Description
Die Erfindung betrifft eine Dämmplatte bestehend aus normalentflämmbarem Hartschaumstoff, der mit flammwidrigen Papieren beschichtet ist.The invention relates to an insulation board consisting of normal scorchable Rigid foam made with flame retardant Paper is coated.
Im Bauwesen sind Dämmplatten aus Hartschaum, die mit Aluminiumfolie oder Asbestpapier beschichtet sind, bekannt. (PoIyurethan-Polyisocyanurat-Dämmplatten,beidseitig mit Aluminium kaschiert, "Thanex 2OOO", der Fa. Thanex-Polyurethan-Chemie, Viersen). Die Platten sind verhältnismäßig teuer. Obwohl der Gedanke nahezuliegen scheint, Hartschaumstoff mit preiswerten flammwidrigen Papieren zu beschichten, wurde er bis jetzt noch nicht verwirklicht, da erhebliche Schwierigkeiten auftreten. Bei der Herstellung einer Dämmplatte durchtränkt das Reaktionsgemisch das Papier; andererseits führt, bedingt durch das Flammschutzmittel, der hohe Feuchtigkeitsgehalt des Papiers zu einer schlechten Haftung zwischen Hartschaumstoff und Papier; in vielen Fällen bilden sich Blasen in der Grenzschicht.In the building industry, insulation boards are made of rigid foam with aluminum foil or coated asbestos paper are known. (Polyurethane-polyisocyanurate insulation boards, on both sides laminated with aluminum, "Thanex 2OOO", from Thanex-Polyurethan-Chemie, Viersen). The plates are relatively expensive. Although the thought seems obvious, rigid foam Coating with inexpensive, flame-retardant papers has not yet been implemented, as it is considerable Difficulties arise. When producing an insulation board, the reaction mixture soaks the paper; on the other hand Due to the flame retardant, the high moisture content of the paper leads to a poor Adhesion between rigid foam and paper; in many cases, bubbles form in the boundary layer.

Aufgabe der Erfindung ist es, normal entflammbare Dämmplatten aus Hartschaumstoff zu entwickeln, die die im Bauwesen geforderten Vorschriften, insbesondere bezüglich des Brandverhaltens, erfüllen, die nicht mit einer Aluminiumfolie beschichtet und preiswerter sind und die mit flammwidrigen Papieren als Oberflächenbeschichtung einwandfrei verbunden sind.The object of the invention is to provide normally flammable insulation boards To develop from rigid foam that the regulations required in the building industry, in particular with regard to the reaction to fire, which are not coated with an aluminum foil and are cheaper and which are flame-retardant Papers are perfectly connected as a surface coating.
Diese Aufgabe wird dadurch gelöst, daß die flammwidrigen Papiere auf der dem Hartschaumstoff zugewandten Seite mit Polyäthylen oder Polyvinylalkohol beschichtet sind.This object is achieved in that the flame-retardant Papers are coated with polyethylene or polyvinyl alcohol on the side facing the rigid foam.
Die erfindungsgemäßen Dämmplatten sind geeignet zur Isolierung von Wänden, Dächern und Fußböden. Sie lassen sich problemlos herstellen; ein gut haftender blasenfreier Verbund zwischen Hartschaumstoff und den flammwidrigen Papieren wird erreicht. Die Dämmplatten sind preisgünstig und als normalentflammbar einzustufen. Die Bezeichnung "normalentflammbar" ist im Entwurf der DIN 4102 Teil 1 definiert. Nach dieser Norm gehört eine erfindungsgemäße Dämmplatte zur Baustoffklasse B 2.The insulation boards according to the invention are suitable for insulating walls, roofs and floors. You let yourself manufacture easily; a well-adhering, bubble-free bond between rigid foam and the flame-retardant papers is achieved. The insulation boards are inexpensive and can be classified as normally flammable. The term "normally flammable" is defined in the draft of DIN 4102 Part 1. According to this standard, an insulation board according to the invention belongs to building material class B 2.
Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Dämmplatte besteht der Kern aus einem Polyisocyanurat-Polyurethan-Hartschaumstoff mit überwiegend Polyisocyanurat-Gruppen der nach DIN 4102.1 zur Klasse B 2 gehört und aus salzhaltigen, vorzugsweise sulfat- oder phosphathaltigem Natronkraftpapier. Derartige Papiere haben ein Flächengewicht von 60 bis 200 g /m2, der Gehalt an Salzen beträgt 1 bis 18 %. Das Papier ist einseitig mit Kunststoff beschichtet, vorzugsweise werden 10 bis 80 g/m Kunststoff aufge-In a preferred embodiment of the insulation board according to the invention, the core consists of a polyisocyanurate-polyurethane rigid foam with predominantly polyisocyanurate groups belonging to class B 2 according to DIN 4102.1 and of salty, preferably sulfate or phosphate-containing soda kraft paper. Such papers have a basis weight of 60 to 200 g / m 2 , the salt content is 1 to 18%. The paper is coated with plastic on one side, preferably 10 to 80 g / m plastic.

Wird die kunststoffbeschichtete Seite noch durch eine Corona-Entladung behandelt, erhöht sich die Haftfestigkeit zum Schaumstoff.brings. The plastic is particularly polyethylene or polyvinyl alcohol suitable. If the plastic-coated side is treated with a corona discharge, it is increased the adhesive strength to the foam.
Polyisocyanuratschaumstoffe sind immer in die Klasse B2 oder B1 einzuordnen. Sie sind beispielsweise in Kunststoffe (1972), S. 731 f beschrieben und beispielsweise als "Hexafoam ^*1 (ICI, Manchester) oder "Baymer " (Bayer AG, Leverkusen) im Handel.Polyisocyanurate foams are always classified in class B2 or B1. They are described, for example, in Kunststoffe (1972), p. 731 f, and are commercially available, for example, as "Hexafoam ^ * 1 (ICI, Manchester) or" Baymer "(Bayer AG, Leverkusen).
Ein normalentflammbarer Polyurethanschaumstoff kann beispielsweise aus dem Polyol BP 401/100-35 der Kali-Chemie, Hannover und Polyphenylpolymethylenpolyisocyanat unter Verwendung üblicher Katalysatoren wie Triäthylamin, Dimethylbenzylamin und ähnlichen sowie Treibmittel wie Wasser, Trichlorfluormethan, Dichlorfluormethan hergestellt werden.A normally flammable polyurethane foam can, for example from the polyol BP 401 / 100-35 from Kali-Chemie, Hanover and polyphenylpolymethylene polyisocyanate under Use of conventional catalysts such as triethylamine, dimethylbenzylamine and the like as well as propellants such as water, trichlorofluoromethane, dichlorofluoromethane will.
