<< INSULATED PANEL FOR CIVIL AND INDUSTRIAL APPLICATIONS AND RELATED MANUFACTURING PROCEDURE WITH INNOVATIVE INSULATED FLUID MIXTURE >>

The present invention relates to an insulated panel for civil and industrial applications and the relative manufacturing process with an innovative insulating fluid mixture.

The insulation? a technique usually used both in the civil and industrial fields to thermally and acoustically insulate an environment or an area, whether for residential or work use, in order to give it different thermo-acoustic conditions compared to another environment or another area, so that the two environments or zones do not exchange heat and sound between them. In this regard, in the prior art, yes? instead of insulation, we usually talk about thermal and acoustic insulation or simply thermo-acoustic.

Insulation, in both civil and industrial buildings, is carried out by interposing specific materials between the two zones or environments to be thermo-acoustically separated, in particular paneling or panels of various sizes, which are capable of preventing heat exchange, in which case it speaks of thermal coat, or the exchange of vibrations, in which case it speaks of acoustic insulation.

In both these construction fields, civil and industrial, insulation plays an important role both for technical reasons, but also, above all, for the achievement of new and better energy efficiency criteria, involving all phases of design, construction and management of the building project .

The thermal insulation of the walls of a building, if carried out correctly and adequately, allows, for example, to reduce the heat flow from inside the living environment to the outside, when the latter is ? more cold, as well as to reduce the noisiness? of the external environment entering the internal environment and vice versa.

In a purely acoustic environment, sufficient thermal insulation can have a minimum value and, conversely, in the field of thermal transmittance, acoustic insulation has an equally minimum value.

In this regard, an example? given by professional acoustic treatments for music or scientific surveys, which include, in addition to insulation, an adequate treatment of the internal acoustics of the area to be isolated, with sound-absorbing geometries and treatments, as well as appropriate acoustic correctors, in order to optimize and make linear the frequency response and amplification of the sounds that are produced by the same area that must be isolated.

Another example ? given by the insulation of the cavities to prevent both the sounds inside the area to be isolated from leaving and the sounds from the external environment from entering, preventing the sounds from reverberating.

The materials used today for the purely thermal insulation of the panels are: rock wool, glass wool, sheep's wool, cellulose fiber, cork, wood fibers, hemp fibers, coconut fibers and for transparent or translucent panels, cellular glass.

The materials used today for the purely acoustic insulation of the panels suitably combine sound-absorbing materials with sound-insulating materials even in multiple layers separated by air gaps.

Examples of sound-absorbing materials include mineral, vegetable or synthetic materials. In particular, among the mineral ones, rock wool and glass wool have a vast use for acoustic insulation works, especially for making the external coat or for the insulation of perimeter walls. These are two fireproof resources, resistant to humidity and mold and economically advantageous, as their porous structure makes s? that the sound wave is effectively absorbed and transformed into heat. Other commercially available and used sound absorbing materials, but more? expensive than the previous ones, are the sound-absorbing vegetable materials such as cork, wood fiber, hemp and jute, which, being porous, play an optimal role in dampening high frequencies, constituting an optimal solution for insulating both environments interiors, for example floors and perimeter walls, and exteriors.

Said sound-absorbing materials are today also made with expanded clay, but usually as panels used to shield the noise caused by vehicles circulating on highways and trains on railways. For this purpose, please note that expanded clay is a material usually used today as a lightweight aggregate for the construction of lightweight concretes and ? characterized by a porous internal core, which guarantees lightness, and a hard external shell which, on the other hand, guarantees its mechanical resistance.

The expanded clay? obtained by cooking clays, of convenient chemical constitution and texture and called cooking? usually carried out in horizontal rotary kilns. The raw material is previously ground with mullers to a granulometry proportionate to that to be achieved for the cooked product. During the heating phase, the raw clay, encountering increasingly higher temperatures, undergoes an increase in volume, as a result of the development of CO2 and the presence of CaCO3 and H2O, since kaolinite and similar silicates are present, with an obvious decrease in its density. specific and related increase in porosity? alveolar. In fact, the partial liquefaction and the rotary motion imparted to the material being fired in the rotary kiln give rise to the formation of spheroids with small cavities homogeneously distributed inside the granule. Once extracted from the furnace, the incandescent material passes through a fluid bed made up of air currents which, in addition to cooling the expanded clay, cause its oxidation and therefore the formation of clinker on the external surface of said expanded clay spheroids. The expanded clay? produced in a large number of particle size classes, cos? to allow a range of lightweight concretes with very different requirements, giving an optimal insulating effect. The small spheroids, usually up to 20 mm, have a high mechanical resistance and are therefore also used for the preparation of light concretes with high compressive strength, precisely called light structural concretes. The compressive strength of lightweight concrete? greatly influenced by the crushing resistance of the granules (UNI 13055-1). Therefore, by carefully modulating the choice of lightweight aggregates, concretes with high mechanical compressive strength can be obtained. Nowadays, in addition to making lightweight concretes, expanded clay is currently also used for various other types of applications that take advantage of its low specific weight, such as for example: filling cavities? underground by injection of dry expanded clay or mixed with cement; the construction of embankments (road, railway, etc.) to be built on land characterized by properties? poor mechanics; backfilling of retaining walls and bulkheads with a reduction in active thrust of up to 75% compared to that determined by traditional soil; construction of crawl spaces, drainage trenches and bedding of underground pipes; as a base in pots for some plants, to avoid water stagnation in the ground; and for making said sound-absorbing panels, specifying that to date they have never been conceived and used as structural elements for building as in the case of the present invention, being more preferred, as mineral components, rock wool and glass.

Other types of sound-absorbing materials include synthetic insulators, which derive from an industrial manufacturing process, such as polystyrene or polyurethane, which have lower costs compared to previous sound-absorbing solutions with a moderate insulating power. Said sound-absorbing materials can be fibrous, such as, for example, glass wool, rock wool, cork, chipboard, fabric and "phonoglass", or with open cells, such as expanded polyurethane, expanded melamine and ?foam glass?.

As far as acoustic insulation is concerned, the specific soundproofing materials are, for example, lead and rubber, the latter being particularly preferred due to its low cost. and ease? processing and installation. Different materials normally used in building, such as, for example, bricks, cement, plasterboard, intrinsically possess a variable soundproofing power.

Soundproofing panels find their use in the insulation of the structural components of a building and are generally used in combination with sound-absorbing materials in order to improve the properties of the building. insulation of the same panels.

To date, to optimize its use, yes ? the continuous search for new combinations in using these materials in combination with other known and less known materials, in order to minimize production costs by optimizing the insulating characteristics of the final product, offering the end user a winning product in terms of quality? and price compared to others on the market.

The above ? understandable for an expert in the art if one remembers, first of all, that in the current structure of the market, not only European, but international, relating to paneling and insulated panels, further performances of fire resistance, mechanical and electrical safety are also required , resistance to wind load, permeability? to? air, permeability? to water, in addition to the usual characteristics of thermal transmittance and noise reduction.

Sound-absorbing panels, therefore, today have the disadvantage of not being inexpensive at all in order to fully meet the standards of performance to which they must be certified in order to be used, such as, for purely tutioristic purposes, in addition to the usual thermal-acoustic insulation, characteristics of resistance to smoke and fire, the performance of integrity? or the performance in response to the behavior of radiation, the barrier effect and the resistance times of the same against the fumes released in the event of a fire.

Another disadvantage no less important than the previous one? the one related to the choice of valid materials to be used to create a new and inventive alternative solution to the known ones, but, at the same time, fully valid in terms of quality/price ratio.

An additional disadvantage? consisting of the fact that difficult to make an insulating material that homogeneously combines the performance characteristics of known materials with minimized production cycle costs, n? ? It is easy to supply the building market with a photovoltaic panel that has a competitive quality/price ratio compared to the well-known metal sheet panels insulated with expanded polyurethane or other similar filling mixtures.

Therefore, the problems, which are not easy to solve today, are related to the optimization of said performance factors according to a minimization of the production cost of the insulated panels themselves, in order to provide the building market with a highly insulated panel that is both competitive and in terms of performance and manufacturing costs, as well as in the quality/price ratio for wholesale and retail. The object of the present invention is, therefore, to solve said problems and drawbacks of the prior art, by devising and producing an insulated panel for civil and industrial applications and the relative manufacturing process with a new insulating fluid mixture. Additional purpose of this system ? to use materials and components that, on equal terms? of constructional and functional characteristics, have a minimized cost, a possibly minimized environmental impact index, using possibly recyclable component elements over time.

Another object of the present invention ? identify a new insulating fluid mixture that minimizes the costs of the current fluid mixtures of the synthetic type in polyurethane foam, making them more environmentally friendly, through compound actions with the insertion of at least one innovative component element at minimized cost on equal terms? performance characteristics of the panel.

Another object of the present invention ? that of identifying a new production process, minimizing the construction costs of the panel equipped with the innovative insulating mixture, which is easily applicable on an industrial level using the machines and equipment already used in the production process. existing in the manufacture of panels insulated with synthetic materials, with minimal and non-onerous variations of the same procedural steps necessary for their mass production with a continuous cycle.

These aims are achieved by realizing an innovative and valid insulated panel for civil and industrial applications and the relative manufacturing process with an innovative insulating fluid mixture, according to what is claimed at the bottom of the present description and described below. Said purposes and the consequent advantages, as well as the characteristics of the invention according to the present invention will be more? clearly evident from the following detailed description of a preferred solution, given by way of non-limiting example with reference to the attached drawings, in which:

- Fig.1 ? a graphic diagram, in cross section, of an insulated panel P according to the present invention, basically consisting of a pair of containment means or plates L1-L2, in particular a first internal L1 and a second external L2, inside which an innovative insulating fluid mixture MF is inserted, which when producing the panel ? now hardened and solidified MS inside, as schematically represented in the same figure;

- Fig.2 ? a graphic diagram in cross section showing the same insulated panel P of Fig.1, now represented in exploded view in its component elements, namely said pair of containment means or sheet metal L1-L2, respectively internal L1 and external L2, and the? innovative fluid insulating mixture MF;

- Fig.3 ? a block diagram M showing the actions (A1-A2-A3) which are carried out for the preparation of the fluid mixture MF;

- Fig.4 ? a block diagram depicting the various phases (F1-F2-F3-F4-F5) of the production process F necessary to make the insulated panel P.

From the figures attached hereto below and showing a preferred but non-limiting solution of the inventive idea, an expert in the art can it is easy to deduce how the present invention brilliantly solves said limitations of the prior art, as it concerns an insulated panel P for civil and industrial applications and the related manufacturing process F with a new insulating fluid mixture MF (Fig.1).

The P panel? consisting of a pair of specifically spaced apart containment means L1-L2 of the same mixture MF, in a first preferred solution consisting of metal sheets L1-L2, constituting the internal and external surfaces of the insulated panel (Fig.2).

The P panel is characterized by the fact that ? insulated with an innovative component element consisting of a low-cost filling medium with high performance characteristics such as, in a preferred but non-limiting solution, expanded clay 5, intimately mixed with reactive elements such as the known polyol 1 and the known isocyanate 2 , together with a fluid expanding medium 3 and a further catalyst medium 4.

The expanded clay 5 is, therefore, inserted not only as a filling element minimizing the finished cost of the panel, but also as an element optimizing the performance characteristics of thermal insulation, lightness, fire resistance, soundproofing, stability? dimensional and mechanical resistance of the same panel P.

The P panel? It was designed to solve said problems of the prior art in order to basically find use as a structural means equipped with a valid insulating shield and minimized cost for both civil and industrial construction.

For these purposes, the insulated panel P ? was designed to be mass-produced, through a continuous cycle, in the shape of an approximately parallelepiped with dimensional characteristics of a modular type, in particular variable length and height H and depth? B modular and well defined.

Said dimensions have been designed in a modular way and will be defined precisely by said pair of pairs of containment means L1-L2, in the purely structural case, by plates L1-L2.

The pair of plates L1-L2 ? profiled up to a thickness in section T of sixteen tenths of a millimeter and will contain within them, during the construction of the same panel P, a fluid mixture MF, which at the end of the production process will be? fully hardened and then solidified MS.

Said panel P has the following modular dimensional characteristics: a variable length at will, a height H variable in a modular way up to one thousand five hundred millimeters and a depth of modularly variable B up to two hundred and fifty millimetres.

In case it is no longer the use of the insulating panel P as a structural means is fundamental, said pair of profiled plates L1-L2 can? be replaced with other pairs of containing means L1-L2 the mixture MF. Then ? It is possible to make sound-absorbing panels that have the same fluid mixture MF as the structural ones, but as containing means L1-L2 the pairs made up of:

- sheet metal/paper;

- card/card;

- sheet metal/laminates;

- laminates/laminates;

- sheet metal/fiberglass.

As regards said fluid mixture MF, it is specified that it ? made up of the following percentages by weight of constituent elements:

- polyol 1 ? inserted in the percentages by weight ranging from a minimum of seven percent to a maximum of thirty-two percent on the weight of the fluid mixture MF;

- the isocyanate 2 ? inserted in the percentages by weight ranging from a minimum of ten percent to a maximum of fifty percent on the weight of the fluid mixture MF;

- the blowing medium 3 ? included in the weight percentages ranging from a minimum of four per thousand to a maximum of eighteen per thousand on the weight of the fluid mixture MF;

- the half catalyst 4 ? included in the weight percentages ranging from a minimum of four per thousand to a maximum of sixteen per thousand on the weight of the fluid mixture MF;

- the inert medium 5, i.e. in the preferred but non-limiting case, the expanded clay 5, is inserted in percentages by weight ranging from a minimum of fifteen percent to a maximum of eighty percent on the weight of the fluid mixture MF.

The inert medium 5, if made up of expanded clay, is preferably inserted in the MF mixture as expanded clay of small particle size, ie included in the range from one to five millimetres, in order to optimize cos? its distribution within the same fluid mixture MF, as well as the homogenization of the latter, its binding power and its characteristics of mechanical resistance when hardened MS.

The mixing method or compound M of the component elements (1-5) the filling material of said insulated panel P, i.e. said polyol 1 and isocyanate 2, together with the fluid expanding medium 3, and with the further catalyst medium 4, in addition to the innovative filling medium of low cost and high performance characteristics, such as the preferred one consisting of expanded clay 5, it is further characterized by the fact that it is carried out by carrying out the following mixing actions (Fig.3):

- first action of compound A1: compound of the reactants, consisting of the polyol 1 and the isocyanate 2, forming the first component C1 of the filling material of the panel P;

- second action of mixture A2, to be activated simultaneously with said first action A1: mixture of the catalyst means 4 with the filling means 5, said elements forming the second component C2 of the filling material of the panel P;

- third compound action A3: final compound of the first C1 and second C2 component with the expanding fluid means 3, which leads to the expansion of the fluid mixture MF so? obtainable.

In any case, it must be kept in mind that during said mixing actions and immediately after the formation of the fluid mixture MF, checks must in any case be carried out both in the dosage of the component materials, before, during and after the mixing phase itself, and checks on the triggering of the expansion and growth reaction of the fluid mass MF, before the fluid mass MF itself undergoes, following the hardening reactions, its complete expansion and solidification, transforming itself into a filling material of the solid and compact panel MS.

The industrial manufacturing process F of the insulated panel P is instead divided into the following phases within a continuous production cycle (Fig.4):

- first production phase F1: preparation of the fluid mixture MF of the elements forming the internal volume of the panel P and consisting of the polyol 1, the isocyanate 2, a blowing fluid 3, a catalyst medium 4 and a filling medium 5;

- second production phase F2: automatic spreading of the fluid mixture MF within a pair of means L1-L2 containing the mixture MF, said spreading carried out in a continuous cycle at the same time as the pulling from the winding reels of the same means L1-L2 containing the mixture MF, through calenders suitable for their subsequent press-bending;

- third production phase F3: coupling with press-bending and creation of special ?V? 6 suitable for stiffening in correspondence with said recesses 6 of the containing means L1-L2 at a pre-established modular height H and at a pre-established modular thickness B, which are difficult to deform at the end of the press-bending phase, since said fluid mixture MF has completed its hardening in a solid and compact mass MS inside the oblong panel cos? forged;

- fourth production phase F4: cut to pre-established length, the latter function of the specific order or standard for mass production;

- fifth production phase F5: panel finishing P cos? product with quality control final and packaged in packages on platforms for subsequent handling and transport.

As ? Is it therefore possible to deduce from what has been described above and shown below the insulated panel for civil and industrial applications and the relative manufacturing process with a new insulating fluid mixture? new and inventive, as ? was suitably conceived and designed to solve said problems of the prior art, in order to produce a valid insulated panel for the final user, capable of completely replacing the known production of polyurethane insulating panels.

The performance characteristics obtainable from the creation of the new insulated panel allow its application in various civil and industrial application fields.

The present insulated panel has the further advantage of not producing a significant environmental impact at all, since it can be made up, in percentages by weight, of only metal and mainly inert components, both easily recyclable.

A further and undoubted advantage? constituted by the fact that this insulated panel can? be manufactured industrially, with a continuous cycle, in series, for a very wide range of civil and industrial applications, with geometries and dimensions such as to satisfy the most? various market needs.

The further advantages, no less important than the previous ones, derive from the further minimizable costs of the means containing the insulating fluid mixture, since the latter can consist not only of metal sheets, but also from said further wide and possible alternative choice of similar or different materials in type of application and mechanical strength.

The insulated panel according to the present invention is, therefore, validly usable for civil and industrial applications, as well as represents a valid and undoubted inventive idea and a new opportunity? for the current development of the post COVID-19 building economy.

? It is also evident that numerous adjustments, adaptations, additions, variations and replacements of elements with other functionally equivalent ones could be made to the embodiment previously described by way of non-limiting example, without departing from the scope of protection of the following claims.
