Definitions

• the present invention relates to a glass fibre mat. It further relates to products containing glass fibre mats, particularly a CV floor covering comprising a glass fibre mat as a structural layer.
• Glass fibre mats are known in multifarious embodiments and for various applications. Also known are customary methods of producing glass fibre mats from glass fibres and binders. A significant application of glass fibre mats is their use as a carrier material in floor coverings, particularly in CV (Cushioned Vinyl) floor coverings.
• the glass fibre mat is typically initially impregnated in a first step with a PVC paste (particularly Plastisol).
• the PVC paste is usually applied to the glass fibre mat by means of a coating knife in a predetermined layer thickness or with a predetermined surface weight (e.g. approx. 400 g/m 2 ).
• a further layer of PVC paste is then applied to the glass fibre mat impregnated in such a way, wherein the surface weight of this second layer can typically lie roughly within the same order of magnitude as the impregnating coating.
• the back foaming i.e. the application of an elastically flexible coating to the back side of the glass fibre mat, then takes place.
• the usable side can then receive a final finishing, for example by means of a coating of clear varnish or other special coatings.
• This kind of production of CV floor coverings has been known in the PVC industry for some time and is widely used in different variants.
• the glass fibre mat forming the carrier layer should exhibit good mechanical strength, namely both during the processing and also during the use of the floor covering designed and produced using said glass fibre mat. It is therefore important for both the PVC paste and also the back foaming to create an optimal mechanical connection with the glass fibre mat, so that these layers are prevented from separating from the glass fibre mat when the floor covering is in use.
• the PVC paste which is applied to the glass fibre mat by means of a coating knife, as described above, must be prevented from penetrating through said glass fibre mat.
• the present invention is aimed at providing a glass fibre mat which is ideally suited for use as a carrier material in a CV floor covering, in that is satisfies all the requirements described above in a practical manner and, to this extent, is superior to the prior art in its overall properties.
• a glass fibre mat comprising glass fibres of a first kind, glass fibres of a second kind and a binding agent, wherein the glass fibres of the first kind are characterized by a mean fibre diameter of under 6 ⁇ m and compliance with the EC Protocol “ECB/TM/27 rev. 7” and the glass fibres of the second kind are characterized by a mean fibre diameter of over 6 ⁇ m, wherein furthermore the ratio between the weight component of glass fibres of the first kind and the weight component of glass fibres of the second kind is between 0.01 and 0.15 and, in addition, the surface weight of the glass fibre mat is between 25 g/m 2 and 80 g/m 2 .
• the glass fibre mat according to the invention comprises various glass fibres connected to one another by means of a binding agent, namely relatively thin glass fibres of the first kind on the one hand, i.e. those with a mean fibre diameter of under 6 ⁇ m and, on the other hand, relatively thick glass fibres of the second kind, i.e.
• the weight component of glass fibres of the first kind in the glass fibre composition is significantly smaller than the weight component of glass fibres of the second kind, in that the ratio between the weight component of glass fibres of the first kind and that of glass fibres of the second kind lies between 0.01 and 0.15, wherein furthermore glass fibres of the first kind within the meaning of the criteria according to the EC Protocol “ECB/TM/27 rev. 7” (Biopersistence of Fibres; Intratracheal Instillation) are not biopersistent and the surface weight of the glass fibre mat lies between 25 g/m 2 and 80 g/m 2 .
• the properties of the corresponding glass fibre mat make it particularly suitable, especially with regard to the use described above, although they also allow a use of the glass fibre mat according to the invention associated with significant advantages in a series of other applications, in which similar requirements are made of the glass fibre mat (see below).
• the glass fibre mat according to the invention exhibits no significant loss in terms of mechanical properties such as strength, in particular, wherein at the same time, however, the risk that (in the preferred application described above) PVC paste penetrates through the glass fibre mat and forms lumps on the back side is significantly reduced compared with the relevant prior art.
• the surface of the finished floor covering can be improved by minimizing irregularities on the usable side.
• the need for PVC paste which is required in order to impregnate the glass fibre mat, can be reduced when using the glass fibre mat according to the invention, namely without the bond between the glass fibre mat and the impregnation being adversely affected as a result of this. Because the microfibres, i.e.
• glass fibres of the first kind exhibiting a mean fibre diameter of under 6 ⁇ m are furthermore not biopersistent (see above), the glass fibre mat according to the invention and the products manufactured using it are non-hazardous from a health perspective; this is because the glass fibres released particularly during processing (particularly at raw edges) can cause no harm in the human body, because they are either not respirable (this is the case with glass fibres of the second kind) or, however, are dissolved in the body by bodily fluids (this is the case with glass fibres of the first kind).
• glass fibres of the second kind may likewise be non-biopersistent, they need not necessarily be so, which is an important aspect both with regard to flexibility, which concerns the glass used for glass fibres of the second kind, and also with regard to production costs.
• the glass fibre mat according to the invention can be used particularly advantageously as a cover for interior elements, particularly of a motor vehicle, particularly as a cover panel or other interior facing.
• the mean fibre diameter of glass fibres of the first kind is between 0.5 ⁇ m and 6 ⁇ m, preferably between 0.6 ⁇ m and 3.0 ⁇ m, particularly preferably between 0.6 ⁇ m and 1.5 ⁇ m.
• the mean fibre diameter of the glass fibres of the second kind is between 6 ⁇ m and 13 ⁇ m.
• the mean fibre diameter of the glass fibres of the second kind is particularly favourable for the mean fibre diameter of the glass fibres of the second kind to be between 6 ⁇ m and 13 ⁇ m.
• Glass fibres of the second kind particularly preferably comprise C-glass and/or E-glass, wherein T-glass for glass fibres of the second kind is also highly suitable for various applications. It is particularly advantageous in this case for glass fibres of the second kind to comprise a mixture of at least two different kinds of glass fibre. If the mixture of glass fibres of the second kind in this respect comprises both C-glass and also E-glass, it is preferable for the proportion of glass fibres comprising C-glass in the mixture of glass fibres of the second kind to be greater than the proportions of glass fibres comprising E-glass, wherein the proportion of glass fibres comprising C-glass in the mixture of glass fibres of the second kind may even be substantially greater within the framework of the present invention than the proportions of glass fibres comprising E-glass.
• ratio indicated above is in turn favourable with regard to the particular properties of the glass fibre mat according to the invention described above, as they are useful, particularly in flooring applications. For other applications, however, other ratios may also be entirely favourable, even up to a proportion of 100% of glass fibres comprising E-glass accounting for fibres of the second kind.
• glass fibres of the second kind particularly preferably have a mean length/diameter ratio of between 500 and 2000.
• This proportion of glass fibres of the second kind bears a special relationship to the particular function thereof within the glass fibre mat, particularly with regard to mechanical strength (see above).
• the ratio between the weight component of glass fibres of the first kind and the weight component of glass fibres of the second kind for typical applications of the glass fibre mat according to the invention is preferably between 0.03 and 0.08, particularly preferably between 0.04 and 0.06.
• the aforementioned ratio is favourably less than 0.055, ideally less than 0.048.
• the surface weight of the glass fibre mat according to the invention lies between 40 g/m 2 and 60 g/m 2 .
• very good results can be achieved, however, with values that differ from these, e.g. a ratio between the weight component of glass fibres of the first part and the weight component of glass fibres of the second kind of less than 0.03.
• binding agent of the glass fibre mat according to the invention there is significant latitude here, which may particularly take account of the subsequent use of the glass fibre mat according to the invention.
• Particularly advantageous binding agents are urea resins and polyacrylic acid binders.
• the binding agent may, however, also comprise polyacrylic acid.
• Outstanding properties result when the binding agent comprises a mixture of urea resin and a polymer dispersion or a mixture of polyacrylic acid binders and a polymer dispersion.
• the binder may, depending on the designated subsequent use of the glass fibre mat in each case according to the invention, contain an additive (or a plurality of additives), which may account for up to 50% of the total weight of the binder.
• the additive may specifically modify or else optimize the properties of the binder in this case with regard to the individual determination of the glass fibre mat.
• Typical additives are, for example, kaolin and TiO 2 .
• the binder not only can the binder be technically optimized by additives, but additives are also capable of reducing costs by being able to make an expensive binding agent “go further”.
• the porosity of the glass fibre mat lies within the range of roughly 1000 l/m 2 s and roughly 3000 l/m 2 s, wherein a porosity of between roughly 1500 l/m 2 s and roughly 2500 l/m 2 s is particularly favourable.
• the above values for a preferred porosity are based on the measurement standard DIN EN ISO9237, namely for a differential pressure of 100 Pa.
• the present invention does not relate exclusively to the untreated glass fibre mat. Instead, the invention also relates particularly to a glass fibre mat pretreated for subsequent specific further processing, particularly provided with additional impregnation, wherein the impregnating agent may be particularly a plastisol or another PVC-based means. Furthermore, the present invention also extends to the finished CV floor covering produced using the glass fibre mat according to the invention, which CV floor covering comprises a usable layer and a structural layer, wherein the structural layer comprises a glass fibre mat according to the invention provided with impregnation (see above).
