Abstract

A method for the production of highly abrasion resistant decorative paper and laminates , in particular for flooring, provides for application to a substrate (1) in strip form, by means of two distinct spreading steps (11, 21), of an anti-abrasion layer (12) consisting of a first polymeric composition incorporating a abrasion resistant particle substance such as corundum and, above the anti-abrasion layer (12), a protective layer (22) consisting of a second polymeric composition comprising at least one polymeric resin, cellulose fibres and particles and/or fibres of a material with high hardness and low abrasiveness, in particular glass spheres and/or fibres.

Description

"METHOD FOR THE PRODUCTION OP HIGHLY ABRASION RESISTANT DECORATIVE PAPER AND LAMINATES, IN PARTICULAR FOR FLOORING"
*** ***** *** TECHNICAL FIELD
The present invention relates to a method for the production of highly abrasion resistant decorative paper and laminates, incorporating such decorative paper, ; the decorative paper and laminates of the invention are applied particularly advantageously in the flooring field, but can be profitably used also in other applications, for example as wall or furniture coverings.
BACKGROUND ART Thermosetting polymeric resin-based laminates resistant to abrasion are well known in the art, for example for the production of floorings as a replacement for natural wooden floors; these laminates generally consist of one or more sheets of paper impregnated and spreaded with polymeric compositions and hot-rolled; the layer designed to remain exposed is normally provided with a decoration which reproduces the required drawing and/or colour; a protective anti-abrasion coating, the so-called overlay, which contains particles of a highly abrasion resistant material with (for example corundum) and which furthermore gives the laminate a brilliant look which is particularly satisfactory in terms of appearance, is press coupled with this decorative layer.
Coupling with an overlay is, however, relatively costly, both in terms of production costs and complexity of the process, and has the further drawback of resulting in general in laminates with poor flexibility.
DISCLOSURE OF INVENTION The present invention therefore aims to provide a method for the production of decorative paper and, therefore, laminates incorporating said decorative paper, in particular for covering surfaces of floors, furniture or walls, which is without the drawbacks highlighted in the known art; in particular an aim of the invention is to provide a method which is simple and relatively inexpensive to carry out and provides highly abrasion resistant decorative paper and laminates having at the same time a particularly satisfactory appearance and a high surface shine.
The present invention therefore relates to a method for the production of highly abrasion resistant decorative paper and laminates , in particular for flooring, the method comprising a first spreading step, in which a first polymeric composition incorporating a particle substance resistant to abrasion, such as corundum, is applied on a first face of a substrate in strip form to form an anti-abrasion layer; and a second spreading step, in which a second polymeric composition is applied to said anti-abrasion layer; the method being characterised in that said second polymeric composition comprises at least one polymeric resin and cellulose fibres, and in that the first polymeric composition and second polymeric composition are applied in respective distinct spreading steps to form respective separate and overlapping layers.
In this way, the method of the invention provides highly abrasion resistant decorative paper and laminates , at the same time having a particularly satisfactory appearance with a high surface shine, furthermore resulting simple and relatively inexpensive to carry out.
According to a further aspect of the invention, the second polymeric composition includes particles and/or fibres of a material with high hardness and low abrasiveness, in particular glass spheres and/or fibres. This avoids the further drawback of wear of the lamination presses due to contact with the abrasion resistant particle substance (in turn very abrasive) ; said substance, in fact, is entirely coated, whatever is the process of dispersion within the anti-abrasion layer, by the second polymeric composition which, by containing the particles and/or fibres of material with high hardness and low abrasiveness, protects the lamination presses, and by containing cellulose ensures a high surface shine, comparable or superior to that obtained with a traditional overlay.
Recourse to further protective layers, which would involve an increase in costs and complexity of the process, is therefore not necessary.
BRIEF DESCRIPTION OF THE DRAWING
The invention is further described with reference to the figure of the attached drawing, which illustrates in a schematic form the main steps for carrying out the method for the production of highly abrasion resistant decorative papers and laminates, in particular for flooring, in accordance with the invention.
BEST MODE FOR CARRYING OUT THE INVENTION In the attached figure, 1 indicates a substrate in strip form, in particular a strip of printed decorative paper presenting two opposite faces 2, 3; face 2 is provided with a decoration that reproduces the required drawing and/or colour.
The substrate 1 undergoes an impregnation step 4, in which the substrate 1 is immersed in a bath consisting of an aqueous solution of one or more polymeric components, in particular an aqueous solution of melamine resins (or similar) and/or polyvinyl alcohol; according to a preferred embodiment, the substrate 1 is impregnated in a bath of water and polyvinyl alcohol. The impregnation step is performed according to known procedures and in such a way as to leave in the substrate 1 from approximately 5 to approximately 20 and preferably around approximately 10 g/m2 when dried of melamine resin and/or polyvinyl alcohol.
The impregnated substrate 1 is then subjected to a first spreading step 11; preferably (but not necessarily) , the impregnated substrate 1 is subjected when wet to the first spreading step 11, without passing through drying steps.
In the first spreading step 11 a first polymeric composition, comprising one or more polymeric components, in particular a melamine resin or other similar thermosetting resin or polyvinyl alcohol or their mixtures, and an abrasion resistant particle substance, such as corundum, is applied on the face 2 to form an anti-abrasion layer 12.
The first spreading step 11 is performed by applying a quantity of polymeric composition such as to leave on the substrate 1 from approximately 10 to approximately 60 g/m2 when dried of polymeric components and from approximately 5 to approximately 50 g/m2 when dried of corundum (or analogous abrasion resistant particle substance) .
The face 3 is spreaded with melamine resin (or other similar thermosetting resin) , in a quantity of between approximately 10 and approximately 40 g/m2 when dried, to form a polymeric layer 7.
The first spreading step 11 can be performed with a spreading machine of any known type, for example by means of a roller spreading assembly, in particular by means of a reverse spreading system, or by means of a wire doctor blade ("Meyer bar") , or again by means of a flat-head spreading machine.
After passing through a dryer for a drying step 13 if necessary, the substrate 1 is subjected to a second spreading step 21.
In the second spreading step 21, a second polymeric composition, comprising at least one polymeric component, for example melamine resin or other similar thermosetting resin, cellulose fibres (preferably cellulose and/or alpha-cellulose microfibres) and particles and/or fibres of a material with high hardness and low abrasiveness, in particular glass spheres and/or fibres, is applied above the anti-abrasion layer 12 to form a protective layer 22.
The second spreading step 21 is performed by applying a quantity of polymeric composition such as to leave on the substrate 1 from approximately 20 to approximately 50 g/m2 when dried of polymeric resin, from approximately 5 to approximately 30 g/m2 when dried of cellulose fibres and from approximately 5 to approximately 30 g/m2 when dried of particles and/or fibres of material with high hardness and low abrasiveness.
Advantageously, the cellulose fibres used have a mean length of below approximately 100 μm and preferably below 50 μm and mean thickness below approximately 50 μm and preferably below approximately 20 μm.
The material with high hardness and low abrasiveness is preferably glass and advantageously consists of glass spheres or microspheres having mean diameter of between approximately 10 and approximately 500 μm and preferably between approximately 30 and approximately 100 μm, and/or glass fibres with diameter of between approximately 10 μm and approximately 500 μm and preferably between approximately 10 μm and approximately 300 μm.
Also the second spreading step 21 can be performed with a spreading machine of any known type, for example by means of a roller coating assembly, in particular by means of a reverse spreading system, or by means of a Meyer bar, or again by means of a flat-head spreading machine.
According to one embodiment, the first and second spreading steps 11, 21 are performed simultaneously by means of a flat- head spreading machine with two delivery slots, via which the first and second polymeric composition are applied respectively, one on the other, to form the anti-abrasion layer (which is deposited directly on the face 2 of the substrate) and the protective layer 22, which is deposited above the anti-abrasion layer 12. In this way, the spreading steps 11, 21 are still distinct, since they produce respective separate overlapping layers 12, 22, but are performed simultaneously by means of one single spreading machine, with considerable advantages in terms of simplicity, rapidity and economy of the process•
The substrate 1, provided with the layers 12, 22, is lastly dried in a drying step 23 and cooled and cut or wound in reels for further processing, in particular for a lamination step to form a flooring laminate.
