Abstract

Marking strips, provided on the lower side with an adhesive primer, are attached to a road surface by laying the strip over a flame which also contacts the road surface in which the flame both dehydrates the surface and melts the adhesive primer, the two actions being controllable by orientation of the flat cross-section of the flame, the shape of the flame being created by the pressure leaving the nozzle.

DESCRIZIONEDESCRIPTION Le strisce segnaletiche, orizzontali prefabbricate, che come è noto sono importanti per la sicurezza della circolazione stradale, vengono di solito attualmente posate previo trattamento della superficie stradale con uno strato di fondo, ossia di un «primer».The prefabricated horizontal marking strips, which as is well known are important for road traffic safety, are currently usually laid after treating the road surface with a base layer, i.e. a "primer". Esso viene di solito spruzzato sul manto stradale senza una particolare preparazione dello stesso, e non appena il solvente è evaporato, il primer è pronto per ricevere la striscia segnaletica.It is usually sprayed onto the road surface without any special preparation of the same, and as soon as the solvent has evaporated, the primer is ready to receive the marking strip. Il richiedente è titolare di numerosi brevetti nel campo della segnaletica stradale orizzontale, tra i quali molti si riferiscono per l'appunto ai metodi per l'adesivazione della striscia alla superficie stradale, e alle relative apparecchiature.The applicant owns numerous patents in the field of horizontal road signs, many of which refer precisely to the methods for adhering the strip to the road surface, and to the related equipment. Si possono citare in proposito i brevetti concessi negli Stati Uniti d'America No. 3 844 669, 3 902 939, 3 964 835 e 4 102 718.In this regard, the patents granted in the United States of America No. 3 844 669, 3 902 939, 3 964 835 and 4 102 718 can be mentioned. Attualmente si presenta sempre più pressante la richiesta di tecnologie che garantiscono alta efficienza e lunga vita alla segnaletica, sulle superfici stradali le più varie, sia quale tipo che quale ubicazione, e pose più rapide.Currently there is an increasingly pressing demand for technologies that guarantee high efficiency and long life to signs, on the most varied road surfaces, both in terms of type and location, and more rapid installation. Nonostante i progressi via via compiuti, anche grazie, come detto, alle invenzioni del richiedente, non si può dire che il problema sia stato risolto in modo definitivo.Despite the progress gradually made, also thanks, as mentioned, to the applicant's inventions, it cannot be said that the problem has been resolved definitively. La presente invenzione intende dare una adeguata risposta alle esigenze sopra accennate, e costituisce una innovazione molto importante nei metodi per depositare e far aderire una striscia segnaletica alla superficie stradale.The present invention intends to give an adequate response to the above mentioned requirements, and constitutes a very important innovation in the methods for depositing and adhering a marking strip to the road surface. Il primer viene assorbito dalla superficie del manto in notevole quantitativo e ha quali proprietà principali prima di tutto quella di essere idrorepellente, per resistere all'attacco dell'acqua dal fondo del manto stradale, in secondo luogo la proprietà di essere compatibile con il retro della striscia segnaletica, in terzo luogo la proprietà di resistere alla temperatura del manto, di solito almeno a 70°C. Infine il primer, dati i quantitativi assorbiti, deve avere un costo di materie prime molto basso.The primer is absorbed by the surface of the surface in a considerable quantity and its main properties are first of all that of being water repellent, to resist the attack of water from the bottom of the road surface, secondly the property of being compatible with the back of the warning strip, thirdly the property of resisting the temperature of the surface, usually at least 70°C. Finally, the primer, given the quantities absorbed, must have a very low cost of raw materials. Inoltre il primer, di per se stesso idrorepellente, per poter penetrare nei pori della superficie stradale, deve avere una viscosità molto bassa, e una veloce assorbibilità da parte del manto.Furthermore, the primer, in itself water-repellent, in order to penetrate the pores of the road surface, must have a very low viscosity and be quickly absorbed by the surface. Il problema viene di solito risolto mediante un'aggiunta di solventi, ma si rende ancor più evidente un difetto collaterale, che è il tempo di posa dovuto alla presenza del solvente.The problem is usually solved by the addition of solvents, but a collateral defect becomes even more evident, which is the shutter speed due to the presence of the solvent. Tutti questi aspetti tecnici delicati stanno forzando gli utilizzatori a posare senza l'impiego di primer, e con risultati parecchie volte negativi.All these delicate technical aspects are forcing users to lay without the use of primer, and with often negative results. La presente invenzione è inerente a una conoscenza approfondita della dinamica del processo di attacco della striscia.The present invention relates to an in-depth knowledge of the dynamics of the strip etching process. Un fenomeno che rende difficile la soluzione del problema, soprattutto per quanto riguarda la lunga vita della striscia, è quello che, essendo la superficie del manto stradale fitta di pori e di piccoli canali, in essi staziona abitualmente dell'acqua: fenomeni complessi, collegati con la tensione superficiale, e cioè fenomeni di capillarità, e altri di più semplice comprensione dovuti al gelo, provocano, a causa della presenza di tale umidità, una pressione dal basso sulla striscia segnaletica.A phenomenon that makes the solution of the problem difficult, especially as regards the long life of the strip, is that which, being the surface of the road surface full of pores and small channels, usually contains water: complex phenomena, connected with surface tension, i.e. phenomena of capillarity, and other simpler understanding due to frost, cause, due to the presence of this humidity, a pressure from below on the marking strip. Questa umidità non favorisce l'assorbimento del primer da parte della superficie del manto; se questo primer contiene componenti idrofili volatili, questi, evaporando, creano dei vuoti e diminuiscono il potere idrofobico.This humidity does not favor the absorption of the primer by the surface of the coat; if this primer contains volatile hydrophilic components, these, by evaporating, create voids and decrease the hydrophobic power. Se la striscia viene posata senza primer, fra l'autoadesivo e il manto si forma una zona di canali e pori pericolosamente esposta all'aggressione delle intemperie.If the strip is laid without primer, an area of channels and pores forms between the self-adhesive and the covering, dangerously exposed to the elements. Il problema, secondo l'invenzione, è solo risolvibile se si creano tanto per l'adesivo della striscia che per la superficie stradale contemporaneamente la condizione optimum per il processo di attacco.The problem, according to the invention, can only be solved if the optimum conditions for the bonding process are created both for the adhesive of the strip and for the road surface at the same time. L'autoadesivo deve trovarsi alla temperatura la più alta possibile, alla quale corrisponde la massima fluidità; la superficie del manto deve avere subito un processo di essiccazione totale, e trovarsi in fase aspirante-, in tali condizioni contemporanee la superficie viene messa a contatto con il primer fuso che viene aspirato. I pori e i canali vengono così sigillati, dando così le massime garanzie di attacco nel tempo.The self-adhesive must be at the highest possible temperature, which corresponds to the maximum fluidity; the surface of the covering must have undergone a total drying process, and be in the suction phase; in these conditions at the same time the surface is put in contact with the molten primer which is sucked up. The pores and channels are thus sealed, thus giving the maximum guarantees of attack over time. La presente invenzione prevede quindi l'impiego di una striscia segnaletica munita sulla sua faccia inferiore di un abbondante film di un composto autoadesivo, atto, allorché viene fuso ad alta temperatura, ad adempiere per l'appunto la funzione di sigillante e contemporaneamente quella di primer. La posa viene attuata utilizzando una fiamma che investe contemporaneamente sia il manto stradale che il film di autoadesivo; a titolo esemplificativo ma non tassativo, circa un terzo della fiamma investe il film di autoadesivo, e due terzi investono il manto stradale.The present invention therefore provides for the use of a warning strip provided on its lower face with an abundant film of a self-adhesive compound, suitable, when melted at high temperature, to fulfill precisely the function of sealant and simultaneously that of primer . Laying is carried out using a flame which invests both the road surface and the self-adhesive film at the same time; by way of non-exhaustive example, about one third of the flame invests the self-adhesive film, and two thirds invest the road surface.
