter material ( 5 ) be formed.

In order to prevent inadvertent release of the active substance from the housing ( 1 ), the openings ( 4 ) through a cover ( 7 ) locked. They are removable and / or reusable covers ( 7 ), as well as clip-on, glued on, weldable, hinged, screw-on and postpone versions of the cover can be formed, which are opened partially or completely if necessary, to allow a metered release of the anticorrosive active ingredient in the environment.

On the housing ( 1 ) projections, not shown in the figures for attaching or hooking and / or hook and loop fasteners, magnets and adhesive surfaces are designed for attachment.
