Description

Prefabrikert brannhemmende bygningsplate. .Foreliggende oppfinnelse angår en pref abrikeri, brannhemmende bygningsplate , av -den avt som ha-r ett eller flere iiulrom som er fylt .med. et brannhemmende pulverformet material. Prefabricated fire-resistant building board. The present invention relates to a prefabricated, fire-retardant building board, of which one or more hollow spaces are filled with. a fire retardant powdered material.

Prefabrikerte bygningsplater a-v organisk .material som er agglomerert med lim -og bundet "sammen ved hjelp av varme og trykk, f .eks. plater fremstilt av spon av tre eller annet vegetabilsk material, har en begrenset anvendelse i bygningsindustrien på grunn av at -d-e i alminnelighet ikke er tilstrekkelig brannhemmende. Prefabricated building boards a-v organic material which is agglomerated with glue -and bound "together by means of heat and pressure, e.g. boards made from shavings of wood or other vegetable material, have a limited application in the building industry due to the fact that -d-e are generally not sufficiently fire retardant.

Innfdringen i blandingen av spon og lim, av de kjente og i alminnelighet kostbare stoffer som er valgt på grunn av sin egen motstandsdyktighet, mot varme, f.eks. vermikulit, asbest osv., er ikke tilstrekkelige til å gi de nodvendige ildfaste brannhemmende egenskaper. Fra DAS rir. 1.705.698 er det også kjent å sette boraxpulver til blandingen av spon og lim. Ved fremstilling av bygningsplater med hulrom av vesentlig storrelse, de såkalte hulromplater, hvor hulrommene er fylt med pulverformet material, f.eks. sand, har det vist seg at materialet har lett for å renne ut når det oppstår sprekker. The introduction into the mixture of chips and glue, of the known and generally expensive substances which have been chosen because of their own resistance to heat, e.g. vermiculite, asbestos, etc., are not sufficient to provide the necessary refractory fire-retardant properties. From DAS rides. 1,705,698 it is also known to add borax powder to the mixture of shavings and glue. In the production of building panels with cavities of a significant size, the so-called cavity panels, where the cavities are filled with powdered material, e.g. sand, it has been shown that the material easily flows out when cracks occur.

Det har nå vist seg at det kan oppnås en uventet og betydeligIt has now been shown that an unexpected and significant can be achieved

okning i denne ildfasthet ved å bruke- natriumborat for å stabilisere et pulver som inneholdes i et hulrom i platen for derved å hindre at dette pulver renner ut av hulrommet når platen utsettes for en flamme som avdekker hulrommet. Dette er, i henhold til oppfinnelsen- oppnådd ved at pulveret er blandet med en mindre forholdsvis mengde, natriumborat-pulver.. increase in this fire resistance by using sodium borate to stabilize a powder contained in a cavity in the plate to thereby prevent this powder from flowing out of the cavity when the plate is exposed to a flame that exposes the cavity. According to the invention, this is achieved by mixing the powder with a relatively smaller amount of sodium borate powder.

I branntilfelle vil da natriumboratet stabilisere pulveretr ogIn the event of a fire, the sodium borate will stabilize the powder

bringe dette til å stivne slik at det oppnås stive soyler i hulrommene. Herunder utnyttes varmen til å bringe natriumboratet til å stabilisere pulveret. bring this to solidify so that rigid soil is obtained in the cavities. Here, the heat is used to bring the sodium borate to stabilize the powder.

Platen i henhold til oppfinnelsen egner seg spesielt til å utfores som såkalt kanal-bygningsplater som inneholder kanaler som er fylt med et lydisolasjonsmiddel. For å opprettholde lydisolasjonsegenskapene, er det nodvendig at isolasjonsmidlet er i pulverform. The plate according to the invention is particularly suitable for lining as so-called channel building plates containing channels which are filled with a sound insulation agent. In order to maintain the soundproofing properties, it is necessary that the insulating agent is in powder form.

I branntilfelle kan det hende at platen blir angrepet slik at det pulverformete middel vil renne ut av kanalene, somderved ville danne skorstener som danner trekk-kanaler for varmen. In the event of a fire, it may happen that the plate is attacked so that the powdered agent will flow out of the channels, which would thereby form chimneys that form draft channels for the heat.

Det er således oppnådd at isolasjonsmidlet holder seg i pulverform slik at det beholder sine isolasjonsegenskaper, og ikke renner ut i tilfelle av brann. It has thus been achieved that the insulating agent remains in powder form so that it retains its insulating properties, and does not run out in the event of a fire.

Den lpsning oppfinnelsen bringer er meget okonomisk, idet natriumborat er et billig pulver og her benyttes i en meget liten mengde, av størrelsesorden 20-60 gram pr. liter pulver. Den gjor det mulig å oke lydisolasjonsegenskapene for platen, idet det tidligere ikke har vært mulig å bruke store mengder pulverformet isolasjonsmiddel, som jo ville renne ut i tilfelle av brann. The solution the invention brings is very economical, as sodium borate is a cheap powder and is used here in a very small quantity, of the order of 20-60 grams per liter of powder. It makes it possible to increase the sound insulation properties of the board, as it has not previously been possible to use large quantities of powdered insulation, which would run out in the event of a fire.

Det pulver- eller korn- formete middel kan eksempelvis være sand, ildfast lere, sement, kalk, knust porselen, pimpesten, vermikulit, asbest, gips, sagflis osv. og blandinger av disse, idet de beste resultater oppnås med de mest findelte materialer. The powdered or granular agent can be, for example, sand, refractory clay, cement, lime, crushed porcelain, pumice stone, vermiculite, asbestos, gypsum, sawdust, etc. and mixtures of these, as the best results are achieved with the most finely divided materials.

Natriumborat har den egenskap at det binder sammen det pulverformete middel når blandingen av pulver av dette middel og natriumborat blir utsatt for varme. Blandingen vil da danne en blokk som holdes på plass og som er motstandsdyktig mot ilden. Dessuten vil natriumboratet under virkning av varmen, frigjbre Sodium borate has the property of binding together the powdered agent when the mixture of powder of this agent and sodium borate is exposed to heat. The mixture will then form a block which is held in place and which is resistant to the fire. Furthermore, the sodium borate will release under the influence of the heat

gass som bidrar til å hindre fremtrengelsen av flammen i platen. gas which helps to prevent the penetration of the flame into the plate.

Under fremstillingen av platen "kan den underkastes en moderat oppvarming, f.eks. til ca. 60-l80°C, som vil herde minst omkretsen av blandingen og stabilisere denne, slik at blandingen ikke lenger vil kunne renne ut til det ytre av platen når denne gjennomtrenges ved hjelp av en spiss som er trengt inn i platen helt inn til hulrommet. During the production of the plate "it can be subjected to a moderate heating, for example to about 60-180°C, which will harden at least the perimeter of the mixture and stabilize it, so that the mixture will no longer be able to flow to the outside of the plate when this is penetrated by means of a tip that has penetrated the plate all the way to the cavity.

Som eksempel kan det nevnes at en plate av den type som er vistAs an example, it can be mentioned that a plate of the type shown

på tegningen, som i perspektiv viær en parallellepipedisk plate med en kjerne 1 av organisk material som er agglomerert ved liming og pressing, og som har rorformede hulrom 2 som inneholder et lydisolasjonsmiddel 35°g et belegg h limt til platekjernen på den ene store overflate. Sponplaten har en tykkelse på 50 mm og hulrommene inneholder en blanding av bo-rax, som er den vanlige handelsform for natriumborat, og fin torr sand-, i forholdet 3-5 vektprosent borax, har en motstandsdyktighet som er bemerkelsesverdig overfor ild, idet blandingen av silisiumoksyd og natriumborat homogeniseres og herdes under virkningen av varmen, og danner sylinderformete hvite og stive sperringer som lenge motstår ilden. in the drawing, which in perspective shows a parallelepiped plate with a core 1 of organic material which is agglomerated by gluing and pressing, and which has tube-shaped cavities 2 containing a sound insulation agent 35°g a coating h glued to the plate core on one large surface. The chipboard has a thickness of 50 mm and the cavities contain a mixture of borax, which is the usual commercial form of sodium borate, and fine dry sand, in the ratio of 3-5% by weight borax, has a remarkable resistance to fire, as the mixture of silicon oxide and sodium borate are homogenized and hardened under the action of the heat, forming cylindrical white and rigid barriers which resist the fire for a long time.

Natriumboratet kan tilsettes andre fyllstoffer. Spesielt egnet er det å sette natriumboratet til asbest som er i form av et så fint pulver som mulig, idet finheten av asbestpulveret fortrinnsvis er av samme størrelsesorden som finheten av mel eller talkum. The sodium borate can be added to other fillers. It is particularly suitable to add the sodium borate to asbestos which is in the form of as fine a powder as possible, the fineness of the asbestos powder being preferably of the same order of magnitude as the fineness of flour or talc.

En mengde av 1 til 10 vektprosent, fortrinnsvis 5 til 10 vektprosent, av asbestpulver i forhold til limet kan med fordel settes til limet når denne tilsetning ledsages av en tilsetning, av natriumborat, mens asbestpulveret, hvis det ble brukt sammen med bare lim, måtte bli fort inn i meget storre mengde, opptil 50 vektprosent av limet, noe som forovrig i praksis ville gjore det nodvendig å oke mengden av lim for å oppnå en tilstrekkelig klebeevne. An amount of 1 to 10 percent by weight, preferably 5 to 10 percent by weight, of asbestos powder relative to the adhesive may advantageously be added to the adhesive when this addition is accompanied by an addition, of sodium borate, whereas the asbestos powder, if used with only adhesive, would have to quickly into a very large quantity, up to 50 percent by weight of the glue, which would otherwise in practice make it necessary to increase the amount of glue to achieve sufficient adhesiveness.

Det har dessuten vist seg at tilstedeværelsen av dette asbestpulver på en overraskende, måte hindrer at platen sveller hvis den utsettes for vann. It has also been shown that the presence of this asbestos powder surprisingly prevents the sheet from swelling if exposed to water.

Det kan forekomme at. asbestpulveret danner en slags kappe rundt hvert spon, bestående av en sky av partikler som ligger meget tett og holdes sammen ved hjelp av limet og som isolerer sponet og ligger i nær berbring med dette og derved både forhindrer at sponet kan svelle ved opptagelse av vann og å destilleres ved berbring med en flamme. It may happen that. the asbestos powder forms a kind of mantle around each chip, consisting of a cloud of particles that lie very close and are held together by means of the glue and which insulates the chip and is in close contact with it and thereby both prevents the chip from swelling when absorbing water and to be distilled by berbering with a flame.

Disse egenskaper kan også skyldes samvirke mellom limet og det middel som er innfort. These properties can also be due to interaction between the adhesive and the agent that has been incorporated.

Som eksempel kan det nevnes at en plate med en tykkelse på 60 mm av treflis som er agglomerert, og som inneholder borax blandet med limet for agglomerering av sponene og. utsatt for virkningen av en bensindrevet meget stor sveiselampe ikke ble gjennomtrengt av flammen etter å ha vært utsatt for den i 7 timer. As an example, it can be mentioned that a plate with a thickness of 60 mm of wood chips which is agglomerated, and which contains borax mixed with the glue for agglomeration of the chips and. exposed to the action of a gasoline-powered very large welding torch was not penetrated by the flame after being exposed to it for 7 hours.

I en blanding som er særlig egnet for bruk i en plate i henhold til oppfinnelsen, med 100 kg trespon og ca.30 kg bruksferdig plastlim, var den forholdsvise mengde av boraxpulve-r 0,3 til 3 kg, fortrinnsvis 0,6 til 1,5 kg, og den forholdsvise mengde av asbestpulver var 0,3 til 3 kg, fortrinnsvis 1,5 til 3 kg. In a mixture which is particularly suitable for use in a plate according to the invention, with 100 kg of wood shavings and approx. 30 kg of ready-to-use plastic glue, the relative amount of borax powder was 0.3 to 3 kg, preferably 0.6 to 1 .5 kg, and the relative amount of asbestos powder was 0.3 to 3 kg, preferably 1.5 to 3 kg.

Grunntanken i oppfinnelsen, nemlig at det i plater med rbrformete hulrom som er fylt med pulver fores inn natriumborat sammen med meget fint asbestpulver, kan tilpasses forskjellige materialer-som brukes for fremstilling av plater og spesielt til agglomerater åv vegetabilske stoffer, trespon eller flis, lin, halm-osv. og den kan også tilpasses forskjellige limarter som brukes 1 disse plater, fortrinnsvis lim av urinstoff-formol-typen og melamin-lim, og f.eks. det lim som er kjent under varemerket Kaurit. Men oppfinnelsen er selvsagt ikke begrenset til noen spesiell type agglomerat eller lim. The basic idea of the invention, namely that sodium borate together with very fine asbestos powder is introduced into plates with tube-shaped cavities filled with powder, can be adapted to different materials - which are used for the production of plates and especially to agglomerates of vegetable substances, wood shavings or chips, linen , straw etc. and it can also be adapted to different types of glue used in these boards, preferably glue of the urea-formol type and melamine glue, and e.g. the glue known under the trademark Kaurit. But the invention is of course not limited to any particular type of agglomerate or glue.

Oppfinnelsen kan tilpasses ethvert bygningselement som inneholder The invention can be adapted to any building element that contains

hulrom som er fylt med en pulverformet blanding, idet innholdet av natriumborat forbedrer den brannhemmende egenskap for elementet. Natriumboratet kan herunder eksempelvis være blandet med sand, og/eller- malt pimpesten og/eller et annet kjent isolasjonsmiddel. Disse blandinger kan spesielt være inneholdt mellom to metallvegger, for eksempel for brannsperring, eller i en kanal for å beskytte en del som er omgitt av kanalen, f.eks. en soyle eller et ror. Den dobbelte vegg som inneholder blandingen kan utfores i organiske cavities that are filled with a powdery mixture, the sodium borate content improving the fire-retardant properties of the element. The sodium borate may, for example, be mixed with sand, and/or ground pumice stone and/or another known insulating agent. These mixtures may in particular be contained between two metal walls, for example for fire protection, or in a channel to protect a part surrounded by the channel, e.g. a soyle or a rudder. The double wall containing the mixture can be lined in organic

materialer, f.eks. tre, plast osv. materials, e.g. wood, plastic, etc.
