Abstract

A natural or cast stone structural member (1) has protective layer (3) of boron silica glass adhered around the surface of a marble base (2) via adhesive layer (4). The adhesive layer used contain ultraviolet (UV) precipitation hardening adhesive.

Description

Die Erfindung betrifft ein Bauelement aus Natur- oder Kunststein, dessen dekorative Oberfläche eine transparente Schutzschicht aufweist. Bei den zu schützenden Materialien handelt es sich vorzugsweise um poröses carbonatisches Gestein, wie zum Beispiel Marmor, Sand- oder Kalkstein.The The invention relates to a structural element made of natural or artificial stone, the decorative surface has a transparent protective layer. To be protected Materials are preferably porous carbonatic rocks, such as marble, sand or Limestone.

Insbesondere bei der Verwendung von Marmor zur Gestaltung von dekorativen Oberflächen im Sanitärbereich ist es erforderlich, die Oberflächen vor dem Einfluss verfärbender und aggressiver Medien zu schützen. In diesen Anwendungsbereichen ist das Gestein auch an der Oberfläche beschädigenden mechanischen Beanspruchungen ausgesetzt.Especially when using marble for the design of decorative surfaces in the sanitary area it is necessary to use the surfaces against the influence of discoloring and more aggressive media. In these applications, the rock is also on the surface damaging mechanical Exposed to stress.

Zum Schutz von Steinoberflächen ist es bekannt, auf die zu schützenden Oberflächen unterschiedliche Schutzschichten aufzutragen. Dies können härtbare Kunstharzmischungen oder die poröse Steinstruktur sättigende Substanzen sein. Derartige Lösungen sind unter anderem in der DE 33 05 549 A1 und EP 0 604 443 B1 beschrieben. Insbesondere der Schutz der Steinoberflächen vor mechanischer Beanspruchung kann bei den bekannten Lösungen nicht befriedigen.For the protection of stone surfaces, it is known to apply different protective layers to the surfaces to be protected. These may be curable synthetic resin mixtures or the porous stone structure saturating substances. Such solutions are inter alia in the DE 33 05 549 A1 and EP 0 604 443 B1 described. In particular, the protection of the stone surfaces from mechanical stress can not satisfy in the known solutions.

Besonders zum Schutz vor mechanischen Beanspruchungen dienen Lösungen, bei denen auf die zu schützenden Steinoberflächen massive Glasscheiben aufgeklebt werden. Um die nötige Festigkeit der Glasscheiben während der Verarbeitung und dem späteren Gebrauch des Verbundbauteils zu gewährleisten, muss die Glasscheibe eine ausreichend große Dicke aufweisen. Diese notwendige Dicke der Glasscheibe wirkt sich störend auf die optische Wirkung der Gesteinsoberfläche aus und verdrängt den natürlichen Steincharakter, da unter anderem Lichtbrechung und Eigenfarbe des Glases das optische Erscheinungsbild der Steinoberfläche verändern. Außerdem sind die verwendeten Glasscheiben noch zu kratzempfindlich und nicht ausreichend bruchsicher bei Schlageinwirkungen, wie sie zum Beispiel im Sanitärbereich durch das Herunterfallen von harten Gegenständen auftreten können. Die notwendige Dicke der Glasscheiben ist außerdem bei der Ausbildung von sichtbaren Kanten oder dem Anbringen von Fasen und Radien fertigungstechnisch und optisch störend.Especially to protect against mechanical stress solutions, where to be protected stone surfaces glued on massive glass panes. To the necessary strength of the glass panes while the processing and the later To ensure use of the composite component, the glass pane needs to be a big enough one Have thickness. This necessary thickness of the glass pane affects disturbing on the optical effect of the rock surface and displaces the natural Stone character, because among other things light refraction and own color of the Glass change the visual appearance of the stone surface. Besides, they are the used glass sheets are still too sensitive to scratches and not sufficiently break-proof with impact effects, as for example in the sanitary area may occur due to the falling of hard objects. The necessary thickness of the glass is also in the formation of visible edges or the attachment of chamfers and radii manufacturing technology and visually disturbing.

Um die Gefahren beim Zerbrechen derartiger Verbundbauteile zu verringern, wurde vorgeschlagen, zwischen der Glasscheibe und dem Natursteinelement eine transparente Kunststofffolie anzuordnen. Problematisch bei diesen Lösungen ist unter anderem das blasenfreie Verkleben der Folie sowie wiederum die Beeinflussung der Optik durch zusätzliches Brechen des Lichtes. Der Hauptnachteil für die Verwendung im Innenausbau besteht jedoch in der Sichtbarkeit der Kunststofffolien im Randbereich.Around to reduce the risks of breaking such composite components was proposed between the glass pane and the natural stone element to arrange a transparent plastic film. Problematic with these solutions Among other things, the bubble-free bonding of the film and turn the influence of the optics by additional breaking of the light. The main disadvantage for however, interior use is in visibility the plastic films in the edge area.

Daher sind die bekannten Lösungen mit einer aufgeklebten massiven Glasscheibe auch vorzugsweise für die Gestaltung von Fassaden oder ähnlichen Objekten vorgesehen. Speziell für derartige Anwendungen sind Lösungen bekannt, bei denen auf Grund der erforderlichen Dicke der Glasscheibe diese sogar als Tragelement für das gesamte Bauteil eingesetzt wird, und der eigentliche Steinanteil im Verbundbauteil nur noch eine Dekorschicht darstellt. Für die dekorative Gestaltung, zum Beispiel von hochwertigen Badeinrichtungen, sind diese Lösungen jedoch nicht geeignet, da der Steineffekt durch die Dicke der Glasscheibe optisch stark beeinträchtigt wird.Therefore are the known solutions with a glued solid glass also preferably for the design of facades or similar Objects provided. Specially for Such applications are solutions known in which due to the required thickness of the glass pane this even as a supporting element for the entire component is used, and the actual stone content only represents a decorative layer in the composite component. For the decorative Design, for example, of high-quality bathroom facilities, are these solutions however, not suitable because of the stone effect due to the thickness of the glass sheet visually severely impaired becomes.

Der aufgezeigte Stand der Technik ist unter anderem Gegenstand der DE 196 13 439 A1 , DE 195 18 675 C1 , DE 196 09 468 C1 und DE 203 12 253 U1 .The cited prior art is inter alia the subject of DE 196 13 439 A1 . DE 195 18 675 C1 . DE 196 09 468 C1 and DE 203 12 253 U1 ,

Es ist daher Aufgabe der Erfindung, ein Bauteil, vorzugsweise aus Naturstein, mit einer geschützten Sicht- und Gebrauchsfläche zu schaffen, bei welchem die Schutzschicht optisch nahezu nicht wahrnehmbar ist und trotzdem äußerst beständig gegen mechanische und chemische Beanspruchungen ist. Mit der Erfindung sollen insbesondere die Einsatzmöglichkeiten von so genannten empfindlichen Natursteinen im Bad-, Sanitär- und Öffentlichkeitsbereich erweitert werden.It is therefore an object of the invention, a component, preferably made of natural stone, with a protected To create visual and utility area, in which the protective layer is optically almost imperceptible and yet extremely resistant to mechanical and chemical stresses. In particular, with the invention the possible uses of so-called sensitive natural stones in the bathroom, sanitary and public areas be extended.

Diese Aufgabe wird durch ein Bauteil aus Natur- oder Kunststein gelöst, bei dem der Stein die Tragschicht bildet und auf der zu schützenden Steinoberfläche eine extrem dünne Beschichtung aus einer selbst nicht tragstabilen Schicht aus einem Borosilicat-Floatglas ganzflächig mittels transparentem Klebstoff aufgebracht ist.These Task is solved by a component made of natural or artificial stone, in the stone forms the base layer and on the to be protected stone surface an extremely thin one Coating of a not self-supporting layer of a Borosilicate float glass over the entire surface is applied by means of transparent adhesive.

Der Vorteil der Erfindung besteht unter anderem darin, dass durch die Verwendung von sehr dünnem Borosilicat-Floatglas (im Bereich von 1 mm Dicke) und die dadurch mögliche äußerst dünne Ausbildung der Schutzschicht eine unbeeinträchtigte optische Wirkung der Steinoberfläche gewährleistet wird. Dazu trägt weiterhin bei, dass auf Grund der geringen Dicke sowie der vorteilhaften Verarbeitungseigenschaften des Borosilicat-Floatglases bei der Verarbeitung, die transparente Klebstoffschicht ebenfalls äußerst dünn ausgebildet werden kann.Of the Advantage of the invention is, inter alia, that by the Use of very thin Borosilicate float glass (in the range of 1 mm thickness) and thereby possible extremely thin formation of the protective layer an unimpaired optical effect of the stone surface guaranteed becomes. Contributes to this Furthermore, that due to the small thickness and the advantageous Processing properties of the borosilicate float glass during processing, The transparent adhesive layer can also be made extremely thin.

Die geringe Dicke der Schutzschicht und der Klebstoffschicht ermöglichen auch eine optisch einwandfreie Gestaltung und Bearbeitung des Bauteils im Bereich von sichtbaren Kanten, wie dies zum Beispiel bei Waschtischen im Badbereich notwendig ist. Wesentliche Vorteile eines Bauteils mit einer Schutzschicht aus Borosilicat-Floatglas sind die hohe Resistenz speziell gegen Laugen, Säuren und organische Substanzen, die doppelte Kratzfestigkeit gegenüber normalem Floatglas sowie die hohe Homogenität des Glases, durch welche die optischen Strukturen insbesondere von Naturstein hervorgehoben werden.The small thickness of the protective layer and the adhesive layer also allow a visually flawless design and processing of the component in the range of visible edges, as is necessary for example in washbasins in the bathroom area. The main advantages of a component with a protective layer of borosilicate float glass are the high resistance especially against alkalis, acids and organic Substances, the double scratch resistance compared to normal float glass as well as the high homogeneity of the glass, which emphasizes the optical structures of natural stone in particular.

Ein Ausführungsbeispiel der Erfindung ist in der Figur dargestellt. Das Bauelement 1 besteht aus einer Tragschicht 2 aus Marmor, auf welcher mittels einer ganzflächigen, dünnen und transparenten Klebstoffschicht 4 die selbst nicht tragstabile Schutzschicht 3 aus Borosilicat-Floatglas, vorzugsweise Borofloat®, aufgebracht ist.An embodiment of the invention is shown in the figure. The component 1 consists of a base layer 2 made of marble, on which by means of a full-surface, thin and transparent adhesive layer 4 the self-resistant protective layer 3 made of borosilicate float glass, preferably Borofloat ®, is applied.

Die besonderen mechanischen Eigenschaften der aufzubringenden Schutzschicht aus Borosilicat-Floatglas, wie die hohe Biegefähigkeit ermöglichen auch bei Dicken von nur 1 mm ein technologisch vorteilhaftes Aufbringen der Schutzschicht, indem an einem Ende der Tragschicht 2 über deren Breite eine entsprechende Menge Klebstoff wulstartig aufgebracht wird, und die Schutzschicht 3 nach dem Auflegen in diesem Bereich, sich durch ihr Eigengewicht, den Klebstoff entgasend vor sich her verdrängend an die Oberfläche der Tragschicht 2 anschmiegt. Dadurch ist eine blasenfreie Klebstoffschicht ohne Anpresswerkzeuge realisierbar.The special mechanical properties of the applied protective layer of borosilicate float glass, such as the high bending ability allow even at thicknesses of only 1 mm, a technologically advantageous application of the protective layer by at one end of the support layer 2 over the width of which a corresponding amount of adhesive is applied bead-like, and the protective layer 3 After placing in this area, by its own weight, the adhesive degassing in front of him displacing to the surface of the support layer 2 snugly. As a result, a bubble-free adhesive layer without pressing tools can be realized.

Bei den in der Figur dargestellten Dickenverhältnissen ist insbesondere an der rechts angedeuteten Fase erkennbar, dass die Klebstoffschicht 4 und die Schutzschicht 3 den optischen Eindruck eines massiven Steins nicht beeinträchtigen können.In the case of the thickness ratios shown in the figure, it can be seen, in particular on the chamfer indicated on the right, that the adhesive layer 4 and the protective layer 3 can not affect the visual impression of a solid stone.
