Definitions
- the invention relates to a panel according to the preamble of claim 1 and a method for producing a panel according to the preamble of claim 10. Also, a manufacturing method for a support plate is the subject of the invention.
- Such a panel is particularly suitable for a floor panel.
- HDF or MDF boards are regularly used, which have an embossing on the surface, so that a structure that follows the decor can be achieved on the top.
- the embossing process is carried out in parallel with a short cycle coating, while several layers of paper are pressed together and with a mat of wood material, preferably fibers.
- the structure is thereby produced by press plates which have a negative structure. This process is expensive and is characterized by a high wear on press plates.
- the object of the invention is to provide a panel or a carrier plate of binders and fillers and process for their preparation, with which a faster and cheaper production of surface-structured panels can be done.
- the different density at the top of the carrier plate relative to the bottom facilitates embossing or structuring of the carrier plate due to the lower strength, thereby reducing the wear of the embossing plates or other structural tools. Also, the structuring or embossing can be done faster, resulting in an overall faster and cheaper production.
- the support plate Due to the design of the support plate with a density of less than 700 kg / m 3 with simultaneous Beleimungs tint greater than 10% is achieved that the support plate has almost plastic-like properties in terms of weight and strength, but the material use due to the embedded wood materials, preferably fibers, essential is lower.
- a further embodiment provides that the carrier plate has a density between 400 kg / m 3 and 650 kg / m 3 , whereby an optimal strength in relation to the density and the use of material is effected.
- urea resins UPFs
- melanin-reinforced urea resins UDF
- isocyanates can be used as a gluing of the fiber in the support plate, wherein isocyanates with gluing factors of less than 20% are provided. Isocyanates offer due to their high heat resistance also the possibility to realize higher gluing factors. Also, by the addition of isocyanates, the strength is maintained during a heat-intensive coating of the backing plate, since the exclusive use of urea resins tends to cause the backing plate to lose strength during coating.
- the support plate has a non-uniform density distribution over the cross section from the top to the bottom, wherein the top layer located on the bottom have a density in the range of 1000 kg / m 3 , whereas the middle layers in cross section to 400 kg / m 3 - 600 kg / m 3 are compressed.
- the upper side has a lower density compared to the lower side, but advantageously a greater density than in the middle of the carrier plate.
- the higher densification on the top and bottom sides ensures that high resistance to vertical, mechanical stress is achieved, as is required, for example, when using floor panels.
- a panel with such a carrier plate is provided on the top and the bottom in each case with a finishing layer, which usually consists of a melaningetränkten decorative layer or Gegenzug harsh to additionally protect the carrier plate from mechanical damage.
- the increase of the gluing factor leads to an improved moisture resistance, as due to the reduced proportion of wood material in the Plates the tendency for swelling of the support plate is reduced.
- the penetration of moisture in the region of the connection points of two support plates or two floor panels leads to a swelling of the support plates in this area and thus to a destruction of the floor.
- the support plate according to the invention and a floor panel produced therewith are suitable, in particular for use in moist rooms, owing to the lower tendency to swell (less than 5%).
- the method for producing a panel in particular a floor panel, in which a carrier plate is produced by compacting and heating glued wooden materials, provides that the carrier plate is provided on a top side with a structured surface and a final layer is applied to the embossed carrier plate.
- the embossing of the carrier plate is facilitated because the strength of the cover layer of the carrier plate at the top is less than at the bottom.
- the overall strength of the panel is only marginally affected, as the underside has a very high density and strength and due to the high Beleimungsanteile improved material values can be achieved.
- the unilateral lowering of the density of the support plate on the top during the production process is carried out either by grinding a top layer of the top or by one-sided application of good heat conductors, such as water on the bottom before heating and compacting the wood material in the production of the support plate.
- the feeding of the heat-conducting media for example by spraying the wood materials, which are formed for example as a fiber mat, leads to a faster penetration of heat into the fiber mat.
- the adhesives are thus activated faster and there is an increased compaction on one side of the fiber mat. On the opposite side, the compaction is correspondingly lower, so that this page can be used for simpler surface embossing.
- the fiber structure is maintained with simultaneous density differences at the top and bottom, which has an advantageous effect on the strength of the support plate and the panel.
- the structure of the carrier plate can be created by abrading.
- Figure 1 shows in cross section a floor panel with a support plate 1, on the top 15 and bottom 5 each have a final layer 10 is applied.
- the final layers 10 are applied to the outer end of the support plate 1 forming cover layers 7, 17, preferably glued and protect the support plate 1, for example, against moisture and mechanical stress. Also, these end layers 10 may have a decor and increase the mechanical stability of the floor panel.
- the carrier plate 1 is made of a fiber material, which is usually used for the production of HDF boards, alternatively or additionally other wood materials are incorporated.
- the cover layers 7, 17 of the carrier plate 1 have a substantially higher density, with densities of up to 1000 kg / m 3 being achieved in the cover layers 7 of the underside 5, in the cover layer 17 of the top side 15 Lower densities are set.
- the density continuously decreases to the center M of the carrier plate 1, wherein a corresponding density distribution over the thickness d of a carrier plate 1 in the figure 2 is shown.
- the lowest value for the density ⁇ in the center M of the carrier plate is achieved, while the density ⁇ is increased over the thickness d of the carrier plate starting from the center M, in order to provide on the surfaces of the cover layers 7, 17 Achieve maximum, wherein the maximum value at the top 15 is less than the maximum value at the bottom 5.
- the support plate 1 Due to the extremely high density in the top layer 7 of the bottom 5 in the range of 1000 kg / m 3 , the support plate 1 is given the necessary resistance to vertical, mechanical stresses, in combination with the use of UF or MUF resins, optionally in Mixture with isocyanates, a special flexibility can be generated within the plate.
- the addition of isocyanates improves the moisture resistance of the carrier plate 1, so that the essential properties of the carrier plate 1 are determined by the resins used or introduced plastics.
- FIG. 1 further shows the structured surface of the upper side 15 and of the final layer 10 applied thereon, wherein the structure can be effected by embossing during the coating with the final layer 10.
- the reduced density of the cover layer 17 at the top 15 relative to the bottom 5 facilitates the embossing process and reduces the wear of embossing plates.
- heat-conducting media can be deliberately introduced into the fibers or applied to the fibers to achieve an asymmetric density distribution across the thickness of the carrier plate.
- other liquids can be used.
- the mat to be pressed is adjusted by an adapted scattering of the wood materials or fibers so that the support plate has an asymmetric density distribution, for example by the upper cover layer is made of a material that can not be so highly compressed.
