Definitions

  • the present invention relates to a method and an apparatus for applying multicomponent resins to porous, solid materials to be solidified, in particular bulk materials to be solidified, which are optionally subsequently compacted by shaking etc.
  • Typical materials of this type are, for example, the ballast beds of railroad tracks, additional fine-grained stones on such ballast beds, but also sand and gravel fillings in road construction, which are to be glued together without losing their water permeability.
  • the bonding is carried out in particular in the transition zones between soft and firm areas in accordance with the applicant's German patent application P 39 41 141.9.
  • AT-B-0 380 412 describes a complicated device and a complicated method which, parallel to the mixer and material pipe, requires a circulation system in which the adhesive mixture has to be circulated during interruptions in the delivery of the adhesive mixture.
  • a retarder must also be added to this circuit.
  • retarder and hardener in the right amount and at the right time is extremely difficult to control. If this method can be used at all, only mixtures with relatively long pot lives can be used. It should also be noted that this process never uses completely homogeneous mixtures.
  • the addition of more or fewer retarders on the one hand and more or less hardener on the other hand ultimately results in inhomogeneous end products.
  • the method can only be used in a stationary manner.
  • EP-A-0 180 118 describes a material for the installation of rails, in particular tram rails, the installation material consisting of a mixture of a tough and hard plastic mass and grains and the grains having a multiplicity of self-contained cells in their interior.
  • the grains are preferably made of fired clay and have a multitude of small air cells (expanded clay) that are closed inside.
  • This material is intended to shield the rail track from the other hard and solid surroundings in a sound-insulating manner and thereby reduce sound transmission in the living area.
  • the grains are completely surrounded by the two-component adhesive. The process is unsuitable for coating a granular material such as gravel with a thin film, which then adheres selectively, but leaves the main volume of the spaces free.
  • the setting reaction should only take place after a sufficient layer depth of the bulk material has been covered with the multi-component resin, but has not been filled to its full volume. Since multicomponent resins are generally very reactive substances that can irritate the skin and mucous membranes during processing, the formation of spray mists should be suppressed or avoided entirely. When processing in tunnels or even closed rooms, you should also work solvent-free. This requirement basically also applies to processing outdoors, since the solvents that evaporate immediately or later lead to an environmental impact that should be avoided if possible. Nevertheless, the application of the multi-component resins must be quick, easy and safe to carry out in order to keep material and labor costs as low as possible. Furthermore, the device is to be used in a simple and reliable manner at the construction site, for which purpose a simple, compact and easy-to-use device must be provided.
  • This versatile, difficult and sometimes contradicting task can be solved surprisingly simply by separating the components from each other a pressure of 30 to 200 bar to a mixing chamber, mixed turbulently in the mixing chamber and the mixture with a pressure of 2 to 6 bar in the form of a flat curtain-like film applied laminar to the material.
  • the viscosity of the mixture is increased to 300 to 1000 mPas, but the surface tension is reduced.
  • the components and additives should be solvent-free from the start. Furthermore, the addition of solvents should be avoided as far as possible.
  • Flat jet nozzles which operate at relatively low pressure are particularly suitable for producing a flat curtain of the laminar emerging mixture.
  • Suitable flat jet nozzles are available, for example, from Spraying Systems Kunststoff GmbH, Hamburg, under the names FlatJet® nozzles and FloodJet® nozzles.
  • these flat jet nozzles provide a flat curtain of fine droplets with a considerable proportion of spray mists.
  • the individual components of the multicomponent resins must be mixed as quickly and as intensively as possible before being discharged from the flat jet nozzle, the amount of the mixture produced in each case being kept as small as possible in order to keep material losses as little as possible during work interruptions.
  • the components must therefore be mixed with one another in a turbulent manner in the mixing chamber.
  • Static mixers have proven particularly useful. These are relatively short tubes that have left-hand and right-hand helixes one behind the other, thereby ensuring turbulent flow and perfect mixing of the components.
  • the feed lines for the individual components to the static mixer must be under relatively high pressure. Pressures between 30 and 200 bar (preferably 50 to 150 bar) have proven successful. This relatively high pressure is reduced so much within the static mixer that the finished mixture only emerges into the flat jet nozzle under a residual pressure of 2 to 6 bar.
  • the residence times of the multi-component resins in the mixing chamber or the static mixer are considerably shorter than the so-called pot times of the finished mixtures.
  • the mixture applied to the bulk goods according to the invention thus retains its relatively low viscosity long enough to spread and wet through a sufficiently thick layer of the bulk goods.
  • each of the separate feed lines for secure the components with check valves.
  • the compressed air empties the supply line into the mixing chamber and from there to the flat jet nozzle. There, after a short time, a flat curtain of a liquid / air mixture emerges, which can be noticed both visually and acoustically and should lead to the interruption of the entire processing process.
  • the device thus consists of the separate supply lines for the components under high pressure, a mixing chamber and a flat jet nozzle for, compared to the pressure in the supply lines, low pressure of 2 to 6 bar.
  • the device preferably has separate compressed air lines which open into the supply lines for the components.
  • the supply lines for the components and the compressed air lines are each secured by check valves, so that unintentional penetration of one or all components into parts of the device other than the mixing chamber and the flat jet nozzle is avoided.
  • the device When using static mixers, the device is relatively simple, light and therefore easy to handle manually.
  • the device is preferably supplied via flexible hoses. With a two-component resin, two hoses are sufficient for the components and one hose for the compressed air.
  • Preferred multi-component resins are epoxy resin adhesive and polyurethane resin adhesive.
  • a third or fourth liquid component can also be metered in, particularly if the surface tension, the viscosity and the reaction time are to be adapted to the particular situation or these additional components lead to a reduced durability of the main components when premixed.
  • Additional components can also be flame retardants, defoamers, suspensions of color pigments, etc., which should only be used at certain points or particularly critical areas.
  • FIG. 1 a device according to the invention for applying a two-component resin with components A and B is shown schematically.
  • the stone bed is applied to the track from a narrow grain size range below 63 mm, preferably below 30 mm in diameter, and solidified by spraying with a spreading multi-component epoxy resin adhesive.
  • the covering produced by this process has a relatively large amount of cavity, but is nevertheless solidified because the spreading adhesive extends around the grains and thus always reaches the points of contact of the grains with one another, where it connects them after hardening , but before that, if necessary, overflows down to the next grain etc. - always along the grain surfaces and not filling the cavities.
  • the grain size range which is far below that of the ballast bed that may be present - preferably less than 25 mm, better less than 20 mm - which, depending on whether the greater emphasis is placed on sound absorption or on cleanability, is more or less so, but also for both functions can be chosen uniformly.
  • the grain size range will generally be limited to a grain size ratio of 1: 2 to 1: 3 (smallest grain to largest grain).
  • the grain sizes 2 to 4 mm, 4 to 11 mm and 8 to 16 mm have proven to be expedient.
  • the stone fill can also be applied several times in different layers. If the grain size increases from bottom to top, this improves sound absorption. The sound then has to branch down and is lost.
  • the stone fill can consist of round grain or split.
  • the surface is intended to serve as sound absorption, particularly on and in buildings, such as bridges and tunnels, especially on slab roads, i.e. when laying the rails on concrete.
  • the surface should be able to be cleaned, especially at train stations.
  • the strength of the surface of the covering - how deep the consolidation extends can be controlled by the amount of glue sprayed on - allows cleaning, for example, by steam radiation and simultaneous suction.
  • Another advantage is the ability to break open the covering for repair purposes, for example on a threshold, and then restore it with the same stone material.
  • the topping as a rule, goes up to the upper edge of the threshold. It also protects against gravel flying.
  • a triple bed of stone is applied to a track body, depending on the conditions, of about 20 to 25 cm total thickness.
  • the lower layer consists of a quartz grain (round grain) grain size 2 to 4 mm, the middle layer of a split grain (basalt or limestone) grain size 4 to 11 mm and the upper layer of a split grain (basalt or limestone) grain size 8 to 16 mm.
  • the lower and middle layers each take about 30%, the top layer takes up about 40% of the total thickness.
  • An epoxy resin adhesive is sprayed onto it in an amount of, for example, 2 kg / m2.
  • the adhesive is a 2-component adhesive.
  • the resin component consists of non-brominated bisphenol A resins and cycloaliphatic resins.
  • a mono- and / or bifunctional reactive diluent, phosphoric acid ester as flame retardant, silicic acid ester as adhesion promoter and a silicone defoamer are added.
  • the hardener component consists of adducts of amines, amides, phenol-free Mannich bases or mixtures thereof, benzyl alcohol as an accelerator, silicic acid ester as an adhesion promoter and silicone defoamer.
  • the adhesive forms a solid layer to a depth of approximately 10 cm. Below that, the solidification becomes looser and then only in places.
  • this is sprayed with a spreading multi-component epoxy resin adhesive or multi-component polyurethane resin adhesive.
  • the spreading adhesive runs around the gravel stones and in this way always reaches the points of contact of the stones with each other, where it connects them after it has hardened, but beforehand, if necessary, on the next stone, etc. overflows downwards - always along the stone surfaces and not filling the cavities.
  • the adhesive which is spread evenly by spraying, solidifies a flat surface layer of the ballast and forms stalactites underneath. With a larger amount of glue, the stalactites form at somewhat closer distances from one another. They partially extend to the bottom of the ballast bed and form a foot here again. As the amount of glue is reduced, the spacing of the stalactites increases and their lengths become shorter. A controlled consolidation of the ballast bed can thus be achieved with the amount of adhesive used. The railway sleepers embedded in the ballast bed are then kept stronger.
  • the hold is improved even if the railway sleepers are also sprayed and thus have the same bond with the ballast bed as the ballast bed in itself.
  • the amount of adhesive to be used depends on the circumstances. It will generally be over 2 l / m2, usually between 5 and 8 l / m2.
  • the resin component consists of non-brominated bisphenol A resins and cycloaliphatic resins.
  • a mono- and / or bifunctional reactive diluent, phosphoric acid ester as flame retardant, silica ester as adhesion promoter and a silicone defoamer are added.
  • the hardener component consists of adducts of amines, amides, phenol-free Mannich bases or mixtures thereof, benzyl alcohol as an accelerator, silicic acid ester as an adhesion promoter and silicone defoamer. Instead, a multi-component polyurethane resin adhesive would also be possible.
  • the adhesive is applied, for example, in an amount of 6 to 7 kg / m2.
  • the ballast bed is more elastic than the concrete.
  • the rails sink by about 1.5 to 4 mm, mostly by about 3 mm, on concrete only by 0.5 to 1.5 mm, mostly by about 1 mm, and that through the plastic layer between concrete and rails.
  • the difference leads to a shock or impact when changing the wheels from one lane to the other.
  • the soft trackway is solidified after spraying with a spreading multi-component epoxy resin adhesive or multi-component polyurethane resin adhesive and the solidification with increasing distance from the solid roadway reduced by reducing the amount of adhesive used.
  • the consolidation is preferably carried out initially for a certain amount and then decreasing.
  • the spreading adhesive stretches around the gravel stones and in this way always reaches the points of contact of the stones with one another, where it connects them after it has hardened, but beforehand, if necessary, on the next stone, etc. overflows downwards - always along the stone surfaces and not filling the cavities.
  • the invention includes the finding that this consolidation can be controlled well with the amount of adhesive used, largely through the local distribution of the adhesive.
  • the adhesive which is spread evenly by spraying, solidifies a flat surface layer of the ballast and forms stalactites underneath. With a larger amount of glue, the stalactites form at somewhat closer distances from one another. They partially extend to the bottom of the ballast bed and form a foot here again. As the amount of glue is reduced, the spacing of the stalactites increases and their lengths become shorter.
  • the irreversible displacements of the ballast stones against each other that occur over time are reduced, which can lower the ballast bed and thus further lead to the blow at the transition from the soft to the solid road and vice versa.
  • the section of constant strength has a length of 5 to 15 m, for example, the section of decreasing strength has a length of 10 to 20 m, for example.
  • the adhesive will be used in an amount of 5 to 8 l / m2, decreasing to 1 to 2 l / m2.
  • Figure 2 shows an embodiment of the invention. It shows a vertical longitudinal section through a railroad track, an enlarged section drawn out.
  • a rail track with rails 11 on sleepers 12 runs from a natural surface 13 onto a bridge 14.
  • the sleepers 12 are mounted on a ballast bed 15 above the natural surface.
  • bridge 14 they lie directly on the concrete.
  • the ballast bed 15 is uniform by spraying an adhesive penetrating into the ballast bed on a section 16, for example 10 m long, adjoining the bridge 14 and then on a section 17 of for example, 15 m in length, solidified.
  • the decrease in hardening primarily results from a decreasing average penetration depth of the adhesive. It follows to a small extent from an increase in the distance between the locations where the adhesive extends downwards in the form of stalactites 18.
  • the adhesive is a two-component adhesive.
  • the resin component consists, for example, of non-brominated bisphenol A resins and cycloaliphatic resins.
  • a mono- and / or bifunctional reactive diluent, phosphoric acid ester as flame retardant, silica ester as adhesion promoter and a silicone defoamer are added.
  • the hardener component consists of adducts of amines, amides, phenol-free Mannich bases or mixtures thereof, benzyl alcohol as an accelerator, silicic acid ester as an adhesion promoter and silicone defoamer. Instead, a multi-component polyurethane resin adhesive would also be possible.
  • the adhesive was applied to section 16 in an amount of 6 to 7 kg / m 2 and on section 17 decreasing evenly to 1 kg / m 2.
