FORMTEILMOLDED PART
Die Erfindung betrifft einen Formteil mit einer zum Wasserschutz dienenden Folie und einem zum Ankleben dienenden Klebemittel .The invention relates to a molded part with a film serving for water protection and an adhesive serving for bonding.
Derartige Teile sind bereits bekannt und bestehen beispielsweise aus einem Polyethylenfilm, der mit einer selbstklebenden Beschichtung als Klebemittel versehen ist. Diese Teile werden zu Feuchtigkeit abdichtenden Abdeckungsmaßnahmen beispielsweise bei Kraftfahrzeugen und insb. bei Kfz-Türen verwendet. Das Teil soll dann verhindern, daß Wasser in den Fahrzeuginnenraum eindringt. Abgesehen von entstehender Faltenbildung beim Ankleben des Teils weist dieser im wesentlichen keinerlei schalldämmende Eigenschaften auf, es sei denn, er ist mit zusätzlichem Absorbermaterial belegt.Such parts are already known and consist, for example, of a polyethylene film that is provided with a self-adhesive coating as an adhesive. These parts are used for covering measures that seal off moisture, for example in motor vehicles and in particular in vehicle doors. The part is then intended to prevent water from penetrating the vehicle interior. Apart from the formation of folds when the part is glued on, it essentially has no sound-insulating properties whatsoever, unless it is covered with additional absorber material.
Die Anwendung offenzelliger Polyurethanschaumschichten zum Zwecke der Schalldämmung verlangt dagegen die Einhüllung der Schaumschicht in eine wasserdichte Folie. Auch hier sind Faltenbildungen beim Ankleben und Montieren kaum vermeidbar.The use of open-cell polyurethane foam layers for sound insulation purposes, however, requires the foam layer to be wrapped in a waterproof film. Here too, wrinkles can hardly be avoided when gluing and installing.
Der Erfindung liegt die Aufgabe zugrunde, ein derartiges Formteil hinsichtlich seiner Funktion, darunter auch schall-The invention is based on the object of improving such a molded part with regard to its function, including sound

dämmenden bzw. schalldämpfenden Aufgabe, bei einfacher Herstellung und Montierbarkeit zu verbessern.insulating or sound-absorbing function, while being easy to manufacture and assemble.
Die Erfindung ist im Anspruch 1 gekennzeichnet und in Unteransprüchen sind besondere Ausbildungen derselben beansprucht. Die Zeichnung demonstriert bevorzugte Ausführungsformen und ist daher gleichfalls Offenbarungsträger für die Erfindung.The invention is characterized in claim 1 and special embodiments thereof are claimed in subclaims. The drawing demonstrates preferred embodiments and is therefore also a disclosure medium for the invention.
Gemäß der Erfindung ist die Folie als Schaumfolie ausgebildet und besteht insb. aus einem Polyolefinschaum, darunter insb. Polyethylenschaum. An der vom Klebemittel abgewandten Seite ist die Schaumfolie mit einer Vliesschicht insb. durch Kaschieren verbunden. Die Vliesschicht sollte ein Flächengewicht zwischen 400 und 2000 g/m2, insb. zwischen 600 und 800 g/m2 aufweisen. Es empfiehlt sich, beide Teile zuerst zu laminieren und dann das Gebilde vakuumzuverformen.According to the invention, the film is designed as a foam film and consists in particular of a polyolefin foam, including in particular polyethylene foam. On the side facing away from the adhesive, the foam film is connected to a fleece layer, in particular by lamination. The fleece layer should have a surface weight of between 400 and 2000 g/m 2 , in particular between 600 and 800 g/m 2 . It is recommended to laminate both parts first and then vacuum-form the structure.
Es empfiehlt sich als Klebemittel eine sogen. „Kleberraupe" zu verwenden. Dabei handelt es sich um Klebstoff, der im Querschnitt wulstförmig, beispielsweise oval oder rund im Querschnitt, ausgebildet ist und als Band im Randbereich der Schaumfolie um diese umlaufend mit der Schaumfolie verbunden ist. Hierdurch wird das Eindringen von Wasser oder anderer Flüssigkeit von innerhalb des Klebebereichs, also Türinnenraum, in den Fahrgastinnenraum verhindert.It is recommended to use a so-called "adhesive bead" as an adhesive. This is an adhesive that has a bead-shaped cross-section, for example oval or round in cross-section, and is connected to the foam film as a band in the edge area around it. This prevents water or other liquids from within the adhesive area, i.e. the inside of the door, from penetrating the passenger compartment.
Die Schichtdicke der Schaumfolie sollte zwischen 1 und 5 mm betragen.The layer thickness of the foam film should be between 1 and 5 mm.
Für die Vliesschicht empfiehlt sich die Verwendung eines Baumwollfaservlieses, das ggf. auch mit thermoplastischem Kunststoff vermischt sein kann, um als Mischfasersystem zuFor the fleece layer, it is recommended to use a cotton fibre fleece, which can also be mixed with thermoplastic material if necessary, in order to create a mixed fibre system.
wirken. Die thermoplastischen Faseranteile begünstigen das Verbinden der Vliesschicht mit der Schaumfolie.The thermoplastic fiber components promote the bonding of the fleece layer with the foam film.
Darüber hinaus kann aber auch eine haftungsverbessernde Bindeschicht zwischen beiden Schichten eingebracht sein. Hierzu dient insb. eine als Film ausgebildete dünne Folie oder ein Vlies eines handelsüblichen Schmelzklebers (Hotmelt).In addition, an adhesion-improving bonding layer can also be introduced between the two layers. This can be done using a thin film or a fleece made of a commercially available hot melt adhesive.
Zur Erhöhung der Eigensteifigkeit oder Verbesserung der akustischen Eigenschaften des Systems kann die dem Fahrzeuginnenraum zugewandte Seite des Baumwollfaservlieses mit einem Vlies oder einer Folie, das/die ebenfalls mittels Schmelzkleber aufgebracht wird, ausgerüstet werden. Das Flächengewicht des Vlieses sollte zwischen 10 und 15 g/m2 betragen. Derartige Vliese können auch oleophob oder hydrophob ausgerüstet sein. Besonders geeignet sind hierfür Cellulosefaservliese oder Vliese aus Polyester oder Polyolefinen.Zur Verbesserung der Absoptionsverteilung werden bevorzugt Filme aus einer dünnen Polyurethan- oder Polyethylenschicht mit einer Filmdicke zwischen 15 und 30 &mgr;&khgr;&agr; verwendet.To increase the inherent rigidity or improve the acoustic properties of the system, the side of the cotton fiber fleece facing the vehicle interior can be equipped with a fleece or a film, which is also applied using a hot melt adhesive. The basis weight of the fleece should be between 10 and 15 g/m 2 . Such fleeces can also be made oleophobic or hydrophobic. Cellulose fiber fleeces or fleeces made of polyester or polyolefins are particularly suitable for this. To improve the absorption distribution, films made of a thin polyurethane or polyethylene layer with a film thickness of between 15 and 30 μΩα are preferably used.
Die Erfindung bildet ein genügend eigensteifes Formteil, das den Kontouren desjenigen Teiles bereits bei der Herstellung entsprechend angepaßt sein sollte, an das es durch bloßes Andrücken dort angeklebt wird, um seine Funktion als Wasserschutzteil und zusätzlich als „Schallabsorber" ohne verhältnismäßig große Gesamtdicke zu erfüllen. Die Gesamtdicke sollte weniger als 10 mm betragen.The invention forms a sufficiently inherently rigid molded part that should be adapted to the contours of the part to which it is glued by simply pressing it on during manufacture in order to fulfill its function as a water protection part and additionally as a "sound absorber" without a relatively large overall thickness. The overall thickness should be less than 10 mm.
Für die Schaumfolie empfiehlt sich ein Vinylpolymer, insb. Polyethylen, aber auch Polypropylen.A vinyl polymer, especially polyethylene, but also polypropylene, is recommended for the foam film.
Für die Kleberraupe empfiehlt sich ein selbstklebender Heißschmelzkleber auf Butylkautschukbasis.For the adhesive bead, a self-adhesive hot melt adhesive based on butyl rubber is recommended.
Für den Schmelzkleber, der als Haftungsvermittler zwischen Wollfaservlies und Schaumfolie bzw. Vliesschicht und Baumwollfaservlies verwendet wird, empfiehlt sich EVA, Polyester oder auch ein nachvernetzender Schmelzkleber, da hierdurch ein Auflösen der Verbindung während des endgültigen Vakuumformens, das insb. auch unter Erwärmen erfolgt, vermieden wird.For the hot melt adhesive used as an adhesion promoter between wool fiber fleece and foam film or fleece layer and cotton fiber fleece, EVA, polyester or a post-curing hot melt adhesive is recommended, as this prevents the bond from dissolving during the final vacuum forming, which is particularly carried out under heating.
Die Erfindung ist anhand der Zeichnung im folgenden näher erläutert. Dabei zeigen:The invention is explained in more detail below with reference to the drawing, in which:

Teil einer Kfz-Türe.Part of a car door.
Gemäß Figur 1 weist das Formteil eine Vliesschicht 1, z.B. Baumwollfaservlies, und eine Schaumfolie 3 auf, die durch eine Bindeschicht 2 miteinander verbunden sind. Das aus diesen drei Schichten bestehende Formteil stellt eine genügende eigensteife Mehrschichteneinheit dar, die vorgefertigt und dem Kfz-Hersteller zugeliefert wird, um an Ort und Stelle am betreffenden Bauteil appliziert zu werden, ohne zusätzliche Bearbeitung zu verlangen. Um die Applikation einerseits und die Abdichtung andererseits zu erleichtern, ist die Schaumfolie 3 im Bereich des Umfangrandes 3a derselben mit einer Kleberraupe 4 versehen, welche um den Umfang der Schaumfolie umläuft und nicht nur das Befestigen des Formteil ermöglicht,According to Figure 1, the molded part has a fleece layer 1, e.g. cotton fiber fleece, and a foam film 3, which are connected to one another by a binding layer 2. The molded part consisting of these three layers represents a sufficiently rigid multi-layer unit that is prefabricated and delivered to the vehicle manufacturer in order to be applied on site to the relevant component without requiring additional processing. In order to facilitate the application on the one hand and the sealing on the other, the foam film 3 is provided with an adhesive bead 4 in the area of the peripheral edge 3a of the same, which runs around the circumference of the foam film and not only enables the molded part to be attached,
sondern auch das Eindringen von Wasser oder anderer Feuchtigkeit vom Raum innerhalb des Klebebereichs, also Türinnenraum, in den Fahrgastinnenraum verhindert.but also prevents the penetration of water or other moisture from the space within the adhesive area, i.e. the inside of the door, into the passenger compartment.
Bei diesem bevorzugten Ausführungsbeispiel besteht die Vliesschicht 1 aus einem Mischfasersystem mit vorwiegend Baumwollfasern sowie mit zusätzlich thermoplastischen Kunststofffasern. Dieses Mischfasersystem kann zusätzlich oleofob oder hydrofob ausgerüstet sein bis zu einem Flächengewicht von etwa 600 und 800 g/m2. Es wurde festgestellt, daß eine solche Vliesschicht 1 das Vielfache der akustischen Absorptionsfähigkeit eines gleichstarken offenzelligen Polyurethanschaumes aufweist. Optional ist die Vliessschicht 1 an einer Seite mit einem hydrophob ausgerüsteten Cellulosefaservlies als Außenhaut la überzogen, dessen Flächengewicht zwischen 10 und 15 g/m2 besteht und das gleichfalls hydrophob ausgerüstet ist. Die Außenhaut la kann auch als Polyurethanhaut oder PoIyethylenfilm ausgebildet sein.In this preferred embodiment, the fleece layer 1 consists of a mixed fiber system with predominantly cotton fibers and additional thermoplastic fibers. This mixed fiber system can also be made oleophobic or hydrophobic up to a basis weight of about 600 and 800 g/m 2 . It has been found that such a fleece layer 1 has many times the acoustic absorption capacity of an equally strong open-cell polyurethane foam. Optionally, the fleece layer 1 is covered on one side with a hydrophobic cellulose fiber fleece as an outer skin 1a, the basis weight of which is between 10 and 15 g/m 2 and which is also made hydrophobic. The outer skin 1a can also be designed as a polyurethane skin or polyethylene film.
Für die Bindeschicht 2 kann als Haftvermittler auch ein Schmelzkleber in Form einer Folie, insb. eines dünnen Film, oder aber in Form eines Gitters oder von Pulver verwendet werden.For the binding layer 2, a hot melt adhesive in the form of a foil, in particular a thin film, or in the form of a grid or powder can also be used as an adhesion promoter.
Die Verbindung zwischen Vliesschicht 1 und Schaumfolie 3 kann auch durch Wärmeanwendung, beispielsweise unter Zuhilfenahme von IR-Strahlung erfolgen, wodurch die Schaumfolie aktiviert und die Kaschierung begünstigt wird.The connection between fleece layer 1 and foam film 3 can also be made by applying heat, for example with the aid of IR radiation, which activates the foam film and promotes lamination.
Für die Schaumfolie 3 ist eine Folie aus Polyethylenschaum mit einem Raumgewicht zwischen 30 und 250 kg/m3, insb. vonFor the foam foil 3, a foil made of polyethylene foam with a density between 30 and 250 kg/m 3 , in particular

which has a thickness of 5 mm.
Die Kleberraupe 4 besteht aus einem selbstklebenden Heißschmelzkleber auf Butylkautschukbasis.The adhesive bead 4 consists of a self-adhesive hot melt adhesive based on butyl rubber.
Gemäß Figur 2 ist der als Türabdicht- und -dämpfungsfölie 10 dienende Formteil mittels der Kleberaupe 4 an den Innenblechteil 7a des Türblechs 7 angeklebt mit der als Absorber wirksamen Absorberseite A in Richtung zum Fahrgastinnenraum 5. Dabei ist die Türe - und daher auch der Formteil - zum Fahrgastinnenraum 5 hin mit einer Türinnenverkleidung 8 abgedeckt. Der Formteil dichtet diesen Fahrgastinnenraum 5 und die Innenverkleidung 8 gegen Wasser ab, das z.B. durch den Spalt zwischen dem Fallfenster 6 bzw. dem Fensterglas und der Dichtleiste 11 in den sogenannten „Naßbereich" 9 eindringen kann.According to Figure 2, the molded part serving as a door sealing and damping film 10 is glued to the inner sheet metal part 7a of the door sheet metal 7 by means of the adhesive bead 4 with the absorber side A acting as an absorber in the direction of the passenger compartment 5. The door - and therefore also the molded part - is covered with an inner door panel 8 towards the passenger compartment 5. The molded part seals this passenger compartment 5 and the inner panel 8 against water, which can penetrate, for example, through the gap between the drop window 6 or the window glass and the sealing strip 11 into the so-called "wet area" 9.
Das erfindungsgemäße Formteil ist bei Anwendung kostengünstiger Ausgangsmaterialien einfach herstellbar, zeichnet sich durch eine gute Wasserschutzfunktion aus und wirkt gleichzeitig akustisch stark absorbierend. Insb. die Sandwichfolie ist biaxial vorstreckbar, so daß eine gute Möglichkeit der Vorformung in die endgültige dreidimensionale Form besteht.The molded part according to the invention is easy to manufacture using inexpensive starting materials, is characterized by a good water protection function and at the same time has a strong acoustic absorption effect. In particular, the sandwich film can be pre-stretched biaxially, so that there is a good possibility of pre-forming it into the final three-dimensional shape.
