Abstract

Method of coating a door panel or the like with synthetic resin, which panel is provided with a synthetic insulating filling inside a sheet-metal shell to be coated on the outside, the heat resistance of which filling lies below the temperature which is required for the melting or coating of the synthetic resin powder applied to the outside surfaces of the sheet-metal shell. To prevent excessive thermal loading of the insulating filling, the said method is distinguished by the fact that the melting or coating temperature is carried out so quickly and briefly after applying the coating synthetic resin powder by means of an energy radiation, in particular with the aid of one or more energy beams, that the melting or coating temperature is reached in the applied synthetic resin powder or the boundary zone of the sheet-metal shell to be coated without the insulating filling being heated beyond its heat resistance, an energy radiation source being moved over the outer surface provided with synthetic resin powder of the sheet-metal shell, which is in particular kept stationary.

Description

DK 173024 B1 iDK 173024 B1 i

Opfindelsen angår en fremgangsmåde af den i krav l's indledning angivne art.The invention relates to a method of the kind set out in the preamble of claim 1.

Isolerede dør- eller portfløje og især portfløjpaneler af den art, der anvendes til ved portåbningens top ind- og 5 udskydelige lamelporte eller foldeporte, fremstilles økonomisk som masseartikel enten enkeltvis maskinelt eller som fortløbende streng som ved sektionsportpaneler.Insulated door or door wings, and especially door wing panels of the kind used for the top and 5 extendable slat gates or folding gates of the door opening, are manufactured economically as a mass article either individually by machine or as continuous string as by sectional door panels.

Denne streng opdeles derefter i de enkelte panellængder.This string is then divided into individual panel lengths.

Herved kan metalpladerne leveres til en vis grad 10 forbehandlet, f.eks. grundet, hvorefter isoleringslaget tilføres, f.eks. ved, at der i hulrummet i metalpladeskallen, som er formet af metalpladerne, der danner portfløjens ydre vægflade, indsprøjtes polyurethanskum. Metalpladeskallen kan også kun 15 færdiggøres på den ene side, dernæst fyldes med isoleringsmasse og til slut lukkes med en dækkende metalplade. Der kendes i princippet også isolerende fyldninger af andre materialer end polyurethanskum, hvilke har samme ringe modstandsdygtighed mod varme som 20 en isolering af en opskummet polyurethanmasse.Hereby, the metal sheets can be delivered to a certain extent 10 pretreated, e.g. due to which the insulating layer is applied, e.g. for example, polyurethane foam is injected into the cavity of the metal plate shell formed by the metal plates forming the outer wall surface of the gate wing. The metal plate shell can also only be finished on one side, then filled with insulating material and finally closed with a covering metal plate. In principle, insulating fillings of materials other than polyurethane foam are also known which have the same low heat resistance as insulation of a foamed polyurethane mass.

Så snart der kræves en yderfladebelægning af dør- eller portfløje henholdsvis portfløjpaneler, hvilken belægning ikke kan tilvejebringes inden for en massefremstilling, f.eks. på grund af forskellig klimatisk påvirkning og 25 især forskellig farvning eller strukturering, vil der være behov for en tilsvarende individualiseret overfladeudformning. Dette er ikke noget problem ved almindelige stuedøre, som kan males efter ønske. Døre bestående af en stålpladeskal med isolerende fyldning er 30 imidlertid som regel beregnet til at anvendes på steder, hvor der kræves robuste, vejrbestandige ydre beskyttelseslag. Velegnet til sådanne formål er en formstofbelægning tilvejebragt ved påføring af et termoplastisk formstofpulver på den ydre metalplade, der DK 173024 B1 2 skal belægges, og ved efterfølgende påsmeltning af pulveret under varmeindvirkning, tværbinding, påsintring eller ligende ved anvendelse af en temperatur, ved hvilken det på fladen jævnt påstrøede eller på anden måde 5 påførte formstofpulver smelter og indgår en varig kontakt med metalpladeskallens ydre flade til tilvejebringelse af omtalte formstofbelægning.As soon as an outer surface coating of door or door wing or gate wing panels is required, which coating cannot be provided within a mass production, e.g. due to different climatic influences and especially different staining or texturing, a corresponding individualized surface design will be needed. This is no problem at ordinary living room doors which can be painted as desired. However, doors consisting of a steel plate shell with insulating filling are generally intended to be used in places where robust, weatherproof outer protective layers are required. Suitable for such purposes is a plastic coating provided by the application of a thermoplastic plastic powder to the outer metal plate to be coated, and upon subsequent melting of the powder under heat effect, crosslinking, sintering or the like using a temperature at which On the surface, evenly sprayed or otherwise applied plastic powder 5 melts and enters a lasting contact with the outer surface of the metal plate shell to provide said plastic coating.

En sådan formstofbelægning af metalpladeflader er principielt kendt (US-A-4 308 296, "Oberflåche+Jot", 10 1986, hæfte 4, side 58-66) .Such a plastic coating of metal sheet surfaces is known in principle (US-A-4,308,296, "Oberflåche + Jot", 1986, booklet 4, pages 58-66).

En varmeisolerende fyldning af den angivne art er som nævnt kun varmebestandig inden for visse grænser.As mentioned, a heat insulating filling of the specified kind is only heat resistant within certain limits.

Bestemte slags polyurethanskum kan f.eks. allerede tage skade, når de påvirkes af temperaturer på over 70 til 15 80°C, idet f.eks. strukturen for isoleringsmaterialets vedhængning ved metalpladeskallens inderside forringes.Certain types of polyurethane foam can e.g. already damage when affected by temperatures above 70 to 15 80 ° C, e.g. the structure of the insulation material adhering to the inside of the metal plate shell deteriorates.

Denne vedhængning bidrager som oftest til dørens mekaniske styrke. På den anden side kræves der til ovennævnte belægning af metalplade med et først påstrøet 20 og dernæst opvarmet formstofpulver en væsentlig højere temperatur på alt efter formstofpulverets art ca. 180°c.This pendant usually contributes to the mechanical strength of the door. On the other hand, for the aforementioned coating of metal plate with a first sprinkled 20 and then heated plastic powder, a substantially higher temperature, depending on the nature of the plastic powder, is required. 180 ° C.

Der kan være tale om et formstofpulver på polyurethanbasis, polyesterbasis eller lignende. De påstrøede fine pulverkorn smeltes, og der tilvejebringes 25 en intim vedhængning af det smeltede pulver på metalskaloverfladen, så at der i overført betydning kan tales om en sintringsproces. På denne måde opnår man den ønskede vejrbestandige og slagfaste formstofbelægning på portfløj skallen.This may be a polyurethane-based, polyester-based, or the like, powdered plastic. The sprinkled fine powder grains are melted and an intimate adherence of the molten powder to the metal shell surface is provided so that a sintering process can be spoken of. In this way, the desired weather-resistant and impact-resistant plastic coating is obtained on the gate wing shell.

30 Det fremgår heraf, at den senere belægning af en metalpladeskal af den angivne art, i hvilken der allerede findes en isolerende fyldning, med formstof volder vanskeligheder derved, at den til formstofbelægningen DK 173024 B1 3 nødvendige temperatur er langt højere end den temperatur, som den isolerende fyldning, især en formstofskum-fyldning, tåler uden at beskadiges eller ødelægges.30 It can be seen from this that the later coating of a metal plate shell of the specified kind, in which there is already an insulating filling, with plastic material causes difficulties in that the temperature required for the plastic coating DK 173024 B1 3 is far higher than the temperature which the insulating filling, in particular a plastic foam filling, can withstand without being damaged or destroyed.

Det er derfor opfindelsens formål at forsyne en port-5 eller dørfløj eller et portfløjpanel med en formstofbelægning efter selve fløjens færdiggørelse, uden at den i forhold til belægningstemperaturen lave maksimale varmebelastningstemperatur for isoleringsfyldningen overskrides.It is therefore the object of the invention to provide a door or door or door panel with a plastic coating after completion of the door itself, without exceeding the low maximum thermal load temperature for the insulation filling.

10 Dette formål opnås ved fremgangsmåden ifølge krav 1. Ved fremgangsmåden ifølge opfindelsen opvarmes det på ydersiden af dør- eller portfløjens metalpladeskal påførte formstofpulverlag så hurtigt og intensivt til ind i skalyderfladens grænsezone, at den nødvendige 15 smeltningstemperatur nås, uden at denne temperatur overføres til isoleringsfyldningen på skallens inderside. Metalpladeskallen virker som skærm, der på grund af den gode varmeledningsevne fordeler den udefra tilførte varme på nabofladearealer på metalpladeskallen ved den 20 fortrinsvis kontinuerligt vandrende opvarmingszone, fra hvilke pladearealer varmen bortstråles eller bortledes, så at der alt i alt fra metalpladeskallens inderside afgives en væsentligt reduceret varmegradient til isoleringsfyldningen.This object is achieved by the method according to claim 1. In the method according to the invention, the plastic powder layer applied to the exterior of the metal plate shell of the door or door is heated so rapidly and intensively into the boundary zone of the sliding surface that the necessary melting temperature is reached without transferring this temperature to the insulation filling. on the inside of the shell. The metal plate shell acts as a shield which, due to its good thermal conductivity, distributes the externally applied heat to neighboring surface areas of the metal plate shell at the preferably continuously migrating heating zone, from which the plate areas heat is radiated or dissipated so that everything is substantially reduced from the inside of the metal plate shell. heat gradient for the insulation filling.

25 Det påførte formstofpulverlag hænger alt efter påføringsbetingelserne mere eller mindre godt fast i metalpladeskallens ydre flade, så at der er risiko for, at pulveret rystes af, når skallen udsættes for rystelser, hvilket er til hinder for opnåelsen af en jævn 30 belægning af yderfladen og dermed en ensartet vejrbestandighed og farve. Risikoen for en ujævn pu1verbelægning afhjælpes eller i det mindste reduceres væsentligt ved det i krav 3 angivne, hvorved DK 173024 B1 4 metalpladeskallen med det påførte formstofpulver står stille eller i det mindste kun bevæges meget roligt, hvilket ikke vill være muligt ved en kontinuerlig, endeløs fremstilling.Depending on the application conditions, the applied powder coating layer adheres more or less firmly to the outer surface of the metal plate shell, so that the powder may be shaken off when the shell is subjected to shaking, which prevents an even coating of the outer surface and hence a uniform weather resistance and color. The risk of uneven powder coating is mitigated or at least substantially reduced by the method of claim 3, whereby the metal plate shell with the applied plastic powder stands still or at least moves very slowly, which is not possible with a continuous, endless manufacture.

5 Energistrålingskildens bevægelse hen over metalpladeskallens stillestående ydre flade medfører, at en øgning af energistrålingskildens bevægelseshastighed kun har betydning for kildens holdeanordning, men ikke har nogen indvirkning på en produktionslinie med kontinuerlige 10 bevægelsesforløb for dør- eller portfløje.5 The movement of the energy radiation source across the stationary outer surface of the metal plate shell means that an increase in the velocity of movement of the energy radiation source only affects the source holding device, but has no effect on a production line with continuous movements of door or door.

Varmeafskærmningsvirkningen af skallens metalplademateriale er afhængig af opvarmingszonens lokalisering. Varmebortledningsevnen er f.eks. større, når opvarmnings-zonen er lokaliseret i midterområdet af metalplade-15 skallens yderside, end når opvarmingszonen er lokaliseret i skallens randområder. Der kan på forskellig vis tages hensyn til denne afhængighed af den fremførte opvarmningszones lokalisering, dels ved tilvejebringelse af et til varmebortledningen svarende bevægelsesforløb 20 for energistrålingskilden hen over metalpladeskallens yderflade, der skal belægges, i afhængighed af hastigheden og/eller afstanden, og dels ved regulering af energiudstrålingens intensitet, dvs. varmetilførslen i tidsenheden i tilpasning til de pågældende 25 varmebortledningsbetingelser. Disse foranstaltninger kan foretages særskilt eller i kombination med hinanden til optimering af stabilisationen af en beskyttelses- eller grænselagstemperatur, der kræves af hensyn til formstofbelægningen, men som ikke beskadiger 30 isoleringsmaterialefyldningen.The heat shielding effect of the metal sheet material of the shell is dependent on the location of the heating zone. The heat dissipation capability is e.g. larger when the heating zone is located in the middle region of the outer surface of the metal plate shell than when the heating zone is located in the peripheral regions of the shell. This dependence on the location of the heating zone carried out can be variously taken into account, in part by providing a heat transfer 20 corresponding to the heat radiation source across the outer surface of the metal plate shell to be coated, depending on the speed and / or distance, and partly on regulation. of the intensity of the energy radiation, ie. the heat supply in the time unit in accordance with the respective 25 heat dissipation conditions. These measures can be taken separately or in combination with each other to optimize the stabilization of a protective or boundary layer temperature required for the coating of plastics, but which does not damage the insulation material filling.

Principielt kan der til tilførsel af varme anvendes en hvilken som helst egnet energistråling. Man vil foretrække sådanne energistrålingsbærere, hvis virksomhed DK 173024 B1 5 og/eller virkning på omgivelser ikke kræver nogen særlige beskyttelsesforanstaltninger. Ifølge opfindelsen kan der fortrinsvis anvendes infrarød-, ultraviolet- eller laserstråler, som i passende bundtning definerer 5 opvarmningszonen. Temperaturen kan også reguleres på den angivne måde ved ændring af bundtningens eller fokuseringens intensitet.In principle, any suitable energy radiation can be used to supply heat. Such energy radiation carriers would be preferred if the company DK 173024 B1 5 and / or its effect on the environment does not require any special protective measures. Preferably, according to the invention, infrared, ultraviolet or laser beams can be used which, in appropriate bundling, define the heating zone. The temperature can also be adjusted in the manner indicated by changing the intensity of the bundling or focusing.

Der kan principielt arbejdes med et strålebundt, som på passende vis føres hen over metalpladeskallens med pulver 10 belagte ydre flade, der skal forsynes med et dæklag. Der findes fortrinsvis en eller flere rækker sådanne energistrålebundter, som stryges hen over nævnte ydre flade. Sådanne rækker af energistrålebundter kan til optimering af belægningstemperaturens stabilitet også 15 være indrettet til at bevæges modsat hinanden.In principle, a beam of beam can be worked which is appropriately passed over the outer surface of the metal sheet shell coated with powder 10 to be provided with a covering layer. Preferably, there are one or more rows of such energy beam bundles which are ironed over said outer surface. Such rows of energy beam bundles may also be adapted to move opposite each other to optimize the stability of the coating temperature.

Alt efter de betingelser, under hvilke formstofpulveret forberedende er påført på metalpladeskallens ydre flade, opnås en elektrostatisk betinget vedhængningseffekt mellem pulveret og denne flade, hvorved der sikres en 20 jævn fordeling af formstofpulveret. En sådan svag vedhængningseffekt inden energistrålingen mellem formstofpulveret og pladen, der skal belægges, kan forstærkes ved målrettet elektrostatisk opladning af omtalte flade og/eller af formstofpulveret. Sådanne 25 foranstaltninger er i princippet kendt.Depending on the conditions under which the plastic powder is applied preparatively to the outer surface of the metal plate shell, an electrostatic conditional bonding effect is obtained between the powder and this surface, thereby ensuring an even distribution of the plastic powder. Such a weak adhesion effect before the energy radiation between the plastic powder and the plate to be coated can be amplified by targeted electrostatic charging of said surface and / or of the plastic powder. Such 25 measures are known in principle.
