Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Isoliermaterial, das aus nachwachsenden Rohstoffen, ins besondere Wolle wie Schafwolle, hergestellt und mit einer Borsalzlösung behandelt wird.The invention relates to a method for producing Insulating material made from renewable raw materials, ins special wool like sheep's wool, made and with a Boron solution is treated.
Die Behandlung mit einer Borsalzlösung bezweckt, das Iso liermaterial sicher gegen Feuer und Schädlingsbefall, wie Mottenfraß oder Schimmelbefall zu machen. Bisher wird das Isoliermaterial hierzu nach seiner Verarbeitung zu Matten bzw. Bahnen mit der Borsalzlösung behandelt. Dabei wird die Borsalzlösung auf die Oberfläche der Matten bzw. Bahnen aufgesprüht. Es ergibt sich daher nur ein ver gleichsweise schwacher Oberflächenschutz gegen Brandge fahr, Mottenfraß oder Schimmelbildung. Zudem erfordert der Sprühvorgang einen hohen Überwachungsaufwand, um eine vollständige Oberflächendeckung zu gewährleisten. Ein weiterer Nachteil ist darin zu sehen, daß infolge des le diglich schwachen Oberflächenschutzes eine Reckung bzw. Streckung des Isoliermaterials nur innerhalb enger Gren zen möglich ist, ohne den erforderlichen Schutz zu be schädigen.The purpose of treatment with a boron solution is to isolate the iso liermaterial safe against fire and pest infestation, such as Moth or mold. So far the insulating material for this after its processing Mats or sheets treated with the boron solution. Here the boron solution is applied to the surface of the mats or Sprayed webs. There is therefore only one ver equally weak surface protection against fire driving, moth feeding or mold growth. Also requires the spraying process required a high level of monitoring to ensure complete surface coverage. A Another disadvantage is the fact that due to le weak surface protection a stretching or Extension of the insulation material only within narrow limits zen is possible without the necessary protection damage.
Hiervon ausgehend ist es daher die Aufgabe der vorliegen den Erfindung, unter Vermeidung der Nachteile der bishe rigen Lösungen die Imprägnierung des Isoliermaterials zu verbessern.Based on this, it is therefore the task of the present the invention, while avoiding the disadvantages of the bishe solutions impregnate the insulating material improve.
Diese Aufgabe wird dadurch gelöst, daß das Isoliermateri al in losem Zustand in ein Borsalzlösungsbad eingetaucht wird.This object is achieved in that the insulating material al immersed in a boron solution bath in the loose state becomes.
Die hierbei im Tauchverfahren erzielbare Imprägnierung und damit der hiermit verbundene Schutz gehen in vorteil hafter Weise durch und durch. Dennoch erfordert das er findungsgemäße Tauchverfahren keinen nennenswerten Auf wand. Das lose Isoliermaterial braucht hierzu lediglich in ein Bad eingeworfen zu werden, was wesentlich einfa cher zu bewerkstelligen ist, als ein allseitiges Besprü hen einer aus Isoliermaterial bestehenden Matte. Auch der erforderliche Überwachungsaufwand ist vergleichsweise ge ring, da das erfindungsgemäße Tauchverfahren automatisch eine vollständige, lückenlose Benetzung des Isoliermate rials ergibt. Die erfindungsgemäßen Maßnahmen ergeben demnach eine vergleichsweise hohe Sicherheit. Zudem ist es aufgrund der erfindungsgemäßen Tauchimprägnierung und damit des durch und durch gehenden Schutzes auch ohne weiteres möglich, eine aus derart imprägniertem Material bestehende Matte in die Breite bzw. Länge zu ziehen, ohne das ungeschützte Stellen entstehen können. Die erfin dungsgemäßen Maßnahmen sind daher vor allem dort von be sonderem Vorteil, wo das Isoliermaterial als Stopfmate rial Verwendung findet oder zu Matten verarbeitet wird, die beispielsweise mittels eines Netzes so fixiert sind, daß eine Breiten- bzw. Längenvariation möglich ist. Im Zusammenhang mit dieser Variation läßt sich in vorteil hafter Weise eine hohe Montagefreundlichkeit erreichen. Die erfindungsgemäßen Maßnahmen führen daher auch zu einer ausgezeichneten Wirtschaftlichkeit.The impregnation that can be achieved in the immersion process and thus the protection associated with this is advantageous through and through. Still, he requires it immersion processes according to the invention have no significant value wall. The loose insulation material only needs this to be thrown into a bath, which is essential is to be accomplished as an all-round review hen a mat made of insulating material. Also the required monitoring effort is comparatively ge ring, since the immersion process according to the invention is automatic complete, complete wetting of the insulating mat rials results. The measures according to the invention result therefore a comparatively high level of security. In addition is it due to the dip impregnation according to the invention and thus of thorough protection even without it further possible, one made of such impregnated material to pull the existing mat in the width or length without unprotected areas can arise. The invent Measures according to the invention are therefore primarily from there special advantage where the insulating material as a stuffing mat rial is used or processed into mats, which are fixed, for example, by means of a network, that a width or length variation is possible. in the Connection with this variation can be advantageous achieve a high level of ease of installation. The measures according to the invention therefore also lead to excellent economy.
Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildun gen der übergeordneten Maßnahmen sind in den Unteransprü chen angegeben. So kann das Borsalzlösungsbad zweckmäßig eine Temperatur von 60°C aufweisen. Dies erleichtert die Lösung des Borsalzes und gewährleistet damit eine ausgezeichnete Imprägnierung.Advantageous configurations and practical training General measures are in the subclaims Chen specified. So the boron solution bath can be useful have a temperature of 60 ° C. This makes it easier the solution of the boron salt and thus ensures a excellent impregnation.
Eine weitere vorteilhafte Maßnahme kann darin bestehen, daß das Isoliermaterial nach seiner Verarbeitung zu einem Vlies mittels eines Netzes fixiert, vorzugsweise in einem Netzstrumpf aufgenommen wird. Diese Maßnahme ergibt eine besonders hohe Variabilität, wobei die mit der übergeord neten Lösung verbundenen Vorteile besonders gut zum tra gen kommen.Another advantageous measure can consist in that the insulating material after processing into a Fleece fixed by means of a net, preferably in one Fishnet stocking is included. This measure results in a particularly high variability, with that of the superordinate The advantages associated with the solution are particularly good for tra come.
Weitere zweckmäßige Fortbildungen und vorteilhafte Ausge staltungen der übergeordneten Maßnahmen sind in den rest lichen Unteransprüchen angegeben und aus der nachstehen den Beispielsbeschreibung erkennbar.Further useful training and advantageous Ausge The main measures are in the rest specified subclaims and from the following the example description recognizable.
Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Die Zeichnung zeigt eine schematische Ansicht einer erfindungsgemäßen Iso liermatte.The following is an embodiment of the invention explained in more detail with reference to the drawing. The drawing shows is a schematic view of an ISO protective mat.
Die in der Zeichnung dargestellte Isoliermatte 1 besteht aus einem aus Isoliermaterial hergestellten, bahnförmigen Vlies 2, das durch einen es umgebenden Netzstrumpf 3 fi xiert ist. Die Fixierung durch ein Netz ergibt eine hohe Variabilität in Länge und Breite ohne gleichzeitige Ände rung der Dicke. Im dargestellten Beispiel ist das den Netzstrumpf 3 bildende Netz in Form eines Diagonalnetzes, d. h. mit Maschen mit zu den Seitenflanken der Matte pa rallelen und quer dazu verlaufenden Diagonalen, ausgebil det, was ein hohes Variabilitätsverhältnis in der Größen ordnung von 50-60% ergibt, wie durch die Breitenangaben b bzw. B angedeutet ist. Die lichte Maschenweite kann etwa 50 mm betragen.The insulating mat 1 shown in the drawing consists of a sheet-like fleece 2 made of insulating material, which is fi xed by a net stocking 3 surrounding it. The fixation with a net results in a high variability in length and width without changing the thickness at the same time. In the example shown, the net forming the net stocking 3 is in the form of a diagonal net, ie with meshes with diagonals parallel and transverse to the side flanks of the mat, which results in a high variability ratio in the order of 50-60%, as indicated by the latitudes b and B respectively. The clear mesh size can be about 50 mm.
Das das Vlies 2 bildende Isoliermaterial besteht aus Gründen der Umweltverträglichkeit und zur Gewährleistung einer völligen Unbedenklichkeit in gesundheitlicher Hin sicht aus nachwachsenden Rohstoffen, wie Schurwolle von Schafen. Auch Flachs oder Jute sind denkbar. Diese Materialien müssen durch eine Behandlung mit Borsalz feu ersicher und, sofern es sich um eiweißhaltiges Material wie Wolle, handelt, auch sicher gegen Schädlingsbefall, wie Motten- oder Schimmelbefall, gemacht werden.The insulating material forming the fleece 2 is made of renewable raw materials, such as new wool from sheep, for reasons of environmental compatibility and to ensure complete harmlessness in terms of health. Flax or jute are also conceivable. These materials must be made fire-proof by treatment with boron salt and, if it is a protein-containing material such as wool, must also be made safe against pest infestation, such as moth or mold.
Hierzu wird das das Vlies 2 bildende Isoliermaterial in losem Zustand, d. h. noch vor der Vliesherstellung, in ein eine Borsalzlösung enthaltendes Bad eingetaucht. Hier durch ergibt sich eine durch und durch gehende Benetzung, so daß unabhängig von jeder Art von Dehnung eine hohe Si cherheit erreicht wird. Zur Bewerkstelligung der genann ten Tauchimprägnierung kann das Isoliermaterial in einem seinem Anfall entsprechenden, losen Zustand, oder bei stark verschmutztem Material, nach Durchführung eines Waschvorgangs, in eine eine Borsalzlösung enthaltende Wanne eingeworfen und dort so untergetaucht werden, daß es durch und durch benetzt wird. Die Borsalzlösung wird zweckmäßig auf 60°C erwärmt, was eine gute Lösung des Borsalzes gewährleistet. Hierzu kann die das Bad ent haltende Wanne einfach mit einer geeigneten Heizeinrich tung versehen sein.For this purpose, the insulating material forming the fleece 2 is immersed in a bath, containing a boron solution, in the loose state, ie even before the fleece is manufactured. This results in a continuous wetting, so that a high level of safety is achieved regardless of any type of stretching. To accomplish the so-called immersion impregnation, the insulating material can be thrown into a tub containing a boron solution in a condition that is loose, or in the case of heavily soiled material after carrying out a washing process, and immersed there so that it is thoroughly wetted. The boron salt solution is expediently heated to 60 ° C., which ensures a good solution of the boron salt. For this purpose, the bath containing the bath can simply be provided with a suitable heating device.
Das in vorstehend beschriebener Weise im Tauchverfahren imprägnierte Material wird anschließend getrocknet. Hier zu kann das getauchte Material ausgepreßt und anschließend gelagert werden. Die Trocknungszeit läßt sich durch eine Warmluftbehandlung verkürzen. This in the manner described above in the immersion process impregnated material is then dried. Here the dipped material can be squeezed out and then be stored. The drying time can be checked shorten hot air treatment.
Das getrocknete Material kann in an sich bekannter Weise zu einem mattenförmigen Vlies der bei 2 angedeuteten Art verarbeitet werden. Die Vliesdicke d kann etwa 15 cm be tragen. Diese Dicke ändert sich bei einer Variation der Breite nicht. Es ändert sich lediglich das spezifische Flächengewicht.The dried material can be in a manner known per se to a mat-shaped fleece of the kind indicated at 2 are processed. The fleece thickness d can be about 15 cm wear. This thickness changes with a variation of Don't width. Only the specific changes Basis weight.
