Description
Sammensatt plate og fremgangsmåte for fremstilling Composite plate and method of manufacture
av denne. of this one.
Foreliggende oppfinnelse angår en sammensatt plate som består av The present invention relates to a composite plate which consists of
en kjerne av varmeisolerende material mellom■ytterlag av metall. a core of heat-insulating material between ■outer layers of metal.
Videre gjelder oppfinnelsen også en fremgangsmåte for fremstilling av sådanne plater. Furthermore, the invention also relates to a method for producing such plates.
Sådanne■sammensatte plater "har den ulempe at metallsjiktene ved-stor temperaturforskjell mellom platens to sider utvider seg i forskjellig grad således at platen vil -krummes på grunn av dette. Dette er særskilt ved store plater som anvendes i bygningsindustrien til stor ulempe. Således kan eksempelvis, en sådan sterk deformering ikke godtas ved dorer, da dette vil odelegge dorens avstegningsevne og innvirke forstyrrende på låsemekanismens funksjon. Such ■composite plates "have the disadvantage that the metal layers, when there is a large temperature difference between the two sides of the plate, expand to different degrees, so that the plate will -curve because of this. This is especially a big disadvantage with large plates used in the building industry. Thus, for example, such a strong deformation is not accepted for mandrels, as this will destroy the mandrel's ability to detach and have a disruptive effect on the function of the locking mechanism.
Fra NO-PS nr. 110. ^15. er det kjent en sammensatt plate som er slik utformet at den under fremstillingen ikke utsettes for buling eller krumning som folge av varme- eller kuldepåvirkning og derav folgende forskjellig utvidelse eller .sammentrekking i de respektive sjikt.' ....... From NO-PS No. 110. ^15. a composite plate is known which is designed in such a way that during manufacture it is not exposed to bulging or curvature as a result of heat or cold and the consequent different expansion or contraction in the respective layers. .......
For å unngå en slik deformasjon av platen under fremstillingen velges det f"or de' enkelte-sjikt materialer med bestemte tykkelser., og styrkeforhold. Ved storre temperaturforskjeller mellom utside, og innside av en plate som beskrevet i det nevnte patenskrift vil imidlertid metallsjiktene på de respektive sider-av platen strekke seg-ulike meget slik at platen får en buling eller forkastning. In order to avoid such deformation of the plate during manufacture, materials with specific thicknesses and strength ratios are chosen for the individual layers. However, in the case of larger temperature differences between the outside and the inside of a plate as described in the aforementioned patent, the metal layers on the respective sides of the plate stretch very differently so that the plate gets a bulge or fault.
Foreliggende oppfinnelse har til -hensikt å.overvinne denne ulempe ved sammensatte plater av den innledningsvis nevnte art. Dette . oppnås i henhold til oppfinnelsen ved at sjiktene i kjernen er forbundet med hverandre bare i det mindtre område hvorved de s-jikt-flater som vender mot hverandre har hver en overflate som muliggjor fri glidebevegelse av kantpartiene. The purpose of the present invention is to overcome this disadvantage of composite plates of the type mentioned at the outset. This . is achieved according to the invention in that the layers in the core are connected to each other only in the smaller area whereby the layer surfaces that face each other each have a surface that enables free sliding movement of the edge parts.
For kjernesjiktene benyttes et egnet varmeisolerende material som f.eks. skumfiber eller mineralfiber. Kjernesjiktene kan' i det midtre område være forbundet med hverandre, når det dreier seg om f.eks. prefabrikerte isolasjonsplater med glatt overflate, som fritt kan gli mot hverandre i kantområdene. A suitable heat-insulating material is used for the core layers, such as e.g. foam fiber or mineral fiber. The core layers can be connected to each other in the middle area, when it concerns e.g. prefabricated insulation boards with a smooth surface, which can freely slide against each other in the edge areas.
På den annen side er det også mulig å klebe eller sveise kjernesjiktene til hverandre under mellomlegg av en gjennomgående skillefolie.. Denne skillefolie kan i sitt midtre område også være utformet méd minst en åpning gjennom hvilken de to Icjernesjikt forbindes med hverandre. On the other hand, it is also possible to glue or weld the core layers to each other under the interposition of a continuous separating foil. This separating foil can also be designed in its middle area with at least one opening through which the two iron layers are connected to each other.
Fremgangsmåten i henhold til- oppfinnelsen .for fremstilling av en slik sammensatt plate.består i at det på -en metallplate anbringes et forste rystesjikt av lost skummede kunststoffkorn som er omsluttet av et" bindemiddel, a-t det på det forste rystesjikt anbringes en .skillef olie som har minst en ikke klebbar overflate og som i sitt midtområde.har minst en åpning at.det på skillefolien anbringes et ytterligere rystesjikt av,lost skummede kunststoffkorn som er omsluttet' av. et bindemiddel og at en metallplate anbringes på det ytterligere rystesjikt, hvoretter det hele sammenpresses til en,sammensatt plate, idet de to sjikt forbindes med hverandre gjennom åpningen eller åpningene i skillefoliene. ' The method according to the invention for the production of such a composite plate consists in placing on a metal plate a first shaking layer of loosely foamed plastic grains which are surrounded by a binder, and on the first shaking layer a separation oil is placed which has at least one non-adhesive surface and which in its central area has at least one opening so that a further shaking layer of loosely foamed plastic grains which are surrounded by a binder is placed on the separating film and that a metal plate is placed on the further shaking layer, after which the whole is compressed into a composite plate, the two layers being connected to each other through the opening or openings in the separating foils.
Ved en sådan sammensatt plate kan således sjiktenes randpartier utvide seg eller trekke seg sammen uavhengig av hverandre, således at det på denne enkle måte oppnås en vesentlig redusering av nevnte deformering av sammensatte plater ved vesentlig forskjellig varmeinnvirkning på de to platesider. Herunder blir den gode varmeisolasjon og egenstivheten, dvs. boyemotstanden, for en sådan sammensatt plate bare i ubetydelig grad eller ikke i det hele tatt nedsatt. With such a composite plate, the edge portions of the layers can thus expand or contract independently of each other, so that in this simple way a substantial reduction of said deformation of composite plates is achieved by significantly different heat effects on the two plate sides. Below this, the good thermal insulation and the intrinsic stiffness, i.e. the buoyancy resistance, of such a composite plate are reduced only to a negligible extent or not at all.
På den vedfoyde tegning er det vist et utforelseseksempel for en sammensatt plate i henhold til oppfinnelsen, og som er vist i perspektiv. The attached drawing shows an embodiment of a composite plate according to the invention, which is shown in perspective.
Nevnte sammensatte -plate omfatter et ytre metall-lag 1 som fortrinnsvis er av aluminium og ca. 2 mm tykt. Et annet identisk ytterlag 2 befinner seg på den annen ytterside av -den sammensatte plate. Said composite plate comprises an outer metal layer 1 which is preferably made of aluminum and approx. 2 mm thick. Another identical outer layer 2 is located on the other outer side of the composite plate.
Mellom ytterlagene er det anordnet en kjerne som er -oppdelt i to sjikt 3, 1+ av syntetisk isolasjonsmaterial, idet det mellom sjiktene er lagt inn en skille-folie 5- --Denne skillefolie 5»Between the outer layers, a core is arranged which is -divided into two layers 3, 1+ of synthetic insulation material, with a separating foil 5 inserted between the layers- --This separating foil 5"
som ikke behover å klebes fast til kjernesjiktene, og f.eks. kan bestå av hensiktsmessig behandlet papir, kunststoff eller aluminium, er i sitt midtområde forsynt med en åpning eller en utskjæring 6. I stedet for en eneste stor åpning kan det også which do not need to be glued to the core layers, and e.g. can consist of suitably treated paper, plastic or aluminium, is provided in its central area with an opening or a cut-out 6. Instead of a single large opening, it can also
i nevnte område anordnes "flere mindre åpninger.. De to sjikt 3, h er forbundet med hverandre gjennom denne åpning 6, mens in said area, "several smaller openings" are arranged. The two layers 3, h are connected to each other through this opening 6, while
sjiktenes ytre randsoner bare ligger lost an mot skille-follen 5, hvorved det oppnås at disse randsoner kan utvide seg uavhengig av hverandre. Hverved kan en krumning av den sammensatte plate på grunn av et temperaturfall"over platen, holdes innenfor trange grenser. Det viser seg at utbuktningen på grunn av ensidig oppvarmning av en sådan plate i henhold til oppfinnelsen bare utgjor en brokdel av den utbuktning som kan påvises ved konvensjonelle sammensatte plater. Omfanget av det sammenføyde midtområde kan varieres'innenfor visse grenser og avhenger vesentlig av anvendelsesområdet for vedkommende'plater, platestorrelsen, den ventede temperaturforskjell og den tillatte utbuktning samt den påkrevede sammenfSyningsfasthet mellom de to sjikt 3, h. Hvis kantene av den sammensatte plate skal innfåttes i en ramme, må det sorges for at de to sjikt 3? ^ kan utvide seg eller trekke seg sammen uavhengig av hverandre i vedkommende innfatning. the outer edge zones of the layers only lie loosely against the separating fold 5, whereby it is achieved that these edge zones can expand independently of each other. In this way, a curvature of the composite plate due to a temperature drop across the plate can be kept within narrow limits. It turns out that the bulge due to one-sided heating of such a plate according to the invention only constitutes a fraction of the bulge that can be detected in the case of conventional composite panels. The extent of the joined central area can be varied within certain limits and depends significantly on the area of application for the panels in question, the panel size, the expected temperature difference and the permissible bulge as well as the required joint strength between the two layers 3, h. If the edges of the composite plate is to be framed in a frame, it must be ensured that the two layers 3?^ can expand or contract independently of each other in the frame in question.
Som material for sjiktene 3> egner seg et syntetisk harpiks-skum med sluttet cellestruktur, f.eks. på basis av skum-polystyrol. Det dreier seg her om skumstoff-korn, fortrinnsvis av blæret polystyrol, som sammen med et bindemiddel og faststoff-pulver sammenpresses, slik at det oppnås et legeme A synthetic resin foam with a closed cell structure is suitable as material for the layers 3>, e.g. based on polystyrene foam. This involves foam grains, preferably of expanded polystyrene, which together with a binder and solid powder are pressed together, so that a body is obtained
med liten egenvekt og hoy holdfasthet og formstabilitet. with low specific weight and high holding strength and shape stability.
I stedet for en folie med en eller flere åpninger i sitt midtområde kan det også anvendes en gjennomløpende folie uten åpninger. I dette tilfelle blir de to sjikt 3, k i midtområdet klebet eller sveiset til folien på hver sin side, mens det i'de' ovrige områder ikke foretas noen sammenklebning eller sammeri-sveisning. Instead of a foil with one or more openings in its central area, a continuous foil without openings can also be used. In this case, the two layers 3, k in the central area are glued or welded to the foil on each side, while in the other areas no gluing or joint welding is carried out.
De to sjikt 3, k gjores fortrinnsvis omtrent like tykke. Sjiktenes tykkelse av-passes etter den bnskede varmeisolasjon og er i praksis av størrelsesorden 1 til k- cm. Overf late struktur én og farvningen av metallplatene 1, 2 kan uten vesentlig begrensning tilpasses de foreliggende behov. The two layers 3, k are preferably made approximately the same thickness. The thickness of the layers is adjusted according to the desired heat insulation and is in practice of the order of 1 to k-cm. The surface structure 1 and the coloring of the metal plates 1, 2 can be adapted to the present needs without significant limitation.
I dét folgende vil en foretrukket fremgangsmåte for fremstilling In the following, a preferred method of production will be given
av en sådan sammensatt plate bli beskrevet: of such a composite plate be described:
På en metallplate som er omgitt av en kant eller en form, og som f.eks. utgjores av en stor, flat aluminiumsplate 1, blir det fordelt lose skumstoff-korn. Disse avrundete skumstoff-korn er innsatt med et bindemiddel, f.eks. en harpiks med påfort bindemiddel, og utenpå dette påfort et finkornet pulver, f.eks. et- mineralpulver.' Etter at dette påforte sjikt er utjevnet blir en skille-folie med et sentralt utsnitt anbragt ovenpå skumstoff-' korn-sjiktet. For å hindre fastklebning av de bindemiddel-belagte skumstoff-korn til folien, kan denne på begge sider være behandlet med et skillemiddel, f.eks. på silikon-basis. Deretter anbringes et annet sjikt av skumstoff-korn på nevnte folie, og ovenpå dette, en ytterligere like stor aluminiumsplate 2. Til slutt blir det hele sammpresset, hvorunder herdningen av bindemidlet kan påskyndes ved hjelp av varme. Volumet av korn-massen reduseres under sammen-presningen til f.eks. det halve av den opprinnelige verdi. På de steder som ikke er dekket av folie, altså i midtområdet, vil de to sjikt 3, % forbinde seg med hverandre, slik at de i dette området vil utgjore et eneste legeme. On a metal plate which is surrounded by an edge or a shape, and which e.g. is made of a large, flat aluminum plate 1, loose foam grains are distributed. These rounded foam grains are inserted with a binder, e.g. a resin with an applied binder, and on top of this a fine-grained powder is applied, e.g. et- mineral powder.' After this applied layer has been smoothed out, a separating foil with a central cutout is placed on top of the foam grain layer. In order to prevent the binder-coated foam grains from sticking to the foil, this can be treated on both sides with a separating agent, e.g. on a silicone basis. Next, another layer of foam material grains is placed on said foil, and on top of this, a further aluminum plate 2 of the same size. Finally, the whole is compressed, during which the hardening of the binder can be accelerated with the help of heat. The volume of the grain mass is reduced during compression to e.g. half of the original value. In the places that are not covered by foil, i.e. in the middle area, the two layers 3.% will connect with each other, so that in this area they will form a single body.
En sådan sammensatt plate egner seg spesielt for anvendelse som dorplate, da den selv ved meget forskjellige ytter- og inner-, temperaturer forblir meget formstabil. Such a composite plate is particularly suitable for use as a mandrel plate, as it remains very dimensionally stable even at very different external and internal temperatures.
