Definitions

  • the present invention relates to an insulating board made of a calcium silicate hydrate-based base material and a method for producing an insulating board.
  • the building sector is still the largest consumer of energy in Germany, ahead of the transport and industry sectors, and contributes greatly to the CO2 emissions in our country. It is generally acknowledged that the building sector has considerable potential for saving energy, which must be exploited against the background of climate change and the increasing scarcity of fossil fuels in order to sustainably and significantly increase energy efficiency. In addition to the increasing use of regenerative energy sources for building heating and water heating, a long-tracked and state-subsidized way of doing so has been to gradually increase the structural heat protection. With the introduction of the Energy Saving Ordinance (EnEV) in 2002 and subsequent adjustments, very high standards are already being achieved in new buildings today. However, the very ambitious goal of creating energy neutrality in the building sector using renewable energies in relatively short periods of time can only be achieved if existing properties are comprehensively and energetically renovated.
  • EnEV Energy Saving Ordinance
  • thermal insulation composite systems which are used in the course of energy renovation measures are applied to the existing facades.
  • a facade insulation is subject to increasing criticism, as it is no longer regarded as uncritical from a construction-material point of view, as well as negatively perceived from an architectural perspective. Accordingly, the acceptance of such external insulation decreases, especially since they are usually not considered for listed buildings.
  • the buildings are "enlarged" by the application of a facade insulation, which in close development, taking into account minimum distances to neighboring properties or neighboring buildings can lead to the fact that a facade insulation eliminates as an energy renovation measure.
  • U-value heat transfer coefficient
  • none of the currently available interior insulation systems is capable of meeting the requirements of economic efficiency and / or room climate and / or application-related properties resulting from the current Energy Saving Ordinance, such as processability, the possibility of retrofitting of pipes and Pipes, easy way of putting dowels or nails, etc., to fully meet.
  • the object of the invention is to provide an innovative, cost-effectively producible composite material as a thermal insulation material and a method for the production thereof, which has the indispensable property of capillary conductivity and the other positive features of mineral building materials, such as room climate-regulating effect, adequate carrying capacity, incombustibility and sustainability, combines with the superior insulating properties of modern organic foams and thus overcomes the known from the prior art disadvantages of êtdämmsystemen.
  • An insulation panel according to the invention is characterized by a calcium silicate-based matrix material, in which polymer foam particles are embedded, which have a specific thermal conductivity ⁇ , which is lower than the specific thermal conductivity ⁇ M of the matrix material.
  • the material concept envisages as the matrix material of the insulation board a highly porous calcium silicate hydrate of low density into which polymer foam particles having a low thermal conductivity are introduced in the course of production, which have sufficient thermal and chemical stability.
  • the process originating from the technology of hydrothermally hardened building materials requires Thus, insulation boards can be produced, which achieve a comparable insulating effect as known from the prior art aerated concrete panels at a lower thickness. As a result, the space required for efficient energy renovation in an internal insulation system can be reduced.
  • the insulating board according to the invention can be "harmless" and physically harmless like an aerated concrete slab.
  • the insulating slat according to the invention can be processed by means of simple tools on site, ie in the property to be energetically rehabilitated, so that both a blank
  • the insulating material according to the invention is conventionally surface-workable, so that trowelling and plastering with possibly subsequent painting of the insulating board is possible without difficulty.
  • additive and / or stabilizer are provided which prevent floating of the polymer foam particles in the production of the insulation board.
  • a largely uniform distribution of the polymer foam particles can be achieved, so that a largely homogeneous structure is formed.
  • concentrations of the polymer foam particles on the one hand and areas with low concentration of the polymer foam particles.
  • this ensures a uniform insulation effect of the insulating lath, on the other hand, it prevents the occurrence of great inhomogeneity with regard to the strength and the fracture behavior of the insulating board during later processing.
  • the strength of the insulating board can be increased in such a way that a tear-resistant insertion of nails and dowels into the insulating board is possible.
  • the thermal conductivity ⁇ of the polymer foam particles is less than 0.035 W / (m * K). Below this value, a significant improvement of the thermal insulation compared to aerated concrete plates (mineral foam boards) without additives is possible. It is particularly advantageous if the polymer foam particles have a thermal conductivity ⁇ of less than 0.025 W / (m * K), since such polymer foam particles allow a further reduction in the thickness of the insulating board with the same insulating effect.
  • an insulation panel according to the invention has a thermal conductivity ⁇ of less than 0.04 W / (m * K).
  • a heat transmission resistance R of> 2 m 2 * K / W can be achieved with a thickness of the insulation panel of eight centimeters, which is acceptable as far as possible in relation to the loss of space.
  • a heat transfer coefficient of ⁇ 0.39 W / m 2 * K can thus be achieved, which would be permissible under the currently valid Energy Saving Ordinance (EnEV).

  • the polymer foam particles have a density of less than 40 kg / m 3 .
  • the polymer foam particles absorb and / or reflect infrared radiation.
  • the heat resistance of the insulation board can be further increased.
  • radiation in the wavelength range of 2000 cm “1 to 4000 cm “ 1 is absorbed or reflected, since in this frequency range, a large part of the thermal radiation is at terrestrial temperatures.
