Description

SECTOR OF THE TECHNIQUE

The present invention belongs to the sectors of the glass industry, thermal insulation and more specifically to objects designed to resist the weather, protect from sunlight or heat caused by fire, either by tarpaulins, fabrics or covers .

The main object of the invention that is recommended is an elastic cell glass canvas or cover or the equivalent of calling it a cell-shaped transparent silicone canvas or cover. The necessary combination between; The elastic material that forms it, the internal structure, the union between the parts and the color as an inherent optical property, is what manages to offer levels of insulation and protection among other qualities, which has not been achieved in current canvases or roofs.

BACKGROUND OF THE INVENTION

Since it has also been considered as the title of the invention that is recommended, that of simply canvas or improved cover, it has finally been preferred to be referred to as canvas or elastic cell glass cover because the holder of the invention wishes not only to better expose the invention, but also to reveal that elastic glass as a material, is a reality among us even if it is somewhat disconcerting. However, the elastic glass in cellular form, is something that is not known and less taken to an object for insulation or protection similar to a canvas, fabric or cover and that can even float on water.

It is known that there are as many types of tarpaulins or protective covers as there are types of suitable materials we have to make them, but in no case of glass. In view of the object of the invention, in order to better warn the state of the art that is advancing, it is considered necessary to explain more fully the material of which the invention is made. Therefore, a brief subsection of the origin and historical background of both glass and glass and its controversies is made.

Nowadays, in some countries there is talk of glass and glass interchangeably, when for many it is not correct. For example, the Anglo-Saxon word Glass is used in the same way for both objects, either to refer to glass or to refer to a glass and without making semantic distinction. For some theorists and scientists of the matter it is a mistake and for others it is not. If we attend to a plain and non-technical or exhaustive language, the dictionaries themselves commonly define glass as toughened, transparent and colorless glass,

which is obtained from the high temperature melting of mainly silica and some oxides. If we look at the glass itself, it is defined as a transparent or translucent substance, hard and fragile at ordinary temperature, which is obtained by melting a mixture of silica with oxides and small amounts of other bases. Either one definition or another, it is important to highlight and remember for later, that both definitions unambiguously allude to having optical properties related to more or less transparency. Something fundamental to understand later what the invention advocates.

Mr. Jose Maria Fernández Navarro of the Higher Council for Scientific Research, in his book called El Vidrio (3rd Edition, Madrid - 2003), tells us about the paradoxes and discrepancies that, from their own etymology and origin, occur in the word glass. Word that is born mainly inspired by the characteristics that some materials and elements present in their natural state, such as ice, amber or quartz. Going deeper and taking care not only of its superficial aspects, we see how the problem of definition and distinction is still referred to in a systematic attempt to establish the differences between glass and crystal. For this purpose, a comparison is made of the study of its vitreous states or the processes to obtain them, the same chemical composition and molecular structure, and even the geometry and mechanics offered by each material by virtue of achieving that more explanatory differentiation or a more defined definition. accepted by all. However, different non-unanimous positions are offered, either according to the author, association, scientific academy and even according to the country, where there is a lot of disappointment. As Mr. D. Maria Maria Fernández Navarro states in his book, some extend both the concepts and definitions, which would not give rise to clearly distinguishing the glass from the glass and others, restrict it so much to specific issues, that one would have to talk about crystallized glasses

or glazed crystals to put it in some way.

The least dispersed differentiation found is that derived from distinguishing them by recognizing the molecular structure of both materials. Thus we could say that the molecular structure of a crystal, worth the redundancy, is formed by crystalline solids, that is, its molecules have a diffraction pattern that is not diffuse and well defined. Or in plain language, its internal structure has a regular geometry. And yet, a glass, they form it, solid amorphous ones that are those that present an irregular pattern of atoms or ions formed of three-dimensional molecular structures without periodic ordering. Well, it is the molecular structure of atoms, the first factor by which it is determined that the object of the invention described below, although similar in composition

chemical and molecular to some crystals, it has not been qualified as a type of crystal and this term is discarded in any of its denominations.

Precisely, continuing with the search and analysis to find a name of rigor to the material object of the invention, for more Inri, although now in a positive and decisive way, it is found that a part of the scientific community asks the following question. Is glass a polymer? Citing the polymer expert and professor emeritus D. Lon J. Mathias of the School of Polymers and High Performance Materials of the University of Mississippi, he quotes us on his didactic website, this dilemma and makes a call in case someone can contribute any idea. He argues that, indeed, the molecular structure of common glass, the same that we find in vases or windows, is composed of a molecular structure whose arrangement of atoms indicates us to be amorphous. And as it was introduced above, it is a basic difference with the crystal. Now, taking into account its chemical composition, most of said glass is made from sand, from the same sand what we call silica is extracted, which is usually melted with sodium carbonate to give it greater resistance. Therefore the main chain of said compound is made of the silicon atom and not of the carbon, which qualifies it as inorganic. Next the question that is asked is whether that same structure, of a common glass and well recognized by society, can be considered as a polymer since, although the main chain of polymers is usually carbon, there are many polymers also accepted as inorganic . This detail is very important to remember for the purpose of our argument to the denomination of the object of the invention.

For example, if we talk about common silicone, it has a great structural coincidence in molecular terms and chemical composition, as the same glass previously exposed. It is also obtained from the sand as raw material, from which silica is also extracted, to then obtain a larger compound called siloxane. A multiple siloxane or polysiloxane is represented as having the silicon molecule as its main chain. If these polysiloxanes are interlinked in association with each other, we determine a molecular structure like that of the same glass vase discussed above. That is, it seems that the same main chemical composition and molecular structure of the common glass that Professor D. Lon J. Mathias presented to us is presented in silicones. Therefore, from this point of view, there is no reason to stop stating that glass can be considered an inorganic polymer and that it also has the same molecular structure of silicone (whose improved designation is that of crosslinked polysiloxane).

With which both glass and silicone, have an amorphous arrangement and silicon main chain.

If we previously discarded the term crystal to designate the invention that is recommended, now we go further and say that reached this point, now we could not discard the word glass to define it since it is made of silicone. Therefore, it follows from the analysis that a silicone could be considered an elastic glass. Which is understood to be strange in colloquial language because of the difficulty of disinfecting the term glass, a quality of less hard or even soft and less stiff and even elastic.

Now, the next question to answer is whether any silicone, whether in its common solid state, gel or foam, can be considered a glass. We have seen that both the term crystal and the term glass, accompany by definition the qualities of colorless, transparent or translucent and therefore alludes, both technically and socially, that both have such optical property. It is for this reason and in view of finding a convergence, which in this case isolates controversies of definition, that it is proposed that not all silicones can be considered glass, without depending on whether their state is solid, gel or foamy but mainly on the color that causes the incidence of light on said material, that is, the color that appears in view of the human eye that is used as a parameter of measurement and generalized recognition. Since, whether it is an opaque, translucent or transparent material, it is fundamentally indicative of the same chemical composition and molecular arrangement of the compound or object.

In conclusion, a silicone can effectively be considered a glass, but not just any type of silicone. That is why it is conditioned to the existence of transparency and / or translucency in silicones to be considered as such although we have not integrated it into our semantic and popular schemes. Therefore, a silicone can be considered glass as long as it is translucent or transparent. Likewise, the figure or element that conforms to a silicone, could be called elastic glass, given its inherent elasticity property or simply silicone glass, if as a whole said object allows light to pass through, either translucently or transparently to the human eye . Thus it is discovered, that both technically and in a popular environment, elastic glass, it is not only possible to realize it but that it already existed among us in objects made of silicones that are perceived translucent or transparent to the human eye, either in solid form, in gel form

or liquid In the same way, we cannot consider it crystal as long as it is based on

a main chain of molecules whose arrangement is amorphous and irregular, even if only in some of the layers of the same and although it seems crystalline in appearance.

Now that the concept of elastic glass is argued and discovered that it already exists among us although disguised as transparent or translucent silicone, there is a better predisposition to talk about the background closest to the state of the art of the canvas or covered with elastic cellular glass.

Taking into account the most common concept of glass, whether used for windows, vessels or bottles, it is understood that it is hard and rigid glass, making its use unthinkable and unthinkable for applications such as canvas or blanket, it is say, they have no elasticity. Likewise, common glass by itself does not contain air or gas enclosed inside, so they are not able to increase their thermal insulation, for example by incorporating air or gases as an insulating barrier in their manufacturing process. Yes they are found, compositions of double and even triple glass mounted on window frames, which leave a cavity or space between them to achieve this purpose, the AislaGlas © is one of them. But in any case, they are still hard, rigid and heavy without bending them without breaking them. The invention advocates a flexible and elastic glass that by itself can achieve the insulation effect produced by containing air or gas inside.

On the other hand there are the so-called organic glasses; plastic polymers of translucent and / or transparent color that allow light to pass and that can be configured as soft or flexible by making thin sheets but are not elastic in nature, such as; PVC, polycarbonate or methacrylate. Likewise, these materials have been made in various shapes and structures, such as cellular polycarbonate, which leave gaps inside but that, in addition to not being elastic, these arrangements make them more rigid. In addition, it is noted that the cellular structures that they present, have hollow cavities

or your cells are not closed. With which they have not been designed with the purpose of containing air or gas. In both cases, their stiffness makes it not feasible to conceive of them as canvases or elastic covers and they do not prevent overheating itself from direct exposure to the sun's rays. The invention that is recommended is a glass, therefore translucent and / or transparent, which presents elasticity, reduces its own density allowing even buoyancy over water and manages to avoid its own overheating. It even manages to keep the surface exposed to the sun's rays fresh, at levels where the rest of the materials used for tarpaulins or covers do not succeed.

With respect to translucent or transparent silicones, commercially referred to as crystalline silicones and which, as discussed above, can be considered as elastic glass, neither are canvas designs or covers with said material found in the current state of the art. Yes, they have their own elasticity and necessary to be folded without breaking, but their intrinsic density and weight is so high that it does not float on the water by itself, complicating, for example, its use as a pool cover canvas

or act as a protective insulator that prevents overheating by not containing air or gas chambers inside. The canvas or cover object of the invention is made of this same material but it is able to reduce its weight remarkably and therefore its density, to the point of allowing its own floating on water and thus use it as a pool cover.

In reference to the pool covers, there are those that also have the ability to float on water, but are made of plastic with air bubbles, material that degrades more easily to the weather and direct exposure to the sun's rays . Likewise, these plastics are prone to the appearance of mold having to use chemical treatments that can then reach the water. The canvas or cover object of the invention is made of a material, structure and color, which altogether avoids said problems.

On the other hand, although there is no evidence of the existence of canvases or covers mainly made of silicone foam, since given its technical and physical-mechanical characteristics they would not make it suitable for such use, but, although there are not only technical differences but also functional, an introduction is made below because of its proximity to the invention, which is recommended for both a specific type of foams of recent design, cellular silicone foam, and traditional silicone foams.

When a material is brought to its foam state, generally, its purpose is to try to reduce its weight or give the material greater flexibility. We find documents that talk about improving the density of elastomeric foams, from physical-chemical processes, whose reactions cause something like molecular expansion, that is, they cause foaming or gasification of the material by expanding the air gaps or other substances. For example, documents EP 0341469 B1 (David Charles Gross, Connie Lee Haig, Jonathan David Rich), US 5011865 (Donald S. Johnson) and ES 2 061 830 (Smith, Kennith Allen and Haig, Connie Lee) are cited as Through them we will get to know the rest of patents with ease. These in particular, speak of a silicone foam with molecular structure of bubbles or closed cells inside and claims a method to reduce the density of a silicone foam and chemical compositions. They can meet

open cells or pores or closed pores, but in any case their formations are circular and random and uncontrolled in size and places, something like soap bubble foam. In addition, some speak of a process of foaming or gasification, which manages to lower the density of the silicone significantly (around 150 kg / m3) but losing much of its resistance and therefore resulting in easy breakage, with little consistency. This group of inventions in addition to moving away from the invention that is recommended for its material structure and its function for which they were created, none refers to embodiments or claims with or on the translucent and / or transparent color, without thinking of conferring them properties optical, its colors being generally opaque to light.

Other patent groups, such as WO 2014039414 A1 (Junkang J. Liu, Pingfan Wu, Feng Bai, David A. Ylitalo), speak of different compositions of superimposed layers or layers of silicone. It is convenient to clarify its interpretation by entering its descriptions, since the invention that is recommended also speaks in its description of layers or sheets. It is noteworthy that the layers to which this group of patents refer, refers to different sheets in compositions on top of each other, designed in sensor coatings and electronic protection, but in no case are they separated from each other leaving spaces or gaps by means of possible prismatic structures, cells or partitions as the invention that is recommended.

Other patents that are found and that do have prismatic silicone structures such as those presented by the invention, are the HEXALITE TM technology of the late twentieth century, which was used commercially, among other applications, as a shock absorber inside the Sneakers soles. The document is described in US 6245408 B1 (Thomas N. Bitzer) and describes a layer of hexagonal prisms attached and open on both sides, the equivalent to the transverse half of a honeycomb or what is the same, only one side of the same. From there, the sandwich structures were extended although thought and made with various rigid materials being that the parts are joined by some kind of glue and not by fusion. More recently, document ES 1129555 U (Arturo Carrillo Sánchez), with the trade name BEESTRUCTURE ©, reveals the filling structure made of elastomer formed by multiple layers of multiplicity of open and attached or stacked prismatic cells, forming tiled and homogeneous surfaces. For example, in relation to the same one type of cushion is already on the market, which although it shows translucency or transparency and is made of elastic polymers, it does not have the shape or design that makes it possible to use it with a canvas or protective cover. But the most important difference with the invention is that

It is essential that it does not leave inside tightly sealed spaces that make gas or air chambers.

Ultimately, in terms of foams, whether they are traditional silicone foams with random pores or the last foams achieved of cellular silicone with internal prismatic structure, open or closed cell, in addition to the fact that among its uses the realization in form and purpose as that of a canvas or protective cover, neither in its own claims, does something arise that has to do with its own color. Therefore, among them, it has not been considered that the incidence of light has been something decisive or decisive to take into account in their own state of the art. They have been designed for functions of filling of gaps or spaces, electronic protection or in search of elements of cushioning and comfort associated with other materials, generally being mostly opaque to light. And those that are not and that show translucency or some transparency, have not been made or found claim on possible air or gas chambers, inside.

Ending with a direct allusion about the main use of the invention, the tarpaulins or roofs currently existing, whether for swimming pools, boats or for loading and unloading trucks, with the purpose of protecting from sunlight, cold or heat , are usually made of opaque materials. This presence of color, together with the other materials of which they are made, in order to increase their resistance to inclement weather, weathering or continuous manipulation, causes them to usually overheat and even burn on contact with the skin. Although they are flexible and manage to adapt to the surfaces or reliefs of their surroundings, these materials are not elastic in nature. On the other hand, translucent canvases made of some organic plastic have been found, in no case elastomer, composed of a twisted of wires that let the light through, preventing overheating. But in addition to the fact that the material of these canvases degrades more easily than the material of the invention, they do not contain air or gas chambers. Being neither able to prevent the proliferation of mold or microorganisms by themselves, having to use additional chemical substances in some cases. The invention that is recommended in addition to being more resistant to the weather, withstand aggressive environments such as saline, acting as an insulator and thermal blanket, is characterized by the novelty of not suffering from overheating when exposed to direct sunlight. Likewise, unlike the rest of canvases, you do not need additional anti-mold or anti-bacterial treatments.

In conclusion, they have not found in the market or in official documents, articles that demonstrate or claim as a whole the qualities of; material, structure and color presented by the invention that is recommended. Being an important factor the combination of the 3 qualities to achieve the results and properties it offers. That is, they provide the invention with innovative technical and physical-mechanical properties that are not in the current state of the art.

DESCRIPTION OF THE INVENTION

The invention advocates an elastic cell glass canvas or cover, characterized by 2 silicone sheets separated from each other, an internal structure of the same material as partitions fused with the sheets leaving cells or closed chambers and a translucent and / or transparent color . Therefore the necessary combination between; material, structure, union between the parts and color, is what manages to offer the qualities and properties that do not appear in existing canvases or covers.

The material of the invention is silicone, which in itself is a material that does not degrade outdoors and withstands extreme temperatures that can range from -50º to 250º. Likewise, unlike other plastics or synthetic materials used for tarpaulins or covers, it prevents the appearance of mold and micro organisms. But silicone itself is heavier in relation to the materials or compounds that are usually used for tarpaulins or covers. Its density exceeds 1000kg / m3 and for example it is not a material that itself can float on water. That is why it has been carried out in a cellular way leaving cameras or cells tightly closed by means of 2 silicone sheets separated from each other with a thickness that allows both their own winding manually and can also adapt to surfaces, whether they are rigid with roughness or soft and changing like water. Said separation has been made by means of structures of the same material fused together to both sheets. They act as a support or partition to keep the sheets separated. The sheets cannot touch each other in their resting position but they can be touched when folded thanks to their elasticity. In a preferred embodiment, an interior space has been left that separates the sheets 3 millimeters from each other, being that as a whole, the thickness is 6 millimeters. For example, these measures are sufficient to allow their handling and winding as well as their buoyancy over fresh water. This is how spaces or cells are created inside that as a whole reduce their weight and therefore their density, in proportion to the volume of air or gas they house. With this

We manage to combine all the protective properties that silicone has intrinsically with new ones that allow us to think about its practical and technical use as a canvas or cover.

But the invention advocates a tarpaulin or cover not only of cellular silicone but speaks of an elastic cellular glass that in addition to all of the above is capable of letting light through and prevents overheating that the rest of plastic materials suffer with direct sun exposure. For this it is necessary and decisive, as explained more deeply in the background of this report, that the canvas or cover is transparent or at least translucent, more technically, that the canvas or cover obtained has the optical property to emit translucency or transparency before the incidence of light on it. For this, translucent and / or transparent colored silicone is used with the same configuration described above. Said silicone, not opaque, has the conditions of molecular structure, chemical composition and optics, to be considered as an elastic glass as explained and scientifically argued in the background. Therefore, the realization of the canvas or cover of cellular and elastic glass at the same time, is obtained from the combination of material, structure and color required as just described. More simply, we can also refer to it as a canvas or a transparent and cellular silicone cover.

With this embodiment, in addition to; reduce density and weight as for a better handling and even buoyancy in fresh water, maintain all the intrinsic properties offered by silicone, increase its thermal efficiency as a new insulator, the absence of color gives new properties to the whole canvas. It makes the incidence of light and more specifically the sun's rays will not affect as strongly as the rest of plastic materials for 2 reasons, the material and the color. It is known and demonstrated by optometry that materials absorb different spectra of sunlight, from ultraviolet to infrared, so that they can be heated to a greater or lesser extent. Color is a quality of objects but not something intrinsic to them. So, for example, something we see white, absorbs less heat than something we see black. That is why when we see the transparent or translucent color reflected in some things, we must resort to the physical, geometric and molecular properties of the material to know and measure its true response to the sun's rays. In short, the face of the canvas or covered with elastic cellular glass, which is in direct exposure to the sun's rays, does not suffer from overheating in the sun's rays than the other canvases. In no case, get to produce the typical sensation of burning on contact with the skin and at the same time protects the objects that are under it even if it is translucent and / or transparent. As a whole, the

Canvas or elastic cell glass cover reflects heat radiation, while natural light penetrates with barely any obstruction. Something that until now had only been achieved in windows composed of rigid double glazing, an intermediate chamber and some solar control sheet material.

To increase the capacity of the canvas or roof as a thermal insulator and prevent heat from being transferred from one side to the other by means of some of the conduction, convection or radiation processes, the structure of the canvas has been made in other sizes of the chambers, thickness of the walls of the sheets and their partitions, as well as color variation incorporating pigments or dyes. Variations between the geometry of the structure, the amount of silicone material used and the color, respond to improvements in its capabilities as an insulator and sunscreen. Likewise, in another preferred embodiment several canvases have been fused together, verifying that the heat impedance is improved. However, the latter responds to the fact that the canvas becomes stronger and more resistant to the detriment of flexibility and elasticity that can make its manual winding more or less forced.

Given the amount of variations and combinations, it is not possible to determine an exact thickness from which we can consider that it cannot be rolled. That is why the invention that is claimed claims this quality, that of roller, to give it a canvas or cover treatment without determining the maximum thickness, density or number of fused canvases that it would admit. For the tests, if it can be affirmed, that at the moment that it cannot be rolled up in a manual and not forced way to keep it in that state, we would be talking about another material, either a silicone foam or a cellular silicone in its case , but not of a canvas or cover of elastic cellular glass. This is so because these embodiments lose the necessary optical property of at least emitting translucency and therefore do not let light through.
