Description

K u n s t s t o f f p l a t t e K u n s t s t o f f p l a t t e
Die Erfindung betrifft eine Kunststoffplatte aus der durch Thermoformen, insbesondere Tiefziehen ein Kunststoffartikel herstellbar ist. Weiters betrifft die Erfindung einen Kunststoffartikel, der durch Thermoformen oder Tiefziehen aus einer solchen Kunststoffplatte herstellbar ist. Darüber hinaus betrifft die Erfindung Verfahren zum Herstellen solcher Kunststoffplatten bzw. Kunststoffartikel.The invention relates to a plastic plate from which a plastic article can be produced by thermoforming, in particular deep drawing. The invention further relates to a plastic article which can be produced from such a plastic plate by thermoforming or deep drawing. In addition, the invention relates to methods for producing such plastic sheets or plastic articles.
Es ist bereits bekannt, Polyurethanschaum als Verstärkung bzw. Isolation an thermo- geformten (d. h. unter Wärmeeinwirkung geformten), aus Platten hergestellten Teilen zu verwenden, beispielsweise für Sanitärteile (Dusch-Badewannen, Dusch- BadewannenPaneele), Karosserieteile oder ähnliches. Die Aufgabe des PUR- Schaumes ist einmal eine mechanische Verstärkung durch Erhöhen des E-Moduls, was eine statische Verbesserung bringt. Weiters kann ein solcher PUR-Schaum zur Thermo-Isolation verwendet werden, einerseits zur Kühlraum-Isolation, andererseits als thermischer Schutz gegen Überhitzung.It is already known to use polyurethane foam as reinforcement or insulation on thermoformed (ie shaped under the action of heat) parts made from plates, for example for sanitary parts (shower trays, shower tray panels), body parts or the like. The purpose of the PUR foam is mechanical reinforcement by increasing the modulus of elasticity, which brings about a static improvement. Such a PUR foam can also be used for thermal insulation, on the one hand for cold room insulation, and on the other hand as thermal protection against overheating.
Es hat sich in der Praxis gezeigt, daß sich die aufgebrachte Polyurethanschaumschichte (Polyol und Izocyanat) immer wieder von der Plattenrückseite der Grundplatte (d. h. von der im Gebrauch nicht sichtbaren Seite) löst.It has been shown in practice that the applied polyurethane foam layer (polyol and izocyanate) keeps detaching from the back of the base plate (i.e. from the side that is not visible during use).
Um dies zu vermeiden, sieht die Erfindung eine Kunststoffplatte vor, die durch eine ein- oder mehrschichtige Grundplatte gekennzeichnet ist, auf der eine gesonderte Haftverbesserungsschicht aus einem thermoplastischen Polymer zur Verbesserung der Haftung eines darauf aufzubringenden geschäumten Polymers angeordnet ist. Das thermoplastische Polymer (Kunststoff) besteht aus einem gesonderten (unterschiedlichen) Material wie die Rückseite der Grundplatte und kann daher so ausgewählt werden, daß die Haftfähigkeit für das verwendete geschäumte Polymer, insbesondere PUR-Schaum (Polyurethanschaum), verbessert wird.To avoid this, the invention provides a plastic plate, which is characterized by a single- or multi-layer base plate, on which a separate adhesion-enhancing layer made of a thermoplastic polymer is arranged to improve the adhesion of a foamed polymer to be applied thereon. The thermoplastic polymer (plastic) consists of a separate (different) material like the back of the base plate and can therefore be selected so that the adhesiveness for the foamed polymer used, in particular PUR foam (polyurethane foam), is improved.
Zur Verbesserung der Haftfähigkeit von PUR-Schaum eignen sich Haftverbesserungsschichten, die vorteilhafterweise folgende Eigenschaften aufweisen: ♦ Die Haftverbesserungsschicht ist ein durch Zugabe von hydrophilen Stoffen, vorzugsweise Aminderivaten oder Polyethylenglykolester modifiertes ABS.Adhesion improvement layers are suitable for improving the adhesion of PUR foam, which advantageously have the following properties: ♦ The adhesion improvement layer is an ABS modified by adding hydrophilic substances, preferably amine derivatives or polyethylene glycol esters.
und/oderand or
♦ Die Haftverbesserungsschicht ist ein ABS (Acrylnitril-Butadien-Styrol) mit einem Butadiengehalt von über 20 Gew.-%, vorzugsweise mit einem Butadiengehalt von ca. 25 Gew.-%.♦ The adhesion improvement layer is an ABS (acrylonitrile-butadiene-styrene) with a butadiene content of over 20% by weight, preferably with a butadiene content of approx. 25% by weight.
und/oderand or
♦ Die Haftverbesserungsschicht ist ein ABS mit Butadienpartikeln in der Matrix, die größer als 0,005 mm sind, vorzugsweise um 0,008 mm groß sind.♦ The adhesion improvement layer is an ABS with butadiene particles in the matrix which are larger than 0.005 mm, preferably around 0.008 mm in size.
Die Haftverbesserungsschicht kann grundsätzlich auf verschiedene Arten an der Grundplatte angebracht werden. Eine besonders innige Verbindung und eine einfache Herstellbarkeit ist durch die bevorzugte Koextrusion von Grundplatte und Haftverbesserungsschicht gewährleistet. Die Schichtdicke der Haftverbesserungsschicht liegt günstigerweise zwischen 2 % und 10 % der Dicke der gesamten Kunststoffplatte. Sie kann also relativ dünn ausfallen.The adhesion improvement layer can basically be applied to the base plate in different ways. A particularly intimate connection and ease of manufacture is ensured by the preferred coextrusion of the base plate and the adhesion-promoting layer. The layer thickness of the adhesion-improving layer is advantageously between 2% and 10% of the thickness of the entire plastic plate. So it can be relatively thin.
Mit der erfindungsgemäßen Kunststoffplatte läßt sich durch Thermoformen, insbesondere Tiefziehen ein Kunststoffartikel, wie beispielsweise eine Badewanne, herstellen. Erfindungsgemäß wird dann auf diesen Kunststoffartikel auf die Haftverbesserungsschicht ein geschäumter Polymer, insbesondereWith the plastic plate according to the invention, a plastic article, such as a bathtub, can be produced by thermoforming, in particular deep drawing. According to the invention, a foamed polymer, in particular, is then applied to this plastic article on the adhesion improvement layer
Polyurethanschaum aufgebracht und zwar entweder drucklos durch Aufspritzen oder Aufgießen oder unter Druck in einer geschlossenen Form.Polyurethane foam applied, either without pressure by spraying or pouring, or under pressure in a closed mold.
Weitere Vorteile und Einzelheiten der Erfindung werden anhand eines Ausführungsbeispieles näher erläutert. Die Fig. 1 zeigt die Koextrusion der Grundplatte mit einer Haftverbesserungsschicht eines Ausführungsbeispieles einer erfindungsgemäßen Kunststoffplatte.Further advantages and details of the invention are explained in more detail using an exemplary embodiment. 1 shows the coextrusion of the base plate with an adhesion-improving layer of an exemplary embodiment of a plastic plate according to the invention.
Die Fig. 2 zeigt eine aus dieser Kunststoffplatte hergestellte Badewanne in einem schematischen Längsschnitt.Fig. 2 shows a bathtub made of this plastic sheet in a schematic longitudinal section.
Bei dem in Fig. 1 dargestellten Ausführungsbeispiel wird aus einer Extrusionsdüse 1 eine Grundplatte 2 aus (Standard) ABS mit einer Haftverbesserungsschicht 3 koextrudiert. Die Haftverbesserungsschicht kann aus einem speziellen ABS bestehen, wie dies weiter oben ausgeführt worden ist.In the exemplary embodiment shown in FIG. 1, a base plate 2 made of (standard) ABS is co-extruded from an extrusion die 1 with an adhesion-improving layer 3. The adhesion-improving layer can consist of a special ABS, as was explained above.
Aus dieser zunächst ebenen Kunststoffplatte 2, 3 kann durch Thermoformen, insbesondere Tiefziehen ein räumlich geformter Kunststoffartikel hergestellt werden, beispielsweise eine Badewanne, wie sie in Fig. 2 gezeigt ist. Bei der in Fig. 2 dargestellten Badewanne ist auf der im Betrieb nicht sichtbaren Rückseite eine Polyurethanschicht 4 aufgetragen, die fest an der Haftverbesserungsschicht 3 haftet und damit eine innige Verbindung zur Grundplatte 2 sichergestellt ist.A spatially shaped plastic article, for example a bath tub, as shown in FIG. 2, can be produced from this initially flat plastic plate 2, 3 by thermoforming, in particular deep drawing. In the bathtub shown in FIG. 2, a polyurethane layer 4 is applied to the rear side, which is not visible during operation, which adheres firmly to the adhesion-improving layer 3 and thus ensures an intimate connection to the base plate 2.
Die Erfindung ist selbstverständlich nicht auf die dargestellten Ausführungsbeispiele beschränkt, beispielsweise sind auch andere Schaumarten als Polyurethanschaum möglich (z. B. Acrylatschäume). Statt dem Koextrudieren von Grundplatte und Haftverbesserungsschicht ist auch ein Auflaminieren oder eine andere Verbindungsart durchaus denkbar und möglich. The invention is of course not limited to the exemplary embodiments shown, for example other types of foam than polyurethane foam are also possible (e.g. acrylate foams). Instead of co-extruding the base plate and the adhesion improvement layer, lamination or another type of connection is also conceivable and possible.
