Definitions

  • the present invention relates to a method for increasing the anti-skid, respectively. the sliding friction on an enamel coated surface, with a method according to the preamble of claim 1, with an arrangement with increased anti-slip or increased sliding friction on an enamelled surface, with an application of the method and with a bath or shower tray with an arrangement according to the invention .
  • Adhesive anti-skid patterns such as stripes, dots or decals, are known, for example, which are glued to the enamel cover of the bathtub or shower tray.
  • the problem with these glued anti-slip patterns is, on the one hand, that they come off after a short time and that they appear very dirty, especially after a short time. It is also not surprising that this anti-skid device should be considered hygienically questionable.
  • Rubber mats or self-adhesive sliding mats are also available, which can be placed in the bathtub or shower tray. These mats are, in turn, very hygienically questionable and show fungal attack after a short time.
  • DE-OS 34 05 768 proposes coating both sides of a sheet with enamel layers, the two enamel layers being mixed with different amounts and compositions of mineral fillers so as to have different properties.
  • the proposed enamel layers are not suitable for the non-slip formation of bathtub surfaces.
  • this object is achieved by means of a method. an arrangement according to the wording according to claim 1 or Claim 5 solved.
  • a method for hearing the anti-skid or resp. the sliding friction on a surface coated with at least one base enamel and one cover enamel characterized in that a finely ground mineral-based powder is applied at least in some areas of the surface before the cover enamel coating is baked, and this is then baked together with the cover enamel coating.
  • top enamel layer which should still be at least partially in a flowable state, a finely ground quartz-based powder is applied at least in parts of the surface, and the quartz powder is then baked together with the top enamel.
  • the grain size of the quartz powder used should be ⁇ 0.3 mm, preferably 0.12-0.16 mm and for the production of the powder preferably annealed, cleaned quartz should be used, which is broken to produce the powder by means of a so-called vibrating mill.
  • the use of the so-called vibratory mill has the advantage that the quartz powder has relatively strongly rounded edges, i.e. is not sharp-edged. This has the advantage that in areas where the quartz powder is applied, this increases the sliding friction, for example in a shower or bathtub, but there is no risk of injury due to abrasion of the skin for a person standing in the shower or bathtub .
  • the bulk density when applying the quartz powder is according to the invention in a range of 0.05-2.0 g / dm2 or. preferably in a range of 0.5-0.8 g / dm2.
  • the quartz powder can be arranged regularly over the entire surface or evenly distributed according to a predetermined pattern in partial areas in the cover enamel.
  • such a pattern has circular disks with a diameter of 2-3 cm, and the circular disks are spaced apart from one another at intervals of 1.5-3 cm. Based on the dimensions given above, there are approx. 6-8 circular disks coated with quartz powder in an area of 10 by 10 cm. It is less important that the specified dimensions are strictly adhered to than that the arrangement gives a foot, whether small or large, the necessary slip resistance.
  • the layer thickness of the cover enamel can be, for example, approximately 80 ⁇ m.
  • the above-mentioned methods according to the invention are particularly suitable for arranging an anti-skid device in a bath or shower tray, which also applies correspondingly to the above-mentioned arrangements according to the invention.
  • An anti-skid device according to the invention is shown schematically in cross section in FIG. 1.
  • a base layer or base enamel layer 3 is initially arranged, the primary task of which is to compensate for unevenness in the tub surface and also to guarantee good adhesion of the cover enamel.
  • a cover enamel 5 is applied to this base layer 3, which in some areas comprises the anti-slip protection, which consists of finely powdered quartz grains 7. It is possible to arrange the quartz powder 7 uniformly over the entire surface, or in parts as in FIG Fig. 1 shown.
  • the advantage of arranging in partial areas is that significantly less quartz powder has to be used to achieve practically the same anti-slip protection, since there is practically no anti-slip protection below a certain bulk density. The result of this is that, with the same amount of powder used, a substantially reduced anti-slip protection is obtained over the entire surface than if the same amount of quartz powder is applied more concentrated in local partial areas, as is shown in FIG. 1.
  • FIG. 2 shows the arrangement according to FIG. 1 in a top view, as a result of which only the cover enamel 5 and the quartz powder pattern 7 are visible, while the surface 1 underneath disappears under the cover layer 5.
  • Fig. 3 is now shown schematically how the anti-skid according to the invention, as shown in Figs. 1 and 2, applied or. is arranged.
  • a base layer 3 is arranged over a surface 1, which in turn is coated by the cover enamel 5.
  • a frame 13 is arranged on supports 15, in which cup-shaped structures 11 according to the pattern of FIG. 2 are embedded. These cups 11 are circular, funnel-shaped and are open at their upper and lower ends.
  • a transport device 17 On which a funnel-shaped storage container 19 is movably arranged and can be moved both in the longitudinal direction (according to the arrow shown) and in the transverse direction.
  • the quartz powder 23 is now arranged in this funnel-shaped storage container 19 and passes through an opening 21 can be drained downwards in the storage container.
  • the storage container 19 is now moved over the funnels 11, with the powder in the area of the funnels 11 passing through these onto the still flowable or. wet top enamel layer 5 arrives.
  • the circular patterns as are shown, for example, in FIG. 2, or other arbitrary patterns are created.
  • the supports 15 with the funnels and the storage container are removed from the surface 1, and the cover enamel layer 5 is dried together with the sprinkled powder and then baked. Stoving is a known stoving or enamelling technique, which will not be discussed further here.
  • FIG. 4 and 5 the arrangement of an anti-skid device in a bathtub is shown schematically.
  • 4 shows the process in the longitudinal cross section of the bathtub and
  • FIG. 5 shows the process in a top view.
  • a bathtub 31 has an inner surface 33 which is coated, for example, with the cover enamel which is still wet.
  • the anti-skid device is preferably arranged in the leg area 33a, i.e. near an outflow opening 32, since the provision of an anti-skid device in the seating area of the bathtub is not desired.
  • a frame 35 Arranged in this leg region 33a of the bathtub 31 is a frame 35 which has the cup-shaped openings 37 on its underside.
  • the frame 35 is supported on the bathtub floor 33 by means of supports 39.
  • the quartz powder is again entered by means of a storage cup or.
  • Dosers 41 which on its underside can have a reclosable opening 43 through which the powder is dispensed when the anti-skid device is produced.
  • the metering device 41 is slidably mounted in the longitudinal and transverse directions on an arm 45 with joints 47 on a stand 49 which moves or moves via a control and drive unit 51. is driven.
  • the drive resp. Control unit 51 is of course only shown schematically, since it is not actually part of the invention.
  • the frame 35 is now arranged over the supports 39 in the leg area 33a of the bathtub 31, this being able to take place automatically, for example, along a production line. It is essential that the cover enamel is still wet on the inner surface of the bathtub. is flowable so as to enable the quartz-like powder to be at least partially immersed in the cover enamel.
  • the advantage of using quartz powder is that the coefficient of expansion of quartz is very small and can be optimally melted into the structure of the cover enamel, as is usually used for coating bathtubs.
  • the quartz powder in the metering device 41 is now evenly distributed over the pattern-like openings 37 in the lower part of the frame 35, this being done by means of the control 51, the stand 49 via the arms 45 and by means of the joints 47. It is of course possible that the process is computer-controlled, ie that in the drive or. the control 51 has a programmed input so that the quartz powder is dispensed evenly and only through the openings 37 of the frame 35.
  • An advantageous dosage of the quartz powder when dispensing was found to be a bulk density of 0.65 g / dm2.
  • the bulk density depends strongly on the layer thickness of the enamel and on the grain size of the quartz powder and is preferably in a range of 0.5-0.8 g / dm2.
  • the frame 35 is removed again from the bathtub and the cover enamel is dried and baked together with the quartz powder deposits.
  • the main advantage of producing this anti-skid device is that no additional burn-in resp. Work process is required when manufacturing the bathtubs. It is also advantageous that the anti-slip protection obtained in this way is also optimal when only small amounts of water are still present at the bottom of the bathtub and have a soapy character.
  • Another advantage of this anti-skid device is that the application of the quartz powder is color-independent, i.e. the burned-in quartz powder does not affect the color of the cover enamel. Quartz can also be baked in any color.
  • anti-slip layers produced according to the invention were tested for chemical resistance.
  • an inventive sliding layer for 24 hours and 80 ° C with a 5% sodium hydroxide solution was covered, for example, with subsequently could be identified no visible changes.
  • Figs. 1-5 for example Orders or Procedural instructions of an anti-skid resp. to produce an anti-skid device according to the invention can be modified and modified in any desired manner.
  • any desired means can also be used instead of cups to distribute the quartz powder on the enamel layer.
  • a perforated sieve it should also be said that, for example, they are preferably transparent, although the entire bottom section of the frame 35 can of course be transparent.
  • the method according to the invention is suitable for any enamel method, such as, in addition to the method described above, also for the so-called “two coat, one fire” method. It is essential that a quartz-like powder is applied in a cover enamel layer, the quartz powder being baked together with the cover enamel.
