Description

yerfahren zum Herstellen von Platten oder Formteilen aus organischem, faserhaltigem Werkstoff, z. B. Holzspänen, Papierschnitzeln, Stroh od. dgl.y process for the production of panels or molded parts from organic, fibrous material, e.g. B. wood chips, shredded paper, straw or the like.

Es ist bekannt, Gummilösung als Bindemittel und als Bindemittelzusatz für preßfähige Massen aus organischem, faserhaltigem Werkstoff zu verwenden. It is known to use rubber solution as a binder and as a binder additive to be used for compressible masses made of organic, fibrous material.

Auch ist bereits offenbart worden, eine Gummischicht in Zusammenhang mit einer Holzspanplatte zu bringen.A rubber layer has also already been disclosed in connection with this to bring with a chipboard.

Gegenstand der Erfindung ist ein Verfahren zum Herstellen von Platten oder Formteilen, wie Kisten, Behälter, Fässer, Möbel, Gehäuse, z. B. Kühlschränke, und auch von Platten in mehreren Schichten, wobei die Oberflächen einen vorzüglichen Lackträger darstellen, aus organischem, faserhaltigem Werkstoff, wie Holzspänen, Papierschnitzeln, Stroh od. dgl. The invention relates to a method for producing panels or molded parts, such as boxes, containers, barrels, furniture, housings, e.g. B. Fridges, and also of panels in several layers, the surfaces of which are excellent Represent paint carriers, made of organic, fibrous material, such as wood chips, Shredded paper, straw or the like.

Zweck der Erfindung ist es, solche Platten bis zu 5 bis 7 mm Mindesstärke oder Formteile nicht nur mit den üblichen Eigenschaften der starren oder mechanischen Festigkeit und leichter Bearbeitbarkeit auszustatten, sondern sie insbesondere hochwiderstandsfähig, feuchtigkeits- und fäulnisabweisend zu machen. Dazu sollen sie auch hohe Isolierwirkungen und Schalldichtigkeit und schließlich bei allen diesen Voraussetzungen wiederum eine genügende innere Elastizität besitzen, die eine Formveränderung, wie etwa Werfen u. dgl., ausschließt. The purpose of the invention is to produce such panels with a minimum thickness of 5 to 7 mm or molded parts not only with the usual properties of rigid or mechanical To equip them with strength and easy machinability, but in particular they are highly resistant, to make moisture and rot repellent. In addition, they should also have a high insulating effect and soundproofing and finally with all these conditions in turn have sufficient internal elasticity to allow shape change such as throwing and the like, excludes.

Gemäß der Erfindung besteht das Verfahren zum Herstellen von Platten oder Formteilen aus organischem, faserhaltigem Werkstoff, z. B. Holzspänen, Papierschnitzel, Stroh od. dgl., mit Zusatz von härtbarem Bindemittel, z. B. Phenolharzen, darin, daß einer mäßig feuchten, kalten Masse aus diesem faserhaltigen Werkstoff derselben oder unterschiedlichen Art ein Füllstoff aus zerfasertem vulkanisiertem Gummi oder Altgummi sowie außer den härtbaren Bindemitteln in an sich bekannter Weise etwa 100/o Gummilösung beigemischt und das ganze Gemisch in üblicher Weise in Formen od. dgl. unter einem Druck bis zu etwa 60 kg/cm2 und unter Hitzeeinwirkung von 1500 C gepreßt wird. According to the invention there is the method of making panels or molded parts made of organic, fibrous material, e.g. B. wood chips, shredded paper, Straw or the like, with the addition of a hardenable binder, e.g. B. phenolic resins, therein, that a moderately moist, cold mass of this fibrous material of the same or different kinds of a filler made of fiberized vulcanized rubber or Old rubber and in addition to the curable binders in a manner known per se, for example 100 / o rubber solution added and the whole mixture in the usual way in molds or the like under a pressure of up to about 60 kg / cm2 and under the action of heat of 1500 C is pressed.

Erfindungsgemäß kann weiter eine Platte ohne den Zusatz des Füllstoffes aus zerfasertem vulkanisiertem Gummi oder Altgummi fertiggepreßt werden, auf die eine Schicht aus diesem Füllstoff unter Beimischung von Bindemitteln in gewünschter Schichthöhe ohne Pressung aufgebracht wird. According to the invention, a plate can also be used without the addition of the filler from shredded vulcanized rubber or scrap rubber are finished pressed onto the a layer of this filler with admixture of binders in the desired Layer height is applied without pressing.

Schließlich k<5,unen nach der Erfindung abwechselnd ohne Füllstoffzusatz gepreßte Platten mit Füllstoffschichten verbunden werden. Finally, k <5, alternating according to the invention without the addition of fillers pressed panels are connected with layers of filler.

Die Zeichnung zeigt als Beispiel schematisch in Abb. 1 eine Zweischichtenplatte, wobei die untere Schicht 1 aus einer kuustharzgehundenen WIischung v-on Faserstoffen, z. B. Holzspänen mit Stroh, mit Gummilösungszusatz besteht, während die obere Schicht 2 aus zerfasertem, durch Bindemittel ge- bundenem Altgummi in Korn und Faserform gehalten ist, Abb. 2 eine Mehrschichtenausbildung aus zwei Schichten 1 und einer Schicht 2. As an example, the drawing shows schematically in Fig. 1 a two-layer panel, the lower layer 1 being made of a synthetic resin-bonded mixture of fibers, z. B. wood chips with straw, with a rubber solution additive, while the top layer 2 made of shredded, bonded bonded old rubber in grain and fiber form is held, Fig. 2 is a multi-layer construction of two layers 1 and one Layer 2.
