Definitions

  • the present invention relates to a synthetic mat, in particular a synthetic grass mat, and a process for the production thereof, of the type specified in the preamble of the independent claims.
  • synthetic grass mats are produced to replace expanses of natural grass on playing fields, parks and the like.
  • These are commonly composed of elements, at least partly bladelike, made of polymer material which simulate, for example, blades of grass, secured to a backing preferably realized by a synthetic fabric with appropriate strength.
  • Securing of the at least partly bladelike elements to the underlying backing preferably takes place by means of a further layer of adhesive, generally made of rubber latex, which is spread on the opposite face to the exposed surface of the mat.
  • Synthetic mats in particular synthetic grass mats for playing fields, are subjected to considerable wear and periodically restored through replacement.
  • said adhesive is preferably oven dried: this causes considerable energy consumption and potentially polluting atmospheric emissions.
  • the technical aim underlying the present invention is to devise a synthetic mat capable of substantially overcoming the aforesaid drawbacks.
  • Another important aim of the invention is to produce a simple and inexpensive synthetic mat.
  • the synthetic mat according to the invention is indicated as a whole with the number 1 .
  • a surface 1a preferably flat when installed, and comprises, parallel to the surface 1a, an outer face 1b , suitable to realize the walking or outer surface of the mat 1, and an inner face 1c , suitable to face the ground or other backings when installed.
  • the synthetic mat 1 comprises, briefly, a plurality of bladelike elements 2 , a backing membrane or sheet 3 for these bladelike elements 2 and, preferably, a membrane or sheet 4 for joining the bladelike elements 2 to the backing membrane 3.
  • the bladelike elements 2 pass through at least a pair of holes 5 , provided or resulting from the weaving operation, present in the backing membrane 3.
  • the bladelike elements 2 take place according to prior art mat weaving techniques.
  • the bladelike elements 2 are bladelike elements or groups of continuous bladelike elements each inserted in a series of holes 5, producing a plurality of reciprocally connected slot-like surface elements.
  • the upper ends of the slots can be cut to produce a plurality of bladelike surface ends 2a for improved simulation of the pile, of the blades of grass and the like.
  • Said arrangement causes bladelike surface ends 2a to be produced on each bladelike element 2, which exit from the backing membrane 3 on the outer face 1b and connection portions 2b of each bladelike element 2 which exit from the backing membrane 3 on the opposite face to the bladelike surface ends 2a.
  • the bladelike elements 2 are heat-sealed to the backing membrane 3, preferably along the connection portion 2b thereof disposed on the opposite face of the backing membrane 3 with respect to the bladelike surface ends 2a.
  • the joining membrane 4 is disposed parallel to the backing membrane 3 and to the surface 1a, and is also heat-sealed to this backing membrane 3, on the side of the inner face 1c of the synthetic mat 1.
  • the bladelike elements 2, the backing membrane 3 and the joining membrane 4 are made of a thermoplastic polymer matrix material.
  • the term polymer is also intended as thermoplastic rubbers.
  • Said elements can therefore be made of thermoplastic polymer materials or of composite materials having a thermoplastic polymer matrix and charges, powders or fibres of different materials. Said charges or fibres are appropriately present in quantities that do not affect the recyclability of the materials.
  • the bladelike elements 2, the backing membrane 3 and the joining membrane 4 are made of reciprocally heat-sealable polymer matrix materials, more preferably said matrices are made of polymers belonging to the same family of polymers and even more preferably said matrices are made of the same polymer.
  • polyethylenes and polypropylenes are preferably used due to their chemical resistance and to their low environmental impact.
  • the bladelike elements 2 have a height that varies according to use, in particular for football fields the length of the bladelike surface ends 2a is preferably between 1 cm and 5 cm.
  • the backing membrane 3 is preferable made of polymer matrix material charged with powders, fibres or glass fabrics or meshes or the like.
  • the thickness of the membrane is variable and preferably between 0.2 cm and 3 cm.
  • the joining membrane 4 is instead suitable to give consistency to the mat 1 and to block the bladelike elements 2 with greater efficacy. It also has a thickness preferably between 0.2 and 3 cm and is preferably made of polymer matrix material charged with powders, fibres or glass fabrics or meshes or the like.
  • the structure can also be provided with parts made of foamed polymer to modify the physical properties thereof as required.
  • the invention comprises a new process 10 for the production of a synthetic mat 1, and in particular of a synthetic mat 1 as described above.
  • This production step 11 preferably takes place using technologies for processing polymer materials of known type, such as: flat head extrusion, calendering, thermo-coating.
  • This step can also include the production of holes 5 by means of specific punches with established pitch.
  • the process 10 also comprises a step 12 to weave the bladelike elements 2 on the backing membrane 3 according to the arrangement previously described and illustrated.
  • Said weaving step 12 takes place by means of needle machines of known type, and on backing membranes 3, which insert the bladelike elements 2 into the backing membrane 3 producing holes 5, or insert them into holes 5 already present on the backing membrane 3.
  • this sealing is a heat-sealing that takes place along the portion of the bladelike elements 2 disposed on the face of the membrane 3 positioned against the inner face 1c of the mat 1. More in particular, it includes heat-sealing of the connection portion 2b of the bladelike element 2 to the backing membrane 3.
  • Said heat-sealing is appropriately obtained through at least partial melting both of part of the bladelike elements 2 and of the backing membrane 3.
  • the process 10 also preferably comprises a step 14 to apply the joining membrane 4.
  • Said application step 14 can combine in a single pass the steps of producing the joining membrane 4 and of joining it through heat-sealing to the backing membrane 3 including the heat-sealed bladelike elements 2.
  • said application step preferably takes place through direct thermal coating, in particular by extrusion of a layer of polymer material in molten state onto the backing membrane 3.
  • the joining membrane 4 is produced separately and subsequently heat-sealed by means of sources of heat prevalently with surface effect, similar to those described previously.
  • the invention achieves important advantages.
  • the mat 1 is structured in an manner suitable to be produced entirely by means of thermoplastic polymers. It is therefore economically and totally recyclable, also with regard to processing off-cuts.
  • said mat 1 has no adhesive dried in ovens, which causes considerable energy consumption and polluting atmospheric emissions.
  • the mat 1 is very simple and inexpensive. It can also be adapted to surfaces of different shapes, as being produced in thermoplastic material it is thermally deformable.
  • the invention is susceptible to variants falling within the inventive concept. All details can be replaced by equivalent elements, the shapes and dimensions can be any.
