Definitions

  • the present invention relates to a method for manufacturing an article made of conglomerate material in the form of a slab or block using compaction technology already known in the sector of agglomerated materials.
  • this technology comprises an initial step involving preparation of a mix comprising a granulated inert material, for example granules obtained from materials such as granite, quartz, feldspar, marble, glass or ceramic materials.
  • a filler and a hardening binder, such as a resin or a hydraulic cement, are then added to the granulated material.
  • the mix is then distributed inside a mould and subjected to a compacting action which is often performed under a vacuum.
  • the mould which contains the compacted article is transferred to a station where the binder is hardened so as to obtain in this way a solid and firm article.
  • Said hardening station will vary depending on the type of binder used.
  • the article is in the form of a block, it is then sawn into slabs; the slabs are normally surface- finished.
  • decorative elements which may be simple elements such as glass or mirror fragments or metal elements such as brass or the like, are added to the granulated material to form the mix.
  • Conglomerate articles are made so as to incorporate inside them reflective, coloured, decorative glass elements commonly known as "aventurine" which enrich the product and make it particularly attractive and pleasing and suitable for environments such as those indicated above.
  • EP 0,521,286 it is also proposed inserting transparent granules with a mirror-like metallized surface and performing a subsequent slab smoothing operation.
  • the exposed granules thus reflect the light internally.
  • the main object of the invention is to provide a conglomerate article which is particularly attractive from an aesthetic point of view and which has a reasonable cost such that it may be suitable for widespread distribution and use.
  • granules of transparent material lined with a coating comprising glitter are added to the mix and, after the hardening step, a material removal operation is performed so as to obtain a surface of the article which is intended to remain visible and on which at least a few granules are exposed with their glitter-free surface.
  • the surface of the slab intended to remain visible undergoes a subsequent processing step, which may consist in sizing and smoothing, so that the coating of the portion of said granules embedded below the visible surface of the conglomerate article creates a reflective effect on the visible surface.
  • the invention also relates to a conglomerate stone article which can be obtained from a mix comprising a natural and/or synthetic granulated stone material, a thin filler and a hardening binder, said mix being distributed inside a mould, compacted and then hardened, characterized in that it comprises granules of transparent material partially incorporated within the article and having part of their surface exposed on a surface of the article and having a coating comprising glitter on their incorporated part.
  • the invention also relates to the granules of transparent hard material which are lined with a coating consisting of glitter.
  • Glitter is a special product in the form of very small reflective and shiny flakes/grains which is well known and widely used in sectors such as the painting, cosmetic and clothing sector in order to obtain an aesthetic and/ or decorative effect.
  • FIG. 1 shows partial schematic and cross-sectional view of an article, during an intermediate processing step, obtained according to the invention
  • FIG. 2 shows a view, on a larger scale, of the article according to Figure 1 after a further processing step with mechanical removal of material from the surface, for example a smoothing and subsequent polishing operation.
  • the article of conglomerate material is obtained by means of the method, the various steps of which are described hereinbelow.
  • the first step envisages the preparation of a mix consisting of:
  • granulated natural stone material such as marble, granite, quartz, silica sand or artificial stone materials such as ceramic or glass materials;
  • an organic binder such as polyester, epoxy, acrylic or biolenic resin or an inorganic binder such as Portland cement;
  • a thin powder filler consisting for example of siliceous or calcareous material
  • additives are added in order to favour the hardening reaction of the binder and other pigmented additives
  • the glitter may be applied to the granules of hard material using various techniques which can be easily imagined by the person skilled in the art.
  • the glitter used may have a particle size of between 0.1 and 2.0 mm.
  • the quantity of granules is such that the percentage by volume, relative to the total volume of the resin and the granules themselves, is between 40% and 60% and is preferably equal to 50%.
  • the particle size of the granules of inert material is between 0.1 mm and 8 mm and preferably between 0.5 mm and 5 mm.
  • the quantity of granules of transparent hard material lined with a coating consisting of glitter depends on the desired aesthetic effect; it may for example constitute a portion equal to 1- 20% of the mix.
  • the mix is rendered homogeneous by means of a mixing operation which is performed inside special mixers. Then the mix thus prepared is distributed inside a mould.
  • hardening of the binder is performed, so as to incorporate in a permanent manner the granules of inert material.
  • Hardening may be performed in hot or cold conditions, or at room temperature, depending on the type of binder.
  • the hardened article is a block, it is sawn into slabs.
  • Figure 1 shows on a larger scale, a surface zone of an article, generally denoted by 10, following hardening, with inside granules 11 lined with a layer of glitter 12 (the granules 11 in Figures 1 and 2 are schematically shown with a spherical shape, but in reality normally they have an irregular and jagged form).
  • a transparent adhesive 13, if used, may be present as an intermediate layer.
  • Figure 2 shows the zone of the article after the following processing step which envisages a mechanical operation with removal of material from the surface in order to expose the granules and form transparent "windows" 14 on their surface which is exposed on the visible side 15 of the article.
  • This mechanical material-removal operation may coincide with a sizing and smoothing step carried out on the slabs.
  • each exposed granule which remains embedded underneath the visible surface reflects the light since the glitter on its surface reflects the incident light which passes through the granule, producing an aesthetic effect which is particularly pleasing and attractive.
  • the operation of mechanical removal of material or smoothing of the surface of the article intended to remain visible may be more or less deep depending on the desired optical effect.
  • smoothing as shown in Figure 2, removes at least a superficial part of the granule until a flat surface, which allows entry and emission of the reflected light and which is perfectly coplanar with the remaining surface of the article, is obtained.
  • the glitter-lined granules must be made of material which is sufficiently hard (for example, having a hardness substantially comparable to the hardness of the remainder of the article) and sufficiently transparent.
  • the article may be bonded with resins and therefore undergo catalysis at temperatures which may be as high as 140°C; therefore, the glitter-lined granules must withstand a temperature of at least 160°C and moreover must not be prone to attack by organic solvents such as styrene, contained in the resin used.
  • the granules to be lined with glitter may, for example, be made of transparent quartz or glass.
  • the particle size of the granules, in the same way as the particle size of the granulated material used, is preferably between 0.1 and 8 mm.
  • the colour of the coating composed of glitter may vary.
  • the glitter used may be gold or silver coloured so as to obtain gold or silver-lined granules such that the finished product may be even more attractive for customers.
  • the granules may also be made of semi-transparent material so that, with their coloured mass, they provide colouring for the light which passes through them and is reflected by the glitter.
  • the granules may have an irregular or more or less regular geometrical shape.
  • glitter provides, among other things, an irregular reflective surface which multiplies the light rays reflected towards the outside of the surface of the article and reflects them in random directions. This enables a very effective and aesthetically innovative and pleasing light effect to be obtained, compared, for example to the formation of a simple continuous and/ or uniform mirror coating on the surface of the granules.
  • the operation involving mechanical removal of material may be performed to a smaller depth, such that it may consist of only a simple brushing operation in the case where the binder is particular soft and/or the surface granules project from the surface after hardening of the mix (for example, following no or only limited pressing of the mix).
