Definitions

  • the invention relates to an insulation board made of a wood-material-binder fiber mixture in which the mixture is added to an additive of a thermally stable core, wherein the core is provided with a thermally activatable coating and a method for producing an insulation board.
  • insulating materials from fibers, for example wood, flax, hemp or wool fibers or the like, optionally with the addition of thermoplastic binder fibers, is known.
  • the production of these insulating materials and nonwovens takes place in a dry process, for example with aerodynamic nonwoven laying processes with spatial orientation of the fiber-binder fiber matrix in a fiber loosening and distributing the fiber and subsequent thermal solidification of the fiber-binder fiber matrix in a H exertluft matströmungstrockner. This is for example in the DE 100 56 829 A1 described.
  • the production of the insulating panels can also be carried out by wet process with a subsequent hot-pressing process.
  • binder fibers which are usually made of a polyester or a polypropylene core with thicknesses of 2.2 to 4.4 Detex and are added in a proportion of up to 25 weight percent. Since the costs for these binder fibers are relatively high compared to wood fibers, such insulation materials are comparatively expensive. Furthermore, the addition of binder fibers has only a limited effect on improving the compressive stiffness.
  • An optimum density for a wood fiber board as a plaster base plate is about 100 kg / m 3 . Higher densities have a negative effect on the thermal conductivity of the insulation board in such a way that the required thermal conductivity group WLG 040 is not reached, on the other hand increased stability is achieved.
  • Object of the present invention is to provide an insulation board, an additive for an insulation board and a method for producing an insulation board, with which the compressive rigidity and structural strength of insulation boards of wood materials, especially wood fibers, can be increased inexpensively with low densities.
  • this object is achieved by a generic insulation board from a wood-material-binder fiber mixture, wherein the core is formed as granules.
  • the core consists of perlite or a thermoset material, which has an improvement in the moisture resistance of the insulation board due to the hydrophobic properties of the additive. This results from a reduced mass of hydrophilic wood materials, in particular wood fibers, corresponding to the addition of the additive.
  • the core is formed as a granulate in order to come into contact with as many wood-based components or wood fibers as possible as well as binder fibers.
  • fine-grained granules or fine particles of bituminized perlite, of different thermoplastic groups, thermoplastically coated thermoset groups or comparable particles with a thermally stable core and a thermally activatable or thermoplastic shell are added to the dry wood fiber / binder mixture.
  • the particle sizes of the additive are between 0.3 and 2.5 mm.
  • the proportion of the additive based on the total mass of the wood-material-binder fiber mixture is at least 20%, but may also be 40% or more.
  • the additive is homogeneously distributed within the wood material-binder fiber mixture in order to ensure a uniform pressure and structural strength of the insulation board.
  • the additive is hydrophobic, so that in addition to the improved compressive rigidity, a higher moisture resistance of the insulation board is achieved.
  • the insulation board preferably has a bulk density of more than 20 kg / m 3 , but may also have a bulk density of over 100 kg / m 3 , on the one hand to have optimum strength and on the other hand optimum thermal conductivity, so that when used as a stable plaster base a ensures good insulation is.
  • the proportion of binder fibers can be reduced to about 10 percent by weight, based on the total mass of the insulation board, which reduces the cost of the insulation board.
  • An additive to improve the compressive stiffness and microstructure improvement of insulation boards from a wood material-binder fiber mixture provides a thermally stable core and a thermally activatable coating, so that by energy supply both the wood materials and the binder fibers can be connected to the additive.
  • the heat is supplied for example by a H exertluft fashionströmungstrockner, a superheated steam or HF heating. Other heating options are also provided, for example by heated press plates.
  • the thermally activatable coating is a thermoplastic to effect cross-linking of the wood materials and binder fibers with the additive.
  • the coating may completely enclose the core, alternatively, only a partial coating of the surface of the core is provided.
  • the core consists of a granulate, for example of perlite or another mineral base material, wherein alternatively to a mineral material, the core may also consist of a thermosetting plastic. It is also possible, in coordination with the process control, to use a thermoplastic which remains dimensionally stable at the existing temperatures.
  • the additive may be a mixed plastic, which in addition to thermosetting and thermoplastic shares.
  • mixed plastics are, for example, products of the dual system (DS) with average proportions of 50 to 70% polyolefins, 15 to 20% polystyrenes, 5 to 15% PET and 1 to 5% other packaging plastics.
  • DS dual system
  • Such mixed plastics are produced in dry treatment processes, in particular mixed plastics from household waste are used.
  • the starting material is first comminuted in a comminution stage, magnetic substances are removed from the comminuted material, and the comminuted material is thermally agglomerated or compacted under pressure, ie, press-agglomerated. During the agglomeration process, volatiles, water vapor, ash and paper can be sucked through suction devices.
  • thermoplastic plastic components e.g. Polyethylene (LDPE, HDPE) and duroplastic plastic components, e.g. Polyester or polyurethane
  • LDPE Polyethylene
  • HDPE high density polyethylene
  • duroplastic plastic components e.g. Polyester or polyurethane
  • a thermoset core of, for example, polyurethane is completely or partially surrounded by a thermally activatable, thermoplastic shell of, for example, polyethylene, or a thermoplastic core which melts at high temperatures is surrounded by a shell which melts at low temperatures.
  • Such agglomerated mixed plastics have a sufficiently high proportion of thermally activatable (thermoplastic) shares and thermosetting constituents and are particularly suitable for this reason as an additive for improving the compressive stiffness and structural improvement and / or as a binder for an insulation board, since the thermoplastic shell of the additive a sufficient temperature supply, for example, in a hot pressing process is thermally activated.
  • thermally activatable (thermoplastic) shares and thermosetting constituents are particularly suitable for this reason as an additive for improving the compressive stiffness and structural improvement and / or as a binder for an insulation board, since the thermoplastic shell of the additive a sufficient temperature supply, for example, in a hot pressing process is thermally activated.
  • such agglomerated mixed plastics can be added to wood material fibers and known binder fibers in insulation product production, since the agglomerated mixed plastics have thermally activatable constituents which are activated under pressure and temperature for the production of insulating boards, the thermoset cores or the thermoplastic cores remaining stable.
  • agglomerated mixed plastic for the production of the baffles, improved compression stiffness and transverse tensile strength values of the panels can be achieved without having to increase the proportion of expensive binder fibers (with polypropylene core and polyethylene shell).
  • the increase in the strength properties is possible only by adding inexpensive, agglomerated mixed plastics, which originate from the dual system.
  • the additive is hydrophobic to improve moisture resistance.
  • the method for producing an insulation board with a wood-material-binder fiber mixture provides that the mixture is an additive with a thermally resistant formed as granules core and a thermally activatable coating is added.
  • the thermally activatable coating is activated with the addition of heat, so that the wood material-binder fiber mixture and the additive are crosslinked with each other.
  • an insulation plate is provided which is located in the optimum density range of about 100 kg / m 3 and thereby has sufficient compressive strength and transverse tensile strength while moisture resistance.
  • the wood materials and the binder fibers are mixed in an aerodynamic web-forming machine, then the additive is mixed in a separate web-forming machine.
  • the spatial orientation of the fiber matrix is carried out, whereby this takes place in a separate aerodynamic web-forming machine.
  • the coating of the core is in activated hot air stream, alternative activation methods, for example by heated rollers, RF heating or infrared radiators are also possible.
  • a uniform formation of the structure of the insulation board is effected by a homogeneous distribution of the additive within the wood-material binder fiber mixture.
  • the figure shows the embedding of an additive in a wood fiber binder fiber matrix.
  • wood fibers 1 and binder fibers 2 are homogeneously mixed in a first aerodynamic web forming machine.
  • wood fibers 1 other wood materials, such as wood chips or the like, can be used, for example, alternative raw materials such as hemp, wool, flax or other renewable resources.
  • a tempering additive which consists of a core 4 with a thermally activatable coating 3
  • This thermally activatable coating 3 may for example consist of a thermoplastic material. This coating 3 can either completely surround the core 4 or be arranged only partially on its surface.
  • the additive 3, 4 is added to the dry mixture of wood fibers 1 and binder fibers 2 as a fine-grained granules or as particles of corresponding materials, such as coated thermoplastic groups or thermoplastic-coated thermosets.
  • the grain sizes of the additive 3, 4 should be 0.3 to 2.5 mm, preferably 0.5 to 2 mm for this purpose.
  • the proportion of the additive in the total mass of the insulating board should be at least 20%, but also values of over 40% are possible.
  • the admixture of the additive 3, 4 and the spatial orientation of the fiber matrix takes place after the mixing of the wood fibers 1 and binder fibers 2 in a separate, second aerodynamic web-forming machine.
  • the proportion of binder fibers 2 can be reduced to 10% of the total weight.
  • the particles of the additive 3, 4 are homogeneously distributed within the matrix of the wood and binder fibers 1, 2.
  • the activation takes place advantageously in a hot air flow dryer, so that form by the heat supplied, the thermoplastic shell 3 of the core 4 of the additive particles additional contact points to the wood fibers 1 and the binder fibers 2.
  • This provides a pressure-stiff fiber-binder additive matrix having improved structural strength.
  • the tempered with the additive 3, 4 insulating materials can be used as a thermal insulation in the outdoor area, eg. B. for thermal insulation systems and as impact sound insulation in the floor area, z. B. be used under laminate or engineered parquet floors.
