Description

Formteile mit verbesserten Oberflächen Moldings with improved surfaces
Polycarbonate gehören zur Gruppe der technischen Thermoplaste. Technische Termoplaste finden vielseitige Anwendungen im Elektro- und Elektronikbereich, als Gehäusewerkstoff von Leuchten und bei Anwendungen, bei denen besondere mechanische Eigenschaften gefordert sind. Bei diesen An- Wendungen werden fast immer die guten thermischen und mechanischen Eigenschaften wie Vicat- Temperatur, Glastemperatur und Schlagzähigkeit benötigt. Dabei werden u. a. Ruße für dunkle oder opake Einfärbung eingesetzt. Ein Nachteil derartiger Zusammensetzungen besteht häufig in der glänzenden Oberfläche der daraus gefertigten Gegenstände/Formteile. Um diesen Nachteil zu verhindern müssen die Werkzeugoberflächen aufgeraut werdenPolycarbonates belong to the group of engineering thermoplastics. Technical thermoplastics find versatile applications in the electrical and electronics sector, as housing material of luminaires and in applications where special mechanical properties are required. These applications almost always require good thermal and mechanical properties such as Vicat temperature, glass transition temperature and impact strength. This u. a. Blacks used for dark or opaque coloring. A disadvantage of such compositions is often the shiny surface of the articles / moldings made therefrom. To prevent this disadvantage, the tool surfaces must be roughened
Es bestand daher die Aufgabe, Formteile bereitzustellen, die die oben genannten Nachteile nicht aufweisen.It was therefore an object to provide moldings that do not have the disadvantages mentioned above.
Es wurde gefunden, dass Formteile aus Thermoplasten und Multi Wall Carbon Nanotubes (MWCNT) diese Nachteile nicht aufweisen.Thermoplastics and Multi Wall Carbon Nanotubes (MWCNT) have not been found to have these disadvantages.

Als Füllstoffe werden eine Vielzahl verschiedener Füllstoffe erwähnt, unter anderem werden auch sogenannte MWCNT (mulitwall carbon nano-tubes) erwähnt. Konkrete Beispiele enthaltend MWCNT werden nicht beschrieben.EP-A 1770126 describes polycarbonate compositions containing a fluorine-containing organic metal salt, at least one further component selected from the group consisting of a flame retardant, a fatty acid ester, a UV absorber, PTFE fibers, a filler, a silicate mineral and a titanium dioxide pigment. As fillers a variety of different fillers are mentioned, among others, so-called MWCNT (mulitwall carbon nanotubes) are mentioned. Concrete examples containing MWCNT are not described.
