Description

Menetelmä kaksi- tai useampikerroksisen mineraalivillaeristeen valmistamiseksiA method of making a two- or more-layer mineral wool insulation

Esillä olevan keksinnön kohteena on itsenäisen patenttivaatimuksen 1 johdanto-osan 5 mukainen menetelmä kaksi- tai useampikerroksisen mineraalivillaeristeen valmistamiseksi.The present invention relates to a method for producing a two- or more-layer mineral wool insulation according to the preamble of independent claim 1.

Tekniikan tasossa tunnetaan erilaisia menetelmiä useampikerroksisen mineraalivillaa olevan eristeen valmistamiseksi. Julkaisussa W02014090670 esitetään menetelmä, 10 jossa muodostetaan mineraalivillaa oleva pohjakerros, jossa kuidut ovat olennaisesti kohtisuorassa pohjakerroksen pääpintoihin nähden ja joka pohjakerros karkaistaan. Karkaistun pohjakerroksen päälle levitetään karkaisematon mineraalivillakerros, ja yhdistelmä viedään karkaisu-uuniin, jossa pintakerrosta puristetaan vähintään 50 %. Julkaisussa EP1180182 esitetään menetelmä, jossa mineraalivillamatosta leikataan 15 ohut mineraaliviHaviilu vaakasuuntaisella leikkuuterällä, joka leikattu viilu puristetaan rullien välissä tiiviimmäksi ja levitetään takaisin sen mineraalivillamaton, josta viilu leikattiin, loppuosan päälle. Lopuksi jäykän pintakerroksen muodostavaa irtomateriaalia levitetään puristetun mineraalivillakerroksen yläpinnalle ja saatu tuote päällystetään ohuella polyesterikankaalla ja viedään karkaisukäsittelyyn. Tarkoituksena on 20 tuottaa erittäin jäykkä pintakerros, jonka tiheys on vähintään 450 kg/m3.Various methods for producing a multi-layer mineral wool insulation are known in the art. WO2014090670 discloses a method of forming a base layer of mineral wool in which the fibers are substantially perpendicular to the major surfaces of the base layer and each base layer is tempered. An unhardened mineral wool layer is applied over the hardened base layer, and the combination is introduced into a tempering furnace where the surface layer is compressed by at least 50%. EP1180182 discloses a method in which a thin mineral veneer is cut from a mineral wool mat with a horizontal cutting blade, the cut veneer being pressed more tightly between the rolls and spread back over the rest of the mineral wool from which the veneer was cut. Finally, the loose material forming the rigid surface layer is applied to the upper surface of the pressed mineral wool layer, and the obtained product is coated with a thin polyester fabric and subjected to a tempering treatment. The purpose is to produce a very rigid surface layer with a density of at least 450 kg / m 3 .

Esillä olevan keksinnön päämääränä on aikaansaada suhteellisen yksinkertainen ja helposti käyttöön otettava menetelmä useampikerroksisen mineraalivillaeristeen valmistamiseksi hyödyntämällä kierrätysmateriaalia, jota saadaan joko samasta lai25 toksesta, jossa valmistetaan mineraalivillatuotteita tai asiakkailta tulevana ylijäämämateriaalin palautuksena.It is an object of the present invention to provide a relatively simple and easy-to-implement method for producing a multilayer mineral wool insulation utilizing recycled material obtained either from the same plant in which the mineral wool products are produced or as a return of surplus material from customers.

Tämän päämäärän saavuttamiseksi keksinnön mukaiselle menetelmälle on tunnusomaista itsenäisen patenttivaatimuksen 1 tunnusmerkkiosassa esitetyt asiat.To achieve this object, the method according to the invention is characterized by the things set forth in the characterizing part of independent claim 1.

Keksinnön mukaisessa menetelmässä voidaan tarvittaessa vielä puristaa ennen karkaisu-uunia tai karkaisu-uunissa, mineraalivillamaton ja kierrätysmateriaalia käsittävän lisäeristyskerroksen muodostamaa mineraalivillaeristettä, halutun tiheyden (joka voi olla myös lopullinen tiheys) aikaansaamiseksi.In the process according to the invention, if necessary, the mineral wool insulation formed by the additional insulation layer comprising mineral wool and an additional insulating layer comprising recycled material can be further compressed before or in the tempering furnace to obtain the desired density (which can also be the final density).

Kierrätysmateriaalia oleva kerros muodostetaan ainakin yhdeltä ominaisuudeltaan erilaiseksi mineraalivillamattokerrokseen nähden, joka ominaisuus on valittu ryhmästä, johon kuuluu, kuitukemia, kuidun pituus, kuituorientaatio, sideaine, tiheys, kerrospaksuus, puristuslujuus. Menetelmässä kierrätysmateriaalia olevan lisäeristyskerroksen ulkopinnalle lisätään edullisesti lasikuitukangasta oleva päällyskerros ennen mineraalivillaeristeen viemistä karkaisukäsittelyyn. Menetelmässä tuodaan mineraalivillamaton kummallekin pääpinnalle kierrätysmateriaalia sisältävä lisäeristyskerros.The layer of recycled material is formed with at least one property different from the mineral wool mat layer, which property is selected from the group consisting of fiber chemistry, fiber length, fiber orientation, binder, density, layer thickness, compressive strength. In the method, a top layer of fiberglass cloth is preferably added to the outer surface of the additional insulation layer of recycled material before the mineral wool insulation is subjected to the tempering treatment. In the method, an additional layer of recycled material containing recycled material is applied to each major surface of the mineral wool.

Esillä olevan keksinnön etuna on se, että olemassa olevaan mineraalivillamaton valmistuslinjaan ei tarvitse tehdä suuria muutoksia keksinnön mukaisen menetelmän käyttöönottamiseksi. Mineraalivillamatto valmistetaan normaalisti eikä sitä tarvitse käsitellä erityisesti ennen lisäkerroksen syöttämistä mineraalivillamaton ainakin yhdelle pääpinnalle. Lisäkerros syötetään esim, hihnakuljettimien välissä haluttuun tiheyteen puristettuna mineraalivillamaton päälle ja näin saatu eristystuote viedään karkaisukäsittelyyn, esim, karkaisu-uuniin, jossa mineraalivillamatossa ja lisäeristyskerroksessa olevat sideaineet kovettuvat lämmön vaikutuksesta ja kerrokset kiinnittyvät samalla toisiinsa.An advantage of the present invention is that no major changes need to be made to the existing mineral wool production line to implement the method of the invention. The mineral wool mat is manufactured normally and does not need to be treated especially before the additional layer is applied to at least one main surface of the mineral wool mat. The additional layer is fed, e.g., between the belt conveyors, pressed to the desired density on the mineral wool and the insulation product thus obtained is subjected to a tempering treatment, e.g. a tempering furnace, where the binders in the mineral wool mat and the additional insulation layer are heat cured and the layers adhere.

Seuraavassa keksintöä selostetaan lähemmin oheisiin piirustuksiin viitaten, joissa:The invention will now be described in more detail with reference to the accompanying drawings, in which:

Kuvio 1 esittää keksinnön mukaisen menetelmän suorittamiseen soveltuvan laitteiston erästä edullista suoritusmuotoa, jaFigure 1 shows a preferred embodiment of an apparatus suitable for carrying out the method according to the invention, and

Kuvio 2 esittää erään menetelmällä valmistetun mineraalivillaeristeen kaaviollista poikkileikkausta.Figure 2 shows a schematic cross-section of a mineral wool insulation produced by the method.

Mineraalivillaa olevien eristystuotteiden, kuten esim, mineraalivillalevyjen valmistukseen käytettävä maton muodossa oleva raakamineraalivillamatto valmistetaan perustuotantolinjalla muodostamalla ensin mineraaliviIlakoituja kivisulasta, joista sitten mineraalivillaa olevan primäärimaton kautta laskostamalla muodostetaan mineraalivillaa oleva sekundäärimatto. Tämä tapa tuottaa ns. raakavillaa on kuvattu esim, julkaisuissa WO 94/16162, WO 2006/070055 ja WO 03/008353.The raw mineral wool mat in the form of a mat used for the production of mineral wool insulation products, such as mineral wool sheets, is made on a basic production line by first forming mineral waxed stone melt, which is then folded through a primary mineral wool mat to form a secondary mineral wool mat. This method produces the so-called. raw wool is described, for example, in WO 94/16162, WO 2006/070055 and WO 03/008353.

Kuvion 1 mukaisessa laitteistossa valmistuslinjan alkupäässä (ei esitetty) sinänsä tunnetulla tavalla valmistettua raakavillaa olevaa mineraalivillamattoa 2 kuljetetaan hihnakuljettimien 4, 5 välissä haluttuun tiheyteen puristettuna ja edelleen rullien 9 avulla kohti karkaisu-uunia 8. Laitteistoon kuuluu mineraalivillamaton 2 valmistuslinjalle liitetty syöttölaitteisto, johon kuuluu hihnakuljettimet 6, 7 joiden välissä Iisäeristyskerrosta 3 puristetaan (esim, haluttuun tiheyteen) ennen sen syöttämistä mineraalivillamaton 2 yläpinnalle 11. Puristusmäärä voi olla esim. 50 % tai enemmän halutusta tiheydestä riippuen. Maitomainen lisäeristyskerros 3 painetaan ohjausrullan 10 avulla vasten mineraalivillamaton yläpintaa. Laitteistoon kuuluu edullisesti välineet valinnaisen päällystemateriaalin 13 syöttämiseksi rullalta 14 lisäeristyskerroksen ulkopinnalle pitämään lisäeristyskerroksen kuitumateriaalin ja sideaineen paikoillaan lisäeristyskerroksessa karkaisu-uunin ilmavirrassa. Päällystemateriaalina 13 käytetään edullisesti lasikuitukangasta tai -huopaa. Keksinnön mukaisessa menetelmässä mineraalivillamaton 2 kummallekin puolelle lisätään lisäeristyskerros 3, 3'ja samoin kummankin lisäeristyskerroksen ulkopinnalle lisätään edullisesti päällystemateriaali 13.In the apparatus according to Fig. 1, at the beginning of the production line (not shown), a raw wool mat 2 made of raw wool is conveyed between the belt conveyors 4, 5 to the desired density and further by rollers 9 towards a tempering furnace 8. , 7 between which the additional insulation layer 3 is compressed (e.g. to the desired density) before it is fed to the upper surface 11 of the mineral wool mat 2. The compression rate may be e.g. 50% or more depending on the desired density. The additional milky insulating layer 3 is pressed against the upper surface of the mineral wool by means of a guide roller 10. The apparatus preferably includes means for feeding an optional coating material 13 from the roll 14 to the outer surface of the additional insulating layer to hold the additional insulating layer fibrous material and binder in place in the additional insulating layer in the air flow of the tempering furnace. A glass fiber fabric or felt is preferably used as the coating material 13. In the method according to the invention, an additional insulating layer 3, 3 'is added to each side of the mineral wool mat 2, and likewise a coating material 13 is preferably applied to the outer surface of each additional insulating layer.

Kuviossa 2 on esitetty poikkileikkauksena keksinnön mukaisella menetelmällä valmistettu mineraalivillaeriste 1, jossa on mineraalivillamattoa 2 oleva keskikerros ja sen kummallakin puolella olevat, kierrätysmateriaalista muodostetut lisäeristyskerrokset 3, 3'. Kierrätysmateriaalin määrä on edullisesti n. 16 % mineraalivillamaton määrästä. Keksinnön mukaisesti tuotetun mineraalivillaeristeen 1 mineraalivillamatosta muodostuva keskikerros 2 on edullisesti tiheydeltään alueessa 60-80 kg/m3 ja sen paksuus on esim. 100 mm. Kierrätysmateriaalista muodostuvan lisäeristyskerroksen 3, 3' tiheys on edullisesti alueessa 150-250 kg/m3 sen paksuuden ollessa esim, alueessa 10-20 mm.Figure 2 shows a cross-section of a mineral wool insulation 1 made by the method according to the invention, which has a middle layer of mineral wool mat 2 and additional insulation layers 3, 3 'formed on both sides of recycled material. The amount of recycled material is preferably about 16% of the amount of mineral wool. The middle layer 2 of mineral wool mat 1 of the mineral wool insulation produced according to the invention preferably has a density in the range of 60-80 kg / m 3 and its thickness is e.g. 100 mm. The density of the additional insulating layer 3, 3 'made of recycled material is preferably in the range of 150-250 kg / m 3 with a thickness of e.g. 10-20 mm.

Lisäeristyskerroksen materiaalina on pääasiassa revitty/jauhettu/murskattu mineraaIivillamateriaali, johon on lisätty repimisen/jauhatuksen/murskauksen yhteydessä tai sen jälkeen kuivaa pulverimaista sideainetta, joka voi olla erilaista kuin mineraaliviIlamatossa käytetty sideaine. Kierrätysmateriaali voi sisältää myös muita murskattuja/hienonnettuja materiaaleja, kuten betoni-/puujakeita tai palonsuoja- tai muita lisäaineita. Esimerkkejä palonestoaineina toimivista lisäaineista ovat kipsi, sammutettu kalkki, kalsium karbonaatti, kalsiumsulfaattihemihydraatti, dolomiitti, alumiinihydroksidi, alumiinisulfaatti, magnesiumhydroksidi, magnesiumkarbonaatti, montmorilloniitti, bentoniitti. Esimerkkejä palonestoaineina toimivista lisäaineista, jotka paisuvat korkeassa lämpötilassa ovat vermikuliitti, perliitti, hohkakivi, sekä paisutettavia savilajeja.The material of the additional insulation layer is mainly a torn / ground / crushed mineral wool material to which a dry powdery binder has been added during or after tearing / grinding / crushing, which may be different from the binder used in the mineral wool mat. The recycled material may also contain other crushed / chopped materials, such as concrete / wood fractions or fire retardant or other additives. Examples of additives which act as flame retardants are gypsum, slaked lime, calcium carbonate, calcium sulphate hemihydrate, dolomite, aluminum hydroxide, aluminum sulphate, magnesium hydroxide, magnesium carbonate, montmorillonite, bentonite. Examples of additives that act as flame retardants that swell at high temperatures include vermiculite, perlite, pumice, and expandable clays.

Kerrosten paksuutta ja tiheyttä vaihtelemalla niihin saadaan haluttaessa erilaiset ominaisuudet, kuten esim, puristuslujuus.By varying the thickness and density of the layers, various properties are obtained, if desired, such as, for example, compressive strength.
