Description
Vynález se týká protipožární teplem zpěnitelné hmoty nanášené na skelnou stříž podloženou hliníkovou fólií na bázi vodního skla, vytvářející po tepelném zpracování nezorpustný křemičitan vápenatý a uhličitan sodný v poměru hmotnosti rovným dílem.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire-resistant heat-foamable material applied to a glass fiber backed with a water-glass-based aluminum foil, producing heat-insoluble calcium silicate and sodium carbonate in a weight ratio equal to that.
Dosud známá složení protipožární zpěnitelné hmoty nanášené na skelnou stříž podloženou hliníkovou fólií, jako na příklad složení hmoty uváděné v Ss. autorském osvědčení č. 231948, jsou silně hydroakopické a vyžadují značnou energetickou náročnost při jejich vytvrzování, zejména však jsou tyto protipožární zpěnitelné hmoty po nanesení na skelnou stříž s podloženou hliníkovou fólií a vytvrzení, kdy vzniká protipožární pěnotvorná deska, značně křehké. Při přepravě a montáži dochází k jejich odrolování a lámání.Already known compositions of fire-resistant foamable material deposited on an aluminum foil backed with an aluminum foil, such as the composition of the masses reported in Ss. Author's Certificate No. 231948, are strongly hydroacoptic and require considerable energy curing power, but in particular these fire-resistant foamable materials are extremely brittle after being applied to a glass fiber backed aluminum foil and cured to form a fire-resistant foam sheet. During transport and assembly, they break and break.
Uvedené nevýhody dosavadních protipožárních zpěnitelných hmot odstraňuje protipožární teplem zpěnitelná hmota podle tohoto vynálezu, která sestává hmotnostně se 190 dílů vodního skla sodného, 50 dílů sráženého uhličitanu vápenného a 15 až 20 dílů lupku.The aforementioned disadvantages of the prior art flame retardant compositions are eliminated by the fire-extinguishing composition of the present invention, which comprises 190 parts by weight of sodium waterglass, 50 parts by weight of calcium carbonate and 15 to 20 parts by weight of glass.
Protipožární teplem zpěnitelná hmota podle tohoto vynálezu snižuje, při jejím vytvrzování na nanesené skelné stříži s podloženou hliníkovou fólií, energetickou náročnost, zvyšuje elastičnost zhotovené desky a vyznačuje se minimální navlhavostí.The fire-retardant heat-curing composition of the present invention reduces, when cured on the deposited glass fiber backed with aluminum foil, the energy demand, increases the elasticity of the board and is characterized by minimal wetting.
Do průmyslového mixéru se dávkuje 190 dílů vodního skla sodného, 50 dílů sráženého uhličitanu vápenného a 15 až 20 dílů lupku. Poměr lupku je odvislý od požadované hustoty takto vzniklé kaěovité hmoty, která je dána pórovitostí použité skelné stříže na její snadné roztírání a nasáknutí hmoty do skelné stříže. Ha připravenou skelnou stříž, která je podložena hliníkovou fólií, se rozetře vzniklá kašovitá hmota, působením teploty 85 °C po dobu 30 minut se nanesená hmota mění na nerozpustný křemičitan vápenatý a uhličitan sodný, a to v poměru hmotnosti rovným dílem. Při působení vyšších teplot jak 200 °C na takto vzniklou protipožární desku, nastává zpěnitelnost nanesené hmoty, zajištující požadovanou požární odolnost.190 parts of sodium waterglass, 50 parts of precipitated calcium carbonate and 15 to 20 parts of leaflets are metered into the industrial mixer. The ratio of the dandruff depends on the required density of the resulting resulting mass, which is determined by the porosity of the glass fiber used to spread it and soak the mass into the glass fiber. The prepared glass staple, which is backed with an aluminum foil, is pulverized and the applied mass is converted to insoluble calcium silicate and sodium carbonate at a temperature of 85 ° C for 30 minutes in equal parts. When higher temperatures of 200 ° C are applied to the fire protection plate thus formed, the foamable foaming occurs, ensuring the required fire resistance.
