Description

148121148121

Den foreliggende opfindelse angår en isoleringsplade af mineraluld, fortrinsvis stenuld, der er sammenbundet ved hjælp af et termohærdende bindemiddel, hvilken plade har et øvre lag bestående af uvævede mineralf.ibre.The present invention relates to an insulating sheet of mineral wool, preferably stone wool, which is bonded together by a thermosetting binder, which plate has an upper layer consisting of nonwoven mineral fibers.

Isoleringsplader af denne type har den ulempe, at når de fastgøres til en overflade, der skal isoleres, og som i forvejen er blevet forsynet med en bituminøs belægning, opsuges der store mængder af bitumen. Dette frembyder den ulempe, at dels forøges omkostningerne til isoleringen, dels forbruges der store mængder materiale, som påvirker isoleringsevnen af isoleringspladen, fordi bitumen opsuges i de hulrum i pladen, som tjener til isoleringen.Insulating plates of this type have the disadvantage that when they are attached to a surface to be insulated and which have already been provided with a bituminous coating, large amounts of bitumen are absorbed. This presents the disadvantage that partly the cost of the insulation is increased and partly that large amounts of material are used which affect the insulating ability of the insulating plate, because bitumen is absorbed in the cavities in the plate which serve for the insulation.

Fra tysk offentliggørelsesskrift nr. 1.960.396 kendes således en isoleringsplade af glasfibre med et overfladelag, som indeholder uvævede glasfibre, og som er sammenbundet med de øvrige glasfibre ved hjælp af en formaldehydharpiks. En sådan plade er anvendelig til imprægnering med bitumen i overfladelaget, som opsuger store mængder bitumen.Thus, from German Publication No. 1,960,396, an insulating plate of glass fibers with a surface layer containing nonwoven glass fibers is known and which is bonded to the other glass fibers by means of a formaldehyde resin. Such a plate is useful for impregnating with bitumen in the surface layer, which absorbs large amounts of bitumen.

Man har forsøgt at eliminere problemerne med kraftig bitumenopsugning ved at forsyne isoleringspladen med specielle overfladelag, men denne metode har ikke fundet praktisk anvendelse, eftersom de lag, som skulle anvendes, var vandglas med tilsætninger af uorganiske stoffer. Metoden medfører en reduktion i isoleringsevnen og medfører stadig et højt forbrug af bitumen.Attempts have been made to eliminate the problems of heavy bitumen absorption by providing the insulating plate with special surface layers, but this method has not found practical application since the layers to be used were water glass with inorganic additives. The method results in a reduction in the insulation capacity and still leads to a high consumption of bitumen.

Formålet med opfindelsen er at tilvejebringe en isoleringsplade, der uden reduktion af isoleringsegenskaberne lader sig fastholde til en overflade med en bituminøs belægning uden stort forbrug af bitumen.The object of the invention is to provide an insulating plate which, without reducing the insulating properties, can be adhered to a surface with a bituminous coating without excessive consumption of bitumen.

Dette opnås ved, at isoleringspladerne er ejendommelige ved det i den kendetegnende del af krav 1 angivne.This is achieved by the fact that the insulating plates are peculiar to that of the characterizing part of claim 1.

Ved at fibrene i det uvævede tekstil i det væsentlige er placeret i et enkelt plan er opsugningsevnen begrænset.Because the fibers of the nonwoven fabric are substantially located in a single plane, the absorbency is limited.

Det synes som om, at blot der er udlagt en bitumenfilm, der har tilstrækkelig tykkelse til at "dække" tekstilet, opnås der en fyldestgørende klæbning, der ikke forbedres væsentligt ved en forøgelse af bitumenmængden. Ved en forøgelse af bitumen-mængden opsuges en del af bituminen i mineralulden og bidrager derved til at forøge sammenhæftningen mellem det uvævede lag 148121 2 og mineralulden, men anvendelsen af så store bitumenmængder er ved isoleringspladen ifølge opfindelsen hverken økonomisk eller nødvendig. Den tilsigtede virkning optræder kun i det angivne interval for tekstilets fladevægt, idet en forøget fladevægt medfører et forøget bitumenforbrug og en for lille fladevægt giver en ringe styrke i tekstilet. Det store binde-middelindhold i tekstilet giver dels styrke til tekstilet, dels sørger det for en god klæbeforbindelse til den øvrige isolering.It seems that just because a bitumen film is sufficiently thick to "cover" the fabric, an adequate adhesion is not obtained which is not substantially improved by increasing the amount of bitumen. By increasing the amount of bitumen, part of the bitumen is absorbed in the mineral wool, thereby contributing to increasing the bonding between the nonwoven layer 148121 2 and the mineral wool, but the use of such large amounts of bitumen in the insulating plate according to the invention is neither economical nor necessary. The intended effect occurs only in the stated range of the textile's surface weight, with an increased surface weight resulting in increased bitumen consumption and a too low surface weight giving a low strength in the textile. The high binder content of the textile gives strength to the textile and provides a good adhesive connection to the other insulation.

I henhold til opfindelsen indeholder det uvævede tekstil ca. 20 vægtprocent bindemiddel, idet denne mængde giver optimal udnyttelse af bindemidlet.According to the invention, the nonwoven fabric contains approx. 20% by weight of binder, this amount provides optimal utilization of the binder.

Laget af uvævet tekstil på overfladen af isoleringspla- 2 den kan ifølge opfindelsen have en fladevægt på 40 til 50 g/m for at opnå maksimal styrke af fastklæbningen til overfladen.According to the invention, the nonwoven textile layer on the surface of the insulating sheet may have a surface weight of 40 to 50 g / m to obtain maximum strength of the adhesive to the surface.

Opfindelsen omfatter tillige en fremgangsmåde til fremstilling af en isoleringsplade som angivet i krav 1, hvor pladen inden eller under passage gennem en opvarmningszone påføres et uvævet lag af mineralske fibre. Fremgangsmåden, der er ejendommelig ved det i den kendetegnende del af krav 4 angivne, muliggør, at det uvævede tekstil forenes med overfladen af isoleringspladen ved hjælp af den termohærdende harpiks. Desuden opnås der en meget jævn og plan overflade, som ligeledes medvirker til at reducere bitumenforbruget ved en fastklæbning af pladen, eftersom en manglende jævnhed af pladen automatisk vil forøge bitumenforbruget.The invention also encompasses a method of producing an insulating plate as claimed in claim 1, wherein the plate is applied, or during passage through a heating zone, to a nonwoven layer of mineral fibers. The method characterized by the characterizing part of claim 4 allows the nonwoven fabric to be joined to the surface of the insulating plate by the thermosetting resin. In addition, a very smooth and flat surface is obtained, which also contributes to reducing bitumen consumption by sticking to the plate, since a non-uniformity of the plate will automatically increase the bitumen consumption.

Opfindelsen skal i det følgende beskrives nærmere under henvisning til tegningen, på hvilken der er vist en udførelsesform.The invention will now be described in more detail with reference to the drawing, in which an embodiment is shown.

På tegningen viser: fig. 1 et snit gennem en isoleringsplade af mineraluld i henhold til opfindelsen, fig. 2 en anden udformning af en sådan plade fastgjort til en overflade, der skal isoleres, og fig. 3 viser i større skala en overfladedetalje af en isoleringsplade.In the drawing: FIG. 1 is a section through a mineral wool insulation board according to the invention; FIG. 2 shows another embodiment of such a plate attached to a surface to be insulated; and FIG. 3 shows on a larger scale a surface detail of an insulation plate.

På tegningen er der vist en isoleringsplade bestående af stenuld med isolerende mellemrum 3.The drawing shows an insulation plate consisting of stone wool with insulating gap 3.

Mineralulden er forbundet ved hjælp af en termohærdende harpiks, hvilken harpiks hærdes i en opvarmet zone med en temperatur mellem 140 og 170° C.The mineral wool is connected by a thermosetting resin, which resin is cured in a heated zone with a temperature between 140 and 170 ° C.

Overfladen 4 på normale, kendte isoleringsplader af mineraluld er meget ujævn, hvilket medfører, at når en sådan flade anbringes på en overflade 5, der skal isoleres, forbruges der et stort kvantum bitumen eller en bituminøs belægning 6. Der sker nemlig det, at bitumen absorberes i mineraluldspladen.The surface 4 of normal known mineral wool insulating plates is very uneven, which means that when such a surface is applied to a surface 5 to be insulated, a large amount of bitumen or bituminous coating 6 is consumed. absorbed in the mineral wool plate.

Opfindelsen har til formål at afhjælpe disse vanskeligheder ved påføreIse af et uvævet tekstil 7 til overfladen af mineraluldspladen. Dette lag 7 består fortrinsvis af et uvævet lag af glasfibre, hvilket lag har en vægt på 45 g/m og er fikseret ved hjælp af 20 vægtprocent formaldehydharpiks .The invention aims to alleviate these difficulties by applying a nonwoven fabric 7 to the surface of the mineral wool board. This layer 7 preferably consists of a nonwoven layer of glass fibers having a weight of 45 g / m and fixed by 20% by weight of formaldehyde resin.

På grund af påføringen af dette uvævede lag 7 forud for hærdningen af mineraluldpladen opnås det, at det uvævede lag klæber fast til pladen under hærdningen af den termohærdende harpiks.Due to the application of this nonwoven layer 7 prior to the curing of the mineral wool sheet, it is obtained that the nonwoven layer adheres to the sheet during the curing of the thermosetting resin.

Anbringelsen af glasfiberlaget har den fordel, at der opnås en meget jævn overflade på pladen, hvorved forbruget af bitumen kan reduceres betydeligt, samtidig med at man overraskende har konstateret, at bitumenen medvirker til sammenbindingen mellem det u-vævede lag og mineraluldspladen samtidig med fastholdelsen til overfladen, samtidig med at forbruget af bitumen nedsættes væsentligt.The application of the fiberglass layer has the advantage that a very smooth surface is obtained on the plate, whereby the consumption of bitumen can be significantly reduced, while surprisingly it has been found that the bitumen contributes to the bonding between the nonwoven layer and the mineral wool plate while maintaining the the surface while significantly reducing the consumption of bitumen.

Dette fremgår f.eks. af, at når der anvendes et uvævet 2 glastekstil, nedsættes forbruget af bitumen til 1-1,5 kg/m i 2 stedet for det normale kvantum på 2,5 - 3 kg/m .This is stated, for example. by using a nonwoven 2 glass fabric, the consumption of bitumen is reduced to 1-1.5 kg / m 2 instead of the normal quantity of 2.5 - 3 kg / m.

Om ønsket kan det uvævede lag af glasfiber armeres, hvorved modstandsevnen til lokale belastninger på isoleringspladen forøges betydeligt. Dette medfører en forøget modstand af isoleringen over for gående trafik.If desired, the nonwoven layer of fiberglass can be reinforced, thereby significantly increasing the resistance to local loads on the insulation plate. This results in increased resistance of the insulation to pedestrian traffic.

Det må forstås, at pladen også først kan hærdes og derefter glattes, hvorpå det uvævede lag påføres.It is to be understood that the plate can also first be cured and then smoothed, upon which the nonwoven layer is applied.
