Description

Foreliggende oppfinnelse angår en overflateforsterkning av porøse legemer eller plater bestående av fibre og et herdet bindemiddel, f.eks. minerallfibre og herdet fenolharpiks som danner et delvis elastisk gitter med gjennomgående hulrom mellom fibrene. The present invention relates to a surface reinforcement of porous bodies or plates consisting of fibers and a hardened binder, e.g. mineral fibers and hardened phenolic resin which form a partially elastic lattice with continuous cavities between the fibers.

Det er kjent fra blant annet dansk patent nr. 97863 å forsterke mineralullplater fremstilt av f.eks. glassull, stenull eller slaggull ved påføring av en opp-løsning. De benyttede oppløsningene utfyller imidlertid hulrommene som finnes i de porøse legemene, slik at de er damp- og lufttette. It is known from, among other things, Danish patent no. 97863 to reinforce mineral wool sheets made from e.g. glass wool, rock wool or beaten gold when applying a solution. The solutions used, however, fill the cavities found in the porous bodies, so that they are vapor and air tight.

Isoleringsevnen og lydabsorpsjonsevnen på slike plater blir forringet meget vesentlig. Lukkingen av hulrommene er meget uheldig når de porøse legemene skal benyttes til blant annet utvendig bekledning og isolering av vegger og tak, idet slike legemer i det minste skal være dampdiffusjonsåpne. The insulating capacity and sound absorption capacity of such boards deteriorates very significantly. The closing of the cavities is very unfortunate when the porous bodies are to be used for external cladding and insulation of walls and ceilings, as such bodies must at least be open to vapor diffusion.

Hensikten med foreliggende oppfinnelse er å unngå ovennevnte ulemper,og dette oppnås ved det som angis.i krav 1 . The purpose of the present invention is to avoid the above-mentioned disadvantages, and this is achieved by what is stated in claim 1.

Ved hjelp av trekkene i underkravene fåes et produkt med optimale egenskaper og tørketid. With the help of the features in the sub-claims, a product with optimal properties and drying time is obtained.

De forsterkede porøse legemene ifølge oppfinnelsen er godt egnet til bruk ved utvendig bekledning og isolering av bygninger. Slike bekledninger skal ha en hard overflate, være dampdiffusjonsåpne samtidig med at de har gode trykk-, trekk- og bøyebruddstyrker. Legemene skal dessuten være billige å fremstille og montere. Legemene ifølge oppfinnelsen har disse egenskaper, idet de kan settes opp på eksisterende vegger med lim eller med mekanisk fastgjøring. De har en hard overflate og behøver således ingen ytterligere overflatebehandling. Ønskes imidlertid en annen farge eller struktur på overflaten, er den velegnet til påføring av slike materialer uten ytterligere foranstaltninger, idet'legemenes overflater er velegnet til påføring av alminnelige fasademalinger og -puss. The reinforced porous bodies according to the invention are well suited for use in exterior cladding and insulation of buildings. Such coverings must have a hard surface, be open to vapor diffusion and at the same time have good compressive, tensile and flexural strength. The bodies must also be cheap to manufacture and assemble. The bodies according to the invention have these properties, as they can be set up on existing walls with glue or with mechanical fastening. They have a hard surface and thus do not need any further surface treatment. However, if a different color or texture is desired on the surface, it is suitable for applying such materials without further measures, as the bodies' surfaces are suitable for applying ordinary facade paints and plasters.

Utvendig bekledning og isolering av bygninger med legemer ifølge oppfinnelsen kan gjøres for ca. halv pris av hva det koster med tradisjonelle metoder, som f.eks. beskrevet i EPC-patentansøkning nr. 17969. Videre blir bekledningen ifølge oppfinnelsen vesentlig lettere enn de kjente bekledningssystemer. External cladding and insulation of buildings with bodies according to the invention can be done for approx. half the price of what it costs with traditional methods, such as e.g. described in EPC patent application no. 17969. Furthermore, the cladding according to the invention is significantly lighter than the known cladding systems.

Oppfinnelsen skal i det følgende forklares nærmere under henvisning til tegningen. Fig. 1 viser skjematisk de på forhånd sammen-bundne fibre uten fyllmasse. Fig. 2 viser de samme fibre med flytende fyllmasse, og The invention will be explained in more detail below with reference to the drawing. Fig. 1 schematically shows the pre-bonded fibers without filler. Fig. 2 shows the same fibers with liquid filler, and

fig. 3 viser de samme fibre med tørket fyllmasse. fig. 3 shows the same fibers with dried filler.

Figurene viser fibrene i et plan, men i de porøse legemene danner de rommelige gittere. The figures show the fibers in a plane, but in the porous bodies they form spacious lattices.

I fig. 1 er det skjematisk og meget forstørret vist noen fibre 1 i et lite utsnitt av en porøs mineralull-plate. Fibrene 1 er sammenholdt til hverandre i kryss-ningspunkter 2 med et bindemiddel, f.eks. herdet fenolharpiks, slik at det dannes hulrom 3. In fig. 1 shows schematically and greatly enlarged some fibers 1 in a small section of a porous mineral wool sheet. The fibers 1 are held together at crossing points 2 with a binder, e.g. hardened phenolic resin, so that cavities are formed 3.

I fig. 2 vises det samme som i fig. 1, men det er nå tilført en flytende fyllmasse som skjematisk er vist som små prikker. Den flytende fyllmassen utfyller hulrommene 3. Den flytende fyllmassen er tilsatt et fordampbart oppløsningsmiddel. Når oppløsningsmiddelet for-damper, trekker fyllmassen seg sammen omkring fibrene 1, som vist skjematisk i fig. 3, og legger seg som en sammen-hengende forsterkende hinne eller film 4 og trekker seg nesten helt vekk fra hulrommene 3, så de bli åpne og innbyrdes forbundet igjen, hvorved mineralullplaten blir damp-diffusjons- og luftåpen igjen. Det skjer en fysisk tørking med et stort volumsvinn. Den tørkede fyllmassen-legger seg som en forsterkning omkring de enkelte fibre 1 og kryssningspunktene 2. Den tørkede fyllmassen 4 støtter derved de enkelte fibrene 1 slik at de støttes under trykkpåvirkning, hvorved fibrene 1 ikke kan bøye ut og knekke. Samtidig forsterkes kryssningspunktene slik at strekkstyrken likeledes økes. Hele mineralullplatens trykk-strekk- og bøyestyrke er således økt vesentlig, samtidig med at overflaten er blitt hard uten at platens porøsitet er endret nevneverdig. Noen av fibrene kan ligge tett sammen, slik at de danner såkalte fiberbunter. Fyllmassen vil da legge seg omkring fiberbuntene. Den flytende fyllmassen som innføres i den porøse mineralull-flaten kan være en emulsjon eller en oppløsning. Fyllmassen kan være f-, eks. en kautsjuk, polyvinylacetat, polyvinylklorid/vinyleter eller copolymerisater, som kan være av styren/butadien eller vinyltoluen/akrylester. Fyllmassen kan være oppløst i et oppløsningsmiddel,f.eks. aromatiske oppløsninger eller forbindelser, alifater, estere eller ketoner. Av aromatiske forbindelser kan nevnes xylol og toluol. In fig. 2 shows the same as in fig. 1, but a liquid filler has now been added which is schematically shown as small dots. The liquid filling mass fills the cavities 3. The liquid filling mass has added an evaporable solvent. When the solvent evaporates, the filling mass contracts around the fibers 1, as shown schematically in fig. 3, and lays down as a continuous reinforcing membrane or film 4 and pulls almost completely away from the cavities 3, so that they become open and interconnected again, whereby the mineral wool sheet becomes open to steam diffusion and air again. A physical drying takes place with a large loss of volume. The dried filler is placed as a reinforcement around the individual fibers 1 and the crossing points 2. The dried filler 4 thereby supports the individual fibers 1 so that they are supported under pressure, whereby the fibers 1 cannot bend out and break. At the same time, the crossing points are reinforced so that the tensile strength is also increased. The compressive-tensile and bending strength of the entire mineral wool board has thus been significantly increased, while at the same time the surface has become hard without the board's porosity having changed appreciably. Some of the fibers can lie close together, so that they form so-called fiber bundles. The filler will then settle around the fiber bundles. The liquid filler that is introduced into the porous mineral wool surface can be an emulsion or a solution. The filler can be f-, e.g. a rubber, polyvinyl acetate, polyvinyl chloride/vinyl ether or copolymers, which may be of styrene/butadiene or vinyl toluene/acrylic ester. The filler can be dissolved in a solvent, e.g. aromatic solutions or compounds, aliphatics, esters or ketones. Aromatic compounds include xylol and toluene.

Til fyllmassen kan også tilsettes forskjellige materialer, som forbedrer det forsterkede produkts egenskaper. Det kan f.eks. tilsettes fargestoffer, brann-hemmende stoffer og bløtgjørende stoffer. Hvis det som bløtgjørende stoff tilsettes klorerende parafintyper, elimineres revnedannelse ved svinn. Den flytende fyllmassen kan påføres ved sprøyting med en lakkeringsmaskin eller platen kan dyppes i et kar som inneholder den flytende fyllmasse. Avhengig av hvor mye oppløsningsmiddel som tilsettes, kan inntrengningshastighet, -dybde og porøsitet m.v. reguleres. Den flytende fyllmassen kan bringes til å trenge gjennom hele platen, hvis dette er ønskelig. Fyllmassen kan inneholde opptil nesten 100% fordampbart opp-løsningsmiddel . Different materials can also be added to the filling mass, which improve the properties of the reinforced product. It can e.g. dyes, fire-retardant substances and softening substances are added. If chlorinating paraffin types are added as a softening agent, cracking due to shrinkage is eliminated. The liquid filler can be applied by spraying with a painting machine or the panel can be dipped in a vessel containing the liquid filler. Depending on how much solvent is added, penetration speed, depth and porosity etc. regulated. The liquid filler can be made to penetrate the entire plate, if this is desired. The filler can contain up to almost 100% volatile solvent.

Den forsterkede mineralullplaten som kan ha for-skjellig romvekt og tykkelse er naturligvis også velegnet til bruk andre steder enn nevnt ovenfor. The reinforced mineral wool board, which can have different bulk density and thickness, is of course also suitable for use in other places than mentioned above.

Den beskrevne idé er ikke begrenset til forsterkning av mineralull, men kan anvendes til forsterkning av alle porøse legemer som er oppbygget av fibre, f.eks. cellulosefibre eller treull. The described idea is not limited to the reinforcement of mineral wool, but can be used for the reinforcement of all porous bodies which are made up of fibres, e.g. cellulose fibers or wood wool.

Når mineralullplatene skal benyttes til utvendig bekledning, vil pålegging av den flytende fyllmassen i en mengde på under 51 g/m 2 normalt være tilstrekkelig og en inntrengning på under 10 mm være nok. When the mineral wool sheets are to be used for exterior cladding, application of the liquid filler in an amount of less than 51 g/m 2 will normally be sufficient and a penetration of less than 10 mm will be enough.
