Description
Selbstschmierende Erzeugnisse aus synthetischen Werkstoffen, hergestellt in einem VerfahrensschrittSelf-lubricating products made of synthetic materials, manufactured in one process step
Die Entwicklung betrifft selbstschmierende Erzeugnisse aus synthetischen Werkstoffen, die auf der Basis von polymeren, elastomeren und diesen artverwandten Materialien hergestellt sind und eine einstellbare Menge an Schmierstoff beinhalten, der während des Formgebungsprozesses des Erzeugnisses eingebracht und im Laufe der Lebensdauer des Erzeugnisses an die Umgebung abgegeben wird.The development concerns self-lubricating products made of synthetic materials based on polymeric, elastomeric and related materials, which contain an adjustable amount of lubricant that is introduced during the molding process of the product and released into the environment over the life of the product.
Aus dem Stand der Technik ist es bekannt, niedrigere Reibwerte und, in deren zwangsläufiger Folge, eine Verbesserung der Gleitfähigkeit der Oberflächen von Erzeugnissen aus synthetischen Werkstoffen gegenüber den Oberflächen von Erzeugnissen auf ähnlicher Werkstoffbasis oder auch denen einer anderen, so z.B. Gläsern aus silikatischen oder karbooranischen Grundmaterialien, durch die Einbringung und/oder den Auftrag von entsprechenden Materialien und Beschichtungen zu erzielen.It is known from the state of the art to achieve lower friction values and, as a result, an improvement in the sliding properties of the surfaces of products made of synthetic materials compared to the surfaces of products based on a similar material or even those of another material, such as glasses made of silicate or carboanic base materials, by introducing and/or applying appropriate materials and coatings.
Die Einbringung von Materialien zur Verbesserung der Gleitfähigkeit, von sogenannten Gleitmitteln, auch Schmierstoffen in fester, flüssiger oder pastöser Form in das Grundmaterial für Häs Erzeugnis führt an diesem zu einerVerbesserung der'Gleitfähigkeit der Oberfläche, durch Reduzierung des Reibwerts oder auch zu einer permanenten Schmierfähigkeit. Die Anwendbarkeit von Grundmaterial mit verbesserter Gleitfähigkeit für Erzeugnisse sind jedoch dadurch Grenzen gesetzt, so die Gleitmittel zu einer Veränderung der mechan.-physik. Parameter des Erzeugnisses führen und die Gewährleistung der Funktion des Erzeugnisses aufgrund ungenügender Schmierstoffmenge über den geforderten Lebensdauerbereich nicht gegeben ist bzw. die Erzeugnisse für Anwendungen in denen eine kontinuierliche Lebensdauerschmierung mit Schmierstoffen in fester, flüssiger oder pastöser Form gefordert wird nicht geeignet sind. Um eine kontinuierliche Lebensdauerschmierung sicherstellen, muss in vielen Anwendungen ein zusätzlicher Verfahrensschritt dazu verwendet werden, die Lebensdauerschmierstofffüllung einzubringen, wird dabei Menge und Position des Schmierstoffs nicht so gewählt, dass die Schmierung über die nötige Zeit garantiert ist, kann eine Nachschmierung erforderlich werden. Für die Einbringung eines Schmierstoffs, die Schmierung während der Lebensdauer des Erzeugnisses sicherstellend, in Bauteile aus synthetischen Werkstoffen bieten sich sowohl die Technologien des Spritzgießens wie auch die des Extrudierens an.The introduction of materials to improve the sliding properties, so-called lubricants, also lubricants in solid, liquid or pasty form into the base material for a product leads to an improvement in the sliding properties of the surface, by reducing the coefficient of friction or to permanent lubricity. The applicability of base materials with improved sliding properties for products is limited, however, if the lubricants lead to a change in the mechanical and physical parameters of the product and the guarantee of the function of the product is not given due to insufficient lubricant quantity over the required service life range or the products are not suitable for applications in which continuous lifetime lubrication with lubricants in solid, liquid or pasty form is required. In order to ensure continuous lifetime lubrication, in many applications an additional process step must be used to introduce the lifetime lubricant filling. If the amount and position of the lubricant are not selected in such a way that lubrication is guaranteed over the necessary time, relubrication may be necessary. Both injection molding and extrusion technologies are suitable for introducing a lubricant into components made of synthetic materials, ensuring lubrication throughout the product's lifetime.
Die Ausbildung von Hohlräumen durch die Injektion fließender Medien wurde bereits zu Beginn der 70er Jahre im Bereich des Thermoplastschaumgießens untersucht. Dabei wird das fließendeThe formation of cavities by injecting flowing media was already investigated in the early 1970s in the field of thermoplastic foam casting.
Medium aus dem Formhohlraum entfernt oder vom Harzmaterial eingeschlossen. Die Technik der Injektion von Gasen in Kunststoffmaterial, bekannt unter dem Begriff Gasinjektion -im folgenden GIT genannt- zählt zum Bereich der Sonderverfahren des Spritzgießens. Hierbei wird der Formhohlraum eines Spritzgießwerkzeuges zum Teil oder vollständig mit einer Formmasse gefüllt. Danach wird ein Inertgas injiziert, um den noch schmelzeflüssigen Kern der Formmasse auf- oder auszublasen, das Ergebnis ist die Entstehung eines Hohlkörpers. Durch die Injektion von Wasser oder von Alkohol/Wassermischungen nach dem Prinzip der GIT ist es ebenfalls die Erzeugung eines Hohlraumes möglich.Medium is removed from the mold cavity or enclosed by the resin material. The technique of injecting gases into plastic material, known under the term gas injection - hereinafter referred to as GIT - is one of the special injection molding processes. Here, the mold cavity of an injection molding tool is partially or completely filled with a molding compound. An inert gas is then injected to inflate or deflate the still molten core of the molding compound, resulting in the creation of a hollow body. By injecting water or alcohol/water mixtures according to the GIT principle, it is also possible to create a cavity.
