Definitions

  • the invention relates to the field of marble processing to produce so-called marble-chip floor tiles or marble tiles, or generally slabs of marble, granite or stone, or stone material in general.
  • marble-chip floor tiles or marble tiles or generally slabs of marble, granite or stone, or stone material in general.
  • stone material in general, including stone, granites, etc. as well as marble.
  • slabs or tiles without distinction, it being understood that the invention applies to one and the other without limitations of size.
  • fibreglass is sprayed on top of a liquid resin applied to the back of the tile.
  • the results obtained are not satisfactory and besides the working environment is made hazardous by the harmful microparticles which are dispersed into the air.
  • a further object is to make the tiles stronger over time, that is, to ensure that the tiles do not suffer structural or cosmetic changes once applied either due to the application materials or due to environmental factors.
  • a further object is to obtain the preceding objects at a cost compatible with the market.
  • the new product comprises a layer of marble coupled, by gluing on the back, to a single layer or a multilayer of kraft paper impregnated with phenolic resin.
  • a laminate known as LPR - a registered trademark of LIRI Industriale - or FORMICA - a registered trademark of the FORMICA CORPORATION - without the outer layer of melamine resin can be used as the backing.
  • a block of marble is coupled on its two larger surfaces with respective backing sheets as stated above, by means of gluing and then it is divided or separated, that is, cut in half parallel to the larger surfaces, so as to obtain two slabs, which are then cut to the desired shape and size.
  • the new tile with a backing according to the invention has numerous advantages.
  • the perfect adhesion of the backing to the marble and its characteristic of elasticity mean that, besides stability, flexibility and tensile stress are increased. Consequently there is less waste during processing and a greater yield, and in addition the covering with the tiles lasts longer and is stronger.
  • the consistency obtained makes it possible to create tiles with smaller thicknesses than those currently on the market, which allows them to be used for tiling in sectors where greater lightness is particularly necessary (tiling of ships, lifts, skyscrapers, etc.) and with a considerable saving on the raw material used.
  • the reduction in specific weight is about 10% or even more. This also results in a reduction in transport costs.
  • a further advantage is that the material can be set in place using normal glues, without having to use specific products to make it adhere walls and without the colour of the glue appearing on the visible surface of the tile.
  • a further advantage consists in the fact that, once the slab or tile has been set in place, the supporting sheet forms a barrier against damp rising from the wall to the marble, and thus the inherent problems such as stains or cracks are eliminated.
  • the new tile 10 comprises a layer of marble 11 and a backing sheet 12 glued to the layer of marble on the back thereof.
  • the backing according to the invention comprises a single layer or a multilayer of kraft paper impregnated with phenolic resins.
  • a laminated product known as LPR, or FORMICA, preferably deprived of the melamine layer, can be used.
  • a block of marble with a thickness more than double the final thickness that is to be obtained for the tiles is first cut; said block is indicated by reference numeral 20.
  • two backing sheets 21, 22 in a single layer or a multilayer of craft paper soaked in phenolic resins are applied. These backing sheets are applied by gluing.
  • the block is then left to dry.
  • the block is then divided or sawn roughly in half, or in any case in an intermediate position with respect to the thickness, along a plane p parallel to the planes of the larger faces, so as to obtain two strips 20a, 20b that each have an exposed marble surface and the backing.
  • the two strips are then processed as desired on the surface on view and cut to the desired final shape and size of the tiles.
