Description

The floor be used to make the method on floor

The application is to be on December 9th, 2005 applying date, and application number is 200580041745.1 (PCT/EP2005/013411), and denomination of invention is divided an application for the application for a patent for invention on " floor be used to make the method on floor ".

Technical field

The present invention relates to a kind of floor, more specifically is a kind of laminate flooring, and the method that is used to make the floor.

Especially, the present invention relates to the floor of such type, promptly; Be intended to be used to form a kind of unsteady floor overlay, and this floor comprises decorative cover, preferably the decorative cover of printing; And based on the top layer of synthetic materials, and the imitative a kind of grain pattern of cosmetic side face mould on floor wherein.

Background technology

Known, through laminate flooring imitation wood floors parts commonly used or parquet.Known, this imitation great majority are to realize that by the floor that the decorative cover that has printing is provided this decorative cover is represented a kind of photographic image of timber.

When imitating the timber of some kind, at first be dark-coloured and/or external timber kind, such as Zimbabwe Door frame (Wenge), common technology causes not satisfied result.

Summary of the invention

Catalogue of the present invention provide novel floor, provide new possibility to realize imitation whereby.More specifically, the present invention provides solution, can realize the good imitation of dark-coloured and/or external timber kind.

For this purpose, according to first aspect of the present invention, the present invention relates to the floor; Relate more specifically to such floor, that is, be intended to be used to form a kind of unsteady floor overlay; And this floor comprises decorative cover and based on the top layer of synthetic materials, and the imitative a kind of grain pattern of cosmetic side face mould on floor wherein, and has such characteristic; The surperficial above that zone with the various luster degree that extends across upper surface, this floor, its function is the overall grain pattern of imitation.

Therefore by this overall grain pattern, the big zone of grain pattern is expressed at least, and is not only local phenomenon, such as the part between timber pore, timber corpus callosum or the timber train of thought than the deep branch.

By the grain pattern that is integrally formed by different glossiness zone, extra yardstick increases to the floor, produces new application possibility whereby, and the timber kind that consequently is difficult to imitate can be represented with mode preferably now.

Preferably, for above-mentioned zone, use two corresponding glossiness at least, they can the person of being used clearly be distinguished, that is, can be seen by naked eyes.

More specifically, preferably, use two glossiness respectively at least for above-mentioned zone, they are selected like this, make some zone clearly represent them from as matt zone, and other region representation they from zone as non-lacklustre or gloss.

It is 10 glossiness that the most matt zone on the floor preferably has, and be less than 10 better, and less matt zone or gloss zone has the glossiness greater than 10, and is greater than 20 better, all according to DIN 67530 measurements.

Do not consider the absolute glossiness used preferably to be at least 10 in the tarnish on floor and the difference of the glossiness between the gloss zone.

When laminate is when having the pressing plate realization in different glossiness zones by use by pressing process manufacturing and different glossiness zones; The glossiness of on pressing plate, measuring subsequently is preferably matt regional less than 40; Greater than 40, and is greater than 100 better in the gloss zone.

In the most preferred form of embodiment; In the position of wooden construction, upper side only has two glossiness basically, and it means by naked eyes; Normal eye height and during with suitable viewed above the floor of installing, only two visibly different glossiness can be identified.Therefore can produce the contrast clearly between the adjacent areas.Therefore the zone of glossiness in the middle of not having subsequently.

In the special shape of embodiment, decorative cover is to be formed by a kind of color or a kind of basically color, and this color is preferably dark-coloured, especially black or approximate black.Subsequently, grain pattern is only confirmed by the zone of various luster degree.Its advantage is, in this mode, only needs a kind of color basically, and can represent very dark timber.

Yet in the preferred form of embodiment, decorative cover should be formed by at least two kinds of various colors, and these colors are preferably also represented grain pattern.In other words, the floor will show two kinds of zones subsequently, and their color differs from one another.In the most preferred form of present embodiment, the decorative cover of every floor is only realized by two kinds of colors.Highly observed from normal eye generally by " two kinds of colors " meaning, two kinds of colors can be identified basically.Preferably, every kind of color is monochromatic, yet, also might form " a kind of color " by several colors.For example, in four-color process or by using color spot admixed together, they present a kind of single clear and definite color effects generally.In addition, possibly there is the sparse zone of another kind of color in crossover position place between two kinds of colors, yet the user highly can not discern from normal eye.

Be noted that when producing such floor, although can make a large amount of different floors; Not only designed patterns is different for they; And color or overall tone are also slightly different, and like this when the installation floor, the minute differences that can see about tone appears in different floors each other.

Preferably, above-mentioned two kinds of colors are different aspect following at least, and a kind of color is than another kind of darker in color.In the most preferred form of embodiment, the darkest color is black or approximate black, or dark especially color is used in this color usually.In the actual form of embodiment, use is comprised the black of dark Bordeaux purplish red (bordeaux) tone.Preferably, other color also is darker.Select brownly when this other color, especially dark-brown or when light grey can obtain especially good result.In the actual form of embodiment, this brown or light grey in preferably also comprise the rose tone.

Provide the advantage on the floor of the grain pattern that has the grain pattern that forms by glossiness and form by color to be, stand in the ground people who forms on this kind floor and almost always will observe a kind of pattern, irrelevant with the angle of incident ray.When this person leans to one side to face toward the floor of his front of incident ray observation, he will seldom maybe can not distinguish the pattern that is formed by color, but he will clearly distinguish the pattern that is produced by different glossiness owing in the reflection of synthetic surfaces glazed thread.Yet when looking at straight or almost looking at the floor straight, if the incident ray of inclination is only arranged, he will be difficult to see the pattern that is formed by different glossiness, but he will distinguish the pattern that is formed by color region.

According to the important preferred form of embodiment, different glossiness zone and various colors zone be correspond to each other or correspond to each other basically.Be noted that in conjunction with this point and can clearly distinguish different glossiness when having such angular light line reflection, matt part is regarded as than shallow portion basically, and this probably can use the diffuse scattering of light to distribute and explain.By having matt zone corresponding to regional than light colour; The result who obtains is; When changing to a kind of viewing angle of environment or direction of observation; The difference of color becomes and can distinguish here, and the difference of glossiness becomes not too and can distinguish, then will can not observe the unexpected conversion of " light areas ".

An instance of having a mind to change at last is to make the zone of clear and definite glossiness be a bit larger tham the zone of accordingly clear and definite color.Confirmed in test to get rid of some the undesirable compensating action that makes last image shinny whereby.

The particularly advantageous combination of characteristic is; On the one hand as previously discussed, use two kinds of colors that differ from one another, and wherein a kind of color is more of light color than another kind of; And on the other hand, the zone of glossiness that has the most matt effect that causes is corresponding to by the zone that forms than light colour.For definition, be noted that by a kind of " more shallow color " it is to make a kind of color more of light color wittingly, yet this does not mean that this " more shallow color " must be light tone than another kind of.As previously discussed, this color even also preferably darker, for example brown, and be than dark-brown or light gray better.

According to the above, be noted that light reflects under such angle, that is, different glossiness can be observed well, matt part is rendered as than shallow portion basically, and this probably can use the diffuse scattering of light to distribute and explain.Now by having matt zone corresponding to dark areas more not; The result who obtains is; When changing to a kind of viewing angle of environment or direction of observation; The difference of color becomes and can distinguish here, and the difference of glossiness becomes not too and can distinguish, with the unexpected conversion that can not observe " light areas ".

In the most preferred form of embodiment, make matt zone greater than the above zone that forms than light colour, thereby it is overlapping that edge is had, matt whereby zone extends into the fringe area than dark areas.

Preferably, each in turn be smooth for said different glossiness zone, but in bigger matt zone except the possible meticulous matt structure, and except the possible local relief, for example in order to imitate the relief of timber pore.Therefore preferably be excluded such as being positioned at the coarse structure of going up in order to the rib of imitation timber train of thought on the surface.Because therefore the coarse structure in each zone is excluded basically, so avoided being weakened by the pattern that various luster degree zone forms, this weakening possibly produce adverse influence to expected effect.

Two kinds of zones, the gloss zone preferably has common surface roughness less than 1 μ m Ra with matt zone, gets rid of because the possible unevenness of imitation timber pore.

According to the preferred form of embodiment, said different glossiness zone is in the identical plane basically, therefore on identical height.More specifically; Preferably said different glossiness zone is by suppressing with identical pressing plate; And these zones are positioned at identical plane, exception be possible difference in height, this difference in height only derives from such fact; That is, a matt structure has been arranged on corresponding position on the pressing plate.Common this matt structure is the local shot-peening by pressing plate, forms such as sandblast.

When at all events there was difference in height in reason between said different glossiness zone, it was preferably less than 0.01mm, even was less than 0.005mm better.

In fact do not have difference in height to be used, or minimum difference in height only arranged, of before this, the advantage that provides be do not have to see or almost do not have visible difference in height itself to manifest, when vertically or almost vertically observing this floor downwards, this is favourable.In most practical application, each regional tarnish accordingly and less lacklustre structure are to be difficult to distinguish from such viewing angle.Owing to there is not the difference in height of essence, therefore there is not transition to be perceiveed, as its result, decorative cover is not by disturbance.This point is even more important under the situation of using different glossiness zones and various colors zone, makes matt zone be a bit larger tham its corresponding color region thus.If the main difference in height that forms Transition edges is arranged in the case, they can be seen from closely being seen subsequently especially, they not with each color between transition accurately overlap, this can be rendered as disturbance.

When difference in height is excluded or is restricted to hour, the advantage of generation is that the pressing plate of requirement can be realized with better simply mode.

Yet the above can not get rid of to still have possibly provide bigger difference in height wittingly, for example, in order to produce special effect, or is considered as less important when described shortcoming.

On the upper surface on floor, also can have relief to exist, it imitates timber pore.In such cases, preferably these reliefs are corresponding to wood structure, and this is the technology of called after " fit (registered) relief ".

As previously discussed, the present invention provides a kind of technology, and it is particularly useful for imitating dark-coloured timber variety, does not wherein almost have colour-difference to be distinguished, so this brand is difficult to imitate by the decorative cover that uses printing with normal mode individually.According to idea of the present invention, by using the overall wood grain structure of representing with different glossiness, might obtain good imitation really, also use different colours but this imitation is improved in corresponding zone.

In practical application; Therefore the present invention will be used in imitation Zimbabwe Door frame (Wenge) kind, thus the grain pattern that certain use can be compared with the Zimbabwe Door frame, and that derive or duplicate from true Zimbabwe Door frame even better grain pattern; For example; By self known reproduction technology, therefore for example, the pressing plate of preparing to use is based on the etching of photocopying technology.

Though the present invention shows the advantage when especially imitating Zimbabwe Door frame (Wenge), it also is highly suitable for imitating some other wood and plants, and especially external wood kind.Because the engineering feasibility that provides by different glossiness preferably combines with various colors, can obtain good especially imitation so have.

Be noted that when using different glossiness imitation grain patterns, particularly advantageously be to use the bigger tarnish that replaces regional, especially when the pattern structure of the so-called timber of these region representations with gloss zone and/or various colors.

Preferably, every floor should have continuous wood structure separately, or in other words, every floor should be represented the imitation of an independent single-piece sheet material.Yet,, do not get rid of several sheet materials, band, web or other etc. and appear on the independent floor according to a kind of remodeling.

The laminate that is provided with dark decorative layer often has such shortcoming, that is, after it is installed, between the floor, have the slit of tangible light color to see.This is a cutting top layer when being shaped, and more specifically says so because the result of the milling at edge.Through the cutting top layer, the cutting of change or paper that possibly produce the resin reflection index is more obvious.For fear of possibly producing of this light slit; Can use the top edge of a kind of color to carry out painted if desired on the floor; Its tone is preferably corresponding to the overall tone of decorative cover; Perhaps at the lateral edge height place of top layer a kind of colorant being set at least, perhaps removing the material part at top edge height place, is a kind of color thereby make the surface of formation.

On principle; The present invention can be used in the laminate flooring of any kind, and this floor has the decorative cover and the laminate layers of synthetic materials, with the location independent of decorative cover with respect to laminate layers; This floor is made up of synthetic materials, and how to realize with the laminate layers that synthetic materials is formed and constitute irrelevant.

Yet, not restriction basically, the present invention in fact is intended to be used for the laminate flooring of such type, and it forms by compacting plate of lamination, more specifically, is used for so-called direct pressure lamination (DPL) type floor.

Yet the present invention also can be used for the floor of other type, and for example, laminate layers is made up of high pressure lamination (HPL), and so-called compact lamination.

Especially, the invention is intended to be used for laminate, this laminate has the top layer of thermosetting resin, more specifically, and the thermosetting Melantine.

Preferably, decorative cover is made up of a kind of printed matter, and it is printed on the carrier, for example is positioned at the ply of paper of synthetic materials top layer, such as when realizing direct pressure lamination, high pressure lamination or compact lamination, doing so usually.Yet, do not get rid of from alternate manner yet and realize printed matter, for example, by directly it being printed in the following basic unit, by or not by the intermediary of bottom, sealant or other similar item.

Be noted that the layer that coloring material that " decorative cover " is interpreted as applying by any technology is in a broad sense formed.Thus, it possibly be for example by the material of traditional printing technology printing, and by printer, how the printed matter that forms of digital printer for example, and by colorant, paint, China ink, or the layer that forms of other hardening material apply regardless of these products.

According to modification of the present invention, replace said decorative cover to use painted laminate layers.Comprise at laminate layers and can use coating paper under the situation of for example imbedding ply of paper wherein, in other words, wherein colorant has added in the paper when the production of paper, perhaps wherein uses the colorant impregnated paper.In addition, also can use painted synthetic materials, for example painted resin.

Be noted that under the situation of using the various colors zone, as previously discussed, preferably extend according to grain pattern.Do other possibility of not getting rid of color gamut like this.Therefore for example, decorative cover can be provided with dot pattern, and for example, black and other look are such as brown merging point; Perhaps for example be provided with black background, have the spot of other color therein, like this, for example as monochromatic, such as the replacement of black, decorative cover, therefore different subsequently glossiness zones is realized with the form of grain pattern, and is not corresponded to color pattern.

According to the preferred form of embodiment, have on the floor under the situation of concealed installation facing, be the material layer of low key tone yet also on this decorative cover, use transparent, so decorative cover obtain fuller tone.By using so painted material layer, when this decorative cover comprises China ink or other similar item, no longer very good hiding power need be provided.Good hiding power is a problem for dark color sometimes, the material transparent layer by using painted on the decorative cover top, and this problem is excluded now or reduces.

Bepainting material layer can be realized in a different manner.

On the one hand, before made on the firm and hard border that forms the floor, colorant can mix with said synthetic materials itself, and promptly normally used Melantine is for example arranged in the resin.By this way, laminate layers itself will play the effect of bepainting material layer.

On the other hand, on the top of the decorative cover that prints, exist under the so-called cap rock situation, the carrier material of cap rock also can be painted material, for example, paper, the dark-coloured colorant of some adds wherein.As known, as the result of compacting, the paper of cap rock becomes transparent.Yet the colorant that is present in wherein keeps and can see, so that produce transparent bepainting material layer.

Should also be noted that the described region surface summation in every kind of zone preferably covers the major part on the whole surface on floor, and preferably cover 25% of its surface at least.

For clear, the total surface of the Zone Full of the glossiness that therefore for example its meaning is certain with, on the one hand all the total surfaces in matt zone with, and on the other hand at every turn should be less than 25% of whole surface, floor than the summation of gloss zone all surfaces.

Be noted that such decorative cover can be made up of many layers.About dark color, for example, preferably, at first form bottom in order to construct decorative cover, on it, be provided with after this and decorate China ink or other material.

Obviously, as previously discussed, the top edge on the floor carries out painted any laminate flooring that goes for, and for example, in order to cover the undesirable effect of seeing in gap position place, two floors are adjacent to each other herein, tangible as previously discussed light slit.According to second independent aspect, the invention still further relates to a kind of floor, wherein the floor comprises decorative cover, and based on the top layer or the laminate layers of synthetic materials.Therefore this floor is provided with coupling part in two relative sides or edge at least; Allow two such floors to be fitted to each other in these sides; And therefore this floor in the above side; The top edge that when two such floors are fitted to each other, is used to be adjacent to each other in the above top layer or laminate layers position display, and it is characterized in that, said top edge are painted on the height of the transverse edge of laminate layers at least.

Mean herein by " adjacency "; For the user, can find out that at first sight the upper surface on corresponding each floor abuts one another together, in fact this do not get rid of possibly exist limited intermediate gaps between two top edges; For example; Less than 0.5mm, for example be the result of production tolerance, such as intermediate gaps as the parallelism of side or the not enough result of straightness accuracy.In other words; The floor that relates to does not like this have special setting in their upper edge; Therefore when two such floors during each other mutually by installation; Can find out that one is created on the floor surface of acquisition with recessed joint clearly with intentionally, for example, the recessed joint that in being provided with of chamfering etc. or two floors, obtains.

According to second aspect, the present invention is specially adapted to scenario, that is, when the top layer of laminate layers substantially perpendicularly cuts at said upper marginal position place, for example, accurately vertical or have minimum incision with respect to the plane on floor.About having the floor of such perpendicular cuts top edge, the above light slit great majority subsequently presents serious disturbance, and when with suitable color dyes, this shortcoming can be remedied or minimizing at least.

Preferably, the floor is a rectangle, on two pairs of opposed edges or side, shows top edge in the position of said top layer or laminate layers, this top edge at least on the height of the transverse edge of laminate layers by painted.Yet, painted carrying out that might be such in second pair of upper edge on floor, and/or take other measure in these edges, so that limit or avoid the generation of undesirable visual effect; Therefore, for example, chamfering etc. can be formed on corresponding upper edge, and this top edge is provided with color layers or other decorative layer.

In the especially preferred form of embodiment, the floor is a rectangle, and its two short sides, shows top edge in the position of said top layer or laminate layers, and this top edge is painted, and covers with decorative layer two long side surface place chamferings.

By above-mentioned can be clear and definite, other various painted in, this kind be painted can be applicable to the floor that shows first aspect characteristic of the present invention.

According to its second aspect, the present invention also is applicable to the floor especially, the stone material of the imitative slabstone of its cosmetic side face mould or other sheet shape kind, and therefore its upside has the step relief.Be interpreted as relief on equidirectional downward or upward by " step relief ", between continuous basically relief or step, show two-stage transition at least.Owing on the top edge on this floor, possibly have this kind relief, the difference in height in the overlay of floor between the adjacent floor might produce, if do not use second aspect, it will especially cause the visibility of the increase in said tangible light slit.

Yet, can be clear and definite, the present invention according to its second aspect also applicable to other floor.Avoiding undesirable visual aspect all is favourable for any floor overlay.Therefore, the present invention also is applicable to other floor that shows outside the first aspect characteristic, and it also be applicable to the decoration side of the stone material that has imitation slabstone or other sheet shape kind and therefore its upper surface have other floor of step relief.The present invention also can be applied to, and for example, does not have relief and/or the surperficial floor that is provided with low in glossiness above that, or is applied to the floor by their decorative cover with printing relief imitation fragment timber.

The present invention is intended to be used to have the floor of direct pressure lamination (DPL) or high pressure lamination (HPL) type laminate layers or top layer especially, is adjacent to each other undesirable visual effect at gap position place of position subsequently by said painted and by being covered at two floors whereby.

Can be clear and definite; The present invention is favourable especially for any floor that is provided with dark-coloured decorative layer; For example for the floor of imitating such as the natural dark-coloured wood of Zimbabwe Door frame (Wenge), Jatoba (Jatoba) etc. is planted, dead color is painted wood kind, dark-coloured stone material kind etc.; As previously discussed, the slit of light color will manifest with the mode that worsens.Yet, can be clear and definite, the present invention is not limited to the floor that is provided with dark-coloured decorative layer according to second aspect.The invention still further relates to the floor of the decorative layer that is provided with light color, for example, imitate the floor of the wood kind that natural light color wood is planted, light color paint is handled, the stone material kind of light color etc.

According to the possible form of embodiment, painted tone is corresponding to the overall tone of decorative cover and/or at the tone of the position, fringe area on floor decorative cover.Do not get rid of like this and can use any other painted tone, thereby play the effect of hoping effect.

In the preferred especially form of embodiment, this tone is deeper than the overall tone of decorative cover, or is deeper than the overall tone at the decorative cover of the edge on floor at least.Therefore, for example, adopt a kind of darker colorant; Such as black, be used to have painted than the top edge on the floor of thin shade decorative cover, help in the overlay of floor stressing of floor separately; Cause the more natural outward appearance of floor overlay like this, it is made up of some so painted floors.Be noted that covering of undesirable visual effect described here relates to by making it in the overlay of floor, be shown as dead color or black and cover white gaps, present less disturbance like this, and in some cases even more natural than white gaps.

In another preferred form of the embodiment of second aspect of the present invention, painted tone is corresponding to the tone of the timber pore of representative on the decoration side on floor.Therefore, for example, the floor that imitation seal eggplant wood (Merbau) is planted preferably, is provided with dark-colouredly, and painted such as black is because the wooden hole of these timber varieties also is shown as dead color or black on the whole, rather than more shallow painted timber.

This painted can carrying out with any way for example, is used felt tip pen, yet, preferably carry out with the sclerosis colorant, especially dry colorant, colorant provides with liquid form, and is hardened subsequently, for example, can use China ink, paint or pigment.

In the preferred especially form of embodiment, painted is that colorant is sprayed, is injected in the result on the top edge, and preferably includes the printing of being undertaken by the ink-jet printer feed system, and its assurance flexibility and/or firm is painted.Injecting coloring agent or ink-jet by ink-jet printer or similar machine produce can be controlled with plain mode, therefore can in the automated production process, use best.Be noted that said injecting coloring agent comprises any type of injection, on injecting coloring agent to the surface to be colored, therefore this injection can comprise the continuous injection of particle, drop and the liquid of atomizing whereby.

In other preferred form of second aspect embodiment, use painted has special characteristic; Therefore, for example, it can have waterproof characteristic, anti-attrition characteristic, adhesive characteristics, antistatic characteristic etc.Said antistatic characteristic can make on the floor top layer of crossing whole floor overlay or the inner easy loss of electric charge that produces.Said anti-attrition characteristic can increase comfortableness when the floor overlay of being made up of this floor is installed, for example, when installing and/or dismantle the floor overlay, might and/or must relative to each other move the floor.

According to the 3rd independent aspect, the purpose of this invention is to provide simple and/or cheap and/or flexible method, be used to make the floor, this floor for example, shows the characteristic of second aspect.For this purpose; The present invention relates to be used to make the method on floor; Wherein this floor comprises decorative cover and top layer or the laminate layers based on synthetic materials; And this floor is provided with coupling part in two relative sides or edge at least; Allow two such floors to be fitted to each other, it is characterized in that at these edges, this floor one or more upper edge be provided with in top layer or laminate layers position at least by the ink-jet printer feed system hardening material is injected on these top edges and form painted.

By " ink-jet printer feed system " at first is a kind of feed system of meaning; Produce the drop of the above material by it; And these drops are charged by static ground; In any case skew under the influence in magnetic field is the corresponding top edge on floor at receiver media in such cases when moving into the direction of receiver media.Such system is known as the system that is used on the trailing flank that is printed on the floor such as the data that produce data.Certainly, also might use ink-jet printer feed system according to other possible principle work.

Such ink-jet printer feed system allows, and for example forms the mist of ink droplet, thereby makes the top edge can be by painted, and the for example decoration side on floor that do not need protection basically.Make the possibility of spraying skew of generation that the possibility that can be used on a large amount of uses useful in the production on floor by identical feed system is provided by the ink-jet printer feed system.

As previously discussed; The ink-jet printer feed system can be with easy mode automation; And according to the 3rd independent aspect; Use this system to cause flexibility and/or inexpensive method, be used to make the floor of surface finish preferably, especially less or do not have a floor of undesirable visual effect in the overlay of floor.

Preferably, China ink is used in said hardening material, and it causes the painted of thin layer, for example, even, also will never hinder the connection on corresponding floor if corresponding top edge is used to be adjacent to each other wittingly.

According to a kind of possibility, this method is applicable to the floor, and its top layer or laminate layers substantially perpendicularly cut with respect to the floor level at said upper marginal position.

According to another kind of possibility, this method is applicable to the floor, and it on top is provided with chamfering etc. in the edge place, and wherein the surface of chamfering is to use said material painted basically, such as, according to the third aspect, by said ink-jet printer feed system.

In the above two kinds of possibility; When providing said when painted, preferably use the ink-jet of moving or the injection of another kind of material; And direction is controlled like this; Thereby make strip expediently top edge to be colored when the operating area that clearly limits moves, make to spray to cover this operating area that clearly limits, acquisition is with the good covering of said material to corresponding top edge like this.

The present invention is especially favourable for such floor, and its top layer or laminate layers are direct pressure lamination (DPL) or high pressure lamination (HPL) type, thereby makes two floors be adjacent to each other undesirable visual effect of position by said painted being covered.

Should not get rid of to be used for forming in identical upper edge and paintedly use two or more to spray simultaneously, these spray and preferably derive from different inkjet printing feed systems.These injections preferably are based upon different angles, thereby obtain the good covering of corresponding top edge.

The specific embodiment

Shown in Fig. 1, the present invention relates to the floor 1 of the type that is intended to be used to form unsteady floor overlay among others according to its first aspect.

Shown in Fig. 1 and 2, floor 1 is preferably at least at two opposed edges 2-3 places, and preferably is provided with coupling part 6-7 at two couples of opposed edges 2-3 and 4-5 place, can be coupled to each other by many this floors 1 of this coupling part 6-7.As shown in scheming, these coupling parts 6-7 is such type preferably, in the locking that is being implemented under the coupled situation on floor 1 on vertical and the short transverse.According to each remodeling, do not get rid of the coupling part of other type, for example, the coupling part of normal tongue piece and form of grooves or be used to realize the coupling part of so-called " falling into formula " connection.Coupling part need not manufacture one with floor body.Might be at the coupling part of the paired edge's combination several types of difference.The possible instance of coupling part especially can be known by following patent: WO 97/47834, and WO 01/96688, and WO 01/96689, and WO 01/98603, and WO 96/27719, and WO 00/20705, and WO 00/47841, WO98/58142 and JP 07-300979.

As shown in Figure 3, floor 1 comprises decorative cover 8 and a laminate layers or top layer 9 based on synthetic materials 10 of at least one printing, and a underlying basic unit 11.

Shown in instance in, laminate layers 9 is direct pressure lamination (DPL) types, and for this purpose, it is by compacting two-layer and constituting each other on underlying matrix 11; First floor just, the called after decorative layer 12 hereinafter, and this decorative layer 12 is to be made up of the carrier that is perfused with synthetic materials 10 13; More specifically, this synthetic materials is a resin, for example; This carrier is a paper, and decorative cover 8 is with form settings such as printings in the above, and the second layer; Just so-called cap rock 14, for example it also is to be made up of the carrier that is perfused with synthetic materials 10 15, more specifically this synthetic materials is a resin.When most of, carrier 15 is made up of pure paper, when compacting, becomes transparent.The material that increases the abrasion resistance of final laminate layers 9 can add cap rock 14 in a known manner.

Certainly, laminate layers 9 is decoration side or upper side 16 places that are positioned at floor 1.Shown in Fig. 2, a common backing layer 18 will be arranged on the downside 17 on floor 1, and this backing layer also is to be made up of laminate layers.

The floor large-scale laminate of 1 usefulness is made in a known way, and this large-scale laminate is floor 1 by sawing, after this, for example by a series of milling process, forms the coupling part of for example said coupling part 6-7 in the edge on floor.

The manufacturing of this laminate, for example as shown in Figure 4, be by in hot press 19 at high pressure pressed different combinations layer, therefore for example, decorative layer 12, cap rock 14 and backing layer 18 are compressed on the matrix 11, thus and sclerosis.The structure of the upper surface of plate, therefore and also have the upper side on floor to depend on the structure of the contact surface 20 of the pressing plates 21 that use in the press 19.The known better called after of this pressing plate 21 " platen ".

First aspect of the present invention is characterised in that, shown in Fig. 1, floor 1 side 16 above that illustrates the regional 22-23 of the various luster degree that extends across upper surface, presents the form of grain pattern generally.These regional 22-23 can clearly describe by shadow region and nonshaded area in Fig. 1, and wherein the zone 22 of the first clear glossiness is represented to have in the shadow region, and nonshaded area representes to have the zone 23 of obvious various luster degree.More specifically, zone 22 is represented in the shadow region, and this zone is visible as matt zone for naked eyes, and nonshaded area is than gloss.

Though, do not get rid of and use the zones of different that surpasses two kinds of mutual various luster degree, preferably, shown in Fig. 1, exclusively use the only regional 22-23 of two kinds of clear and legible other glossiness.Therefore, be intended to make by naked eyes when the floor 1 top normal eyes height of installing is observed, only can distinguish two kinds of visibly different glossiness.

This different glossiness can realize in any manner.Yet, preferably, for this purpose, using pressing plate 21, this pressing plate is as shown in Figure 4, is provided with contact surface 20, and this contact surface also has the regional 24-25 of various luster degree.The zone 25 that has high gloss is level and smooth basically, and the zone 24 that has a minimum glossiness has careful non-flat structure 26, and this structure is for example by the blasting treatment pressing plate 21 and obtaining for example of shot-peening on the height in zone 24.Therefore after the compacting, in zone 22, careful non-smooth structure 27 is retained in the upper surface of plate of compacting, shown in Fig. 3.Visually, this non-smooth structure 27 provides matte performance.Because careful non-smooth structure 27, the reflection of light in fact takes place with the diffuse scattering mode, thereby produces more lacklustre outward appearance.

Be noted that the compacting of using careful non-smooth surface in order on the forming board that is shaped, to keep the technology of mat surface, is known in the prior art.

According to any one in the possibility of first aspect of the present invention described in introducing, floor 1 has decorative cover 8, and this decorative cover is made for a kind of color or a kind of basically color, is preferably a kind of dark color.Meaning for example in Fig. 1, does not observe color pattern, and only has the pattern that can see to be to use the result of two kinds of glossiness on upper surface so subsequently.Therefore the color of decorative cover 8 is preferably black or appears as approximate black.

In Fig. 5, the part of the upper surface of the preferred variant on schematically illustrated floor 1 according to first aspect of the present invention, yet; Wherein decorative cover 8 is made for two kinds of various colors; In other words, decorative cover 8 has two kinds of regional 28-29, and their color differs from one another.More specifically, in the embodiment of Fig. 5, the regional 22-23 of various luster degree and the regional 28-29 of different colours are corresponding each other.

How upper surface portion shown in Fig. 6 and 7 illustrates in Fig. 5 constitutes.

Fig. 6 illustrates regions of different colours 28-29, as schemes interior finding, and these regional 28-29 also represent grain pattern.The mutual difference of these two kinds of colors is that a kind of color is darker than another kind of color, and therefore the darkest color is preferably black, and more shallow color is brown or light brown.In Fig. 6, the zone 29 that constitutes with dark colour is plotted as and has shade, and the clear area in the figure is represented by for example by the brown zone 28 that constitutes than light colour.

Fig. 7 illustrates in order to the various luster degree zone 22-23 corresponding to Fig. 6 part.Be noted that at this zone 22 that in Fig. 7, is depicted as the glossiness that provides maximum matte performance having of shade and the zone 28 that in Fig. 6, constitutes for the blank color by more shallow correspond to each other.The grain pattern that " corresponding " meaning is identical, approximately uniform grain pattern or the grain pattern that extends in the same manner generally are used to the zone of different colours and various luster degree.Moreover, preferably whereby also meaning on the one hand regional 22-23, regional 28-29 is in corresponding position with respect to bigger zone at least on upper side on the other hand; In other words, the grain pattern that produces by glossiness and by the grain pattern that color produces on end face, correspond to each other ground or approximate location accordingly.

Skew is not got rid of wittingly or by mistake existed to above-mentioned way.So for example, preferably, shown in Fig. 5 to 7, make matt zone 22 or at least its major part greater than by the said zone 28 that constitutes than light colour.This meaning, the width B 1 than light colour zone 28 of same position shown in the width B 2 in the corresponding matt zone 22 shown in for example in Fig. 7 is a bit larger tham in Fig. 6.Thereby produce overlappingly 30 at the edges in two zones, therefore matt zone 22 extends into the fringe area of dark color region 29.This is overlapping can be several millimeters.

Can obtain by providing matt zone 22 to extend to be slightly wider than corresponding color region 28, if for example, by the extension of carrier 13, minimum mutual skew between zone 22 and 28 still can obtain zone 28 by the good covering in zone 22.Test shows, can reduce undesirable flash effect by this way.

In the more preferably form of embodiment, relief 31 also is arranged on the upper surface on floor 1, in other words, in decorating side 16, said relief imitation timber pore, it is preferably corresponding to said grain pattern.In the cross section of Fig. 3, schematically illustrated several such reliefs 31.Obviously, can realize by pressing plate 21 processing, on this pressing plate, have essential bossing 32 like these reliefs shown in Fig. 4.

The top view of schematically illustrated this line pattern confirmed by relief 31 of Fig. 8, with respect to the surface portion shown in Fig. 5 to 7, and the schematically illustrated final effect of Fig. 9, Here it is has used pore structure on the surface of Fig. 5.

By " corresponding to " relief of said grain pattern, meaning relief 31 is to set up according to imitation grain pattern or the pattern that more or less imitates grain pattern.As for real timber, timber pore needn't imitate the obvious zone of different colours.When imitating floor 1 according to the present invention, yet, preferably make the relief 31 of imitation timber pore be positioned at matt zone 22 substantially, as shown in the figure.

For integrality, being noted that in Fig. 3 and 4 each layer and surface texture and therefore also having relief 31 is to represent with the mode of simplifying greatly.In fact, top layer or laminate layers 9 for example only have the thickness of 0.15mm, and the thickness of relief 31 needn't be restricted to the thickness of cap rock 14.

Be noted that not get rid of various luster degree zone 22-23 is combined with the relief 31 of imitation timber pore, and do not use various colors.Like this, for example mean that the various luster degree zone 22-23 of Fig. 7 combines with the pore structure of Fig. 8, yet be in natural painted substrate that this substrate is for example by dead color, monochrome, especially black decorative cover 8 constitutes.

Shown in Fig. 3; Zone 22-23 is preferably such for said various luster degree; They upper surface each be followed successively by smooth or substantially flat; Except the possible careful matt structure 27 in matt regional 22 positions, and possible local relief, except the said relief 31 of imitation timber pore.

Said various luster degree zone 22-23 can be positioned in the substantially the same plane, therefore is in an identical height or approximately uniform height, and different height.

Yet shown in Fig. 3, various luster degree zone 22-23 preferably is positioned in the substantially the same plane, therefore at identical or approximately uniform height, only depends on except the possible difference in height of roughness of structure 27.In fact the advantage that between regional 22-23, does not have or almost do not have difference in height to provide is discussed in introduction, does not have the real Transition edges that rises to be observed, and is excluded as the disturbance factor of its possibility of result.

Especially, seeing generally preferably that possible difference in height is less than 10 μ m, is less than 5 μ m better.Under for the unevenness situation that produces matte performance, the difference in height of expection is the vertical drop between the upper side of higher point and less tarnish or gloss adjacent area 23 of peak value of uneven structure 27.

Yet the above also is not precluded within some purposes, with using bigger difference in height.

According to first aspect, the present invention is applicable to the dark-coloured hardwood kind of imitation especially, though do not get rid of the purposes that is used for other imitation.In first instance, be to be used to imitate Zimbabwe Door frame kind wittingly.For more clearly demonstration, the part of the real printed patterns of the laminate flooring that is used for manufacturing imitation Zimbabwe Door frame (Wenge) is shown in Figure 10.Herein, that darker part is represented is dark-coloured, black region 29 preferably, and blank parts is represented than light colour zone 28.Matt attached pattern with the gloss zone will constitute in an identical manner, so the white space in Figure 10 representes matt regionally 22, and the possible difference that only has is with use described overlapping 30.Figure 11 illustrates the true swelling structure that is used to imitate timber pore with Figure 10 coupling.

When forming above-described floor 1, the edge 2-3-4-5 that especially on forming the floor, exists is during with coupling part 6-7, through the cutting of being everlasting advance through top layer, in other words, laminate layers 9 such positions set up light especially white edge line.The result that the reflection index of this chances are synthetic materials 10 changes, this result causes synthetic materials to become white, rather than transparent.Another kind of hypothesis is that at least for direct pressure lamination (DPL), white edge becomes and can see when the carrier 15 of the carrier 13 of cutting decorative layer 12 and/or cap rock 14.The basis of planting effect therewith is what is irrelevant, is noted that during such as the Zimbabwe Door frame, above-mentioned effect bothers especially when using very dark decorative cover, because after connecting such floor, between the floor that connects, keeps tangible light lines.

According to first and second aspects of the present invention, the method that above-mentioned effect is remedied is, on top edge 33 places carry out paintedly, preferably use a kind of colorant, and its tone is corresponding to the overall tone of decorative cover 8.According to first kind of possibility, by in any manner, at the height place of the transverse edge of laminate layers 9 color layers 34 is set at least; Make this point become possibility; This illustrates in Figure 12, and top edge 33 is moved along felt tip pen 35, thereby makes transverse edge be colored as for example black.Figure 13 illustrates a kind of remodeling, and wherein the material part on top is eliminated at the height place of edge 33, for example, is used to form chamfering 35, and therefore forms the surface that is provided with color layers 34.For example be black or brown color layers 34, can be coated onto on the surface by any way, and, form that this covering layer is by colorant by for example covering layer as shown in above, such as formation such as paint, China inks, or by trans-printing or similar approach.Figure 14 illustrates a kind of remodeling, and wherein rectangular edges groove 36 is arranged between the floor 1 of connection, and side, border 37-38-39 is subsequently by painted.

Floor 1 can have the matrix 11 that also is colored as dark color, and randomly the downside on floor also is a low key tone.What therefore, provide visually feels that the floor is abundant wood based panel.

Be noted that painted cap rock 14 may reside in above the decorative cover 8, if dark-coloured decorative cover 8 then also is colored as dead color.

Should also be noted that first aspect of the present invention to grain pattern, or it is especially favourable to have an imitation of significant so-called pattern structure timber.This is a kind of like this structure, and extend with big continuous strip-like ring or annular section shown in Fig. 1 and 5 to 10 on the whole in its corresponding zone.

Should be noted that; By " imitation " of grain pattern, should understand a kind of any type of expression of grain pattern, whether irrelevant with the pattern of imitation by the reproduction technology acquisition; Therefore; A kind of is that image by real logs begins, or it produces by imagination and/or designing technique, need not begun by real logs.

Under the situation of the laminate of suppressing, floor 1 great majority are formed by big pressboard layer by layer, and wherein decorative layer 12 is wide paper web or paper form with possible cap rock 14, and great majority have the width of 2.5m, are compressed on the matrix.Subsequently, the plate of acquisition is become floor 1 by sawing.Under the situation on rectangle floor 1, for example in Fig. 1 shown in, great majority are from the pressboard sawing on the longitudinal direction of paper web.According to special aspects of the present invention, preferably using specific process structure floor in such cases, wherein clear and definite important pattern is only to be made up of the center of paper web basically, and only constitutes the floor that has time important pattern basically by the fringe area.In fact, paper web is more accurate in great majority location, center, and possible tensioning does not have any influence.Yet, district on the edge of, this tensioning will more clearly manifest the pattern of self and the decorative cover that can squint significantly.The result who has like this is, when the neutralizing layer pressing plate, between color pattern and various luster degree pattern, will have little in the center or do not have mutual skew, yet can be created in the fringe area.By now only having most important pattern in the center of pattern, the result of acquisition is that said shortcoming can be reduced.

Further specify hereinafter referring to Figure 10.As by the figure finding, such floor 1 can have the regional A of big pattern, such as having big " decorative pattern ", and the area B of more careful texture pattern.Now, this zone A is proved to be more important than area B.Obviously, the deviation ratio between color pattern and various luster degree pattern is more obvious in area B in regional A.Consider that in fact great majority are on a paper web, to express several to have the floor of different pattern, wherein some floor has pattern A and pattern B, and other floor shows do not have pattern A or almost do not have pattern A; Now, according to the present invention, preferably; The floor of A type pattern of being arranged to have said form is only in the center of paper web; And only keep the pattern of time important kind on the edge of in the district, therefore, only have or almost only have the floor of more careful pattern B.

In floor according to first aspect of the present invention, also can imitate so-called silver grain, it is actually the hardwood part of gloss, and great majority are little point-like or irregular mobile ribbon.The instance of the silver grain 40 of schematically illustrated imitation in Fig. 5 and 9.

In above-described laminate flooring 1, these silver grains can use in the following technical characterictic one or multinomially imitate with practical ways:

-by using a zone, wherein carry out a kind of change of color, for example, in the zone 41 of Fig. 6, there is a kind of color change, this color change:

-or can be that as shown in the figure, this zone 41 is by constituting with zone 28 identical colors, as its result, this color also extends to and gets into corresponding zone 29 and therefore produce color change herein;

-or can be that this zone 41 is by constituting with zone 29 identical colors, as its result, this color also extends to and gets into corresponding zone 28, and therefore produces color change herein;

-or can be that this zone 41 is by constituting with the color various colors in zone 28 and with the color various colors in zone 29;

-by using a zone, wherein, preferably increase with respect to the change of peripheral region glossiness, can see; For example, as shown in Fig. 7, use zone 42 to extend to and get into matt zone 22; Yet, also be by constituting with zone 23 identical glossiness, perhaps for example being; According to a remodeling, use a zone, wherein glossiness even be higher than the glossiness of zone in 23;

-by using a zone, for example, like the zone 43 shown in Fig. 8, wherein the overall pattern of relief 31 is local interruption;

-by the combination of using two or more possibilities that leading portion sums up.

Fig. 5 illustrates the imitation of the silver grain 40 that obtains by the combination in zone 41 and 42.

Fig. 9 illustrates the imitation of the silver grain 40 that obtains by the combination in zone 41,42 and 43.

Be noted that this technology that is used to imitate silver grain also can be used in any laminate flooring of imitation timber, no matter whether this floor has above-described various luster degree zone of extending according to grain pattern.As its result, the present invention also relates to the floor according to aspect independently, more specifically; Have a mind to be used to form the floor of floating floor overlay; Wherein this floor comprises decorative cover and based on the top layer of synthetic materials, and the imitative a kind of grain pattern of cosmetic side face mould on floor wherein, it is characterized in that; This floor side above that has the imitation of one or more silver grains, and this imitation is by one in the following technical characterictic or multinomial realization:

-by using a zone (42), this zone has the glossiness that changes with respect to its peripheral region, is preferably the glossiness of increase;

-by using a zone (43), the overall pattern that wherein imitates the relief (31) of timber pore is a local interruption.

In addition, according to this independent aspect, the imitation of this silver grain can also strengthen, at this moment by with the combination of said two possibilities in, or with the combination of one of these possibilities in, also color change is set in this silver grain position.

Figure 15 illustrates two floors 1 that have second aspect characteristic of the present invention.Corresponding floor 1 is depicted as coupled situation.For this purpose, these floors at least two relative sides or edge 2-3 place be provided with coupling part 6-7.This floor comprises decorative cover 8 and based on the top layer or the laminate layers 9 of synthetic materials, and in the side 2-3 place, their connect along said side 2-3; Position at above-mentioned top layer or laminate layers 9; Top edge 33 is shown, and under the coupled situation of two floors, this top edge intentionally is adjacent to each other.

The decoration side 16 imitation slabstones of two floors 1 or the stone material of another sheet kind.For this purpose, these floors 1 have step relief 44 in their upper side or decoration side 16, and these reliefs 44 are presented at the step transition 45 between continuous basically relief or the step 46.Owing on the top edge 33 on this floor 1, have such relief 44, shown in the floor 1 of connection between produce difference in height, the visuality that this causes said conspicuous light slit to increase.In order to cover these slits, according to second aspect of the present invention, the said top edge that deliberately is adjacent to each other 33 is painted at the height place of the transverse edge of laminate layers 9 at least, as its result, obtains color layers 34.This point is clear visible in Figure 16, and this corresponding top edge 33 that illustrates the floor 1 of Figure 15 is in the state that floor 1 skew is left.

In the instance of Figure 16, on the height at said edge 33, top layer or laminate layers 9 are to cut with respect to the plane perpendicular on floor 1.

Figure 17 illustrates the method that is used for making according to the third aspect of the invention floor 1.Especially relate to the method that is used to make floor 1; This floor comprises decorative layer 8; And based on the top layer or the decorative layer 9 of synthetic materials; Wherein these floors 1 at least two relative sides or edge 2-3 place be provided with coupling part 6-7, their allow two such floors 1 to be fitted to each other at 2-3 place, these edges.As shown in scheming, floor 1 is at one or more top edges 33 places, is provided with paintedly at least in the position of top layer or laminate layers 9, and this painted hardening material 47 being sprayed on the top edge 33 by ink-jet printer feed system 48 is realized.

Preferably, unshowned relative top edge cuts in a similar manner, and unshowned relative this painted of top edge 33 is side by side to carry out with described identical mode below the usefulness.

Be noted that when carrying out this when painted as shown in the figure, floor 1 is oriented to and makes its upper surface or decorate side 16 down.When making this floor 1, more specifically, when forming its coupling part 6-7, this orientation on floor 1 is preferential the use, and for example, this point can be known from patent WO 97/47834.Owing to paintedly preferably as one man carry out, when its top edge 33 is painted, also preferably keep this orientation on floor 1 with the formation of coupling part 6-7.

In addition, should also be noted that floor shown in Figure 17 1 after the method for carrying out the third aspect, demonstrates the characteristic of second aspect present invention.Arrangement by Figure 17 can be clear and definite, and the corresponding method that is used to form dyed layer 34 can be used in any floor 1 with laminate layers 9, and whether to be provided with relief and/or tarnish-gloss zone irrelevant with this laminate layers 9.

When carrying out when painted, to use and spray 49, its direction makes the upper surface on floor or decorates dangerous minimum that side 16 stain preferably like this.For this purpose, the head 50 of the ink-jet printer 48 in the instance of Figure 17 is arranged as the angle C of restriction, for example, is 1 ° to 5 ° with respect to the upper side on floor 1 or the angle of decoration side 16.Therefore, the direction of injection 49 is such, and decoration side 16 is positioned at outside the scope of injection 49, decorates the dangerous minimum on the side 16 thereby material 47 is dropped on.Protection screen 51 prevents that the guide 52 that stop above that on floor 1 from being stain.
