Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer hochhaftfesten Verbindung zwischen metallischem Grundmaterial und Gummiformteilen, die für schwingungs­ belastete Teile aus allen Bereichen der Technik als Schwingungsdämpfer Teile Anwendung, die aus einem metallischen Grundkörper und darauf aufgebrachten Gummiformteilen bestehen, gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a method for manufacturing a highly adhesive connection between metallic Base material and molded rubber parts for vibration loaded parts from all areas of technology as Vibration damper parts application made from one metallic base body and applied thereon Molded rubber parts exist, according to the preamble of the claim.

Stand der Technik ist es, Verbindungen zwischen metallischem Grundmaterial und Gummi nach 2 verschiedenen Varianten herzustellen.State of the art is connections between metallic base material and rubber according to 2 to produce different variants.

Variante 1Version 1

Nach dem Reinigen werden die metallischen Grundteile komplett galvanisch verzinkt bzw. gelbchromatiert bzw. zinkphosphatiert. Danach werden die Bereiche des metallischen Grundmaterials, auf denen das Gummiformteil aufgebracht werden soll, blankgestrahlt (Sandstrahlen), ein Haftvermittler aufgebracht und die Gummiformteile bei ca. 160°C aufvulkanisiert.After cleaning, the metallic base parts completely galvanized or yellow chromated or zinc phosphated. Then the areas of metallic base material on which the molded rubber part to be applied, blasted (sandblasting), an adhesion promoter applied and the molded rubber parts vulcanized at approx. 160 ° C.

Die Nachteile dieses Verfahrens liegen in der, durch die bei der Vulkanisation hohen Temperaturbehandlung bereits einsetzende Zerstörung der Chromatschichten. Die Teile werden hierdurch bei ihrem späteren Einsatz, insbesondere in den Randbereichen des Übergangs zwischen Metall/Haftvermittler/Gummi wesentlich korrossionsanfälliger. Darüber hinaus trägt die galvanische Behandlung des metallischen Grundkörpers insbesondere bei Erzeugung von Gelbchromatschichten zu einer Belastung der Umwelt mit Schwermetallen bei.The disadvantages of this method are that the high temperature treatment during vulcanization Destruction of the chromate layers already beginning. As a result, the parts are especially in the marginal areas of the transition between Metal / bonding agent / rubber much more susceptible to corrosion. In addition, the galvanic treatment of the metallic base body, especially during production from yellow chromate layers to pollution of the environment with heavy metals.

Ein nachträgliches Lackieren (Pulverlack/Naßlack) der metallischen Oberfläche ist nur mit erheblichem finanziellem und zeitlichem Aufwand der gummierten Teile möglich, da diese abgedeckt werden müssen. Subsequent painting (powder paint / wet paint) metallic surface is only significant financial and time expenditure of the rubberized parts possible because these have to be covered.  

Variante 2Variant 2

DE 27 48 686 beschreibt ein Verfahren, bei dem das metallische Grundmaterial unter unspezifizierten und nicht reproduzierbaren Bedingungen in ein Epoxid-Polyester-Pulvergemisch eingetaucht und dieses anschließend unter unspezifizierten erhöhten Temperaturen thermisch ausgehärtet wird.DE 27 48 686 describes a method in which the metallic base material under unspecified and non-reproducible conditions in one Dipped epoxy-polyester powder mixture and this then under unspecified elevated temperatures is cured thermally.

Durch anschließendes Aufbringen eines hitzeempfindlichen adhäsiven Systems, Inkontaktbringen mit einer elastomeren gummiartigen Verbindung zwischen metallischem Grundmaterial und dem Gummi hergestellt.By subsequently applying a heat sensitive adhesive system, contacting with an elastomer rubbery connection between metallic Base material and the rubber made.

Auf diese Weise hergestellte Verbindungen zwischen metallischem Grundmaterial und Gummi weisen zwar eine relativ hohe Korrosionsbeständigkeit, aber keine ausreichende Widerstandsfähigkeit gegen Schwingungsbelastungen zwischen dem metallischen Grundmaterial und dem Gummi auf und sind für schwingungsbelastete Systeme nur bedingt, d. h. nur mit kürzeren Standzeiten einsetzbar.Connections made in this way between metallic base material and rubber have one relatively high corrosion resistance, but none sufficient resistance to vibration loads between the metallic base material and the rubber on and are only conditional for systems subject to vibration, d. H. just can be used with shorter downtimes.

Unter Vermeidung der den beiden vorstehend beschriebenen Verfahren innewohnenden Nachteile soll die Aufgabe gelöst werden, Metall- und Gummiteile unterschiedlichster Form und Geometrie zu einer hochhaftfesten und korrosionsbeständigen Einheit miteinander zu verbinden.Avoiding the two described above Disadvantages inherent in the process are to be solved, Metal and rubber parts different shape and geometry into one highly adhesive and corrosion-resistant unit connect with each other.

Diese Aufgabe wird durch die im Patentanspruch angegebenen Merkmale gelöst.This object is achieved by the features specified in the patent claim.

Die metallischen Grundkörper werden in einem wäßrigen Entfettungsverfahren behandelt, eisenphosphatiert und anschließend getrocknet.The metallic base bodies are in an aqueous Degreasing process treated, iron phosphated and then dried.

Danach werden sie in einer elektrostatischen Pulver­ beschichtungsanlage mit Epoxi-Polyesterpulver beschichtet und das Pulver in einem Einbrennofen, der durch ein Gebläse auf schwachem Unterdruck gehalten wird, bei erhöhter Temperatur eingebrannt wird. Die aus dem Ofen entnommenen Teile werden nun auf Raumtemperatur abgekühlt und ein Halftvermittler vorzugsweise Zweischicht Gummi-Metall Bindemittel auf den Bereichen des Teils, auf denen sich später das Gummiformteil befinden soll, aufgebracht. Danach wird in einer Form der Rohgummi über die mit Haftvermittler versehenen Teile gebracht und unter erhöhtem Druck und gleichzeitig erhöhter Temperatur aufvulkanisiert.After that, they are in an electrostatic powder coating system coated with epoxy polyester powder and the powder in a baking oven by a blower is kept on weak negative pressure, with increased Temperature is baked. The ones taken out of the oven Parts are now cooled to room temperature and on Semi-intermediary preferably two-layer rubber-metal Binder on the areas of the part on which later the molded rubber part should be applied. Then the raw rubber is placed in a mold over the Adhesion promoter parts brought and under increased pressure and at the same time increased temperature vulcanized.
