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 11. Also, a support plate for a panel and a manufacturing method for a such support plate subject of the invention.
Such a panel or such a carrier plate is in particular for a floor panel suitable.
a carrier plate in the laminate floor area are regularly HDF or MDF boards used, which have an imprint on the surface, so that a Structure that follows the decor can be achieved on the top.
the embossing process is executed parallel to a short-cycle coating, while several Paper layers together and with a mat of wood material, preferably fibers, be pressed.
the structure is thereby generated by press plates, the one Have negative structure. This process is expensive and characterized by a high wear on press plates.
the object of the invention is a panel or a carrier plate of binders and to provide fillers and processes for their preparation, with which a faster and less expensive production of surface-structured panels done can.
the different density at the top of the carrier plate in relation to the Bottom facilitates embossing or structuring of the carrier plate due to lower strength, reducing the wear of embossing sheets or other structural tools is reduced. Likewise, the structuring or embossing faster, resulting in a faster and more cost-effective production leads.
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 Urea resins
MUF resins melanin-reinforced urea resins
isocyanates can be used as glueing of the fiber in the carrier plate be used, with isocyanates with gluing factors of less than 20% are envisaged. Isocyanates offer due to their high heat resistance also the possibility to realize higher gluing factors. Also will be through the addition of isocyanates strength during a heat-intensive coating maintained the carrier plate, since with the exclusive use of Urea resins have a tendency that the backing plate during the coating suffers a loss of strength.
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 by the reduced proportion of wood material in the Plates the tendency for swelling of the support plate is reduced.
the inventive Support plate and a floor panel made with it is suitable due the lower tendency to swell (less than 5%), especially for use in Wet rooms.
the method for producing a panel, in particular floor panel, at a support plate by compacting and heating glued wooden materials provides that the carrier plate on a top with a textured Surface provided and a finishing layer on the with the embossing provided carrier plate is applied.
a different Dense at the top and bottom of the backing plate becomes the embossing the support plate facilitates, because the strength of the cover layer of the support plate on the top is lower than at the bottom.
the overall strength of the panel is only slightly affected, since the bottom is very high density and Has strength and due to the high Beleimungsanteile improved material values can be achieved.
the unilateral lowering of the bulk density of the support plate on the top during the production process is carried out either by grinding a topcoat of Top or by one-sided application of good heat conductors, such as water, on the bottom before heating and compacting the wood material at the Production of the carrier plate.
the feeding of the heat-conducting media for example by spraying the wood materials, e.g. designed as a fiber mat are, leads to a faster penetration of heat into the fiber mat.
the adhesives This activates faster and results in increased compaction on one side of the fiber mat. On the opposite side is the compression correspondingly lower, so this page for easier surface embossing can be used.
the fiber structure remains at the same time Differences in density at the top and bottom get what has an advantageous effect on the strength of the support plate and the panel.
the structure of the support plate by Sanding be generated.
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 End layers 10 are on the outer end of the support plate 1 forming Cover layers 7, 17 applied, 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 enlarge 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 also shows the structured surface of the upper side 1 5 and of it applied final layer 10, wherein the structure by embossing during coating can be done with the final layer 10.
the reduced density of Cover layer 17 on the top 15 in relation to the bottom 5 easier the embossing process and reduces the wear of embossing plates.
thermally conductive ones may be used Media specifically introduced into the fibers or applied to the fibers to give an asymmetric density distribution across the thickness of the backing plate achieve.
water other liquids can be used.
the mat to be pressed is adjusted so that the support plate is an asymmetric Has density distribution, for example by the upper cover layer on a material that can not be so highly compressed.
