Definitions

  • the invention relates to an overlay which is coated with a synthetic resin.
  • Overlays coated with synthetic resins, which are suitable for application to wood-based materials, are a common precursor in the production of coated wood-based materials. Due to the resistant surfaces resulting from the coating of the wood-based materials directly or through the application of resin-impregnated overlays, these wood-based materials used both in the living area (kitchens, offices, floors) and used for commercial purposes. In the context of this invention, all products made of wood or a mixture of wood and plastic are referred to as wood-based materials. Particularly typical wood-based materials are different types of fiberboard or chipboard.
  • antistatic agents mostly surfactants
  • these surfactants extract water from the ambient air.
  • the forming in the vicinity of the surfactants, thin molecular water film is sufficient to ensure a minimum charge balance.
  • This intrinsically simple and convincing active principle has in practice two decisive disadvantages:
  • the water film forming around the surfactants only causes a reduction of the surface resistivity by about one order of magnitude, ie to about 1 ⁇ 10 10 ⁇ to 1 ⁇ 10 11 ⁇ ,
  • the measured values, z. B. to EN 14 041 are required to classify surfaces as conductive, not achievable.
  • Another disadvantage is that the ambient air must have sufficient moisture to form a film of water.
  • the problem of static charge is just at low humidity. Antistatic agents do not work exactly when they are needed.
  • the core of the invention is the incorporation of electrically conductive, transparent particles in synthetic resin, preferably in transparent synthetic resin. This mixed with transparent, electrically conductive particles resin is then applied to an overlay. According to the invention, it has been found that a single layer of synthetic resin, which is mixed with small amounts of said particles, is sufficient to achieve a significant improvement permanently and independently of other parameters, such as ambient humidity To ensure the Ableitein, for example, to create a surface for a dissipative floor according to DIN IEC 61 340.
  • Transparent conductive particles are produced, for example, by applying metal oxides to carrier particles.
  • a mica particle doped with tin and antimony oxide is suitable.
  • Transparent particles may have a platy or spherical shape. Good conductivity and transparency as well as optimum conductivity is achieved with particles having a diameter of up to 25 .mu.m, preferably up to 15 .mu.m, preferably of up to 10 microns.
  • the electrically conductive, transparent particle is contained in only one layer of a multilayer synthetic resin structure on an overlay.
  • up to 15% by weight (% by weight) of electrically conductive, transparent particles are based on the solids content of the synthetic resin, preferably up to 10% by weight, more preferably up to 8% by weight of particles based on the Solid portion of the resin used.
  • a dissipative surface on an overlay is built up if at least one layer, that is to say up to 40 g / m 2 of a synthetic resin mixed with transparent, conductive particles according to the invention, is applied.
  • at least one layer that is to say up to 40 g / m 2 of a synthetic resin mixed with transparent, conductive particles according to the invention.
  • up to 25 g / m 2 more preferably up to 15 g / m 2 , advantageously up to 10 g / m 2 are sufficient.
  • the layer structure of the respective surface can easily exceed 100 g / m 2 in the case of a multilayer structure. Nevertheless, only one layer of the inventively particulate resin suffices to provide a surface having significantly improved conductivity.
  • a layer thickness on the substrate is sufficient Wood material board of up to 40 microns, preferably up to 20 microns, more preferably of up to 10 microns, to achieve in the walk test to EN 1815 a classification according to EN 14041 as a static surface, which ensures a Wegetzladung of less than 2 kV.
  • This value is achieved with the present invention on an applied, provided with particles of synthetic resin layer. It should be particularly pointed out that this is achieved largely independently of the ambient humidity, that is also at values of, for example, 25% relative humidity.
  • a reduction of the surface resistance to values of 2 ⁇ 10 08 ⁇ was achieved with the overlay according to the invention when using melamine resin which has been mixed with transparent, electrically conductive particles.
  • the electrically conductive, transparent particle is firmly anchored in the synthetic resin. It may therefore be contained in the outermost layer of a multi-layered surface. Surprisingly, however, the desired dissipation ability is also achieved if the layer containing the mentioned particle is used in a multi-layered surface structure, e.g. is covered by other resin layers.
  • a transparent synthetic resin is used, in particular a melamine resin.
  • a transparent synthetic resin is used, in particular a melamine resin.
  • This achieves an expansion of the fields of use of the overlays coated according to the invention, so that these are e.g. also suitable for work surfaces in the electronic industry. Panels are also often used for the design of wall surfaces, so floors, ceilings or walls.
  • the coating according to the invention proves to be advantageous, since the conductive surface is also suitable for at least partial shielding of electromagnetic fields. It thus helps to avoid interference from electrosmog.
  • the term "overlay” is understood to mean that a carrier made of paper or a synthetic fiber scrim is coated at least with a synthetic resin layer which has transparent, electrically conductive particles. Overlays are usually used for coating board-shaped wooden materials.
  • the at least single-layer surface coating of the overlay according to the invention has at least one synthetic resin into which the electrically conductive, transparent particles are mixed.
  • the synthetic resin may also contain fibers to form a so-called "liquid overlay”. That is, when using a "liquid overlay” can be dispensed with the use of the usual paper-based overlay. The liquid overlay is applied directly in liquid form to the surface of a wood material.
  • the multi-layered surface of plate-shaped wooden materials often also has a layer of coloring constituents, which is covered by transparent synthetic resin layers. Especially in the case of this surface structure, it becomes clear that the transparency of the electrically conductive particles abolishes restrictions on the use of the plate-shaped wood-based materials which hitherto existed.
  • An overlay with a basis weight of 40 g is guided by rollers through a per se known impregnation plant with Quetwalzendostechnik.
  • melamine resin with a solids content of 60% is introduced into the paper.
  • the overlay is passed through a pair of rollers on which excess synthetic resin is stripped off.
  • the paper thus impregnated, after intermediate drying, has a weight of 100 g / m 2 .
  • an additional melamine resin layer of 20 g / m 2 is applied to the top and bottom of the paper in a raster application work.
  • the top side applied melamine resin layer is associated with-related to the solids content of the melamine resin 8 wt .-% transparent, electrically conductive particles, namely with mica particles, which are doped with tin and antimony, and a diameter of approx 15 ⁇ m.
  • the overlay is dried after application of the second melamine resin layer.
  • the overlay is pressed on a high-density fiberboard on which decorative paper is already applied, under pressure and heat.
  • the resulting surface of the fiberboard has a surface resistivity of 3.0 x 10 08 ⁇ when tested for electrostatic behavior according to IEC 60093 and EN 1081. If such a coated fiberboard is used as floor, it is classified as "Ableitschreiber complicatboden” according to DIN IEC 61340 -4-1: 1997 or as "electrostatic dissipative floor covering" according to EU 14041: 2004 -12-20. This classification was previously unattainable when using melamine resins for surface coating of floors.
  • the test according to EN 1815 results in a so-called person voltage of 1.8 kV on an insulating pad for a person in rubber soles.
  • the coated with the above overlay fiberboard is classified as a conductive floor, because the personal voltage of 2 kV is well below.
  • a decorative paper 2 intended to be used for a table top is made by impregnating a backing paper with a melamine resin decorative print.
  • a melamine resin layer 3 is added, which is based on the solids content of the melamine resin with 10% by weight of the particles 4 described in example 1, and that with 40 g / m 2 is applied to the preimpregnated paper 2.
  • the decorative paper with a conductive top surface thus produced is pressed onto a chipboard.
  • This chipboard 1 is suitable for use as a worktop, in particular in the electronic industry, since the surface resistance of the melamine resin coating thus produced is 10 07 ⁇ to 10 09 ⁇ . Sensitive electronic components that are damaged or destroyed by stronger electrical discharges can be stored or processed on these easily and inexpensively manufactured surfaces.
