Brannbeskyttende belegningssystem og anvendelseFire protective coating system and application
derav.hence.
Foreliggende oppfinnelse angår et nytt forbedret brannbeskyttende belegningssystem ved hjelp av hvilket man kan oppnå en beskyttelse av bærende bygningselementer, i første rekke av metall, i tilfelle brann, på mer enn 60 min. The present invention relates to a new improved fire-protective coating system by means of which it is possible to achieve a protection of load-bearing building elements, primarily of metal, in the event of a fire, of more than 60 minutes.
Det er kjent at bygningsdeler av metall, betong eller lignende kan beskyttes i branntilfelle ved hjelp av beskyttelses-belegg eller varmeisolerende belegg mot flamme- eller varmepåvirkning i en viss tid. Derved anvender man blant annet slike som i branntilfelle på grunn av varmepåvirkningen skummer opp, og således danner et relativt tykt, dårlig varmeledende dog til metallsubstratet godt vedheftende skumsjikt som gir en god beskyttelse. It is known that building parts made of metal, concrete or the like can be protected in the event of fire by means of protective coatings or heat-insulating coatings against flame or heat effects for a certain period of time. Thereby, one uses, among other things, those that foam up in the event of a fire due to the influence of heat, thus forming a relatively thick, poorly heat-conducting, but well-adherent foam layer to the metal substrate, which provides good protection.
Fra østerrisk patent nr. 330.320 er det kjent at brannbeskyttende malings- hhv. belegningssysterner som på grunn av varmeutviklingen skummer opp i branntilfelle, fortrinnsvis kan fremstilles på basis av oppblæringsdyktig grafitt, hvorved denne grafitt som kan blæres opp til 10-40 ganger det.opprinnelige volum, er bundet ved tilsetning av en halogenholdig elastomer og en fenolaldehydharpiks som ved varmepåvirkning danner et porøst, men fast kokssjelett. From Austrian patent no. 330,320 it is known that fire protective paint or coating cisterns which, due to the generation of heat, foam up in the event of a fire, can preferably be produced on the basis of expandable graphite, whereby this graphite, which can be inflated to 10-40 times its original volume, is bound by the addition of a halogen-containing elastomer and a phenolaldehyde resin which heat action forms a porous but solid coke shell.
Det kjente brannbeskyttelsesbelegningssystem bygges opp av tre sjikt, hvorved den oppblæringsgrafittholdige komponent utgjør mellomsjiktet som påføres på et i og for seg kjent korro-sjonsbeskyttelsessjikt (grunnmaling) og- som avdekkes med et selvherdende silikatsjikt. The known fire protection coating system is made up of three layers, whereby the expanding graphite-containing component forms the middle layer which is applied to a known per se corrosion protection layer (primer paint) and which is covered with a self-hardening silicate layer.
Dette selvherdende silikatdekksjikt oppnås fra en blanding av silisiumsyreforbindelser slik som vannglass, reaktive metallpulvere, metalloksyder eller metallhydiroksyder som danner et med vannglass vannuømfintlig sjikt'. For å sikre en mest mulig This self-hardening silicate cover layer is obtained from a mixture of silicic acid compounds such as water glass, reactive metal powders, metal oxides or metal hydroxides which form a layer impermeable to water glass. To ensure as much as possible
høy vannresistens for silikatsjiktet, anbefales det i til-high water resistance for the silicate layer, it is recommended in
legg å benytte mest mulig alkalifattige alkalisilikater.try to use alkali-poor alkali silicates as much as possible.
Dette dekksjikt har til oppgave å forhindre en avskalling av det oppblærede dekksjikt også etter oppblæring i branntilfelle. Med dette belegningssystem kan ved en utprøvning i henhold til DIN 4102 i praksis i brannforsøk i liten målestokk (i henhold til DIN 18082)., oppnås en brannmotstandsklasse F 30 med stor sikkerhet. I virkeligheten utgjorde ved disse prøver brannmotstandstiden ca. 40-45 min. En beskyttelse over 60 min, noe som tilsvarer brannmotstandsklasse F 60, kunne imidlertid ikke oppnås da beskyttelsesvirkningen for det virksomme sjikt ikke helt ut var tilstrekkelig og da det i tillegg i dekksjiktet, spesielt ved belegning av profiler, oppsto sprekker på hjørner og kanter, noe som mulig-gjorde varmeangrep under lufttilgang på de godt isolerende, men dog ved høyere temperatur oksydasjonsømfintlige mellomsjikt, noe som raskt forringet beskyttelsesvirkningen. This cover layer has the task of preventing peeling of the blistered cover layer also after blistering in the event of a fire. With this coating system, a test in accordance with DIN 4102 in practice in small-scale fire tests (according to DIN 18082)., a fire resistance class F 30 can be achieved with great certainty. In reality, in these tests the fire resistance time was approx. 40-45 min. A protection of more than 60 minutes, which corresponds to fire resistance class F 60, could not be achieved, however, as the protective effect for the active layer was not entirely sufficient and as, in addition, in the cover layer, especially when covering profiles, cracks appeared on corners and edges, which which enabled heat attack during air access on the well-insulating, but at higher temperature oxidation-sensitive interlayers, which quickly deteriorated the protective effect.
Det er nå funnet at disse mangler kan oppheves og at det på basis av oppblæringsdyktig grafitt kan oppnås et beskyttelses-belegg som sikrer oppnåelse av en flammemotstandsklasse F 60, også ved belegning over kanter og hjørner, når man for binding av den oppblæringsdyktige grafitt, anvender en spesiell fenolharpiks i det virksomme sjikt og i tillegg tilsetter som ytterligere komponent, aluminiumhydroksyd i virkesjiktblandingen, noe som på grunn av den ved varmepåvirkning opptredende endoterme av-vanningsprosess, utøver en ytterligere beskyttelsesvirkning på grunn av den oppstående vanndamp og når dekksjiktet ikke er bygget opp av metallsilikater som er gjort vannuømfintlige ved reaksjon med metaller eller metalloksyder, men.anvender et dekksjikt av i det minste delvis fast alkalisilikat. It has now been found that these defects can be eliminated and that a protective coating can be obtained on the basis of intumescent graphite which ensures the achievement of a flame resistance class F 60, also when coating over edges and corners, when for bonding the intumescent graphite, use a special phenolic resin in the active layer and in addition adds, as a further component, aluminum hydroxide in the active layer mixture, which, due to the endothermic dewatering process occurring under the influence of heat, exerts an additional protective effect due to the arising water vapor and when the cover layer is not built up of metal silicates which have been rendered insensitive to water by reaction with metals or metal oxides, but using a covering layer of at least partially solid alkali silicate.
Gjenstand for foreliggende oppfinnelse er i henhold til dette et brannbeskyttende belegningssystem for bygningsdeler av metall, betong eller ligendene, bestående av et i og for seg kjent korrosjonshemmende grunnsjikt, ét oppskummende og brannbeskyttende virkesjikt på basis av blæregrafitt og en blanding av en halogenholdig elastomer og en fenolharpiks som bindemiddel, og et selvherdende silikatisk dekksjikt, og oppfinnelses-gjenstanden karakteriseres ved at det i virkesjiktet på basis av blæregrafitt som fenolharpiks, anvendes en alkylfenolformaldehydharpiks og at virkesjiktet som er tilstede i en mengde av minst 4 kg/m 2, i tillegg inneholder 30-80 deler aluminiumhydroksyd pr. 100 deler blæregrafitt og at det silikåtiske dekksjikt er oppstått ved blanding og utherdihg av 100 deler K-vannglass med 30-130 deler fast Na-vannglass, 0,5-7 deler PB^O^, i nærvær av vann som. fortynningsmiddel, hvorved dette dekksjikt eventuelt kan være iblandet mineralsk fibermateriale og/eller alkalihydroksyd. Ved halogenholdig elastomer dreier det seg fortrinnsvis The object of the present invention is, according to this, a fire-protective coating system for building parts made of metal, concrete or the alloys, consisting of a known per se corrosion-inhibiting base layer, a foaming and fire-protective active layer based on blister graphite and a mixture of a halogen-containing elastomer and a phenolic resin as binder, and a self-hardening silicate cover layer, and the object of the invention is characterized by the fact that in the active layer based on blister graphite as phenolic resin, an alkylphenol formaldehyde resin is used and that the active layer, which is present in an amount of at least 4 kg/m 2 , additionally contains 30-80 parts aluminum hydroxide per 100 parts bladder graphite and that the silicate cover layer has been created by mixing and curing 100 parts K-water glass with 30-130 parts solid Na-water glass, 0.5-7 parts PB^O^, in the presence of water which. diluent, whereby this cover layer can optionally be mixed with mineral fiber material and/or alkali hydroxide. In the case of halogen-containing elastomer, it preferably turns
om polyklorbutadien som eventuelt kan være nedbygget ved mastisering. For å- oppnå en god binding av blæregrafitten, anvendes det hensiktsmessig 15-30 og fortrinnsvis 20-28 deler polyklorbutadien pr. 100 deler blæregrafitt, uansett mastisering eller ikke.0about polychlorobutadiene which may possibly be reduced by mastication. In order to achieve a good bond of the blister graphite, 15-30 and preferably 20-28 parts of polychlorobutadiene per 100 parts bladder graphite, whether masticated or not.0
Alkylfenolformaldehydharpiksen anvendes hensiktsmessigThe alkylphenol formaldehyde resin is suitably used
i slike mengder at det pr. 100 deler blæregrafitt kommer 5-25 deler alkylfenolformaldehydharpiks.'Spesielt gunstig har t-butylfenolformaldehydharpiks vist seg, imidlertid er også andre alkylf enolf ormaldehydharpikser slik som f,, eks. oktylfenylf ormal-dehydharpiks , godt brukbar. in such quantities that per 100 parts of bladder graphite contain 5-25 parts of alkylphenol formaldehyde resin. t-Butylphenol formaldehyde resin has proved particularly advantageous, however, other alkylphenol formaldehyde resins such as f,, e.g. octylphenylformaldehyde resin, very usable.
Anvendelse av denne oppfinnelsesmessige bindemiddelkom-binasjon er vesentlig da kun i dette tilfelle blæregrafitten som jo blæres opp kraftig i branntilfelle, i tilstrekkelig grad holdes sammen slik at den ikke smuldrer av eller slik at det ikke oppstår sprekker på hjørner og kanter, noe som tillater fri tilgang av flammen til bygningsdelen. Herved virker polyklorbutadien som et i varmen termoplastisk bindemiddel, fenolhar-piksen imidlertid som koksdanner som fester sjiktet. En ytterligere festing i oppblæret tilstand kan i tillegg oppnås når virkesjiktet inneholder mineralske fiberstoffer slik som asbest eller steinull, f.eks. med en fiberlengde på 0,5-10 mm. Andelen av disse fibere pr. 100 deler blæregrafitt kan hensiktsmessig utgjøre 5-20 deler. Naturligvis kan bindemiddelblandingen i-blandes de vanlige stabiliserende tilslag mot aldring. Slike er f.eks. sterisk behindrede fenoler eller oksyder av magnesium eller sink (syreakseptorer). The use of this inventive binder combination is essential as only in this case the blister graphite, which in fact inflates strongly in the event of a fire, is sufficiently held together so that it does not crumble off or so that cracks do not occur on corners and edges, which allows free access of the flame to the building part. In this way, polychlorobutadiene acts as a thermoplastic binder in the heat, while the phenolic resin acts as a coke former that fixes the layer. A further fixing in the inflated state can also be achieved when the working layer contains mineral fiber substances such as asbestos or stone wool, e.g. with a fiber length of 0.5-10 mm. The proportion of these fibers per 100 parts of bladder graphite can suitably amount to 5-20 parts. Naturally, the binder mixture can be mixed with the usual anti-ageing stabilizing aggregates. These are e.g. sterically hindered phenols or oxides of magnesium or zinc (acid acceptors).
Vesentlig for forstyrrelsesfri virkning av virkesjiktet er også dekksjiktet som på den ene side beskytter virkesjiktet og skal holde dette sammen i tilfelle oppblæring, som imidlertid ikke skal hindre virkesjiktet ved oppblæring, og også må være tilstrekkelig gassgjennomtrengelig slik at oppstående gasser ubehindret kan gå gjennom. Alt dette oppnås når man i motsetning til den kjente teknikk anvender et dekksjikt som ikke danner noe glatt fast porefritt overtrekk, men tvert imot danner et sjikt som ved tørking danner porer slik at man sikrer ubehindret gass-gjennomgang. Dette oppnås med dekksjiktet ifølge oppfinnelsen på basis av kali- og natronvannglass, fortrinnsvis slike med en modul på mindre enn 3,5, og som videre inneholder Pb^O^som fluss-middel. Mengden Pb^04 kan holdes relativt lav, den utgjør fortrinnsvis 0,5-7 deler/100 deler kalivannglass. Essential for the disturbance-free effect of the working layer is also the cover layer which, on the one hand, protects the working layer and must hold it together in the event of swelling, which, however, must not obstruct the working layer in the event of swelling, and must also be sufficiently gas permeable so that rising gases can pass through unimpeded. All this is achieved when, in contrast to the known technique, a cover layer is used which does not form a smooth firm pore-free covering, but on the contrary forms a layer which, when dried, forms pores so that unobstructed gas passage is ensured. This is achieved with the cover layer according to the invention on the basis of potash and sodium hydroxide glass, preferably those with a modulus of less than 3.5, and which also contain Pb^O^ as a flux. The quantity of Pb^O4 can be kept relatively low, it preferably amounts to 0.5-7 parts/100 parts potash water glass.
Som nevnt ovenfor, innføres det i dekklakken en viss mengde fast natronvannglass, noe som gir en fordelaktig virkning på utvidelsesevnen for dekksjiktet. Det er også mulig å forhøye-alkaliinnholdet i dekkpåføringsmassen før påføring ved tilsetning av alkalilut, fortrinnsvis natronlut, da man derved oppnår en god holdbarhet for massen før påføring.- Generelt bør vektforholdet mellom 1^0 og Na20 i dekksjiktet i forhold til SiG^i dette omtrent ligge på 25-35:70, hvorved vektforholdet mellom K20 og Na20 omtrent utgjør 2:1. As mentioned above, a certain amount of solid soda ash is introduced into the top coat, which has a beneficial effect on the expansion capability of the top layer. It is also possible to increase the alkali content in the cover application mass before application by adding alkaline lye, preferably caustic soda, as this achieves a good durability for the mass before application.- In general, the weight ratio between 1^0 and Na20 in the cover layer should be this should be approximately 25-35:70, whereby the weight ratio between K20 and Na20 is approximately 2:1.
Påføringen av det brannbeskyttende belegningssystem ifølge oppfinnelsen, noe som også utgjør en gjenstand for fore-' liggende oppfinnelse, baseres på en påhverandre følgende på-føring av alle tre sjikt. Det i og for seg kjente korrosjonshemmende grunnsjikt påføres på vanlig måte som underste sjikt. Som korrosjonsbesj iktende grunnmaling, har spesielt vist seg gunstig en maling på basis av alkydharniks.. Andre systemer slik som f.eks. epoksyharpikslakk, er eventuelt også brukbar. Deretter følger etter tørking, påføring av virkesjiktet. Best-andelene av virkesjiktet kan herved være så godt fortynnet med organiske oppløsningsmidler slik som aromatiske hydrokarboner (benzen, toluen, xylenl eller ved blanding av disse med ketoner, fortrinnsvis aceton eller metyletylketon og benzinhydrokarboner, at det oppstår en sprøytedyktig hhv. påstrykningsdyktig-masse. Mengden av oppløsningsmiddel utgjør herved vanligvis 100-200 deler/100 deler blæregrafitt. Denne masse kan enten påføres med sprøytepistol eller ved sparkling, noe som man må ta hensyn til i forbindelse med mengden av oppløsningsmiddel. En tilstrekkelig beskyttelsesvirkning, dvs. sikker oppnåelse av flammemotstandsklasse F 60, oppnås kun i det tilfelle når virkesjiktpåføringen, beregnet på tørt belegg, utgjør minst 4 kg/m 2 . Fortrinnsvis påføres mellom 4 og 5 kg/m 2, noe som er mulig både ved en enkelt påføring og ved flere påhverandre påføringer. The application of the fire-protective coating system according to the invention, which also constitutes an object of the present invention, is based on a successive application of all three layers. The corrosion-inhibiting base layer known in and of itself is applied in the usual way as the bottom layer. As a corrosion-resistant primer, a paint based on alkyd resins has proven particularly beneficial. Other systems such as e.g. epoxy resin varnish, is possibly also usable. Then, after drying, the application of the active layer follows. The best parts of the active layer can thereby be so well diluted with organic solvents such as aromatic hydrocarbons (benzene, toluene, xylene or by mixing these with ketones, preferably acetone or methyl ethyl ketone and petrol hydrocarbons, that a sprayable or paintable mass is produced. The amount of solvent is usually 100-200 parts/100 parts of blister graphite. This mass can either be applied with a spray gun or by sandblasting, which must be taken into account in connection with the amount of solvent. A sufficient protective effect, i.e. secure attainment of the flame resistance class F 60, is only achieved in the case when the working layer application, calculated on a dry coating, amounts to at least 4 kg/m 2. Preferably between 4 and 5 kg/m 2 are applied, which is possible both with a single application and with several successive applications.
Selvfølgelig kan man også velge en høyere påføringsmengde, dog spiller ved påføringsmengder på over 5 kg/m 2 også økonomiske betraktninger en viss rolle i tillegg til den sjikttykkelse Of course, you can also choose a higher application amount, however, with application amounts of more than 5 kg/m 2 , economic considerations also play a certain role in addition to the layer thickness
som kan tolereres for angjeldende bygningsdel.which can be tolerated for the building in question.

The proportion of asbestos fibers can be up to 30 parts, the proportion of solid alkali hydroxide e.g. about. 10 parts.
