i DK 167858 B1in DK 167858 B1
Opfindelsen omhandler et ekstruderet, sammensat materiale især beregnet til forstærknings formål og bestående af en kontinuert termoplastisk kappe og en kerne.The invention relates to an extruded composite material especially intended for reinforcement purposes and consisting of a continuous thermoplastic sheath and a core.
5 Sammensatte materialer af denne art er kendt, især med kerner af metal, såsom kabler eller elektriske ledninger.Composite materials of this kind are known, especially with metal cores, such as cables or electrical wires.
Fremstillingen af sådanne materialer, eksempelvis som beskrevet i USA-patent nr. 3 764 642, muliggør dog kun en 10 fremstilling af sammensatte materialer med en kerne, der er lidet følsom over for ikke blot kappematerialets smeltepunkt, men også over for ekstruderens temperatur.However, the production of such materials, for example, as described in U.S. Patent No. 3,764,642, allows only a preparation of composite materials having a core which is not sensitive to not only the melting point of the sheath material, but also to the extruder temperature.
Dette gælder også for fransk patentskrift nr. 2 021 601, der beskriver et apparat til pålægning af en kappe om-15 kring et termoplastisk materiale med en stor længde og med et højere smeltepunkt end kappens og altså lidet følsom over for kappens ekstruderingstemperatur. Sædvanligvis fremstilles disse sammensatte materialer ved eks-trudering ved at lade en metaltråd passere igennem kappe-20 pålægningsdysen. Ved en sådan teknik er det altså utænkeligt at kunne fremstille et sammensat materiale med en kerne, der ikke kan tåle kappens ekstruderingstemperatur.This also applies to French Patent Specification No. 2 021 601, which describes an apparatus for applying a sheath around a thermoplastic material of a great length and having a higher melting point than the sheath's and thus not very sensitive to the extrusion temperature of the sheath. Usually these composite materials are made by extrusion by passing a metal wire through the sheath nozzle. Thus, in such a technique, it is inconceivable to be able to produce a composite material with a core that cannot withstand the extrusion temperature of the jacket.
Ifølge beskrivelsen til europæisk patent nr. 0133825 er 25 det kun muligt af fremstille et sammensat materiale, hvor kernens smeltepunkt er mindst lige så stort som kappens, dvs. et materiale med en kerne, der er ufølsom over for kappepålægningstemperaturen ved de kendte arbejdsbetingelser.According to the specification of European Patent No. 0133825, it is only possible to produce a composite material where the melting point of the core is at least as great as that of the jacket, i.e. a material with a core which is insensitive to the coating application temperature under the known working conditions.

Opfindelsen har til formål at afhjælpe denne ulempe og at kunne fremstille et sammensat materiale, hvis kerne, ifølge den givne definition, er følsom over for pålægningstemperaturforholdene .The invention has for its object to alleviate this disadvantage and to be able to produce a composite material whose core, according to the given definition, is sensitive to the application temperature conditions.
Dette opnås ifølge med et materiale som angivet i kravets kendetegnende del.This is achieved according to a material as defined in the characterizing part of the claim.

Som kappemateriale kan vælges et vilkårligt formstof, som er termoplastisk efter dets ekstrudering. Kernen kan være et pulver, men også fibre eller en tekstur, der er følsom 5 over for kappens temperatur, eller vilkårlige fibre imprægneret med et pulver, der er følsomt over for kappens smeltetemperatur. Almindeligvis består kernen af et pulver og/eller fibre, hvis fysiske udseende eller tekstur let kan beskadiges ved kappens ekstruderingstemperatur.As a sheath material, any resin may be selected which is thermoplastic after its extrusion. The core may be a powder but also fibers or a texture sensitive to the sheath temperature, or any fibers impregnated with a powder sensitive to the sheath melt temperature. Generally, the core consists of a powder and / or fibers whose physical appearance or texture can be easily damaged by the jacket extrusion temperature.
1010
Kernens fibre er eksempelvis af tekstil, kul eller glas.The core fibers are, for example, textile, coal or glass.
Den forud for kappepålægningen stedfindende imprægnering af fibrene med pulver er kendt og kan ved en konventionel 15 fremgangsmåde ske ved at lade fibrene passere gennem et fluidiserende lag af pulveret som beskrevet i europæisk patentskrift nr. 0133825.The impregnation of the fibers with powder prior to the coating is known and can be done by a conventional method by passing the fibers through a fluidizing layer of the powder as described in European Patent No. 0133825.
Det sammensatte materiale ifølge opfindelsen fremstilles 20 på konventionel måde ved ekstrudering af kappen, men med det særlig arrangement ud for det særskilte ekstrude-ringshoved.The composite material according to the invention is prepared in a conventional manner by extrusion of the jacket, but with the particular arrangement next to the separate extrusion head.
Opfindelsen forklares nærmere nedenfor i forbindelse med 25 tegningen, der viser et aksialt snit igennem et apparat til fremstilling af det sammensatte materiale ifølge opfindelsen.The invention is further explained below in connection with the drawing, which shows an axial section through an apparatus for making the composite material according to the invention.
Apparatet omfatter en rørformet dyse 1 og en dorn 2, hvis 30 rækkefølge eventuelt kan ombyttes i forhold til den på figuren viste, og af et styrerør 3 for kernen. Styrerøret 3, der eventuelt kan holdes afkølet ved hjælp af en køleanordning 4, er anbragt således, at dets udløbsende udmunder i det væsentlige i flugt med og fortrinsvis i 35 det væsentlige i aksen for udløbskanten af den apparatdel, som former kappens indervæg, det vil sige i det væsentlige i flugt med dornen 2, under opretholdelse DK 167858 B1 3 af en kanal 5 til et kølemiddel, hvilken kanal kan strække sig lige til apparatets udløbskanal 6 for ekstrude-ringsmaterialet.The apparatus comprises a tubular nozzle 1 and a mandrel 2, the order of which may be exchanged in relation to that shown in the figure, and of a guide tube 3 for the core. The control tube 3, which may be kept cool by means of a cooling device 4, is arranged so that its outlet end opens substantially in flight with and preferably substantially in the axis of the outlet edge of the device part which forms the inner wall of the jacket, say, substantially in flight with the mandrel 2, while maintaining a channel 5 for a refrigerant, which channel may extend straight to the outlet channel 6 of the extruder material.
5 Ifølge opfindelsen er styrerøret 3 ved sin udløbsende afsluttet med et mundstykke med sidevendende huller, og desuden har dette mundstykkes udløbskanal, der fortrinsvis er koaksial med styrerøret, en diameter, der både overstiger diameteren for den gennem styrerøret udstrøm-10 mende kerne og er mindre end inderdiameteren for resten af styrerøret. Dette mundstykke, der er antydet med sort på tegningen ved hovedet af styrerøret 3, har til opgave at styre kølemidlet, normalt en luftstrøm, der ankommer gennem kanalen 5. Dette kølemiddel, der helt eller delvis 15 skifter retning gennem mundstykkets sidevendende huller, vil med en mindre kraft ramme kernematerialet 14 og den i kanalen 6 dannede kappe. Dette arrangement er særlig hensigtsmæssigt, når kernen mere eller mindre udgøres af et pulver. Ved at forskyde styrerøret 3 således, at mund-20 stykkets ende kommer i berøring med dornen 2, er det muligt, som vist på figuren, helt at tillukke kanalen 5 før udløbet fra den del af apparatet, som danner kappens in-dervæg. Ved en sådan total lukning sendes kølemidlet, hvis retning er ændret af mundstykkets sidevendende hul-25 ler, tilbage mod styrerørets indre uden at komme i direkte berøring med kappen. Antallet af sidevendende huller er mindst to modsat beliggende huller, men for at sikre en god drift er det hensigtsmæssigt at udforme en krans af huller omkring mundstykket.According to the invention, the guide tube 3 is terminated at its outlet end with a nozzle with lateral holes, and furthermore, the outlet channel of this nozzle, which is preferably coaxial with the guide tube, has a diameter which both exceeds the diameter of the core flowing through the guide tube and is smaller. than the inner diameter of the rest of the guide tube. This nozzle, indicated in black in the drawing at the head of the guide tube 3, has the task of controlling the coolant, usually an air flow arriving through the duct 5. This coolant, which changes wholly or partially through the nozzle's lateral holes, will with a minor force strikes the core material 14 and the sheath formed in the channel 6. This arrangement is particularly convenient when the core is more or less constituted by a powder. By displacing the guide tube 3 so that the end of the nozzle comes into contact with the mandrel 2, it is possible, as shown in the figure, to completely close the duct 5 before the outlet of the part of the apparatus forming the inner wall of the sheath. At such a total closure, the refrigerant, the direction of which is changed by the sidewall holes of the nozzle, is sent back toward the interior of the guide tube without coming into direct contact with the sheath. The number of lateral holes is at least two opposite holes, but in order to ensure good operation, it is appropriate to form a garland of holes around the mouthpiece.
30 På konventionel måde er opbygningen af ekstruderingsdysen og dornen monteret som et vinkelformet hoved 7 fastgjort ved hjælp af en spændemøtrik 8. For at forbedre styrerørets varmeisolation kan man overtrække de varme vægge af 35 kanalen 5 med et isolationsmateriale 9, der virker som en ekstra varmeskærm.Conventionally, the structure of the extrusion die and mandrel is mounted as an angular head 7 secured by a clamping nut 8. To improve the thermal insulation of the guide tube, the hot walls of the duct 5 can be coated with an insulating material 9 which acts as an additional heat shield. .

For maksimalt at formindske udstrålingen fra ekstrude-ringsapparatet anbefales det lige ved apparatets udløb at anbringe et varmeskjold 10, og de bedste resultater opnås med et skjold, der udgår i højde med apparatets yderkant.In order to minimize the radiation from the extruder, it is recommended to place a heat shield 10 at the outlet of the device, and the best results are obtained with a shield extending at the outer edge of the device.
5 Skjoldets effektivitet kan forbedres eksempelvis ved at tilføre en luftstrøm igennem et rør 11, hvilken luftstrøm samtidigt kan virke til at opretholde et modtryk på det ekstruderede materiale ved hjælp af en luftgennemstrøm-ningsformindsker 12. Det beskrevne aggregat kan anvendes 10 i forbindelse med en konventionel ekstruder under udøvelse af konventionelle ekstruderings-fremgangsmåder.The efficiency of the shield may be improved, for example, by supplying an air flow through a pipe 11 which may simultaneously act to maintain a backpressure on the extruded material by means of an air flow reducer 12. The assembly described may be used in connection with a conventional extruder in the practice of conventional extrusion methods.
Enden af styrerøret 3, det vil sige enden af mundstykket beliggende i det væsentlige i flugt med udløbskanten af 15 den apparatdel, som former kappens indervæg, kan befinde sig inden for kanten, men den kan også som vist på figuren udmunde uden for ekstruderingsdysens udløbskant. Fortrinsvis er afstanden mellem mundstykkets udløbsende fra dornkanten, henholdsvis afstanden mellem mundstykkets 20 udløbsende og ekstruderingsdysens udløbskant, af størrelsesordenen højst 4 mm.The end of the guide tube 3, that is, the end of the nozzle substantially aligned with the outlet edge of the apparatus portion forming the inner wall of the sheath, may be within the edge, but it may also open as shown in the figure outside the outlet edge of the extrusion die. Preferably, the distance between the outlet end of the nozzle from the mandrel edge, or the distance between the outlet end of the nozzle 20 and the outlet edge of the extrusion nozzle, is of the order of at most 4 mm.
Der ekstruderes en formstofkappe igennem en kanal 13 i ekstruderingsdysen, medens der samtidigt ved den modsatte 25 ende af styrerøret 3, eventuelt afkølet og virkende som en tragt, indføres det materiale 14, der udgør kernen, og som møder kappen ved apparatets udløb, idet der etableres en afkøling i det væsentlige ud for apparatets udløb mellem kappens indervæg og kernematerialet således, at ker-30 nen ikke kan angribes af temperaturen af apparatet eller af kappen ved udløbet 6. Dette kan ske ved at indsprøjte afkølet luft ved 15 i kanalen 5 mellem styrerøret 3 og apparatets varme væg. Som følge af styrerørets fremspring ved apparatets udløb eller af afkølingsgraden for kappens 35 indervæg, eller som følge af begge dele, kan man opretholde det samlede materiale på en temperatur, der er tilstrækkelig lav til under hele kappepålægningsoperationen DK 167858 B1 5 af bevare dets praktisk taget originale udseende uden nogen væsentlig deformation.A plastic casing is extruded through a channel 13 in the extrusion die, while at the opposite end of the guide tube 3, optionally cooled and acting as a hopper, the material 14 constituting the core is introduced which meets the casing at the outlet of the apparatus. For example, a cooling is substantially established at the outlet of the apparatus between the inner wall of the casing and the core material so that the core cannot be attacked by the temperature of the apparatus or by the casing at outlet 6. This can be done by injecting cooled air at 15 in channel 5 between the control tube 3 and the hot wall of the apparatus. Due to the projection of the guide tube at the outlet of the apparatus or the degree of cooling of the inner wall of the sheath 35, or as a result of both, the total material can be maintained at a temperature sufficiently low to maintain its practically all over the sheath application operation DK 167858 B1 5. original appearance without any significant deformation.
For at forbedre kalibreringen af det sammensatte materi-5 ale eller endog forøge dettes afkølingshastighed er det muligt at sende en modstrøm af luft mod yderkappen ved dennes udgang fra apparatet. Dette kan eksempelvis ske ved at indsprøjte luft gennem røret 11 for varmeskjoldet 10.In order to improve the calibration of the composite material or even increase its cooling rate, it is possible to send a countercurrent of air towards the outer casing at its exit from the apparatus. This can be done, for example, by injecting air through the pipe 11 of the heat shield 10.

Det sammensatte materiale har talrige anvendelser, især til forstærkning af emner enten eksempelvis ved omvikling og opvarmning af materialet på emnet til sammensvejsning af opbygningen.The composite material has numerous uses, especially for reinforcing workpieces, for example by wrapping and heating the workpiece material for welding the structure.
