Description
Vynález oe týká vodovzdorného a pěnotvoraého prostředku proti ohňi s regulovatelnou dobou tuhnutí.FIELD OF THE INVENTION The present invention relates to a water-resistant and foamable flame retardant composition with controllable setting time.
Běžná pěnotvorná prostředky proti ohni, jež vykazují pěnotvomost zhruba do 30 aa výěky, mají nedosfeMt&ou odolnost ve vlhkém prostředí, kde absorbují vlhkost, aokvají až stékají, a tia ztrácejí svoji funkci a účinnost. Jiné pěnotvomé prostředky se zvýšenou odolnosti proti vlhkosti vykazují malou pěnotvomost, ooa 10 až 15 an, takže zábrana vroti požáru je méně účinná. Je známý pěnotvomý prostředek proti ohni se zvýženou odolností proti vlhkosti složený A látek organického a anorganického původu rozpuštěných a dispergovaných ve vodě, jehož konzistenci lze upravit podle potřeby pro postřik nebo nátěr apod. Pěna, která oe po styku β vysokou teplotou nebo ohně* na předmětu opatřeným prostředkem vytvoří, dosahuje výěky kolem 30 až 50 mm podle mocnosti nanesená vrstvy.Conventional flame-retardant foams having a foaming power of up to about 30 a and above have a non-phosphorus resistance in a humid environment where they absorb moisture, leak to run down, and tia lose their function and effectiveness. Other foaming agents with increased moisture resistance exhibit low foaming properties of 10 to 15 an, so that the fire barrier is less effective. There is known a foam-forming fire-fighting composition with increased moisture resistance composed of A substances of organic and inorganic origin dissolved and dispersed in water, the consistency of which can be adjusted as desired for spraying or coating etc. Foam which after contact with β high temperature or fire * provided with the means, it reaches a height of about 30 to 50 mm, depending on the thickness of the deposited layer.
Řadu pěnivých retardérů rozšiřuje, nedostatky existujících odstraňuje a novou vlastnost při použití prostředku v regulovatelnost doby tuhnutí přináší vodovzdorný a pěnotvorný prostředek proti ohni s regulovatelnou dobou tuhnutí podle vynálezu, jehož podstata spočívá v tom, žo so okládá ze smšoi 4,4 hmotnostních dílů dlhydregenfosforečnanu amonného, 2,5 až'4,4 hmotnostních dílů dusičnanu amonného, 30 už 50 hmotnostních dílů doxtrinu, 14 až 60 hmotnostních dílů modifikátora, např. aoSovinoformaldehydová prysky216 381It expands the range of foaming retarders, eliminates the shortcomings of existing ones, and provides a new property in the use of the solidification time control agent by providing a water-resistant and foamable flame retardant composition according to the invention consisting of a mixture of 4.4 parts by weight 2.5 to 4.4 parts by weight of ammonium nitrate, 30 to 50 parts by weight of doxtrin, 14 to 60 parts by weight of a modifier, such as α-formoformaldehyde resin.
216 381 řiče, melaminoformaldehydové pryskyřice, 22 až 35 hmotnostních dílů vody a 0,12 až 1,2 hmotnostních dílů katalyzátoru, např. kyseliny fosforečné.216,381 resins, melamine-formaldehyde resins, 22 to 35 parts by weight of water and 0.12 to 1.2 parts by weight of a catalyst such as phosphoric acid.
Hlavní výhody prostředku podle vynálezu ae jeví v jehe vodovzdornosti, která umožňuje použití prostředku i do interiérů.,, kde dochází občas ke kondenzaci výparů. Nátěr prostředku je možno upravit povrchově disperzními a roztokovými barvami podle požadavku uživatele, Dalěí podstatná výhoda ss projevuje v regulovatelnosti doby tuhnutí-tvrdnutí prostředku pomocí změny pH směsi katalyzátorem, a to podle potřeby uživatele. Tím jsou zvýhodněny věechny technologie povrchových úprav po časové a energetické stránce. Nezanedbatelné je i to, že při přípravě retardéru podle vynálezu je výhodou též snížený nárok na tepelnou energii v technologickém proceau výroby a maximální snížení některých, doeud obvykle používaných složek obdobných přípravků.The main advantages of the composition according to the invention appear in its water resistance, which makes it possible to use the composition also in interiors where condensation of vapors sometimes occurs. Another significant advantage of DC is in the controllability of the solidification / cure time of the composition by varying the pH of the composition with the catalyst, as desired by the user. This gives all surface treatment technologies an advantage over time and energy. It is also important that in the preparation of the retarder according to the invention the advantage is also the reduced thermal energy requirement in the technological process of production and the maximum reduction of some components of similar preparations commonly used.
Příklady provedeníExamples
Do roztoku příslušných anorganických solí podle receptury se vmíohá příslušné množství dextrinu do vytvoření homogenní směsi, načež ae katalyzátorem upraví pH směsi tak, aby po smíchání s modifikátorem - pryskyřicí, nabyl modifikát hodnotu 2,5 až 4,1 pH,An appropriate amount of dextrin is added to the solution of the respective inorganic salts according to the recipe until a homogeneous mixture is formed, after which the pH of the mixture is adjusted by the catalyst so that after mixing with the modifier-resin the modification has a pH value of
Hodnoty složek prostředku jeou uvedeny, v hmotnostních dílech, Jak vyplývá z'uvedených příkladů provedení, lze stupeň vodovzdornosti nánosu regulovat modifikátorem.The values of the components of the composition are given in parts by weight. As can be seen from the examples, the degree of water resistance of the coating can be controlled by a modifier.
