ERISTYSMATERIAALI. MENETELMÄ SEN VALMISTAMISEKSI JA VALMISTUKSESSA KÄYTETTÄVÄ LAMINAATTIINSULATION MATERIAL. METHOD OF MANUFACTURE AND LAMINATE USED IN THE MANUFACTURE

Tekniikan ala 5 Keksintö liittyy eristysmateriaaliin, jossa on mineraali- villakerros ja sen päälle muovin avulla liitetty pintakerros.TECHNICAL FIELD The invention relates to an insulating material having a mineral wool layer and a surface layer connected to it by means of a plastic.

Tekniikan taustaTechnology background

Rakennuksissa käytetään eristykseen paperilla päällystet-10 tyjä mineraalivi11alevyjä. Paperi on liitetty villakerroksen pintaan muovikalvon välityksellä. Paperien päällä voi olla vielä esimerkiksi alumiinikalvo.In buildings, paper-coated mineral wool boards are used for insulation. The paper is attached to the surface of the wool layer through a plastic film. The papers may also have, for example, an aluminum foil.

Paperi muodostaa vesihöyry- ja tuulensulun, vahvistaa ja suojaa levyä sekä tekee levyn käsittelyn miellyttävämmäksi 15 estämällä pölyämistä.The paper forms a water vapor and wind barrier, strengthens and protects the disc, and makes the handling of the disc more comfortable by preventing dusting.

Eristysmateriaali olisi parhaiten mahdollisimman palamatonta .The insulation material would be as non-combustible as possible.

Julkaisussa FI 50393 on kuvattu menetelmää eristysmateriaalin valmistamiseksi siten, että eristysmattoon kiinnitetään 20 kuumasaumauksella muovipinnoitettu kalvo, jonka pinnoitteessa on reikiä ja syvennyksiä. Puolisulassa tilassa muovipinnoitteessa olevat reiät suurenevat ja syvennykset aukeavat rei'-iksi. Reiät ovat kuitenkin niin pieniä, että ne suojaavat levyä roiskevedeltä päästäen veden lävitseen vain kaasumai-25 sessa tilassa.FI 50393 describes a method for producing an insulating material by attaching to the insulating mat a heat-sealed plastic-coated film with holes and recesses in the coating. In the semi-molten space, the holes in the plastic coating enlarge and the recesses open into holes. However, the holes are so small that they protect the plate from splash water, allowing water to pass through only in a gaseous state.

Myös julkaisusta AU 84 31322 tunnetaan eristemateriaali, joka muodostuu mineraalivilla- ja pintakeroksista, jotka on liitetty toisiinsa revitetyn muovikalvon avulla. Myös pintakerros on reititetty.Also known from AU 84 31322 is an insulating material consisting of mineral wool and surface layers joined together by a torn plastic film. The surface layer is also routed.

Keksinnön yleinen kuvausGeneral description of the invention

Nyt on keksitty pintakerroksella päällystetty mineraali-villalevy, jossa pintakerroksen kiinnittämiseen käytettävän muovin määrää on voitu vähentää ja siten lisätä tuotteen pa-35 lamattomuutta. Tähän on päästy käyttämällä muovikalvon sijas ta rei'itettyä muovikerrosta.A mineral wool sheet coated with a surface layer has now been invented, in which the amount of plastic used for fixing the surface layer has been reduced and thus the non-combustibility of the product can be increased. This has been achieved by using a perforated plastic layer instead of a plastic film.

Keksintö ja sen eräitä edullisia sovellutuksia on määri-. telty täsmällisesti patenttivaatimuksissa.The invention and some of its preferred applications are definite. specified in the claims.

Erään suoritusmuodon yksityiskohtainen kuvausDetailed description of an embodiment

Kuvauksen piirustuksissa kuvio 1 esittää erästä keksinnönmukaista eristysmateriaalia poikkileikkauksena ja 5 - kuvio 2 siinä käytettävää muovikerrosta paperin pin nalla.In the drawings of the description, Fig. 1 shows an insulating material according to the invention in cross-section and Fig. 5 shows a plastic layer on a paper surface used therein.

Eristysmateriaalissa on mineraalivillaa oleva huokoinen eristekerros 1, sekä sen toiselle puolelle kiinnitetty pape-rikerros 2. Paperikerroksessa 2 on pinnalla vielä haluttaessa 10 pinnoite 3, esimerkiksi alumiinikalvo.The insulating material has a porous insulating layer 1 of mineral wool and a paper layer 2 attached to one side thereof. The paper layer 2 still has a coating 3 on the surface, if desired, for example an aluminum foil.

Paperikerros 2 on kiinnitetty eristekerrokseen reititetyn muovikerroksen 4 avulla.The paper layer 2 is attached to the insulating layer by means of a routed plastic layer 4.

Materiaali valmistetaan parhaiten siten, että ensin paperikerros 2 ja muovikerros 4 liitetään yhteen ja ajetaan ne 15 sitten eristekerroksen 1 päälle muovikerros vasten eristeker-rosta ja kuumennetaan niin että muovi sulaa ja kiinnittää kerrokset yhteen.The material is best made by first joining the paper layer 2 and the plastic layer 4 and then driving them 15 onto the insulating layer 1 against the plastic layer from the insulating layer and heating so that the plastic melts and fixes the layers together.

Muovikerros 4 muodostetaan parhaiten siten, että muoviraaka-aineen seassa käytetään sopivaa lisäainetta, joka ekstruu-20 derilla kuumennettaessa kaasuuntuu. Muovikerros 4 ajetaan ekstruuderilla paperin 2 toiselle pinnalle, ja kaasuuntuva lisäaine muodostaa muovikerrokseen reikiä.The plastic layer 4 is best formed by using a suitable additive among the plastic raw material, which gasifies when heated with an extruder. The plastic layer 4 is driven by an extruder to the other surface of the paper 2, and the gaseous additive forms holes in the plastic layer.

Lisäaineena käytetään erityisesti sopivaa suolaa, joka kuumennettaessa vapauttaa kidevettä höyrynä. Tällaisia ns. 25 master batcheja on kaupallisesti saatavana.A particularly suitable salt is used as an additive, which, when heated, releases water of crystallization as steam. Such so-called 25 master bats are commercially available.

Kuvio 3 esittää kuvatulla tavalla valmistettua reiällistä muovikerrosta 4 paperilla 2 (koko n. 75 % todellisesta). Muovikerroksen 4 pinta-alasta n. 60 - 90 % on reikää. Kerros 4 muodostuu epäsäännöllisesti verkkoutuneista ajosuuntaisista 30 säikeistä.Figure 3 shows a perforated plastic layer 4 made as described on paper 2 (size approx. 75% of the actual). About 60-90% of the surface area of the plastic layer 4 is a hole. Layer 4 consists of irregularly cross-linked strands 30 in the direction of travel.

Kun reititetty muovikerros 4 on polyeteeniä, on riittävä muovimäärä noin 5-10 g/m2, parhaiten n. 7 g/m2. Tämä on huomattavasti vähemmän kuin tunnetuissa vastaavissa eristysmateriaaleissa .When the routed plastic layer 4 is polyethylene, a sufficient amount of plastic is about 5-10 g / m 2, preferably about 7 g / m 2. This is considerably less than in known similar insulation materials.

35 Keksinnön mukaisessa materiaalissa muovikerros muodostuu paksuhkoista (esim. n. 20 - 40 μιη) säikeistä, jotka sulatettaessa myös tarttuvat huokoiseen eristekerrokseen paremmin kuin sileä, ohuempi kalvo. Näin säikeet pysyvät palotilan- 3 95012 teessä pitempään kiinni eristekerroksessa, ja palon etenemi-nenkin on hitaampaa.In the material according to the invention, the plastic layer consists of thick fibers (e.g. about 20 to 40 μιη) which, when melted, also adhere to the porous insulating layer better than a smooth, thinner film. In this way, the strands remain longer in the insulation layer in the fire chamber for 3,95012, and the propagation of the fire is also slower.

Paperin 2 ja pinnoitteen 3 sijasta voi materiaalissa olla pintakerroksena myös pelkkä paperi, pelkkä alumiinikalvo tai 5 jokin muu käyttötarkoituksen kannalta sopiva ratamainen materiaali.Instead of the paper 2 and the coating 3, the material may also contain only paper, a simple aluminum foil or some other web-like material suitable for the intended use.
