Description

Oppfinnelsen vedrører et brannmotstandsdyktig og støy-isolerende laminert plateelement med i det minste ett lag som innbefatter et fiberforsterket uorganisk bindemiddel. The invention relates to a fire-resistant and noise-insulating laminated plate element with at least one layer that includes a fiber-reinforced inorganic binder.

Plateelementer av denne typer brukes for mange formålPlate elements of this type are used for many purposes

som skillevegger i bygninger, som lugarskott o.l., og egner seg meget godt for bruk i bygningsbransjen og ombord i skip. as partitions in buildings, as cabin bulkheads etc., and is very suitable for use in the construction industry and on board ships.

Plateelementene må nødvendigvis ha en viss tykkelse slikThe plate elements must necessarily have a certain thickness like this

at de' får den nødvendige brannmotstandsevne som kreves for de forskjellige brannklasser. Dette betyr at tykkelsen vanligvis vil ligge mellom 10 - 30 mm, og plateelementer med slike tykkelser vil være stive og selvbærende. that they get the necessary fire resistance required for the different fire classes. This means that the thickness will usually lie between 10 - 30 mm, and plate elements with such thicknesses will be rigid and self-supporting.

Det er imidlertid ofte, særlig når det dreier seg om lugarskott, viktig at vekten og derfor også tykkelsen er så liten som mulig, samtidig som plateelementet tilfredsstiller de oppstilte krav. However, it is often important, especially when it comes to cabin bulkheads, that the weight and therefore also the thickness is as small as possible, while at the same time that the plate element satisfies the stated requirements.

Plateelementer av den type det her er tale om har i det minste et lag som innbefatter et uorganisk bindemiddel så som f.eks. semenet, gips, kalk eller kalkkisel med diverse fiberforsterkninger i form av organiske eller uorganske fibre eller en blanding av forskjellige fibre. Plate elements of the type in question here have at least one layer which includes an inorganic binder such as e.g. cement, gypsum, lime or liming silica with various fiber reinforcements in the form of organic or inorganic fibers or a mixture of different fibers.

De kjente plateelementer har imidlertid den ulempe atHowever, the known plate elements have the disadvantage that

deres støyisolasjonsevne ofte er utilstrekkelig til å tilfredsstille spesifikasjonene eller en anvendt standard, og de er util-fredsstillende når det gjelser kontrollen av støyutstråling som skyldes mekaniske vibrasjoner. Støyreduksjonen kan naturligvis bedres ved å øke tykkelsen av plateelementet eller ved å bruke avstandsplasserte plateelementer. Et stort antall forskjellige sammensatte plateelementer er kjent for dette formål. their noise isolation capability is often insufficient to satisfy the specifications or an applied standard, and they are unsatisfactory when it comes to the control of noise emissions due to mechanical vibrations. The noise reduction can of course be improved by increasing the thickness of the plate element or by using spaced plate elements. A large number of different composite plate elements are known for this purpose.

Sammensatte plateelementer er dyre og videre er det uøkonomisk å øke tykkelsen til de .laminerte plateelementer. Composite plate elements are expensive and furthermore it is uneconomical to increase the thickness of the laminated plate elements.

Ifølge foreliggende oppfinnelse tilveiebringes det et brannmotstandsdyktig og støyisolerende laminert plateelement som har i det minste tre lag, idet i det minste ett av de ytre av de tre lag innbefatter et fiberforsterket uorganisk bindemiddel og det sentrale av de tre lag er et adhesiv som utgjøres av et viskoelastisk eller elastisk polymert materiale med en tykkelse •-. som overskrider den dimensjon som er nødvendig for å binde de tre lag sammen. According to the present invention, a fire-resistant and noise-insulating laminated plate element is provided which has at least three layers, at least one of the outer of the three layers includes a fiber-reinforced inorganic binder and the central of the three layers is an adhesive which consists of a viscoelastic or elastic polymeric material with a thickness •-. which exceeds the dimension necessary to bind the three layers together.

Viskoelastiske og elastiske lag har en markert dempnings-virkning, f.eks. anvendt i forbindelse med betongvegger eller --gulv eller andre konstruksjonsdeler i bygninger, og det er kjent å benytte viskoelastiske lag i form av lag lagt inn mellom to konstruksjonsplater. Ifølge foreliggende oppfinnelse utgjør imidlertid adhesivet som holder lagene sammen et viskoelastisk .. eller elastisk lag. Viscoelastic and elastic layers have a marked damping effect, e.g. used in connection with concrete walls or floors or other construction parts in buildings, and it is known to use viscoelastic layers in the form of layers inserted between two construction plates. According to the present invention, however, the adhesive that holds the layers together forms a viscoelastic .. or elastic layer.

Et av lagene i plateelementet, enten ett av de ytre avOne of the layers in the plate element, either one of the outer ones

de tre lag eller et lag som er- bundet til et slikt lag, kan være et dekorativt ark, f.eks. et dekorativt plastlaminat. the three layers or a layer which is bound to such a layer can be a decorative sheet, e.g. a decorative plastic laminate.

I en mulig utførelse kan adhesivet som utgjør det viskoelastiske eller det elasktiske lag være et skumadhesiv. In one possible embodiment, the adhesive constituting the viscoelastic or the elastic layer can be a foam adhesive.

Dette er særlig fordelaktig når overflatene på begge sider av adhesivet er rue. This is particularly advantageous when the surfaces on both sides of the adhesive are rough.

De fiberforsterkede uorgansiské bindemiddellag kan frem-stilles på samme måte som kjent i forbindelse med asbestsement-plater og ved hjelp av samme type maskiner som benyttes i asbest-sement- industrien. Slike plater har ofte en ru overflate, hvilket betyr at de må sandblåses for at man skal få en egnet overflate, f.eks. når man skal legge på en dekorativ laminat. Ved bruk av et skumadhesiv kan man unngå den vanskelige og støvfrembringende sandblåsing av overflatene, idet skumadhesivet er i stand til å The fiber-reinforced inorganic binder layers can be produced in the same way as is known in connection with asbestos-cement sheets and with the help of the same type of machines used in the asbestos-cement industry. Such plates often have a rough surface, which means that they must be sandblasted in order to obtain a suitable surface, e.g. when laying on a decorative laminate. By using a foam adhesive, the difficult and dust-producing sandblasting of the surfaces can be avoided, as the foam adhesive is able to

gi den ønskede sterkere sammenbinding.give the desired stronger bond.

Adhesivet kan i noen tilfeller tilveiebringes ved at en separat folie limes til lagene som skal sammenbindes, under ut-nyttelse av et viskoelastisk eller elastisk eller elastisk materiale. In some cases, the adhesive can be provided by gluing a separate foil to the layers to be joined, using a viscoelastic or elastic or elastic material.

Adhesivet kan alternativt være en termoherdende eller en termoplastisk folie som bindes til de hosliggende lag ved hjelp av varmebehandling. Alternatively, the adhesive can be a thermosetting or a thermoplastic film which is bonded to the adjacent layers by means of heat treatment.

Fortrinnsvis inneholder lagene med fiberforsterket uorganisk bindemiddel kiselholdig materiale så som f.eks. diatoméjord, kalkhydrat og kalksement så vel som forsterkningsfibre og eventuelt fyllmateriale. Slike materialer egner seg med hensyn til oppnåelsen av den nødvendige brannmotståndsevne. Foretrukne fibre er E-glassfibre, mineralfibre og cellulosefibre. Preferably, the layers with fiber-reinforced inorganic binder contain siliceous material such as e.g. diatomaceous earth, lime hydrate and lime cement as well as reinforcing fibers and any filler material. Such materials are suitable in terms of achieving the required fire resistance. Preferred fibers are E-glass fibers, mineral fibers and cellulose fibers.

Som nevnt kan plateelementet på hver side ha et lag avAs mentioned, the plate element on each side can have a layer of

et dekorativt laminat av plast eller et annet egnet materiale, hvorav i det minste ett er forbundet med det underliggende lag ved hjelp av et adhesiv som utgjør en viskoelastisk eller elastisk polymer-materiale-folie Et plateelement av denne type ér i stand til å tilfredsstille de fleste brannvernkrav, og man kan oppnå forbedringer med hensyn til støyreduseringen på 5 - 8 dB ved bruk av et viskoelastisk eller elastisk polymert adhesiv. Man har også observert en markert redusering av lydutstrålingsgraden, som følge av at plateelementet har en lav skjærspenning. a decorative laminate of plastic or another suitable material, at least one of which is connected to the underlying layer by means of an adhesive which forms a viscoelastic or elastic polymer-material-foil A plate element of this type is able to satisfy the most fire protection requirements, and improvements in noise reduction of 5 - 8 dB can be achieved by using a viscoelastic or elastic polymeric adhesive. A marked reduction in the degree of sound emission has also been observed, as a result of the plate element having a low shear stress.

Adhesivet kan være en polyuretan, polyvinylacetat ellerThe adhesive can be a polyurethane, polyvinyl acetate or

et annet egnet polymert materiale som kan tilformes som en folie, fordelaktig med en tykkelse mellom 0,2 og 0,5 mm og kan innbefatte et inert fyllmateriale eller et annet modifiserende materiale. another suitable polymeric material which can be formed as a foil, advantageously with a thickness between 0.2 and 0.5 mm and which may include an inert filler material or another modifying material.

Oppfinnelsen kan utføres i praksis på forskjellige måter, og i det etterfølgende skal et praktisk utførelseseksempel beskrives. The invention can be implemented in practice in various ways, and in what follows a practical implementation example will be described.

Plateelementet har 7 lag, nemlig to ytre dekorative lag som er av en tykkelse på 2,5 mm og er tilformet av et dekorativt plastlaminat av den tyos som benyttes for møbler og vegger, to indre lag som hver dannes av en sementplate med en tykkelse på 7 mm og forsterket med E-glassfibre, og tre adhesivlag som veksler med de andre fire lag, slik at det dannes et godt sammenbundet laminert produkt. Hvert adhesivlag har en tilnærmet tykkelse på 3,5 mm, The plate element has 7 layers, namely two outer decorative layers which are of a thickness of 2.5 mm and are formed from a decorative plastic laminate of the tyos used for furniture and walls, two inner layers which are each formed by a cement board with a thickness of 7 mm and reinforced with E-glass fibres, and three adhesive layers that alternate with the other four layers, so that a well-connected laminated product is formed. Each adhesive layer has an approximate thickness of 3.5 mm,

dvs. en tykkelse som er betydelig større enn den som er nødvendig bare for å gi adhesjon, og laget består av et skummet polyuretan-materiale som er elastisk eller viskoelastisk. i.e., a thickness significantly greater than that required just to provide adhesion, and the layer consists of a foamed polyurethane material which is elastic or viscoelastic.
