Während es möglich sein kann, eine fluiddichte Verbindung nach Art einer mechanischen Verzahnung zu erzielen, wo der Bestandteil aus einem Material wie Messing besteht, ist der Gebrauch dieses Materials nicht immer akzeptabel; z. B. wurde in dem Fall eines Artikels, welcher in einer Technik mit verlorenem Kern hergestellt wurde, festgestellt, daß das leicht schmelz bare Formkernausschmelzmaterial dazu neigt, an dem Be standteil unerwünschterweise zu haften. Das kann besondere Probleme bringen, wo der Bestandteil die Formation eines Schraubengewindes aufweist, da es nicht einfach ist, von dem Schraubengewinde irgendwelches zurückgebliebenes Kernmaterial zu entfernen.A problem that arises when making a composite art fabric product, consists in obtaining a required joint detention center between the main or Basic body and a structural component of the product or article. This can be a particular difficulty there be where it is necessary to establish a fluid-tight connection between to maintain the main body and components. While it may be possible to establish a fluid-tight connection according to Art to achieve a mechanical toothing where the component is made of a material like brass, is use this material is not always acceptable; e.g. B. was in the Case of an article which is in a technique with lost Core was found to melt easily bare mold lost core tends to adhere to the loading to adhere part undesirably. That can be special Bring problems where the component is the formation of a Has screw thread, since it is not easy from which Screw thread any remaining core material to remove.
In Übereinstimmung mit einem ihrer Aspekte stellt die vor liegende Erfindung einen Verbundkunststoffartikel bereit, welche einen Hauptkörper aus Kunststoffmaterial aufweist, welcher damit integriert und daran haftend einen Strukturbe standteil hat, wobei der Strukturbestandteil angrenzend an den Hauptkörper aus Kunststoffmaterial wenigstens einen Ober flächenbereich aus Aluminium oder dergleichen Material auf weist, welches eloxiert bzw. anodisiert worden ist.In accordance with one of its aspects, it presents lying invention a composite plastic article ready which has a main body made of plastic material, which integrates with it and adheres to it has part, with the structural component adjacent to the main body made of plastic material at least one upper surface area made of aluminum or similar material indicates which anodized or anodized.
Die Bezugnahme auf Aluminium oder dergleichen Material schließt Aluminiumlegierungen ein und meint damit ein metal lenes Material einer Art, welches eloxiert bzw. anodisiert werden kann.The reference to aluminum or the like material includes aluminum alloys and means a metal lenes material of a kind that anodizes or anodizes can be.
Vorzugsweise ist die eloxierte bzw. anodisierte Schicht durch Eloxieren bzw. Anodisieren mittels Schwefelsäure gebildet.The anodized or anodized layer is preferably through Anodizing or anodizing using sulfuric acid.
Vorzugsweise sollte die eloxierte bzw. anodisierte Schicht eine Dicke von nicht mehr als 20 µm und insbesondere von nicht mehr als 12 µm haben.The anodized or anodized layer should preferably be used a thickness of not more than 20 µm and in particular of have no more than 12 µm.
Die vorliegende Erfindung faßt ins Auge, daß vorzugsweise die eloxierte bzw. anodisierte Schicht eine solche ist, welche durch eine Eloxier- bzw. Anodisierverfahren gebildet ist, welches die Anwendung einer elektrischen Potentialdifferenz zwischen 4 und 14 Volt, vorzugsweise zwischen 8 und 10 Volt, einer Temperatur im Bereich von 15 bis 25°C und insbesondere in dem Bereich von 18 bis 22°C und einer Eloxier- bzw. Ano disierzeit von wenigstens 10 Minuten, und insbesondere von wenigstens 20 Minuten einschließt.The present invention contemplates that preferably the anodized or anodized layer is one which is formed by an anodizing or anodizing process, which is the application of an electrical potential difference between 4 and 14 volts, preferably between 8 and 10 volts, a temperature in the range of 15 to 25 ° C and in particular in the range from 18 to 22 ° C and an anodizing or ano time of at least 10 minutes, and in particular of includes at least 20 minutes.
Das Kunststoffmaterial des Verbundartikels kann ein Hauptkör per aus einer phenolischen Formmasse sein, z. B. einem in Wärme aushärtenden glasverstärkten Phenolharz.The plastic material of the composite article can be a main body by from a phenolic molding composition, e.g. B. one in Thermosetting glass reinforced phenolic resin.
Vorzugsweise ist der Strukturbestandteil aus Aluminium oder dergleichen Material ein solcher, welcher in einem Schwefel säure-Eloxier- bzw. -Anodisierbad behandelt worden ist und eine eloxierte bzw. anodisierte Schicht mit einer Dicke von nicht mehr als 8 µm hat. The structural component is preferably made of aluminum or the same material is one which is in a sulfur acid anodizing or anodizing bath has been treated and an anodized or anodized layer with a thickness of has no more than 8 µm.
Eine Ausführungsform der vorliegenden Erfindung wird jetzt nur beispielsweise unter Bezugnahme auf ein formgepreßtes Kunststoffthermostatgehäuse einer Art beschrieben, welches einen Körper aus in Wärme aushärtenden glasverstärkten Harz aufweist, welcher damit integriert eine Vielzahl von Schraubgewindeeinsätzen hat, welche das Anbringen des Arti kels an einem Stützgerüst erleichtern.An embodiment of the present invention will now for example only with reference to a compression-molded one Plastic thermostat housing of a type described, which a body made of thermosetting glass reinforced resin which integrates a variety of Has screw thread inserts, which the attachment of the Arti lighten kels on a scaffolding.
Die Schraubgewindeeinsätze sind aus einer Aluminiumlegierung, wie einer Legierung in Übereinstimmung mit BS 1474 (1987) 6082, welche einem Schwefelsäureeloxier- bzw. -anodisierver fahren unterworfen worden ist.The screw thread inserts are made of an aluminum alloy, like an alloy in accordance with BS 1474 (1987) 6082, which a sulfuric acid anodizing or anodizing driving has been subjected.
In dem Eloxier- bzw. Anodisierverfahren werden die Aluminium einsätze für bis zu 30 Minuten in einem Eloxier- bzw. Anodi sierbad mit einer 18%igen Schwefelsäure bei einer Temperatur von 20 +/- 2°C und mit einer Spannungspotentialdifferenz von 9 +/- 1 Volt angeordnet. Der Schraubengewindebereich der Oberfläche der Einsätze kann während des Eloxierens bzw. Anodisierens abgedeckt werden, so daß nur andere Oberflächen des Einsatzes, wie solche Oberflächen zum Verbinden mit einem in Wärme aushärtenden Hauptkörpermaterial vollständig dem Eloxier- bzw. Anodisierverfahren ausgesetzt werden.In the anodizing or anodizing process, the aluminum Inserts for up to 30 minutes in an anodizing or anodizing sierbad with an 18% sulfuric acid at one temperature of 20 +/- 2 ° C and with a voltage potential difference of 9 +/- 1 volt arranged. The screw thread area of the The surface of the inserts can be removed during anodizing or Anodizing are covered so that only other surfaces of use, such as surfaces to connect to a in thermoset main body material completely the Anodizing or anodizing processes are exposed.
Nachher werden die Einsätze in einer Form in einer geforder ten Beziehung relativ zu einem vorgeformten Kern aus leicht schmelzbarem Ausschmelzmaterial angeordnet. Heißes Kunst stoffmaterial wird dann in die Form eingespritzt und chemisch aushärten gelassen, um einen starren Gehäusekörper zur Verfü gung zu stellen, welcher- teilweise an den eloxierten bzw. anodisierten Oberflächen der Einsätze anhaftet und dies um gibt. Afterwards, the stakes are called in one form in one th relationship relative to a preformed core from light fusible melting material arranged. Hot art Material is then injected into the mold and chemically hardened to provide a rigid body supply, which - partly on the anodized or anodized surfaces of the inserts adhered to and around gives.
Die so gebildete Anordnung wird dann ausreichend erwärmt um ein Ausschmelzen des leicht schmelzbaren Kerngliedmaterials zu verursachen.The arrangement thus formed is then sufficiently heated melting of the easily fusible core member material to cause.
