Description

Isolationskörper, insbesondere Wärmedämmplatte Insulation body, in particular thermal insulation board

Die Erfindung betrifft einen Isolationskörper, insbesondere Wärmedämmplatte, aus einem Hartschaummaterial.The invention relates to an insulation body, in particular a thermal insulation board, made of a rigid foam material.

Es ist bereits bekannt, Platten aus Hartschaummaterial verschiedener Konsistenz oder Zusammensetzung herzustellen, die insbesondere auf dem Bausektor für Isolationszwecke eingesetzt werden. Hier erhebt sich die Forderung, den Einsatzbereich solcher Isolationskörper dadurch zu erhöhen, daß sie den bestehenden Vorschriften über die schwerentflammbare Ausbildung von Werkstoffen genügen. Demgemäß liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Isolationskörper aus Hartschaummaterial schwer entflammbar auszubilden.It is already known, sheets of rigid foam material of various To produce consistency or composition, particularly in the construction sector be used for insulation purposes. This is where the requirement arises, the area of application to increase such insulation body by complying with the existing regulations about the flame-retardant construction of materials are sufficient. Accordingly lies the The present invention is based on the object of an insulation body made of rigid foam material to be made flame retardant.

Die gestellte Aufgabe wird unter Erfüllung der für die Einstufung als schwer entflammbare Werkstoffe vorgeschriebenen Bedingungen erfindungsgemäß dadurch erreicht, daß der Isolationskörper eine schwer entflammbare Außenhaut aufweist,.die aus einem Glasfaservlies besteht, das mit einer mindestens ein Metalloxyd enthaltenden Beschichtung versehen ist.The given task will be performed while fulfilling the requirements for the classification as flame-retardant materials prescribed conditions according to the invention achieved in that the insulation body has a flame-retardant outer skin, .die consists of a glass fiber fleece, which with at least one metal oxide containing Coating is provided.

Als Beschichtungsmasse eignet sich vorteilhafterweise mindestens eine weichmacherfreie Dispersion eines Mischpolymerisats auf der Basis von Vinylidenchlorid und/oder Butadien, die als Metalloxyd Aluminiumhydroxyd-und/oder Antimonoxyd enthält.At least one is advantageously suitable as the coating compound plasticizer-free dispersion of a copolymer based on vinylidene chloride and / or butadiene, which contains aluminum hydroxide and / or antimony oxide as the metal oxide.

Die Außenhaut des erfindungsgemäß ausgebildeten Isolationskörpers erbringt eine für Bauzwecke ausreichende und den aufgestellten Vorschriften (DIN 4102-B) entsprechende schwer entflammbare Eigenschaft des Isolationskdrpers, die derzeit verwendetes Hartschaummaterial auf Kunststoffbasis nicht besitzt.The outer skin of the insulation body designed according to the invention provides a sufficient for construction purposes and the established regulations (DIN 4102-B) corresponding flame-retardant property of the insulation body, which currently used rigid foam material based on plastic does not have.

In der getrockneten Beschichtungsmasse kann der Anteil des Mischpolymerisats zwischen 25% und 50% und der Anteil an Metalloxyd zwischen 50% und 75X liegen.The proportion of the copolymer in the dried coating composition between 25% and 50% and the proportion of metal oxide between 50% and 75X.

Die Stärke der Beschichtung kann dem Einsatzzweck entsprechend gewählt werden. Ublicherweise genügt aber eine Beschichtung relativ geringer Dicke, die eine gasdichte Außenhaut ergibt oder aber noch eine relativ geringe Anzahl von Poren in der Außenhaut freiläßt, in welche das Material des Hartschaumkernes des Isoiationskörpers eindringen kann und dadurch die Haftung der Außenhaut auf dem Isolationskörper begünstigt.The thickness of the coating can be selected according to the intended use will. Usually, however, a coating of a relatively small thickness is sufficient results in a gas-tight outer skin or a relatively small one number leaves free of pores in the outer skin, in which the material of the rigid foam core the insulation body can penetrate and thereby the adhesion of the outer skin on favored the insulation body.

Die Herstellung der Außenhaut eines erfindungsgemäß ausgebildeten Isolationskörpers kann erfindungsgemäß in folgenden Verfahrensschritten erfolgen: a) Nischen des mindestens einen Mischpolymerisats mit dem mindestens einen Metalloxyd zu einer homogenen Paste; b) Behandeln der Paste in einem Mixer zum Aufschäumen auf ein Gewicht von ca. 250-500 g/l unter eventueller Zugabe von Pigmentfarbstoffen und anderen Zu satzstoffen; c) Aufstreichen der aufgeschäumten Paste auf das Glasfaservlies mittels einer Rakel, ausgebildet als Luft- oder Streichrakel mit definierter Beschichtungsdicke; d) Trocknen des beschichteten Glasfaservlieses mittels Strahlungswärme.The production of the outer skin of one designed according to the invention According to the invention, the insulation body can be carried out in the following process steps: a) Niches of the at least one copolymer with the at least one metal oxide to a homogeneous paste; b) Treating the paste in a mixer for foaming to a weight of approx. 250-500 g / l with possible addition of pigment dyes and other additives; c) Spreading the foamed paste onto the glass fiber fleece by means of a doctor blade, designed as an air or doctor blade with a defined coating thickness; d) drying the coated glass fiber fleece by means of radiant heat.

Es versteht sich, daß die Beschichtung der Außenhaut weitere, eine flammhemmende Wirkung erhöhende oder ander physikalische Eigenschaften des Isolationskörpers begünstigende Zusatz stoffe enthalten kann, so auch die vorstehend erwähnten Pigmentfarbstoffe, die eine Ausbildung der Außenhaut in Jeder gewünschten Farbe ermöglichen. Ein weiterer Vorteil ist, daß die durch das beschichtete Glasfaservlies gebildete Außenhaut als verlorene Form dienen kann, der Hartschaumkern des Isolationskörpers also in der Außenhaut aufgeschäumt werden kann. Hierbei kann natürlich zusätzlich eine äußere Stützform zur Gewährleistung einer genauen Maßhaltigkeit der Isolationskörper mit eingesetzt werden.It goes without saying that the coating of the outer skin further, one flame-retardant effect increasing or other physical properties of the insulation body may contain beneficial additives, including the pigment dyes mentioned above, which enable the outer skin to be designed in any desired color. Another The advantage is that the outer skin formed by the coated glass fiber fleece as lost shape can serve, so the rigid foam core of the insulation body in the Outer skin can be foamed. Of course, an external one can also be used here Support form to ensure exact dimensional accuracy of the insulation body with can be used.
