Description

MULTILAYER MATERIAL
Field of the invention
The present invention relates to a multilayer material including a fabric and suitable for a plurality of uses. Known art
As known, materials which incorporate a fabric appropriately treated to obtain the most suitable features for a given use are currently known and employed in many fields. For example, fabrics appropriately treated with polymeric materials to obtain the required features of mechanical strength and waterproofing are commonly used to make covering sheets.
Another example widely known consists, for example, of oilskin tablecloths and shower curtains for domestic use, covering sheets for cars, motorcycles and boats, large covering cloth used in tensile structures and generally in all the applications similar to those mentioned herein, in which the features of a simple non-treated fabric, both in terms of mechanical strength to efforts and wear and, for example, in terms of waterproofing and dustprpofing, would be insufficient for the purpose, thus making the non-treated fabric itself either unusable or usable with extremely poor results.
Therefore, fabrics which are treated with a layer of reinforcement material are currently known. These fabrics may consist of fibers either woven into a fabric, or into a non-woven fabric, or knitted, and the fibers may be natural fibers such as, for example, cotton fibers or synthetic material fibers. The type of fabric, meaning both the nature of the material and the type of weave of the fibers, is chosen on the basis of the final use of the treated fabric.
With regards to the reinforcement layer, it may consist, for example, of epoxy resins, silicones, glues, paints, epoxy glues and adhesives, polymeric materials such as polyvinylchloride (PVC). Therefore, in general, they are plastic, thermoplastic or thermosetting materials, but such a material may be also a rubber, if required. All of these materials, precisely for the plastic behaviour thereof, are highly suitable to be machined by means of appropriate technological processes so as to be spread on the fabric required to be treated.
There is a plurality of currently known technological processes which may be employed to obtain the deposition and the perfect adhesion of the layer of plastic material or rubber on the surface of the fabric to be treated.
According to the reinforcement material required to be spread and adhered to the fabric, there are known processes such as calendering, thermoforming, moulding, coating processes and the more common spreading processes by means of counter-rotating cylinders which actually carry out a lamination of the material to be spread, immersion spreading, blade-on-cylinder and air blade spreading and similar processes known to the person skilled in the art.
Also in this case, the technological process depends on the reinforcement material required to be spread onto the fabric and to the desired features of the finished product. It is indeed known that the same reinforcement material may confer different mechanical features to the finished product upon varying the amount of spread material, i.e. according to the thickness of the layer of plastic reinforcement material.
It is apparent that although the materials so far described, which may be generically indicated with the term 'coated fabrics', are suitable for a wide variety of uses, they however display many drawbacks which limit the use thereof.
A first drawback consists in the fact that in order to increase the strength of a coated fabric it is necessary to increase the amount of spread plastic material, e.g. PVC, thus increasing the thickness of the reinforcement layer. In this manner, however, the coated fabric becomes rigid, with the hardened plastic material no longer being flexible.
Therefore, for the coated fabrics of the known type, the reinforcement layer of plastic material applied by spreading must necessarily remain a very thin layer in order not to loose the possibility of rolling up or folding the fabric itself at will. In the example of application of a coated fabric for making a covering sheet for a tensile structure, for example, it is apparent how it is convenient to be able to fold or roll up the covering sheet after disassembling the structure itself, and thus the waterproofing and strength of the covering sheet cannot be obtained by means of an excessively thick layer of spread plastic material.
Another drawback left unsolved by the currently known plastic material coated fabrics consists in that such fabrics are not able to keep a shape. This drawback is a direct consequence of the above, because the coated fabric usually includes a very thin layer of plastic material, adapted to stiffen and waterproof the fabric but not able to stiffen it to allow it to keep a given shape.
In this case, increasing the thickness of the plastic material layer, as mentioned, would solely lead to turn the coated fabric into a stiff board which is impossible to deform.
A further drawback consists in that the coated fabrics of the known type offer little sunray protection. Specifically, the large covering clothes let the radiation associated to natural light filter through, thus performing a negligible or totally non-existent thermal shielding effect. Summary of the invention
It is the main object of the present invention to provide a multilayer material including a fabric able to solve the drawbacks left unsolved by the materials and by the coated fabrics of the known type.
Within the scope of this object, it is a further object of the present invention to provide a multilayer material suitable to be employed in a plurality of applications in which traditional coated materials cannot be employed.
A further object of the present invention is to provide a multilayer material suitable to be employed in all the situations in which a particular mechanical strength of the material is required, not only tensile but also shearing strength. A yet further object of the present invention is to provide a multilayer material which is deformable and at the same time able to firmly maintain a given shape.
A not least object of the present invention is to provide a multilayer material which reflects the UVA radiations contained in natural light, thus providing a shielding effect, also against thermal and magnetic radiation.
These and other objects which will be better explained below are achieved by a multilayer material characterized in that it includes at least one layer of fabric, at least one layer of plastic material or rubber, and at least one layer of metal material.
Brief description of the drawings
Further features and advantages of the present invention will be more apparent from the following detailed description, provided by way of non-limitative example and shown in the accompanying drawings, in which: figure 1 shows a perspective view of the multilayer material according to the present invention in which the various layers are shown in an exploded view; figure 2 shows a section view of a first embodiment of the multilayer material according to the present invention; figure 3 shows a second embodiment of the multilayer material according to the present invention. Detailed description of the invention
According to a first preferred embodiment of the present invention shown in the mentioned figures by way of non-limiting example, the multilayer material 1 includes at least one first layer of fabric 2, on which a second layer of plastic material 3 is adhered.
This second layer of plastic material 3 may consist of polymeric materials, resins, epoxy glues and adhesives, silicones, epoxy resins and the term 'plastic material' must therefore be understood in the broadest meaning of the term. Such a material 3 may also be a rubber, and thus the term 'plastic' must herein be understood to also include rubbers, although these are not normally classified among the materials despite having in common various similarities from both the chemical and the technological point of view. The multilayer material according to the present invention further includes a metal layer 4. Such a metal layer may consist of one or more foils, a sheet, a micro-perforated, perforated or solid surface foil or sheet. The metal layer 4 may further consist of a mesh structure or a weave of fibers and foils and/or sheets of bi-metal materials. The metal material employed to make the layer 4 may be any material. For example, iron and alloys thereof may be employed, including all types of steel, copper and alloys thereof, aluminium and alloys thereof, lead, titanium, gold, silver, and the like.
The thickness of the metal layer 4 greatly affects the deformability and mechanical strength properties of the finished product, as well as its thermal and magnetic conductivity.
In order to make the multilayer material according to the present invention, it is possible to either adhere the layer of plastic material 3 to the layer of fabric 2 and then apply the metal layer 4, or firstly deposit the plastic material 3, e.g. by spreading, on the sheet or foil or mesh of metal material 4, and only later adhere the group made of plastic layer 3 and metal layer 4 to the fabric 2.
The plastic materials of which the plastic material layer 3 consist may indeed by heated to the softening point even more than once, without the later heating negatively affecting the mechanical and physical properties of the material itself. In virtue of this, the production process of the multilayer material 1 according to the present invention may be split into two distinct steps, if this results to be advantageous. As mentioned, it is possible to apply the plastic material layer 3 on the fabric 2 by spreading, for example, and then proceed with the positioning of the metal material layer 4 either immediately, when the plastic material is still in a softened condition, or by heating said plastic material again after cooling down the material to allow the product to be stocked during an intermediate step of machining. Practically, the metal material is immersed into the softened plastic material 3, thus reaching the condition shown in figure 2.
When the plastic material cools down, it solidifies and incorporates the metal material layer 4.
Alternatively, as mentioned, it is possible to spread the plastic material 3 on the metal sheet 4 and only later adhere the intermediate product thus obtained to the fabric 2. Also in this case, it is possible for example to split the production process into two steps, if it is advantageous to produce for example a certain quantity of intermediate product consisting of the metal layer, previously cut and coated with plastic material, and only later, e.g. after receiving an order from a customer, proceed with the assembly of the finished product by adhering the intermediate product thus obtained to the fabric layer by then heating again to soften the plastic material itself.
With particular reference to figure 3, in a second preferred embodiment of the multilayer material 1 according to the present invention it is possible to provide a double layer of fabric 2, surrounding both faces of the metal layer 4, in turn embedded into the plastic material 3.
The properties of the plastic materials herein considered have been seen to allow an excellent hot machinability and, in some cases, such as for example for silicones, they are also cold machinable. This excellent machinability allows to spread even very thin layers of plastic material onto the metal layer and to obtain such a metal layer surrounded by the plastic material itself.
If required, the layer of plastic material 3 may thus be a very thin layer, just sufficient to perform the two-fold function of fully covering the metal material and of acting as a binder or adhesive with the fabric once it has been softened, adhered and then cooled.
Obviously, being the metal material layer 4 either fully surrounded or embedded into a plastic material layer 3 actually makes the metal material itself protected from oxidation, because after the deposition process of the softened plastic material on the metal material there is no oxygen contacting the metal surface, and from external elements in general.
It is possible to deposit the plastic material only on one side of the metal material if the metal material used is stainless.
Naturally, different thicknesses and different mechanical and constructive properties may be also considered for the metal layer. The multilayer material according to the present invention has been disclosed to achieve the proposed purpose and objects.
Specifically, the multilayer material according to the present invention has been disclosed to allow to combine the advantages of tensile strength, deformability and thus transport and storage ease to the mechanical properties of a metal material foil, properties which will vary according to the type of fabric, the type of plastic material used for the supporting layer and the type of metal material used in different thicknesses, different processes and structures. Furthermore, the multilayer material according to the present invention allows to combine the aesthetic advantages of a fabric to the advantages, in functional terms, of a metal foil, thus able to maintain a given shape and to be folded at will. Yet another object achieved by the multilayer material according to the present invention consists in the possibility of making covering surfaces having the deformability, and thus the assembly, disassembly and transportation ease of a sheet, with a higher deformability strength, e.g. in the case of a covering sheet of a structure, the presence of a metal layer allows to avoid the formation of water pockets into the sheet following heavy rain, and possibly a better insulating effect.
It is indeed known that aluminium, for example in the case of thin micro- perforated aluminium foil, has the capacity of reflecting UVA rays and of dispersing heat. The material according to the present invention could thus be employed to make covering sheets with excellent heat shielding capacities simply by providing thin foils of micro-perforated aluminium foil forming the metal layer.
Furthermore, the multilayer material according to the present invention allows to obtain a fabric with a metal core, which may allow to electrostatically insulate an object or an environment by simply wrapping it in such a fabric.
Not least object achieved by the present invention is thus that of providing a multilayer material which has the aesthetic appearance of a fabric but which has the mechanical strength and deformability features, as well as the capacity of maintaining a given shape, of a metal foil. The use of metal layers with different features and thicknesses allows to obtain final products having the most varied deformability features. A yet further object achieved by the present invention is that of providing a material by means of which products of new conception may be made, such as for example a shower curtain or a screen having the exterior appearance of a fabric but which may be arranged in a typical self-bearing and foldable structure of a metal foil. Many changes may be made by a person skilled in the art without departing from the scope of protection of the present invention.
Therefore, the scope of protection of the claims must not be limited by the disclosures or by the preferred embodiments described by way of example, but rather the claims must include all the features of patentable novelty inferable from the present invention, including all the features which would be treated as equivalent by a person skilled in the art.
