Abstract

Filler comprises powdered aerogel and 25-50, esp. 32-35% talc.

Description

Büllstoffkombination für Duroplaste Die Erfindung betrifft eine Füllstoffkombination zur Zugabe zu Duroplasten, insbesondere zu Polyesterharzen, vernetzenden Polyurethanen und Äthoxylinharzen. Combination of fillers for thermosetting plastics The invention relates to a combination of fillers for addition to thermosets, especially polyester resins, crosslinking polyurethanes and ethoxylin resins.

Während es bekannt war, pulverförmige mineralische Substanzen, wie Quarzmehl, duroplastischen Kunststoffen zuzusetzen, um einerseits deren Härte zu erhöhen und andererseits Ersparnisse zu erzielen, war es bisher nicht möglich, trotz eines hohen Füllstoffgehaltes eine ausreichende Zähigkeit zu erzielen; vielmehr erhöhte sich bei Erhöhung des Fülllstoffgehaltes durchweg auch die Sprödigkeit des gefüllten Kunststoffes.While it was known, like powdered mineral substances Quartz powder, to add thermosetting plastics to their hardness on the one hand increase and on the other hand savings to achieve, it was so far not possible to achieve sufficient toughness despite a high filler content achieve; on the contrary, it also increased consistently with an increase in the filler content the brittleness of the filled plastic.

Der Erfindung liegt die Aufgabe zugrunde, eine Füllstoffkombination zu schaffen, mit der dem damit gefüllten Duroplasten wahlweise eine höhere Härte oder eine höhere Zähigkeit verliehen wird.The invention is based on the object of a filler combination to create, with the thermosetting plastic filled with it, optionally a higher hardness or a higher toughness is given.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Füllstoffkombination aus pulverförmigem Aeerogel und einem Zusatz von 25 bis 50 Gew.-% Talkum enthält.The object is achieved according to the invention in that the filler combination from powdered airgel and an addition of 25 to 50 wt .-% talc.

Je nach Höhe des Anteils an Talkum wird, auch bei hohen Füllstoffmengen, eine größere oder kleinere Sprödigkeit bzw. umgekehrt eine kleinere oder größere Zähigkeit und Schlagfestigkeit erreicht.Depending on the amount of talc, even with high amounts of filler, greater or lesser brittleness or, conversely, lesser or greater Toughness and impact resistance achieved.

Je nach den besonderen Verhältnissen kann eine solche Füllstoffkombination in einer Gesamtmenge von zwischen 10 und 80 % dem Harz beigefügt werden.Depending on the particular circumstances, such a combination of fillers can be used be added to the resin in a total amount of between 10 and 80%.

Vorzugsweise ist vorgesehen, daß der Anteil an Talkum zwischen 32 und 35 Gew.-% liegt. Dadurch wird eine für die üblichen Zwecke des Maschinenbaues optimale Festigkeit erzielt.It is preferably provided that the proportion of talc is between 32 and 35 wt%. This is one for the usual purposes of mechanical engineering achieved optimal strength.

Aus einem mit einer solchen Füllstoffkombination gefüllten Polyesterharz wurden Flansche und Bördelringe hergestellte, die allen an sie gestellten Anforderungen bestens geneigten.Made from a polyester resin filled with such a filler combination Flanges and crimp rings were manufactured to meet all of the requirements placed on them best inclined.

Selbstverständlich kann ein mit einer derartigen Füllstoffkombination gefüllter Kunststoff in der bekannten Weise zusätzlich durch Zugabe von Glasfasern verstärkt werden, wobei man dann im allgemeinen einen niederen Anteil an Füllstoff wählt.Of course, one with such a filler combination can be used filled plastic in the known manner additionally by adding glass fibers be reinforced, in which case one then generally has a low proportion of filler chooses.

Die Erfindung wird nachstehend an einem Beispiel näher erläutert: zu einer Menge von 72 Gew.-% Polyester wurde eine Gemenge aus 14 % pulverförmigem Aerogel und 11 % pulverförmigem Talkum gegeben, sorgfältig in dem Kunstharz verteilt und sodann 0,5 96 eines Beschleunigers und 2,6 96 eines Härters zugegeben.The invention is explained in more detail below using an example: a mixture of 14% powdered polyester became an amount of 72% by weight polyester Airgel and 11% powdered talc, carefully distributed in the synthetic resin and then 0.596 of an accelerator and 2.696 of a hardener were added.

Das Gemenge wurde in Formen gegeben und Flansche und Bördelringe für den Rohrleitungsbau daraus hergestellt.The mixture was poured into molds and flanged and flared rings for the pipeline construction made from it.

Bei einem anderen Beispiel wurde in gleicher Zusammensetzung anstelle des Polyesterharzes ein Epoxydharz verwendet und zusätzlich noch Glasfasern in das mit der Füllstoffkombination hergestellte Gemenge eingebracht.In another example, the same composition was used instead of the polyester resin, an epoxy resin is used and glass fibers are also added to the with the filler combination produced mixture introduced.
