Description
Füllstoff für Kunststoffe und Kunstharzmassen Es ist bekannt, bei der Herstellung von Kunststoffen und Kunstharzmassen, z. B. aus Polyvinylverbindungen, härtbaren Kunstharzen oder Caseinmassen (Kunsthorn), die nach dem Gieß- oder beliebigen Preßverfahren, z. B. durch Verpressen, Verwalzen oder Verspritzen, in Formkörper übergeführt werden, als Füllstoffe neben pulvrigen oder körnigen Füllstoffen, wie Holzmehl, Schiefermehl, Talkum, u. dgl., auch faserige Füllstoffe, wie z. B;. Cellulosefasern oder Asbestfasern, zu verwenden.Filler for plastics and synthetic resin compounds It is known at the production of plastics and synthetic resin compounds, e.g. B. made of polyvinyl compounds, hardenable synthetic resins or casein masses (artificial horn), which after casting or any Pressing process, e.g. B. by pressing, rolling or spraying, in moldings be transferred as fillers in addition to powdery or granular fillers, such as Wood flour, slate flour, talc, and the like, also fibrous fillers, such as. B ;. Cellulose fibers or asbestos fibers.
Es wurde nun gefunden, daß als Füllstoff für Kunststoffe und Kunstharzmassen der vorstehend bezeichneten Art mit besonderem Vorteil zerfaserte Xylite angewandt werden. Xylite sind holzige Stoffe, die tertiären Waldungen entstammen und unter Tage in Braunkohlenflözen und Mooren in riesigen Mengen vorkommen. Dieser bisher noch nicht angewandte Füllstoff zeichnet sich durch besonders große Billigkeit aus, und seine Anwendung führt zur Herstellung von besonders widerstandsfesten Werkstoffen. Ein weiterer bedeutsamer Vorteil besteht darin, daß dieser Füllstoff im Gegensatz zu rezentem Holz bzw. daraus gewonnenem Holzmehl oder Holzschliff nicht ,durch Feuchtigkeit zu quellen "oder beim Trocknen zu schrumpfen vermag, wodurch dieser Füllstoff vielseitiger und besser verwendbar ist als Füllstoffe auf der Grundlage von rezentem Holz. So zeichnen sich die unter Verwendung von Xylitfasern als Füllstoff hergestellten Formkörper durch besonders hohe Maßbeständigkeit aus. Diese vorteilhafte Wirkung ist darauf zurückzuführen, daß das in den Xyliten enthaltene Harz durch die lange Lagerung unter Tage inaktiv geworden ist, wodurch es sein Schrumpfungs-und Quellungsvermögen verloren hat. Die Füllstoffe können in üblicher Weise, z. B. durch Zugabe zu einer Lösung, Emulsion oder Dispersion. der Kunstharze oder durch Einwalzen in die festen Kunstharze mittels heißer Walzen, gegebenenfalls unter Zusatz von Farb- oder anderen Füll- und Zusatzstoffen, mit den Kunstharzen zu homogenen Produkten verarbeitet werden. Dic Beimengung der Füllstoffe kann aber auch in an sich bekannter Weise in einem Knetapparat unter Verwendung leicht flüchtiger L5sungsmittel erfolgen, welche nach erzielter Homogenisierung durch Verdampfen wieder entfernt werden.It has now been found that as a filler for plastics and synthetic resin compositions of the type described above are used with particular advantage in fiberized xylites will. Xylites are woody substances that come from tertiary forests and under Days in lignite seams and bogs occur in huge quantities. This one so far filler that has not yet been applied is characterized by particularly great cheapness, and its application leads to the production of particularly resistant materials. Another significant advantage is that this filler is in contrast not to recent wood or wood flour or wood pulp obtained from it, due to moisture is able to swell "or to shrink on drying, which makes this filler more versatile and is more useful as fillers based on recent wood. So the moldings produced using xylitol fibers as filler are distinguished characterized by particularly high dimensional stability. This beneficial effect is on it attributed to the fact that the resin contained in the xylites due to the long storage underground has become inactive, which makes it shrink and swell has lost. The fillers can be used in a conventional manner, for. B. by Addition to a solution, emulsion or dispersion. synthetic resins or by rolling in into the solid synthetic resins by means of hot rollers, optionally with the addition of Dyes or other fillers and additives, with the synthetic resins to form homogeneous products are processed. The addition of the fillers can, however, also be known per se Can be done in a kneading machine using highly volatile solvents, which are removed again by evaporation after homogenization has been achieved.
