Opfindelsen angår en fremgangsmåde til fremstilling af isoleringsplader sammensat af indbyrdes forbundne stavformede mineralfiberele-menter (i det følgende betegnet lameller), hvorved en smelte af mi neral fiberdannende udgangsmaterialer omdannes til fibre, som 5 tilføres et bindemiddel, og som bringes til at danne en fiberbane, der underkastes en højdekomprimering, og hvor fiberbanen opskæres i længderetningen til dannelse af lameller, der afskæres i ønskede længder, drejes 90° om deres længdeakse og sammenklæbes til dannelse af plader.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a process for producing insulating sheets composed of interconnected rod-shaped mineral fiber elements (hereinafter referred to as slats), wherein a melt of mineral fiber-forming starting materials is converted into fibers which are applied to a binder and produced to form a fiber web. , which are subjected to a height compression and where the fiber web is cut longitudinally to form slats cut to desired lengths, 90 ° is rotated about their longitudinal axis and glued to form sheets.

En fremgangsmåde af den i indledningen angivne art er beskrevet i DE 2307577 C3. Ved denne kendte fremgangsmåde omdannes smelten til fine mineral fibre ved udslyngning fra et eller flere hurtigt roterende spindehjul under samtidig tilførsel af et hærdeligt bindemiddel, og 15 de dannede fibre opfanges på et endeløst bånd i form af en fiberbane, hvori fibrene til dels er orienterede parallelt med baneoverfladen. Ved den kendte fremgangsmåde foretages en højdekomprimering og en længdeopskæring af fiberbanen i lameller og de dannede lameller drejes i 90* om deres længdeakse, hvorpå de således orien-20 terede lameller sammenklæbes til dannelse af et baneformet produkt, der derpå opskæres i ønskede længder til dannelse af pladeformede elementer. På grund af drejningen af lamellerne vil fibrene i de færdige plader hovedsageligt være orienterede i et plan vinkelret på pladeoverfladerne og der opnås derved plader med en betydelig 25 . stivhed og styrke vinkelret på pladeoverfladerne.A process of the kind set forth in the preamble is described in DE 2307577 C3. In this known process, the melt is converted into fine mineral fibers by ejecting from one or more rapidly rotating spinning wheels during the simultaneous application of a curable binder, and the fibers formed are trapped on an endless band in the form of a fiber web, the fibers being partially oriented in parallel. with the web surface. In the known method, a height compression and a length cut of the fiber web are made in slats and the formed slats are rotated in 90 ° about their longitudinal axis, whereupon the thus oriented slats are bonded to form a web shaped product which is then cut to desired lengths to form. of plate-shaped elements. Due to the rotation of the slats, the fibers in the finished sheets will be mainly oriented in a plane perpendicular to the plate surfaces, thereby obtaining sheets of considerable 25. stiffness and strength perpendicular to the plate surfaces.
Plader, som er fremstillet på den ovenfor beskrevne måde, er velegnede til mange anvendelser, men til visse anvendelser, f.eks. til udvendig isolering af tage og/eller facader samt til isolering af 30 gulve har pladerne ikke en tilstrækkelig stivhed eller styrke og/eller en for lav isoleringsevne.Plates made in the manner described above are suitable for many applications, but for certain applications, e.g. for exterior insulation of roofs and / or facades and for insulating 30 floors, the panels do not have sufficient stiffness or strength and / or insufficient insulation capacity.
Det har nu vist sig, at disse egenskaber kan forbedres væsentligt, således at pladerne kan anvendes til formål, hvortil de kendte 35 plader ikke er anvendelige, ved ifølge opfindelsen at anvende lameller, som efter højdekomprimeringen er blevet underkastet en langskomprimering enten før eller efter opskæringen.It has now been found that these properties can be greatly improved so that the plates can be used for purposes for which the known plates are not usable, by using slats which according to the invention have been subjected to longitudinal compression either before or after the cutting .
Ved anvendelsen af lameller fremstillet ud fra en fiberbane, der er 2When using slats made from a fiber web that is 2
DK 165926 BDK 165926 B
blevet højde- og langskomprimeret, er der opnået en forøgelse af arealstyrken på op til 60 % i forhold til lamel pi ader fremstillet ud fra fiberbaner, som ikke har været underkastet en sådan behandling.having been elevated and longitudinally compressed, an area strength of up to 60% has been achieved in relation to slat pads made from fiber webs which have not been subjected to such treatment.
5 Opfindelsen er baseret på den erkendelse, at der ved en langskompri mering, d.v.s. en stukning i længderetningen af en fiberbane, hvor fibrene har en hovedorienteringsretning, der er parallel med baneoverfladen, vil opstå en indre foldestruktur, hvor folderne strækker sig vinkelret på fiberbanens længderetning.The invention is based on the recognition that by a long compression, i.e. a longitudinal sectioning of a fibrous web, the fibers having a principal orientation direction parallel to the web surface, will result in an inner folding structure where the folds extend perpendicular to the longitudinal direction of the fibrous web.
10 Når en sådan bane længdeopskæres i lameller og lamellerne drejes 90° og sammenklæbes til dannelse af en lamel plade, vil hver lamel udvise en foldet lagstruktur, hvor folderne forløber vinkelret på lamel pladens hovedflader og derved giver lamel pladen en større stivhed og 15 styrke (arealstyrke) end i det tilfælde, hvor lamellerne er sammen sat af retlinede lag.When such a web is longitudinally cut into slats and the slats are rotated 90 ° and adhered to form a slat plate, each slat will exhibit a folded layer structure, the folds extending perpendicular to the main surfaces of the slat plate thereby giving the slat plate greater rigidity and strength ( area strength) than in the case where the slats are composed of rectilinear layers.
I stedet for at opnå en forøgelse af styrken kan det være ønskeligt at mindske rumvægten, idet dette kan medføre en forøgelse af isole-20 ringsevnen. Det er således kendt, at stenuldslamel pi ader med et indhold af perler, som er større end 63 /zm, på ca. 30% har optimal isoleringsevne ved en rumvægt på ca. 40 kg/m3.Instead of increasing the strength, it may be desirable to decrease the room weight, as this may increase the insulation capacity. Thus, it is known that stone wool slab pea with a content of beads greater than 63 µm, of approx. 30% have optimum insulation capacity at a room weight of approx. 40 kg / m3.
Det er kendt, jvf. DE 2307577, at en relativ tyk mi neral fiberbane 25 kan dannes direkte nemlig ved at opsamle de ud fra smelten dannede fibre på et transportbånd. Det er ligeledes kendt, jvf. DE 3501897 Al, at en fiberbane kan fremstilles ved først at fremstille en relativt tynd primærbane og derpå at dublere primærbanen til dannelse af en sekundær relativt tyk fiberbane omfattende delvis over-30 lappende lag af primærbanen.It is known, according to DE 2307577, that a relatively thick mineral fiber web 25 can be formed directly, namely, by collecting the fibers formed from the melt on a conveyor belt. It is also known, according to DE 3501897 A1, that a fiber web can be made by first producing a relatively thin primary web and then duplicating the primary web to form a secondary relatively thick fiber web comprising partially overlapping layers of the primary web.
I en direkte dannet fiberbane vil fibrene have varierende orienteringsretninger, men ved at underkaste en sådan bane en højdekomprimering, vil der ske en delvis omlejring af fibrene, således at de 35 får en dominerende orienteringsretning, som er parallel med baneoverf1aden.In a directly formed fiber web, the fibers will have varying orientation directions, but by subjecting such web to height compression, partial fibers will be rearranged to give a dominant orientation direction parallel to the web surface.
Når en fiberbane skal dubleres, opsamles fibrene i form af et tyndt fiberlag, f.eks. med en vægt på 0,3 kg/m på et hurtigtløbende 3When a fiber web is to be doubled, the fibers are collected in the form of a thin fiber layer, e.g. with a weight of 0.3 kg / m on a fast running 3
DK 165926BDK 165926B
transportbånd, f.eks. med en hastighed på 130 m/min. Når fibrene opsamles på denne måde, vil de lejre sig på transportbåndet i retninger, som er parallelle med baneoverfladen og med en overvægt af fibre lejret parallel med båndets bevægelsesretning. Dette 5 indebærer, at fiberbanen får en trækstyrke, der er ca. dobbelt så stor i fiberbanens længderetning, som i dens tværretning. Den sekundære fiberbane dannes ved, at pendulbånd udlægger den tynde primærbane fortrinsvis på tværs af sekundærbanens længderetning i et antal lag, f.eks. 20, idet antallet af lag bestemmes af den ønskede 10 areal vægt for sekundærbanen.conveyor belts, e.g. at a speed of 130 m / min. When the fibers are collected in this way, they will settle on the conveyor belt in directions parallel to the web surface and with an overweight of fibers stored parallel to the direction of movement of the belt. This 5 implies that the fiber web has a tensile strength of approx. twice as long in the longitudinal direction of the fiber web as in its transverse direction. The secondary fiber web is formed by the shuttle band projecting the thin primary web preferably across the longitudinal direction of the secondary web in a plurality of layers, e.g. 20, the number of layers being determined by the desired area of weight for the secondary web.
I den dublerede bane vil der være en overvægt af fibre, der ligger på tværs af banen, når lagene af primærbanen ligger på tværs af sekundærbanen.In the duplicate web there will be an overweight of fibers lying across the web as the layers of the primary web are transverse to the secondary web.
1515
Formålet med at dublere en fiberbane er normalt at opnå en sekundærbane med en relativ stor tykkelse og med en ringe densitetsvariation i tværretningen.The purpose of doubling a fiber web is usually to obtain a secondary web having a relatively large thickness and with a slight density variation in the transverse direction.
20 Ved fremgangsmåden ifølge opfindelsen anvendes fortrinsvis lameller fremstillet ud fra en dubleret fiberbane med et lagantal på fra 4 til 25 og med en fladevægt på fra 1 til 8 kg/m .20 In the method according to the invention, slats made from a doubled fiber web preferably having a layer number of from 4 to 25 and having a surface weight of from 1 to 8 kg / m are preferably used.
Der opnås en særlig stor trykstivhed af plader dannet af lameller, 25 der er opskåret i lameller i sekundærbanens længderetning, og derpå drejet 90* om deres længdeakse, fordi de fibre, der i overvejende grad var orienterede på tværs af sekundærbanen, vil ligge vinkelret på pladeplanet.A particularly high compressive stiffness is obtained from sheets formed by slats 25 which are cut into slats in the longitudinal direction of the secondary web and then rotated 90 ° about their longitudinal axis, because the fibers which are predominantly oriented across the secondary web will be perpendicular to plate plane.
30 Ved at langskomprimere fiberbanen, inden lamellerne drejes 90*, øges de færdige lamellers trykstyrke og ovennævnte forøgelse af stivheden og forøgelsen af trykstyrken synes at undestøtte hinanden, hvilket viser sig ved, at de to foranstaltninger øjensynligt giver en samlet virkning, der er større end enkeltvirkningerne.30 Longitudinally compressing the fiber web before turning the slats 90 * increases the compressive strength of the finished slats and the above-mentioned increase in stiffness and increase in compressive strength appear to support each other, as evidenced by the fact that the two measures apparently produce a combined effect greater than single effects.

Fremgangsmåder til langskomprimering af fiberbaner er i og for sig kendte. Ved en foretrukken kendt fremgangsmåde, jvf. CH patentskrift nr. 620861, indføres en mi neral fiberbane i mellemrummet mellem to parallelle transportbånd, der fremføres med en hastighed Vj og derpå 4Methods for longitudinal compression of fiber webs are known per se. In a preferred method known in accordance with CH patent specification No. 620861, a mineral fiber web is introduced into the gap between two parallel conveyors conveyed at a speed V
DK 165926 BDK 165926 B
i mellemrummet mellem to yderligere transportbånd, der fremføres med en hastighed der er mindre end Vj. Afhængigt af forholdet mellem og V2 opnås der en større eller mindre langskomprimering af fiberbanen. Forholdet mellem og vælges således, at der ved 5 langskomprimeringen dannes folder, der strækker sig på tværs af banens længderetning. Ved en anden foretrukken fremgangsmåde, jvf.in the space between two additional conveyors conveyed at a speed less than Vj. Depending on the ratio of V2, greater or less longitudinal compression of the fiber web is achieved. The ratio of and selected such that at longitudinal compression folds are formed which extend across the longitudinal direction of the web. In another preferred method, cf.
US patentskrift nr. 2500690, foretages langskomprimering ved hjælp af en række efter hinanden anbragte valsesæt, hvor valserne roterer med en hastighed, der aftager i fiberbanens længderetning.U.S. Patent No. 2500690, longitudinal compression is performed by a series of successively arranged roller sets, the rollers rotating at a speed decreasing in the longitudinal direction of the fiber web.
1010
Det foretrækkes, at langskomprimere fiberbanen, inden den opskæres i lameller, men langskomprimeringen kan også udføres efter opskæringen i lameller.It is preferred to longitudinally compress the fiber web before cutting it into slats, but longitudinal compression can also be performed after cutting into slats.
15 Til brug ved fremgangsmåden ifølge opfindelsen foretrækkes lameller fremstillet ud fra fiberbaner, der er langskomprimeret i et forhold på fra 1,5:1 til 4:1.For use in the method of the invention, slats made from fiber webs which are longitudinally compressed in a ratio of 1.5: 1 to 4: 1 are preferred.
Langskomprimeringen skal som nævnt ske efter højdekomprimeringen, og 20 ved anvendelse af et varmehærdeligt bindemiddel foretages den inden fiberbanen indføres i en hærdeovn.As mentioned, the longitudinal compression must be done after the height compression, and 20 using a heat-curable binder, it is done before the fiber web is introduced into a curing oven.
Fremgangsmåder til højdekomprimering af en fiberbane er også kendte.Methods for height compression of a fiber web are also known.
Ved en sådan kendt fremgangsmåde indføres fiberbanen, som skal 25 højdekomprimeres, i mellemrummet mellem valserne i en række valsesæt, hvor afstanden mellem valserne i valsesættende aftager i fiberbanens bevægelsesretning.In such a known method, the fiber web, which must be height compressed, is introduced into the space between the rollers in a series of roll sets, the distance between the rollers in roll setting decreasing in the direction of movement of the fiber web.
Til brug ved fremgangsmåden ifølge opfindelsen foretrækkes det at 30 anvende lameller fremstillet ud fra en fiberbane, som er blevet højdekomprimeret i et forhold på fra 3:1 til 6:1.For use in the method of the invention, it is preferred to use slats made from a fiber web which has been height compressed in a ratio of from 3: 1 to 6: 1.
Opskæringen af fiberbanen foretages fortrinsvis ved hjælp af save, der kan have form som stiksave, jvf. DE 2307577 eller rundsave, jvf.The cutting of the fiber web is preferably done by means of saws which can take the form of jigsaws, cf. DE 2307577 or circular saws, cf.
35 SE fremlæggelsesskrift nr. 441764 og DE 2032624.35 SE disclosure no. 441764 and DE 2032624.
Ved en foretrukket udførelsesform for fremgangsmåden ifølge opfindelsen opskæres de stavformede fiberelementer i ønskede længder, inden de drejes 90° og sammensættes til lamel pi ader. Dette kan 5In a preferred embodiment of the method according to the invention, the rod-shaped fiber elements are cut to desired lengths before being turned 90 ° and assembled into slats. This can 5

f.eks. ske i forbindelse med at de afskårne lameller overføres fra et transportbånd, hvorpå de fremføres i lamellernes længderetning til et andet transportbånd, der bevæger sig vinkelret på det første, og hvorpå lamellerne fremføres i en retning, som er vinkelret på 5 deres længderetning.eg. This is done in connection with the cut slats being transferred from a conveyor belt, whereupon they are conveyed in the longitudinal direction of the slats to another conveyor belt which is perpendicular to the first one and then the slats are fed in a direction perpendicular to their longitudinal direction.
Denne udførelsesform udmærker sig ved, at det hertil krævede apparatur ikke er særligt pladskrævende.This embodiment is characterized in that the apparatus required for this is not very space consuming.
10 Drejningen af lamellerne kan i stedet ske under opskæringen i lameller, f.eks. som beskrevet i DE 2307577 eller DE 2032624.Instead, the slats can be rotated during cutting into slats, e.g. as described in DE 2307577 or DE 2032624.
De korrekt orienterede lameller til dannelse af en lamel plade kan sammenklæbes, fortrinsvis ved hjælp af et bindemiddel, der påføres 15 fiberbanens overside og eventuelt underside, og fortrinsvis inden den opskæres i lameller.The properly oriented slats to form a slat plate may be bonded, preferably by means of a binder applied to the upper and possibly underside of the fiber web, and preferably before being cut into slats.
Det er dog ikke nødvendigt at tilføre et yderligere bindemiddel, idet bindemidlet, der er tilført fibrene i forbindelse med deres 20 dannelse også befinder sig i overfladen af lamellerne og kan være tilstrækkelig til at sammenklæbe lamellerne, hvis de under hærdningen af bindemidlet i hærdeovnen holdes tæt sammen, jvf. DK patentansøgning nr. 3526/75.However, it is not necessary to add an additional binder, since the binder fed to the fibers in connection with their formation is also in the surface of the slats and may be sufficient to adhere the slats if they are held tightly during curing of the binder in the curing oven. together, cf. DK Patent Application No. 3526/75.
25 Hvis fibrene er blevet tilført et varmehærdeligt bindemiddel i forbindelse med deres dannelse og der til sammenklæbning af lamellerne ligeledes anvendes et varmehærdeligt bindemiddel, kan hærdningen af bindemidlerne ske på én gang ved at føre de korrekt orienterede og sammenstillede lameller gennem en hærdeovn, hvori de 30 opvarmes til hærdetemperatur, der ved anvendelse af phenol formaldehydharpikser som bindemiddel, fortrinsvis er mellem 210 og 260*C.If the fibers have been applied to a heat-curable binder in conjunction with their formation and a heat-curable binder is also used to cure, the curing of the binders can be effected at once by passing the properly oriented and assembled slats through a curing furnace wherein heated to cure temperature which, using phenol formaldehyde resins as a binder, is preferably between 210 and 260 ° C.
Bindemidlet til sammenklæbning af lamellerne kan dog også tilføres efter, at fiberbanen/lamellerne er blevet opvarmet i en hærdeovn til 35 hærdning af et ved fibrenes dannelse tilført varmehærdende bindemiddel .However, the binder for bonding the slats may also be applied after the fiber web (s) has been heated in a curing furnace to cure a heat-curing binder applied during formation of the fibers.
Ved at foretage en sådan tilførsel af et bindemiddel efter hærdeovnen, kan der anvendes andre bindemidler end varmehærdendeBy applying such a binder after the curing furnace, binders other than heat curing can be used.

Opfindelsen vil i det følgende blive beskrevet nærmere under henvisning til tegningen, som skematisk viser et anlæg til udøvelse af 5 fremgangsmåden ifølge opfindelsen.The invention will be described in more detail below with reference to the drawing, which schematically shows a system for carrying out the method according to the invention.
På tegningen betegner 1 en ovn til fremstilling af en mineral -fiberdannende smelte, som via et smelteudløb 2 tilføres en spinder 3 med fire hurtigt roterende spindehjul 4. Samtidig med at der indfø-10 res smelte på spindehjulenes ydersider og udsprøjtes bindemiddel, føres der en kraftig gasstrøm hen over overfladerne i spindehjulenes aksialretning. Herved dannes der fibre 5, der opfanges på et endeløst perforeret transportbånd 6, som understøttes af tre valser 7, hvoraf en drives med ikke viste drivorganer. Der dannes herved en 15 fiberbane 8 (primærbanen), som ved hjælp af et yderligere endeløst transportbånd 9 indføres i mellemrummet mellem to pendul bånd 10 og 11, hvis nederste ender er anbragt svingbart i en retning, der er vinkelret på fremføringsretningen af et yderligere endeløst transportbånd 12, som understøttes af to valser 13, hvoraf den ene drives 20 af ikke viste drivorganer.In the drawing, 1 denotes a furnace for producing a mineral fiber forming melt which is supplied via a melt outlet 2 to a spinner 3 with four fast rotating spinning wheels 4. At the same time as the melt is introduced on the outside of the spinning wheels and binder is injected, a high gas flow across the surfaces in the axial direction of the spinning wheels. Hereby fibers 5 are formed which are intercepted on an endless perforated conveyor belt 6, which is supported by three rollers 7, one of which is driven with drive means not shown. Hereby a fiber web 8 (the primary web) is formed which is introduced by means of a further endless conveyor belt 9 into the space between two pendulum bands 10 and 11, the lower ends of which are pivotally arranged in a direction perpendicular to the direction of conveyance of a further endless conveyor belt 12, which is supported by two rollers 13, one of which is driven 20 by drive means not shown.
Amplituden for svingningen af den nederste del af pendul båndene 10 og 11 svarer til bredden af transportbåndet 12, og der dannes herved på båndet 12 en dubleret fiberbane 14 af delvis overlappende fiber-25 lag 8.The amplitude of the oscillation of the lower portion of the pendulum bands 10 and 11 corresponds to the width of the conveyor belt 12, thereby forming on the belt 12 a doubled fiber web 14 of partially overlapping fiber layers 8.
Fiberbane 14 føres derpå ind i en højdekomprimeringssektion bestående af tre sæt samvirkende valser 15, 16 og 17, hvor afstanden mellem valserne i valsesættet aftager i fiberbanens længderetning.Fiber web 14 is then fed into a height compression section consisting of three sets of cooperating rollers 15, 16 and 17, where the distance between the rollers in the roller set decreases in the longitudinal direction of the fiber web.
30 Herpå føres fiberbanen 14 ind i en langskomprimeringssektion, der ligeledes består af tre valsesæt 18, 19 og 20, hvor valserne i valsesættet roterer med samme rotationshastighed, hvilken rotationshastighed er lavere end rotationshastigheden af valsesættene 15, 16 og 17.30 The fiber web 14 is then introduced into a longitudinal compression section, which also consists of three roller sets 18, 19 and 20, with the rollers in the roller set rotating at the same rotational speed, which rotational speed is lower than the rotational speed of the rolling sets 15, 16 and 17.
Den langskomprimerede fiberbane føres derpå ind i en hærdeovn 21, hvori den opvarmes til en tilstrækkelig høj temperatur til at hærde bindemidlet og til fiksering af fibrene i forhold til hinanden.The long compressed fiber web is then fed into a curing furnace 21 in which it is heated to a sufficiently high temperature to cure the binder and to fix the fibers relative to each other.

Efter hærdeovnen opskæres den varmebehandlede fiberbane 14 i længderetningen ved hjælp af save 22. Herved dannes et antal lameller 23, som derpå afskæres på tværs ved hjælp af en tværgående sav 24.After the curing furnace, the heat-treated fiber web 14 is longitudinally cut by saws 22. Hereby a number of slats 23 are formed, which are then cut transversely by means of a transverse saw 24.
De således afskårne lameller 23 drejes derpå 90* og sammenstilles 5 til dannelse af et pladeformet element 25 på et transportbånd 26 samtidig med, at kontaktfladerne ved hjælp af et ikke vist påfø ringsapparat påføres et bindemiddel til sammenklæbning af lamellerne 23.The slats 23 thus cut are then rotated 90 * and assembled 5 to form a plate-shaped element 25 on a conveyor belt 26, at the same time as the contact surfaces are applied by means of a not shown applicator a binder for bonding the slats 23.
10 Som antydet på tegningen forløber de af primærbanen 8 dannede fiberlag i det væsentlige vinkelret på overfladen af det endelige pladeformede element, og da de samtidig er foldede, har de en særlig stor modstandsdygtighed mod sammentrykning.As indicated in the drawing, the fiber layers formed by the primary web 8 extend substantially perpendicular to the surface of the final plate-shaped member and, when folded at the same time, have a particularly high compressive resistance.
15 I stedet for at sammenklæbe lamellerne kan de forbindes indbyrdes med forbindelsesorganer i form af f.eks. strimler, snore, vlies eller papir på den ene eller begge sider af pladerne.Instead of bonding the slats, they can be interconnected with connecting members in the form of e.g. strips, cords, fleece or paper on one or both sides of the plates.
