Description
Verfahren zum Herstellen kunststoffgebundener, aus Glas-, Mineral- oder Schlackenfasern bestehender Isolierplatten Die Erfindung betrifft ein kontinuierliches Verfahren zum Herstellen kunststoffgebundener Platten aus Glas-, Mineral- oder Schlackenfasern, die be kanntlich ein ausgezeichnetes Isoliermittel gegen Kälte, Wärme und Schall sind. Man stellt sie im kontinuierlichen Verfahren bekanntlich in der Weise her, daß zwischen entweder nach dem Düsenblas- oder dem Schleuderverfahren hergestellte schwebende Fasern ein Bindemittel eingedüst, eine Faserschicht gebildet und diese einer die Dicke der Platten bestimmenden Presse zugeführt wird, in der das Bindemittel aushärtet. Diese Platten haben aber den Nachteil, daß sie nicht wasserdampfdiffusionsfest sind und infolgedessen für die Isolierung von Kühlräumens wie alle porösen Isolierstoffe, Maßnahmen erfordern, die verhindern sollen, daß der Wasserdampf in den Poren kondensiert und so das Isoliervermögen vermindert. Process for the production of plastic-bonded, glass, mineral or slag fibers of existing insulating panels. The invention relates to a continuous Process for the production of plastic-bonded panels from glass, mineral or slag fibers, which are known to be an excellent insulation against cold, heat and noise are. It is known that they are produced in a continuous process in such a way that that between produced either by the nozzle blowing or the centrifugal process floating fibers are injected with a binder, a fiber layer is formed and this is fed to a press which determines the thickness of the plates and in which the binding agent hardens. However, these plates have the disadvantage that they are not resistant to water vapor diffusion and consequently for the insulation of cold rooms like all porous insulating materials, Require measures to prevent the water vapor from condensing in the pores and thus the insulating capacity is reduced.
Die Erfindung besteht jetzt darin, daß als Bindemittel ein aufschäumbarer Kunststoff verwendet wird, der nach Bildung der Faserschicht aufschäumt und verfestigt wird. The invention now consists in the fact that a foamable binder is used as a binder Plastic is used, which foams and solidifies after formation of the fiber layer will.
Es ist bekannt, daß man Kunstharzschaumstoffe verfestigen kann, indem man nach Beendigung des Aufschäumens Glasfasern einrührt und dann den mit den Glasfasern verrührten Kunstharzschaum in Formen gießt und dort erstarren bzw. aushärten läßt. It is known that synthetic resin foams can be solidified by after the end of the foaming, glass fibers are stirred in and then the one with the glass fibers Pour mixed resin foam into molds and solidify or harden there.
Dieses Verfahren hat den Nachteil, daß man die Glasfasern in eine Form bringen muß, in der sie sich gut in den aufgeschäumten Kunststoff einrühren lassen. Sie müssen 2 bis 10 cm lang und dürfen nicht verwirrt sein, wie sie als Isolierwolle anfallen, da sie sonst Klumpen bilden, die keine gleichmäßige Verteilung im Schaum ergeben. Da der Rührprozeß sehr schnell und sorgfältig durchgeführt werden muß und das Erstarren lange dauert, läßt sich dieses Verfahren nicht kontinuierlich durchführen.This method has the disadvantage that the glass fibers in a Must bring form in which they stir well into the foamed plastic permit. They must be 2 to 10 inches long and not be confused as to how to use them Insulating wool accrues, otherwise it will form lumps that cannot be evenly distributed result in the foam. Because the stirring process can be carried out very quickly and carefully must and the solidification takes a long time, this process can not be continuous carry out.
Demgegenüber schlägt die Erfindung ein kontinuierliches Herstellungsverfahren für kunststoffgebundene Isolierplatten vor, bei dem die Glas- od. dgl. In contrast, the invention proposes a continuous manufacturing process for plastic-bonded insulating panels, in which the glass or the like.
Fasern nicht in den Kunststoffschaum eingerührt werden, sondern der aufschäumbare Kunststoff als Bindemittel zwischen die nach dem Düsenblas- oder Schleuderverfahren hergestellten oder sonstwie zum Schweben gebrachten und noch schwebenden Fasern eingedüst wird. Nach dem Ablegen der Fasern auf dem Transportband schäumt der Kunststoff je nach seiner Art in der Kälte oder Wärme auf. Durch eine kontinuierlich arbeitende Presse wird wiederum die Dicke der Platte bestimmt. Nach Verlassen der Presse teilt man das kontinuierliche Glasfaser-Schaumstoff-Uand in Gebrauchsgrößen auf.Fibers are not stirred into the plastic foam, but the foamable plastic as a binder between the blown or centrifugal processes fibers produced or otherwise made to float and still float is injected. After the fibers are placed on the conveyor belt, the plastic foams depending on its type in the cold or warm. Through a continuously working Press, in turn, determines the thickness of the plate. After leaving the press shares the continuous fiberglass-foam-Uand in utility sizes.
Nach dem Verfahren gemäß der Erfindung lassen sich unter Verwendung entsprechender Kunststoffe und Treibmittel sowohl Glasfaser Schaumstoff-Platten mit offenen wie auch besonders solche mit geschlossenen Poren erzeugen. Letztere sind für Kälte-Isolierungen besonders vorteilhaft, da sie eine bei gleicher Isolierwirkung wesentlich höhere Festigkeit aufweisen als nur aus Kunstharzschaumstoffen bestehende Platten und so gut wie nicht brennbar sind, weil die Menge des benötigten Kunstharzschaumstoffes nur gering ist. According to the method according to the invention can be used Appropriate plastics and propellants as well as fiberglass foam sheets with open as well as especially those with closed pores. Latter are particularly advantageous for cold insulation because they have the same insulating effect have significantly higher strength than those made only of synthetic resin foams Sheets and are virtually non-flammable because of the amount of synthetic resin foam required is only slight.
