The concentration is set to give a bleeder resistor of = 10 9>ohm. The non-flammable additive is an alkali- or earth alkali- or ammonium-pyrophosphate in a concentration of +- 20 wt.%.

Description

Die Erfindung betrifft einen Sack mit einer zumindest überwiegend aus Papiermaterial gebildeten Wandung, wobei das Papiermaterial durch Zugabe eines leitfähigen Salzes antistatisch ausgerüstet ist.The The invention relates to a bag with an at least predominantly formed from paper material wall, wherein the paper material by adding a conductive Salt antistatic equipped is.

Die Erfindung betrifft ferner die Verwendung eines Flammenschutzmittels als Zusatz zu Papiermaterial.The The invention further relates to the use of a flame retardant as an addition to paper material.

Säcke werden üblicherweise aus Papiermaterial, beispielsweise Kraftpapier, hergestellt. Dabei kann die Wandung eines Sackes aus mehreren Papierlagen bestehen, zwischen denen häufig auch eine Kunststofflage als Feuchtigkeitssperre eingelegt ist.Bags are usually made of paper material, such as kraft paper. It can the wall of a sack consist of several layers of paper, between often Also, a plastic layer is inserted as a moisture barrier.

Derartige Säcke dienen als Transportverpackung für Schüttgüter unterschiedlichster Art. Demzufolge werden derartige Säcke auch in explosionsgefährdeten Umgebungen verwendet. Daher ist es für zahlreiche Anwendungsfälle wichtig, dass das Material der Sackwandungen keine statischen elektrischen Aufladungen unterworfen ist, die sich in Form eines Funkens entladen und daher eine Explosion o. dgl. auslösen könnten.such Serve sacks as transport packaging for Bulk materials of various kinds Art. As a result, such bags are also at risk of explosion Environments used. Therefore, it is important for many applications that the material of the bag walls no static electrical Subject to discharges that discharge in the form of a spark and therefore an explosion or the like could trigger.

Es ist daher bekannt, das Papiermaterial von Sackwandungen antistatisch auszurüsten. Von einer antistatischen Ausrüstung spricht man dann, wenn der Ableitwiderstand des Papiermaterials < 109 Ω ist. Die antistatische Ausrüstung eines derartigen Sackmaterials lässt sich in bekannter Weise durch die Zugabe von geeigneten leitfähigen Salzen herstellen, die leicht dissoziieren und neutral sein sollten, wie beispielsweise Natriumsulfat.It is therefore known to provide the paper material of bag walls antistatic. An anti-static equipment is used when the discharge resistance of the paper material is <10 9 Ω. The antistatic finish of such a sack material can be prepared in a known manner by the addition of suitable conductive salts which should be readily dissociated and neutral, such as sodium sulfate.

Es ist bekannt, Zellulosematerialien, insbesondere Holz und Textilien, flammhemmend auszubilden, indem die Materialien mit einem Flammschutzmittel versetzt werden. Die Flammschutzmittel haben die Funktion, bei auftretenden höheren Temperaturen chemisch so zu reagieren, dass etwa gebildete Flammen erstickt werden, beispielsweise indem bei der Reaktion des Flammschutzmittels CO2 entsteht. Eine andere Art von Flammschutzmittel setzt bei der Reaktion Wasser frei, das die Verbrennung behindert. Bekannte flammhemmende Zusatzstoffe sind Halogen-, Phosphor-, Bor- oder Stickstoffverbindungen. Geeignet sind beispielsweise Pyrophosphate (Diphosphate).It is known to form cellulosic materials, especially wood and textiles, flame retardant by the materials are mixed with a flame retardant. The flame retardants have the function of chemically reacting at higher temperatures occurring so that any formed flames are stifled, for example by CO 2 is formed in the reaction of the flame retardant. Another type of flame retardant releases water during the reaction, which hinders combustion. Known flame retardant additives are halogen, phosphorus, boron or nitrogen compounds. Suitable examples are pyrophosphates (diphosphates).

Es ist nicht üblich, Sackmaterialien mit flammhemmenden Zusätzen zu versehen, weil Papiersäcke in gemäßigten Klimazonen eine ausreichende Restfeuchte besitzen, durch die eine Entflammung von Haus aus erschwert ist. Die intrensische flammhemmende Eigenschaft von zu einem Sack verarbeiteten Papiermaterialien geht nur dann verloren, wenn der Sack längere Zeit in sehr trockenen und warmen Umgebungsbedingungen gelagert wird.It not usual, To provide bag materials with flame-retardant additives, because paper sacks in temperate climates have sufficient residual moisture through which a fire made difficult by the house. The intrinsic flame retardant property of sack-processed paper materials is lost only if the bag is longer Time is stored in very dry and warm ambient conditions.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen antistatisch ausgerüsteten Sack mit einem Zusatznutzen zu versehen.Of the present invention is based on the object, an antistatic equipped To provide bag with an added benefit.

Zur Lösung dieser Aufgabe ist erfindungsgemäß ein Sack der eingangs erwähnten Art dadurch gekennzeichnet, dass das Papiermaterial mit einem Flammschutzmittel in einer solchen Konzentration versetzt ist, dass der Ableitwiderstand < 109 Ω ist.To achieve this object, a bag of the type mentioned above is characterized in that the paper material is mixed with a flame retardant in such a concentration that the discharge resistance is <10 9 Ω.

Der erfindungsgemäße Sack enthält somit lediglich ein Additiv, mit dem sowohl die antistatische Ausbildung als auch eine flammhemmende Eigenschaft erzielt wird.Of the bag according to the invention contains thus only an additive with which both the antistatic training as well as a flame-retardant property is achieved.

Dies wird dadurch erreicht, dass für die antistatische Ausbildung des Sackmaterials nicht ein herkömmliches Salz verwendet wird, sondern ein Additiv, das als Flammschutzmittel geeignet ist. Dieses Additiv muss allerdings in einer hohen Konzentration zugegeben werden, die im Allgemeinen höher liegt als die übliche Zugabekonzentration für die üblicherweise verwendeten Salze zur Ausbildung eines antistatischen Sackes. Demgemäß ist bei der Zugabe des Flammschutzmittels darauf zu achten, dass die Konzentration so hoch ist, dass der Ableitwiderstand < 109 Ω ist. Erfindungsgemäß lässt sich ein Ableitwiderstand von ≤ 108 Ω erreichen.This is achieved by using not a conventional salt for the antistatic formation of the sack material, but an additive which is suitable as a flame retardant. However, this additive must be added in a high concentration, which is generally higher than the usual addition concentration for the commonly used salts to form an antistatic bag. Accordingly, care should be taken when adding the flame retardant that the concentration is so high that the leakage resistance is <10 9 Ω. According to the invention, a leakage resistance of ≦ 10 8 Ω can be achieved.

Die vorliegende Erfindung geht daher von der Erkenntnis aus, dass ein als Flammschutzmittel verwendbares Salz in einer genügend hohen Konzentration auch zur antistatischen Ausbildung des Papiersackmaterials geeignet ist. Demgemäß ist der erfindungsgemäße Papiersack mit der Zugabe eines einzigen Additivs nicht nur antistatisch sondern auch flammhemmend ausgerüstet. Der entsprechende Sack ist daher beispielsweise für den Export in trockene und warme Klimazonen geeignet, weil er auch dort – anders als die herkömmlichen Papiersäcke – flammhemmende Eigenschaften aufweist.The The present invention is therefore based on the recognition that a as a flame retardant usable salt in a sufficiently high Concentration also for the antistatic formation of the paper bag material suitable is. Accordingly, the paper bag according to the invention with the addition of a single additive not only antistatic but also flame-retardant. The corresponding bag is therefore for example for export in dry and warm climates, because he is there - different as the conventional ones Paper sacks - flame retardant Features.

Das Flammschutzmittel ist vorzugsweise ein anorganisches Halogen-, Phosphor- oder Borsalz oder ein Stickstoffverbindungen enthaltendes Salz. Bevorzugt ist die Verwendung eines Alkali-, Erdalkali- oder Ammoniumpyrophosphats.The Flame retardant is preferably an inorganic halogen, phosphorus or boron salt or a salt containing nitrogen compounds. Preferably, the Use of an alkali, alkaline earth or ammonium pyrophosphate.

Die Zugabe des Flammschutzmittels erfolgt mit einer Konzentration von vorzugsweise ≥ 20 Gew.%, bezogen auf das Papiermaterial.The Add the flame retardant with a concentration of preferably ≥ 20% by weight, based on the paper material.

Der Kern der vorliegenden Erfindung liegt somit in der Verwendung eines Flammschutzmittels als Zusatz zu einem Papiermaterial, das zumindest als überwiegende Komponente zur Herstellung einer Sackwandung dient, wobei die Zugabe in einer solchen Konzentration erfolgt, dass der Ableitwiderstand des Papiermaterials < 109 Ω, vorzugsweise ≤ 108 Ω beträgt.The core of the present invention thus lies in the use of a flame retardant as an additive to a paper material, at least as a predominant component for the preparation of a Sack wall is used, wherein the addition is carried out in such a concentration that the bleeder resistance of the paper material is <10 9 Ω, preferably ≤ 10 8 Ω.

Die Zugabe des Flammschutzmittels in der erfindungsgemäßen Konzentration erfordert eine gewisse Sorgfalt, da das üblicherweise geleimte Papiermaterial die wässrige Lösung des Salzes nur zögernd aufnimmt.The Addition of the flame retardant in the concentration according to the invention requires a certain care, since the usually sized paper material the watery solution of salt only hesitantly receives.
