Definitions

  • the present invention relates to a coated wood-based panel, in particular for the production of a floor, ceiling or wall covering according to the preamble of the independent device claim 1 (see example DE 10 2004 031 547 A1 ), as well as a method for coating a wood-based panel, according to the preamble of the independent / claim claim 9 (see, eg WO 2007/042258 A1 ).
  • laminate panels for floor or ceiling coverings are known from the prior art.
  • laminate panels are relatively inexpensive.
  • Laminate panels are usually made of a 4 to 12 mm thick support plate made of MDF or HDF material, so a relatively cheap wood material, on top of a with a decor printed paper is glued on.
  • On the underside of the support plate is usually a so-called Gegenzugpapier which is intended to counteract a delay of the support plate by the applied decorative layer.
  • it is usually applied to a so-called overlay paper, which is impregnated with a resin such as an amino resin and are applied to the very fine abrasion resistant particles, such as Alumuniumoxidp
  • overlay paper which is impregnated with a resin such as an amino resin and are applied to the very fine abrasion resistant particles, such as Alumuniumoxidp
  • the various layers of the laminate panels are joined together and the resins used are cured. It thus creates a durable, abrasion-resistant decorative surface.
  • a method for coating a wood-based panel in which in a single coating step, a relatively thick protective layer of plastic material is applied to the surface of a panel.
  • the plastic material used is a polymerizable acrylate system which can cure via polymerization. The polymerization is initiated by irradiation, so that a complete conversion takes place through the thickness of the applied layer.
  • the object is a coated wood-based panel, as well as to provide a method for coating a plate, which has particularly advantageous mechanical properties.
  • abrasion values of the highest abrasion class AC 5 in accordance with prEN 15468 are achieved.
  • the surface is characterized by high micro-scratch resistance (Mar-Resistance) and impact resistance according to Class 33 (prEN 15468).
  • the characteristic values for resistance to chemicals and water vapor, chair castors and furniture footprints certainly correspond to prEN 15468.
  • the method allows a surface in which, in addition to printing, a deeply embossed decorative structure, for example a brushed wood structure or a stone structure can be introduced. The invention is thus particularly well suited for the provision of floor panels.
  • the coated wood-based panel is in particular a floor, ceiling or wall panel, or a wood-based panel intended for further processing to a floor, ceiling or wall panel, and comprises a front and a back, wherein at least the surface of the front with a polymer coating is provided.
  • the term wood-based panel is to be understood broadly and comprises, for example, both boards made of real wood and boards made of MDF, HDF, chipboard, composite panels, OSB boards and the like.
  • the wood-based panel may be further provided with additional coatings, papers, veneers or the like on its front and / or back surfaces.
  • the polymer coating has a hardness gradient after curing, so that the hardness of the polymer layer decreases with increasing depth seen from the surface. That is, the polymer layer preferably has the greatest hardness on its outer surface and the lowest hardness near the interface between the coating and the surface of the wood-based panel, with a falling course between the two extremes.
  • the present invention also relates to the example, by the technical features or method steps of claim 9 defined method for coating a wood-based panel, in particular a floor, ceiling or wall panel, or a wood-based panel is further processed to floor panels, wherein a wood-based panel in a first liquid coating agent is applied to a first step and a second liquid coating agent is applied to the still moist first coating agent, wherein the liquid layers interpenetrate each other according to the physics of liquids.
  • the respective concentration curve corresponds to a straight line. Since with higher viscosity liquids with short mixing times disturbances can occur ideally, one must assume that the actual concentration curves correspond only approximately straight lines and deviations are possible.
  • the fluids For example, polymerizable acrylate systems that differ in the double bond content, it follows from the above, that analogous to the concentration gradient of the two liquids to each other, a difference in the number of double bonds from one side to the other side of the layer. If polymerization is initiated in such a layer, for example by UV excitation, and it is assumed that almost complete conversion of the double bonds takes place under inert conditions, a polymer layer with a gradient of the crosslinking sites is formed.
  • the hardness in such a system gives information on the crosslink density. If, for example, the microhardness (Martens hardness DIN EN ISO 14577) is measured within a layer produced correspondingly from two polymerizable liquids, a hardness gradient results analogously to the crosslinking density. For example, the layer can be removed stepwise using a Taber Abraser test according to EN 13329. The curve of the hardness gradient corresponds in completely the same way to the concentration gradient of both liquids described above. Ideally, the mixing of the liquids occur straights.
  • a first layer of 45 g / m 2 is rolled on an HDF support plate, wherein the coating composition of the first layer, for example, to 35% of a 1, 6-hexanediol diacrylate and 65% of a polyester acrylate.
  • a second layer having a mass of 40 g / m 2 is applied to this layer, wherein the coating agent the second layer consists for example of a mixture of 70% polyurethane acrylic acid ester and 30% dipropylene glycol diacrylate.
  • Both layers in the present case contain a photoinitiator.
  • the total liquid layer thus produced is exposed to UV radiation under a nitrogen atmosphere and the entire layer is polymerized.
  • the double bond conversion is about 98%.
  • the layers may additionally be provided with abrasion resistant particles, e.g. with fine corundum particles. These may be present in a dispersion, for example, before the coating process in one of the two or even in both coating compositions or they may be sprinkled in a separate process step on the still moist, but already applied coating compositions.
  • the concentration of 1,6-hexanediol diacrylate may be between 10 and 60%, more preferably between 20 and 40%; the concentration of polyester acrylate between 40 and 90%, more preferably between 50 and 80% lie; the concentration of polyurethane acrylic ester is between 45 and 95%, more preferably between 55 and 75%, and the concentration of dipropylene glycol diacrylate is between 5 and 55%, more preferably between 15 and 35%.
  • the substances mentioned are intended to illustrate the principle of a layer with hardness gradients on the basis of a preferred embodiment. Of course, a variety of other or other polymerizable substances can be used instead. Polymerizable acrylates are particularly preferred substances for the coatings described herein.
  • the coating agent of the first, as well as both the second and possibly further layers may consist of a single polymerisable substance or of mixtures of substances.
  • Particularly suitable substances are polymerizable acrylates in general and here in particular the substances: 1,6-hexanediol diacrylate, polyester acrylate, polyurethane acrylic acid ester and dipropylene glycol diacrylate.
  • Particularly suitable for the first layer is a mixture of 1,6-hexanediol diacrylate and polyester acrylate.
  • a mixture of polyurethane acrylic acid ester and dipropylene glycol diacrylate is particularly suitable.
  • other additives may be present, such as flow aids, wetting aids, dyes, abrasion resistant particles, etc. It is essential that these other components allow the above-described crosslinking or penetration and polymerization is still possible.
  • the specified substances are preferred, but the person skilled in the art recognizes that it is not explicitly the use of the specified substances, but essentially the provision of polymerizable coating compositions.
  • a coating system for coating wood-based panels 10 is shown.
  • the wood-based panels 10, such as solid wood panels, HDF, MDF or chipboard, are passed through a roller conveyor 12 through the various stations of the coating plant.
  • a first liquid coating agent is produced by means of a rotating application roller 15 20 applied in a continuous coating on the wood-based panels 10.
  • the application roller 15 is supplied via a supply device 16 with coating agent.
  • a second liquid coating agent 21 is applied to the still moist first coating agent 20 via a further rotating application roller 18.
  • the applicator roll 18 is supplied by means of a feed device 19 with the second liquid coating agent.
  • the job can of course be done with any other suitable application method, such as a sprayer or a doctor blade or the like. It is only important that the application of the second layer takes place, as long as the first layer is still wet enough, so that there is a partial mixing of the layers.
  • the coated plates 10 After leaving the coating station 17, the coated plates 10 are transported to a curing station 30, where the layers are cured by means of UV lamps 31. On their way from the coating station 17 to the curing station 30, there is a partial mixing of the liquid coating agent 20 and 21, which occurs in particular at the interfaces of the two coating agents. The mixing is naturally greater, the closer you are to this interface of the two layers. The hardening of the layers in the curing station 30 stops the mixing process and sets the once set mixing ratio and thus the mechanical properties of the coating produced.
  • the extent of mixing at the interfaces - which takes place by itself and preferably without external mechanical action - depends on the time that elapses between the application of the second coating agent 21 to the still moist first coating agent 20 and the curing in the curing station 30 ,
  • the mixing the two coating agents are also influenced by the respective viscosity of the coating agent, the rule of thumb being that the higher the viscosity, the lower the mixing per unit time.
  • Fig. 2A shows the state of the two applied to a wood-based panel 10 coating agent 20 and 21 immediately after application of the second coating agent 21. At this time, virtually no mixing has taken place.
  • the coating agents 20 and 21 in the present case are polymers which each have different numbers of CC carbon double bonds.
  • the first coating agent 20 has a lower number of CC double bonds than the second coating agent 21. Due to the larger number of CC double bonds in the coating agent 21, this will have a greater hardness after curing than the coating agent 20, which with less CC double bonds is provided.
  • the two coating agents 20 and 21 are applied wet-on-wet, starting from the interface 22 between the two layers, they are mixed together, as shown in FIG Fig. 2B is indicated. This means that more double bonds are present in the region close to the border to the boundary layer 22 as a result of the mixing process in the underlying layer and, accordingly, in the area close to the border of the overlying layer, somewhat fewer double bonds than before mixing.
  • Fig. 2C shows the two layers, after the mixing has advanced a little further and has reached a suitable degree of mixing. If at this time the curing of the coating agent, for example by means of UV radiation, takes place, this degree of mixing is determined, since naturally no mixing can take place in the hardened layers.
  • the hardness profile of a coating according to the invention (example with hardness gradient) and a coating according to the prior art is applied.
  • the inventive example consisted of a ground and provided with a primer wood-based panel, were applied to the two different coating wet-on-wet.
  • the first applied coating agent consisted of about 35% 1, 6-hexanediol diacrylate and about 65% polyester acrylate and was applied at 45 g / m 2 .
  • the second coating agent which was applied to the still moist first layer, consisted of about 70% polyurethane acrylic acid ester and about 30% dipropylene glycol diacrylate and was applied at 40 g / m 2 . After the second layer was applied, it was waited 10 seconds to allow the viscous liquid materials to mix. Subsequently, the two layers were completely cured together.
  • the prior art example consisted of a conventional coating wherein several thin layers of material were applied one at a time, and between the respective application processes, the previously applied layer was cured.
  • the lower 3 layers consisted of a mixture of 70% polyester acrylate and 30% 1, 6-hexanediol diacrylate with an application thickness of 12 g / m 2 .
  • the two upper layers consisted of 70% polyurethane glycol diacrylate and 30% dipropylene acrylic acid ester and the two upper layers contained 15% corundum with a mean particle size of D 50 of 25 microns.
  • the test was carried out according to the European standard for laminate flooring DIN EN 13329 with a Taber Abraser tester 5151 from Taber Industries. After every 200 revolutions with S-41 abrasive paper, the hardness and trace depth of the samples were determined. The determination of Martens hardness (registering hardness test under test force effect) was carried out according to DIN EN ISO 14577.
  • the tester used was a "Fischerscope H100" made by Helmut Fischer GmbH. The following test parameters were used: maximum force: 50/30 mN and measuring time: 20 seconds.
  • the determination of Spurt depth was performed with a mechanical palette measuring device. As a tester, a Perthometer S3P Perthen was used.
  • the column “Revolve” indicates the number of revolutions performed with the Taber Abraser tester.
  • the column “depth trace” indicates how many micrometers of material of the coating were removed from the original surface at the four measuring points 1-4.
  • the “Depth Hardness” column indicates by how many micrometers the test mandrel has entered the coating at the four measuring points 1-4.
  • the hardness in Newton per mm 2 for the four measuring points 1-4 is then given in the "Marten hardness” column. Below the individual values, the respective mean value for the four measuring points is indicated. From the table presented above, it can be clearly seen that the hardness of martensite decreases as one goes deeper into the hardened, finished layer. It can also be seen that at 800 and 1000 (total) revolutions there is a slight increase in Martens hardness. This is due to an irregular mixing of the two coating compositions used, which is difficult to completely avoid in practice.
  • the "absolute" values mean that only the pure numerical values are entered into the above formula, ie without the associated unit of measure " ⁇ m" or "N / mm 2 ".
  • the initial value of the above example with hardness gradient is 140.8 N / mm 2 (see Table 2)
  • This results, for example, in upper and lower bounds for Y (x 3.5) of 140.1 and 130.3, respectively.
  • 132.8 results for the upper limit and 20.8 for the lower limit, respectively.
  • the initial hardness value of the coating is the value in the first few microns of the coating. Due to the commonly used measuring method It is difficult to determine the hardness for the penetration depth "0 ⁇ m" by means of a test mandrel which penetrates a few ⁇ m into the coating. The term “substantially” is therefore chosen because it is difficult to achieve a perfectly uniform mixing of the materials, so that it can come in reality again and again to individual small outliers, such as the hardness value of 104.2 Newton / mm 2 at a depth of 42.1 ⁇ m (see Table 2) of the hardness gradient example discussed above. In addition, the values extremely close to the surface of the wood-based panel are generally inaccurate, since the residual layer thickness to be measured must have a certain minimum thickness in order to allow meaningful measurements.
  • the residual layer thickness should therefore be at least 5 ⁇ m, preferably 10 ⁇ m and even more preferably at least 20 ⁇ m, for meaningful measurements.
  • the last 20 ⁇ m of the layer, close to the wood-based panel, does not necessarily have to follow the preferred hardness gradient described above, although this is of course preferred.
  • the hardness gradient essentially follows the following relationship: - 2 . 5 ⁇ x + C ⁇ Y x ⁇ - 0 . 4 ⁇ x + C
  • the meaning of the above-described relationships of the hardness gradients is illustrated by the example with hardness gradient.
  • the given absolute values for hardness and depth are merely exemplary. Of course, it is also possible to apply overall layers with significantly greater thicknesses or lower thicknesses.
  • the absolute value of the hardness of course depends on the materials used and may also be greater or less than the values of the example with Hardness gradient. However, the magnitude of the given values for the hardness gradient example is particularly preferred and suitable for use in a floor panel.
  • the proposed method is particularly suitable for the coating of floor panels, or for the coating of wood-based panels which are further processed to floor panels, since here the beneficial mechanical properties of the hardness gradient most affect.
  • the presented coated wood-based panel is for the same reason preferably a floor panel, or a coated wood-based panel, which is intended for further processing to a floor panel.
