Description

Glasfaservlies sowie Glasfaservliese enthaltende Erzeugnisse  Glass fiber fleece and glass fiber nonwoven products containing
Die vorliegende Erfindung betrifft ein Glasfaservlies. Sie betrifft des Weiteren Glasfaservliese enthaltende Erzeugnisse, insbesondere einen ein Glasfaservlies als Strukturschicht umfassenden CV-Bodenbelag . The present invention relates to a glass fiber fleece. It further relates to glass fiber nonwoven fabric containing products, in particular a glass fiber nonwoven as a structural layer comprehensive CV flooring.
Glasfaservliese sind in mannigfaltigen Ausführungen und für diverse Anwendungen bekannt. Ebenfalls bekannt sind übliche Verfahren zur Herstellung von Glasfaservliesen aus Glasfasern und Binder. Eine wesentliche Anwendung von Glasfaservliesen bildet die Verwendung als Trägermaterial in Bodenbelägen, namentlich in CV (Cushioned Vinyl ) -Bodenbelägen . Bei der Herstellung von CV- Bodenbelägen wird typischerweise das Glasfaservlies zunächst in einem ersten Schritt mit einer PVC- Paste (insbesondere Plastisol) imprägniert. Hierzu wird üblicherweise die PVC-Paste in einer vorgegebenen Schicht- dicke bzw. mit einem vorgegebenen Flächengewicht (z.B. ca. 400 g/m2) mittels Rakel auf das Glasfaservlies aufgebracht. Anschließend wird auf das solchermaßen imprägnierte Glasfaservlies eine weitere Schicht der PVC- Paste aufgebracht, wobei das Flächengewicht dieser zweiten Schicht typischerweise in etwa in der gleichen Größenordnung wie die Imprägnierbeschichtung liegen kann. Anschließend erfolgt die Rückenbeschäumung , d.h. das Aufbringen einer elastisch nachgiebigen Beschich- tung auf die Rückseite des Glasfaservlieses. Die Nutzseite kann anschließend ein abschließendes Finishing erhalten, beispielsweise durch Beschichtung mittels Klarlack oder sonstige Spezialbeschichtungen. Die derartige Herstellung von CV-Bodenbelägen ist in der PVC- Industrie seit langem bekannt und wird in verschiedenen Varianten in großem Umfang angewandt. Glass fiber webs are known in manifold designs and for various applications. Also known are conventional methods for the production of glass fiber webs of glass fibers and binders. An essential application of glass fiber webs is the use as a substrate in floor coverings, namely in CV (Cushioned Vinyl) floor coverings. In the production of CV floor coverings, the glass fiber fleece is typically first impregnated with a PVC paste (in particular plastisol) in a first step. For this purpose, usually the PVC paste in a predetermined layer thickness or with a predetermined basis weight (eg, about 400 g / m 2 ) applied by means of a doctor blade on the glass fiber fleece. Subsequently, a further layer of the PVC paste is applied to the thus impregnated glass fiber fleece, wherein the basis weight of this second layer may typically be approximately of the same order of magnitude as the impregnating coating. Then the backseaming takes place, ie the application of an elastically yielding coating to the backside of the glass fiber fleece. The Nutzseite can then a final finishing obtained, for example by coating with clearcoat or other special coatings. Such production of CV floor coverings has long been known in the PVC industry and is widely used in various variants.
An das die Trägerschicht bildende Glasfaservlies werden dabei verschiedene Anforderungen gestellt, die teilweise in einem gewissen Konfliktverhältnis zueinander stehen. So soll das Glasfaservlies eine gute mechanische Festigkeit aufweisen, und zwar sowohl während der Verarbeitung als auch während der Nutzung des unter seiner Verwendung hergestellten, ausgelegten Bodenbelags. Sodann ist es wichtig, dass sowohl die PVC-Paste als auch die Rückenbeschäumung eine optimale mechanische Verbindung zu dem Glasfaservlies eingehen, damit eine Ablösung dieser Schichten von dem Glasfaservlies während der Benutzung des Bodenbelags vermieden wird. Auf der anderen Seite muss allerdings vermieden werden, dass PVC-Paste, die, wie dargelegt, mittels Rakel auf das Glasfaservlies aufgebracht wird, durch dieses hindurch dringt; denn ansonsten entstehen auf der Rückenseite des Glasfaservlieses, wo später die Rückenbeschäumung aufgebracht wird, mehr oder weniger ausgeprägte PVC- Klümpchen, die den Komfort beim Gehen auf dem CV- Bodenbelag substantiell beeinträchtigen. Weiterhin spielen wie üblich Kostenaspekte eine Rolle, und zwar sowohl was die Herstellung des Glasfaservlieses betrifft, als auch im Hinblick auf dessen Imprägnierung mit PVC-Paste, wobei der Verbrauch an PVC-Paste für die Imprägnierung maßgeblich von der Dicke und den Eigenschaften (Porenvolumen, Durchlässigkeit, Saugfähigkeit, Porengrößenverteilung) des Glasfaservlieses abhängt. At the glass fiber web forming the carrier layer, various requirements are made, some of which are in conflict with each other. Thus, the glass fiber nonwoven should have good mechanical strength, both during processing and during use of the flooring made using it. Then it is important that both the PVC paste and the backsheet form an optimal mechanical connection to the glass fiber fleece, in order to avoid detachment of these layers from the glass fiber fleece during use of the floor covering. On the other hand, however, it must be avoided that PVC paste, which, as stated, applied by means of a doctor blade to the glass fiber fleece, penetrates through this; because otherwise arise on the back side of the glass fiber fleece, where later the Rückenbeschäumung is applied, more or less pronounced PVC lumps that affect the comfort when walking on the CV flooring substantially. Furthermore, as usual, cost aspects play a role, both as regards the manufacture of the glass fiber mat and in terms of its impregnation with PVC paste, the consumption of PVC paste for the Impregnation largely dependent on the thickness and properties (pore volume, permeability, absorbency, pore size distribution) of the glass fiber fleece.
Die vorliegende Erfindung ist darauf gerichtet, ein Glasfaservlies bereitzustellen, das sich in hervorragender Weise für die Verwendung als Trägermaterial in einem CV-Bodenbelag eignet, indem es alle vorstehend dargelegten Anforderungen in praxisgerechter Weise erfüllt und insoweit in seinen Gesamteigenschaften dem Stand der Technik überlegen ist. The present invention is directed to providing a glass fiber nonwoven that is excellently suited for use as a substrate in a CV flooring by satisfying all of the requirements set out above in a practical manner, and thus far superior to the state of the art in its overall properties.
Gelöst wird diese Aufgabenstellung gemäß der vorliegenden Erfindung, wie im Anspruch 1 angegeben, durch ein Glasfasern einer ersten Art, Glasfasern einer zweiten Art und ein Bindemittel umfassendes Glasfaservlies, wobei die Glasfasern der ersten Art sich durch einen mittleren Faserdurchmesser von weniger als 6 μτη sowie die Einhaltung des EC Protocol "ECB/TM/27 rev. 7" und die Glasfasern der zweiten Art sich durch einen mittleren Faserdurchmesser von mehr als 6 μιτι auszeichnen, wobei weiterhin das Verhältnis zwischen dem Gewichtsanteil der Glasfasern der ersten Art und dem Gewichtsanteil der Glasfasern der zweiten Art zwischen 0,01 und 0,15 beträgt und ferner das Flächengewicht des Glasfaservlieses zwischen 25 g/m2 und 80 g/m2 liegt. This object is achieved according to the present invention, as indicated in claim 1, by a glass fibers of a first type, glass fibers of a second type and a binder comprising glass fiber fleece, wherein the glass fibers of the first type by a mean fiber diameter of less than 6 μτη and the Compliance with the EC Protocol "ECB / TM / 27 rev. 7" and the glass fibers of the second type are characterized by a mean fiber diameter of more than 6 μιτι, further wherein the ratio between the weight fraction of the glass fibers of the first type and the weight fraction of the glass fibers of second type is between 0.01 and 0.15 and further, the basis weight of the glass fiber fleece between 25 g / m 2 and 80 g / m 2 .
Für das erfindungsgemäße Glasfaservlies ist somit, mit anderen Worten, eine spezifische Kombination synerge- tisch zusammenwirkender Merkmale dergestalt charakte- ristisch, dass es aus verschiedenen mittels eines Bindemittels miteinander verbundenen Glasfasern besteht, nämlich relativ dünnen, d.h. einen mittleren Faserdurchmesser von weniger als 6 μχη aufweisenden Glasfasern erster Art einerseits und relativ dicken, d.h. In other words, a specific combination of synergistically interacting features is characterized in such a way for the glass fiber fleece according to the invention. Rist that it consists of different interconnected by means of a binder glass fibers, namely relatively thin, ie a mean fiber diameter of less than 6 μχη having glass fibers of the first kind on the one hand and relatively thick, ie
einen mittleren Faserdurchmesser von mehr als 6 μπι aufweisenden Glasfasern zweiter Art andererseits, wobei der Gewichtsanteil der Glasfasern der ersten Art an der Glasfaserzusammensetzung wesentlich geringer ist als der Gewichtsanteil der Glasfasern der zweiten Art, indem das Verhältnis zwischen den Gewichtsanteilen der Glasfasern der ersten Art und dem der Glasfasern der zweiten Art zwischen 0,01 und 0,15 liegt, wobei weiterhin die Glasfasern der ersten Art im Sinne der Kriterien nach dem EC Protocol "ECB/TM/27 rev . 7" an average fiber diameter of more than 6 μπι having glass fibers of the second kind on the other hand, wherein the weight fraction of the glass fibers of the first kind of the glass fiber composition is substantially less than the weight fraction of the glass fibers of the second type by the ratio between the proportions by weight of the glass fibers of the first type and the the glass fibers of the second type is between 0.01 and 0.15, and furthermore the glass fibers of the first type in the sense of the criteria according to the EC Protocol "ECB / TM / 27 rev. 7"
(Biopersistence of Fibres; Intratracheal Instillation) nicht biopersistent sind und das Flächengewicht des Glasfaservlieses zwischen 25 g/m2 und 80 g/m2 liegt. Die Eigenschaften des entsprechenden Glasfaservlieses machen dieses insbesondere im Hinblick auf die weiter oben dargelegte Verwendung besonders geeignet, lassen allerdings auch eine mit signifikanten Vorteilen verbundene Verwendung des erfindungsgemäßen Glasfaservlieses in einer Reihe anderer Anwendungen, in denen vergleichbare Anforderungen an das Glasfaservlies gestellt werden, zu (s. unten) . Ein insoweit bedeutsamer, durchaus überraschender Aspekt in diesem Zusammenhang besteht darin, dass das erfindungsgemäße Glasfaservlies trotz seines relativ niedrigen Flächengewichts von zwischen 25 g/m2 und 80 g/m2, das sogar noch unter dem typischen Flächengewicht von bekannten, für vergleichbare Anwendungen geeigneten und eingesetzten Glasfaservliesen, die keinerlei Mikrofasern enthalten, liegt, und somit trotz des insoweit gegenüber herkömmlichen Glasfaservliesen mit nur einer Art von Glasfasern reduzierten Anteils stärkerer Glasfasern keine signifikante Einbuße an mechanischen Eigenschaften wie insbesondere der Festigkeit aufweist, wobei zugleich jedoch das Risiko, dass (in der weiter oben dargelegten bevorzugten Anwendung) PVC-Paste das Glasfaservlies durchdringt und auf der Rückseite Klümpchen bildet, gegenüber dem bisher insoweit maßgeblichen Stand der Technik signifikant reduziert wird. Zugleich lässt sich in Anwendung des erfindungsgemäßen Glasfaservlieses, verglichen mit dem Stand der Technik, die Oberfläche des fertigen Bodenbelags verbessern, indem Unebenheiten auf der Nutzseite minimiert werden. Hervorzuheben ist weiterhin, dass sich in Anwendung des erfindungsgemäßen Glasfaservlieses der Bedarf an PVC-Paste, der zum Imprägnieren des Glasfaservlieses benötigt wird, reduzieren lässt, und zwar ohne dass hierdurch die Haftung zwischen dem Glasfaservlies und der Imprägnierung beeinträchtigt wird. Indem die Mikrofasern, d.h. die einen mittleren Faserdurchmesser von weniger als 6 μττι aufweisende Glasfasern der ersten Art weiterhin nicht biopersistent sind (Biopersistence of Fibers, Intratracheal Instillation) are not biopersistent and the basis weight of the glass fiber fleece is between 25 g / m 2 and 80 g / m 2 . The properties of the corresponding glass fiber fleece make it particularly suitable, in particular with regard to the use set out above, but also permit use of the glass fiber fleece according to the invention with significant advantages in a number of other applications in which comparable requirements are imposed on the glass fiber fleece (cf. below). An important, quite surprising aspect in this context is that the glass fiber fleece according to the invention, despite its relatively low basis weight of between 25 g / m 2 and 80 g / m 2 , even under the typical basis weight of known, suitable for comparable applications and used glass fiber webs that contain no microfibers, and thus, despite the so far compared to conventional glass fiber webs with only one type of glass fibers reduced proportion of stronger glass fibers has no significant loss of mechanical properties, in particular the strength but at the same time the risk that (in the preferred application set forth above) PVC paste penetrates the glass fiber fleece and forms lumps on the back, is significantly reduced compared to the hitherto prevailing state of the art. At the same time, the surface of the finished floor covering can be improved in use of the glass fiber fleece according to the invention, compared to the prior art, by minimizing unevennesses on the useful side. It should also be emphasized that the need for PVC paste, which is required for impregnating the glass fiber fleece, can be reduced when the glass fiber fleece according to the invention is used, without this impairing the adhesion between the glass fiber fleece and the impregnation. In that the microfibers, ie the glass fibers of the first type having an average fiber diameter of less than 6 μm, are furthermore not biopersistent
(s.o.), sind das erfindungsgemäße Glasfaservlies und die unter seiner Verwendung hergestellten Erzeugnisse unter Gesundheitsaspekten unbedenklich; denn die insbesondere während der Verarbeitung (insb. an Schnittkanten) freigesetzten Glasfasern können im menschlichen Körper keinen Schaden anrichten, weil sie entweder nicht lungengängig sind (dies gilt für die Glasfasern der zweiten Art) oder aber im Körper durch Körperflüssigkeit aufgelöst werden (dies gilt für die Glasfasern der ersten Art) . Insoweit können zwar die Glasfasern der zweiten Art ebenfalls nicht-biopersistent sein, sie müssen dies jedoch nicht, was ein wichtiger Aspekt ist sowohl im Hinblick auf die Flexibilität, was das für die Glasfasern der zweiten Art verwendete Glas betrifft, als auch im Hinblick auf die Herstellungskosten. (see above), the fiberglass fabric according to the invention and the products manufactured using it are harmless from health aspects; because in particular during processing (especially at cut edges) released glass fibers in human Do not cause damage to the body, either because they are not respirable (this applies to the second type of glass fibers) or dissolved in the body by body fluid (this applies to the first type of glass fibers). In that regard, although the glass fibers of the second type may also be non-biopersistent, they need not, which is an important aspect both in terms of flexibility in terms of the glass used for the glass fibers of the second type, and in view of production costs.
Wenngleich die vorstehend eingehend erörterte Verwendung des erfindungsgemäßen Glasfaservlieses bei der Herstellung von Bodenbelägen im Vordergrund steht, was die besondere Eignung des erfindungsgemäßen Glasfaservlieses betrifft, so stellt dies keinesfalls die einzige mögliche Verwendung dar. Diverse der vorstehend dargelegten, das erfindungsgemäße Glasfaservlies auszeichnenden Aspekte machen dieses vielmehr auch für eine Reihe anderer Anwendungen mit besonderem Vorteil einsetzbar. Zu nennen ist hier insbesondere die (einer herkömmlichen Tapete entsprechende) Verwendung als überstreichbarer Decken- und Wandbelag, in der aufgrund der Eigenschaften des Glasfaservlieses mit sehr geringem (nachträglichem) Farbauftrag eine hervorragende Oberflächengüte erzielbar ist, wobei weiterhin die äußerst geringe Tendenz, dass Farbe durch das Vlies hindurchtritt, sich sehr günstig auswirkt auf die Haftung des Glasfaservlieses als Decken- bzw. Wandbelag auf dem betreffenden Untergrund. Dass mit einer sehr geringen Menge an Wand- bzw. Deckenfarbe eine sehr gute Oberflächenqualität erzielbar ist, ist dabei nicht nur ein ökonomischer Aspekt. Auch bleibt so das Gewicht des Decken- und Wandbelags samt Farbauftrag, d.h. des gestrichenen Decken- und Wandbelags relativ gering, was seinerseits der Haftung des Glasfaservlieses auf dem Untergrund entgegenkommt. In sehr ähnlicher Weise gelten diese vorteilhaften Gesichtspunkte bei der Verwendung des erfindungsgemäßen Glasfaservlieses als Although the use of the fiberglass mat according to the invention discussed in detail above is in the foreground in the manufacture of floor coverings, which relates to the particular suitability of the glass fiber mat according to the invention, this is by no means the only possible use. Various of the aspects outlined above which characterize the glass fiber mat according to the invention make this rather also for a number of other applications with particular advantage. To mention here is in particular the (a conventional wallpaper corresponding) use as paintable ceiling and wall covering in which due to the properties of the glass fiber fleece with very little (subsequent) paint excellent surface quality can be achieved, further the extremely low tendency that color through the fleece passes, has a very favorable effect on the adhesion of the glass fiber fleece as ceiling or wall covering on the background. The fact that a very good surface quality can be achieved with a very small amount of wall or ceiling paint is not just an economic aspect. Also, the weight of the ceiling and wall covering including paint, ie the painted ceiling and wall covering remains relatively low, which in turn accommodates the adhesion of the glass fiber fleece on the ground. In a very similar manner, these advantageous aspects apply when using the glass fiber non-woven fabric according to the invention as
Oberflächenbeschichtung einer Baustoffplatte , insbesondere einer mineralischen Decken- oder Wandplatte, dergestalt, dass das Glasfaservlies werksseitig auf der vorgeformten Platte aufgebracht wird (insbesondere durch Kleben bzw. Auflaminieren) ; denn die spezifische Struktur des erfindungsgemäßen Glasfaservlieses verhindert ein Durchdringen des Klebstoffes von der Rückseite her zu der frontseitigen Oberfläche, d.h. der Sichtseite, so dass die Oberflächengüte der Sichtseite und das Farbhaftvermögen nicht durch Klebstoffspuren beeinträchtigt wird. Und ebenfalls ist das erfindungsgemäße Glasfaservlies aufgrund seiner dargelegten günstigen Eigenschaften mit besonderem Vorteil als Abdeckung für Innenraumelemente , insbesondere eines Kraftfahrzeugs, insbesondere als Deckenplatte oder sonstige Innen- raumauskleidung einsetzbar. Surface coating of a building material, in particular a mineral ceiling or wall plate, such that the glass fiber fleece is applied to the factory preformed plate (in particular by gluing or lamination); because the specific structure of the glass fiber fleece according to the invention prevents penetration of the adhesive from the back to the front surface, i. the visible side, so that the surface quality of the visible side and the Farbhaftvermögen is not affected by traces of adhesive. And likewise, the glass fiber fleece according to the invention is due to its stated favorable properties with particular advantage as a cover for interior elements, in particular a motor vehicle, in particular as a ceiling panel or other interior space liner used.
Die vorstehend dargelegten besonderen Vorteile des erfindungsgemäßen Glasfaservlieses sind besonders ausgeprägt, wenn der mittlere Faserdurchmesser der Glasfasern der ersten Art zwischen 0,5 μιη und 6 μτη, bevorzugt zwischen 0,6 μτη und 3,0 μιτι, besonders bevorzugt zwischen 0,6 μπι und 1,5 μτη beträgt. The particular advantages of the glass fiber fleece according to the invention set out above are particularly pronounced when the average fiber diameter of the Glass fibers of the first type between 0.5 μιη and 6 μτη, preferably between 0.6 μτη and 3.0 μιτι, more preferably between 0.6 μπι and 1.5 μτη.
Weiterhin ist gemäß einer anderen bevorzugten Weiterbildung der vorliegenden Erfindung besonders günstig, wenn der mittlere Faserdurchmesser der Glasfasern der zweiten Art zwischen 6 μτη und 13 μπι beträgt. Namentlich in Kombination mit der vorstehend angegebenen bevorzugten Dimensionierung der Glasfasern der ersten Art ergeben sich besonders hervorragende Materialeigenschaften, die das entsprechende Glasfaservlies für die vorstehend dargelegten Anwendungen besonders attraktiv machen. Furthermore, according to another preferred embodiment of the present invention is particularly advantageous if the mean fiber diameter of the glass fibers of the second type between 6 μτη and 13 μπι. In particular in combination with the above-mentioned preferred dimensioning of the glass fibers of the first type, particularly excellent material properties result, which make the corresponding glass fiber fleece particularly attractive for the applications set out above.
Besonders bevorzugt bestehen die Glasfasern der zweiten Art aus C-Glas und/oder E-Glas, wobei für verschiedene Anwendungen auch T-Glas für die Glasfasern der zweiten Art sehr geeignet ist. Besonders vorteilhaft ist dabei, wenn die Glasfasern der zweiten Art aus einem Gemisch mindestens zweier unterschiedlicher Glasfasertypen bestehen. Umfasst das Gemisch von Glasfasern zweiter Art in diesem Sinne sowohl aus C-Glas wie auch aus E-Glas bestehende Glasfasern, so ist bevorzugt der Anteil von aus C-Glas bestehenden Glasfasern an dem Gemisch von Glasfasern zweiter Art größer als die Anteile von aus E-Glas bestehenden Glasfasern, wobei der Anteil von aus C-Glas bestehenden Glasfasern an dem Gemisch aus Glasfasern zweiter Art im Rahmen der vorliegenden Erfindung sogar wesentlich größer sein kann als die Anteile von aus E-Glas bestehenden Glasfasern. Auch das vorstehend angegebene Verhältnis ist wiederum günstig im Hinblick auf die weiter oben dargelegten besonderen Eigenschaften des erfindungsgemäßen Glasfaservlieses, wie sie insbesondere in Flooring-Anwendungen nützlich sind. Für andere Anwendungen können indessen durchaus auch andere Verhältnisse günstig sein, und zwar beispielsweise bis hin zu einem Anteil von 100 % von aus E-Glas bestehenden Glasfasern an den Fasern der zweiten Art. Particularly preferably, the glass fibers of the second type of C glass and / or E glass, with T glass for the glass fibers of the second kind is very suitable for different applications. It is particularly advantageous if the glass fibers of the second type consist of a mixture of at least two different types of glass fiber. If the mixture of glass fibers of the second type in this sense comprises glass fibers composed of both C-glass and E-glass, the proportion of glass fibers consisting of C-glass on the mixture of glass fibers of the second type is preferably greater than the proportions of E In the present invention, the proportion of glass fibers consisting of C glass to the mixture of glass fibers of the second type may even be substantially greater than the proportions of glass fibers consisting of E glass. That too given ratio is again favorable in view of the above-mentioned specific characteristics of the glass fiber non-woven fabric according to the invention, as they are particularly useful in Flooring applications. However, other conditions may well be favorable for other applications, for example up to a proportion of 100% of glass fibers made of E glass on the fibers of the second type.
Gemäß einem abermals anderen Aspekt der vorliegenden Erfindung weisen die Glasfasern der zweiten Art besonders bevorzugt ein mittleres Längen- /Durchmesserverhältnis von zwischen 500 und 2000 auf. Diese According to yet another aspect of the present invention, the glass fibers of the second type particularly preferably have an average length / diameter ratio of between 500 and 2,000. These
Proportion der Glasfasern der zweiten Art steht in spezifischer Beziehung zu deren besonderer Funktion innerhalb des Glasfaservlieses, insbesondere im Hinblick auf die mechanische Festigkeit (siehe oben) . Proportion of the glass fibers of the second type is in specific relation to their particular function within the glass fiber fleece, in particular with regard to the mechanical strength (see above).
Gemäß einer abermals anderen bevorzugten Weiterbildung der vorliegenden Erfindung beträgt - für typische Anwendungsfälle des erfindungsgemäßen Glasfaservlieses - das Verhältnis zwischen dem Gewichtsanteil der Glasfasern der ersten Art und dem Gewichtsanteil der Glasfasern der zweiten Art bevorzugt zwischen 0,03 und 0,08, besonders bevorzugt zwischen 0,04 und 0,06. Günstigerweise beträgt das besagte Verhältnis weniger als 0,055, idealerweise weniger als 0,048. Wiederum ergeben sich in diesem Falle ganz besonders vorteilhafte Eigenschaften des erfindungsgemäßen Glasfaservlieses insbesondere im Hinblick auf dessen mögliche Verwendung als Träger- material in CV-Bodenbelägen mit hervorragenden Eigenschaften. In dieser Hinsicht ist es für typische Anwendungsfälle weiterhin günstig, wenn das Flächengewicht des Glasfaservlieses zwischen 40 g/m2 und 60 g/m2 liegt. Für spezifische Anwendungsfälle könne indessen mit hiervon abweichenden Werten, z.B. einem Verhältnis zwischen dem Gewichtsanteil der Glasfasern der ersten Art und dem Gewichtsanteil der Glasfasern der zweiten Art von weniger als 0,03, sehr gute Resultate erzielt werden . According to yet another preferred embodiment of the present invention is - for typical applications of the glass fiber nonwoven fabric - the ratio between the weight fraction of the glass fibers of the first type and the weight fraction of the glass fibers of the second type preferably between 0.03 and 0.08, more preferably between 0 , 04 and 0.06. Conveniently, said ratio is less than 0.055, ideally less than 0.048. Again, in this case, very particularly advantageous properties of the glass-fiber non-woven fabric according to the invention result, in particular with regard to its possible use as carrier material in CV flooring with excellent properties. In this regard, it is further favorable for typical applications, if the basis weight of the glass fiber fleece between 40 g / m 2 and 60 g / m 2 . However, for specific applications very good results could be achieved with values deviating therefrom, for example a ratio between the proportion by weight of the glass fibers of the first type and the weight proportion of the glass fibers of the second type of less than 0.03.
Was das Bindemittel des erfindungsgemäßen Glasfaservlieses betrifft, so besteht hier ein erheblicher As far as the binder of the glass fiber nonwoven according to the invention is concerned, there is a considerable amount here
Spielraum, der insbesondere die spätere Verwendung des erfindungsgemäßen Glasfaservlieses berücksichtigen kann. Besonders vorteilhafte Bindemittel sind Harnstoffharze und Polyacrylsäure-Binder . Das Bindemittel kann aber auch Polyacrylsäure umfassen. Hervorragende Eigenschaften ergeben sich dann, wenn das Bindemittel eine Mischung aus Harnstoffharz und Polymerdispersion oder eine Mischung Polyacrylsäure-Binder und Polymerdispersion umfasst. Scope that can take into account in particular the subsequent use of the glass fiber mat according to the invention. Particularly advantageous binders are urea resins and polyacrylic acid binders. The binder may also comprise polyacrylic acid. Outstanding properties result when the binder comprises a mixture of urea resin and polymer dispersion or a mixture of polyacrylic acid binder and polymer dispersion.
Ebenfalls ein erheblicher Spielraum besteht dahingehend, was den Gewichtsanteil des Bindemittels an dem Glasfaservlies angeht, wobei insoweit auch das jeweils verwendete spezifische Bindemittel sowie die Verwendung des Glasfaservlieses eine Rolle spielen können. Für die hier im Vordergrund stehende mögliche Verwendung als Trägermaterial eines CV-Bodenbelags ist ein Gewichtsan- teil des Bindemittels zwischen 15 % und 35 %, bevorzugt zwischen 20 % und 30 % des Gesamtgewichts des Glasfaservlieses von Vorteil. There is also considerable room for maneuver with regard to the proportion by weight of the binder in the glass fiber fleece, in which respect the specific binder used in each case as well as the use of the glass fiber fleece can play a role. For the possible use here as support material of a CV floor covering, a weight Part of the binder between 15% and 35%, preferably between 20% and 30% of the total weight of the glass fiber fleece advantage.
Der Binder kann, je nach der bestimmungsgemäßer! späteren Verwendung des jeweiligen erfindungsgemäßen Glasfaservlieses, ein Additiv (oder mehrere Additive) The binder can, depending on the intended! later use of the respective glass fiber nonwoven fabric according to the invention, an additive (or several additives)
enthalten, das (die) bis zu 50% des Gesamtgewichts des Binders ausmachen kann (können) . Das Additiv (bzw. die Additive) kann (können) dabei die Eigenschaften des Binders im Hinblick auf die individuelle Bestimmung des Glasfaservlieses spezifisch modifizieren bzw. optimieren. Typische Additive sind beispielsweise Kaolin und Ti02. Allerdings kann durch Additive nicht nur der Binder technisch optimiert werden; auch eignen sich Additive dazu, die Kosten zu senken, indem sie teures which can make up to 50% of the total weight of the binder. The additive (or the additives) can thereby specifically modify or optimize the properties of the binder with regard to the individual determination of the glass fiber fleece. Typical additives are, for example, kaolin and TiO 2 . However, not only the binder can be technically optimized by additives; Also, additives are useful to cut costs by making expensive ones
Bindemittel "strecken" können. Binders "stretch" can.
Im Hinblick auf die weiter oben dargelegten Zusammenhänge ist es für typische Anwendungen vorteilhaft, wenn die Porosität des Glasfaservlieses innerhalb der Bandbreite von etwa 1000 l/m2s und etwa 3000 l/m s liegt, wobei eine Porosität zwischen etwa 1500 l/m s und etwa 2500 l/m2s besonders günstig ist. Die vorstehenden Werte für eine bevorzugte Porosität stellen auf die Messnorm DIN EN IS09237 ab, und zwar für einen In view of the relationships set forth above, it is advantageous for typical applications when the porosity of the fiberglass mat is within the bandwidth of about 1000 l / m 2 s and about 3000 l / ms, with a porosity between about 1500 l / ms and about 2500 l / m 2 s is particularly favorable. The above values for a preferred porosity are based on the measurement standard DIN EN IS09237, namely for one
Differenzdruck von 100 Pa . Differential pressure of 100 Pa.
Die vorliegende Erfindung bezieht sich nach den vorstehenden Ausführungen nicht allein auf das unbehandelte Glasfaservlies. Vielmehr bezieht sich die Erfindung insbesondere auch auf ein zur späteren spezifischen Weiterverarbeitung vorbehandeltes, insbesondere mit einer zusätzlichen Imprägnierung versehenes Glasfaservlies, wobei es sich bei dem Imprägniermittel insbesondere um Plastisol oder ein sonstiges PVC-basiertes Mittel handeln kann. Weiterhin erstreckt sich die vorliegende Erfindung auch auf den fertigen, unter Verwendung des erfindungsgemäßen Glasfaservlieses The present invention, according to the above, does not refer to the untreated alone Fiberglass mat. Rather, the invention relates in particular to a pretreated for later specific processing, in particular provided with an additional impregnation fiberglass mat, wherein it may be in the impregnating agent in particular plastisol or other PVC-based agent. Furthermore, the present invention also extends to the finished, using the glass fiber mat according to the invention
hergestellten CV-Bodenbelag , der eine Nutzschicht und eine Strukturschicht umfasst, wobei die Strukturschicht ein mit einer Imprägnierung versehenes erfindungsgemäßes Glasfaservlies (s.o.) umfasst. produced CV floor covering, which comprises a wear layer and a structural layer, wherein the structural layer comprises a provided with an impregnation according to the invention glass fiber fleece (s.o.).
