The present invention concerns the use of hardboard medium density (MDF, further SRP) or high density (HDF, in further PVP) for the manufacture of floor panels having a core of the SRP or PVP, a stabilizing layer, and optionally a protective layer, and it is advisable to avoid the use of the decorative layer, in other cases it is usual for flooring from laminate. In addition, the present invention relates to floor panels, which are manufactured using SRP or PVP according to the invention, as well as a floor covering, comprising a floor panel according to the invention.

Wooden floors and floor coverings of similar wood materials are becoming increasingly popular in the industry. To the dissemination of these types of floor coverings has led, in particular, the introduction of so-called connection Click ("click"), which can be stacked, for example, a laminate or parquet Board, without spending a lot of time and without the need for complex equipment. In the General case, the cheapest option is laminate.

Typically, the laminate consists of four layers: the core of PVP or the SRP, a stabilizing layer on the lower side, decorative surface papers with the upper hand, and so-called opaque film, which is abispell coating with high resistance. As a decorative surface papers use the paper with the print, usually imitating the structure of wood, such as beech or maple, or opaque materials, sealed with a solid color. Paper imprint impregnated with melamine resin and combined with the core forming, together with the covering film and roll paper, also impregnated with resin under high temperature and pressure. Using the direct coating four layer, a stabilizing layer, the core, the decorative paper and opaque film - pressed in a single step.

There are panel laminate having painted the core, intended to indicate moisture resistance. These panels also have decorative paper, and the coated core after laying is not visible.

Despite variations in decorative paper, with the impression of resemblance with wood, laminate differs from natural wood as flooring, for example, in the sense haptic or electrostatic charge. This difference is also visible in case of damage flooring. If the damage is not only superficial, but affects the decorative layer, located under the protective layer, the damage is almost impossible to fix, unless completely replace the damaged item.

Objectives of the present invention is it's easy to laying the floor covering, the treatment of which is extremely similar to natural wood, which to the touch (haptic) produces the same impression that natural wood, and which is capable of withstanding surface damage, i.e. damage should not immediately evident, and must be able to troubleshoot them without replacement. The cost should not exceed that of conventional floor coverings.

This problem is solved using PVP or SRP for manufacturing floor panels, which at one longitudinal and one transverse sides is equipped with a groove, and in each case on the opposite longitudinal and transverse side appropriate to the groove of the comb and including

A - core PVP or CPPS and

In - stabilizing layer from the bottom side,

moreover, the presence of a decorative layer is excluded.

In accordance with a special form of execution of the invention it is expedient to exclude the presence of a decorative layer, which is added to the floor panel in the form of a colored or printed paper or coating material. According to the present invention is also advisable that the application of the decorative layer by a full-scale application of the imprint on the core so that the core was covered entirely, was completely excluded.

In another preferred fo the IU execution PVP or SRP, used as a core And painted.

Also the preferred form of execution in which the floor panel includes a transparent protective layer on the upper side.

Fibreboard PVP and SRP are materials based on wood, with all three directions very homogeneous structure, so they respond well to treatment and have an attractive appearance. SRP and PVP can be processed as well as natural wood, for example, sawing, milling, drilling; as in the case of natural wood, it is possible to treat the edges and forming profiles. They have mechanical properties that are very similar to those of natural wood.

Particularly suitable rejection of the use of the decorative layer. Structure and properties of the plates of the SRP and PVP used as the core And or applied, if necessary, a protective layer To define the surface of the floor panels according to the invention. Thus, the flooring panels according to the invention is much more like to the touch wood than conventional laminate. The surface of floor panels according to the invention, which includes PVP and SRP, can be treated as parquet, waxing and varnishing. Because the core of the SRP or PVP has this extremely homogeneous with what ructural, and the surface, therefore, is not different from beneath her layers - unlike conventional laminate with a decorative layer - surface damage in case of floor panels according to the invention practically does not catch the eye, and, as in the case of wood, it is easy to fix. The homogeneous structure of the SRP or PVP also implies that the floor panels according to the invention is very easy to give a three-dimensional structure, for example, by milling or stamping. By avoiding the application of the decorative layer in the manufacture of floor panels according to the invention is obtained an additional benefit.

If the core And apply colored SRP or PVP, there are a variety of additional features decorative floors with floor panels according to the invention. So, you can combine panels of different colors, and with proper selection of dye components is also possible interesting color options, such as "marble" panel.

A wide variety of colors and effects of floor panels according to the invention allows an original way to decorate floors. Since the floor panel according to the invention is equipped with a groove and a crest, they are easy to lay and easy to remove and easy to install in a different location.

It is advisable that the floor panels with the according to the present invention may have a decorative layer, which usually has represented in the trading laminate. Decorative commercial layer laminate is used to cover the real core of the flooring, which consists of PVP or the SRP, and to give the floor a completely different look, for example, by simulating tile, tiles, flooring or boards. This decorative layer is typically injected into the laminate in the process of manufacture in the form of resin-impregnated paper or other opaque material, in which - for example, print or color - printed decoration. Another method of applying a decorative layer is a direct imprint on the core which fully sealed and completely cover. Conventional technologies used for styling and to protect the surface of wood or wood-based materials and are known to the specialist, such as lacquer clear lacquer, coating oils, waxing, polishing, plating azure and stain in the framework of the present invention are not considered to be a layer of decor. When using these methods is applied at least partially transparent layers that do not fully overlap processed underlying layer, such as the intricacy of the wood. The surface modified using technologies such as three-dimensional structuring of surfaces, such as milling, various stamping or machining CNC machines also is not considered on cortislim layer in the sense of this application.

According to the invention for the manufacture of floor panels as core And use PVP (fiberboard, high density HDF) or SRP (fiberboard medium density MDF). This fibre materials which are made by pressing wood fibers mixed with a binder agent, at elevated temperature.

Wood fibers are made of various well-known specialist of raw materials such as shavings (shredded) softwood released from the cortex. After various stages of transformation into a fibrous mass and grinding the fiber is subjected to fine grinding in the so-called refiner. Obtained when wood fiber is dried in the so-called pipeline blowdown (Blowline). For the manufacture of fiber boards are mixing wood fibers with a bonding agent. Such adhesive may occur in the pipeline purging, and then fiber with glue pass through a dryer where they are dried to a residual moisture content of 7-13%. You can also glue the fibers in special mixers after drying of the fibers in the pipeline purging. Possible combinations of the pipeline purging and mixers.

Before the manufacture of hardboard or during the wood fibers can be bleached.

When a chemical is otbelivanie wood fibers is the destruction of associated dye components of wood or transferring them to inactive using the oxidizing and reducing chemicals. For oxidative bleaching can be applied, for example, hydrogen peroxide, ozone, oxygen, salt halogenation acids, such as chlorides and salts of organic and inorganic perkiset, as peracetate, percarbonate and perborate in the first place, and their salts with alkali metals, especially sodium, and percarbonate and hydrogen peroxide are preferred. For reductive bleaching may apply, for example, reducing sulfur compounds, such as: dithionites, disulfoton, sulfites or sulfur dioxide, Sultanovich acids and their salts, in particular alkali metal salts, primarily sodium salts, and hydroxycarbonic acids, such as citric and malic acid. Preferred reducing agents are disulfite and sulfites, in particular hydrosulfite sodium, as well as malic acid and citric acid.

From the point of view of the engineering process, it is advisable to operate at bleaching so that continuous processing of aqueous solutions or dispersions of brighteners water dispersion of wood fibers concentration of from 5 to 40% wt. in counterflow towers at temperatures from 90 to 150°C and pressure up to 3 bar. Usually, in order to prevent decomposition of the bleach ions of transition metals, operate in the presence of complexing agents, e.g. the EDTA.

According to the present invention for the manufacture of wood-fiber plates shall preferably be of wood fibers, which were first bleaching oxidation, and then a recovery method.

It is preferable to oxidative bleaching percarbonate or hydrogen peroxide and reductive bleaching - sulfites or malic or citric acid.

It is advisable to carry out the bleaching of the fibers during manufacture of the plates. This bleach can be added to the chips in the pot pre-heating or in the digester during the stages of transformation into a fibrous mass and grinding. It is also advisable to add complexing agents.

For the production of plates covered with glue chip or fiber then fill with the formation of the Mat, if desired, pre-compacted in a cold mode and produce pressing plate in a heated press at a temperature of from 170 to 240°C.

As binding agents can be applied aminos, such as resins based on urea or formaldehyde resins with urea and melamine, as well as isocyanates, such as difenilmetana-4-4'-diisocyanate (MDI).

Preferably, the applied dyes had color, in each case comparable to one of the pigments, because thus it is possible to achieve a particularly intense staining of wood materials. You can, however, also apply dyes of different colors, which allows the use of shades of color.

In a particularly preferred form of execution of the invention, the plates of the SRP and PVP used for the core And floor panels, painted with a liquid formulation of the dye. This formulation of the dye described in detail in international application WO 2004/035276. The formulation of the dye content is t

i at least one pigment,

ii at least one dye,

iii at least one dispersant,

iv water or mixture of water with at least one water retention agent and

v if necessary, other components, the usual formulations of dyes.

As a rule, be applied formulations of dyes contain from 10 to 70 wt. -%, preferably from 10 to 60 wt. -%, the pigment.

In General, the dye is contained in the subject to application of the formulation of the dye in an amount of from 0.1 to 10 wt. -%, preferably from 1 to 8 wt. -%, in each case, relative to the pigment. Relative to the total weight of the formulation, this corresponds to quantities, as a rule, from 0.01 to 7 wt. -%, first of all, from 0.1 to 5.6% of the mass. The content of the dispersant to be applied in the formulation of dyes is usually from 1 to 50 wt%. in particular from 1 to 40 wt. -%

In respect of the dyes and pigments that can be applied in the formulation of dyes, rightly said above for pigments and dyes to be used according to the invention.

A particularly convenient to use the dispersant is a nonionic and anionic surfactants as well as mixtures of these additives.

In addition, with no less than mixed polyaki is enokido, preferably alkalisation with 2-4 carbon atoms and substituted phenyl of alkalisation with 2-4 carbon atoms, in particular oxides, polypropyleneoxide and poly(phenylethanoids), you can use first block copolymers, in particular polymers with content polypropyleneoxide and polietilenoksidnoy blocks or with the content of poly(phenylethylamine) and polietilenoksidnoy block and statistical copolymers of these alkalisation.

The basis of anionic surface-active additives, in particular, are the sulfonates, sulfates, phosphonates or phosphates.

Another important group of anionic surface-active additives form sulfonates, sulfates, phosphonates and phosphates polyethers referred to as non-ionic additives.

Other usable anionic surfactants based on water-soluble polymers containing carboxylate groups. By adjusting the ratio between the contained polar and nonpolar groups, you can find supplements beneficial for this specific purpose and a specific pigment.

The liquid carrier material in the formulation of dyes to be used according to the invention, forms water.

It is advisable that the formulation of dyes contained as a liquid phase mixture of water and Agay is the water retention. Agent water retention are, in particular, organic solvents, evaporation of which was very difficult (i.e. which typically have a boiling point exceeding 100°C), which therefore have the ability to hold water while soluble in water or can be mixed with water.

Examples of appropriate agents, water retention is polyhydric alcohols, preferably unbranched and branched polyhydric alcohols with 2 to 8, preferably 3-6 carbon atoms, such as ethylene glycol, 1,2 - and 1,3-propylene glycol, glycerin, aritra, pentaerythritol, pentity, as Arabic, adonit and xylitol, and exity, such as sorbitol, mannitol and dulcet. In addition, also possible to use, for example, dialkylglycerol, triacylglycerol and tetraalkylammonium and their monoalkyl esters (primarily 1-6, especially 1-4 carbon atoms). As examples should be mentioned diethylene glycol, triethylene glycol and tetraethylene glycol, onomatology, monotropy, monopropylene and monobutyl ethers of diethylene glycol, onomatology, monotropy, monopropylene and monobutyl ethers of triethylene glycol, dipropyleneglycol, tripropyleneglycol and Tetra-1,2 - and Tetra-1,3-propylene glycol, and onomatology, monotropy, monopropylene and monobutyl esters of dipropyleneglycol, tripropyleneglycol and Tetra-1,2 - and Tetra-1,3-prop is langille.

As a rule, be applied formulations of dyes contain from 10 to 88,95% wt., preferably from 10 to 80% of the mass. water or mixture of water and an agent of its holding. If the water is mixed with holding water with an organic solvent, in the General case, the proportion of the solvent is from 1 to 80 wt. -%, preferably from 1 to 60 wt%. phase.

In addition, formulations of dyes can contain the usual additives, such as biocides, defoamers, means preventing the deposition, and the viscosity modifier, the share of which in the General case can be up to 5% of the mass.

Formulations of dyes to be used according to the invention, can be obtained in various ways. It is advisable first to produce a dispersion of the pigment, which is then added to the dye in the form of solids or, in particular, in the dissolved form.

Recipe dyes perfectly suitable for painting wood-fiber plates of medium to high density (SRP and PVP).

Formulations of dyes to be used according to the invention, it is possible to add to the mixture of wood fibers and a bonding agent, which serves as a base plates of the SRP and PVP, in different ways and at different stages of the production process.

When using binding agents on the basis of aminos, such as resins based on urea or f is maldehyde resins with urea and melamine, formulations of dyes can be used in conjunction with a bonding agent, which is usually used in the form of a dispersion containing other additives - for example, hardeners or dispersion of paraffin, or separately from the bonding agent, causing them to wood fibers or chips before or after sizing. When used as a coupling agent of the isocyanate (MDI) formulations of dyes used separately from the bonding agent. When combined sizing the aminos and the isocyanate formulation of dyes, if desired, can be added to ameloblastoma component.

PVP or SRP, is used as the core And can be stained the same color.

Very attractive color effects can be achieved by blending fibers of different colors and their subsequent pressing. This allows to obtain, for example, boards with marbled or mottled pattern. Special effects can be achieved by multicolor staining of the plates. For example, fibers with different dyeing, you can compress layers. Such effects can also be achieved if the paint only a part of the fibers, and the other part retains the original color.

In addition, staining formulations of dyes containing electrically conductive carbon black, allows to produce electrically conductive plate PVP and SRP that, for example, may represent the integration of the EU in the manufacture of conductive flooring panels.

Floor panels produced using SRP or PVP according to the invention, contain a stabilizing layer of a Century as a stabilizing layer can be applied In all materials known in this field specialist, such as a stabilizing layer can represent impregnated with melamine resin paper, which is molded is attached to the lower side of PVP and SRP.

Floor panels produced using SRP or PVP according to the invention contain, if necessary, a protective layer, which is also called the covering film (Overlay). This protective layer can represent impregnated with melamine resin, transparent paper, which is molded is attached to the upper side of PVP and SRP. If the flooring panels according to the invention has a protective layer, a stabilizing layer, and a protective layer is preferably applied on the same stage. Before applying the stabilizing layer and, if necessary, a protective layer can be surface modification, for example, by stamping, machining CNC machines, notches or milling, to stove acquired structured surface. Thus it is possible to obtain the so-called "living surface" ("Living surfaces")is very reminiscent of the surface of natural wood. Milling can also perform in-depth cracks.

If the floor panel does not receive the protective layer in the form of an opaque film can be subjected to surface treatment of a different kind. The surface can simply be treated with polishing, waxing, cover with oil, stain, glaze or varnish. In the General case can also be applied to the floor panels according to the invention all of the methods and materials surface treatment, known from the field of protection of the parquet surface, as, for example, lacquer curing under ultraviolet light, powder coating and other transparent coatings. Before such processing can give the surface of the three-dimensional structure, for example, through various stamping, machining CNC machines, notches or milling. In another form of execution of the invention the surface of the floor panel only give a three-dimensional structure and not conduct any further surface treatment.

Floor panel according to the invention can also contain other layers. For example, on the lower side of the floor panels can be applied soundproofing or insulation.

Plate SRP and PVP, equipped with a stabilizing layer, and optionally a protective layer, divided in accordance with accepted trade sizes and equip on one longitudinal and one transverse sides of the groove, and in each case on the opposite of the longitudinal and transverse side appropriate to the groove of the comb. This can be done, for example, by milling.

The subject invention also are floor panels made by paragraphs 1-11, as well as floor coverings containing flooring panels according to the invention.
