Description
L'invenzione ha per oggetto un adesivo a base di bitume, gomma stirene-butadienestirene, resine conferenti appiccicosità e cariche, in particolare per impiego come componente adesivo a pressione a freddo di guaine impermeabilizzanti per tetti, in cui l'adesivo è coperto con una pellicola protettiva rimuovibile o come rivestimento termoadesivo per guaine da applicare a caldo (guaine saldabili). Inoltre, l'invenzione ha per oggetto una guaina impermeabilizzante adesiva a pressione per tetti, che è dotata di uno strato di adesivo a base di bitume, gomma stirenebutadienestirene, resine conferenti appiccicosità e cariche, coperto con una pellicola protettiva rimuovibile. . The invention relates to an adhesive based on bitumen, styrene-butadienestyrene rubber, resins conferring stickiness and fillers, in particular for use as a cold pressure adhesive component of waterproofing sheaths for roofs, in which the adhesive is covered with a removable protective film or as a thermo-adhesive coating for heat-applied sheaths (weldable sheaths). Furthermore, the invention relates to a pressure adhesive waterproofing sheath for roofs, which is equipped with a layer of adhesive based on bitumen, styrenebutadienestyrene rubber, resins giving tackiness and fillers, covered with a removable protective film. .
Per l'impermeabilizzazione di tetti o coperture, s'impiegano in ampia misura guaine impermeabilizzanti conferenti appiccicosità a pressione. Per motivi di protezione dagli incendi, tali guaine impermeabilizzanti devono essere ritardanti di fiamma. Nell'industria, a tale scopo s'impiegano comunemente agenti ignifuganti che possono essere aggiunti al materiale plastico impiegato per la fabbricazione della guaina impermeabilizzante, e per mezzo dei quali è possibile conseguire una sufficiente resistenza alla fiamma' senza svantaggiosa variazione delle caratteristiche della guaina sigillante, Purtroppo, tuttavia, fino ad oggi non è stato possibile trovare alcun agente ritardante di fiamma che sia adatto per incorporazione in un adesivo a base di bitume, gomma stirene-butadienestirene, resine conferenti appiccicosità e cariche, per cui il trattamento ritardante di fiamma della guaina impermeabilizzante da sola non apporta vantaggi. For the waterproofing of roofs or coverings, waterproofing sheaths are used to a large extent, conferring stickiness under pressure. For fire protection reasons, these waterproofing membranes must be flame retardant. In industry, fireproofing agents are commonly used for this purpose, which can be added to the plastic material used for the manufacture of the waterproofing sheath, and by means of which it is possible to achieve sufficient flame resistance without disadvantageous changes in the characteristics of the sealing sheath. Unfortunately, however, to date it has not been possible to find any flame retardant agent that is suitable for incorporation into an adhesive based on bitumen, styrene-butadienestyrene rubber, tack-giving resins and fillers, so the flame retardant treatment of the waterproofing sheath alone does not bring benefits.
Quali agenti ignifuganti ovvero ritardanti di fiamma per materiali plastici s'impiegano attualmente in particolare fosfati d'ammonio e composti alogenati del fosforo come, ad esempio, tri(2,3-dibromopropil)fosfato . Tuttavia, nel caso degli adesivi, gli agenti ritardanti di fiamma, o ignifuganti, noti presentano lo svantaggio che la forza di adesione viene indesiderabilmente considerevolmente ridotta dall'aggiunta dell'agente ignifugante. Currently, ammonium phosphates and halogenated phosphorus compounds such as, for example, tri (2,3-dibromopropyl) phosphate are used as flame retardants or flame retardants for plastics. However, in the case of adhesives, the known flame retardants or flame retardants have the disadvantage that the adhesion force is undesirably considerably reduced by the addition of the flame retardant agent.
Scopo dell'invenzione è risolvere il problema di sviluppare un adesivo del tipo citato nell'introduzione che, nonostante le sue caratteristiche ritardanti di fiamma presenti una forza di adesione che sia il più possibile buona. Inoltre, si voleva provvedere una guaina impermeabilizzante adesiva a pressione a freddo per tetti, in cui anche lo strato adesivo avesse caratteristiche ritardanti di fiamma. The object of the invention is to solve the problem of developing an adhesive of the type mentioned in the introduction which, despite its flame retardant characteristics, has an adhesion strength that is as good as possible. In addition, it was intended to provide a cold pressure adhesive waterproofing sheath for roofs, in which the adhesive layer also had flame retardant characteristics.
Il problema citato per primo viene risolto secondo l'invenzione per mezzo di un'addittivazione di agente ignifugante (agente ritardante di fiamma) di da circa il 15 al 25% di polistirene bromurato oppure per mezzo dell'addizione di dal 5 al 15% di fosforo rosso, stabilizzato e micronizzato nella forma di un concentrato al 5% in una cera estere parzialmente saponificata. The problem mentioned first is solved according to the invention by means of an additive of fireproofing agent (flame retardant agent) of from about 15 to 25% of brominated polystyrene or by means of the addition of from 5 to 15% of red phosphorus, stabilized and micronized in the form of a 5% concentrate in a partially saponified ester wax.
Sorprendentemente si è osservato che, nonostante la relativamente grande quantità della addittivazione, la forza di adesione dell'adesivo, a paragone di uno stesso adesivo senza tale addittivazione diminuisce soltanto da 15,5 N/cm a 13,9 N. La stabilità al calore di un tale adesivo non viene attirata dall'addittivazione. È stato possibile determinare che, nel caso di una guaina impermeabilizzante per tetti con uno strato adesivo formato dall'adesivo secondo l'invenzione tenuta appesa verticalmente, questo strato adesivo non scorre {non forma insaccatura) neanche dopo 24 ore alla temperatura di 80°C. Surprisingly it was observed that, despite the relatively large amount of additivation, the bond strength of the adhesive, compared to the same adhesive without this additivation, only decreases from 15.5 N / cm to 13.9 N. The heat stability of such an adhesive is not attracted by additives. It was possible to determine that, in the case of a roof waterproofing membrane with an adhesive layer formed by the adhesive according to the invention held vertically, this adhesive layer does not flow (does not form bagging) even after 24 hours at a temperature of 80 ° C .
Per lo studio delle caratteristiche di resistenza alla fiamma, due strisce larghe 20 irai e lunghe 200 mm, di una guaina impermeabilizzante per tetti, sono state dotate in un caso di uno strato adesivo senza l'agente ritardante di fiamma, e nell'altro di uno strato adesivo con l'agente ritardante di fiamma, e in ciascun caso, la striscia è stata appesa verticalmente in corrispondenza di un'estremità, e successivamente in corrispondenza dell'estremità inferiore è stata accesa per mezzo di una fiamma. In tale contesto, la striscia.con lo strato adesivo senza ritardante di fiamma è bruciata completamente, mentre la striscia con lo strato adesivo contenente il ritardante di fiamma si è spenta da sola dopo un tempo di combustione di 50 secondi e un percorso della fiamma di 100 miti. For the study of the characteristics of flame resistance, two strips 20 irai wide and 200 mm long, of a waterproofing sheath for roofs, were equipped in one case with an adhesive layer without the flame retardant agent, and in the other with an adhesive layer with the flame retardant agent, and in each case, the strip was hung vertically at one end, and subsequently at the lower end it was ignited by means of a flame. In this context, the strip with the adhesive layer without flame retardant burned out completely, while the strip with the adhesive layer containing the flame retardant extinguished by itself after a burning time of 50 seconds and a flame path of 100 myths.
Polistirene bromurato, o fosforo rosso macinato a polvere fine {= micronizzato) possono essere lavorati con estrema facilità e possono essere incorporati, quale carica in forma di polvere, con semplicità, nel bitume, insieme con gli altri materiali. Perciò, l'incorporazione dell'agente ritardante di fiamma non presenta alcun problema. Il polistirene bromurato è disponibile presso la società Pyro-CHEK, Ferro-Corporation, Ferro Chemical Group, Bedford/Ohio. Il fosforo rosso è disponibile ^presso la società Clariant, D-50354 Hiirth, con il nome commerciale "Hostaflam RP 683". Brominated polystyrene, or red phosphorus ground with a fine powder {= micronized) can be processed very easily and can be incorporated, as a filler in the form of powder, with simplicity, in the bitumen, together with the other materials. Therefore, the incorporation of the flame retardant agent does not present any problems. Brominated polystyrene is available from Pyro-CHEK, Ferro-Corporation, Ferro Chemical Group, Bedford / Ohio. The red phosphorus is available ^ from the Clariant company, D-50354 Hiirth, under the trade name "Hostaflam RP 683".
Il problema citato per secondo, e precisamente provvedere una guaina impermeabilizzante adesiva a pressione a :freddo e ritardante di fiamma viene risolto secondo l'invenzione con ciò che lo strato adesivo contiene da circa il 15 al 25 di polistirene bromurato o dal 5 al 15% di fosforo rosso, stabilizzato e micronizzato nella forma di un concentrato al 65% in una cera estere parzialmente. saponificata. Una tale guaina impermeabilizzante è ignifugata nel suo complesso, dunque compreso il suo strato adesivo, e in confronto alle guaine impermeabilizzanti senza caratteristiche ritardanti di fiamma presenta una forza di adesione soltanto leggermente ridotta. The problem mentioned second, namely providing a cold and flame retardant pressure adhesive waterproofing sheath, is solved according to the invention with the fact that the adhesive layer contains from about 15 to 25 of brominated polystyrene or from 5 to 15% of red phosphorus, stabilized and micronized in the form of a 65% concentrate in a partially ester wax. saponified. Such a waterproofing sheath is fireproof as a whole, therefore including its adhesive layer, and compared to waterproofing sheaths without flame retardant characteristics it has only a slightly reduced adhesion force.
Le proposte precedentemente citate, di un trattamento ritardante di fiamma di guaine impermeabilizzanti per tetti valgono anche per un rivestimento di termoadesivo di guaine da applicare a caldo. Stato della tecniche è qui l'attivazione della colla con una fiamma a gas aperta, nel quale contesto il rischio di incendio è corrispondentemente alto. Per mezzo dell'aggiunta secondo l'invenzione di polistirene bromurato, oppure di fosforo rosso nella massa di rivestimento di termoadesivo, è possibile tuttavia conseguire anche in questo caso un sufficiente effetto di ignifugazione (effetto di ritardo di fiamma). The aforementioned proposals for a flame retardant treatment of waterproofing sheaths for roofs also apply to a thermo-adhesive coating of sheaths to be applied by heat. State of the art here is the activation of the glue with an open gas flame, in which context the fire risk is correspondingly high. However, by adding brominated polystyrene or red phosphorus to the thermoadhesive coating mass according to the invention, it is also possible in this case to achieve a sufficient flame retardant effect (flame retardant effect).
