Description

Die Erfindung betrifft ein zellstoffbasiertes, dreidimensionales Korrosionsschutz-Formteil nach dem Oberbegriff des Anspruchs 1.The invention relates to a cellulose-based, three-dimensional corrosion protection molding according to the preamble of claim 1.

Alle Maßnahmen des temporären Korrosionsschutzes für Metalle gegen die Einwirkung neutraler wässriger Medien oder kondensierter Wasserfilme haben bekanntlich das Ziel, die auf Gebrauchsmetallen nach erstem Kontakt mit der Atmosphäre stets vorhandene Primäroxidschicht (primary oxide layer, POL) vor chemischem und mechanischem Abbau zu konservieren (vgl. z. B.: E. Kunze (Hrsg.), Korrosion und Korrosionsschutz, Band 3, Wiley-VCH, Berlin, Weinheim, New York 2001, S. 1680 ff.).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. For example: E. Kunze (ed.), Corrosion and corrosion protection, Volume 3, Wiley-VCH, Berlin, Weinheim, New York 2001, p 1680 ff.).

Unterschiedliche temporäre Korrosionsschutzmethoden sind aus der Praxis grundsätzlich bekannt. Während der Lagerung und Transporten von metallischen Erzeugnissen finden diese Anwendung. Eine Möglichkeit des temporären Korrosionsschutzes ist der Einsatz von „Volatile Corrosion Inhibitor (VCI)“ oder „vapour phase corrosion inhibitor (VpCI)“ genannten Verbindungen, die übliche Gebrauchsmetalle, wie Eisen, Chrom, Nickel, Zinn, Zink, Aluminium, Kupfer, Magnesium und deren Legierungen vor Korrosion schützen. Aufgrund der Verdampfungseigenschaften der VCI bzw. VpCI gehen diese in die Gasphase über, um auf der metallischen Werkstoffoberfläche eine schützende Adsorptionsschicht aufzubauen, wodurch der direkte Kontakt des Wasserdampfes aus der Umgebungsatmosphäre unterbunden, elektrochemische Prozesse durch die Anwesenheit von Dampfphasen-Korrosionsinhibitoren gehemmt und die Korrosionsreaktionen stark verlangsamt bzw. ganz gestoppt werden.Different temporary corrosion protection methods are basically known from practice. During storage and transportation 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, thereby preventing the direct contact of the water vapor from the ambient atmosphere, inhibited electrochemical processes by the presence of vapor phase corrosion inhibitors and the corrosion reactions strong slowed down or completely stopped.

Korrosionsinhibitoren, die bereits unter Normalbedingungen zur Verdampfung oder Sublimation neigen, werden bereits seit mehreren Jahrzehnten als temporärer Korrosionsschutz von Metallgegenständen innerhalb von geschlossenen Räumen, z. B. in Verpackungen eingesetzt. So werden beispielsweise in den Dokumenten 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 und DE 10 2007 059 726 A1 unterschiedliche Varianten vorgeschlagen, in denen Dampfphasen-Korrosionsinhibitoren kontinuierlich aus Kapseln, Beschichtungen oder Kunststoff-Folien verdampfen oder sublimieren können. Auch die Anwendung in Korrosionsschutz-Ölen sind in den Dokumenten US 3,398,095 und US 3,785,975 beschrieben.Corrosion inhibitors, which already tend to evaporate or sublimate under normal conditions, have been used for several decades as temporary corrosion protection of metal objects within closed spaces, e.g. B. used in packaging. 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.

Gitterfacheinsätze oder Gefache werden zum Schutz von kleinen, empfindlichen Bauteilen in eine größere Verpackung u.a. in der Automotive- und Maschienenbaubranche eingesetzt. Diese können durch Ummantelung der Packgüter mit VCI haltigen Packmitteln vor Korrosion geschützt werden. Ein verbesserter Schutz vor mechanischen Transportschäden der Packgüter können mit individuell angefertigten, den Anforderungen entsprechenden zellstoffbasierten Formteilen erreicht werden. Auch kann durch eine zusätzliche Ummantelung der Packgüter mit VCI-haltigen Packmitteln ein Korrosionsschutz gewährleistet werden. In der vorliegenden Erfindung wird das Formteil mit VCI Wirkstoffen ausgebildet. Auf zusätzliche VCI haltige Packmittel kann verzichtet werden, wodurch Ressourcen geschont werden.Lattice trays or compartments are used to protect small, delicate components in a larger package, among others. used in the automotive and engineering industry. These can be protected from corrosion by sheathing the packaged goods with VCI-containing packaging. Improved protection against mechanical transport damage to the packaged goods can be achieved with individually manufactured, fabric-based molded parts that meet the requirements. Also can be ensured by an additional sheathing of packaged goods with VCI-containing packaging corrosion protection. In the present invention, the molding is formed with VCI agents. Additional VCI-containing packaging can be dispensed with, which saves resources.

Es kann vorgesehen sein, dass die zellstoffbasierten Formteile als Kopf-, Zwischen-, Seiten-, Eck- oder Bodenelemente ausgebildet sind.It may be provided that the pulp-based molded parts are designed as head, intermediate, side, corner or bottom elements.

Es kann vorgesehen sein, dass die zellstoffbasierten Formteile ergänzt mit weiteren Eigenschaften wie z.B. nicht brennbar, wasserabweisend oder flüssigkeitsdicht ausgebildet sind.It may be provided that the pulp-based molded parts supplemented with other properties such as. are not flammable, water-repellent or liquid-tight.

Bei der Herstellung von zellstoffbasierten Formteilen wird eine Mischung bestehend aus Papierfasern, Wasser, Korrosionsschutzmittel und weiteren Additiven wie z.B. Industriestärke per Spritzgussverfahren in ein Werkzeug gespritzt und unter Hitzeeinwirkung gebacken. Alternativ können die Korrosionsschutzmittel auch nach dem Backen dem zellstoffbasierten Formteil zugesetzt werden.In the production of pulp-based moldings, a mixture consisting of paper fibers, water, corrosion inhibitors and other additives such as e.g. Industrial starch injected by injection molding into a tool and baked under heat. Alternatively, the corrosion inhibitors may also be added after baking to the pulp-based molded part.
