Description

The present invention relates to a web-shaped flexible surface material of a halogen compound-free plastic material, especially for a patterned floor covering, and a method for producing a heterogeneous surface material.

The invention relates to the area of application for a surface material made of thermoplastic, with a durable surface equipped with a colored pattern, as well as the production of a coating-like plastic track, especially in the case of surface wear-resistant floor coverings, and concerns a multi-layer construction of a floor covering of a PVC-free plastic material with a shaped surface and a procedure for its production.

Polyvinyl chloride, abbreviated as PVC, which is a thermoplastic, has been used as a starting material for floor coverings of a plastic substance by adding a plasticizer such as PVC plasticizer, which, using fillers, is processed into a homogeneous, web-shaped floor covering. The good properties of these materials, which in powder form are used as tasteless and odorless products as additives, consist in the fact that they are difficult to ignite, have a low water absorption capacity and exhibit good electrical insulation properties. Furthermore, it turns out that PVC, through its good processing properties, provides a low material cost. Processed into products, these are resistant to many types of cleaning agents and solvents that are commonly used on floor coverings, and are not attacked by them. The floor covering which is produced on the basis of PVC and which consists of plastic webs, is physiologically invulnerable and is distinguished by a durable surface, as the wear resistance is dependent on the filler content. During production, the surface can be shaped with colors and equipped with a pattern. Furthermore, plastic webs that are produced on a PVC basis can easily be processed into large surfaces by welding.

Although the basic material PVC has very good conditions for the production of plastic sheets due to the material properties, and also shows advantages for further processing, i.e. for laying the plastic sheet into a surface-covering floor covering, this material has a shortcoming that burdens the environment, namely the high chlorine content. The plastic web is produced from a PVC that contains a plasticizer. Thus, the PVC powder for processing is mixed with a plasticizer, for example a paste or a flowable dry mixture (Dryblend), which then, through heating, transforms into a homogeneous mass. Various materials are used as plasticizers, which have a more or less harmful influence on health, when the plasticizer part diffuses from the processed materials.

To circumvent the above-mentioned shortcoming, there are, for example, various proposals (from DE 3,507,665 and EP 0 321 760), which are aimed at the production of plastic webs with plasticizer-free additives. With this known production method, homogeneous plastic webs were to be produced, which were to exhibit similar properties to those produced on a PVC basis. This objective can only be met with respect to the effort of a plasticizer-free end product. All products produced with this method have the particular shortcoming that a comparable colored surface design cannot be achieved, which consists of PVC, and significant limitations must be taken with regard to wear resistance, as well as increased costs during the laying process. The reason for these deficiencies lies in the material properties of the additives used. According to the known solutions, ethylene-vinyl acetate copolymer is used as a binder for floor coverings in high mass proportions. Tracks or boards produced from this starting material are not suitable as floor coverings, as the material is too weak. For the surface design of PVC-free homogeneous plastic webs, there are known methods in which the parts that form the pattern in the material are pressed or melted in.

For the production of a PVC-free floor covering of ethylene-vinyl acetate copolymer, a method is known from DE 4 127 107 and EP-A 0 528 194 in which the binder ethylene copolymer with a very low density is added with 1% by weight zinc stearate and a sterically hindering phenol , which is immediately first mixed with a concentrate and then thoroughly mixed, under heat supply. This plasticized mixture is immediately drawn out into a foil in a calender plant. This foil of ethylene copolymer is duplicated by applying heat with a foil of ethylene-vinyl acetate copolymer with 8 percent polyethylene produced in the same procedure. The multi-layer foil obtained by this method is predominantly used as a translucent cover layer for floor coverings. The multi-layer foil obtained by this method is not sufficiently suitable for floor coverings, as this cannot compete with a floor covering produced on a PVC basis when it comes to the possibility of a colored and patterned design. Thus, this multi-layer foil is only suitable for use as a cover layer for other, weaker plastic webs. As the wear resistance of this multi-layer foil is not sufficient for floor coverings either, this proposed solution will not eliminate the lack of wear resistance of PVC-free floor coverings.

Although several different methods are known for forming web-shaped PVC-free plasters for floor coverings, the colored structures of the products produced in this way are not sharply defined. With this known production method for surface shaping, no satisfactory result has been achieved with regard to abrasion and scratch resistance.

The aim of the present invention is, on the one hand, to avoid a danger to health and the environment, which is present during use, or the addition of plasticizer in the case of a web-shaped floor covering produced on the basis of PVC additives, and on the other hand, by using other chlorine compound-free and plasticizer-free starting materials, to retain the positive properties of plastic webs produced on a PVC basis in terms of wear resistance, colour- and motif design and the favorable conditions of use, i.e. the positive possibility of laying, and maintaining and ensuring a high use value for surface formations for floor coverings with regard to plan characteristics and laying conditions, and in addition to achieving the necessary wear resistance in a high resistance strength in relation to for compressive and tensile loads.

The purpose of the invention is to provide a flexible web-shaped and patterned surface material of chlorine-free plastic, with a durable surface, especially for floor coverings, which comprises a collection of at least one web-shaped polymer melt and a uniformly shaped fiber material, which allows a surface design with a pattern and color additions, as well as an energy-saving procedure for producing a web-shaped heterogeneous surface material.

The purpose of the invention is achieved by developing a web-shaped flexible surface material made of a halogen compound-free plastic with a durable surface, especially for a patterned floor covering, where the surface material exhibits a heterogeneous structure and comprises at least one homogeneous, PVC-free polymer layer and a fiber-containing surface-forming base layer, which works like a staple bridge, whereby deposited PVC-free polymers from the polymer layer are pressed into the fiber structure of the base layer, and that between the polymer layer and the base layer there is a fiber/polymer mixed layer, and that the base layer consists of a fiber-containing surface formation provided with a specific pattern, which essentially includes colored motifs on the surface materials, and that the polymer layer is a transparent or translucent wear layer.

Furthermore, a web-shaped flexible surface material of a halogen compound-free plastic with a durable surface has been produced, especially for a patterned floor covering, where the surface material exhibits a heterogeneous structure and comprises at least two homogeneous, PVC-free polymer layers and a base layer, preferably on a fiber-containing surface formation existing base layer is arranged a specific, substantially colored pattern consisting of a motif, and the polymer layers are preferably arranged as transparent or translucent layers, one of which is transparent, but preferably colored toned intermediate layer and the other, which is used as a final layer on a heterogeneous structure , is arranged as a wear layer.

In addition, a web-shaped, flexible surface material comprising a halogen-free plastic with a durable surface has been provided, especially for colored or color-structured floor coverings, where the surface material exhibits a heterogeneous structure and comprises several, i.e. at least two, homogeneous, PVC-free polymer layers in a preferably fiber-containing surface formation shaped base layer, one of the polymer layers is preferably solid, solid and with a patterned or colored structured intermediate layer and the other, which forms the final layer of the heterogeneous structure of the surface material, is formed as a wear layer.

The wear layer of the web-shaped flexible surface material exhibits a prominent relief structure, preferably through thermoplastic shaping, to form the surface.

The base layer and the intermediate layer comprise a fiber-containing surface formation with therein ordered or disordered textiles and/or mineral fibres, the base layer serving as an adhesive bridge between the plate material and a laying surface, and the intermediate layer serving as an adhesive bridge between two polymer layers that cannot be joined using hitherto known technical means.

To ensure wear resistance, the wear layer comprises a mixture of one or more olefin components and one or more thermoplastic elastomer components, the molecular group of the fabric components forming a penetration network, where the thermoplastic elastomer components are the discontinuous phase and the olefin components are the continuous phase in the network connection of the wear layer.

For the colored shaping and patterning of the surface material, the inner surface of the base layer or the intermediate layer is equipped with a printed raster/resp. partial surface application of a thermoplastic binder, coated with an organic and/or inorganic color pigment.

When a surface material consisting of PVC-free polymer, on a coating surface is not slip-resistant, e.g. through gluing, in accordance with a further inventive feature, the web-shaped flexible surface material is equipped with a base layer consisting of a fiber-containing surface formation, which forms an adhesive bridge between the surface material and the laying surface of the floor covering.

Furthermore, it is between two homogeneous, non-joinable PVC-free polymer layers formed as one

heftebru a flat-shaped intermediate layer, essentially consisting of fiber material.

Furthermore, the task of proposing a method for producing a surface material in accordance with the present invention is solved by a method for producing a heterogeneous web-shaped flexible surface material, comprising at least one homogeneous, halogen-free transparent or translucent plastic layer with a durable surface, and at least one coating surface forming base layer consisting of fiber material which functions as a forming layer or as a binding bridge, in accordance with the invention by melting a polymer with technical means known to the person skilled in the art, producing from this polymer melt over a forming device, a polymer melt-film consisting surface formation with a defined thickness, and which is in a state of thermoplastic melt, and at the same time a base layer formed from a fiber mass, with or without a pattern, is introduced onto the inner facing surface of the thermoplastic flat formation in a joint gap in a pressing plant that includes at least two sealants, so that the present read a form-fitting adhesive bond, produced under the influence of a line or surface formation by a pressing force exerted on the base layer and on the polymeric surface formation, by pressing the fibrous base layer into the surface of the thermoplastic polymeric surface formation, which finally cools the thermoplastic polymeric surface formation .

Furthermore, a procedure for the production of a heterogeneous surface material is proposed, comprising at least two homogeneous, halogen compound-free plastic layers and one as a shaping layer and/

in or as an adhesive bridge to a base layer forming a coating surface and consisting of fiber material, in accordance with the invention, by melting a polymer, producing from this polymer melt over a forming device a surface formation with a defined thickness, and in the state of a thermoplastic melt at the same time introduce, on the inner facing surface of the thermoplastic surface formation, a base layer preferably formed from a fiber mass, with or without a pattern, in a joint gap in a pressing plant comprising

j at least two sealants, for the production of a form-fitting joint, produced under impact

of a line or surface formation by a pressing force that is exerted on the base layer and on the polymeric surface formation by pressing the fiber-shaped base layer into the surface of the thermoplastic polymeric surface formation, and this is then equipped in a similar manufacturing technique with a further polymer surface formation, the other polymer the surface formation in the state of the thermoplastic melt is placed on the first in the thermoplastic state, and finally this adhesive bond is cooled.

In accordance with the present invention, a method for the production of a heterogeneous surface material is also proposed, where the first homogeneous, PVC-free foil-like polymer surface formation is produced in a known manner from a polymer melt and this in the state of a thermoplastic melt is connected in a form-fitting manner by means of a pressing force from a sealant with, on one side, a adhesive bridge, to a base layer that forms a coating surface and consists of fiber material and, on the other side, with a fiber-formed and designable intermediate layer that can serve as an adhesive bridge between two non-joinable polymeric surface formations, since on the fiber-shaped interlayers designed as hinge bridges are further applied with a wear layer consisting of PVC-free polymer, which is obtained by the same technique from a polymer melt, in the form of a polymer gap, and with the help of a pressing force, performing sealant is connected to this hinge bridge in a form-fitting manner.

In a further design of the proposed procedure for the production of a surface material, a shape-matched adhesive bond is formed in a separate process between a first homogeneous PVC-free, foil-like polymeric surface formation produced in a known manner from a polymer melt and a pre-printed intermediate layer serving as an adhesive bridge, in state of a thermoplastic molten polymer surface formation produced under the influence of a force exerted through a sealant, and attached to this as a wear layer and pre-printed, as an adhesive bridge between two non-joinable polymeric surface formations serving as an intermediate layer consisting of a two-sided adhesive connection at the same time as a base layer serving as an adhesive bridge to the coating substrate is passed through a joint gap in a pressing plant consisting of at least two sealants, while at the same time one of a polymer melt produced in a known manner is placed in a thermoplastic state between the two-layer adhesive bond and the fiber-shaped base layer, while a form-fitting is produced between these and the intermediate layer set connection between the booklet connection on one side and the base layer on the other side.

Within the procedure, the base layer or the intermediate layer is carried out with a joint mechanism in the joint gap between two sealants designed for this purpose, mixed in a pressure step using a thermoplastic polymer as a binder mixed with organic and/or inorganic color pigments that are printed on with colored motifs consisting of raster or partial surface-shaped patterning. For the printing step, rotary gravure printing, rotary screen printing or thermal printing are used. While the production of surface material is carried out through a heated polymeric surface formation introduced into the joint gap, i.e. which is in a state of thermoplastic melt, which polymeric surface formation, which is printed with a motif on the base layer, respectively the intermediate layer, is heated and through that for the printing ink which binder, the thermoplastic polymer used is melted and thus bonded in the form-fitting connection between the base layer, or the intermediate layer and become integrated with the polymeric surface formation.

With the construction of a flexible, web-shaped surface material made of chlorine compound-free plastics proposed in accordance with the present invention, especially for use as a floor covering, there is a surface material which, due to that it is manufactured in accordance with the manufacturing method proposed by the invention, with low energy costs on the one hand and on the other hand through the use of cheap starting materials is cost-effective and at the same time has a high quality, as the known positive properties from PVC-based manufactured floor coverings reach this applies to plan conditions, wear resistance of the surface of the floor covering, resistance to tension and pressure loads and to cleaning agents containing solvents. The high tensile and compressive loads, as well as the good planar conditions of the surface material, can be traced back to the flat-shaped fiber layers, which act as joins for surface preservation. There is also a great opportunity for the formation of colors and colored patterns. Furthermore, it is through the structure in accordance with the present invention

option with an effect for plastic motif formation.

In what follows, the invention will be explained in more detail by means of examples of execution and with reference to the attached drawings, where

fig. 1 shows the construction of a surface material in accordance with the present invention, comprising a fibrous support layer and a wear layer consisting of PVC-free polymer in a cross-section,

fig. 2 shows a cross-sectional view of a surface material in accordance with the present invention, consisting of a fiber-containing base layer, a polymer intermediate layer and a polymer wear layer of PVC-free materials, and

fig. 3 shows a cross-section of a surface material in accordance with the present invention, consisting of a fiber-containing base layer, a polymer intermediate layer, a fiber-containing intermediate layer and a polymer wear layer.

A web-shaped flexible sheet material, which can especially be used for single- or multi-coloured, patterned or non-patterned floor coverings, shows a multi-layer structure. Irrespective of the layer structure depending on the purpose of application, a fiber-shaped base layer 1 is always arranged as the bottom layer, which comprises ordered or disordered textiles and/or mineral fibers, which on the one hand serves as an adhesive for a laying surface 2 to the surface material, and on the the other side is connected with a homogenous, PVC-free thermoplastic polymer layer that is connected in a form-fitting manner. In such a present two-layer structure, the fiber-shaped base layer 1 is the carrier for a pattern or structure of the surface material with one or multi-coloured motifs, as these are formed in a printing process and are formed from a raster or partial surface-shaped, from a thermoplastic binder containing inorganic and/or organic color pigment to an inner surface 4 of the base layer 1 arranged outlet 3. The homogeneous thermoplastic polymer layer consisting of a PVC-free plastic, is formed as a transparent or translucent wear layer 5. This wear layer 5 comprises, preferably for increasing the wear resistance, a mixture of one or more olefin components and one or more thermoplastic elastomer components. In this mixture, the molecular group forms the fabric components as a penetration network, with the thermoplastic elastomer components as discontinuous phase and the olefin components as continuous phase in the network connection.

In the case of a three-layer build-up of the plate material, which is essentially selected for uniform formation, is

between the wearing layer 5 and the fiber-shaped base layer 1, a thermoplastic polymer layer consisting of PVC-free plastic arranged as an intermediate layer 6. This can be both plain and patterned in itself. If the materials used in the wear layer 5 and the intermediate layer 6, which contain PVC-free plastic, cannot be joined/connected by known means due to material composition, between the polymeric wear layer 5 and the polymeric wear layer 6, there is an intermediate layer 7 which is fiber-shaped and has a tack-mediating function, which intermediate layer 7 corresponds to the structure of the base layer 1. The fiber-shaped intermediate layer 7 is inserted in the same way as the fibrous base layer 3 which carries a single or multi-coloured motif consisting of a design/pattern.

The wear layer 5 is equipped in the area of the surface 8 with a relief-active structure (not shown), preferably obtained through thermoplastic molding.

The production of the web-shaped flexible plate material is preferably carried out in traditional calender rolling mills, since in the case of a two-layer joining of the surface material, a roll gap between two calender rolls is on one side the fibrous material a base layer 1 or an intermediate layer 7 and on the other side at the same time a polymeric surface formation of a wear layer 5 or intermediate layer 6 in the form of a thermoplastic melt, which comprises polymer that has immediately passed from an extruder and produced over a width slit nozzle. Through a pressing force through the rollers on one side against the base layer 1 or intermediate layer 7 and on the other side against the polymeric surface formation, a fiber-shaped layer is connected in a form-fitting manner to the polymeric surface formation. The production of multilayer compounds of a surface material follows in procedural analogy.
