Definitions

  • the invention relates to a method for the production of thin natural stone slabs which are glued on a support.
  • Natural stones in the context of the present invention may in principle be all types of natural stones used for technical and decorative purposes.
  • Preferred natural stones in the context of the present invention are granite and marble.
  • Thin natural stone slabs glued to a support are already known. They are made by thicker natural stone slabs, which are glued on a support, material-consuming and costly removed with a router.
  • marble panels are known.
  • the marble slabs are fixed on bars, which are mounted on a metallic support.
  • the individual panels are connected with the help of clips.
  • A1 dimensionally stable plate-shaped composite elements are described with a core of a specific light and a specially shaped honeycomb carrier material, said core with a wear layer material, for. B. a natural or artificial stone, is covered.
  • the carrier material has tetrahedral truncated honeycombs which have circular or ellipsoidal, square or rectangular cutouts (col. 2, lines 26 to 44).
  • materials for the support material polyethylenes, polypropylenes and polystyrenes are generally called (page 3, lines 4 to 8).
  • commercially available polyurethane mounting foam was used. The anchoring to the ground is done with screws.
  • the lightweight carrier material can be made of aluminum or plastic (polystyrene or polyurethane) and is reinforced by glass fibers.
  • the lightweight carrier material can also be made of aluminum or plastic (polystyrene or polyurethane).
  • A1 plate-shaped natural stone composite elements are described, which have on the, the cover plate opposite side, a leveling layer or equalization zone.
  • the compensation layer or compensation zone should consist of a material that is easily removable in contrast to the plate material (column 2, line 65 to column 3, line 8).
  • EP 1 298 262 A1 describes the production of thin natural stone slabs. On both sides of the natural stone plate carrier plates z. B. attached with a two-component epoxy adhesive. The separation of the plate is then done with the aid of a gang saw.
  • thin-walled slabs having a thickness of less than 6.25 mm are fixed on a support for a wide commercial use, e.g. In the Building area (floors, walls or facades) are not offered, since the production methods described above for mass production are too expensive.
  • a splitting machine for natural stone in which a plurality of serially arranged diamond-covered saw blades rising saw blade diameter are arranged on a drive axle.
  • thin natural stone slabs in the range of 6.25 to 8 mm thickness can be produced with this machine.
  • the production of thinner plates is practically impossible because of the high mechanical load and the loss due to plate breakage.
  • Object of the present invention is to provide a method for producing very thin natural stone slabs.
  • Thin natural stone slabs in the context of the present invention are slabs with a thickness of the stone in the range of about 0.3 to about 6 mm.
  • Thin natural stone slabs in the context of the present invention may preferably plates having a thickness in
  • Range of 1 to 6 mm, more preferably in the range of 1, 5 to 5.5 mm, and more preferably in the range of 2 to 5 mm are produced.
  • the thicker plates to be cut generally have about twice the thickness of the thin plates to be produced according to the invention.
  • the splitting machine for natural stones for the method according to the invention is known per se.
  • the splitting machine for natural stones generally consists of successively connected saw blades (diamond-set) with increasing saw blade diameter, which are arranged in series on a drive axle. In series more than 20 saw blades can be arranged.
  • Each saw blade cuts one piece deeper into the stone. For example, in granite, the first saw blade cuts approximately 15 to 20 mm deep, the next saw blade cuts another 15 to 20 mm deep, etc.
  • the saw blades can be arranged horizontally or at an angle of inclination.
  • the water supply for cooling and slurrying the sawdust is continuously ensured by the arrangement of the saw blades.
  • a machine type which consists of two parallel, but staggered rows of saw blades.
  • Each row of saw blades consists of several consecutively arranged with diamond-covered saw blades rising blade diameter. The stone is sawn on both sides at the same time.
  • doubling of the slab width can be achieved by first cutting the stone halfway through and then turning it off from the other side in the second sawing step.
  • the achievable width of the thin stone slabs is currently technically limited by the diameter of the saw blades, which still allows a vibration-free sawing process.
  • the separation of a thicker natural stone slab with the natural stone splitting machine may be carried out centrally but also elsewhere to produce two different thicknesses of thin natural stone slabs, each on a support.
  • a carrier is glued on both sides of the thicker natural stone slab.
  • adhesives which are largely water-resistant and elastic due to the selected molecular structure are preferred. It is preferred to use adhesives based on silicone, polyurethane or epoxy (single or two-component adhesive).
  • Preferred supports may be, for example: HDF boards, MDF boards, screen printing plates,
  • polystyrene polycarbonate
  • polyester polyetherimide
  • polypropylene polyethylene
  • Polyamide carrier made of plastic honeycomb (honeycomb systems) z.
  • B polyacrylic
  • Carrier made of light metals such as aluminum or titanium. Between two metal plates can honeycomb plastic inserts z. B. from: polyacrylic, polystyrene, polyamide, polyetherimide, polyamide, aramid.
  • the supports may preferably be 0.5 mm to 100 mm, in particular preferably 7 mm to 30 mm thick.
  • a thick natural stone slab is glued on both sides with a carrier to form a sandwich.
  • the two carriers may be the same or different.
  • With the described splitting machine for natural stones becomes the natural stone is sawn through. This gives two plates consisting of natural stone each glued to a support.
  • the achievable width of the thin slabs is technically limited by the diameter of the saw blades, which still allows a vibration-free sawing process.
  • the progressive development in the field of natural stone saw blades using new alloys enables the production of thin stone slabs with a width of more than 60 cm.
  • a glass fiber or carbon fiber fabric on the underside.
  • the carriers can be coated on the top and bottom with a melamine or phenolic resin and with a carbon fiber or glass fiber.
  • FIGS. 1 and 2 The present invention may be illustrated by FIGS. 1 and 2:
  • Figure 1 shows a splitting machine for natural stones (4) with a series of saw blades, which are driven by the drive axle (5).
  • the natural stone slab (1) is glued between the supports (2 and 3).
  • Figure 2 is a splitting machine for natural stones (4) with two rows of saw blades, which are driven via the drive axle (5).
  • the natural stone slab (1) is glued between the supports (2 and 3).
  • the produced by the novel process natural stone slabs on carrier are economically extremely interesting, as in relation to the massive natural stone a significant reduction in weight is achieved, resulting in a wide range of applications, inter alia, in the fields of construction (floors, walls, ceilings, facades), furniture, kitchen panels , Aviation, Caravan, yacht or railway construction opens up.
  • support materials such as HDF, or recycled materials can be laid in the private sector floors and walls much easier with natural stones, as if heavyweight massive natural stone slabs must be laid.
  • the layman will also be able to lay the thin-stone slabs "do it your self", especially as it is possible to cut the thin slabs even with simple cutters from DIY stores Dry laying can be done without manual skills by the layman.
  • a 10 mm thick granite slab of Blue Pearl with the dimensions: 61 cm long and 30.5 cm wide is provided by means of an elastic PU adhesive with a thin glass fiber and then with the same adhesive on both sides in each case with an 8 mm thick, 61 cm long and 30.5 cm wide HOF plate stuck.
  • the carrier plates are plastic-coated on the top and bottom.
  • the granite plate is cut through in the middle.
  • This machine consists of a series of 20 consecutive saw blades rising saw blade diameter, the saw blades are all arranged at the same height.
  • the saw blades are diamond-studded.
  • the sandwich is now divided into two identical plates each consisting of a carrier plate glued with a granite layer only 3 mm thick (from the granite plate used 3 to 4 mm in the form of sawdust lost).
  • the preserved natural stone slabs are calibrated, chamfered and polished.
  • the marble slab is cut horizontally.
  • the machine consists of two parallel rows of 3 saw blades each. The respective offset opposite leaves have the same diameter. Within the rows the saw blade diameter increases.
  • the saw blades are diamond-studded.
  • the preserved natural stone slabs are calibrated, chamfered and polished.
