Description
Den Gegenstand vorliegender Erfindung bildetForms the subject of the present invention
ein Verfahren zur Herstellung von Stoffen, die als Ersatz für Weichgummi oder Leder dienen sollen. Als hauptsächliches Ausgangsmateriala process for the production of fabrics that serve as a substitute for soft rubber or leather should. As the main starting material
S dient Hefe.S serves yeast.
Die Erfinder haben bereits verschiedene Verfahren vorgeschlagen, um von der Hefe (Hefezellreste, Hefeplasma, Trockenhefe) ausgehend, durch deren Behandlung mit Formaldehyd undThe inventors have already proposed various methods to start from the yeast (yeast cell residues, yeast plasma, dry yeast), by treating them with formaldehyde and
to Pressen bei erhöhter Temperatur zu ebonitartigen
oder hornigen Massen zu gelangen. Als Zusatz können dabei Eiweißstoffe, Teere, Phenole
usw. benutzt werden.
Es wurde nun gefunden, daß man auf gleicher Grundlage zu weichgummi- oder lederartigen
Stoffen gelangen kann. Zu diesem Zweck werden die bekannten Verfahren so abgeändert,
daß· man den Mischungen, die durch Erhitzen und Pressen; in die künstlichen Massen umge-to press at elevated temperature to reach ebonite-like or horny masses. Protein substances, tars, phenols, etc. can be used as additives.
It has now been found that soft rubber or leather-like materials can be obtained on the same basis. For this purpose, the known processes are modified in such a way that: the mixtures obtained by heating and pressing ; in the artificial masses
ao wandelt werden, Stoffe zusetzt, die ein. Entweichen eines Teiles des Wassers für die. Dauer verhindern oder die den durch heiße Pressung entstehenden künstlichen Massen infolge ihrer physikalischen Eigenschaft eine unveränderliche Weichheit und Elastizität geben. Derartige Zusatzmittel sind z. B. Leim, Teer, Glyzerin, öle, Harze. Ein mit solchen Zusatzmitteln in entsprechender Menge gemischter Hefebrei wird 2. B. mit Formaldehyd in Gasform oder als Flüssigkeit am besten unter Erwärmung behandelt und dann, wie bei der Herstellung der hartgummiähnlichen Körper, durch heiße Pressung fertiggestellt.ao are changed, substances are added that a. Escape of part of the water for that. Prevent duration or give the artificial masses created by hot pressing an invariable softness and elasticity due to their physical properties. Such additives are, for. B. glue, tar, glycerine, oils, resins. A yeast pulp mixed with such additives in the appropriate amount is treated, for example, with formaldehyde in gaseous form or as a liquid, preferably with warming, and then, as in the production of hard rubber-like bodies, finished by hot pressing.
Man kann dabei im übrigen die verschiedenen Arbeitsweisen anwenden, wie sie auch für die Herstellung der ebonitartigen Körper vorgeschlagen sind. Insbesondere kann man die Gemische vor der Pressung durch Trocknung, Koagulation, Fällung von überschüssigem Wasser trennen. Das Wesentliche ist, daß dem Grundgemische, wie es für die Gewinnung hartgummiartiger Körper geeignet ist, die genannten Zusätze in solcher Menge zugesetzt werden, daß die heiß gepreßteMasse nach dem Erkalten nicht mehr hornig, sondern in biegsamer oder elastischer Form erstarrt.You can use the different ways of working, as they are for the Manufacture of the ebonite-like bodies are proposed. In particular, you can use the mixtures before pressing by drying, coagulation, precipitation of excess water separate. The essential thing is that the basic mixture, as it is for the extraction of hard rubber-like Body is suitable, the additives mentioned are added in such an amount that the hot-pressed mass after cooling is no longer horny, but more flexible or elastic Solidified form.
Der. Umstand, daß sich die genannten Massen sehr gut und festhaftend an Gewebsfasern einerseits wie an Metalle anderseits anlagern, ermöglicht es weiter, die mechanischen Eigenschaften der entstehenden Erzeugnisse dadurch zu verbessern, daß man die Massen mit Gewebsfasern, fertigen Geweben oder mit Metalldrähten, Metallgeweben usw. zusammenpreßt.Of the. The fact that the masses mentioned adhere very well and firmly to tissue fibers on the one hand how to attach to metals on the other hand, it further enables the mechanical properties to improve the resulting products by adding fabric fibers to the masses, finished fabrics or pressed together with metal wires, metal fabrics, etc.
Die Eigenschaften des erzielten Produktes, insbesondere seine Härte, hängen im wesentlichen von dem angewandten Druck ab. Je höher man den Druck wählt, desto mehr nähern sich die Produkte in ihren physikalischen Eigen- · schäften dem Leder. Je geringer man den Drück wählt, desto mehr ähneln die Massen den weichen ungefüllten Gummigegenständen. Wenn manThe properties of the obtained product, in particular its hardness, depend essentially on the pressure applied. Ever the higher you choose the pressure, the closer the products in their physical properties shafts of the leather. The lower you choose the pressure, the more the masses resemble the soft ones unfilled rubber objects. If
