Description

Oblasť technikyTechnical field

Vynález sa týka pravouhlej izolačnej dosky obsahujúcej vrstvu minerálnych vlákien, vytvorenú z jedného celku minerálneho vláknitého materiálu, kde sú minerálne vlákna navzájom spojené spojivom, pričom vlákna vo vrstve minerálnych vlákien sú prevažne umiestnené v rovinách, v podstate kolmých na rovinu dosky, a doska je ľahšie stlačiteľná v pozdĺžnom alebo priečnom smere, ako v druhom z obidvoch smerov.The invention relates to a rectangular insulating board comprising a mineral fiber layer formed from one unit of mineral fiber material, wherein the mineral fibers are bonded together by a binder, the fibers in the mineral fiber layer being predominantly located in planes substantially perpendicular to the plane of the plate and lighter compressible in longitudinal or transverse direction, as in the other of both directions.

Doterajší stav technikyBACKGROUND OF THE INVENTION

V súčasnosti známe izolačné dosky, používané na izoláciu stropov, stien a striech sú ľahko tvarovateľné a stlačiteľné, v dôsledku čoho sa ľahko ukladajú na miesto montáže. Dosky sa tak môžu montovať úplne alebo čiastočne bez rezania, ktoré je nežiaduce, pretože je pracné a uvoľnené vlákna sa pri ňom dostávajú do okolitého prostredia.The currently known insulating boards used to insulate ceilings, walls and roofs are easily deformable and compressible, making them easy to place at the installation site. Thus, the boards can be mounted wholly or partially without cutting, which is undesirable because it is laborious and the released fibers get into the environment.

K pomerne značnému uvoľňovaniu vlákien do okolitého prostredia však dochádza pri týchto izolačných doskách aj pri ich tvarovaní a stlačovaní, vlákna sa spolu so vzduchom vytlačovaným z dosky dostávajú do okolitého priestoru a pretože sa izolačné dosky často montujú v pomerne malých a obmedzených priestoroch, môže koncentrácia vlákien vo vzduchu, ktorý stavební robotníci vdychujú, dosiahnuť nežiaducich vysokých hodnôt.However, relatively high release of fibers into the environment occurs with these insulating boards as well as during their shaping and compression, the fibers, together with the air extruded from the board, enter the surrounding space and because the insulating boards are often mounted in relatively small and confined spaces, in the air that construction workers inhale, achieve undesirable high values.

Na zamedzenie tohto nežiaduceho efektu bolo preto navrhnuté uzavrieť dosku do voľnej, igelitovej vrecovitej obálky. Toto riešenie sa však ukázalo ako nedostatočné a nevhodné.Therefore, to avoid this undesirable effect, it has been proposed to enclose the board in a loose, plastic bag envelope. However, this solution proved to be insufficient and inappropriate.

Podstata vynálezuSUMMARY OF THE INVENTION

Uvedený cieľ sa dosiahne pravouhlou izolačnou doskou, tvarovo prispôsobiteľnou tvaru izolovanej plochy, pozostávajúcou z vrstvy minerálnych vlákien, oddeliteľnej od celistvého minerálneho vláknitého materiálu a majúcou svoje minerálne vlákna jednako navzájom spojené spojivom, a jednako prevažne usporiadané kolmo na hlavné povrchy dosky, na zaistenie namáhavejšej stlačiteľnosti dosky v smeroch kolmých na jej hlavné povrchy ako v smeroch na tieto smery kolmých, podľa tohto vynálezu, ktorého podstata spočíva v tom, že aspoň obidva jej hlavné povrchy sú vybavené vzduch priepustnou krycou vrstvou, ktorá má odpor vzduchu menší ako 100 mm vodného stĺpca.This object is achieved by a rectangular insulating plate, conformable to the shape of the insulated surface, consisting of a layer of mineral fibers detachable from a solid mineral fiber material and having their mineral fibers connected to each other by a binder, but predominantly arranged perpendicular to the main surfaces of the plate; the board in directions perpendicular to its main surfaces as in directions perpendicular to these directions, according to the present invention, characterized in that at least both of its main surfaces are provided with an air permeable covering having an air resistance of less than 100 mm water column.

Podstatou izolačnej dosky je tiež to, že oddelene vytvorená vzduch priepustná krycia vrstva jc spojená s vrstvou minerálnych vlákien pomocou adhezívnej vrstvy a že adhezívna vrstva má tvar pásov, prúžkov alebo radov bodiek, usporiadaných priečne proti jednému zo smerov, v ktorom jc doska ľahko stlačiteľná.It is also an object of the insulating board that the separately formed air permeable cover layer is connected to the mineral fiber layer by means of an adhesive layer and that the adhesive layer is in the form of strips, strips or dots of rows arranged transversely opposite one of the directions in which the board is easily compressible.

Za podstatné pre izolačnú dosku je nutné považovať aj to, že adhezívna vrstva má podobu vzduch priepustnej celistvej lepiacej vrstvy a že spojivom je tepelne vytvrditeľné spojivo.It is also essential for the insulating board that the adhesive layer is in the form of an air permeable, solid adhesive layer and that the binder is a thermosetting binder.

Izolačná doska poskytuje tú výhodu, že v dôsledku pripojenia krycej vrstvy k doske sa počas jej rezania dostanú do okolia iba uvoľnené vlákna z miesta rezu a nie z celého povrchu dosky, ako je to pri doske s voľnou igelitovou vrecovitovou obálkou, ktorá je pri rezaní roztrhnutá alebo stiahnutá.The insulating board provides the advantage that, due to the attachment of the cover layer to the board, only loose fibers from the cutting point get into the environment during cutting, and not the entire board surface, as is the case with a loose plastic bag envelope which is torn during cutting or downloaded.

S izolačnou doskou vybavenou krycou vrstvou sa tiež lepšie manipuluje, takže sa znižuje na minimum riziko prí padného roztrhnutia krycej vrstvy z materiálu z minerálnych vlákien.An insulating board provided with a cover layer is also easier to handle, so that the risk of tearing the cover layer of mineral fiber material to a minimum is minimized.

Ďalšou výhodou izolačnej rohože podľa tohto vynálezu je to, že krycia vrstva spojená s doskou prepožičiava doske zvýšenú tuhosť v ohybe, keď je doska umiestnená tak, že nie je celá podopretá, takže krycia vrstva je napnutá, napríklad keď je umiestená medzi krokvami v trochu stlačenom stave, alebo keď je umiestená tak, žc konce dosky spočívajú na stropných nosníkoch, takže sa doska prehýba vlastnou váhou. V týchto prípadoch krycia vrstva slúži k zníženiu stupňa prehnutia dosky do tej miery, do akej je krycia vrstva napnutá, alebo do akej sa napne pri počiatočnom prehnutí dosky.Another advantage of the insulating mat according to the invention is that the cover layer attached to the board imparts increased bending rigidity to the board when the board is positioned so that it is not entirely supported, so that the cover layer is stretched, for example when placed between the rafters or when it is positioned such that the ends of the board rest on the ceiling beams, so that the board bends under its own weight. In these cases, the cover layer serves to reduce the degree of deflection of the board to the extent that the cover layer is stretched or stretched when the board is initially deflected.

Izolačná doska je výhodná tiež tým, že poskytuje oveľa lepší pocit na omak, ako nepokrytá doska.An insulating board is also advantageous in that it provides a much better feel to the hand than an uncoated board.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Izolačná doska podľa tohto vynálezu je vytvorená z jedného celku materiálu z minerálnych vlákien (oproti množstvu tyčovitých jednotiek používaných v doteraz známych doskách), pričom celá na obidvoch jej hlavných povrchoch upravená krycia vrstva je priepustná pre vzduch a je stlačiteľná v smeroch kolmých na jej hlavné povrchy ako v smeroch na tieto smery kolmom.The insulating board according to the invention is formed of one unit of mineral fiber material (as opposed to the number of rod units used in the prior art sheets), wherein the entire covering surface of both its main surfaces is air permeable and compressible in directions perpendicular to its main surfaces. as perpendicular to these directions.

Krycia vrstva má odpor vzduchu menši ako 100 mm vodného stĺpca, pričom výhodne má odpor vzduchu menší ako 50 mm vodného stĺpca, a v najvýhodnejšom uskutočnení potom má odpor vzduchu menši ako 25 mm vodného stĺpca.The cover layer has an air resistance of less than 100 mm water column, preferably having an air resistance of less than 50 mm water column, and most preferably has an air resistance of less than 25 mm water column.

Odpor vzduchu materiálu krycej vrstvy je pritom definovaný ako strata tlaku v materiáli meraná v mm vodného stĺpca, pričom prúd vzduchu s rýchlosťou 0,186 m/s je privádzaný proti materiálu v smere kolmom na jeho rovinu.The air resistance of the coating material is defined as the pressure loss in the material measured in mm of the water column, the air flow at a speed of 0.186 m / s being supplied against the material in a direction perpendicular to its plane.

Materiál krycej vrstvy by mal mať takú priepustnosť vzduchu, aby rýchlosť stlačenia dosky prevádzaného v súvislosti s jej použitím nebola v porovnaní s nepokrytou doskou znateľne znížená, a aby dovoľovala strojové balenie dosky pod tlakom.The coating material should have an air permeability such that the compression rate of the board transferred in connection with its use is not appreciably reduced compared to the uncoated board and allows the machine to be packaged under pressure.

Materiál z minerálnych vlákien používaný na dosku podľa vynálezu môže byť vyrábaný premenou minerálnej taveniny na vlákna, pridaním spojiva k uvedeným vláknam a ich tvarovaním na vláknové rúno, ktoré pripadne môže byť podrobené vertikálnemu stlačeniu na usporiadanie vlákien v rovinách paralelných s povrchom vláknového rúna, a nasledujúcim podrobením vláknového rúna pozdĺžnemu stlačeniu na získanie vláknového rúna, v ktorom sú vlákna prevažne umiestené v rovinách v podstate kolmých na rovinu dosky.The mineral fiber material used for the board according to the invention can be produced by converting the mineral melt into fibers, adding a binder to said fibers and shaping them into a fiber web, which optionally can be subjected to vertical compression to arrange the fibers in planes parallel to the fiber web surface, and subjecting the fiber web to longitudinal compression to obtain a fiber web in which the fibers are predominantly positioned in planes substantially perpendicular to the plane of the plate.

Toto vláknové rúno je ľahšie stlačiteľné v pozdĺžnom smere, ako v smere kolmom a priečnom. V závislosti od toho, či je požadované vyrobiť dosku s maximálnou stlačiteľnosťou v priečnom smere alebo v pozdĺžnom smere, reže sa vláknové rúno tak, že pozdĺžny smer dosky zodpovedá priečnemu, resp. pozdĺžnemu smeru vláknového rúna.This fiber web is easier to compress in the longitudinal direction than in the perpendicular and transverse directions. Depending on whether it is desired to produce a board with maximum compressibility in the transverse direction or in the longitudinal direction, the fiber web is cut so that the longitudinal direction of the board corresponds to the transverse or longitudinal direction. the longitudinal direction of the fiber web.

Pri uvedenom spôsobe výroby sa výhodne používa tepelne vytvrditeľné spojivo, pričom kolmé a pozdĺžne stlačenie sa uskutočňuje pred vystavením vláknového rúna tepelnému spracovaniu na vytvrdenie spojiva. Uvedený spôsob výroby je opísaný napr. v CH-620.861.Preferably said thermally curable binder is used in said manufacturing process, wherein the perpendicular and longitudinal compression is performed before the fibrous web is subjected to a heat treatment to cure the binder. Said production method is described e.g. in CH-620,861.

Alternatívny spôsob výroby materiálu z minerálnych vlákien, vhodný pre dosky podľa vynálezu, spočíva v skladaní rúna z materiálu z minerálnych vlákien, v ktorom sú vlákna umiestnené v rovinách paralelných s rovinou rúna, do záhybov tiahnucich sa paralelne s priečnym smerom rúna.An alternative method of making the mineral fiber material suitable for the boards of the invention consists in folding the web of mineral fiber material in which the fibers are located in planes parallel to the plane of the web into folds extending parallel to the transverse direction of the web.

Záhyby môžu byť napríklad tvarované dopravovaním rúna cez spolupracujúcu dvojicu dopravných pásov, ktoré pracujú tak, že dopravné pásy majúce pevný vzájomný rozstup sa uvádzajú na výstupnom konci do vertikálneho kývavého pohybu s konštantnou amplitúdou. Týmto spôsobom je tvarované vlnité rúno, ktoré sa dopravuje cez dve dvojice za sebou umiestených, spolupracujúcich dopravných pásov, pričom druhá dvojica je poháňaná pomalšie ako prvá dvojica, čím nastáva pozdĺžne stlačenie rúna na vytvorenie skladaného rúna. Tento spôsob výroby je opísaný napr. v DE-A 35 22 237.For example, the pleats may be formed by conveying the web through a cooperating pair of conveyor belts which operate such that the conveyor belts having a fixed spacing between them at the outlet end move vertically with a constant amplitude. In this way, a corrugated web is formed which is conveyed through two pairs of successive, cooperating conveyor belts, the second pair being driven more slowly than the first pair, thereby causing longitudinal compression of the web to form a pleated web. This production method is described e.g. in DE-A 35 22 237.

Minerálnymi vláknami sú tu vlákna z minerálnej vlny, sklené vlákna, troskové vlákna a podobne umelé vlákna, vyrobené z minerálnych východiskových materiálov.The mineral fibers herein are mineral wool fibers, glass fibers, slag fibers and the like of artificial fibers made from mineral starting materials.

Minerálny vláknitý materiál sa výhodne skladá z vlákien minerálnej vlny a výhodne má hustotu zodpovedajúcu hmotnosti medzi 15 a 60 kg/m3.The mineral fiber material preferably consists of mineral wool fibers and preferably has a density corresponding to a weight of between 15 and 60 kg / m 3 .

Pre materiál zo sklených vlákien je merná hmotnosť výhodne medzi 10 a 60 kg/m3.For a glass fiber material, the density is preferably between 10 and 60 kg / m 3 .

Ako spojivo môže byť použité akékoľvek spojivo, obvykle používané vo výrobe výrobkov z minerálnych vlákien. Ničmenej výhodne sa používajú modifikované alebo nemodifikované fenolové živice, ako rezol alebo novolak.Any binder commonly used in the manufacture of mineral fiber products may be used as the binder. However, modified or unmodified phenolic resins such as resol or novolak are preferably used.

Pri izolačnej doske podľa tohto vynálezu je oddelene vytvorená vzduch priepustná krycia vrstva, spojená s vrstvou minerálnych vlákien pomocou adhezívnej vrstvy, pričom adhezívna vrstva má tvar pásov, prúžkov alebo rad bodiek, usporiadaných priečne proti jednému zo smerov, v ktorom je doska ľahko stlačiteľná.In the insulating board according to the invention, a separately air permeable cover layer is connected to the mineral fiber layer by means of an adhesive layer, wherein the adhesive layer is in the form of strips, strips or a series of dots arranged transversely opposite one of the directions in which the board is easily compressible.

Adhezívna vrstva môže mať aj podobu vzduch priepustnej celistvej lepiacej vrstvy.The adhesive layer may also be in the form of an air permeable, solid adhesive layer.

Krycia vrstva môže byť aplikovaná priamo na materiál z minerálnych vlákien, napríklad striekaním, ako je opísané napr. v medzinárodnej prihláške PCT/DK93/00064.The cover layer may be applied directly to the mineral fiber material, for example by spraying, as described e.g. in International Application PCT / DK93 / 00064.

Alternatívne môže byť krycia vrstva vyrábaná zvlášť a následne spojovaná s materiálom z minerálnych vlákien pomocou vrstvy lepidla, tavením/zváraním alebo šitím.Alternatively, the cover layer may be produced separately and subsequently bonded to the mineral fiber material by means of an adhesive layer, by melting / welding or sewing.

Krycia vrstva je výhodne vytvorená z netkaného organického alebo anorganického materiálu. Príklady použiteľných materiálov sú materiály z organických umelých vlákien, ako z polyetylénu, polypropylénu, nylonu a polyesteru. Krycia vrstva môže byť tvorená sieťovinou z týchto vlákien, napríklad sieťovinou s hmotnosťou medzi 5 až 100 g/m2.The cover layer is preferably formed of a nonwoven organic or inorganic material. Examples of useful materials are organic synthetic fiber materials such as polyethylene, polypropylene, nylon, and polyester. The cover layer may consist of a web of these fibers, for example a web of between 5 and 100 g / m 2 .

Použiteľné sú tiež netkané krycie vrstvy vytvorené z prírodných vlákien, ako vlákien celulózy, ľanu, kokosu, konopy a podobne. Pre krycie vrstvy je tiež možné použiť výrobky z modifikovanej celulózy, ako je napr. viskóza.Also useful are nonwoven coverings formed from natural fibers such as cellulose, flax, coconut, hemp and the like. Modified cellulose products, such as e.g. viscose.

Medzi príklady použiteľných netkaných anorganických materiálov môže byť uvedená aj sieťovina zo sklených vlákien s hmotnosťou medzi 10 až 100 g/m2, vytvorená zo sklených vlákien, majúcich hrúbku asi 5 až 13 pm.Examples of useful non-woven inorganic materials include glass fiber webs of between 10 and 100 g / m 2 , made of glass fibers having a thickness of about 5 to 13 µm.

Krycia vrstva môže byť tvorená tiež zmesami alebo kombináciami jedného alebo viac uvedených materiálov.The cover layer may also consist of mixtures or combinations of one or more of the aforementioned materials.

Miesto netkaných materiálov môžu byť použité ako materiál krycej vrstvy perforované fólie, ako polyetylénová alebo polypropylénová fólia majúca hmotnosť od 10 do 150 g/m2, alebo kovová fólia, ako napríklad hliníková fólia. Perforovaná fólia môže byť vo forme laminátu vrátane laminátu skladajúceho sa z plastovej fólie a papierovej vrstvy alebo plastovej fólie a kovovej fólie.Instead of nonwoven materials, a perforated film, such as a polyethylene or polypropylene film having a weight of from 10 to 150 g / m 2 , or a metal film, such as an aluminum foil, can be used as the cover layer material. The perforated film may be in the form of a laminate, including a laminate consisting of a plastic film and a paper layer, or a plastic film and a metal film.

Materiál krycej vrstvy môže obsahovať retardér horenia, ktorým môže byť akýkoľvek známy retardér horenia, ako napríklad retardéry horenia obsahujúce halogénové zlúčeniny, fosforové zlúčeniny, alebo látky obsahujúce vodu, alebo látky uvoľňujúce vodu pri vystavení teplu.The liner material may comprise a flame retardant, which may be any known flame retardant, such as flame retardants containing halogen compounds, phosphorus compounds, or water-containing substances or water-releasing substances upon exposure to heat.

Tam, kde je zvlášť vyrobený materiál krycej vrstvy spojený s materiálom z minerálnych vlákien pomocou vrstvy lepidla, môže mať uvedená vrstva lepidla formu plne priliehajúcu, pre vzduch priepustné vrstvy, t.j. vrstvy pokrývajúce v podstate všetky body dotyku medzi krycím materiálom a materiálom z minerálnych vlákien, alebo môže mať formu oddelených zón vo forme pásov, prúžkov, bodiek alebo radov bodiek.Where a separately made coating material is bonded to the mineral fiber material by means of an adhesive layer, said adhesive layer may take the form of a fully adjacent, air permeable layer, i. a layer covering substantially all points of contact between the cover material and the mineral fiber material, or it may take the form of separate zones in the form of strips, strips, dots or dots of rows.

Výhodné je použitie adhezívnych vrstiev vo forme pásov, prúžkov alebo radov bodiek, tiahnucich sa kolmo na smer, v ktorom je materiál najľahšie stlačiteľný. Týmto usporiadaním je možné zabrániť tomu, aby opatrenie krycou vrstvou spôsobilo zmenšenie stlačiteľnosti dosky pri stlačovaní materiálu z minerálnych vlákien, pretože krycí materiál tvorí pravidelné, pozdĺžne záhyby v zónach tvaru pásu medzi pásmi, prúžkami, resp. radmi bodiek lepidla.It is preferred to use adhesive layers in the form of strips, strips or rows of dots extending perpendicular to the direction in which the material is most easily compressible. By this arrangement it is possible to prevent the coating with the coating from decreasing the compressibility of the board when compressing the mineral fiber material, since the covering material forms regular, longitudinal folds in the strip-shaped zones between the strips, strips, respectively. rows of glue dots.

Pri použití tepelne vytvrditeľného spojiva v materiáli z minerálnych vlákien spočíva výhodný spôsob spojovania krycej vrstvy s materiálom z minerálnych vlákien v kontaktovaní častí materiálu krycej vrstvy s povrchom materiálu z minerálnych vlákien pred tepelných vytvrdením spojiva, a následnom tepelnom vytvrdením spojiva.When using a thermosetting binder in a mineral fiber material, the preferred method of bonding the topsheet to the mineral fiber material is to contact portions of the topsheet material with the surface of the mineral fiber material before thermally curing the binder, and then thermally curing the binder.

Pri tomto spôsobe častice spojiva, umiestnené tesne na povrchu vrstvy minerálnych vlákien, tvoria väzby medzi krycou vrstvou a vrstvou minerálnych vlákien a tým ich navzájom spojujú. Tento spôsob poskytuje tú výhodu, že je možné sa vyhnúť použitiu lepidla, čím je znížená tepelná kapacita výslednej dosky a sú zlepšené protipožiarne vlastnosti dosky.In this method, the binder particles placed close to the surface of the mineral fiber layer form bonds between the cover layer and the mineral fiber layer and thereby connect them to each other. This method provides the advantage that the use of glue can be avoided, thereby reducing the heat capacity of the resulting board and improving the fire performance of the board.

Pri použití plne pripojenej krycej vrstvy je uvedená krycia vrstva výhodne vytvorená z materiálu majúceho vysokú flexibilitu, takže krycia vrstva neznižuje v nevhodnej miere stlačiteľnosť dosky.When using a fully bonded cover layer, said cover layer is preferably formed of a material having high flexibility so that the cover layer does not unduly reduce the compressibility of the board.
