Abstract
Description
Foreliggende oppfinnelse vedrører termisk ekspanderbare brannbeskyttelsesmasser henholdsvis brannbeskyttelses-laminater, som inneholder blæregrafitt, en kloroprenlateks inneholdende karboksylgrupper og stoffer som ved brann danner et parakrystallinsk karbongitter, samt en fremgangsmåte for fremstilling derav. The present invention relates to thermally expandable fire protection compounds or fire protection laminates, which contain blister graphite, a chloroprene latex containing carboxyl groups and substances which in case of fire form a paracrystalline carbon lattice, as well as a method for their production.
Termisk ekspanderbare brannbeskyttelsesmasser som består av blæregrafitt, kloroprengummi, en fenolharpiks, et organisk oppløsningsmiddel, samt eventuelt i tillegg av aluminiumhydroksyd og uorganiske fibrer, er eksempelvis beskrevet i AT-PS 360 130. Disse har vist seg spesielt virkningsfulle ved forebyggende brannbeskyttelse, fremfor alt på grunn av deres utmerkede bestandighet mot fuktighet, frost, varme, lys og industriklima, samt på grunn av deres høye esetrykk. Ved innvirkning av varme og ild ekspanderer de i tilfelle brann i åpningen som skal beskyttes ved forholdsvis lav flyteevne. Den ekspanderende massen unnviker derved ikke hindringer, heller ikke i en ikke fullstendig avlukket åpning, og danner på grunn av det høye ese- eller ekspansjonstrykket, som vanligvis ligger over 2 bar, et fast avtetteade sperresjikt, hvorved en videre utbredelse av varme,' riti og røkgasser reduseres eller forsinkes, henholdsvis forhindres helt. Dette tetningsmaterialet har også i ekspandert tilstand en høy mekanisk fasthet. En ulempe ved fremstillingen, bearbeidelsen og anvendelsen av slike masser, er imidlertid sprøheten og den dårlige fleksibiliteten. En ytterligere ulempe består i at det ved fremstillingen anvendes organiske oppløsnings-midler, som krever mer komplisert apparatur og forøket arbeidsinnsats for tilbakevinning av oppløsningsmidler og for å minimalisere en eventuell miljøbelastning forårsaket av oppløsningsmiddel og videre helsefarer. Thermally expandable fire protection compounds consisting of blister graphite, chloroprene rubber, a phenolic resin, an organic solvent, and possibly in addition aluminum hydroxide and inorganic fibres, are for example described in AT-PS 360 130. These have proven to be particularly effective in preventive fire protection, above all on because of their excellent resistance to moisture, frost, heat, light and industrial climate, as well as because of their high pressure. When exposed to heat and fire, they expand in the event of a fire in the opening which must be protected by relatively low buoyancy. The expanding mass thereby does not avoid obstacles, not even in an opening that is not completely sealed off, and due to the high ese or expansion pressure, which is usually above 2 bar, forms a firmly sealed barrier layer, whereby a further spread of heat,' riti and flue gases are reduced or delayed or prevented altogether. This sealing material also has a high mechanical strength in the expanded state. A disadvantage of the production, processing and application of such masses, however, is their brittleness and poor flexibility. A further disadvantage is that organic solvents are used in the production, which require more complicated equipment and increased work effort for the recovery of solvents and to minimize any environmental impact caused by the solvent and further health hazards.
Anvendelsen av oppløsningsmiddelfrie brannbeskyttelsesmasser av blæregrafitt og et polymert bindemiddel, er beskrevet i WO 88/02019. Som polymert bindemiddel er enten et fleksibelt bindemiddel, f.eks. polyvinylacetat, et elastomert bindemiddel, f.eks. en kloroprenpolymer, et duromert bindemiddel, f.eks. en formaldehydharpiks eller et duromert bindemiddel med en tilsats av et fleksibelt bindemiddel mulig. Ulempen ved disse brannbeskyttelsesmassene består imidlertid i at de ved anvendelsen av fleksible eller elastomere bindemidler riktignok har en tilstrekkelig fleksibilitet som er nød-vendig for en enkelt håndtering, men at imidlertid det etter oppesing i branntilfelle dannede sperresjiktet oppviser en for lav stabilitet og hårdhet, som er nødvendig for en optimal avtetting mot en ytterligere brannutbredelse. Brannbeskyttelsesmasser på basis av duromere bindemidler kan bare vanskelig bearbeides grunnet deres høye hårdhet, den i tilfelle brann etter oppesing dannede skorpen er riktignok hard, imidlertid også oppsprukket og sprø og danner ikke noe tilstrekkelig stabilt og tett sperresjikt. The use of solvent-free fire protection compounds of blister graphite and a polymeric binder is described in WO 88/02019. As polymeric binder is either a flexible binder, e.g. polyvinyl acetate, an elastomeric binder, e.g. a chloroprene polymer, a duromeric binder, e.g. a formaldehyde resin or a duromeric binder with an addition of a flexible binder possible. The disadvantage of these fire protection compounds, however, consists in the fact that when flexible or elastomeric binders are used, they do indeed have sufficient flexibility which is necessary for a single handling, but that the barrier layer formed in the event of a fire, however, has too little stability and hardness, which is necessary for optimal sealing against further fire spread. Fire protection compounds based on duromeric binders can only be processed with difficulty due to their high hardness, the crust formed in the event of a fire after burning is indeed hard, but also cracked and brittle and does not form a sufficiently stable and dense barrier layer.
Oppgaven ved foreliggende oppfinnelse består i å overvinne de ved de kjente brannbeskyttelsesmassene opptredende ulemper, og fremfor alt å oppnå mindre sprø masser som i branntilfelle danner et tilstrekkelig stabilt og hardt sperresjikt, og ved hvis fremstilling ingen organiske oppløs*iingsmidler er påkrevd. Denne oppgaven kunne løses med en bfannbeskyttelses-masse som ble oppnådd ved kombinasjon av tre bestemte komponenter. The task of the present invention is to overcome the disadvantages of the known fire protection compounds, and above all to achieve less brittle compounds which in the event of a fire form a sufficiently stable and hard barrier layer, and for the production of which no organic solvents are required. This task could be solved with a waterproofing compound which was achieved by combining three specific components.
Gjenstanden for foreliggende oppfinnelse er følgelig en termisk ekspanderbar brannbeskyttelsesmasse som er kjennetegnet ved at den inneholder 25 til 60 vekt-$ blæregrafitt, 5 til 25 vekt-#, beregnet som faststoff, av en kloroprenlateks med minst 0,3 mol karboksylgrupper pr. 1 kg lateksfaststoff, 3 til 25 vekt-# av stoffer fra gruppen polyakrylnitril, cellulose eller derivater derav, fenolformaldehydharpikser, polyfurfurylalkohol, polyimid, samt eventuelt ytterligere tilsatsstoffer. The object of the present invention is therefore a thermally expandable fire protection compound which is characterized in that it contains 25 to 60 weight-$ of bladder graphite, 5 to 25 weight-#, calculated as solids, of a chloroprene latex with at least 0.3 mol of carboxyl groups per 1 kg latex solid, 3 to 25 weight-# of substances from the group polyacrylonitrile, cellulose or derivatives thereof, phenol formaldehyde resins, polyfurfuryl alcohol, polyimide, as well as any further additives.
Det har derved vist seg spesielt fordelaktig når brannbeskyttelsesmassene ikke inneholder organiske oppløsnings-midler, men at det derimot ved fremstillingen anvendes lateksdispersjoner på utlukkende vandig basis. På grunn av det tilstedeværende restvanninnholdet viser disse brannbeskyttelsesmassene en gunstigere brannoppførsel enn ved anvendelse av organiske oppløsningsmidler. På grunn av fraværet av organiske oppløsningsmidler kan de fremstilles og bearbeides vesentlig enklere og vesentlig mer miljøvennlig. Brannbeskyttelsesmassene ifølge oppfinnelsen viser fremfor alt grunnet innholdet av elastomer kloroprenpolymer, god elastisitet og fleksibilitet, slik at de, henholdsvis derav fremstilte laminater eller plater, er lett anvendbare, bearbeidbare og håndterbare. Avhengig av den aktuelle sammensetningen for brannbeskyttelsesmassen, kan det i branntilfelle oppnås meget høye esetrykk, fortrinnsvis over 5 bar, og dermed en spesielt virkningsfull avtetning. Det etter oppesing dannede sperresjiktet utmerker seg ved sin fasthet, hårdhet og stabilitet, slik at det ikke danner riss og ødelegges ved termiske, mekaniske og aerodynamiske belastninger, samt brannturbulenser i tilfelle brann. It has thereby proven particularly advantageous when the fire protection compounds do not contain organic solvents, but that, on the other hand, latex dispersions on an exclusively aqueous basis are used during production. Due to the residual water content present, these fire protection compounds show a more favorable fire behavior than when organic solvents are used. Due to the absence of organic solvents, they can be manufactured and processed significantly easier and significantly more environmentally friendly. The fire protection compounds according to the invention show, above all due to the content of elastomeric chloroprene polymer, good elasticity and flexibility, so that the laminates or plates produced therefrom are easy to use, process and handle. Depending on the actual composition of the fire protection mass, in the event of a fire very high pressures can be achieved, preferably over 5 bar, and thus a particularly effective seal. The barrier layer formed after raising is distinguished by its firmness, hardness and stability, so that it does not form cracks and is destroyed by thermal, mechanical and aerodynamic loads, as well as fire turbulence in the event of a fire.
Den anvendte blæregrafitten kan eksempelvis -fremstilles ved syrebehandling av en naturgrafitt med rykende salpetersyre, som beskrevet i US-patent nr. 3 574 644 eller av H. Spatzek, Carbon 86 (1986). The bladder graphite used can, for example, be produced by acid treatment of a natural graphite with fuming nitric acid, as described in US patent no. 3 574 644 or by H. Spatzek, Carbon 86 (1986).
Kloroprenlateksen fremstilles vanligvis ved kopolymerisasjon av kloropren med akrylsyre eller metakrylsyre. Slike latekser er eksempelvis i handelen som "Skyprene" (Toyo Soda), "Bayprene" (Bayer), "Butaclor" (Distugil), "Denka Chloro-prene" (Druki Kagaku Kogyo), "Nairit" (UdSSR) eller "Neoprene" (Du Pont). The chloroprene latex is usually produced by copolymerization of chloroprene with acrylic acid or methacrylic acid. Such latexes are for example commercially available as "Skyprene" (Toyo Soda), "Bayprene" (Bayer), "Butaclor" (Distugil), "Denka Chloroprene" (Druki Kagaku Kogyo), "Nairit" (UdSSR) or "Neoprene " (Du Pont).
Polyakrylnitril, cellulose eller derivater derav, fenolformaldehydharpikser, polyfurfurylalkohol eller polyimider danner i tilfelle brann et parakrystallinsk karbongitter. Ved oppvarmingen i tilfelle brann, tverrbindes disse stoffene først, hvorved de sterke intermolekylære bindingene også opprettholdes ved den ytterligere termiske belastningen, som fører til pyrolytisk dekomponering og endelig til dannelse av det parakrystallinske karbongitteret. (Chemie-Ing.-Techn. 42 Nr. 9/10 (1970), s. 659-669.) Tredimensjonale tverrbundne duromerer, som eksempelvis fenolharpikser, viser seg derved som spesielt egnede. Fenolharpikser med tertiære butyl-grupper, som f.eks. p-tert-butylfenolformaldehydharpiks 7520E eller 7522E fra firma Rousselot, viser spesielt gode resultater. Polyacrylonitrile, cellulose or derivatives thereof, phenol formaldehyde resins, polyfurfuryl alcohol or polyimides form a paracrystalline carbon lattice in the event of fire. During the heating in the event of a fire, these substances are first cross-linked, whereby the strong intermolecular bonds are also maintained by the additional thermal load, which leads to pyrolytic decomposition and finally to the formation of the paracrystalline carbon lattice. (Chemie-Ing.-Techn. 42 No. 9/10 (1970), pp. 659-669.) Three-dimensional cross-linked duromers, such as, for example, phenolic resins, thereby prove to be particularly suitable. Phenolic resins with tertiary butyl groups, such as e.g. p-tert-butylphenol formaldehyde resin 7520E or 7522E from the company Rousselot, shows particularly good results.
Tilsatsstoffer som modifiserer brannoppførselen er eksempelvis melamin og dets derivater, forskjellige grafittsalter, cyanursyrederivater, dicyandiamid, halogenhydrokarboner, polyammoniumfosfater og guanidinsalter. Disse stoffene eser ved varmeinnvirkning også under dekomponering. Idet de oppviser en dekomponeringstemperatur som er forskjellig fra blæregrafitt, forhøyes i tilfelle brann også esetrykket med økende temperatur, hvorved en fastere avtetning av åpningen foregår. Additives that modify the fire behavior are, for example, melamine and its derivatives, various graphite salts, cyanuric acid derivatives, dicyandiamide, halogenated hydrocarbons, polyammonium phosphates and guanidine salts. These substances are also exposed to heat during decomposition. As they exhibit a decomposition temperature that is different from blister graphite, in the event of a fire the pore pressure also increases with increasing temperature, whereby a firmer sealing of the opening takes place.
Videre kan det også anvendes ytterligere tilsatsstoffer, som fremfor alt forbedrer fastheten av tetningsmassen i ekspandert tilstand, gjør skorpen fastere og forhøyer vedhenget, som f.eks. uorganiske fibrer, eksempelvis mineral- eller glassfibrer, glasspulver, vermiculitt, bentonitt, kiselsyre, silikater, boraks, stivelse, sukker, klorparafiner, alu-miniumsulfat, aluminiumhydroksyd eller magnesiumhydroksyd. Videre kan det tilsettes flammebeskyttelsesmiddel, eksempelvis halogenerte eller fosforholdige hydrokarboner, som f.eks. tris-klorpropylfosfat, dibromneopentylglykol eller anti-montrioksyd. Videre kommer også slike tilsatsstoffer i betraktning som bevirker økning av skumdannelsen i tilfelle flammedannelse. Slike er eksempelvis salisylsyre, p-hydroksy-benzosyre, PVC, samt nitrogen- eller sulfohydrazider, triazoler, ureadikarboksylsyreanhydrid og ammoniumkarbonat. Gjenstand for oppfinnelsen er videre også et brannbeskyttelseslaminat, kjennetegnet ved at en brannbeskyttelsesmasse som omtalt ovenfor er påført på en bærerbane. Furthermore, further additives can also be used, which above all improve the firmness of the sealing compound in the expanded state, make the crust firmer and increase the attachment, such as e.g. inorganic fibres, for example mineral or glass fibres, glass powder, vermiculite, bentonite, silicic acid, silicates, borax, starch, sugar, chlorinated paraffins, aluminum sulphate, aluminum hydroxide or magnesium hydroxide. Furthermore, flame retardants can be added, for example halogenated or phosphorus-containing hydrocarbons, such as e.g. tris-chloropropyl phosphate, dibromopentyl glycol or antimony trioxide. Furthermore, such additives are also taken into account which cause an increase in foam formation in the event of flame formation. Such are, for example, salicylic acid, p-hydroxy-benzoic acid, PVC, as well as nitrogen or sulphohydrazides, triazoles, ureadicarboxylic anhydride and ammonium carbonate. The object of the invention is also a fire protection laminate, characterized by the fact that a fire protection compound as mentioned above is applied to a carrier web.
Brannbeskyttelsesmassen ifølge oppfinnelsen kan både finne anvendelse som pasta og også i form av plater, lister, bånd eller formgitte gjenstander. Spesielt fordelaktige og enkle ved anvendelse er de ovenfor nevnte brannbeskyttelseslaminatene, hvor brannbeskyttelsesmassen er påkasjert på en bærerbane, eksempelvis en glassfibervlies. Av dekorative grunner og eksempelvis for beskyttelse av brannbeskyttelsesmassen, kan laminatene eller platene være avtettet på en eller begge sider med et dekksjikt, eksempelvis en plast-folie, f.eks. en PVC-folie, papir eller aluminiumblikk. Det er også mulig å utruste brannbeskyttelseslaminatene eller-platene med et klebesjikt, som fordelaktig avdekkes med en slippfolie. The fire protection compound according to the invention can be used both as a paste and also in the form of plates, strips, bands or shaped objects. Particularly advantageous and easy to use are the above-mentioned fire protection laminates, where the fire protection mass is coated on a carrier web, for example a glass fiber fleece. For decorative reasons and for example to protect the fire protection compound, the laminates or plates can be sealed on one or both sides with a covering layer, for example a plastic foil, e.g. a PVC foil, paper or aluminum tin. It is also possible to equip the fire protection laminates or boards with an adhesive layer, which is advantageously uncovered with a release foil.
Ved foreliggende oppfinnelse tilveiebringes videre en fremgangsmåte for fremstilling av en brannbeskyttelsesmasse henholdsvis et brannbeskyttelseslaminat som -omtalt ovenfor, kjennetegnet ved at man blander blæregraf i tir, en karboksylgruppeholdig, fortrinnsvis vandig lateksdispersjon, stoffer fra gruppen polyakrylnitril, cellulose eller derivater derav, fenolformaldehydharpikser, polyfurfurylalkohol, polyimider, samt eventuelt ytterligere tilsatsstoffer under god homogenisering med hverandre, den oppnådde massen påføres eventuelt på en bærerbane og det derved dannede laminatet kasjeres eventuelt med et dekksjikt. The present invention further provides a method for the production of a fire protection compound or a fire protection laminate as - mentioned above, characterized by mixing blister graph in tir, a carboxyl group-containing, preferably aqueous latex dispersion, substances from the group polyacrylonitrile, cellulose or derivatives thereof, phenol formaldehyde resins, polyfurfuryl alcohol, polyimides, as well as possibly further additives under good homogenization with each other, the resulting mass is optionally applied to a carrier web and the resulting laminate is optionally coated with a cover layer.
Brannbeskyttelsesmassen ifølge oppfinnelsen anvendes for brannbeskyttende avtetning henholdsvis fylling av åpninger i bygningsdeler som utgjør et brannavsnitt, som f.eks. fuger mellom murer, hul- henholdsvis mellomrom, murgjennombrudd, kabelgjennomføringer og lignende. Videre kan det fremstilles dørtetninger, vindustetninger eller andre tetninger som i branntilfelle skummer opp og tetter av den på forhånd tilstedeværende spalten eller åpningen. Forbindelsen mellom glass og ramme ved brannbeskyttelsesforglassing ved hjelp av brannbeskyttelsesmassen eller -laminatene ifølge oppfinnelsen, gir også en optimal brannbeskyttelse. Også fremstillingen av hele teglstein er mulig, hvorved gjennombrudd for kabel og rør kles og som ved branninnvirkning danner en sperre. I tilfelle brann skummer denne massen opp ved varmeinnvirkningen og avtetter åpningen slik at en ytterligere gjennomgang av ild og røk, og følgelig en ytterligere utbredelse av brannen, forhindres. The fire protection mass according to the invention is used for fire protective sealing or filling of openings in building parts that constitute a fire section, such as e.g. joints between walls, cavities or spaces, wall penetrations, cable entries and the like. Furthermore, door seals, window seals or other seals can be produced which, in the event of a fire, foam up and seal off the pre-existing gap or opening. The connection between glass and frame during fire protection glazing using the fire protection compound or laminates according to the invention also provides optimal fire protection. The manufacture of whole bricks is also possible, whereby breakthroughs for cables and pipes are covered and which, in the event of a fire, form a barrier. In the event of a fire, this mass foams up due to the heat and seals the opening so that a further passage of fire and smoke, and consequently a further spread of the fire, is prevented.

I en rørerbeholder ble de i tabellene 1 og 2 angitte stoffene (angitt i vektdeler) tilsatt i følgende rekkefølge: tilsatsstoffer, A1(0E)3, fenolharpiks, 50 % vandig kloro-prenlateksdispersjon, blæregrafitt, mineralfibrer ("Inorphil" 061-60, firma G. M. Langer, BRD). Massen ble homogenisert i 1 time ved hjelp av dissolver med tannskive ved 30°C og en pH-verdi på 10 (innstilt ved hjelp av K0H). Viskositeten lå på ca. 4 Pas, målt ved 30°C i Brookfieldviskosimeter (Spindel 7, 20 opm). Den oppnådde brannbeskyttelsesmassen ble deretter sjabret ut på en glassvlies med en flateveKt på 50 g/m<2> og tørket ved 190°C. In a mixing vessel, the substances indicated in Tables 1 and 2 (indicated in parts by weight) were added in the following order: additives, A1(0E)3, phenolic resin, 50% aqueous chloroprene latex dispersion, bladder graphite, mineral fibers ("Inorphil" 061-60, company G. M. Langer, BRD). The mass was homogenized for 1 hour using a dissolver with a toothed disk at 30°C and a pH value of 10 (adjusted using K0H). The viscosity was approx. 4 Pas, measured at 30°C in a Brookfield viscometer (Spindel 7, 20 rpm). The obtained fire protection mass was then drawn onto a glass fleece with a surface weight of 50 g/m<2> and dried at 190°C.
Blæregrafitten ble oppnådd ved syrebehandling av en naturgrafitt med rykende salpetersyre. Som fenolharpiks ble det anvendt en tert-butylfenol-formaldehydharpiks, type 7520E fra firma Rousselot, Frankrike. The blister graphite was obtained by acid treatment of a natural graphite with fuming nitric acid. A tert-butylphenol-formaldehyde resin, type 7520E from the company Rousselot, France, was used as phenolic resin.
Det ble anvendt kommersielt tilgjengelige lateksdispersjoner på basis av et kopolymerisat av kloropren og metakrylsyre. Det i tabell 1 og 2 angitte innhold av karboksylgrupper ble innstilt ved blanding av de følgende lateksene med forskjellig karboksylgruppeinnhold: "Neoprene 115" (Du Pont): 0,33 mol COOH pr. kg. lateksf ast stoff, "Neoprene 750" og "Neoprene 824A": intet COOH-innhold, "Bayprene 4R" (Bayer): 0,23 mol C00H pr. kg. lateksf aststof f. I sammenligningseksempel V 16 ble det ved ellers like betingelser istedenfor den vandige lateksdispersjonen anvendt en 10 % kloropren-oppløsning i toluen. Commercially available latex dispersions based on a copolymer of chloroprene and methacrylic acid were used. The content of carboxyl groups stated in Tables 1 and 2 was set by mixing the following latexes with different carboxyl group content: "Neoprene 115" (Du Pont): 0.33 mol COOH per kg. latex solids, "Neoprene 750" and "Neoprene 824A": no COOH content, "Bayprene 4R" (Bayer): 0.23 mol C00H per kg. latex solid f. In comparative example V 16, under otherwise identical conditions, a 10% chloroprene solution in toluene was used instead of the aqueous latex dispersion.
Egenskapene for brannbeskyttelseslaminatene er også oppført i The properties of the fire protection laminates are also listed in
tabellene 1 og 2. Esetrykket ble målt på prøver med en diameter på 113 mm, som var lagt inn mellom to oppvarmbare metallplater, ved 250°C. Det ved esing dannede trykket ble overført til den nedre platen på en kraftopptaker med trykkanvisning. Det esende materialet var derved ikke avgrenset mot siden og kunne uhindret bre seg ut i planet. Esehøyden ble målt på prøver med en diameter på 50 mm som var lagt inn i en metallsylinder av 100 mm høyde og en inner-diameter på 50 mm. Sylinderen med prøven, som var forbelastet med et stempel på 100 g, ble oppvarmet i 10 minutter i en ovn ved 300°C. tables 1 and 2. The pressure was measured on samples with a diameter of 113 mm, which were inserted between two heatable metal plates, at 250°C. The pressure created by esing was transferred to the lower plate of a force recorder with a pressure indication. The spreading material was thus not bounded to the side and could spread unhindered in the plane. The ass height was measured on samples with a diameter of 50 mm which were placed in a metal cylinder of 100 mm height and an inner diameter of 50 mm. The cylinder with the sample, which was preloaded with a 100 g piston, was heated for 10 minutes in an oven at 300°C.
Eksempel 17: Example 17:
Småbrannforsøk med laminater ifølge eksempel 13 og V 16 Small fire test with laminates according to example 13 and V 16
For å påvise den i tilfelle brann virksomme avtetningen av en åpning med brannbeskyttelsesmassen ifølge oppfinnelsen, ble to 20 cm lange PVC-rør med en ytre diameter på 16 cm og en veggtykkelse på 3,5 mm omviklet med 230 g av et 15 cm bredt brannbeskyttelseslaminat ifølge eksempel 13, som på vlies-siden i tillegg var kasjert med en 0,05 mm tykk aluminium-folie, hvorved blæregrafitten kom til å ligge mot røret. De omviklede rørene ble pakket inn i en mansjett av sinkblikk og skjøvet inn i en boring (22 cm diameter) i en 10 cm tykk lettbetongplate ("Ytong"). Rørene raget på begge sider av platen 5 cm ut av boringen. To demonstrate the effective sealing of an opening in the event of a fire with the fire protection compound according to the invention, two 20 cm long PVC pipes with an outer diameter of 16 cm and a wall thickness of 3.5 mm were wrapped with 230 g of a 15 cm wide fire protection laminate according to example 13, which on the fleece side was additionally lined with a 0.05 mm thick aluminum foil, whereby the blister graphite came to lie against the tube. The coiled pipes were wrapped in a sleeve of zinc tin and pushed into a bore (22 cm diameter) in a 10 cm thick lightweight concrete slab ("Ytong"). The pipes protruded 5 cm from the bore on both sides of the plate.
I to ytterligere, likeartede boringer i lettbetongplaten ble det skjøvet inn to analogt omviklede rør, hvor det imidlertid i stedet for brannbeskyttelseslaminatet ifølge oppfinnelsen, ble anvendt et brannbeskyttelseslaminat ifølge sammenligningseksempel V 16. Det noe mindre fleksible laminatet viste ved vikling småriss og lette bruddstedet-. In two further, similar bores in the lightweight concrete slab, two analogously wrapped pipes were pushed in, where, however, instead of the fire protection laminate according to the invention, a fire protection laminate according to comparative example V 16 was used. The somewhat less flexible laminate showed small cracks when winding and lightened the fracture site.
Deretter ble lettbetongplatene bygd inn i et småbrannkammer ifølge DIN 4102, og etter enhetstemperaturkurven fra den ene siden flammebehandlet til en temperatur på ca. 1 000"C. Brannbeskyttelsesmassene begynte å ese på grunn av varmen etter ca. 4 min, hvorved alle fire PVC-rørene myknet og ble trykket sammen. Tetningene med laminatene ifølge eksempel 13, var fullstendig lukket etter 13 henholdsvis 14 min, de med laminatene ifølge sammenligningseksempel V 16, etter 13 henholdsvis 17 min, slik at ingen røkgasser, brann eller sot lengre trengte ut. Etter 40 min begynte de utoverragende rørstumpene ved tetningene ifølge oppfinnelsen å brytes fra hverandre, mens rørstumpene med avtetningene ifølge sammen-ligningseksemplet begynte å smelte av. Etter 60 min var rørstumpene brukket helt av henholdsvis smeltet, temperaturen for eseskummet ifølge eksempel 13 lå ved 290°C, de for eseskummet ifølge sammenligningseksempel V 16 på 310 henholdsvis 370°C. The lightweight concrete slabs were then built into a small fire chamber according to DIN 4102, and according to the unit temperature curve from one side flame treated to a temperature of approx. 1000"C. The fire protection compounds started to ooze due to the heat after about 4 min, whereby all four PVC pipes softened and were compressed. The seals with the laminates according to example 13 were completely closed after 13 and 14 min respectively, those with the laminates according to comparative example V 16, after 13 and 17 min respectively, so that no smoke gases, fire or soot penetrated anymore. After 40 min, the projecting pipe stubs at the seals according to the invention began to break apart, while the pipe stubs with the seals according to the comparative example began to melt After 60 min, the pipe stumps were completely broken off or melted, the temperature for the foam according to example 13 was 290°C, those for the foam according to comparative example V 16 at 310 and 370°C respectively.
Etter 80 min ble forsøket avbrutt, uten at det kunne fastslås flamme- eller røkgassgjennombrudd. Det viste seg videre at ved anvendelse av brannbeskyttelsesmassene ifølge eksempel 13, hersket det på den siden som vendte fra ilden under forløpet av brannforsøket, en temperatur som var 20-80°C lavere enn ved anvendelse av den vanlige brannbeskyttelsesmassen ifølge sammenligningseksempel V 16. After 80 min, the experiment was interrupted, without any flame or smoke gas breakthrough being determined. It was also found that when using the fire protection compounds according to example 13, a temperature prevailed on the side facing away from the fire during the course of the fire test, which was 20-80°C lower than when using the usual fire protection compound according to comparative example V 16.
Hårdheten av eseskummet ifølge eksempel 13 ble etter av-kjøling målt ved hjelp av en trykkfasthetsprøving på et Zwick-instrument 4045 ifølge DIN 53421, og lå på 0,2 N/mm<2 >(60 1o stuing). The hardness of the foam according to example 13 was measured after cooling by means of a compressive strength test on a Zwick instrument 4045 according to DIN 53421, and was 0.2 N/mm<2> (60 1o stewing).
