Description
Die Erfindung bezieht sich auf ein Innenaustattungsteil für Verkehrsmittel, insbesondere Kraftfahrzeuge, welches aus einem tragenden, formerhalten- den Teil und einem die Sichtseite des**** Innenausstattungstei- les bildenden Dekorteil besteht, und b<5j.,·.· dem das tragende formerhaltende Teil aus einem mittels Ver.-J.. Stärkungseinlagen versteiften Kunststoffmaterial und das De·-»..* korteil aus einem Bezugsmaterial besteht. JJ!The invention relates to an interior fitting part for means of transport, in particular motor vehicles, which consists of a load-bearing, shape-retaining part and a decorative part forming the visible side of the interior fitting part, and in which the load-bearing, shape-retaining part consists of a plastic material stiffened by means of reinforcing inserts and the decorative part consists of a covering material.
Innenausstattungsteile von Verkehrsmitteln, insbesondere.· Kraftfahrzeugen, müssen in der Regel, d.h. abgesehen von kaufc oder gar nicht mit dem Benutzer oder Ladegut des Verkehrmittels in Berührung kommenden Teilen, wie beispielsweise der Dachhimmel, eine gewisse Mindestfestigkeit gegenüber mechanischer Beanspruchung, d.h. z.B. eine bestimmte Biege- und Zugfestigkeit, aufweisen. Zugleich ist aber für alle Innenausstattungsteile auch eine gewisse Formhaltigkeit gegenüber natürlichen. Einflüssen, wie Temperatur und Temperaturwechsel, z.B. eine innerhalb bestimmter Grenzen vorgegebene thermische Längenausdehnung, oder eine begrenzte Fechtigkeitsaufnahme und dergl. mehr erforderlich. Neben der Erfüllung solcher mechanischer Festigkeitsanforderungen wird an die Gestaltung von Innenausstatungsteilen von Verkehrsmitteln, insbesondere Kraftfahrzeugen aber auch die Anforderung eines möglichst geringen Gewichtes sowie der unmittelbaren Befestigung von bzw. der unmittelbaren Verbindung mit die Sichtseite des Innenausstattungsteiles bildenden Dekormaterialien, wie Folien aus ABS, ASA, TPO, PVC, PE,PP oder Pur oder aber natürlichen Dekormaterialien wie Leder, Stoff, Velours oder Teppich gestellt. Schließlich sollen Innenverkleidungsteile von Verkehrsmitteln auch noch ein Mindestmaß an schalldämme.nden Eigenschaften besitzen und zu alledem auch noch mit einem geringstmöglichen Aufwand in recyclingfreundlicher Weise herstellbar sein. Um eine größtmögliche Anzahl dieser an die Innenausstattungsteile insbesondere von Kraftfahrzeugen, gestellten Anforderungen zuInterior fittings for means of transport, particularly motor vehicles, must generally have a certain minimum strength against mechanical stress, e.g. a certain bending and tensile strength, apart from parts that come into contact with the user or load of the means of transport, such as the roof lining. At the same time, however, all interior fittings must also have a certain degree of shape retention against natural influences such as temperature and temperature changes, e.g. a thermal linear expansion within certain limits, or a limited absorption of moisture and the like. In addition to meeting such mechanical strength requirements, the design of interior fittings for means of transport, particularly motor vehicles, must also be as light as possible and be directly attached to or directly connected to decorative materials that form the visible side of the interior fitting, such as films made of ABS, ASA, TPO, PVC, PE, PP or Pur or natural decorative materials such as leather, fabric, velour or carpet. Finally, interior trim parts of vehicles should also have a minimum of soundproofing properties and, in addition, be manufactured in a recycling-friendly manner with the least possible effort. In order to meet the greatest possible number of these requirements for interior trim parts, especially for motor vehicles,

The materials known and proven as filler or reinforcing material, such as mineral or synthetic fibers, were used, whereby the mineral or synthetic fibers were usually inserted into the foam mold in the form of a fleece, occasionally also in the form of strands, before the foamable material was introduced.
Die Verwendung von Kunststoff-oder Mineralfasern, wie auch die Verwendung von Mineralmaterial überhaupt, als Füllstoff oder Verstärkungsmaterial ist zum einen aufwendig und zum anderen wenig recycling- bzw. abfallbeseitigungsfreundlich sowie schließlich auch mit einem sehr hohen Gewichtsanteil behaftet. Insbesondere bedingt die Verwendung eines aus mineralischem Fasermaterial bestehenden Verstärkungsmaterials auf der einen Seite eine Belastung des Arbeitsbereiches, insbesondere der Gesundheit der mit der Herstellung der Innenverkleidungsteile befassten Arbeiter und führt auf der anderen Seite, z.B. bei einer Verbrennung von Abfall, zu einem erhöhten Anfall von unerwünschter und nicht verwertbarer Schlacke. Hier ist vor allem auch in Betracht zu ziehen, daß im Rahmen einer Abfallverbrennung auch ein gewisser Anteil an Heizmaterial erforderlich ist, der bisher durch Zuführung von Erdöl bzw. Heizöl gestellt werden muß.The use of plastic or mineral fibers, as well as the use of mineral material in general, as a filler or reinforcing material is, on the one hand, expensive and, on the other hand, not very recycling- or waste-disposal-friendly, and, finally, also involves a very high weight share. In particular, the use of a reinforcing material made of mineral fibers, on the one hand, places a strain on the work area, especially on the health of the workers involved in the production of the interior trim parts, and on the other hand, e.g. when waste is incinerated, leads to an increased amount of undesirable and non-recyclable slag. It must also be taken into account here that a certain amount of heating material is also required in the context of waste incineration, which has previously had to be provided by adding crude oil or heating oil.
Der Erfindung liegt daher die Ausfgabe zugrunde ein Innenverkleidungsteil für Verkehrsmittel, insbesondere Kraftfahrzeuge,The invention is therefore based on the object of an interior trim part for means of transport, in particular motor vehicles,

Diese Aufgabe wird erfindungsgemäß im Wesentlichen dadurch gelöst, daß das tragende, formerhaltende Teil aus einer geschäumten Zubereitung aus Polyäther-und/oder Polyesterpolyolen und höherwertigen aromatischen oder aliphatischen Isocyanaten bzw. einem geschäumten Gemisch aus natürlichen oder recycelten Polyolen und Isocyanten und einer Verstärkungseinlage aus natürlichen Fasern besteht, wobei der Anteil von Verstärkungsmaterial zwischen 10% und 90% beträgt.This object is essentially achieved according to the invention in that the load-bearing, shape-retaining part consists of a foamed preparation of polyether and/or polyester polyols and higher-quality aromatic or aliphatic isocyanates or a foamed mixture of natural or recycled polyols and isocyanates and a reinforcing insert made of natural fibers, the proportion of reinforcing material being between 10% and 90%.
Die Verwendung eines natürlichen Fasermaterials als Verstärkungsmaterial bzw. Füllstoff für ein aus nartürlichen oder recyelten Polyolen sowie einem Gemischanteil aus IsocyantAten bestehenden und geschäumtem Kunststoffanteil herzustellende Innenaustattungsteile für Verkehrsmittel, insbesondere Kraftfahrzeuge, ermöglicht unbeschadet der Erreichung der erforderlichen mechanischen und thermischen Eigenschaften des Innenverkleidungsteiles einerseits neben einer Senkung des Herstellungsaufwandes, da hierfür weitgehend recyceltes Material eingesetzt werden kann, und andererseits eine erhebliche Verringerung des Gewichtes des Innenverkleidungsteiles. Zusätzlich zu diesen Vorteilen gesellt sich auch noch der Effekt, daß aus natürlichem Fasermaterial bestehendes Verstärkungsmaterial bzw. Füllstoffmaterial zu einer allen auftretenden An-The use of a natural fiber material as a reinforcing material or filler for an interior trim part for means of transport, in particular motor vehicles, made of natural or recycled polyols and a mixture of isocyanates and foamed plastic, enables, without affecting the achievement of the required mechanical and thermal properties of the interior trim part, on the one hand, a reduction in production costs, since largely recycled material can be used for this, and on the other hand, a significant reduction in the weight of the interior trim part. In addition to these advantages, there is also the effect that reinforcing material or filler made of natural fiber material can be used to meet all requirements.

Ein ganz besonderer Vorteil der Verwendung natürlichen Fasermaterials ist ferner darin zu sehen, daß die mit der Verwendung z.B. von Glas-^ faser verbundene gesundheiltliche Belastung der Arbeiter be-·*"** seitigt ist. Darüberhinaus wird schließlich noch eine ent-'..·.· scheidende Verbesserung der Abfallbeseitigung, insbesondere,*.,requirements regarding temperature resistance and limited thermal expansion of the interior trim part in an optimal way. A very special advantage of using natural fiber material is that the health risks to workers associated with the use of glass fiber, for example, are eliminated. In addition, a decisive improvement in waste disposal is achieved, in particular,

Selbstverständlich kann im Rahmen der Erfindung auch die Verwendung von handelsüblichem PUR-Gemisch vorgesehen werden, falls natürliche oder recycelte Polyole, beispielsweise infolge ununzureichender Recyclingkapazitäten, nicht in ausreichender Menge zur Verfügung stehen.Of course, the use of commercially available PUR mixtures can also be provided within the scope of the invention if natural or recycled polyols are not available in sufficient quantities, for example due to insufficient recycling capacities.
Für die Verstärkungseinlage kann als völliger oder teilweiser Ersatz für Neumaterial auch recyceltes Material, wie in geeigneter Weise zerkleinertes Altpapier, gebrauchtes und gereinigtes Gewebe und dergl. verwendet werden.Recycled material, such as suitably shredded waste paper, used and cleaned fabric, etc., can also be used for the reinforcing insert as a complete or partial replacement for new material.
Für die Verstärkungseinlage werden als natürliches langfaseriges Material bevorzugterweise Jute-, Flachs-, Kokos-, Bananen-, Baumwolle-, Sisal-, Hanf-, oder Ramiefasern sowie Stroh verwendet, wobei dieses natürliche langfaserige Material oder natürliches langfaseriges Material überhaupt aus rezyklierten Gewebefetzen oder dergl. gewonnen werden kann.Jute, flax, coconut, banana, cotton, sisal, hemp or ramie fibers as well as straw are preferably used as natural long-fiber material for the reinforcement insert, whereby this natural long-fiber material or natural long-fiber material in general can be obtained from recycled fabric scraps or the like.
Als natürliches kurzfaseriges Material für die Verstärkungseinlage werden Papierschnitzel verwendet, die bevorzugterweise aus Altpapier oder aus industriellen Papierabfällen gewonnen werden.As a natural short-fiber material for the reinforcement insert, paper shreds are used, which are preferably obtained from waste paper or industrial paper waste.
