Description

I de senere år har man begynt å utforme de innvendige tak i hus In recent years, people have started to design the internal ceilings of houses

på enklere måte enn tidligere. Istedenfor gipstak eller takkledninger som er oppspent på en vevnad eller papp, spenner man nå opp en hvit, mattert PVC-folie som himling, spesielt i boliger. Dette finner sted enten mekanisk, ofte manuelt, eller ved at folien oppsettes i svellet tilstand og planheten oppnås ved at folien krymper ved fjerning av foliens svellemiddel. Den siste fremgangsmåte har vist seg å innebære store fordeler for oppnåelse av en varig planhet av den på denne måte oppsatte himling. in an easier way than before. Instead of plaster ceilings or ceiling cables that are stretched on a fabric or cardboard, a white, matt PVC foil is now stretched as a ceiling, especially in homes. This takes place either mechanically, often manually, or by the foil being set up in a swollen state and the flatness achieved by the foil shrinking when the foil's swelling agent is removed. The last method has been shown to entail great advantages for achieving a permanent flatness of the ceiling set up in this way.

Disse innvendige tak eller kledninger som består av PVC eller These internal ceilings or coverings which consist of PVC or

en annen plast, anses riktignok som relativt brannsikre, men det hender allikevel at folien ved brann eller branntilløp brenner istykker og faller ned som mer eller mindre store flak og herunder frembringer skader, spesielt brannskader på personer som befinner seg i rommet i slike tilfelle. Også ved anvendelse av foliene som veggkledning kan slike risikoer ved brann oppstå. another plastic, is admittedly considered relatively fireproof, but it still happens that in the event of a fire or fire, the foil burns to pieces and falls down as more or less large flakes and thereby causes damage, especially burn damage to people who are in the room in such a case. Such risks in the event of fire can also arise when the foils are used as wall cladding.

Den foreliggende oppfinnelse tar sikte på å eliminere de sistnevnte ulemper ved f.eks. takkledninger, veggkledninger eller lignende av plast- eller gummifolier, og folien ifølge oppfinnelsen er hoved-sakelig karakterisert ved at den er forsynt med en armering av ikke brennbart eller vanskelig antennelig materiale som tillater en viss strekning av folien ved oppsettingen, og som ved brann, resp. ved forkulling av plasten, danner et bærende skjelett eller skall som motvirker eller forhindrer nedfall av brennende eller glødende folie-partier. Armeringsmaterialet, som passende består av relativt korte fibre eller fnugg med liten overflate, kan enten støpes inn i plasten ved foliens fremstilling eller påføres folien som et utenpåliggende skikt eller belegg etter foliens fremstilling. I sistnevnte tilfelle blir skiktet forankret ved hjelp av en bindemiddeloppløsning som passende består av samme materiale som i selve folien. The present invention aims to eliminate the latter disadvantages of e.g. roof cables, wall coverings or the like made of plastic or rubber foils, and the foil according to the invention is mainly characterized by the fact that it is provided with a reinforcement of non-flammable or difficult-to-ignite material which allows a certain stretch of the foil during installation, and as in the event of a fire, respectively when the plastic is charred, forms a supporting skeleton or shell that counteracts or prevents the fall of burning or glowing foil parts. The reinforcement material, which suitably consists of relatively short fibers or fluff with a small surface area, can either be molded into the plastic during the foil's manufacture or applied to the foil as an external layer or coating after the foil's manufacture. In the latter case, the layer is anchored by means of a binder solution which conveniently consists of the same material as in the foil itself.

Som armeringsmateriale er særlig fibre eller fiberknipper, resp. Reinforcing material is particularly fibers or fiber bundles, resp.

fnugg av glass, metall, asbest, grafitt, aluminiumoksyd, mineralull flakes of glass, metal, asbestos, graphite, aluminum oxide, mineral wool

xOg lignende egnet. Piberlengdene, resp. størrelsen av fnuggenes overflate, bestemmer i en viss grad den mengde armeringsmateris.le som kan innblandes i eller påføres folien. Gode resultater er således opp-nådd ved anvendelse av følgende størrelsesforhold ved anvendelse av fibre eller fiberknipper av de ovennevnte materialer: xAnd similarly suitable. The pipe lengths, resp. the size of the flakes' surface determines to a certain extent the amount of reinforcement material that can be mixed into or applied to the foil. Good results have thus been achieved by using the following size ratio when using fibers or fiber bundles of the above-mentioned materials:

0,5 - 10% ved fiberlengder mellom 50 og 100 mm, 0.5 - 10% for fiber lengths between 50 and 100 mm,

10 - 25% ved fiberlengder mellom 15 og 50 mm, 10 - 25% for fiber lengths between 15 and 50 mm,

25 - 50$ ved fiberlengder mellom 5 og 15 mm, 25 - 50$ for fiber lengths between 5 and 15 mm,

50 - 100$ ved fiberlengder mellom 1 og 5 mm og 50 - 100$ for fiber lengths between 1 and 5 mm and

100 - 200$ ved fiberlengder på under 1 mm. 100 - 200$ for fiber lengths of less than 1 mm.

Lignende forhold gjelder ved anvendelse av fnuggformet armeringsmateriale. Por oppnåelse av visse virkninger kan det være hensiktsmessig å blande forskjellige materialer med ulike, fiberlengder og/eller fnuggformet materiale. De angitte fiberlengder er ikke ment å skulle begrense oppfinnelsen, men tjener bare som anbefaling. Similar conditions apply when using fluff-shaped reinforcement material. In order to achieve certain effects, it may be appropriate to mix different materials with different fiber lengths and/or fluff-shaped material. The specified fiber lengths are not intended to limit the invention, but only serve as a recommendation.

Ved anvendelse av det nå foreslåtte armeringsmateriale til armering av plast- eller gummifolier, spesielt til oppsetting av himlinger og som veggkledning, oppnås det at plasten ved brann forkulles og When using the now proposed reinforcing material for reinforcing plastic or rubber foils, especially for erecting ceilings and as wall cladding, it is achieved that the plastic chars in the event of a fire and

danner en enhet med armeringsmaterialet, som forblir uendret og danner et bærende skjelett for den forkullede plastfolie og derved forhindrer at den brennende eller glødende folie eller partier av denne faller ned. forms a unit with the reinforcing material, which remains unchanged and forms a supporting skeleton for the charred plastic foil and thereby prevents the burning or glowing foil or parts thereof from falling down.

Den ovenfor foreslåtte armering har vist seg å kunne benyttes ikke bare ved myke folier som spennes opp ved mekanisk strekking, men også ved anvendelse av folier som er svellet før oppsetting av him-lingen. Dette er bemerkelsesverdig, idet selve armeringen som sådan jo ikke er tøyelig med hensyn til de fibre eller fiberknipper som inngår i armeringen. Dette er en uventet virkning som er meget verdifull, idet anvendelsen av svellede plastfolier ved oppsetting av himlinger medfører helt spesielle fordeler og gir et meget gunstig sluttresultat, nærmere bestemt plane og glatte himlinger som ikke er tilbøyelige til å henge ned etter en viss tid. The reinforcement proposed above has proven to be usable not only with soft foils that are stretched by mechanical stretching, but also with the use of foils that have been swollen before setting up the ceiling. This is remarkable, since the reinforcement itself is not stretchable as such with respect to the fibers or fiber bundles that are part of the reinforcement. This is an unexpected effect that is very valuable, as the use of swollen plastic foils when setting up ceilings brings very special advantages and gives a very favorable end result, more specifically flat and smooth ceilings that are not inclined to sag after a certain time.

Ved belegning av plastfoliens overflate med korte fibre og/eller småfnugg (flak) som armering av folien, fås helt spesielle virkninger av en annen art enn ved folier med mattert overflate. I visse tilfelle kan man oppnå lignende resultat ved å kasjere folien med en trikotbane som punkt- og/eller linjeformig forbindes med folien. When coating the surface of the plastic film with short fibers and/or small flakes (flakes) as reinforcement of the film, very special effects of a different kind are obtained than with films with a matte surface. In certain cases, a similar result can be achieved by covering the foil with a tricot web which is connected to the foil in points and/or lines.

Piberbelegningen må naturligvis være tilstrekkelig tett til ved brann å danne det ovennevnte bærende skjelett som kan forhindre nedfall. The pipe coating must of course be sufficiently dense to form the above-mentioned load-bearing skeleton in the event of a fire, which can prevent fallout.

I det etterfølgende skal oppfinnelsen belyses med noen utførelses-eksempler. In what follows, the invention will be illustrated with some design examples.

Eksempel 1 Example 1

I en 25%' s oppløsning av neopren (polykloropren) i toluen inneholdende vulkaniseringsmiddel, stabiliseringsmiddel, pigment og antimonoksyd innblandes 1% glasstråder inneholdende 5 mikrometer tykke glassfibre av 1,5 cm lengde. Blandingen støpes på en endeløs bane som opp-varmes til 100°C slik at oppløsningsmiddelet fordamper og neoprenet vulkaniseres. Deretter tas den dannede folie av fra banen og anvendes etter renskjæring og konfeksjonering ved hjelp av liming som takfolie til innvendig takkledning eller himling. In a 25% solution of neoprene (polychloroprene) in toluene containing vulcanizing agent, stabilizer, pigment and antimony oxide, 1% glass threads containing 5 micrometer thick glass fibers of 1.5 cm length are mixed. The mixture is cast on an endless web which is heated to 100°C so that the solvent evaporates and the neoprene is vulcanised. The formed foil is then removed from the web and used after clean cutting and assembly by means of gluing as roofing foil for internal roof linings or ceilings.

Eksempel 2 Example 2

En PVC-folie inneholdende PVC, mykningsmiddel, pigment, antimonoksyd og stabilisatorer belegges med en 20$'s oppløsning av den samme folie i en blanding av like deler metyletylketon og tetrahydrofuran inneholdende 1,5$ glasstråder av samme art som i Eksempel 1, men med en lengde på 5 mm. A PVC foil containing PVC, plasticizer, pigment, antimony oxide and stabilizers is coated with a 20% solution of the same foil in a mixture of equal parts methyl ethyl ketone and tetrahydrofuran containing 1.5% glass threads of the same type as in Example 1, but with a length of 5 mm.

Eksempel 3 Example 3

En folie av samme art som i eksempel 2 kasjeres med en trikotbane av glassfibre, idet det passes på at limet ikke påføres over hele overflaten, men bare i form av et punkt- og/eller linjemønster. Derved oppnås en større svellbarhet eller tøybarhet av det ferdige produkt, som derfor kan anvendes med større måltoleranser enn om trikotbanen på tidligere kjent måte innleires i folien eller forbindes med denne over hele overflaten slik at tråder som inngår i banen, er fastlåst i folien, noe som ville hindre tøyning av den på denne måte armerte folie. A foil of the same type as in example 2 is coated with a tricot web of glass fibers, taking care that the glue is not applied over the entire surface, but only in the form of a point and/or line pattern. Thereby, a greater swellability or stretchability of the finished product is achieved, which can therefore be used with greater measurement tolerances than if the tricot web is embedded in the foil in the previously known manner or is connected to this over the entire surface so that threads that are part of the web are locked in the foil, which which would prevent stretching of the foil reinforced in this way.

Eksempel 4 Example 4

En bane fremstilt av tråder av ikke myknet homopolymert PVC belegges med en 20$'s oppløsning av PVC inneholdende mykningsmiddel, pigment, antimonoksyd, stabilisatorer og ca. 3$ glasstråder av samme art som i Eksempel 1, men med en lengde på 2 mm. Etterat duken er tørket, svelles den ved anvendelse av etyldiglykol som svellingsmiddel og henges deretter opp som himling og tillates å tørke, slik at den spennes til en plan, glatt overflate. A web made from strands of unplasticized homopolymeric PVC is coated with a 20% solution of PVC containing plasticizer, pigment, antimony oxide, stabilizers and approx. 3$ glass threads of the same type as in Example 1, but with a length of 2 mm. After the cloth is dried, it is swelled using ethyl diglycol as a swelling agent and then suspended as a ceiling and allowed to dry, so that it is tensioned to a flat, smooth surface.

I denne duk virker den av tråder fremstilte PVC-bane ikke som brannbeskyttelsesarmering, men går inn som en del av den svellbare plastfolie som er brannbeskyttelsesarmert med glassfibre. PVC-trådene er nemlig svellbare i omtrent samme grad som en PVC-folie dannet ved stopning. Fordelen ved å anvende en bane av ikke myknede PVC-tråder istedenfor en myknet PVC-folie er at der fås mindre tendens til kald-. flytning, d.v.s. nedhengning av den oppspente himling etter en tids anvendelse av denne. In this cloth, the PVC web made of threads does not act as fire protection reinforcement, but enters as part of the swellable plastic film which is fire protection reinforced with glass fibres. The PVC threads are swellable to approximately the same extent as a PVC foil formed by stuffing. The advantage of using a web of non-softened PVC threads instead of a softened PVC foil is that there is less tendency to cold-. moving, i.e. suspension of the suspended ceiling after a period of use of this.

Som PVC-trådbane kan de fleste typer av trådbaner anvendes. Det As PVC wire web, most types of wire webs can be used. The

er imidlertid særlig hensiktsmessig å anvende en eller annen type av trikotbane, da disse gir jevnere svelling resp. krymping i alle for- however, it is particularly appropriate to use one or another type of tricot track, as these provide more uniform swelling or shrinkage in all forms

skjellige retninger. different directions.

Som trådmateriale istedenfor PVC-trådene i det ovennevnte eksempel As thread material instead of the PVC threads in the above example

kan man også anvende andre fibre som er svellbare i samme type opp-løsningsmiddel som plastfoliematerialet i duken. Således kan man også you can also use other fibers that are swellable in the same type of solvent as the plastic foil material in the cloth. That way you can too

tenke seg å anvende svellbare polyamidtråder, og i dette tilfelle bør foliematerialet være svellbare polyamider, f.eks. slike som fås ved at polyamid 6 eller polyamid 66 behandles i sur oppløsning og varme med en blanding av aldehyd og alkohol. imagine using swellable polyamide threads, and in this case the foil material should be swellable polyamides, e.g. such as are obtained by treating polyamide 6 or polyamide 66 in an acidic solution and heat with a mixture of aldehyde and alcohol.

På samme måte kan man tenke seg baner av spesielle svellbare cellulosefibre, celluloseacetatfibre, fibre av vinylidenklorid- In the same way, one can imagine webs of special swellable cellulose fibers, cellulose acetate fibers, fibers of vinylidene chloride-

kopolymerer, fibre av akrylnitritt-kopolymerer o.s.v. copolymers, fibers of acrylic nitrite copolymers, etc.

Eksempler på egnede plaster eller gummiarter for disse himlinger Examples of suitable plaster or rubber types for these ceilings

er polyvinylklorid og forskjellige kopolymerisater av vinylklorid, polyamider, polyuretaner, polykloroprener (neopren) sulfoklorert polyeten (hypalon), klorkautsjuk m.fl. og blandinger av de ovennevnte polymerer. is polyvinyl chloride and various copolymers of vinyl chloride, polyamides, polyurethanes, polychloroprenes (neoprene), sulphochlorinated polyethylene (hypalon), chlorinated rubber, etc. and mixtures of the above polymers.

Egnede fibermaterialer er glassfibre, metallfibre, asbestfibre, cellulosefibre, mineralullfibre etc. samt tynne glassfnugg av den art som undertiden anvendes til armering av pressmatter. Ved anvendelse av en bane 'som armeringsmateriale må denne være tøybar i alle retninger. Suitable fiber materials are glass fibres, metal fibres, asbestos fibres, cellulose fibres, mineral wool fibres, etc. as well as thin glass flakes of the kind that are sometimes used to reinforce press mats. When using a web as reinforcing material, it must be stretchable in all directions.
