Description
Geruchsneutralisierende Zusammensetzuna Odor neutralizing composition
Die vorliegende Erfindung betrifft eine Zusammensetzung enthaltend einen Ge- ruchsneutralisierer, ein Verfahren zu der Zusammensetzung und die Verwen dung des Geruchsneutralisierers. The present invention relates to a composition containing an odor neutralizer, a method for the composition and the use of the odor neutralizer.
Geruch ist neben der Haptik ein wesentlicher Faktor für den Erfolg von Konsum produkten. Riecht ein Werkstoff oder Bauteil aus Kunststoff, beispielsweise im Innenraum eines Kraftfahrzeugs, subjektiv unangenehm, kann das die Kaufent scheidung negativ beeinflussen. Für zahlreiche Kunststoffprodukte gelten zu dem strenge Vorgaben hinsichtlich der Emission von chemischen Stoffen. Es liegt daher im Interesse von Kunststoffverarbeitern und Compoundeuren, Ge ruchsemissionen von Kunststoffen bestmöglich zu reduzieren. In addition to haptics, smell is a key factor in the success of consumer products. If a material or component made of plastic, for example in the interior of a motor vehicle, smells subjectively unpleasant, this can have a negative impact on the purchase decision. For many plastic products there are also strict requirements regarding the emission of chemical substances. It is therefore in the interests of plastics processors and compounders to reduce odor emissions from plastics as much as possible.
Die Ursachen für das Auftreten von Gerüchen sind vielfältig. Häufig ist nicht der Kunststoff selbst für den Geruch verantwortlich, sondern Restmengen an nie dermolekularen Stoffen, die aus der Herstellung des Kunststoffs Zurückbleiben. Auch Additive, wie z.B. Verarbeitungshilfsmittel, Stabilisatoren, Fasern oder Füllstoffe, die bei der Herstellung eines Werkstoffs dem Kunststoff beigemischt werden, können störende Gerüche verursachen. Darüber hinaus entstehen auch bei der Herstellung und Weiterverarbeitung von Kunststoff-haltigen Werkstof fen, z.B. infolge von thermischer Zersetzung, Stoffe, die zu Störgerüchen führen können. There are many reasons why odors occur. It is often not the plastic itself that is responsible for the smell, but residual amounts of low-molecular substances that remain from the manufacture of the plastic. Additives such as processing aids, stabilizers, fibers or fillers that are added to the plastic during the manufacture of a material can also cause unpleasant odours. In addition, during the manufacture and further processing of materials containing plastic, e.g. as a result of thermal decomposition, substances are produced which can lead to unpleasant odours.
Das Risiko von Geruchsemissionen wird noch verstärkt, wenn als Ausgangsma terial nicht Kunststoff-Neuware sondern Rezyklat oder eine Mischung aus Neu ware und Rezyklat verwendet wird. Kunststoffrezyklate aus Post-Consumer-Ab- fällen enthalten Geruchsstoffe, die sich bei der Aufbereitung häufig nicht voll ständig entfernen lassen. Bei Verpackungsabfällen handelt es sich oftmals um typische Stoffwechsel Produkte von Mikroorganismen, die einen käseartigen und fäkalen Geruch generieren.
An Versuchen, den Geruch von Kunststoffteilen zu reduzieren, hat es nicht ge mangelt. So beschreibt beispielsweise WO 2017/060171 die Verwendung eines anorganischen Additivs, insbesondere eines Silikatmaterials. Diatomeenerde und Calciumsilikate sind ausdrücklich genannt. The risk of odor emissions is increased if the starting material is not new plastic but recycled material or a mixture of new material and recycled material. Plastic recyclates from post-consumer waste contain odors that often cannot be completely removed during processing. Packaging waste is often a typical product of the metabolism of microorganisms that generate a cheesy and fecal odour. There has been no shortage of attempts to reduce the smell of plastic parts. For example, WO 2017/060171 describes the use of an inorganic additive, in particular a silicate material. Diatomaceous earth and calcium silicates are expressly mentioned.
Es besteht weiterhin Bedarf nach alternativen Möglichkeiten zur Reduktion von Gerüchen in Kunststoffen, die möglichst in einigen Aspekten den bekannten Al ternativen überlegen sind. There is still a need for alternative ways of reducing odors in plastics which, if possible, are superior to the known alternatives in some aspects.

'Sortenähnliche' Kunststoffe stimmen bei der Aufbereitung in ihren Grundpoly meren überein, weichen aber von den Eigenschaften (z.B. flammhemmende Zu sätze) voneinander ab.

'Mixed' means that different plastics with chemical compatibility are processed. They are only compatible if they can be homogeneously mixed with one another during the melting process and can be processed into a molding material with satisfactory mechanical properties and an acceptable surface.
'Verunreinigt' bedeutet, dass die aufzubereitenden Kunststoffe andere Stoffe enthalten, die die Eigenschaften eines daraus herzustellenden Formteils beein trächtigen.
