Description

Die Erfindung betrifft die Verwendung von recyclisiertem Polyvinyl-Butyral bei der Herstellung von Bodenbelägen.The invention relates to the use of recycled Polyvinyl butyral in the manufacture of floor coverings.

Kunststoff-Bodenbeläge, insbesondere solche aus PVC finden heute in großem Umfang Verwendung, vor allem wegen ihrer verschiedenartigen Oberflächengestaltung, ihrer weitgehenden Beständigkeit gegen Abnutzung und Wirtschaftlichkeit. Nachdem Polyvinylchlorid aufgrund der durch den Chlorgehalt schwierigen Entsorgung problematisch geworden ist, wurde versucht, durch Verwendung anderer, halogenfreier Werkstoffe, wie Polyacrylat, Polyurethan, Polyethylen/Polyvinylacetat-Copolymerisaten etc. Kunststoffbodenbeläge zu erzeugen, welche problemloser, z. B. durch Verbrennen, entsorgt werden können. Die entsprechenden Rohstoffe sind jedoch verglichen mit PVC, in der Herstellung und Verarbeitung teurer. Weiterhin bemüht man sich in letzter Zeit in zunehmendem Maße die Entsorgung der Kunststoffabfälle und der abgenutzten Fußbodenbeläge, die Verbrennung durch Recyclisierung so weit wie möglich zu vermeiden. Dies stößt jedoch auf Grenzen durch die Alterung der Materialien, durch Unverträglichkeit der durch unvollständige Sortierung zusammen­ kommenden Kunststoffkomponenten und Begleitstoffe, welche eine Recyclisierung verhindern, und letztlich dadurch, daß viele Bodenbeläge von Haus aus nicht wiederverwendbar sind.Find plastic floor coverings, especially those made of PVC used widely today, mainly because of their various surface designs, their extensive Resistance to wear and economy. After this Polyvinyl chloride due to the difficulty due to the chlorine content Trash disposal has been tried through Use of other, halogen-free materials, such as polyacrylate, Polyurethane, polyethylene / polyvinyl acetate copolymers etc. To produce plastic flooring, which more easily, for. B. by incineration. The corresponding However, compared to PVC, raw materials are in production and processing more expensive. Furthermore, one tries in the latter Time increasingly the disposal of plastic waste and the worn floor coverings that burn through Avoid recycling as much as possible. This comes across however, due to the aging of the materials Incompatibility related to incomplete sorting upcoming plastic components and accompanying substances, which one Prevent recycling, and ultimately that many Floor coverings are inherently not reusable.

Ein Abfallstoff, welcher in zunehmendem Maße anfällt, ist Poly­ vinyl-Butyral, welches in weichmacherhaltiger Form in großen Mengen als Zwischenschicht in Sicherheitsglas für Fenster in Gebäuden und Windschutzscheiben in Autos eingesetzt wird. Bei der Recyclisierung des Glasanteils werden diese Scheiben durch Zerstoßen und Mahlen in kleinere Glaspartikel zerlegt, die durch Sieben von den Kunststoffanteilen getrennt und als Roh­ glas wiederverwendet werden können. A waste material that is increasingly being generated is poly vinyl butyral, which in plasticized form in large Quantities as an intermediate layer in safety glass for windows in Buildings and windshields are used in cars. At The recycling of the glass portion causes these panes to go through Crush and grind into smaller glass particles that separated from the plastic parts by sieving and as raw glass can be reused.  

Die Kunststoffanteile, die bei diesem Verfahren in mehr oder weniger großen Stücken, verunreinigt durch Glassplitter, Me­ tallreste u. a. erhalten werden, werden bisher entweder ver­ brannt oder auf Deponien gebracht. Eine Wiederverwendung für den ursprünglichen Zweck als Sicherheitsglas ist nicht möglich, da die anhaftenden Verunreinigungen nicht wirtschaftlich abge­ trennt werden können. Eine Verwendung zur Herstellung von Bo­ denbelägen, bei denen die Verunreinigungen als Füllstoffe mit­ verarbeitet werden könnten, war bisher nicht möglich, da der große Anteil an Weichmachern (bis zu 50%) auch bei Zumischung größerer Mengen von Füllstoffen die Ausbildung eines beständi­ gen Belages verhindert.The plastic parts in this process in more or less large pieces, contaminated by broken glass, me tall remnants and. a. are obtained so far either ver burned or brought to landfill. Reuse for the original purpose as safety glass is not possible since the adhering impurities are not economically viable can be separated. A use for the production of Bo coverings in which the impurities are used as fillers could not be processed, because the large proportion of plasticizers (up to 50%) even when added Larger amounts of fillers form a constant prevented from covering.

Es stellte sich daher die Aufgabe, ein Verfahren zu finden, mit dem weichmacherhaltige PVB-Abfallstoffe recyclisiert, insbe­ sondere zu Bodenbelägen weiterverarbeitet werden können.The task therefore was to find a method with recycled the plasticized PVB waste, esp can be further processed especially for floor coverings.

In einer nicht vorpublizierten älteren Anmeldung wird vorge­ schlagen, recyclisiertes PVB, welches 5-50 Gew.% Weichmacher enthält, mit einer ausreichenden Menge weichmacherfreien, frisch hergestellten PVB und etwa gleichen Anteilen eines Füll­ stoffes zu verschneiden und aus dieser Masse Bodenbeläge zu formen. Bei der Nacharbeitung eines solchen Verfahrens zeigt sich, daß die so hergestellten Bodenbeläge relativ weich sind, so daß sie insbesondere bei Belastung, beispielsweise durch Möbel, nicht wieder zurückgehende Resteindrücke aufweisen. Darüber hinaus nimmt dieses Produkt relativ viel Wasser auf, was einerseits zu einer Verformung durch Feuchtigkeit (Schüsse­ lung) führt, und andererseits durch wäßrige oder wäßrig-alkoholische Substrate leicht Flecken verursacht werden.In an older application that has not been published, it is suggested beat, recycled PVB, which contains 5-50% by weight plasticizer contains, with a sufficient amount of plasticizer-free, freshly made PVB and about equal proportions of a filling to cut fabric and floor coverings from this mass to form. When reworking such a process shows that the floor coverings produced in this way are relatively soft, so that they are particularly under load, for example by Furniture, residual impressions that do not return. In addition, this product absorbs a relatively large amount of water, which on the one hand leads to deformation due to moisture (shots lung), and on the other hand by aqueous or aqueous-alcoholic Substrates can easily be stained.

Es stellte sich daher die zusätzliche Aufgabe, PVB so zu recy­ clisieren, daß die erhaltenen Produkte fester und wasserbe­ ständiger als PVB alleine sind. There was therefore the additional task of recycling PVB in this way clize that the products obtained are firmer and water resistant are more permanent than PVB alone.  

Überraschenderweise konnten diese beiden Aufgaben durch die im Hauptanspruch wiedergegebenen Merkmale gelöst und durch die in den Unteransprüchen angegebenen Merkmale gefördert werden.Surprisingly, these two tasks could be achieved through the Main claim reproduced features and solved by the in the features specified in the subclaims are promoted.

Es erscheint erstaunlich, daß durch die Beimischung von relativ geringen Mengen von Polyacrylat, worunter sowohl Suspensions- als auch Emulsionspolymerisate zu verstehen sind, sowohl die Wasserbeständigkeit als auch die Härte der erhaltenen Produkte gegenüber reinen Polyvinyl-Butyral-Kunststoffen wesentlich verbessert werden konnte, wodurch befriedigende Bodenbeläge hergestellt werden können, während andere Kunststoffe unge­ eignet sind. Beispielsweise führt das dem PVB wesentlich ähn­ lichere PVC zu einer Versprödung des Kunststoffgemisches, wenn es in einer zur Kompensierung des Weichmachers ausreichenden Menge zugesetzt wird.It seems astonishing that by adding relatively small amounts of polyacrylate, including both suspension and emulsion polymers are also to be understood, both the Water resistance as well as the hardness of the products obtained compared to pure polyvinyl butyral plastics Could be improved, creating satisfactory flooring can be made while other plastics are not are suitable. For example, this leads to the PVB essentially similar lighter PVC to embrittlement of the plastic mixture, if it is sufficient to compensate for the plasticizer Amount is added.

Die erfindungsgemäßen Fußbodenbeläge sollen die üblichen Anfor­ derungen wie Abrieb und Scheuerfestigkeit, Fleckenbeständig­ keit, Ausgewogenheit zwischen Härte und Flexibilität, leichte Herstellbarkeit und vorzugsweise geringe Kosten erfüllen.The floor coverings according to the invention are intended to meet the usual requirements changes such as abrasion and abrasion resistance, stain resistant balance, hardness and flexibility, light weight Feasibility and preferably low cost.

Die erfindungsgemäßen Bodenbeläge können als Einfachfolien oder auch Mehrschichtfolien, beispielsweise mit eingelegten Verstär­ kungsgeweben, Schaumschichten, farbigen Zwischenschichten und transparenten Oberflächenschichten, hergestellt werden.The floor coverings according to the invention can be used as single foils or also multilayer films, for example with inserted reinforcement tion fabrics, foam layers, colored intermediate layers and transparent surface layers.

Die erfindungsgemäßen Fußbodenbeläge bestehen beispielsweise aus 30-60% recyclisiertem PVB, welches 5-50, insbesondere etwa 30-50% Weichmacher enthält, 5-20% Polyacrylat, sowie 20-60% Füllstoffen. Darüber hinaus können in kleineren Mengen bekannte Zusatzstoffe, wie UV-Stabilisierungsmittel, Farbstoffe, Flammschutzmittel, antistatische Mittel, antibakte­ rielle Mittel usw., wie sie in üblichen Bodenbelägen auch enthalten sind, anwesend sein. Soweit die durch das PVB ein­ gebrachten Weichmacher eine ausreichende Flexibilität nicht gewährleisten, können zusätzliche Weichmacher in der benötigten Menge, beispielsweise bis zu 10%, zugesetzt werden. Als Weich­ macher werden beispielsweise Di-n-hexyladipat, Butylbenzyl­ phthalat oder Tetraethylenglykolheptanoat verwendet, die sowohl für PVB als auch für PA als Weichmacher geeignet sind.The floor coverings according to the invention exist, for example from 30-60% recycled PVB, which 5-50, in particular contains about 30-50% plasticizer, 5-20% polyacrylate, as well 20-60% fillers. In addition, in smaller Amounts of known additives, such as UV stabilizers, Dyes, flame retardants, antistatic agents, antibacterials rielle means, etc., as they are in conventional floor coverings are included to be present. So far the one by the PVB brought plasticizer not sufficient flexibility can guarantee additional plasticizers in the required  Amount, for example up to 10%, can be added. As soft Makers are, for example, di-n-hexyl adipate, butylbenzyl phthalate or tetraethylene glycol heptanoate used, both are suitable for both PVB and PA as plasticizers.

Die erfindungsgemäß verwendbaren Füllstoffe sind die in der Herstellung von PVC-Belägen üblichen anorganischen oder orga­ nischen Materialien. Ein Teil dieses Füllstoffes wird jedoch bereits durch die Glaspartikel, welche dem PVB-Recyclisat an­ haften, beigesteuert.The fillers which can be used according to the invention are those in Production of PVC coverings usual inorganic or orga African materials. Part of this filler, however, will already through the glass particles that the recycled PVB stick, contributed.

Die erfindungsgemäßen Produkte können auf üblichen Kalandern, wie sie für die Herstellung von Bodenbelägen aus PVC gebräuch­ lich sind, verarbeitet werden. Mehrfachschichten können durch Duplizieren und Triplizieren solcher Schichten unter Druck und Temperatur hergestellt oder durch Aufbringen und Angelieren von Plastisolschichten anderer Provenienz hergestellt werden. Letzteres Verfahren ist insbesondere sinnvoll, wenn Schaumiso­ lierschichten oder besondere Oberflächenkaschierungen aufge­ bracht werden sollen.The products according to the invention can on conventional calenders, as they are used for the production of PVC floor coverings are processed. Multiple layers can pass through Duplicate and triplicate such layers under pressure and Temperature or by applying and gelling Plastisol layers of other provenance are produced. The latter method is particularly useful if foam iso layers or special surface lamination should be brought.

In dem folgenden Beispiel ist eine typische Rezeptur, wie sie erfindungsgemäß hergestellt werden kann, mit einer ähnlichen Rezeptur, welche PVB-Recyclat zusammen mit frisch hergestelltem PVB enthält, und einer dritten Rezeptur, welche konventionelles PVC enthält, verglichen worden. Es zeigt sich, daß die erfin­ dungsgemäßen Bodenbeläge allen Erfordernissen genügen und so­ wohl reinen PVB-, als auch PVC-Bodenbelägen in vielen Belangen überlegen sind.The following example is a typical recipe like this can be produced according to the invention with a similar Recipe, which PVB recyclate together with freshly made PVB contains, and a third recipe, which conventional PVC contains, has been compared. It turns out that the inventor Floor coverings according to the invention meet all requirements and such probably pure PVB, as well as PVC flooring in many respects are superior.
