Definitions

  • the present invention relates to a wood-based panel according to the preamble of claim 1 and a method for its production according to claim 14.
  • Laminate flooring has become established in the global flooring market over the past twenty years, although there is still no saturation in many submarkets. This success and the high acceptance of laminate flooring is based above all on the good property profile and the possibility of imitation of wooden floors. Another positive aspect is that the covering is predominantly made of wood and thus has ecological advantages over many other floor coverings.
  • laminate floors also have some drawbacks that relate in part to the backing plate and partly to the surface.
  • the surface of laminate floors usually consists of a cured synthetic resin.
  • This resin is typically a melamine-formaldehyde resin from which, among other things, utensils such as crockery and cutlery are made.
  • a surface of melamine resin is particularly criticized that it feels hard and cold when walking or when touching. This phenomenon is caused by other plastics - high thermal conductivity.
  • the present invention is therefore based on the object to provide a provided with a resin layer wood material panel, in particular in the form of a laminate floor, with a user-improved feel. In doing so, previous positive product characteristics should be changed as little as possible and no significant technical or financial expenditures should be necessary.
  • a mixture of silanes of the general formula (I) can also be used.
  • the radical X is advantageously selected from a group comprising fluorine, chlorine, bromine, iodine, C 1-6 -alkoxy, in particular methoxy, ethoxy, n-propoxy and butoxy, C 6-10 -aryloxy, in particular phenoxy, C 2-7 -Acyloxy, in particular acetoxy or propionoxy, C 2-7 alkylcarbonyl, in particular acetyl, monoalkylamino or dialkylamino with C 1 to C 12 , in particular C 1 to C 6 .
  • Particularly preferred hydrolyzable groups are C 1-4 alkoxy groups, especially methoxy and ethoxy.
  • non-hydrolyzable organic radical is to be understood as meaning an organic radical which does not lead to the formation of an OH group or NH 2 group linked to the Si atom in the presence of water.
  • the nonhydrolyzable radical R 1 is preferably selected from a group comprising substituted C 1 -C 30 -alkyl, in particular C 5 -C 25 -alkyl, and substituted C 3 -C 8 -cycloalkyl.
  • radical R 1 is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, s-butyl, t-butyl, pentyl, hexyl and cyclohexyl, preferably methyl, ethyl or propyl.
  • the at least one functional group Q 1 which may be contained in the organic non-hydrolyzable group, preferably includes an amino group, a monoalkylamino group or substituted or unsubstituted silyl group, an aryl group, especially a phenyl group, and a hydroxy group.
  • Typical compounds of general formula (I) which can be used in the primer layer are e.g. Bis (3-trimethoxysilylpropyl) amine, aminopropyltrimethoxysilane, aminopropyltriethoxysilane, 3-aminopropylmethyldimethoxysilane, 3-aminopropylmethyldiethoxysilane, N- (n-butyl) -3-aminopropyltrimethoxysilane, N- (n-butyl) - 3-aminopropyltriethoxysilane, aminoethylaminopropyltrimethoxysilane or aminoethylaminopropyltriethoxysilane.

  • the primer layer is preferably applied to a resin layer of a conventionally produced wood-based panel.
  • the resin layer can - but does not necessarily have to be sanded - before applying the primer layer; this depends on the nature of the resin layer.
  • the advantage of sanding the resin layer prior to application of the primer layer is improved adhesion of the primer layer to the resin layer.
  • the resin layer is composed of a formaldehyde resin as a polycondensate, in particular a melamine-formaldehyde resin, a melamine-urea-formaldehyde resin or urea-formaldehyde resin.
  • the resin layer can be arranged directly or directly on the surface of the carrier plate.
  • the resin layer can also be applied to a decor paper, which in turn is arranged on the support plate. It is also conceivable that the resin layer is applied to a directly on the support plate printed decor layer.
  • the resin layer may have various additives such as natural or synthetic fibers, flame retardants, dyes or abrasion-resistant particles. In general, various variants of the resin layer provided on the carrier plate are conceivable.
  • a particularly good adhesion of the primer layer to the resin layer is effected, which is particularly caused by the specific substituents.
  • the OH group may undergo a preferential interaction with the matrix of the resin layer.
  • a mixture of silanes of the general formula (II) can also be used.
  • the non-hydrolyzable radical R 2 is preferably selected from a group comprising substituted C 1 -C 30 -alkyl, in particular C 5 -C 25 -alkyl, substituted-substituted C 2 -C 6 -alkenyl, substituted C 3 -C 8 -cycloalkyl and substituted substituted C 3 -C 8 cycloalkenyl.

  • the functional group Q 2 accordingly advantageously has a radical with a double bond or an epoxide group which can be activated and polymerized by means of UV radiation. This allows hardening of the topcoat layer by means of UV irradiation.
  • Typical compounds of general formula (II) which may be used in the topcoat layer are methacryloxypropyltrimethoxysilane (MPTS), aminoethylaminopropyltrimethoxysilane, silanes having an epoxy functionalization such as glycidyloxypropyltriethoxysilane, or silanes having a vinylfunctionalization such as e.g. Vinyltrimethoxysilane.

  • the present wood-based panel has no so-called polishing effects, which typically occur in the production or use of very matt surfaces.
  • Polishing effects for example in the form of shiny spots, occur, for example, when cleaning conventional matt surfaces with a soft cloth (polishing) or when sliding furniture with felt glides over a floor covering with a corresponding surface.
  • These glossy spots can no longer be removed and, in addition to the matte surface of the surface of the utility object, are particularly easily recognizable, as a result of which the visual impression of the product is very damaged.
  • conventional matte surfaces have not been able to secure any relevant market share in the past, although the surface has been found to be haptic as well as soft general impression is perceived as very pleasant.
