Description

Verfahren zur Herstellung von Kunstholz aus pflanzlichem Material Das Hauptpatent betrifft ein Verfahren zur Herstellung von Kunstholz durch Verpressen von pflanzlichem Material. Das Verfahren ist dadurch gekennzeichnet, daß man lufttrockene faserhaltige Pflanzenstoffe mit härtbaren oder vulkanisierbaren Bindemitteln überzieht und unter paralleler Lagerung der Fasern bei erhöhter Temperatur in der Weise preßt, daß unter Härtung bzw. Vulkanisation des Bindemittels eine dauernde Volumenveränderung der Faserstoffe und eine Vereinigung zu Preßkörpern, nicht aber eine völlige Durchtränkung der Faserstoffe mit dem Harz erreicht wird.Process for the production of artificial wood from vegetable material The main patent relates to a method for producing synthetic wood by pressing of vegetable matter. The process is characterized in that air-dry coated fibrous plant materials with hardenable or vulcanizable binders and presses with parallel storage of the fibers at an elevated temperature in such a way that that with hardening or vulcanization of the binder a permanent change in volume of the fibrous materials and a union to form pressed bodies, but not a complete impregnation the fiber is reached with the resin.

Die vorliegende Erfindung betrifft eine Verbesserung des Verfahrens des Hauptpatents, derart, daß die Breite der verwendeten Pflanzenstränge, bei denen der natürliche Zusammenhang der Fasern nicht zerstört ist, der Breite der anzufertigenden Preßstücke entspricht. Wie aus der Beschreibung des Hauptpatents ersichtlich ist, kann zweckmäßig auch in Streifen von beliebiger Dicke und Breite zerteiltes Holzmaterial die Rolle der Pflanzenmaterialstränge vertreten. In diesem Falle ist die Verarbeitung besonders einfach, wenn die Breite des Holzmaterials gleich der Breite der zu erzeugenden Stücke ist. Wenn das erzeugte Stück die Gestalt einer Plätte oder eines Brettes hat, wird man als Holzmaterial zweckmäßig Holzfurnier von gewünschter Dicke wählen. Solche Holzfurniere können leicht hergestellt und mit Harz bestrichen werden und auch beim Trocknen sowie Beschicken der Presse bequem gehandhabt werden. Besonders wertvoll ist in diesem Falle, daß sich das Material sehr leicht in gleichmäßiger Schicht unter die Presse bringen läßt.The present invention relates to an improvement in the method of the main patent, such that the width of the plant strands used, in which the natural cohesion of the fibers is not destroyed, the width of the fabric to be made Press pieces corresponds. As can be seen from the description of the main patent, can expediently also cut wood material into strips of any thickness and width represent the role of the plant material strands. In this case, the processing is especially easy if the width of the wood material is equal to the width of the one to be produced Pieces is. If the piece produced has the shape of a plate or a board wood veneer of the desired thickness is expediently chosen as the wood material. Such wood veneers can be easily made and coated with resin and can also be conveniently handled when drying and loading the press. Particularly What is valuable in this case is that the material very easily becomes more uniform Bring layer under the press.

Arbeitet man nach den Vorschriften des Hauptpatents, so erzielt man in allen Fällen eine vorzügliche, feste Verleimung. Dazu kommt, daß, wenn auch die Bindung zwischen Holz und Harz sehr gut ist, das Holz andere Festigkeitswerte aufweist und daß es vor allem weniger spröde -ist. Dadurch ist es erklärlich, daß ein Kunstholzbrett, welches aus Furnierholzlagen gleicher Breite besteht, eine größere Biegefestigkeit in der Richtung quer zur Holzfaser und parallel zur Schichtung aufweist als ein z. B. aus Holzdraht gepreßtes Stück. Ganz besonders fällt dieses dann ins Gewicht, wenn das hergestellte. Stück ein dün .e'@: Brett darstellt, das eine möglichst große' Biegefestigkeit besitzen soll. In diesem kill bedeutet das vorliegende Verfahren nicht *ttr" eine Erleichterung der Herstellung, sondein eine wesentliche Verbesserung des hergestell:---ten Produktes.If you work according to the provisions of the main patent, you achieve in all cases an excellent, firm gluing. In addition, even if the The bond between wood and resin is very good, the wood has different strength values and above all that it is less brittle. This explains why a synthetic wood board, which consists of plywood layers of the same width, a greater flexural strength in the direction transverse to the wood fiber and parallel to the stratification as a z. B. piece pressed from wooden wire. This is especially true then weight if the manufactured. Piece a thin .e '@: board that represents should have the greatest possible flexural strength. In this kill that means The present process is not a * ttr "facilitation of manufacture, but rather one substantial improvement of the manufactured product.
