Definitions

  • the invention relates to a dimensionally stable, dimensionally stable visible component for installation on walls and roofs, consisting of an insulation board with a firmly connected cover.
  • the invention is based on the object of sealing against surface water, heat-insulating, mountable sight Finding a component with a lively surface structure that maintains a clear appearance even after prolonged use and remains fully functional in the long term.
  • the cover consists of a heap of coarse-grained minerals with a grain size of 3 - 30 mm, provided with 3 to 25 wt. -% and fine-grained minerals with a grain size of 0.005 to 1 mm are filled.
  • Another advantage of the cover is the extensive resistance to flying flames and radiant heat, which significantly reduces the risk of fire with heat-insulating plastic foam panels. Striking is also the clear, clean appearance of the protruding minerals, which show little contamination even after long use.
  • Thermal insulation boards of a conventional type are suitable for the invention. Suitable are e.g. Thermal insulation boards based on polystyrene foam and those based on polyurethane foam. In a preferred embodiment, thermal insulation boards are used, which is a combination element consisting of an inner core made of rigid polystyrene foam and outer cover layers made of cement-bound wood chips.
  • the synthetic resin binders to be used according to the invention are preferably those which have a low tendency towards thermoplasticity.
  • Two-component binders e.g. based on epoxy or polyurethane resins are used, preference being given to low-solvent or solvent-free combinations.
  • Catalysts can be used to influence the curing rate, with tertiary amines and metal compounds such as e.g. Dibutyltin dilaurate can be used.
  • Fillers are used for the joint filler, as are also used in the paint and paint sector.
  • slate flour, calcium carbonate flour and quartz flour are suitable for this purpose.
  • the binder consists of a synthetic resin containing isocyanate groups, in particular of a component which reacts under atmospheric humidity.
  • Binders which contain isocyanate groups and which undergo a crosslinking reaction during and after processing in contact with atmospheric moisture have proven to be particularly favorable.
  • These can be derivatives of diphenylmethane diisocyanate and also derivatives of aliphatic polyisocyanates such as e.g. Hexamethylene diisocyanate and isophorone diisocyanate.
  • the coarse-grained minerals have a grain size between 5-15 mm.
  • Quartz has proven itself as a mineral substance. Coarse-tipped or rounded calcium carbonate fractions are also used. Almost all minerals are suitable, so that the selection can be made according to the desired appearance.
  • the fine-grained minerals consist of silicate hollow beads with a specific weight of less than 1 g / cm 3 and a grain size of 0.005-0.5 mm.
  • This material forms a tight bond with resins and is therefore also suitable for joints between the exposed building elements.
  • the visible surface is provided with a polyurethane seal.
  • the visible surfaces can be sealed, with color-stable, weather-resistant polyurethanes having proven particularly effective.
  • the resin-impregnated, coarse-grained minerals of 10 - 40 mm thickness are applied to one side of the insulating plate with a thickness of 10 to 80 mm using a doctor blade and evenly distributed. If the solidification of the binder no longer allows the coarse-grained minerals to move, the filling quantity is introduced into the joints with even distribution. The surface is then brushed so that the individual minerals come out plastically. The plate may then harden after sealing and can then be transported to the construction site.
  • the panels according to the invention can be assembled, the type of thermal insulation panels used being decisive for the assembly.
  • Laying on wooden or aluminum moldings done for thermal insulation with cement-bonded wood chip layers can be a bonding with the usual mineral or synthetic resin adhesives done - for bare boards based on thermal insulation materials that can.
  • the joints between the components are closed with the same joint mortar as was used for the second layer of the building boards according to the invention.
  • the use of the building boards according to the invention for covering terraces or roofs is interesting.
  • a complex process is nowadays accepted for covering terraces over inhabited rooms, whereby concrete slabs are loosely stored on the rubber pads over the waterproofing to ensure drainage below the concrete slabs.
  • This construction is complex, heavy-duty and sensitive to constipation.
  • the panel thickness must be dimensioned so that there is sufficient pressure resistance. A layer thickness of 20 mm is sufficient for this, which leads to a considerable weight saving compared to the conventional cover.
  • the processing is done by pouring and spreading with spatulas.
  • the processing time is 30-40 minutes, while the hardening takes place within 24 hours.
  • This combination is not suitable as a component due to the low dimensional stability, which leads to bulging of the plate after only a few days.
