Definitions

  • the invention relates to a coating for moisture-tight sealing of surfaces, in particular of
  • DE - A 29 20 658 discloses a method for applying a multi-layer protective layer on concrete walls and similar surfaces, wherein an adhesive coating composition is first applied, in which an elastic plastic film is embedded. An insulation layer and a subsequent protective layer are applied over this sealing layer.
  • a method for producing seamless, homogeneous and pore-free roof coatings is also known.
  • a synthetic resin melt based on polyolefins is applied to the surfaces to be sealed, with drying oils added in 5 to 10 parts by weight, e.g. Post-harden polybutadiene oils on the surface by oxidative crosslinking, but the enamel remains below the surface plastic.
  • this synthetic resin enamel can be applied without a primer and can also be repeatedly melted over the known polyurethane coating compositions.
  • the application of the coating according to DE-A-23 14 750 takes place in the same way as with bitumen in the hot-melted state at about 150 to 240 ° as a pourable and / or spreadable mass.
  • heating the enamel is very expensive in terms of energy consumption and working time and increases in the cold or even frosty season, in which the relatively thinly applied enamel cools down immediately after application.
  • the invention has for its object to provide an easy-to-process coating for sealing surfaces, which leads to an extremely durable, absolutely dense layer formation and is also resistant to mechanical influences.
  • This coating ace is easy to process without additional energy expenditure and ensures hermetic sealing of the roof surfaces and other concrete surfaces.
  • the coating is also suitable for coloring facades by coloring or mixing in additives.
  • the consistency of the underlayer can be anything from viscous to viscous adjust and thus adjust to the specific requirements, such as the flexibility and elasticity of the coating.
  • FIG. 1 is a perspective view of a portion of a flat roof in section
  • La shows a simplified version of the coating according to Fig.l
  • FIG. 2 shows a detail which is outlined in dash-dot lines in FIG. 1,
  • Fig. 3 shows a further detail of the invention
  • Fig. 4a shows the detail X, which is circled by dash-dotted lines in Fig. 4 and
  • FIG. 5a-c different views, partly in section, of the structural material used in the embodiment of the invention.
  • Fig. 6 shows a coating of a road bridge. Best mode for carrying out the invention:
  • a ceiling 22 primarily made of concrete, extends between vertical ones
  • Ceiling 22 can be provided with openings 10, 11 through which, for example, antennas or water drainage pipes can be guided.
  • the synthetic resin 3 used for this purpose which is preferably formed by the synthetic resin "Alkydal F68" from Bayer AG, is essential for the coating and sealing.
  • This synthetic resin is a long-oil, low-viscosity alkyd resin based on drying vegetable fatty acids, eg based on soybean oil with an oil content / triglyceride of approx. 66% to 69% and a proportion of phthalic anhydride from approx. 22% to 25%, an acid number 10 and a spec. Weight from approx. 1.04 to 1.06 g / cm3.
  • the resin shows a positive Storch-Morawski reaction and has an OH content of approx. 1.0% based on solvent-free resin.
  • the run-out time is approx. 65 seconds from a 4 mm DIN beaker at 20 ° C. according to DIN 53 211.
  • a preferred viscosity for the purposes of the invention is obtained when diluted to 75% with white spirit.
  • the synthetic resin can be processed down to low temperatures without any reduction in quality, and without additional heating devices. In addition, it penetrates into the pores and cavities of the concrete, for example, so that in addition to the sealing, there is a perfect one Adhesion with, for example, insulation or step plates placed thereon results.
  • This synthetic resin is normally used for paints and anti-rust paints, with larger quantities of drying agents being added in order to achieve the thorough drying required for paints.
  • the synthetic resin or the synthetic resin mixture should be such that the thickness of the coating should be selected in such a way that no drying or hardening occurs, but a thin, tough skin on the surface that comes into contact with air forms with a thickness of the order of 0.1 m, under which a viscous to tough synthetic resin mass with a thickness of approx. 3 to 6 mm, preferably approx. 4 to 5 mm, also remains in the long term.
  • a viscous to tough synthetic resin mass with a thickness of approx. 3 to 6 mm, preferably approx. 4 to 5 mm, also remains in the long term.
  • the covering dry layer serves to reliably repel any water, snow, ice and hail standing on it and to prevent shrinking of the viscous resin underneath.
  • 0.05 to 0.2%, preferably between 0.05 to 0.1%, drying agent and at least 0.3%, preferably at least 0.5%, color pigments are added to the solvent-free synthetic resin, the latter contributing to reduce the shrinkage of the soft to liquid resin.
  • Suitable metals, in particular Co, Sn and Ba, can be used as desiccants for this purpose.
  • the synthetic resin 3 is poured on and distributed over a layer thickness of approx. 5 mm, so that the synthetic resin penetrates 3 to approx. 1 mm into the concrete surface, pores and voids are filled and condensation on the concrete surface is excluded.
  • 3 insulating materials 4 i in the form of mats or plates are placed directly on the applied and melted synthetic resin layer.
  • this main insulation layer should have the lowest possible compression behavior.
  • the insulation 4 preferably has a density in the order of 30 to 40 kg / m3 and fiber insulation is compressed on the top or provided with its own hard layer. A small distance, for example in the order of 5, must be maintained from all vertical surfaces, so that there is an uninterrupted gap at the edges and feedthroughs which is filled with the resin 3 until it overflows.
  • the most important sealing layer in relation to precipitation is now produced by pouring further synthetic resin 13 in the composition described above onto the insulating material 4 and distributing it without gaps using the standard notched trowel.
  • This application of two layers below and above the insulating material 4 ensures that steam does not penetrate into the insulating material 4 from below from the living room or operating room, nor from above, so that it retains its insulating effect a duration.
  • cover plates 12 which are resistant to treading can now be let into this applied synthetic resin layer 13 and the roof structure can be completed by pouring out the joints.
  • additional filler layers can also be inserted according to FIG.
  • a net 5 for extended roof use preferably a net 5, for example made of polyethylene with a thread thickness of 2 mm and a mesh size of 8 mm.
  • the net 5 sinks into the synthetic resin composition 13 and is covered with further synthetic resin, so that the desired layer thickness again results in the order of magnitude between 3 and 8 mm, preferably in the order of 5 mm, as shown enlarged in FIGS. 2 to 4 a.
  • This possibility of maintaining a distance can also be achieved, for example, with quartz sand, fleece or with their absorbent fillers.
  • the next layer in FIG. 1 consists of structured floor elements 7, for example made of polyethylene or styrofoam at a height of 30 to 80 mm, preferably of the order of 50 mm.
  • structured floor elements 7 are to have through openings 25 which are guided from a flat top of the elements to recesses 26 which are recessed into the floor elements from the underside. Between the recesses 26 there are thus feet 27 which penetrate into the still liquid synthetic resin layer 13 when placed on it and are finally supported on the net 5, so that it is ensured that between the bottom of the feet 27 and the top of the insulating layer 4 the sealing synthetic resin layer remains uninterrupted.
  • the areas 8 and 9, from FIGS. 1 and 2, represent the known substructure variants for greening.
  • FIG. 1 a a simplified embodiment of the flat roof according to FIG. 1 is shown, wherein cover plates 12 are inserted into the second synthetic resin layer 13 and, compared to FIG. 1, the layers 8 and 9 and the structural elements 7 are dispensed with Synthetic resin layers 3 and 13 are interspersed with quartz grains 50 with a grain size of 0.6-1.2 mm, which, in addition to the optical configuration in the synthetic resin layer 13, results in an increase in the strength of the synthetic resin layer and can make covering by cover plates 1 unnecessary.
  • FIGS. 2 and 4 show these critical points in more detail.
  • a spacer 16 with feet 6 can be seen from Fig. 2, which is used all around before the application of the floor elements 7 and a gap of e.g. 5mm forms, which is filled with synthetic resin mass 3, the lower edges of the spacers 16 are embedded in the synthetic resin layer 13 and the transitions are intensively coated with synthetic resin 3.
  • the spacers 16 are filled with synthetic resin 3 to such an extent that there is a fillet 17 at the top, which merges into the primer coat of the vertical wall 21, so that water penetration is absolutely prevented.
  • FIG. 3 on the left shows an alternative embodiment with a spacer 36 which is provided with a flange 37 which is placed on the insulating material 4 before the second synthetic resin layer 13 is applied.
  • drain pipe 10 is first inserted into the concrete ceiling 22 and fixed with joint filler 2.
  • the sleeve 47 is arranged such that its upper edge lies slightly below the surface of the first synthetic resin layer 3 after it has been applied, so that any precipitation can flow away.
  • the grommet 46 is then inserted (see also FIG. 4) and cast with synthetic resin 43.

Abstract

Un revêtement de scellement d'étanchéification de surfaces, notamment de toits plats, comprend une composition de résine synthétique qui ne sèche pas entièrement, avec une proportion minime de produit desséchant et éventuellement une proportion accrue de pigments. On applique sur une surface nettoyée une épaisseur suffisante de cette composition pour obtenir une couche de base fluide ou visqueuse sous une couche sèche visqueuse et élastique relativement mince. La résine synthétique est composée d'une résine alkyle longue en huile à faible viscosité à base d'acides gras de séchage d'origine végétale. Ce revêtement est facile à manipuler et assure une étanchéité stable à long terme des surfaces.
