Description
Foreliggende oppfinnelse angår anvendelse av et adhesiv bestående av vannglass med en tilsetning i mest mulig fin- The present invention relates to the use of an adhesive consisting of water glass with an additive as fine as possible
fordelt form av leiremineralske stoffer for festing av en metallfolie til en mineralfiberplate. distributed form of clay mineral substances for attaching a metal foil to a mineral fiber board.
Det er kjent å anvende et organisk klebestoff som bindemiddel eller klebemiddel for å feste en metallfolie på en mineralfiberplate (US-Patent 2.890.147 og US Patent 3.276.928). It is known to use an organic adhesive as a binder or adhesive to attach a metal foil to a mineral fiber board (US Patent 2,890,147 and US Patent 3,276,928).
Anvendelsen av slike organiske klebestoffer har dog den mangel at de ved hjelp av disse stoffer kasjerte mineralfiberplater ikke mer oppfyller de forskrifter som må oppfylles med henblikk på ikke-brennbarhet av varme- og lyddempende materialer. The use of such organic adhesives, however, has the disadvantage that the mineral fiber boards coated with these substances no longer meet the regulations that must be met with regard to the non-combustibility of heat- and sound-absorbing materials.
For å brannsikre isoleringer av glass- eller mineralfibre er det i og for seg allerede fra DE-Patent 957.465 kjent en fremgangsmåte der oppløselige silikater, d.v.s. uorganiske stoffer, i form av et silikat med lav alkalitet finner anvendelse, In order to fireproof insulation of glass or mineral fibres, a method is already known from DE-Patent 957,465 in which soluble silicates, i.e. inorganic substances, in the form of a silicate with low alkalinity find application,
og der silikatet påføres på ytterflaten av isoleringen. Derved oppnås imidlertid kun en belegning av en slik dempende plate. and where the silicate is applied to the outer surface of the insulation. Thereby, however, only a coating of such a damping plate is achieved.
Som foretrukket sammensetning av et slikt silikat nevnes en A preferred composition of such a silicate is mentioned
som består av 1 vektdel Na^O på 3,2-3,65 (fortrinnsvis 3,4) vektdeler Si02. which consists of 1 part by weight Na^O of 3.2-3.65 (preferably 3.4) parts by weight SiO 2 .
Hovedmålet for denne forholdsregel er å gi isoleringen den ønskede flammesikring, men samtidig å unngå at silikatet på grunn av høy alkalitet angriper glass- eller mineralfibrene. Dessuten var det tilstrebet å gjennomføre behandlingen av isolerplaten slik at det ikke lenger kunne forekomme skadelig irritasjon av huden ved behandling av isoleringen. The main aim of this precaution is to give the insulation the desired flame protection, but at the same time to avoid the silicate attacking the glass or mineral fibers due to high alkalinity. In addition, the aim was to carry out the treatment of the insulation board so that harmful irritation of the skin could no longer occur when treating the insulation.
Problemet i forbindelse med å impregnere mineralfiberlegemer med anorganiske stoffer for i størst mulig grad å nedsette brennbarheten har i lang tid beskjeftiget fagfolk på dette området. The problem in connection with impregnating mineral fiber bodies with inorganic substances in order to reduce their flammability to the greatest possible extent has occupied professionals in this area for a long time.
I US-Patent 3.002.857 er det nevnt at anvendelsen av vannglass eller natriumsilikat som bindemiddelbestanddelder ved fremstilling av overtrukkede eller bundede glassfiberlegemer på grunn av den høye natriumionekonsentrasjonen i kommersielt til-gjengelig natriumsilikater kan ha tilfølge en ødeleggelse og et angrep på glassfibrene, slik at det oppstår produkter som er svake og sprø. Dette patent nevner betingelser som må still-es til en overtrekks- eller bindemiddelsammensetning for glassfibre og/eller -filmer: (1) Bestanddelene i sammensetningen som utgjør bindemidlet må oppvise en god binding med overflaten av glassfibrene eller glassfilmen ved en tempereatur under smeltetempera-turen for glasset som utgjør fibrene. Denne bindingen må være fullstendig i løpet av et forholdsmessig kort tidsrom på ca. 0,25-60 minutter og ved' en temperatur under 650°C og fortrinnsvis innen området 315°C til 650°C. (2) Bindemidlet eller overtrekket må ikke påvirkes av fuktighet og må ikke svelle under fuktige betingelser etter av-setning på overflaten av mineralfiberplaten. (3) Bestanddelene i binde- eller overtrekksmidlet må ikke angripe glassfibrene slik tilfellet er med natriumsilikat, når de foreligger i form av en sammensetning som påføres på overflaten av glassfibre eller glassfilmer. Dessuten må de ikke ugunstig påvirke fastheten, bøyeligheten og andre ønskelige egenskaper for glassfibrene eller -film-ene. (4) Et slikt uorganisk bindemiddel eller overtrekksmiddel må ikke virke korroderende på metall. (5) Sammensetningen må kunne fremstilles med små omkost-ninger og av forholdsvis lett tilgjengelige materialer og ved hjelp av vanlige innretninger for å oppnå et forbedret produkt uten vesentlige omkostningsforhøyelser. In US-Patent 3,002,857 it is mentioned that the use of water glass or sodium silicate as binder components in the production of coated or bonded glass fiber bodies, due to the high sodium ion concentration in commercially available sodium silicates, may result in destruction and an attack on the glass fibers, so that this results in products that are weak and brittle. This patent mentions conditions that must be met for a coating or binder composition for glass fibers and/or films: (1) The components of the composition that make up the binder must exhibit a good bond with the surface of the glass fibers or glass film at a temperature below the melting temperature for the glass that makes up the fibers. This bonding must be complete within a relatively short period of approx. 0.25-60 minutes and at a temperature below 650°C and preferably within the range 315°C to 650°C. (2) The binder or coating must not be affected by moisture and must not swell under moist conditions after deposition on the surface of the mineral fiber board. (3) The components of the binding or coating agent must not attack the glass fibers as is the case with sodium silicate, when they are in the form of a composition that is applied to the surface of glass fibers or glass films. Moreover, they must not adversely affect the strength, flexibility and other desirable properties of the glass fibers or films. (4) Such an inorganic binder or coating agent must not have a corrosive effect on metal. (5) The composition must be able to be produced at low cost and from relatively easily available materials and with the help of common devices in order to obtain an improved product without significant increases in costs.
For å nå dette mål, foreslår US-Patent 3.002.857 en sammensetning i form av et vandig system der de i sammensetningen foreliggende stoffer reagerer med glassoverflåtene med de ovenfor angitte forholdsvis høye temperaturer slik at det oppstår et glasslignende materiale som forbinder seg fast med glass-fiberoverflåtene. In order to achieve this goal, US-Patent 3,002,857 proposes a composition in the form of an aqueous system in which the substances present in the composition react with the glass surfaces at the above-mentioned relatively high temperatures so that a glass-like material is formed which firmly connects with glass - the fiber surfaces.
Bortsett fra at fremstillingen av et slikt belegg krever anvendelse av de angitte uøkonomiske høye temperaturer, oppnås det med et slikt bindemiddel eller overtrekksmiddel kun et overtrekksstoff for de enkelte fibre henholdsvis for de på overflaten liggende fibre, hvilket reagerer med glass- og andre mineralfibre. Det oppstår åpenbart ikke noe sammenhengende sjikt på det fra slike behandlede fibre fremstilte produkt, men kun et på hver enkel fiber fast bundet sjikt for å modifisere fibrene slik at de oppstilte krav kan oppfylles. Apart from the fact that the production of such a coating requires the use of the specified uneconomical high temperatures, with such a binder or coating agent only a coating material is obtained for the individual fibers or for the fibers lying on the surface, which reacts with glass and other mineral fibers. There is obviously no continuous layer on the product made from such treated fibres, but only a firmly bonded layer on each individual fiber to modify the fibers so that the stated requirements can be met.
I US-Patent 3.002.857 er det også allerede nevnt anvendelse av fyllstoffer i form av leire eller andre vannoppløselige eller vanndispergerende silikater, karbonater, hydroksyder eller oksyder av metaller som vanligvis foreligger i glass. In US-Patent 3,002,857 it has also already been mentioned the use of fillers in the form of clay or other water-soluble or water-dispersing silicates, carbonates, hydroxides or oxides of metals which are usually present in glass.
I US-Patent 3.286.785 og i US-Patent 3.490.065 nevnes en lyd-og varmedempende plate av mineralfibre som i det minste på en side oppviser et tykt sjikt hvis funksjon i første linje skal bestå i at sjiktet blir det hovedsakelige eller eneste bærende element og således den eneste kilde for strukturell stabilitet i platen ved svekning, mykning eller smelting av fibrene i platen og ved forbrenning av harpiksbindemidlet for mineralfibrene. In US-Patent 3,286,785 and in US-Patent 3,490,065, a sound- and heat-absorbing plate made of mineral fibers is mentioned which, at least on one side, has a thick layer whose function in the first line is to consist in the layer becoming the main or only load-bearing element and thus the only source of structural stability in the plate when weakening, softening or melting the fibers in the plate and when burning the resin binder for the mineral fibers.
Det for fremstilling av dette sjikt tjenende impregnerings-middel inneholder knust uorganisk gods og en bindemiddelfase som igjen består av 5-95 vekt-% kiselsyresol og 95-5 vekt-% bentonitt, hvorved total-faststoffandelen i impregneringsmidlet ligger ved 2-25 vekt-%. Det fremstilte materiale oppviser altså 1-20 vekt-% silisiumsyresol og 1-15 vekt-% bentonitt, hvorved det i tillegg kan være tilsatt bindeleire og feltspat. Videre kan det tilsettes fyllstoffer. Slike impregnerings-midler er dog meget dyre og anvendelsen kan kun forsvares i spesielle tilfeller. The impregnating agent used for the production of this layer contains crushed inorganic material and a binder phase which again consists of 5-95% by weight silicic acid sol and 95-5% by weight bentonite, whereby the total solids proportion in the impregnating agent is 2-25% by weight %. The produced material therefore has 1-20% by weight silicic acid sol and 1-15% by weight bentonite, whereby binder clay and feldspar may also be added. Furthermore, fillers can be added. However, such impregnation agents are very expensive and their use can only be justified in special cases.
Fre DE off.skrift 1.919.764 er det kjent en fremgangsmåte til fremstilling av flammesikre isoleringsplater og formlegemer der disse formlegemer behandles med en oppløsning av kiselgur og vannglass for å danne et isolerende dekksjikt. Det som beskrives videre, nemlig at formlegemet under behandlingen med kiselgur-vannglassoppløsningen beveges vibrerende slik at formlegemet dynkes totalt med oppløsningen, gjør det klart at det ikke er tenkt på en belegning som skaloppfylle spesielle krav. Spesielt gir det seg svært sprø bindinger. Fre DE off.skrift 1,919,764 a method is known for the production of flame-resistant insulating boards and molded bodies where these molded bodies are treated with a solution of diatomaceous earth and water glass to form an insulating covering layer. What is described further, namely that during the treatment with the kieselguhr-water glass solution, the molded body is moved vibratingly so that the molded body is completely soaked with the solution, makes it clear that no coating is intended to meet special requirements. In particular, it results in very brittle bonds.
I NO-Patent 140 296 beskrives det en fiberplate, spesielt en takplate, med et belegg bestående av et adhesivpreparat som forhindrer inntregning av flytende bitumen til det indre av isolasjonen ved tetting av tak. Dette belegg må samtidig være ubrennbart, ikke angripe fibrene som utgjør fiberplaten, ikke bli angrepet av fuktighet og må videre bibeholde sin motstands-evne og tillate, i det minste i en viss grad, å kunne bli be-trådd. NO-Patent 140 296 describes a fibreboard, in particular a roof board, with a coating consisting of an adhesive preparation which prevents the penetration of liquid bitumen into the interior of the insulation when sealing a roof. This coating must at the same time be non-combustible, not attack the fibers that make up the fiberboard, not be attacked by moisture and must also retain its resistance and allow, at least to a certain extent, to be walked on.
Formålet med foreliggende oppfinnelse er å oppnå en mineralfiberplate som på en side er dekket med en metallfolie, festet ved hjelp av et uforbrennbart bindemiddel som ikke angriper fibrene, som tjener som armatur for folien, og som ikke irri-terer arbeidernes hud. The purpose of the present invention is to achieve a mineral fiber plate which is covered on one side with a metal foil, fixed by means of a non-combustible binder which does not attack the fibers, which serves as an armature for the foil, and which does not irritate the workers' skin.

Ved anvendelse ifølge foreliggende oppfinnelse av det nedenfor When using the following according to the present invention
beskrevne adhesiv frembringes det således en mineralfiberplate, anvendbar som isolasjonsplate, og som er kasjert med en metallfolie, fortrinnsvis en aluminiumsfolie som tillater at følgende krav oppfylles: Platen skal ikke være brennbar, d.v.s. den skal med henblikk på ikke-brennbarhet, ligge minst en klasse høyere enn de vanlige og ved hjelp av et organisk klebemiddel kasjerte plater. Videre skal klebestoffer for forbindelse mel-lom mineralfiberplaten og metallfolien ikke angripe fibrene og/eller disses binding. described adhesive, a mineral fiber plate is thus produced, usable as an insulation plate, and which is lined with a metal foil, preferably an aluminum foil, which allows the following requirements to be met: The plate must not be flammable, i.e. in terms of non-combustibility, it must be at least one class higher than the usual sheets laminated with an organic adhesive. Furthermore, adhesives for the connection between the mineral fiber board and the metal foil must not attack the fibers and/or their bonding.
Klebestoffet skal heller ikke ha noen ugunstig innvirkning på metallfolien som anvendes til kasjering, skal altså ikke virke korroderende på denne eller lokalt gjøre den sprø eller på annen måte innvirke ugunstig på den. The adhesive must also not have any adverse effect on the metal foil used for casing, i.e. must not have a corrosive effect on it or locally make it brittle or have an adverse effect on it in any other way.
Videre skal det anvendte klebestoff være lett påførbart. Furthermore, the adhesive used must be easy to apply.
De angitte krav medfører visse vanskeligheter da man må passe på at oppfyllelsen av et krav ikke utelukker oppfyllelsen av et annet. The specified requirements entail certain difficulties as care must be taken that the fulfillment of one requirement does not preclude the fulfillment of another.
I henhold til det ovenfor anførte angår oppfinnelsen således anvendelse av et adhesiv bestående av vannglass med en tilsetning i mest mulig finfordelt form av leiremineralske stoffer med sammensetning i vekt-%: In accordance with the above, the invention thus relates to the use of an adhesive consisting of water glass with an addition in the most finely divided form of clay mineral substances with a composition in % by weight:
83 til 95% vannglass med et faststoffinnhold på 29 - 83 to 95% water glass with a solids content of 29 -
3 5 vekt-%, 3 5% by weight,
4 til 16% leiremineralske stoffer, 4 to 16% clay minerals,
1 til 5% oksyder av jordalkalimetaller eller av sink og/eller oksyd eller hydroksyd av aluminium, 1 to 5% oxides of alkaline earth metals or of zinc and/or oxide or hydroxide of aluminium,
0 til 5% pigmenter 0 to 5% pigments
i en etter påføringsteknikken tilpasset fortynning med vann for festing av en metallfolie til en mineralfiberplate. in a dilution with water adapted to the application technique for attaching a metal foil to a mineral fiber board.
Som leiremineralske stoffer egner seg spesielt kaolin, leire og lignende, talkum samt blandinger av disse. Kaolin, clay and the like, talc and mixtures of these are particularly suitable as clay mineral substances.
Anvendes det pigmenter velges fortrinnsvis Fe^ O-^ »FeO (OH) , TiC^, Cr203. If pigments are used, Fe^O-^ »FeO (OH) , TiC^, Cr 2 O 3 are preferably chosen.
For ytterligere reduksjon av sprøheten kan til dette formål i og for seg kjente stoffer slik som fosfat eller borat av 1-3 verdige metaller anvendes i en mengde på opptil 5% i oppløst henholdsvis finfordelt form. To further reduce brittleness, for this purpose substances known in and of themselves such as phosphate or borate of 1-3 valuable metals can be used in an amount of up to 5% in dissolved or finely divided form.
Kravet med henblikk på at ikke-brennbarheten for en slik plate skal forandres minst med en klasse, oppfylles ved anvendelsen av utelukkende mineralske bestanddeler. The requirement for the non-combustibility of such a plate to be changed by at least one class is met by the use of exclusively mineral components.
Ved valget av tilsetninger til vannglass, disse prosentuale andeler og spesielt finheten for tilsetningsstoffene er det mulig å fremstille en sammenhengende film som holder seg ved lagring. Det finner ikke sted noe korroderende angrep på metallfolien. By choosing the additives for water glass, these percentages and especially the fineness of the additives, it is possible to produce a coherent film that holds up during storage. No corrosive attack takes place on the metal foil.
Ved valget av mengden av oksyder av jordalkalimetaller eller sink, oksyder eller hydroksyder av aluminium innen de angitte grenser, oppnår man at faren for at klebemidlet skal bli sprøtt, er meget liten. By choosing the amount of oxides of alkaline earth metals or zinc, oxides or hydroxides of aluminum within the specified limits, it is achieved that the danger of the adhesive becoming brittle is very small.
Tilsetningen av leiremineralske stoffer sikrer i tillegg til dett at det ifølge oppfinnelsen anvendte klebemiddel praktisk talt ikke kan angripe fibrene og/eller disses binding. The addition of clay mineral substances also ensures that the adhesive used according to the invention practically cannot attack the fibers and/or their bonding.
Av spesiell fordel er at tilsetningene av leiremineralske stoffer og pigmenter kan supplere hverandre gjensidig eller erstatte hverandre og at det er sikret at klebestoffet forblir elastisk og bøyelig ved den øvre begrensning av stoffene som frembringer vannuømfintlighet. Derved er det av spesiell be-tydning å overholde tørkingsgraden i det henseende at det tørkes under de for reaksjonen av herderen nødvendige betingelser. Of particular advantage is that the additions of clay mineral substances and pigments can complement each other mutually or replace each other and that it is ensured that the adhesive remains elastic and flexible at the upper limit of the substances that produce water insensitivity. Thereby, it is of particular importance to comply with the degree of drying in that it is dried under the conditions necessary for the reaction of the hardener.
Klebestoffet som anvendes ifølge oppfinnelsen, kan uten videre fortynnes ved tilsetning av vann på grunn av at fyllstoffet i meget finfordelt tilstand og det hele kan således gjøres lett påførbart. The adhesive used according to the invention can be easily diluted by adding water because the filler is in a very finely divided state and the whole can thus be easily applied.
Da klebestoffet som anvendes ifølge oppfinnelsen ikke bare er ukorroderende over metallet, men også forsterker og armerer dette, kan metallfolien velges relativt tynn, noe som fører til en innsparing av foliemateriale. As the adhesive used according to the invention is not only non-corrosive to the metal, but also reinforces and reinforces it, the metal foil can be chosen relatively thin, which leads to a saving of foil material.
Påføring av kleberen kan skje over hele platen hvorved det oppnås en fasthetsøking for metallfolien. Application of the adhesive can take place over the entire plate, whereby an increase in the strength of the metal foil is achieved.
