DESCRIZIONE DESCRIPTION
del brevetto per invenzione industriale dal titolo: “COMPOSIZIONE DI RIVESTIMENTO CHE ASSORBE INFRAROSSI” of the patent for industrial invention entitled: "COATING COMPOSITION THAT ABSORBES INFRARED"
La presente invenzione è relativa ad una composizione di rivestimento in grado di assorbire radiazioni nello spettro degli infrarossi. The present invention relates to a coating composition capable of absorbing radiation in the infrared spectrum.
E’ noto quanto le prestazioni dei pneumatici possano influenzare l’esito di una gara automobilistica. Nelle corse di Formula 1, in particolare, è necessario che le gomme abbiano una temperatura compresa in un ristretto intervallo e che tale temperatura sia raggiunta in modo più rapido possibile in modo da ottimizzarne le prestazioni durante la competizione. It is well known how much tire performance can influence the outcome of a car race. In Formula 1 racing, in particular, it is necessary that the tires have a temperature included in a narrow range and that this temperature is reached as quickly as possible in order to optimize their performance during the competition.
A tale scopo è noto utilizzare termocoperte per tenere gli pneumatici in temperatura oppure applicare vernici con pigmento nero e superficie opaca sul cerchione dello pneumatico. For this purpose it is known to use electric blankets to keep the tires at temperature or to apply paints with black pigment and an opaque surface on the tire rim.
Per scaldare le gomme è importante, se non basilare, che il riscaldamento sia ottenuto con materiali che non abbiano uno spessore superficiale eccessivo per consentire lo scambio termico rapido tra lo pneumatico e l’esterno ed evitare il deterioramento dello pneumatico. To warm the tires it is important, if not basic, that the heating is obtained with materials that do not have an excessive surface thickness to allow rapid heat exchange between the tire and the outside and avoid tire deterioration.
Si è tuttavia sempre alla ricerca di nuovi metodi per aumentare la temperatura delle gomme senza tuttavia aumentare il peso della vettura. However, new methods are always being sought to increase the temperature of the tires without increasing the weight of the car.
Lo scopo della presente invenzione è pertanto quello di fornire un nuovo metodo per consentire il riscaldamento delle gomme senza aumentare il peso della vettura sulla quale sono montate. The object of the present invention is therefore to provide a new method for allowing the tires to warm up without increasing the weight of the car on which they are mounted.
Tale scopo è raggiunto dalla presente invenzione, in quanto relativa ad una composizione di rivestimento in grado di assorbire radiazioni nello spettro degli infrarossi ed in tal modo riducendo i tempi di riscaldamento secondo la rivendicazione 1 senza l’ausilio di pigmenti neri e di superfici opache. This object is achieved by the present invention, as it relates to a coating composition capable of absorbing radiations in the infrared spectrum and thus reducing the heating times according to claim 1 without the aid of black pigments and opaque surfaces.
La presente invenzione verrà ora descritta in modo dettagliato con riferimento alle figure dei disegni annessi, in cui: The present invention will now be described in detail with reference to the figures of the annexed drawings, in which:
- la Figura 1 illustra lo spettro di assorbimento di una composizione di rivestimento secondo la presente invenzione. Figure 1 illustrates the absorption spectrum of a coating composition according to the present invention.
In particolare, secondo un primo aspetto dell’invenzione, viene fornita una composizione di rivestimento comprendente: In particular, according to a first aspect of the invention, a coating composition is provided comprising:
20-40% in peso di silicio; 20-40% by weight of silicon;
3-7% in peso di ossidi di ferro; 3-7% by weight of iron oxides;
sul peso totale della composizione. on the total weight of the composition.
Più preferibilmente, la composizione di rivestimento comprende: More preferably, the coating composition comprises:
3-10% in peso di silani; 3-10% by weight of silanes;
3-10 % in peso di silossani; 3-10% by weight of siloxanes;
20-40% in peso di silicio; 20-40% by weight of silicon;
3-7% in peso di ossidi di ferro; 3-7% by weight of iron oxides;
sul peso totale della composizione. on the total weight of the composition.
Ancora più preferibilmente, la composizione di rivestimento comprende: Even more preferably, the coating composition comprises:
3-5% in peso di silani; 3-5% by weight of silanes;
3-5% in peso di silossani; 3-5% by weight of siloxanes;
30-40% in peso di silicio; 30-40% by weight of silicon;
3-5% in peso di ossidi di ferro 3-5% by weight of iron oxides
sul peso totale della composizione. on the total weight of the composition.
Vantaggiosamente la composizione secondo la presente invenzione può essere applicata come rivestimento sulla superficie interna dei cerchioni. Essa è in grado di catturare il calore prodotto sotto forma di radiazioni nello spettro degli infrarossi dal sistema frenante e quindi aumentare rapidamente la temperatura degli pneumatici. La composizione dell’invenzione trova inoltre applicazione come rivestimento delle caldaie o come ausilio alla ricezione degli infrarossi nei punti dove serve la concentrazione di calore, permettendo di non disperdere gli infrarossi in altre direzioni all'interno della parte comburente della caldaia. Advantageously, the composition according to the present invention can be applied as a coating on the inner surface of the rims. It is capable of capturing the heat produced in the form of infrared radiation from the brake system and thus rapidly increasing the temperature of the tires. The composition of the invention also finds application as a coating of boilers or as an aid to the reception of infrared at the points where the concentration of heat is needed, allowing the infrared not to be dispersed in other directions within the combustion part of the boiler.
Inoltre, la composizione dell’invenzione è applicabile in spessori molto ridotti consentendo quindi facilmente il trasferimento di calore. Infine, la composizione conferisce alla superficie a cui è applicata proprietà anti-adesive, limitando quindi il deposito di residui di olio, idrocarburi incombusti, e sporco mantenendo inalterate le sue proprietà nel tempo. Furthermore, the composition of the invention can be applied in very reduced thicknesses, thus easily allowing heat transfer. Finally, the composition gives the surface to which it is applied anti-adhesive properties, thus limiting the deposit of oil residues, unburnt hydrocarbons, and dirt while maintaining its properties unchanged over time.
La composizione dell’invenzione può inoltre comprendere una miscela di ossidi di stagno e ossidi di antimonio in una quantità compresa tra 1 e 5 % in peso sul peso totale della composizione. The composition of the invention can also comprise a mixture of tin oxides and antimony oxides in an amount ranging from 1 to 5% by weight of the total weight of the composition.
Una composizione secondo l’invenzione viene preparata miscelando silani, silicio e silossani per 30 minuti con ultrasuoni. Viene poi aggiunto un lubrificante e gli ossidi di metallo miscelando per altri 60 minuti con interruzione ogni 10 minuti per evitare l’eccessivo riscaldamento della miscela. A composition according to the invention is prepared by mixing silanes, silicon and siloxanes for 30 minutes with ultrasound. A lubricant and metal oxides are then added, mixing for another 60 minutes with interruption every 10 minutes to avoid excessive heating of the mixture.
La composizione così ottenuta è stabile a intervalli di temperatura compresi tra -60°C e 650°C. Essa può essere applicata alla superficie da trattare ad esempio mediante spruzzamento elettrostatico, ottenendo strati di uno spessore compreso tra 0,2 e 20 micron The composition thus obtained is stable at temperature ranges between -60 ° C and 650 ° C. It can be applied to the surface to be treated, for example by electrostatic spraying, obtaining layers with a thickness of between 0.2 and 20 microns.
Ulteriori caratteristiche della presente invenzione risulteranno dalla descrizione che segue di alcuni esempi meramente illustrativi e non limitativi. Further characteristics of the present invention will emerge from the following description of some merely illustrative and non-limiting examples.
