The invention relates to Plato or blankaartia structural element, in particular for use as a structural element of furniture or a wall, ceiling or floor panel containing the basis of the wood material, printed on the basis of the decor, following the decor transparent gloss varnish coat and followed with a three-dimensional structure of the covering lacquer layer.
Wood boards with a decorative coating are often used as flooring panels, for walls and ceilings or as structural elements of furniture. Such panels are mostly rectangular in shape and, at least at its longitudinal edges are usually equipped with profiles that connect adjacent panels to education covering a large area. For this purpose, widely distributed wood-fiber Board manufactured by the method of drying, the so-called MDF boards (Medium Density Fiberboard - fibreboard medium density) or HDF boards (High Density Fiberboard - fibreboard, high density).
To provide wood boards need decor, impregnated in a known manner by an artificial resin and pre-dried decorative paper at high temperature and under high pressure is pressed directly on the surface plate. Because the ku these impregnate when pressing strive to shrinkage, they create tension, so made this way slabs, also called laminates, it is necessary to provide impregnated paper always on both sides to prevent due to the voltage bending of plates.
In addition to laminated fiberboard panels these kind of plates are also used with the direct printing. Such panels are known for example from EP 1645339 A1. When this fibrous plates are supplied with liquid covering means, and painted clay layer is printed decor such as wood decor, and then apply one or more transparent sealing layer. In EP 1645339 A1 describes the production of a textured surface by applying a first coating and a second transparent coating with spatial varying the applied amount.
In EP 1482085 A1 describes envisaged, in particular as a flooring surface facing containing base, decor, in particular wood decor, matte primer (primer and top coat gloss. The soil covers only part of the substrate and deposited by the method of direct printing. Top coat gloss covers, on the contrary, the soil and, in addition, basically, the entire upper side of the base, and in the finished surface of the lining covering the matte primer part p is Krasnogo layer has a lower degree of gloss what it does not cover the frosted ground part.
Gloss is an optical property of the reflective surfaces. In the physical sense, the gloss is defined as the ratio between the directed and reflected absently shares falling on the surface of the quantity of light. Quantitatively Shine can be determined using blastomeres; details are given in DIN 67530 DIN EN ISO 2813. For directly coated plates defining gloss set in EN 14323 (current edition from 01.06.2004). In accordance with this gloss is determined using the so-called reflectometer according to DIN EN ISO 2813. The principle of the reflectometer based on the measurement of directional reflection. This is measured reflected light intensity in a narrow range of angles of reflection. The measurement results are not to the quantity of incident light, and the black polerowanie glass sample with a specific refractive index (1,567). For this sample, the measured value is set to 100 units of gloss (GU - gloss units or point gloss). There are materials, the surfaces of which have a higher refractive index than that used for calibration black glass sample. Therefore, certain surfaces of materials having values of gloss over 100 GU, such as polished metals. For Otsego differentiation of the measured measurement values depending on Shine are held at different angles. According to DIN EN ISO 2813 in the case of surfaces with mirror luster (≥70 GU) in addition to the usual measurements at an angle of 60° are also measuring angle of 20°.
The basis of the invention lies in the task of creating a structural element or panel described above kind having/having an unusual appearance of used or vintage item, natural/natural to the touch and does not require/require large production costs.
This problem can be solved through constructive element with signs of paragraph 1 of the claims.
Prepositional structural element has a base made from wood material, mainly wood-fiber plates, and includes a printed based on the decor, following the decor transparent gloss varnish coat and followed with a three-dimensional structure of the covering lacquer layer. Covering lacquer layer forms a surface structure with greatly varying degree of gloss and the surface of the structural element, at least one running parallel to it is the difference in gloss of at least 25 GU with respect to the linear distance from the surface 20 mm
Prepositional structural element differs, thus, large differences in gloss, and the areas of the upper surface and are relatively opaque, while lying deeper because of the three-dimensional structure portions are shiny or have a mirror Shine. The matte appearance of the lacquer surface of the structural element corresponds, thus, the appearance of old, with traces of use or old painted surfaces. Structural element is due to this unusual and interesting appearance. Due to its matte or how ever used the appearance of structural element creates at the same time relative to the natural effect compared to, for example, with the panel having a generally mirror Shine finish. Moreover, the natural effect is optimized by a three-dimensional structure of the covering lacquer layer, namely, in particular, in relation to the touch. Optical and tactile effects of the structural element is achieved by a small number of process stages, which requires, in General, relatively small production costs. In this regard, it is noteworthy, in particular, that the three-dimensional structure is created directly when applying the covering lacquer layer by means of an engraved print of the shaft, preferably by way of indirect gravure printing. Subsequent mechanical embossing lacquer coating layer or so-called "chemical etching" due to consistent grease the two liquid, vzaimoottalkivayuschiesya of coating materials in the manufacture of the proposed structural element or panel is not provided. Transparent shiny followed textured, relatively matte lacquer layers structural element, in contrast, are applied mainly by continuously operating the printing cylinders by way of gravure printing and coating varnish and three-dimensional structure is applied or created in a single operation.
One preferred structural element is characterized by the fact that in comparison with brilliant transparent lacquer layer covering lacquer layer has at least 45 GU, mostly, at least 50 GU lesser degree of gloss at an angle of measure 60° according to DIN EN ISO 2813. Structural element has in this embodiment a particularly large differences in gloss, which further enhances the effect of old or look old surface.
According to another preferred variant, the surface of the structural element, at least one running parallel to it is the difference in gloss of at least 30 GU, mostly, at least 35 GU with respect to the linear distance from the surface 20 mm this option Also increases the effect of old or look old surface.
In particular, if the structural element should be used as a floor panel, it is preferable if, according to other variant between decor and brilliant transparent lacquer layer is transparent lacquer layer containing increasing the wear resistance of the particles. Due to this, the decor is protected from abrasion.
The impression of a natural or used structural element is especially great if the surface structure according to another preferred variant has an average maximum height of roughness profile in the range from 10 to 400 μm, predominantly in the range of 50 to 400 microns.
Another preferred variant of the constructive element is that its surface structure is made corresponding to the decor. So, for example, provides that in the case of simulated wood decor three-dimensional structure corresponds to his image texture, and, for example, in the case of the printed decor in the form of tile three-dimensional structure corresponds to the simulated tiled the floor. Similarly, the decor of the structural element can be a decoration in the form of natural stone such as slate or granite, and three dimensional structure of the covering lacquer layer is then simulates the surface of the stone is treated with flame and/or brush
Other preferred variants of the structural element are listed in the dependent claims.
Below the invention is explained in more detail with examples of its implementation, shown in the drawing, which are:
- figure 1: schematically a device for direct printing on slab-on-grade structural elements of wood material;
- figure 2: schematic perspective view of two interconnected panels;
- figure 3: enlarged detailed side view of the connection zone panels of figure 2;
- figure 4: a schematic cross-section of a fragment of a structural element or panel;
- figure 5: a schematic cross-section of a fragment of another structural element or panel.
1 schematically shows a device for direct printing on wood plates 1. Belt 2 there are several plates 1, separately and in turn supplied to various sections 3-7 processing. The conveying direction indicated in figure 1 by the arrow and passes from left to right. Instead of several separate plates 1 in the device can handle one large or one infinitely manufactured wood stove, after which the following processing is cut into individual plates.
In sections 3, 4 on each wood plate 1 by way of gravure printed multicolor decor, for example on ewenny or in the form of natural stone. For this section include shafts for applying (print rollers) 3.1, 4.1, includes at least one grooved shaft.
Next, the surface of the plates 1 after printing the decor in section 5 is covered with a transparent sealing layer. In section 5 is applied, mainly over the entire area of the surface layer (sealing layer) made of lacquer. For this section 5 includes a shaft 5.1 for the application, which causes the surface of the plates 1 uniform, mostly smooth lacquer layer. Transparent lacquer contains increase the wear resistance or abrasion resistance of the particles, such as corundum/or quartz particles. By the next processing device 5.2 coated at least partially dried or cured. Processing device 5.2 can provide drying and curing, for example, by a flow of warm air or electromagnetic radiation, in particular UV radiation.
For section 5 followed by section 6, which by means of shaft 6.1 pre-applied sealing or corundum lacquer layer is applied to a transparent gloss varnish layer. It represents mainly the ground with a mirror Shine with a gloss in the range from 70 to 85, for example about 80 GU.
This is followed by section 7, which by means of an engraved printing cylinder (print roller) 7.1 on the brilliant or with gloss lacquer layer (soil) method indirect gravure printing is applied a matte top coat varnish. Printing cylinder 7.1 is very planar, i.e. pre-printed brilliant or with gloss varnish coat (primer) on the whole area or, basically, the entire area is covered with matte opaque finish. Covering lacquer layer creates in dry condition in combination with or possessing a brilliant mirror Shine lacquer layer three-dimensional surface structure with greatly varying degrees of sheen. The applied amount of coating of varnish varies with the square by a factor of 15-20.
Top coat varnish is applied by a printing cylinder 7.1 so that the printing cylinder 7.1 in its engraved recesses and protruding relative to the areas of its lateral surface wetted by a fluid opaque finish. This top coat varnish is selected so that the covering lacquer layer in the finished state of the structural element is on a separate parcels less, at least 40, preferably at least 45, particularly preferably at least 50 GU degree of gloss at an angle of measurement of 60° according to DIN EN ISO 2813 than pre-printed transparent gloss varnish layer. In dry condition lacquer coating may be transparent or partially opaque, and in the latter case, the opaque areas to form elevated userdirectory surface structure.
In the next processing device 7.2 marked the final coating, i.e. textured top coat varnish, at least partially solidifies, so that the three-dimensional structure sufficiently hardened, fixed and does not spread as a result of spreading. At this stage, the curing is situated (located) below, applied (deposited) in the preceding sections 6, 5, 4 and/or 3 coatings (coatings) may not yet be completed.
Of course, in addition to the above mentioned sections 3-7 can be provided by another section of the processing. So, for example, on the opposite (bottom) side of the carrier plate 1, if necessary, may be applied to the reverse surface. Application of a reverse coating, predominantly of color, is carried out, for example, by means of shafts. To reverse drying coatings are used, for example, dryers hot air or hot radiators.
After the decorative coating, improving the resistance to abrasion of the sealing layer, transparent gloss primer, textured top coat varnish (final layer) and, if necessary, reverse coating will be sufficiently solidified, covered thus bearing plate large format through saws, etc. is cut into a large number of panels 1.1, 1.2. Then in the longitudinal and, if necessary, also in the transverse butt the sides of each panel is milled the I profiles to connect with a positive locking of the panel with the panel. The profiles made in the form of a groove 1.3 and crest 1.4 (figure 3).
Figure 2 shows two interconnected panels 1.1, 1.2. They are made in the form of flooring panels. Similarly, they can be used for walls or ceilings.
Figure 4 schematically shows a section of the fragment of the structural element or panel 1.1. Plate-like structural element or panel 1.1 contains the base 10 of wood material, mainly wood-fiber plate medium or high density. On the base 10 by means containing engraved printing cylinders 3.1, 4.1 of the printing apparatus 3, 4, or digital printing device printed decor 11, mainly wood, tile or natural stone. Therefore, the decoration is printed on the base 10 by way of direct printing.
For the decor layer 11 is transparent protective or sealing layer 12 containing corundum and/or other, which increases the wear resistance of the particles.
Transparent protective or sealing layer 12 is covered with a transparent glossy varnish layer (ground) 13. The lacquer layer 13 is formed with a varnish, which in the cured state has a degree of gloss of at least 70, mostly, at least 75, and particularly preferably about 80 GU at an angle measurement 20° according to DIN EN ISO 2813. Shiny or with gloss lacquer layer 13 pokr is characteristic decorative side of the structural element or panel 1.1, basically, over the entire area.
The lacquer layer 13 is covered, finally, covering lacquer layer 14. Top coat varnish printed on shiny lacquer layer 13 by way of indirect intaglio engraved by shaft 7.1, resulting in a cured coating lacquer layer 14 has a three-dimensional structure with cavities (pores) 14.1. The average maximum height of the irregularities of the surface structure is in the range from 10 to 400 μm, predominantly in the range of 50 to 400 μm. This surface structure is made corresponding to the decor, such as simulated wood grain.
Covering lacquer layer 14 deposited on a transparent shiny lacquer layer 13 mainly throughout the area and formed a very matte finish, which in the cured state has a degree of gloss of less than 20, mostly less than 15 and particularly preferably only about 10 GU at an angle measuring 60° according to DIN EN ISO 2813. In combination with a brilliant basis (lacquer layer 13) occurs, thus, the surface structure with greatly varying degrees of sheen.
If you look on the surface and width of the structural element 1.1, at least one running parallel to it the direction it is possible to ascertain the difference in gloss of at least 25 GU, for example, about 30 or even 35 GU, relative to the linear distance from the surface 20 mm When RA is watching at a greater linear distance to the surface can be stated in a constructive element 1.1 gloss variation between 50 and 60 GU.
Formed covering lacquer layer structure includes cavities (pores) 14.1 and sublime about them sections 14.2 surface. The upper or elevated portions 14.2 are less, at least 35 GU, mostly, at least 40 GU degree of gloss at an angle of measure 60° according to DIN EN IS 0 2813 than deepening 14.1.
With the greatest degree of gloss of the surface of structural element 1.1, 1.2; 1.1' correspond to the recesses 14.1. i.e. they are formed covering lacquer layer recesses 14.1.
The proportion of the surface of the covering lacquer layer 14 having a degree of gloss of less than 25 GU, in particular less than 20 GU, when the angle measuring 60° according to DIN EN ISO 2813, is at least 50%, mostly, at least 60% of the front structural element 1.1. In the framework of the invention is, in particular, one option, in which the proportion of the surface of the covering lacquer layer 14 having a degree of gloss of less than 25 GU, in particular less than 20 GU, when the angle measuring 60° according to DIN EN ISO 2813, is at least 65%, mostly, at least 70% of the front structural element 1.1.
Pictured (pictured) figure 5 structural element (panel) 1.1' differs from the example shown in figure 4, only the fact that the lacquer coating 14 deposited on a transparent shiny lacquer layer 13 is not on the whole square is, and in the area of the recesses (ERP) 14.1 three-dimensional structure leaves it partially open.
Implementation of the invention is not limited to the above examples. On the contrary, there are many options that uses described in the attached formula of the invention, even in case of modifications. Thus, the invention can be preferably implemented, in particular, also in the case of structural elements of the wood material in the form of profiles, for example in the case of plinths with direct printing.
