Definitions

  • the invention relates to a two-component spraying device for marking roads according to the preamble of the first claim (see EP-A-0 165 906).
  • Spraying devices of this type are used in particular for the application of center and edge lines on roads but also for marking lines in parking lots.
  • two-component colors are increasingly used in road marking because they are more resistant to wear and tear than previous road markings.
  • Two-component paints are also less prone to aging and are resistant to chemicals.
  • the glass beads strewn in the street marking to improve night vision adhere much better in a two-component paint than in conventional solvent-based one-component paints. Since the two-component paints can also be processed without solvents, they are harmless from an ecological point of view. In many countries, such as Norway, Austria and Sweden, the use of solvent-based paints is prohibited.
  • this substance is not suitable for premixing very quickly reacting two-component paints because the static mixer is quickly clogged. Even when work is interrupted, it must be flushed through with solvent immediately in order to avoid internal hardening, which is undesirable for ecological reasons.
  • US-A-4 263 346 describes an embodiment for the building industry for the simultaneous spraying of cement and reinforcing material, in which the two components are only mixed to a small extent and in no way form a chemical compound. This procedure is therefore therefore not suitable for use as a spraying device for two-component road marking, because the components here are of a completely different nature, have very different tasks to perform and do not react chemically with one another.
  • the object of the invention is therefore to provide a two-component spraying device for marking roads which does not have the disadvantages of the above-mentioned embodiments.
  • the device to be created should be simple and work without problems when using fast-drying two-component paints, it should be possible to use conventional machines.
  • the device should also be quick to assemble in a few simple steps and be quickly disassembled for cleaning the nozzle of the spray gun, for example by means of a removable bracket.
  • DUOFLEX is particularly suitable as a two-component paint, but this can only be applied by a trained specialist using a suitable spray device in order to achieve the result achieved.
  • DUOFLEX is based on a reactive polymer that dries chemically exothermically by adding a hardness component.
  • the marking can also be produced at very low cost and without significant environmental pollution.
  • Fig. 1 shows a conventional spray gun 1, which is inserted below in a holder 2 and held by means of a spring clip 3, which is also shown in FIGS. 2 and 4.
  • a nozzle device 4 both for the plastic to be applied and for the beads with hardener, or the hardener mixture or the hardener component.
  • a nozzle 5 (FIG. 3) for the outlet of the two-component paint, which extends across the marking strip, the width of which is delimited by two boundary plates 6.
  • Around the nozzle 5 there is an outlet 7 for the hardener component, which may be separate or made of beads coated with hardener.
  • the beads are supplied via a tube 8, which is spaced at an adjustable distance from a base 9, so that the flow rate of the beads can be regulated with hardener.
  • the material falls through a pipe 10 to the floor 9 and is then compressed by a connection 11 is blown through the channels 12, 13 and 14 to the outlet device 4, where it flows around it and is mixed with the two-component plastic. A chemical reaction takes place between the plastic and the pearls with hardener.
  • the conventional spray gun 1 is fastened to the feed device 15 for the beads by means of screws 16.
  • the latter is provided with a limiting device 17 which e.g. takes effect by moving the tube 8 towards or away from the plate 9 or by providing the tube 8 with a cross-section limiter.
  • the spring clip 3 consists of a clip 18, on the two arms of which a spring 19 is fastened, which is provided at the bottom with a hook 20, which engages in a hole 21 in the holder 2. To clean the nozzle 4, the bracket 18 is lifted and, if necessary, the springs 19 are removed from the holes 21, so that the spray gun 1 can be removed. Cleaning is therefore possible in a few minutes.
  • the spring clip 3 is provided at the top with a cap 22 which rests in a form-fitting manner on the head part 23 of the spray gun 1.
  • the flow through the compressed air connection 11 takes place through a hose 24, the flow quantity of which can be adjusted by means of a valve 25.
  • the air is supplied to the valve 25 through a hose 26, which is connected to a hose connection 27 at a connection 31 on the spray gun 1 and to a compressor connection 28.
  • the second connection 30 is provided for the two-component paint and the third connection 29 for the control of the gun 1.
  • the spraying process is controlled via the spray gun 1, when it is actuated, air also flows through the hose 24 to the channel 12, so that the pearls and hardener are supplied takes place simultaneously with the supply of the two-component plastic. This prevents the one-sided supply of pearls with hardener or plastic and the associated environmental pollution.
  • the metering is carried out in a metering chamber 32 and swirling in a swirl chamber 33, in which the paint is added.
  • the beads, or glass beads can be mixed with hardener, both in the form of balls or beads of approximately the same size. If these balls or pearls are roughly the same size and weight, very good mixing is achieved. Furthermore, as already mentioned, glass beads coated with hardener can also be used.
  • the hardener mixture can consist of cristobalite or quartz sand and contain an accelerator in powder form, which significantly accelerates the hardening time of the sprayed paint.
