Abstract

The technical field of the invention is fire protection; here in particular production of a lightweight fire-retardant board for particular use in air transport where weight problems prevail and where at the same time specific specifications must be fulfilled, as to which temperatures for a minimum time must be able to be withstood. For this purpose, the invention proposes the use of paper strips, paper scraps or other waste paper which are mixed with a special binder made of water glass, kaolin and casein glue. The stability can be further increased by the admixture of wood chips. A production method for obtaining a lightweight board is (also) proposed. In the production process, the liquid/viscous mass of paper strips, kaolin and water glass is first cast in board form and is then dried at an increased temperature and pressed at a further increased temperature. The result is the apparently paradoxical fireproof material made of paper.

Description

Die Erfindung bezieht sich auf einen Werkstoff, der leichtgewichtig und gleichzeitig feuerhemmend ist.The invention relates to a material that is lightweight and fire retardant at the same time.

Besonders für den Lufttransport ist es erwünscht, feuerhemmende Komponenten als Werkstoffe zur Verfügung zu haben, die das Frachtgewicht beim Lufttransport nicht erhöhen. Solche Werkstoffe sind selten, da eine Feuerhemmung meist mit einer Gewichtserhöhung einhergeht; sind sie verfügbar, so erheben sie einen erhöhten Anspruch hinsichtlich der Kosten.Especially for air transportation it is desirable to have fire retardant To have components available as materials that the Do not increase cargo weight during air transportation. Such Materials are rare, as fire retardation usually involves one Weight increase goes hand in hand; if they are available, they charge an increased cost claim.

Dem soll mit der Erfindung gemeinsam abgeholfen werden; sie hat sich zum Ziel gesetzt, einen preisgünstigen, leicht herstellbaren und gleichzeitig feuerhemmenden Werkstoff - insbesondere für den Lufttransport - zu schaffen (Problem).This is to be remedied together with the invention; she has set itself the goal of an affordable, lightweight manufacturable and at the same time fire-retardant material - especially for air transport - to create (problem).

Die Erfindung schlägt dazu vor, Papierschnitzel und Papierstreifen zu verwenden, wie sie z. B. aus herkömmlichen büroüblichen Aktenvernichtern in einer großen Menge anfallen. Sie werden zu dem leichtgewichtigen und stabilen (erfindungsgemäßen) Werkstoff durch Beigabe eines besonderen Binders, den die Erfindung als Wasserglas-Kaolin-Weißleim-Binder bezeichnet (Anspruch 1), verarbeitet. Er besteht aus den genannten Komponenten und setzt sich konkreter aus den in Anspruch 2 genannten Gewichtsprozent-Zahlen zusammen. Zugesetzte Holzspäne erhöhen die Festigkeit (Anspruch 5), nicht dagegen die Kosten.The invention proposes shredded paper and Use paper strips, such as z. B. from conventional office shredders in large quantities. You become the lightweight and stable (invention) material by adding a special Binders, the invention as a water glass kaolin white glue binder designated (claim 1), processed. It consists of the mentioned components and more specifically consists of the in Claim 2 weight percentages together. Added Wood chips increase the strength (claim 5), but not the Costs.

Zur Lösung derselben Aufgabe schlägt die Erfindung die feuerhemmende leichtgewichtige Platte auf Papierbasis (Anspruch 6) vor und hält ein Herstellungsverfahren (auch) für diese gewichtsarme Platte bereit (Anspruch 7).To achieve the same object, the invention proposes fire retardant lightweight paper-based panel (Claim 6) and holds a manufacturing process (also) for this low-weight plate ready (claim 7).

Während die leichtgewichtige Platte auf Papierbasis die Mischung aus Papierschnitzel und einen Weißleim, der mittels Wasser verdünnt wurde, enthält, neben einer Kaolin-Wasserglas- Komponente, nennt das Herstellungsverfahren konkreter diejenigen Schritte, die zum Erhalt einer solchen leichtgewichtigen Platte führen können. Die Papierstreifen - auch bereits recycelte Papiere oder Papierstreifen - werden angefeuchtet und mit einem verdünnten Weißleim vermischt. Nun wird Kaolin und Wasserglas zugegeben, wobei diese beiden Komponenten vor der Zugabe auch gesondert bereits vermischt sein können. Ihr Verhältnis beträgt etwa 30 : 70, wobei das Wasserglas den höheren Anteil hält. Zur Herstellung einer feuerhemmenden und gleichzeitig leichtgewichtigen Platte wird ein Verhältnis der Papierstreifen/Weißleim zu dem Kaolin/Wasserglas von etwa 2 : 1 vorgeschlagen. Wird die zweitgenannte Komponente erhöht, so erhöht sich das Gewicht, wird die erstgenannte Komponente erhöht, so sinkt die Feuerhemmungs-Leistung.While the lightweight paper-based plate the mixture made from shredded paper and a white glue using water diluted, contains, in addition to a kaolin water glass Component, the manufacturing process calls those more specifically  Steps to get such a lightweight plate being able to lead. The paper strips - even recycled ones Papers or strips of paper - are moistened and with a diluted white glue mixed. Now kaolin and water glass added, these two components also before adding can already be mixed separately. Your ratio is about 30:70, with the water glass holding the higher portion. For Making a fire retardant and at the same time lightweight plate becomes a ratio of Paper strips / white glue to the kaolin / water glass of about 2: 1 suggested. If the second component is increased, so if the weight increases, the first-mentioned component becomes increases, the fire retardant performance decreases.

Konkreter nennt Anspruch 8 den Herstellweg der Platte, sie entsteht durch Gießen des flüssigen/zähflüssigen Zwischenproduktes - wie zuvor erwähnt - und anschließendes Trocknen bei etwa 70°C. Daran kann sich eine Pressung bei etwa 90°C anschließen (Anspruch 9, 10).More specifically, claim 8 calls the path of manufacture of the plate, she is created by pouring the liquid / viscous Intermediate - as mentioned before - and subsequent Dry at around 70 ° C. This can cause a pressure at about Connect 90 ° C (claim 9, 10).

Die entstehende Platte ist leichtgewichtig und weist eine für Papierschnitzel ungewöhnliche Feuerhemmung auf, so daß sie besonders für den Anwendungsbereich im Lufttransport Einsatz finden kann.The resulting plate is lightweight and has one for Shredded paper on unusual fire resistance so that it especially for the area of application in air transport Can be found.

Hinsichtlich der feuerhemmenden Leistung sei erwähnt, daß dieser Werkstoff - obwohl er aus Papier entstanden ist - bis etwa 200°C "feuerfest" und bis etwa 700°C feuerhemmend bleiben kann. Er ist damit zwar nicht feuerfest in herkömmlichen Sinn (etwa 1000°C), jedoch reicht es für die Luftfahrt aus, daß eine Feuerhemmung bis zu diesen Temperaturen erreicht wird. Der Werkstoff ist stabil und er kann ohne große Probleme hinsichtlich seiner Bestandteile - auch besonders preisgünstig - hergestellt werden; Papierstreifen und Papierschnitzel gibt es allenthalben, derzeit ist sogar ein Trend zu verzeichnen, daß Altpapier wieder der schon tot geglaubten Verbrennung zugeführt werden muß, da hinreichende Verwertungsmöglichkeiten nicht zugegen sind. Die vorliegende Erfindung schlägt eine solche (neue) Verwendungsmöglichkeit für das stark überhandnehmende Recyclingpapier-Problem vor.Regarding fire retardant performance, it should be noted that this Material - although it was made from paper - up to about 200 ° C "Fireproof" and can remain fire retardant up to about 700 ° C. He is not fire-proof in the conventional sense (about 1000 ° C), however, it is sufficient for aviation that a fire retardant up to these temperatures is reached. The material is stable and he can with no great problems regarding his Components - also particularly inexpensive - are produced; Paper strips and shredded paper are everywhere, currently there is even a trend that waste paper is again the incineration that is believed to be dead must be supplied because sufficient opportunities for exploitation are not available. The The present invention proposes such a (new)  Possible use for the strongly overwhelming Recycled paper problem.

Bislang unerwähnt blieben die weiteren vorteilhaften Eigenschaften der Papierstreifen oder Papierschnitzel enthaltenden Platte. Sie ist neben ihrer preiswerten Herstellung von erheblicher Festigkeit, wozu das Verschlingen der Papierstreifen beiträgt. Die Festigkeit kann durch Beigabe von Holzspänen noch weiter erhöht werden, der Anteil von Holzspänen gegenüber den Papierstreifen sollte allerdings nicht größer als 50% werden. Werden Holzspäne beigemischt, so steigt der Wasserbedarf, dieser kann durch zusätzliches Einmischen von Wasser gedeckt werden, er kann aber auch dadurch eingebracht werden, daß der verdünnte Weißleim einen höheren Wasseranteil erhält. Der Wasseranteil des verdünnten Weißleims kann auch geringfügig abhängig von der Papierart sein, wird saugfähiges Papier verwendet, so wird der Weißleim stärker verdünnt, als bei stark leimhaltigem Papier.The other advantageous ones have not yet been mentioned Properties of paper strips or shredded paper containing plate. It is next to its inexpensive manufacture of considerable strength, for which the devouring of the Paper strips contributes. The strength can be increased by adding Wood chips are increased even further, the proportion of wood chips compared to the paper strips, however, should not be larger than Will be 50%. If wood chips are mixed in, it increases Water requirement, this can be achieved by mixing in Water can be covered, but it can also be brought in through it be that the diluted white glue has a higher water content receives. The water content of the diluted white glue can also being slightly dependent on the type of paper will be absorbent Paper is used, so the white glue is diluted more than with strongly glue-containing paper.

Erwähnt war bereits, daß auch bereits recycelte Papiere oder Papierstreifen, die in der Regel schwer zu reinem Papier wieder verarbeitet werden können, hier ein vorteilhaftes Anwendungsgebiet finden. Sie werden zunächst in längere Schnitzel- oder Streifenform zerlegt und dann mit dem WKW-Binder vermischt. Der WKW-Binder, der aus Weißleim, Kaolin und Wasserglas besteht, enthält bereits die für das jeweilige Papierschnitzel-Gewirr zugeschnittene Wassermenge in Form des wasserverdünnten Weißleims. Eine bevorzugte Mischung des WKW- Binders ist 35 Gew.-% wasserverdünnter Weißleim, wobei die der Papierart entsprechende Wassermenge hier enthalten ist, 45 Gew.-% Wasserglas und 20 Gew.-% Kaolin. Diese Werte verstehen sich als Richtwerte, weshalb die Erfindung sie als "Etwa-Werte" bezeichnet, darunter versteht die Erfindung eine Veränderung von ±5% im Gew.-%-Anteil.It was already mentioned that already recycled papers or Strips of paper that are usually difficult to get pure paper again can be processed, an advantageous here Find application area. You will be in longer first Dismantled chips or strips and then with the WKW binder mixed. The WKW binder made from white glue, kaolin and Water glass exists, already contains that for the respective Paper shredded tangle tailored amount of water in the form of the water-diluted white glue. A preferred blend of WKW Binders is 35% by weight of water-diluted white glue, with the Paper type corresponding amount of water is included here, 45 wt .-% Water glass and 20% by weight kaolin. These values are understood as Guide values, which is why the invention describes them as "approximate values" referred to, the invention understands a change of ± 5% in% by weight.

Etwa 7% des Kaolin-Anteils kann in der oben erwähnten bevorzugten Mischung durch Vermiculit-Pulver oder -Granulat gebildet werden. About 7% of the kaolin content can be found in the above preferred mixture by vermiculite powder or granules be formed.  

Bislang war erwähnt worden, daß die bevorzugte Anwendung der feuerfesten Papierplatte mit WKW-Binder beim Lufttransport liegt, also bei dem Bau von Containern und Transportmitteln, die in der Luftfahrt eingesetzt werden. Daneben gibt es aber andere vorteilhafte Anwendungsgebiete, so in der Bauindustrie bei der Isolierung von Bauten, wie Häusern und Gebäuden. Hier kommt zum Tragen, daß die Platte aus Papierschnitzel und WKW-Binder nicht nur feuerfest, sondern auch wasserdicht und unverrottbar ist. Sie kann damit an die Stelle bisher üblicher Kunststoff-Formplatten oder anderen Kunststoffplatten treten, die zur Isolation beispielsweise des Kellerbereiches von Häusern an der Außenwand verwendet wurden. Obwohl die Ausgangsstoffe dieser Papierplatte es zunächst nicht vermuten lassen würden, daß die Platte nach Trocknung wasserdicht ist, zeigen Versuche, daß sie gegenüber Wassereinbruch unempfindlich ist. Außerdem ist sie wesentlich stabiler als herkömmliche Polystyrol-Platten, wozu auch die zusätzliche Beimischung von Holzspänen beitragen kann. Gegenüber den erwähnten Kunststoff-Platten hat sie schließlich den Vorteil, daß sie aus natürlichen Werkstoffen gefertigt ist, also langfristig umweltverträglich ist. Die zu ihrer Herstellung verwendeten Werkstoffe sind preiswert und bei der derzeitigen Verwertungslage leicht und ohne Verzögerung erhältlich.So far it has been mentioned that the preferred application of the Fireproof paper plate with WKW binder for air transportation lies in the construction of containers and means of transport that be used in aviation. But there are others advantageous areas of application, such as in the construction industry Insulation of structures such as houses and buildings. Here comes to Wear that plate of shredded paper and WKW binder not is only fireproof, but also waterproof and rot-proof. she can thus take the place of conventional plastic mold plates or other plastic sheets that are used for insulation for example the basement area of houses on the outer wall were used. Although the raw materials of this paper plate at first it would not suggest that the plate after Drying is waterproof, trials show that it is opposite Water ingress is insensitive. It is also essential more stable than conventional polystyrene sheets, including the additional admixture of wood chips can contribute. Across from she finally got the plastic plates mentioned Advantage that it is made of natural materials, so is environmentally friendly in the long term. The one for their manufacture Materials used are inexpensive and at the current Recovery position easily available without delay.
