Die Verarbeitung von thermoplastischen Kunststoffen erfolgt in der Regel in der Schmelze. Die dabei ein¬ tretenden Struktur- und Zustandsänderungen führen da- zu, dass es häufig zu einer Änderung der chemischenThe processing of thermoplastics usually takes place in the melt. The structural and state changes occurring in this case lead to the fact that there is frequently a change in the chemical
Struktur des Grundstoffes kommt. Vernetzung, Oxidati- on, Molekulargewichtsänderung und damit auch Änderun¬ gen der physikalischen und technischen Eigenschaften können so die Folge sein. Um die Belastung der PoIy- mere während der Verarbeitung zu reduzieren, setzt man je nach Kunststoff unterschiedliche Additive ein. Im Allgemeinen werden dabei Stabilisatoren zugesetzt, die die Veränderungsprozesse, wie Vernetzungs- oder Abbaureaktion, unterbinden oder zumindest bremsen. Weiterhin werden den meisten Kunststoffen Gleitmittel beigemengt, die primär die Aufgabe haben, das Flie߬ verhalten der Schmelze zu verbessern.Structure of the base material comes. Crosslinking, oxidation, changes in the molecular weight and thus also changes in the physical and technical properties can thus be the result. In order to reduce the load on the polymers during processing, different additives are used, depending on the plastic. In general, stabilizers are added which suppress or at least slow down the processes of change, such as crosslinking or degradation reaction. Furthermore, lubricants are added to most plastics, which primarily have the task of improving the flow behavior of the melt.
Bei der Verarbeitung von Kunststoffen werden in der Regel eine Vielzahl unterschiedlicher Additive gleichzeitig eingesetzt, von denen jedes für sich be¬ stimmte Aufgaben übernimmt. So werden Antioxidantien
und Stabilisatoren eingesetzt, damit eine chemische Schädigung des Kunststoffs bei der Verarbeitung ver¬ hindert werden kann und anschließend der Kunststoff gegen Umgebungseinflüsse wie Hitze, UV-Licht, Witte- rung und Sauerstoff lange Zeit stabil ist. Gleitmit¬ tel hingegen führen zu einer Verbesserung des Flie߬ verhaltens und verhindern ein zu starkes Kleben der Kunststoffschmelze an heißen Maschinenteilen. Ebenso wirken sie als Dispergiermittel für Pigmente, Füll- und Verstärkungsstoffe.In the processing of plastics, a large number of different additives are generally used at the same time, each of which assumes specific tasks for itself. That's how antioxidants work and stabilizers used so that a chemical damage to the plastic during processing ver¬ can be prevented and then the plastic against environmental influences such as heat, UV light, Witte- tion and oxygen for a long time stable. On the other hand, lubricants lead to an improvement in the flow behavior and prevent excessive adhesion of the plastic melt to hot machine parts. They also act as dispersants for pigments, fillers and reinforcing agents.
Die Verwendung von Flammschutzmitteln kann die Stabi¬ lität des Kunststoffs bei der Verarbeitung in der Schmelze beeinflussen. Flammschutzmittel werden häu- fig in hohen Dosierungen zugesetzt, um einen ausrei¬ chenden Flammschutz des Kunststoffs nach internatio¬ nalen Normen sicherzustellen. Aufgrund der chemischen Reaktivität, die für die Flammschutzwirkung bei hohen Temperaturen erforderlich ist, können Flammschutzmit- tel die Verarbeitungsstabilität von Kunststoffen be¬ einträchtigen. So kann es beispielsweise zu verstärk¬ tem Polymerabbau, zu Vernetzungsreaktion, zur Ausga¬ sung oder zu Verfärbungen kommen. Diese Effekte tre¬ ten hingegen bei einer Kunststoffverarbeitung ohne Flammschutzmittel eventuell gar nicht oder nur in ab¬ geschwächter Form auf.The use of flame retardants can influence the stability of the plastic during melt processing. Flame retardants are frequently added in high dosages in order to ensure sufficient flame retardancy of the plastic according to international standards. Due to the chemical reactivity required for the flameproofing effect at high temperatures, flame retardants can impair the processing stability of plastics. Thus, for example, increased polymer degradation, crosslinking reaction, emanation or discoloration may occur. On the other hand, these effects may not occur at all or only in a weakened form in the case of plastics processing without flame retardants.
Insbesondere für thermoplastische Polymere haben sich die Salze von Phosphinsäuren, d.h. Phosphinate, als wirksame, flammhemmende Zusätze erwiesen. So sind in der EP 0 699 708 Calcium- und Aluminiumphosphinate in Polyestern als besonders wirksam beschrieben worden,
wobei diese die Materialeigenschaften der Polymermas¬ sen weniger als z.B. die Alkalimetallsalze beein¬ trächtigen.In particular, for thermoplastic polymers, the salts of phosphinic acids, ie phosphinates, have proven to be effective, flame-retardant additives. Thus, EP 0 699 708 has described calcium and aluminum phosphinates in polyesters as being particularly effective, These impair the material properties of the polymer compositions less than, for example, the alkali metal salts.
