TITOLO: FORMULAZIONE COMPRENDENTE UNA COMBINAZIONE DI PIGMENTI TITLE: FORMULATION INCLUDING A COMBINATION OF PIGMENTS
Descrizione Description
Campo dell?invenzione Field of invention
La presente invenzione riguarda una formulazione comprendente pigmenti nonch? un rivestimento contenente detta formulazione per applicazione su un opportuno substrato. La presente invenzione riguarda inoltre parti di automobili o moto sulle quali ? applicato detto rivestimento. The present invention concerns a formulation comprising pigments as well as a coating containing said formulation for application on a suitable substrate. The present invention also concerns parts of automobiles or motorbikes on which? applied said coating.
Stato dell?arte State of art
La scelta della vernice nel processo di verniciatura dei veicoli, quali automobili e moto, ? una questione delicata e per nulla trascurabile. The choice of paint in the painting process of vehicles, such as cars and motorcycles, is ? a delicate and not at all negligible issue.
Alcuni pigmenti lamentano infatti una tendenza a degradare se sottoposti a raggi UV, oppure una inferiore solidit? alla luce e agli agenti atmosferici, altri ancora accusano una inferiore stabilit? al colore con l?aumentare delle temperature, con conseguente decolorazione, sbiadimento o scrostatura della vernice nel tempo. In fact, some pigments have a tendency to degrade if subjected to UV rays, or a lower solidity? to light and atmospheric agents, others still suffer from inferior stability? to the color as temperatures increase, resulting in discoloration, fading or peeling of the paint over time.
Un altro fattore che spesso comporta l?alterazione della tonalit? della vernice nel tempo va ricercato nella deposizione sulle superfici verniciate di polveri e micropolveri derivanti prevalentemente dall?usura dei freni, causata dallo sfregamento delle pastiglie contro i dischi. La formazione di tali polveri ? un problema tuttora fortemente sentito, sebbene numerosi sforzi siano stati fatti per tentare di ridurre la loro emissione e per catturarle prima che esse si possano depositare sulle superfici. Another factor that often involves the alteration of the shade? of the paint over time is to be found in the deposition on the painted surfaces of dust and micro-dust mainly deriving from the wear of the brakes, caused by the rubbing of the pads against the discs. The formation of such dust? a problem that is still strongly felt, although numerous efforts have been made to try to reduce their emission and to capture them before they can settle on surfaces.
Il problema dell?alterazione della tonalit? della vernice nel tempo, specialmente di alcune parti specifiche quali l?impianto frenante, in particolare le pinze freno e i dischi per freni a disco, ? maggiormente percepito nei veicoli ad alte prestazioni, per esempio auto di alta gamma o moto per competizioni, in cui l?impianto frenante ? sottoposto ad un uso intenso con generazione di temperature molto elevate e ingenti quantit? di polveri a causa della frizione tra il disco e la pastiglia. The problem of tone alteration? of the paint over time, especially of some specific parts such as the braking system, in particular the brake calipers and disc brake discs, ? more perceived in high-performance vehicles, for example high-end cars or motorbikes for competitions, in which the braking system is subjected to intense use with generation of very high temperatures and large quantities? of dust due to the friction between the disc and the pad.
Pertanto, il problema che sta alla base della presente invenzione ? quello di risolvere il problema sopra esposto, vale a dire mettere a disposizione una opportuna miscela di pigmenti nonch? un opportuno rivestimento il cui colore resti sostanzialmente immutato nel tempo, specialmente quando applicato a componenti specifici di auto e moto, e quindi anche dopo migliaia di chilometri percorsi. Therefore, the problem underlying the present invention is? is to solve the above problem, i.e. to make available an appropriate mixture of pigments as well as? an appropriate coating whose color remains substantially unchanged over time, especially when applied to specific components of cars and motorbikes, and therefore even after thousands of kilometers travelled.
Sommario dell?invenzione Summary of the invention
Il problema sopra enunciato ? risolto da una formulazione, da un rivestimento comprendente detta formulazione, nonch? da componenti di automobili e moto, come delineati nelle annesse rivendicazioni, le cui definizioni formano parte integrante della presente descrizione.
