Description
Fremgangsmåte for fremstilling av paneler eller veggkonstruksjoner. Procedure for the manufacture of panels or wall structures.
Denne oppfinnelse vedrører en fremgangsmåte for fremstilling av paneler eller veggkonstruksjoner med stor mekanisk styrke og gode varmeisolerende egenskaper, samt paneler og veggkonstruksjoner som er fremstilt ved fremgangsmåten. This invention relates to a method for producing panels or wall constructions with great mechanical strength and good heat insulating properties, as well as panels and wall constructions produced by the method.
Oppfinnelsen er særlig hensiktsmessig for fremstilling av yeggpaneler for kalde lagringskammere, varmeisolerte transportbehol-dere av små og store dimensjoner, kjølekabinetter og isolerende vegg-paneler. The invention is particularly suitable for the production of egg panels for cold storage chambers, heat-insulated transport containers of small and large dimensions, cooling cabinets and insulating wall panels.
Ved fremstilling av støpestykker av syntetisk harpiks som er forsterket med fibermateriale har man vanskeligheter i forbindelse med fullstendig impregnering av fibermaterialet ved hjelp av harpiks. Dette skyldes harpiksens viskositet og de små passasjer eller mellomrom mellom fibrene, gjennom hvilke harpiksen skal renne. Harpiksen søker å bevege fibrene foran seg og sammenpakker dermed fibrene mot formens ene ende. In the production of castings of synthetic resin which are reinforced with fiber material, there are difficulties in connection with complete impregnation of the fiber material by means of resin. This is due to the viscosity of the resin and the small passages or spaces between the fibers through which the resin must flow. The resin seeks to move the fibers in front of it and thus packs the fibers together towards one end of the mold.
Fremgangsmåten ifølge oppfinnelsen går ut på at der i en form anbringes et kjernelag av varmeisolerende materiale mellom to lag av forsterkende fibermateriale og at syntetisk harpiks i form av væske innføres i formen for impregnering av det forsterkende fibermateriale, og fremgangsmåten ifølge oppfinnelsen utmerker seg ved at kjernelagets overflater forsynes med spor eller kanaler langs hvilke den væskeformede, syntetiske harpiks renner for i det vesentlige fullstendig impregnering av alt forsterkende materiale i formen. The method according to the invention consists in placing a core layer of heat-insulating material in a mold between two layers of reinforcing fiber material and that synthetic resin in the form of liquid is introduced into the mold for impregnation of the reinforcing fiber material, and the method according to the invention is distinguished by the core layer's surfaces are provided with grooves or channels along which the liquid synthetic resin flows for essentially complete impregnation of all reinforcing material in the mold.
Ved at man i samsvar med oppfinnelsen anordner kanaler eller spor i kjernelagets overflate, dannes det passasjer gjennom hvilke harpiksvæsken kan renne relativt fritt for å kunne fordeles over i det vesentlige hele overflatearealet av støpestykket, og det fibrøse materiale vil impregneres med harpiksen som renner ut av sporene eller kanalene i det vesentlige i retning på tvers av fiber-materiallagets tykkelse, slik at man oppnår i det vesentlige jevn impregnering med ubetydelig forskyvning av fibermaterialet. By arranging channels or grooves in the surface of the core layer in accordance with the invention, passages are formed through which the resin liquid can flow relatively freely in order to be distributed over essentially the entire surface area of the casting, and the fibrous material will be impregnated with the resin that flows out of the grooves or channels essentially in the direction across the thickness of the fiber material layer, so that essentially uniform impregnation is achieved with negligible displacement of the fiber material.
Kjernelaget består fortrinnsvis av et sjikt eller lag av ekspandert, syntetisk plastmateriale, såsom ekspandert polystyren, ekspandert polyvinylklorid eller ekspandert polyurethan. Dette materiale er i det vesentlige stivt og har fortrinnsvis en struktur med lukkede celler. Det forsterkende fibermateriale består fortrinnsvis av glassfibre, hensiktsmessig i form av glassfibermatter. The core layer preferably consists of a layer or layers of expanded, synthetic plastic material, such as expanded polystyrene, expanded polyvinyl chloride or expanded polyurethane. This material is essentially rigid and preferably has a closed-cell structure. The reinforcing fiber material preferably consists of glass fibers, suitably in the form of glass fiber mats.
Oppfinnelsen omfatter også panel- eller veggkonstruksjoner som er fremstilt ved fremgangsmåten. The invention also covers panel or wall constructions produced by the method.
Oppfinnelsen skal forklarés nærmere ved hjelp av eksem-pler under henvisning til tegningen, hvor: Fig. 1 er et perspektivriss tildels i snitt av en kon-struksjon bestående av et kjernelag og fiberforsterkede lag før an-bringelse i formen, fig. 2 viser et snitt gjennom en form for fremstilling av plane paneler, og fig. 3 viser et snitt gjennom en form til fremstilling av bokslignende veggkonstruksjoner for varmeisolerende beholdere eller for kjølekabinetter. The invention shall be explained in more detail by means of examples with reference to the drawing, where: Fig. 1 is a perspective view partly in section of a construction consisting of a core layer and fibre-reinforced layers before placement in the mould, fig. 2 shows a section through a form of production of flat panels, and fig. 3 shows a section through a mold for producing box-like wall constructions for heat-insulating containers or for cooling cabinets.
Som vist på fig. 1 består fyllingen som skal anbringes i formen, av et kjernelag 1 av ekspandert, syntetisk plastmateriale med rekker med parallelle spor 2 i hver av materialets motsatte overflater eller sider. Over hver ytterflate finnes et lag 3 bestående av glassfibermatte. As shown in fig. 1, the filling to be placed in the mold consists of a core layer 1 of expanded, synthetic plastic material with rows of parallel grooves 2 in each of the opposite surfaces or sides of the material. Above each outer surface there is a layer 3 consisting of fiberglass mat.
Ved utførelsen ifølge fig. 2 består formen for fremstilling av flate paneler av to plane, stive plater 4 som er anordnet mot ytterflatene av to forsterkende fiberlag 3 og omsluttet av en bøyelig pose 5 som hensiktsmessig er fremstilt av folie av polyvi-nylalkohol, og som har et innløp 6 for harpiks utformet ved sin ene ende og et utløp 7 for luft ved den annen ende. Platene 4 kan være av metall eller av hårdplast. In the embodiment according to fig. 2, the form for the production of flat panels consists of two flat, rigid plates 4 which are arranged against the outer surfaces of two reinforcing fiber layers 3 and enclosed by a flexible bag 5 which is conveniently made from foil of polyvinyl alcohol, and which has an inlet 6 for resin formed at one end and an outlet 7 for air at the other end. The plates 4 can be made of metal or hard plastic.
En mengde væskeformig, kaldherdende polyesterharpiks som er tilstrekkelig til å forme den nødvendige panel, sprøytes inn i formen gjennom innløpet 6 ut fra en beholder (ikke vist) idet tryk-ket er omtrent 0,7 kg/cm 2. Formen evakueres gjennom luftutløpsåp-ningen 7 til et trykk på omtrent 13 cm Hg absolutt trykk, og harpiksvæsken trekkes eller suges gjennom formen idet den først strømmer eller renner langs sporene 2 i kjernelaget. og deretter passerer fra sporene 2 inn i lagene 3 av fiberforsterkningsmaterialet. Harpiksvæsken fordeles således til lagene 3 over i det vesentlige hele overflatearealet av formen, slik at man oppnår i det vesentlige jevn impregnering av fibrene med ubetydelig forskyvning av fibermaterialet. Prosessen kan utføres med former som står vertikalt, lig-ger horisontalt eller er anordnet på skrå og hvor harpiksinnløpet kan være over eller under luftutløpet. An amount of liquid, cold-hardening polyester resin which is sufficient to form the required panel is injected into the mold through the inlet 6 from a container (not shown), the pressure being approximately 0.7 kg/cm 2 . The mold is evacuated through the air outlet opening ning 7 to a pressure of approximately 13 cm Hg absolute pressure, and the resin liquid is drawn or sucked through the mold as it first flows or flows along the grooves 2 in the core layer. and then passes from the grooves 2 into the layers 3 of the fiber reinforcement material. The resin liquid is thus distributed to the layers 3 over essentially the entire surface area of the mold, so that essentially even impregnation of the fibers is achieved with negligible displacement of the fiber material. The process can be carried out with molds that stand vertically, lie horizontally or are arranged at an angle and where the resin inlet can be above or below the air outlet.
Platene 4 sikrer den støpte panelkonstruksjon glatte overflater.. Panelet kan tas ut av formen når harpiksen er tilstrekkelig modnet eller herdnet. The plates 4 ensure the molded panel construction smooth surfaces. The panel can be removed from the mold when the resin has sufficiently matured or hardened.
Ved en modifisert utførelse kan flere fyllinger med kjer-ner 1 og forsterkningslag 3 anbringes i en form med ytterligere stive formplater 4 mellom fyllingene slik at flere paneler kan støpes samtidig. In a modified version, several fillings with cores 1 and reinforcement layers 3 can be placed in a mold with further rigid form plates 4 between the fillings so that several panels can be cast simultaneously.
Fig. 3 viser en form for fremstilling av bokslignende eller kasselignende veggkonstruksjoner som egner seg til bruk i varmeisolerte beholdere eller kjølekabinetter. Formen har en stiv formdel 20 som brukes til støpning av den indre flate av konstruk-sjonen, og en bøyelig formdel 21 som på sine kanter er festet til kantene av den stive formdel 20 ved hjelp av klemmer 12. Fig. 3 shows a form of production of box-like or box-like wall constructions which are suitable for use in heat-insulated containers or cooling cabinets. The mold has a rigid mold part 20 which is used for molding the inner surface of the construction, and a flexible mold part 21 which is attached at its edges to the edges of the rigid mold part 20 by means of clamps 12.
Lag 3 av forsterkningsmateriale som kan bestå av glassfibermatter, og et kjernelag 1 som kan bestå av på forhånd form-støpt kjernemateriale eller som kan være sammensatt av sjikt av kjernemateriale, er anordnet i formen som vist. Den stive formdel har to eller flere innløp 6 for harpiks i nærheten av sin nedre del. Et utløp 7 for luft er utformet i toppen av den bøyelige, fleksible formdel 21. Layer 3 of reinforcement material which may consist of glass fiber mats, and a core layer 1 which may consist of pre-molded core material or which may be composed of layers of core material, are arranged in the mold as shown. The rigid mold part has two or more inlets 6 for resin near its lower part. An outlet 7 for air is formed at the top of the bendable, flexible mold part 21.
Væskeformig harpiks sprøytes inn i formen gjennom innlø-pet 6 og formen evakueres og støpestykket fremstilles på en lignen-de måte som forklart i forbindelse med fig. 2. Liquid resin is injected into the mold through the inlet 6 and the mold is evacuated and the casting is produced in a similar way as explained in connection with fig. 2.
Harpiksen som brukes er vanligvis av den type som nor-malt anvendes i industrien som benytter armerte plaster, f.eks. en polyester eller epoxyharpiks, og harpiksens viskositet skal være tilstrekkelig lav for å tillate kort impregneringstid. Vanligvis benyttes en kaldherdende harpiks, selv om også varmherdende harpiks kan brukes. The resin used is usually of the type normally used in the industry that uses reinforced plasters, e.g. a polyester or epoxy resin, and the viscosity of the resin must be sufficiently low to allow a short impregnation time. Usually a cold-setting resin is used, although hot-setting resin can also be used.
Ved hjelp av oppfinnelsen kan man raskt og lett fremstil-le varmeisolerende paneler eller veggkonstruksjoner med tette og i det vesentlige porefrie overflatelag av fiberforsterket, syntetisk harpiks. På grunn av det lave differansetrykk som er alt som kre-ves for å oppnå at harpiksvæsken renner gjennom formen, er det ikke nødvendig å benytte tunge og altfor sterke støpeformer. With the help of the invention, heat-insulating panels or wall constructions with dense and essentially pore-free surface layers of fibre-reinforced synthetic resin can be quickly and easily produced. Due to the low differential pressure, which is all that is required to achieve that the resin liquid flows through the mold, it is not necessary to use heavy and excessively strong moulds.
