Abstract

The invention relates to a method for producing shaped bodies, especially plates, out of particles having a surface with a wax layer, especially straw, hemp stalks, maize stalks, grape vine stalks or such like, which are dispersed to form a non-woven mat and then pressed into a shaped body. According to the method the particles are first ground up in a single process step, heated in a next step and ground again in a subsequent step. Lastly the particles obtained in the second grinding step are mixed with a binder.

Description

Verfahren zum Herstellen von Formkörpern Process for the production of moldings
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen von Form- körpern, insbesondere von Platten, aus Teilchen mit einer eine Wachsschicht aufweisenden Oberfläche, insbesondere Stroh, Hanf-, Mais-, Weinrebenstengeln oder dergleichen, die zu einem Vlies gestreut und anschließend zu dem Formkörper verpreßt werden.The present invention relates to a method for producing shaped bodies, in particular plates, from particles with a surface having a wax layer, in particular straw, hemp, maize, grapevine stems or the like, which are scattered to form a nonwoven and then pressed to form the shaped body become.
Ein Verfahren dieser Art ist aus der DE-OS 3 021 455 bekannt. Bei diesem Verfahren werden die Teilchen zunächst in einem ersten Verfahrensschritt durch Häckseln zerkleinert, woraufhin sie in einem zweiten, sich daran anschließenden Verfahrensschritt zu Spanfasern aufgeschlossen werden.A method of this type is known from DE-OS 3 021 455. In this method, the particles are first comminuted by chopping in a first process step, whereupon they are broken down into chip fibers in a second process step that follows.
In einem weiteren, sich daran anschließenden Verfahrensschritt werden die Spanfasern getrocknet, woraufhin die getrockneten Spanfasern mit Bindemittel sowie einer Paraffinemulsion versetzt werden.In a further, subsequent process step, the chip fibers are dried, whereupon binder and a paraffin emulsion are added to the dried chip fibers.
Die auf die Weise beleimten Teilchen werden in einem weiteren Verfahrensschritt nachzerkleinert, wobei die Nachzerkleinerung der beleimten Teilchen wesentlich für das in dieser Druckschrift beschriebene Verfahren ist. Es ist nämlich angegeben, daß durch das Nachzerkleinern der beleimten Teilchen die Anzahl jener Teilchenoberflächen, die beim Verpres- sen des Vlieses die spätere Verleimung ungünstig beeinflussen, in erheblichem Maße verringert werden. Gleichzeitig wird während des Nachzerklei- nerns das Bindemittel durch den vom Spanbeleimen bekannten Wischef- fekt noch besser an allen nunmehr vorhandenen Flächen der Teilchen verteilt und damit weiter vergleichmäßigt.The particles glued in this way are re-comminuted in a further process step, the re-comminution of the glued particles being essential for the process described in this document. It is stated that the size reduction of the glued particles significantly reduces the number of particle surfaces which adversely affect the subsequent gluing when the fleece is pressed. At the same time, the binder is removed during the shredding by the wiping process known from chip gluing. even better distributed on all surfaces of the particles now present and thus further evened out.
Durch das in der DE-OS 3 021 455 beschriebene Verfahren werden zwar Platten mit guten Festigkeitseigenschaften erzeugt, es ist jedoch eine relativ hoher Anteil an Bindemittel sowie die Zugabe einer Paraffinemulsion erforderlich. Weiterhin sind relativ viele separate Verfahrensschritte erforderlich, wobei jeder Verfahrensschritt die Kosten des Verfahrens erhöht.Although the process described in DE-OS 3,021,455 produces plates with good strength properties, a relatively high proportion of binder and the addition of a paraffin emulsion are required. Furthermore, a relatively large number of separate process steps are required, each process step increasing the cost of the process.
Aufgabe der Erfindung ist es, ein Verfahren der eingangs genannten Art so auszubilden, daß der erforderliche Bindemittelanteil verringert sowie die Anzahl der benötigten Verfahrensschritte reduziert werden kann.The object of the invention is to develop a method of the type mentioned in such a way that the required proportion of binder can be reduced and the number of required process steps can be reduced.
Ausgehend von einem Verfahren der eingangs genannten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Teilchen zunächst in einem einzigen Verfahrensschritt zerkleinert, in einem darauffolgenden Verfahrensschritt erhitzt und in einem sich daran anschließenden Verfahrensschritt nachzerkleinert werden und daß die nachzerkleinerten Teilchen schließlich mit Bindemittel versetzt werden.Starting from a process of the type mentioned at the outset, this object is achieved according to the invention in that the particles are first comminuted in a single process step, heated in a subsequent process step and subsequently comminuted in a subsequent process step, and finally the binder is added to the subsequently comminuted particles.
Es hat sich überraschenderweise herausgestellt, daß zum einen auf einen separaten, dem ersten Zerkleinerungsprozeß nachgeschalteten Verfahrensschritt zum Aufschließen der zerkleinerten Teilchen verzichtet werden kann, wenn erfindungsgemäß die zerkleinerten Teilchen unmittelbar zu- nächst erhitzt, danach nachzerkleinert und erst dann mit Bindemittel versetzt werden. Zum anderen kann bei dieser Vorgehensweise die Menge des benötigten Bindemittels gegenüber dem bekannten Verfahren reduziert werden, ohne daß die Festigkeitseigenschaften der erzeugten Platten verschlechtert werden.It has surprisingly been found that, on the one hand, a separate process step downstream of the first comminution process for disintegrating the comminuted particles can be dispensed with if, according to the invention, the comminuted particles are first heated, then comminuted and only then are binders added. On the other hand, this procedure can reduce the amount of binder required compared to the known method without deteriorating the strength properties of the plates produced.
Das erfindungsgemäße Verfahren ist somit einfacher und kostengünstiger durchzuführen als das Verfahren der eingangs genannten Art, da sowohl ein separater Verfahrensschritt eingespart als auch der benötigte Bindemittelanteil reduziert werden kann. Während bei dem Verfahren der eingangs genannten Art die erforderliche Dosierung des Bindemittels mit 6 % Festharz/ atro Stroh angegeben ist, ist bei dem erfindungsgemäßen Ver- fahren eine Dosierung von ca. 4,5 % ausreichend.The method according to the invention is thus easier and less expensive to carry out than the method of the type mentioned at the outset, since both a separate method step can be saved and the required proportion of binder can be reduced. While the required dosage of the binder is given with 6% solid resin / dry straw in the method of the type mentioned at the outset, a dosage of about 4.5% is sufficient in the method according to the invention.
Nach einer vorteilhaften Ausführungsform der Erfindung werden die zerkleinerten Teilchen angeröstet, das heißt so lange und/ oder auf eine solche Temperatur erhitzt, daß sie insbesondere an ihrer Oberfläche eine be- stimmte spröde Porosität erhalten, insbesondere daß Risse an der Oberfläche der Teilchen entstehen. Aufgrund der durch die erfindungsgemäße Erhitzung entstehenden spröden Porosität der Teilchen splittert die an der Oberfläche der Teilchen vorhandene Wachsschicht bei dem sich an den Erhitzungsvorgang anschließenden Nachzerkleinerungsvorgang ab, wo- durch zwei positive Effekte erzielt werden. Zum einem kann auf die Zugabe einer separaten Paraffinemulsion verzichtet werden, da die abgesplitterten Wachsteilchen deren Funktion übernehmen. Zum anderen wird das nach dem Nachzerkleinern zugegebene Bindemittel von der nun von der Wachsschicht befreiten Oberfläche der Teilchen besser aufgenommen, so daß insgesamt weniger Bindemittel zugegeben werden muß. Im folgenden werden typische Herstellungs- und Qualitätskennziffern an Hand eines bevorzugten Ausführungsbeispiels des erfindungsgemäßen Herstellungsverfahrens angegeben:According to an advantageous embodiment of the invention, the comminuted particles are roasted, that is to say heated and / or heated to such a temperature that they acquire a certain brittle porosity, in particular on their surface, in particular that cracks form on the surface of the particles. Due to the brittle porosity of the particles resulting from the heating according to the invention, the wax layer present on the surface of the particles splinters off during the post-comminution process following the heating process, whereby two positive effects are achieved. On the one hand, there is no need to add a separate paraffin emulsion, since the chipped wax particles take on their function. On the other hand, the binder added after the secondary comminution is better absorbed by the surface of the particles now freed from the wax layer, so that less binder has to be added overall. Typical manufacturing and quality indicators are given below on the basis of a preferred exemplary embodiment of the manufacturing method according to the invention:
Die Eingangsteilchen werden beispielsweise mit einem Eingangsfeuchtigkeitsgehalt von ca. 15 % in einen Häcksler gegeben und dort in einem einzigen Verfahrensschritt zerkleinert. Die zerkleinerten Teilchen werden anschließend erhitzt und dabei soweit getrocknet, daß sie noch einen Feuchtigkeitsgehalt von ca. 2 - 3 Gew.-% besitzen.The input particles are, for example, placed in a chopper with an input moisture content of approx. 15% and comminuted there in a single process step. The crushed particles are then heated and dried to the extent that they still have a moisture content of about 2-3% by weight.
Durch das Erhitzen erfolgt ein Anrösten der zerkleinerten Teilchen, wodurch insbesondere die Oberfläche der Teilchen eine spröde Porosität erhält, die sich beispielsweise in unregelmäßig angeordneten Rissen an der Oberfläche der Teilchen darstellt.The comminuted particles are roasted by heating, which in particular gives the surface of the particles a brittle porosity, which is manifested, for example, in irregularly arranged cracks on the surface of the particles.
In einem nächsten Verfahrensschritt werden die angerösteten Teilchen nachzerkleinert, wodurch die an der Oberfläche vorhandene Wachsschicht absplittert und die Splitter mit den nachzerkleinerten Teilchen vermischt werden. Die nachzerkleinerten, unfraktionierten Teilchen werden mit Bin- demittel in einer Höhe von ca. 4,5 %/atro Stroh versetzt, so daß eine Be- leimungsfeuchte von ca. 4 Gew.-% erzielt wird.In a next process step, the roasted particles are comminuted, causing the wax layer on the surface to chip off and the splinters to be mixed with the comminuted particles. The post-shredded, unfractionated particles are mixed with binding agent at a height of approx. 4.5% / dry straw, so that a sizing moisture of approx. 4% by weight is achieved.
Die beleimten Teilchen werden mit geeigneten Streuverfahren zu einem Vlies gestreut und beispielsweise bei 200 °C unter einem Preßdruck von maximal 3,5 N/mm2 für einen Preßzeitfaktor von beispielsweise 11,5 Sekunden pro Millimeter Dicke des Vlieses zu dem gewünschten Formkörper verpreßt. Bei einer Dicke des Vlieses von ca. 19 mm ergibt sich somit eine Preßzeit von ca. 3,6 Minuten. Typische Qualitätskennziffern einer nach dem erfindungsgemäßen Verfahren hergestellten Platte sind:The glued particles are scattered to a nonwoven using suitable scattering methods and, for example, at 200 ° C. under a pressure of maximum 3.5 N / mm 2 for a pressing time factor of, for example, 11.5 seconds per millimeter thickness of the nonwoven to the desired shaped body. With a thickness of the fleece of approx. 19 mm, this results in a pressing time of approx. 3.6 minutes. Typical quality indicators of a plate produced by the process according to the invention are:
Plattendicke 19 mm Rohdichte 640 kg/m3 Biegefestigkeit 16 N/mm2 Querzugfestigkeit 0,57 N/mm2 2 Std. Quellung 3,2 % 24 Std.
