In this field, a construction material consisting of expanded polyvinyl chloride which is used particularly in the field of structural elements intended for the aeronautical sector is very common today. This traditional building material has the drawback that it is not easy to make and therefore has relatively high costs.
Il problema alla base della presente invenzione è quello di proporre un materiale da costruzione che sia producibile in modo più semplice rispetto a quelli tradizionali pur risultando almeno altrettanto leggero e ignifugo. The problem underlying the present invention is that of proposing a building material which can be manufactured in a simpler way than traditional ones while being at least as light and fireproof.
Compito principale del presente trovato consiste nel realizzare un materiale da costruzione ed un procedimento per produrlo che ponga soluzione a tale problema risolvendo i lamentati inconvenienti dei materiali da costruzione sopra descritti. The main aim of the present invention is to provide a construction material and a process for producing it which solves this problem by solving the aforementioned drawbacks of the construction materials described above.
Nell’ambito di tale compito è scopo del presente trovato proporre un materiale da costruzione che non generi esalazioni tossiche nel caso in cui venga in contatto con una fiamma viva. Within this aim, it is the aim of the present invention to propose a construction material that does not generate toxic fumes in the event that it comes into contact with a live flame.

Questo compito, nonché questi ed altri scopi che meglio appariranno nel seguito sono raggiunti da un materiale da costruzione e da un procedimento per produrlo secondo le rivendicazioni indipendenti allegate. This aim, as well as these and other objects which will become clearer in the following, are achieved by a construction material and by a process for producing it according to the attached independent claims.
Caratteristiche di dettaglio di un materiale da costruzione e di un procedimento per produrlo secondo il trovato sono riportate nelle rivendicazioni dipendenti. Detailed characteristics of a construction material and of a process for producing it according to the invention are reported in the dependent claims.
Ulteriori caratteristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita, ma non esclusiva, di un materiale da costruzione e di un procedimento per produrlo secondo il trovato. Further characteristics and advantages of the invention will become clearer from the description of a preferred, but not exclusive, embodiment of a construction material and of a process for producing it according to the invention.
Il procedimento per produrre un materiale da costruzione secondo la presente invenzione presenta una particolare peculiarità nel fatto di comprendere: - una fase di formare un corpo in schiuma fenolica; The process for producing a construction material according to the present invention has a particular peculiarity in that it comprises: - a step of forming a body in phenolic foam;
- una fase di irrorare la superficie di detto corpo mediante una soluzione acquosa di resina acrilica. - a step of spraying the surface of said body by means of an aqueous solution of acrylic resin.
Vantaggiosamente il procedimento secondo il trovato prevede una fase di asciugatura nell’ambito della quale evapora la parte di solvente della suddetta soluzione e rimane depositata, sulla superficie di detto corpo, la parte di soluto di detta soluzione acquosa. Advantageously, the method according to the invention provides for a drying step in which the solvent part of the aforementioned solution evaporates and the solute part of said aqueous solution remains deposited on the surface of said body.
Detta fase di irrorare preferibilmente prevede di spruzzare detta soluzione acquosa su detta superficie. Tale procedimento consente di consolidare la superficie di un corpo in schiuma fenilica e permettere così l’adesione di ulteriori materiali a tale superficie. In dettaglio, il procedimento secondo il trovato prevede, in sequenza: una fase di formatura di un blocco di schiuma fenolica, una fase di taglio da detto blocco di un corpo di forma predefinita, una fase di pulitura della superficie di detto corpo, una fase di calibratura di detto corpo, una fase di spruzzaggio di detto corpo con detta soluzione acquosa ed una fase di asciugatura. Said spraying step preferably provides for spraying said aqueous solution on said surface. This procedure allows to consolidate the surface of a phenyl foam body and thus allow the adhesion of further materials to that surface. In detail, the method according to the invention provides, in sequence: a step of forming a block of phenolic foam, a step of cutting from said block of a body having a predefined shape, a step of cleaning the surface of said body, a step for calibrating said body, a step of spraying said body with said aqueous solution and a drying step.
