Description

COMPOSITE SHIELDING MATERIAL

Technical field

This invention relates to a contrasting material and in particular a composite contrasting to limit at least a part or a component of an electromagnetic wave, that is, to contrast the harmful effects due to electromagnetic waves, in particular microwaves.

Background art

As is known, technological devices are currently widespread for which the operation is based on the propagation electromagnetic waves or which generate these waves, such as, for example, electric household appliances which produce radiation (from low frequencies up to microwaves).

Specific reference is made below to the commonly used mobile telephony devices, such as "mobile phones" or "smartphones", an example of the above-mentioned devices the operation of which is based substantially on the propagation of electromagnetic waves.

In the jargon of the trade, electromagnetic waves with frequencies greater than 1 GHz are indicated as microwaves, to which reference is made below.

Microwave ovens, in particular during the use of mobile phones, determine a heating of areas of the user rich in water, such as, for example, the adipose tissue deposits, located close to the telephone device.

This heating can be considered to be a visible manifestation of the harmful effect of the microwaves on the user, so, for example, cases for these devices have been developed over time for contrasting the effects of the microwaves.

An example of these solutions is described in patent document KR101223506 relative to a protection for mobile phones which allows dissipation of the heat together with a screening of the electromagnetic waves. This protection comprises a layer of non-woven fabric impregnated with shungite.

A limitation of these solutions lies in the fact that the correct operation of the device protected is often compromised; moreover, the operations of impregnating and applying the non-woven fabric are particularly complex. In general, any device for which the operation requires the generation or in any case the transmission of microwaves can be considered to have harmful effects on the biological tissues of the generic user.

Patent document JP3922039 describes a material, and the respective applications, capable of totally absorbing the electromagnetic waves generated by an electronic device since it is a potential cause of disturbance for nearby apparatuses. The material is placed in absolute proximity to the source of these waves which are completely absorbed. The application described cannot be used, for example, in mobile phones as it would prevent the operation.

Disclosure of the Invention

In this context, the main aim of this invention is to overcome the above- mentioned drawbacks.

The aim of the invention is to provide a material which contrasts at least one component of the electromagnetic wave and is able to reduce the harmful effects of the electromagnetic waves, in particular in the frequency of the microwaves.

A further aim of this invention is to provide a contrasting material and a use of the contrasting material which, whilst reducing the negative effects of the electromagnetic waves, allow the correct operation of the electronic devices in question.

The technical purpose indicated and the aims specified are substantially achieved by a contrasting material according to claim 1. Detailed description of preferred embodiments of the invention

Further features and advantages of the invention are more apparent in the non-limiting description which follows of a preferred non-exclusive embodiment of a composite contrasting material according to this invention.

The composite contrasting material according to this invention comprises a first plastic and/or metal component and a second component comprising natural conjugated fullerenes, present for example in the shungite which is preferably used in making the material according to this invention.

For simplicity, reference is made below without distinction to the shungite and to the natural fullerenes joined together.

A sufficient mass of shungite is present to achieve an effect for contrasting the harmful effects of the electromagnetic wave within a predetermined radius of action, as explained in more detail below.

The term composite is used to mean that the material is formed by joining two or more elements.

Shungite is a known natural material and it is, in short, a non-crystalline mineral consisting of various percentages by weight of carbon.

Generally, the shungite comprises from 5% to 98% by weight of carbon. Of particular importance to this specification, as described in more detail below, is the presence in the shungite of natural conjugated fullerenes. The shungite is preferably present in the contrasting material in the form of powder.

As explained in more detail below, the shungite is preferably present in the contrasting material in the form of powder in suspension made of plastic or metal material.

In a preferred embodiment, the first component is metallic and the contrasting composite material is defined by a metal alloy comprising the first metallic component, preferably aluminium, and the shungite.

The metal alloy is preferably obtained by fusing together the first and second component. In the case of composite material comprising aluminium, the mixing of the aluminium with the shungite is preferably carried out hot.

In a second embodiment, the first component and the second component are combined such as to define a mixture comprising the first component and the second component.

In particular, the above-mentioned mixture is a plastic mixture wherein the first component is plastic preferably comprising Nylon and/or ABS and/or PVC and/or PET and/or PLA.

The composite material thus obtained is in particular a composite plastic material wherein the shungite powder is dispersed in the first plastic component.

For example, in a preferred embodiment, the plastic material and the shungite are mixed hot to obtain the composite material.

In a preferred embodiment, the first component is metallic and the contrasting composite material is defined by a metal alloy comprising the first metallic component, preferably aluminium, and the second component consisting of shungite powder, incorporated in a plastic material.

In other words, this invention comprises a material comprising a metal alloy, comprising a first metallic component, preferably aluminium, and the shungite, incorporated in a plastic matrix.

The composite material thus obtained is moulded or used for a three- dimensional prototype production of substantially known type to obtain corresponding products.

The percentage of shungite present in the composite material depends on the type of shungite.

More specifically, to obtain a satisfactory screening effect for contrasting the negative effects of microwaves, it is necessary, as explained in more detail below, that the quantity of shungite used in the material allows an adequate level of natural conjugated fullerenes to be achieved in the composite material. More specifically, the natural conjugated fullerenes brought by the shungite are preferably present in a quantity of between 5% and the 45% by weight of the composite material.

According to a preferred embodiment, the second component comprises grade 1 shungite (shungite-1 or shungite elite) present in the contrasting material in a percentage comprised between 5% and 20%, preferably comprised between 5% and 14%.

The shungite-1 is, in general, shungite with a carbon content of between 80% and 99% by weight.

According to a preferred embodiment, the second component comprises grade 2 shungite (shungite-2) present in the contrasting material in a percentage comprised between 15% and 50%, preferably comprised between 15% and 44%.

The shungite-2 is, in general, shungite with a carbon content of between 30% and 79% by weight.

According to a preferred embodiment, the second component comprises grade 3 shungite (shungite-3) present in the contrasting material in a percentage comprised between 30% and 95%, preferably comprised between 45% and 95%.

The shungite-3 is, in general, shungite with a carbon content of between 5% and 29% by weight.

The shungite included in the composite material screens it against one or more components of the electromagnetic waves, in particular certain components of the microwaves, in order to reduce the heating of the biological tissue affected by these waves.

This invention also relates to a use of the shungite in a composite contrasting material in combination with at least a further component, in particular the use of the shungite in a metal alloy comprising at least one metallic component, in particular aluminium and/or the use of shungite in a plastic mixture, comprising at least one plastic component. This invention also relates to a use of the shungite in a plastic mixture comprising at least one plastic component and loaded with at least one metal component, for example aluminium. This invention also relates to a contrasting product comprising or made with a composite contrasting material as described above.

The preferred use of the material according to this invention is to contrast the harmful effects of the electromagnetic waves by positioning the material around the source.

More specifically, the applicant has observed experimentally that a product made with the material according to this invention defines a "contrasting field" or "field of influence" inside which the electromagnetic waves do not influence the organic material.

The contrasting field is a function of the mass of the above-mentioned product.

In practice, a product made with the material as described and having a predetermined mass, generates a field in which the electromagnetic waves no longer influence the organic material.

The radius of action of this field, that is, the extension of the field in which the electromagnetic waves do not influence the organic material, is a function of the mass of the product.

In other words, this invention relates to a product capable of contrasting the harmful effects of the electromagnetic waves. The combination of shungite with other plastic or metallic materials, or both, makes it possible to use the natural conjugated fullerenes which otherwise might not find use. The products thus obtained, even if not directly used in the screening of devices generating electromagnetic waves, are advantageously applied in the definition of a contrasting field, the radius of action of which depends on the mass of the product.

More specifically, it should be noted that, with the product according to this invention, it is not necessary that it is interposed between the source of the electromagnetic waves and a subject is struck by them. For example, the following tests carried out by the applicant are considered.

Test conditions:

Contrasting material + 2 mobile phones (iPhone 6 plus caller and iPhone 5 receiver); the subject considered is the receiver of the call.

A product according to this invention has been used in particular in the shape of a sphere positioned on a supporting base.

The sphere consists of PLA + grade 2 shungite for a total of 450 grams and the base consists of PLA + grade 2 shungite for a total of 150 grams

(mass of 600 gr, of which grade 2 shungite micronised to 20 microns equal to 450 grams).

The calling mobile phone was positioned at 6 metres from the receiving cell phone.

Ambient temperature thermo-regulated to 29.3°C +/- 0.2°C.

An NEC InfReC R300sr infrared video camera: resolution 640x480 pixels thermal sensitivity 0.025°C has been used to acquire thermographic images of the subject during a call between two mobile phones.

More specifically, calls have been made with a duration of 12 minutes and videos have been taken, at 30 frames/second, with the above-mentioned device.

It should be noted that for each video there would be 21 ,600 frames which are rounded up to 22500 for each test.

By convention, the receiver holds the telephone on the right resting at the top on the edge of the ear and at the bottom displaced by approximately 5 cm (the phone is moved away from the face every 3 minutes for 10 seconds).

TEST 1.

Sphere placed at 2.5 m from the receiver: no increase in the temperature of the face of the receiver is recorded. TEST 2.

Sphere placed at 3 m from the receiver and there is no increase in the temperature of the face of the receiver in 12 minute call.

TEST 3.

Sphere placed at 4 m from the receiver and there is no increase in the temperature of the face of the receiver in 12 minute call.

TEST 4.

Sphere placed at 4.5 m from the receiver and there is no increase in the temperature of the face of the receiver in 12 minute call.

TEST 5.

Sphere placed at 5 m from the receiver and there is no increase in the temperature of the face of the receiver in 12 minute call.

TEST 6.

Sphere placed at 5.5 m from the receiver and after a 12 minute call there is a clear increase in the temperature of the face which already after 3 minutes changes colour from yellow to red in the temporal area to the right (where the mobile phone is held), the colour change becoming more evident after 6 minutes and 9 minutes whilst after 12 minutes the right half of the neck and neckline have changed to red and the left part in the parietal area is as in the initial conditions and the increase in temperature is limited on the left to the part of the tear duct of the eye, to part of the front and to part the neck.

The applicant, on the basis of above-mentioned results, highlights that the radius of action of a product according to this invention, in the shape of a sphere, consisting of PLA + grade 2 shungite for a total of 450 grams + base consisting of PLA + grade 2 shungite for a total of 150 grams, is at least 5 m. Tests of this type carried out with products according to this invention comprising grade 2 shungite and PLA have been compared with tests using grade 2 shungite in its natural state; these tests demonstrate, in various types of objects of various sizes, that the radius of action is a direct function of the mass according to the following relationship "Mass gr / distance in cm = 0.8975".

A different test found that a product according to this invention in the form of a bracelet worn by a person and positioned 70 cm from the ear prevents heating of the face, as shown by a video camera of the type described indicated.

Similarly, a product in the form of a pendant weighing 6 grams (PLA + Shungite), above the solar plexus 40cm from the ear prevents heating of the face of the receiver.

The Applicant has also carried out analyses performed with "Rayonex©" bio-resonance apparatuses which have demonstrated that in a room where there are 2 mobile phones in mutual communication and a product according to this invention in the form of 2.5 cm plate there are no disturbances of the electromagnetic field.

The applicant has observed, by means of a Rayonex© bioresonance test, that the two mobile phones in the above-mentioned room were balanced (field of microwaves).

Three products according to this invention have been identified as being responsible for the re-equilibrium, in particular two plates made of PLA and grade 2 shungite, weighing grams 6 each adhered to a respective mobile phone and a size S bracelet, located on the floor which the Applicant has demonstrated to have a radius of action greater than 1 m.

After eliminating the two plates and the bracelet the same test in the microwaves field has shown, during the conversation, a lack of balance accentuated by the fact that both the mobile phones were present in the same room. Advantageously, a product according to this invention may be used to reestablish an energy re-equilibrium.

The invention described brings important advantages.

Using the natural conjugated fullerenes, for example present in the shungite, mixed or linked in the ways described for example with at least one other component, it is possible to use the characteristics for contrasting the negative effects of the electromagnetic waves and re- equilibrium of the waves of the physiological electric field.

More specifically, the properties of the shungite are substantially due to the organic component defined by the natural conjugated fullerenes and to the particular combination of rare earth and ferrous alkaline, of lanthanides.

These properties are also due particularly to the polarisation of the natural deposit for extraction of the shungite.

The composite material thus obtained may be used in the production of technological devices which produce radiation or products which may contain the harmful effects of electromagnetic waves, in particular microwaves, defining a sort of the contrasting field for one or more components of the product.

The combination of the natural conjugated fullerenes, in particular of shungite, with other plastic or metallic materials, makes it possible to manufacture these products which are advantageously applied in contrasting harmful effects of electromagnetic waves.

Advantageously, the effectiveness of the composite material according to the invention increases with the increase in the frequency of the electromagnetic wave, reaching the maximum effective in contrasting the harmful effects of microwaves.

This composite material can advantageously be used in the production, for example, of electric household appliances, phones cases, control units for vehicles, garments or clothing accessories, or the chassis of electric household appliances which work with the electromagnetic emissions so that they no longer produce harmful biological effects. The natural components present in the shungite minimise the component of the electromagnetic waves which is harmful for biological tissues (microwaves in particular), without neutralising the electromagnetic wave, that is to say, without the electromagnetic wave losing its effectiveness in particular in terms of signal carried.

Indirect experiments carried out by the Applicant on the emissions of mobile phones have shown that the natural conjugated fullerenes reduce the increase in the temperature caused by the microwave on the biological tissues at the telephone device but also within a radius of action of the product made with the material according to this invention as a function of the mass of the product.

The composite material according to this invention uses the neutralisation of the biological effects of the electromagnetic waves determined by the components making up the shungite comprising shungite together with at least a further component.

Examples of products which can advantageously be produced, either entirely or partly, with the composite material according to this invention are processors with frequencies of from 2500 to 4400 MHz, 2/3D televisions with a frequency of from 1750 MHz to 3000 MHz, tablet PCs with a frequency of from 1750 MHz 3000 MHz, electrical household appliances with a frequency of 500-3000 MHz.

Further examples are shown below of materials which may form the first component of the material according to the invention, that is to say, materials which can be fused and/or mixed with shungite.

As already mentioned, the materials obtained in this way allow the negative effects of the electromagnetic irradiation to be limited, if not eliminated, without affecting the functionality, for example in the telephone sector. The electromagnetic field of the mobile devices is not directly influenced; more specifically, the materials according to this invention let through, without disturbing them, the carrier component of the electromagnetic wave whilst the resulting component, considered responsible for harmful effects on biological tissues, is limited.

The electromagnetic waves, in particular the microwaves, are not significantly weakened in their entirety when passing through the contrasting material according to this invention.
