Description
Leichtstoff-, insbesondere Schaumstoffverbundkörper mit emaillierter Metalldeckschicht Leichtstoffverbundkörper mit einem von Deckschichten begrenzten Stützstoffkern sind bekannt. Als Stützstoffkern können dabei die mannigfaltigsten leichten, jedoch genügend festen Werkstoffe verwendet werden, z. B. aus Holz-, Schilf-, Torf- oder Strohfasern bestehende Filze, mit Hilfe von Bindemitteln verpreßte Holzfasern, Porenbeton und insbesondere auch harte Kunststoffschäume. Als Werkstoffe für die dünnen Deckschichten sind insbesondere Stahl, Leichtmetall, Sperrholz, Schichtpreßstoffe und Pappe bekanntgeworden.Lightweight, in particular foam composite body with enamelled Metal cover layer Lightweight composite body with one bordered by cover layers Support core are known. The most diverse light, but sufficiently strong materials are used, e.g. B. made of wood, reed, Felts consisting of peat or straw fibers, wood fibers compressed with the help of binders, Aerated concrete and especially hard plastic foams. As materials for the thin cover layers are in particular steel, light metal, plywood, laminated materials and cardboard became known.
Wesentlich für die Festigkeit des Verbundkörpers ist die gute Haftung zwischen dem Leichtstoffkern und der Deckschicht, welche beide in der Regel miteinander verklebt werden. Bei Verbundkörpern mit einem Schaumstoffkern sind in jüngster Zeit solche auf Grundlage von Polyurethan-Schaumstoffen von Bedeutung geworden, wobei die Kerne innerhalb einer aus den Deckschichten vorgefertigten Hohlkonstruktion durch Auftreiben eines flüssigen, schaumfähigen Reaktionsgemisches erzeugt werden können. Dabei ist die eigene Haftfähigkeit des SchaumstoWes an den Deckschichten in vielen Fällen bereits ausreichend groß, ansonsten sieht man zusätzlich noch einen Klebstoff vor. mit dem die Deckschichten vor dem Aufschäurnen der Reaktionsmasse eingestrichen worden sind. Good adhesion is essential for the strength of the composite body between the light material core and the cover layer, which both are usually connected to each other be glued. Recently, composite bodies with a foam core those based on polyurethane foams have become important, with the cores within a hollow structure prefabricated from the cover layers can be generated by expelling a liquid, foamable reaction mixture can. The foam's own ability to adhere to the outer layers is important in many cases already big enough, otherwise you can also see one Glue before. with which the cover layers before the foaming of the reaction mass have been painted.
Verwendet man jedoch emaillierte Deckschichten, so besteht sowohl für die Verklebung von Deckschicht und vorgefertigtem Leichtstoff als auch für den Fall des Aufschäumens eines schaumfähigen Reaktionsgemisches innerhalb emaillierter Oeckschichten die Schwierigkeit, eine befriedigende Haftfähigkeit des Klebers bzw. eine zuverlässige Eigenhaftfähigkeit des schaumfähigen Reaktionsgemisches zu erzeugen. Die Dauerstandfestigkeit einer Verbundhonstruktion ist aber vornehmlich von der einwandfreien Verbindung der tragenden Außenkonstruktion mit dein abstützenden Leichtstoffkern abhängig. Diese Verbindung muß den auftretenden Differenzspannungen bei Belastungen aller Art und bei Temperaturwechsel zwischen Deckschicht und Stützkern gewachsen sein. Die Ob erfläche von Email ist sehr glatt, porenfrei und glasig, so daß Kleber aller Art oder SchaumstoGreaktionsgemische keine ausreichende Verankerungsfähigkeit im Email finden können. However, if enamelled cover layers are used, both for bonding the top layer and prefabricated lightweight material as well as for the Case of the foaming of a foamable reaction mixture within enamelled Oeckschichten the difficulty of a satisfactory adhesion of the adhesive or to produce a reliable inherent adhesiveness of the foamable reaction mixture. The long-term stability of a composite structure is primarily of the flawless connection of the load-bearing outer construction with your supporting lightweight material core addicted. This connection must be able to withstand the differential voltages occurring under loads of all kinds and grown with temperature changes between the top layer and the support core be. The surface of the enamel is very smooth, pore-free and glassy, so that glue of all types or foam reaction mixtures do not have sufficient anchorage capacity can be found in the email.
Gegenstand der Erfindung ist nunmehr ein Leichtstoff-, insbesondere Schaumstoffverbundkörper mit emaillierter Metalldeclischicht, wobei die dem Leichtstoff zugekehrte Seite der Deckschicht körnige oder fasrige Haftmittel im Email eingebrannt enthält. The invention is now a lightweight material, in particular Foam composite body with enamelled metal decorative layer, with the lightweight material facing side of the top layer granular or fibrous adhesive burnt into the enamel contains.
Die Verbundkörper gemäß der Erfindung können so gestaltet sein, daß der Leichtstoff einseitig oder beidseitig mit Deckschichten versehen ist. Als Platten oder schalenförmige Körper können sie auch einen zur Querrichtung unsymmetrischen Schichtaufbau aufweisen. The composite bodies according to the invention can be designed so that the lightweight material is provided with cover layers on one or both sides. As plates or bowl-shaped bodies, they can also be asymmetrical to the transverse direction Have layer structure.
Körnige Haftvermittler sind beispielsweise Blähton, Ziegelsplitt, expandierter Glimmer oder andere dem Brennprozeß widerstehende, vorzugsweise poröse Materialien mit einer vorzugsweisen Korngröße von 1 bis 4 mm. Fasrige Haftvermittler können beispielsweise Asbest-, Glas- oder Steinwollfasern sein. Granular adhesion promoters are, for example, expanded clay, brick chippings, expanded mica or other, preferably porous, resistant to the firing process Materials with a preferred grain size of 1 to 4 mm. Fibrous adhesion promoters can for example be asbestos, glass or rock wool fibers.
Die körnigen Haftvermittler oder die fasrigen Haftvermittler können als Einzelfaser oder als Faservlies in das nasse Email eingebracht werden. Die dauerhafte Einbettung ist bei ein- oder mehrmaligem Brennen gewährieistet. Die zu emaillierenden ebenen oder profilierten Bleche oder Blechhohlkörper aus Stahl-oder Leichtmetall können liegend bestreut oder belegt und ohne Schwierigkeiten mit dem körnigen oder fasrigen Streugut versehen, flach, gestürzt oder hängend gebrannt werden, wobei nach dem Brennprozeß die für die erwünschte Steigerung erforderliche Haftvermittlermenge fixiert bleibt. Überschuß fällt ab. The granular adhesion promoter or the fibrous adhesion promoter can be introduced into the wet enamel as a single fiber or as a fiber fleece. The permanent one Embedding is guaranteed with single or multiple firing. The ones to be enamelled flat or profiled sheets or hollow sheet metal bodies made of steel or light metal can be sprinkled or topped lying down and without difficulty with the granular or fibrous grit, burned flat, overturned or hanging, whereby after the firing process, the amount of adhesion promoter required for the desired increase remains fixed. Excess falls off.
F i g. 1 zeigt im Querschnitt ein Blech 1 mit Email 2, in dem ein körniger Haftvermittler 3 verankert ist. F i g. 1 shows in cross section a sheet metal 1 with enamel 2, in which a granular adhesion promoter 3 is anchored.
Beim Aufbringen einer Kleberschicht für das Verbinden von Deckschicht und Leicbtstoffkern oder beim Einschäumen von Verbuncti örpern verankert sich der Kleber oder das auftreibende Schaumstoffgemisch intensiv in und um den räumlich aus der Emailschicht herausragenden körnigen oder fasrigen Haftvermittler, so daß die Berührungszone oder sogenannte Randzone zwischen den emaillierten Metalldeckschichten und dem Leichtstoffstützkern eine gleich hohe oder höhere Schub-, Druck- oder Zugfestigkeit als die des Leichtstoffkerninneren erhält und damit die notwendige Wirkung des Leichtstoffes als Stützelement für die tragende emaillierte Sandwich-Deckschicht erreicht werden kann. When applying an adhesive layer for connecting the top layer and glue core or when foaming composite bodies the anchors Glue or the expanding foam mixture intensively in and around the room granular or fibrous adhesion promoter protruding from the enamel layer, so that the contact zone or so-called edge zone between the enamelled metal cover layers and the lightweight material support core equal or higher thrust, Compressive or tensile strength than that of the light material core interior and thus the necessary effect of the lightweight material as a support element for the load-bearing enamelled Sandwich top layer can be achieved.
Körnige oder fasrige Haftvermittler sind für Stahl-und Leichtmetallemaillierungen anwendbar, wobei keinerlei Einschränkung hinsichtlich der Blechdicke gemacht zu werden braucht. Besonders erwähnenswert sind Verbundkörper aus in situ aufschäumenden Polyurethan-Schaumstoff bildenden Gemischen mit oder ohne Klebervorbehandlung der Deckschicht. Granular or fibrous adhesion promoters are used for steel and light metal enamelling applicable, with no restriction made with regard to the sheet thickness needs to be. Composite bodies made from foaming in situ are particularly worth mentioning Polyurethane foam-forming mixtures with or without adhesive pretreatment Top layer.
F i g. 2 zeigt im Querschnitt einen Verbundkörper, wobei wiederum 1 das Blech, 2 die Emailschicht, 3 den körnigen Haftvermittler und 4 den Leichtstoffkern darstellt. F i g. 2 shows a composite body in cross-section, with again 1 the sheet metal, 2 the enamel layer, 3 the granular adhesion promoter and 4 the lightweight core represents.
