Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen von akustischen Bauplatten nach dem Oberbegriff des Anspruchs 1, sowie eine akustische Bauplatte nach dem Oberbegriff des Anspruchs 10.The invention relates to a method for producing acoustic structural panels according to the preamble of
Eine derartige schallschluckende Bauplatte dient in der Hauptsache zur Verkleidung von Innenraumwänden, insbesondere als Wand- oder Deckenpaneele. Sie ist auch als Türpaneel oder Türe verwendbar.Such sound-absorbing building board is used mainly for the lining of interior walls, in particular as wall or ceiling panels. It can also be used as a door panel or door.
Schallschluckende Bauplatten werden dort verwendet, wo die akustischen Verhältnisse eines Raums beeinflusst werden sollen. Am weitesten verbreitet ist die Verwendung als Deckenplatte, obwohl auch schallschluckende Wandplatten eingebaut werden. Für schallschluckende Bauplatten werden poröse Plattenkörper verwendet, z.B. Holzspanplatten oder Mineralfaserplatten. Diese Platten sind selber schallschluckend und können ohne zusätzliche schallschluckende Einrichtungen zur Herstellung von akustischen Wand- oder Deckenpaneelen verwendet werden. Die Platten sind selbsttragend und können aufgrund ihrer Tragfähigkeit mit verhältnismäßig großen Abmessungen hergestellt werden. Es ist auch bekannt, solche an sich schallschluckenden Bauplatten an ihrer Sichtseite mit einer mikroporösen Folie zu beschichten. Die mikroporöse Folie hat in der Hauptsache die Aufgabe, eine andere Oberflächenstruktur ohne gleichzeitige Beeinträchtigung der Schallschluckeigenschaften zu erzeugen, da schallschluckende Platten ansonsten ästhetischen Anforderungen nicht immer entsprechen können.Sound-absorbing building panels are used where the acoustic conditions of a room are to be influenced. The most widely used is as a ceiling tile, although sound-absorbing wall panels are installed. For sound-absorbing construction panels, porous panels are used, eg particle board or mineral fiber boards. These panels are themselves sound-absorbing and can be used without additional sound-absorbing equipment for the production of acoustic wall or ceiling panels. The panels are self-supporting and can be manufactured with relatively large dimensions due to their load capacity. It is also known to coat such sound-absorbing structural panels on their visible side with a microporous film. The main purpose of the microporous film is to provide a different surface structure without concomitant deterioration the sound-absorbing properties, since sound-absorbing panels can not always meet aesthetic requirements.
Eine Akustikplatte in Sandwichbauweise ist aus der
Nachteilig ist dabei, dass durch den Kaschierprozess, bei dem die Deckschicht auf die Tragstruktur aufgebracht wird, dennoch der Klebstoff die Porosität sowohl der Trägerplatte als auch der Deckschicht vermindert.A disadvantage is that by the lamination process, in which the cover layer is applied to the support structure, yet the adhesive reduces the porosity of both the support plate and the cover layer.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung einer Bauplatte sowie eine akustische Bauplatte zu schaffen, bei der der Herstellprozess vereinfacht ist und die schallschluckenden Eigenschaften der Bauplatte verbessert sind.The invention is therefore based on the object to provide a method for producing a building board and an acoustic building board, in which the manufacturing process is simplified and the sound-absorbing properties of the building board are improved.
Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1 bzw. 10.To solve this problem serve the features of
Die Erfindung sieht in vorteilhafter Weise vor, dass die Deckschicht mit Hilfe von Laserlicht nach dem Kaschieren mit einer Mikroperforation versehen wird. Die mit Laserlicht erzeugte Mikroperforation schafft Mikroporen, die die Deckschicht, eine Klebeschicht zwischen der Deckschicht und der Tragstruktur und eventuell zwischen Deckschicht und Tragstruktur angeordnete Zwischenschichten durchdringen. Ein weiterer Vorteil besteht darin, dass die Mikroperforation erst nach dem Kaschieren erzeugt wird und in besonders vorteilhafter Weise während des Kaschierens beim Aufbringen der Deckschicht erfolgen kann.The invention advantageously provides that the cover layer is provided with a microperforation by means of laser light after lamination. The micro-perforation produced by laser light creates micropores which penetrate the cover layer, an adhesive layer between the cover layer and the support structure and intermediate layers possibly arranged between cover layer and support structure. Another advantage is that the microperforation is produced only after lamination and can be done in a particularly advantageous manner during lamination when applying the cover layer.
Als Tragstruktur kann eine Holzspanplatte oder Holzfaserplatte mit einem Schüttgewicht von 300 bis 500 kg/m3 verwendet werden, wobei ein Schüttgewicht von 400 kg/m3 bevorzugt wird. Alle ganzzahligen Zwischenwerte zwischen 300 bis 500 kg/m3 sollen als offenbart gelten.As a support structure, a chipboard or wood fiber board can be used with a bulk density of 300 to 500 kg / m 3 , with a bulk density of 400 kg / m 3 is preferred. All integer intermediate values between 300 and 500 kg / m 3 should be considered disclosed.
Die Mikroperforation kann computergesteuert mit dem Laserlicht erzeugt werden, wobei eine gleichmäßige oder ungleichmäßige Rasterstruktur erzeugt werden kann. Auch die Querschnittsform der Mikroporen kann programmiert verändert werden. Die Mikroporen können beispielsweise eine schlitzförmige, dreieckförmige und/oder quadratische und/oder wabenförmige Mikroporenstruktur aufweisen.The microperforation can be generated computer-controlled with the laser light, producing a uniform or non-uniform grid structure can. The cross-sectional shape of the micropores can also be programmed. The micropores may, for example, have a slot-shaped, triangular and / or square and / or honeycomb microporous structure.
Es besteht auch die Möglichkeit, die Mikroporen unter einem Schrägwinkel zur Oberfläche der Deckschicht einzubringen. Dies hat den Vorteil, dass die Sichtbarkeit der Mikroporen verringert wird.It is also possible to introduce the micropores at an oblique angle to the surface of the cover layer. This has the advantage that the visibility of the micropores is reduced.
Die Mikroporen haben einen Durchmesser zwischen 200 und 600 µm, wobei jeder ganzzahlige Zwischenwert als offenbart gelten soll. Vorzugsweise ist ein Durchmesser der Mikroporen von ca. 400 µm vorgesehen. Die Porenfläche der Mikroperforation soll mehr als 10 % der Deckschichtfläche betragen und vorzugsweise im Bereich zwischen 12 und 15 % liegen.The micropores have a diameter between 200 and 600 microns, each integer intermediate value should be considered disclosed. Preferably, a diameter of the micropores of about 400 microns is provided. The pore area of the microperforation should be more than 10% of the topcoat area and preferably in the range between 12 and 15%.
Die Anzahl der Mikroporen der Mikroperforation beträgt zwischen 500.000 und 2 Mio. Mikroporen/m2, vorzugsweise zwischen 800.000 und 1,2 Mio. Mikroporen/m2, wobei jeder ganzzahlige Zwischenwert als offenbart gelten soll. Insbesondere ein Wert von ca. 1 Mio. Mikroporen/m2 hat sich bewährt.The number of micropores of the microperforation is between 500,000 and 2 million micro pores / m 2 , preferably between 800,000 and 1.2 million micro pores / m 2 , each integer intermediate value should be considered disclosed. In particular, a value of about 1 million micropores / m 2 has been proven.
Die Tragstruktur kann ein- oder beidseitig mit einem Vliesstoff kaschiert sein, der bereits von sich aus schon eine poröse Struktur aufweist.The support structure may be laminated on one or both sides with a nonwoven fabric, which already has a porous structure of its own accord.

Hierzu wird die Deckschicht 3 mit einem Ummantelungskleber, z.B. einem EVA-Kleber auf die Tragstruktur 2 kaschiert. Die Deckschicht bildet eine Dekorschicht aus einem bedruckbaren oder aus einem bedruckten Dekorpapier. Beispielsweise wird ein Dekorpapier mit 60 g/m2 verwendet. Das Papier kann grundsätzlich ein Flächengewicht zwischen 40 und 180 g/m2 aufweisen.For this purpose, the
Als Deckschicht kann auch ein Holzfurnier oder eine Kunststofffolie, insbesondere eine CPL-Folie (wie Resopal) verwendet werden.As a cover layer, a wood veneer or a plastic film, in particular a CPL film (such as Resopal) can be used.
Die Mikroperforation mit ca. 1 Mio. Mikroporen/m2 erzeugt eine Oberfläche, deren Porenanteil ca. 12 % beträgt. Der Mikroporendurchmesser beträgt dabei vorzugsweise 400 µm. Die Mikroperforation wird mit einem oder mehreren Scanköpfen mit rotierenden Spiegeln erzeugt, wobei das Laserlicht über die rotierenden Spiegel auf die Deckschicht umgeleitet wird. Es können mehrere Laser eingesetzt werden, um die Produktionsgeschwindigkeit zu erhöhen.The microperforation with approx. 1 million micropores / m 2 produces a surface with a pore content of approx. 12%. The micropore diameter is preferably 400 μm. The microperforation is generated with one or more scan heads with rotating mirrors, wherein the laser light is redirected to the cover layer via the rotating mirrors. Multiple lasers can be used to increase the production speed.
Die Tragstruktur 2 kann aus einer Weichfaserplatte, einer Mikro-Strandboard-Platte oder einem sonstigen ummantelungsfähigen Träger bestehen. Das Schüttgewicht liegt vorzugsweise im Bereich von 400 kg/m3.The
Dadurch, dass die Mikroperforation in der Deckschicht 3 nach dem Kaschieren der Tragstruktur 2 erfolgt, kann das Laserlicht insbesondere Klebeschichten zwischen der Deckschicht 3 und der Tragstruktur 2 durchdringen, so dass die schallschluckenden Eigenschaften der akustischen Bauplatte 1 verbessert werden.Due to the fact that the microperforation in the
Da die Erzeugung der Mikroperforation mit dem Kaschierprozess kombiniert werden kann, ist zudem eine kostengünstige und zeitsparende Produktion von Wand- und Deckenpaneelen möglich.Since the production of the micro perforation can be combined with the lamination process, a cost-effective and time-saving production of wall and ceiling panels is also possible.
Die Wand- und Deckenpaneele können an ihren Außenkanten mit formschlüssigen Verbindungselementen, z.B. Nut- und Federelementen und auch mit einrastenden Verbindungselementen (Click-Verbindungen) versehen sein.The wall and ceiling panels may be provided at their outer edges with positive fasteners, e.g. Tongue and groove elements and also be provided with latching fasteners (Click connections).
