Description
- 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.
- There are currently known different types of synthetic mats and in particular synthetic grass mats.
- In particular, 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.
- The aforesaid prior art presents some important drawbacks.
- In fact, prior art synthetic mats are difficult to dispose of after their replacement. This difficulty is above all due to the presence of components of different kinds which are not recyclable.
- Moreover, said adhesive is preferably oven dried: this causes considerable energy consumption and potentially polluting atmospheric emissions.
- Said difficulty in disposal is present in all facilities with synthetic mats, and consequently their replacement translates into an increase in the handling costs of this synthetic mat.
- In this situation, the technical aim underlying the present invention is to devise a synthetic mat capable of substantially overcoming the aforesaid drawbacks.
- Within said technical aim, it is an important object of the invention to obtain a synthetic mat that is easily recyclable in the same processing or easily disposed of.
- Another important aim of the invention is to produce a simple and inexpensive synthetic mat.
- The technical aim and the objects specified are achieved by a synthetic mat and by a process for the production thereof as claimed in the appended independent claims.
- Preferred embodiments are described in the subclaims.
- Further characteristics and advantages of the invention are better explained below by the detailed description of a preferred embodiment of the invention, with reference to the accompanying drawings, wherein:
-
Fig. 1 schematically shows a synthetic mat according to the invention; and -
Fig. 2 schematizes the process for the production of the synthetic mat according to the invention. - With reference to the aforesaid Figures, the synthetic mat according to the invention is indicated as a whole with the number 1.
- It extends prevalently along a
surface 1a, preferably flat when installed, and comprises, parallel to thesurface 1a, anouter face 1b, suitable to realize the walking or outer surface of the mat 1, and aninner 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 orsheet 3 for thesebladelike elements 2 and, preferably, a membrane orsheet 4 for joining thebladelike elements 2 to thebacking membrane 3. - In particular, the
bladelike elements 2 pass through at least a pair ofholes 5, provided or resulting from the weaving operation, present in thebacking membrane 3. - The arrangement of the
bladelike elements 2 takes place according to prior art mat weaving techniques. According to this technique, thebladelike elements 2 are bladelike elements or groups of continuous bladelike elements each inserted in a series ofholes 5, producing a plurality of reciprocally connected slot-like surface elements. Finally, the upper ends of the slots can be cut to produce a plurality ofbladelike 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 eachbladelike element 2, which exit from thebacking membrane 3 on theouter face 1b andconnection portions 2b of eachbladelike element 2 which exit from thebacking membrane 3 on the opposite face to thebladelike surface ends 2a. - Moreover, the
bladelike elements 2 are heat-sealed to thebacking membrane 3, preferably along theconnection portion 2b thereof disposed on the opposite face of thebacking membrane 3 with respect to thebladelike surface ends 2a. - The joining
membrane 4 is disposed parallel to thebacking membrane 3 and to thesurface 1a, and is also heat-sealed to thisbacking membrane 3, on the side of theinner face 1c of the synthetic mat 1. - The
bladelike elements 2, thebacking membrane 3 and the joiningmembrane 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.
- Moreover, the
bladelike elements 2, thebacking membrane 3 and the joiningmembrane 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. - In particular, polyethylenes and polypropylenes are preferably used due to their chemical resistance and to their low environmental impact.
- Individually, the
bladelike elements 2 have a height that varies according to use, in particular for football fields the length of thebladelike 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 thebladelike 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. - It includes a
step 11 to produce thebacking membrane 3, described. - 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 astep 12 to weave thebladelike elements 2 on thebacking 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 onbacking membranes 3, which insert thebladelike elements 2 into thebacking membrane 3 producingholes 5, or insert them intoholes 5 already present on thebacking membrane 3. - This is followed by a
step 13 to seal thebladelike elements 2 to thebacking membrane 3. - In particular, this sealing is a heat-sealing that takes place along the portion of the
bladelike elements 2 disposed on the face of themembrane 3 positioned against theinner face 1c of the mat 1. More in particular, it includes heat-sealing of theconnection portion 2b of thebladelike element 2 to thebacking membrane 3. - Said heat-sealing is appropriately obtained through at least partial melting both of part of the
bladelike elements 2 and of thebacking membrane 3. - In this sealing
step 13 it is important to avoid deformation, through excessive heating, of thebladelike surface ends 2a of thebladelike elements 2 and of thebacking membrane 3. - It is therefore appropriate to produce the heat required for heat-sealing by means of sources of heat prevalently with surface effect, i.e. acting only on the surface. These sources of heat are, for example, realized by bars with recirculating hot air, gas plates, singeing with infrared sources, directed laser beams.
- It is also appropriate to maintain the face of the
membrane 3 positioned against theouter face 1 b of the mat 1 and thebladelike surface ends 2a of thebladelike elements 2 cool. This cooling can take place by insufflating cold air on this surface, by feeding it over perforated tables or cylinders, or the like. - The
process 10 also preferably comprises astep 14 to apply the joiningmembrane 4. - Said
application step 14 can combine in a single pass the steps of producing the joiningmembrane 4 and of joining it through heat-sealing to thebacking membrane 3 including the heat-sealedbladelike elements 2. - In this case, 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. - Alternatively, 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.
- In fact, 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.
- In fact, it is unnecessary to disassemble it into different parts, in particular to separate the
bladelike elements 2 from themembranes - The handling costs of this mat are therefore greatly reduced and the environmental impact is very low or substantially non-existent.
- In particular, said mat 1 has no adhesive dried in ovens, which causes considerable energy consumption and polluting atmospheric emissions.
- These advantages are particularly important if mats 1 for playing fields, and in particular for football fields, are considered. In fact, these mats are subject to considerable wear and require to be replaced frequently.
- Moreover, 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.
