Katon kate- ja eristysmateriaalien tukikerroksena kaytet-tava laminaatti
Keksintd koskee katon kate- ja eristysmateriaalien 5 tukikerroksena kaytettavaa laminaattia, joka muodostuu esilujitetusta tekokuitumatosta ja esilujitetusta mineraa-likuitumatosta, jotka on kiinnitetty toisiinsa neulaamal-la. KeksinnOn mukaiselle laminaatille on tunnusomaista, etta mineraalikuitumatossa on pitkittSissuuntaisia, mine-10 raaliaineksesta valmistettuja lujitelankoja.
Kåsiteltåvånå oleva keksintO on parannus FI-patent-tihakemuksen 853 681 mukaisen laminaattiin, joka muodostuu esilujitetusta tekokuitumatosta ja esilujitetusta mineraa-likuitumatosta, jotka on kiinnitetty toisiinsa neulaamal-15 la, ja jota kaytetaan tukikerroksena kattojen kate- ja eristysmateriaalien valmistuksessa.
FI-patenttihakemuksen 853 681 mukaan valmistetuilla laminaateilla ja niista valmistetuilla bitumikatemateriaa-leilla on hyvat termomekaaniset ominaisuudet ja selvdsti 20 parantunut palonkestavyys. vahaiset mittapoikkeamat eli 0,2-0,5 % mahdollistavat jopa bitumikatteen asettamisen jo asetetun katteen våliin.
US-patenttijulkaisussa 4 135 029 kuvataan lasikui-tumattoa, jossa on pitkittaissuuntaisia lujitelankoja.
. 25 Julkaisussa ei mainita mitåån lasikuitumaton esilujittami- sesta tai sen yhdistamisesta tekokuitumattoon. Julkaisuis-ta ei mydskaan ilmene, etta pitkittaissuuntaisilla lujite-kuiduilla saavutettaisiin huomattavasti parantunut stabi-liteetti poikkisuunnassa.
30 US-patenttijulkaisussa 3 975 565 kuvataan yhdistel- maa, joka muodostuu polykiteisesta, korkeita lampdtiloja kestavasta metallioksidista valmistetusta kuitumatosta ja orgaanisista kuiduista valmistetusta, huomattavasti ohuem-masta matosta. Tdma kaksikerroksinen yhdistelma eroaa sel-35 vasti esilia olevan keksinnOn mukaisesta laminaatista sii- •« 2 89189 nå, ettå mineraalikuitumatto ja orgaanisista kuiduista muodostuva matto eivåt ole esilujitettuja, mineraalikuitumatto ei sisållå lujitekuituja ja orgaanisen maton neli6-paino on oleellisesti pienempi kuin epåorgaanisen maton 5 neliOpaino. Mainitulla yhdistelmållå ei pyritå yhdiståmåån epåorgaanisen kuitumaton kuumankeståvyyttå ja orgaanisen maton taivutuslujuutta, vaan yhdistelmån tarkoitus on vain mahdollistaa erittåin hauraista epåorgaanisista kuiduista muodostettujen mattojen lujittaminen mekaanisesti, so. 10 neulaamalla, ilman sideainetta. Julkaisussa todetaan, ettå hauraista epåorgaanisista kuiduista muodostuvien mattojen lujittaminen tunnetulla neulaamismenetelmållå ei onnistu, koska hauraat epåorgaaniset kuidut tållOin katkeavat eikå lujitusta tapahdu. Tåmån vuoksi julkaisussa ehdotetaan 15 mainituista epåorgaanisista kuiduista muodostuvan, suh-teellisen paksun maton peittåmistå erittåin ohuella, orgaanisista synteettikuiduista muodostuvalla matolla ja tåmån yhdistelmån neulaamista, jolloin neulat tydnnetåån orgaanisen maton puolelta yhdistelmåån. Tållå menettelyllå 20 neulat tydntyvåt syvålle sisåån epåorgaaniseen mattoon, jolloin saavutetaan neulaamiselle tyypillinen lujitusvai-kutus.
US-patenttijulkaisussa 4 552 876 kuvataan yhdistel-måå, joka muodostuu epåorgaanisista kuiduista valmistetus- .. 25 ta matosta ja orgaanisista kuiduista valmistetusta matos- • · > ta. Kumpaakaan mattoa ei ole esilujitettu eikå epåorgaani-nen matto sisållå lujitelankoja. Mattoyhdistelmån ainoa lujitus tapahtuu neulaamalla matot toisiinsa, jolloin vaa-ditaan våhintåån 700 pistoa nelidtuumaa kohti riittåvån 30 lujituksen aikaansaamiseksi. Julkaisun mukaan on tårkeåå, ettå epåorgaaniset kuidut pystyvåt vapaasti liikkumaan ja våistymåån niin, etteivåt ne vahingoitu, kun neulat ty6n-tyvåt orgaanisen maton puolelta kerrosrakenteeseen. Tåmå osoittaa, ettei epåorgaanisista kuiduista muodostuva matto 35 saa olla esilujitettu.

Kasitelt&v&na olevan keksinndn tehtavana on, samal-la sailyttaen esim. FI-patenttihakemuksen 853 681 mukaisen laminaatin kaikki edut, parantaa edelleen mittapysyvyytta, erityisesti poikkisuunnassa, siten, etta laminaattien luo-5 tettavuus vaiiin asetettujen katemateriaalien tukikerrok-sena paranee.
Mittapysyvyytta poikkisuunnassa voidaan yliattaen parantaa siten, etta kaytetaan esilujitettua mineraalikui-tumattoa, jossa on pituussuuntaisia mineraalilujitelanko-10 ja.
Erityisen edullisia ovat lasikuitumatot, joissa on lasiluj itelankoj a.
Naiden lujitelankojen yksittais- ja kokonaistitteri sovitetaan kulloisenkin tehtavan mukaan, samoin pitkit-15 taislujitelankojen vaiimatka.
Tavanomaisessa ja suositeltavassa kaytOssa eli kun polymeerimaton neliOpaino on, kuten FI-patenttihakemuk-sessa 853 681 myOs kuvataan, 50-350 g/m2 ja lasikuitumaton 10-100 g/m2, lasilankojen sopiva vaiimatka on 5-25 mm tit-20 terin ollessa 500-2500, edullisesti 1100 dtex. Lasilankojen vaiimatkojen eivat kuitenkaan tarvitse olla ehdottoman tarkkoja.
Filamenttititterin valinnalla ja lujitelankojen vålimatkalla voidaan saataa laminaatin voima-venymasuhdet-.25 ta. TailOin pyritaan siihen, etta voidaan yhdistaa bitumi-katteen muodostuksessa tarkea lasilangan jyrkka alkumoduu-li ja polyesterin taman jaikeisen voima-venymakayran loi-vempi kulku siten, etta voima-venymakayran kulku on mah-dollisimman tasaista.
30 Monet pitkittaissuuntaiset, yhdensuuntaiset lasilu- • jitelangat parantavat odotetusti laminaatin termomekaani- sia ominaisuuksia pituussuunnassa. Yliattavaa oli kuiten-kin, etta mittapysyvyys parani poikkisuunnassa selvasti enemman kuin pituussuunnassa. Poikkisuuntainen mittapysy-35 vyys parani kertoimella 15-30, erityisesti 19-30.

KeksinnOn mukainen laminaatti sopii erittain hyvin kattojen kate- ja eristysmateriaalien tukikerrokseksi ja lisaksi mybs erikoiskatteiden kuten rullapinnoituskattei-den, kylmSssa itseliimautuvien katteiden ja paanujen val-5 mistukseen.
Maaratyissa olosuhteissa (tuulettomuus, voimakas ja pitkaaikainen auringonpaiste) asetetun katteen lampdtila voi kohota 70-80°C:seen.
Mittapoikkeamat 80°C:ssa kuvaavat katteen kayttayty-10 mista lampdtilan vaihdellessa katolla. Ne maaritettiin seuraavasti:
Katepalaan (n. 30 x 30 cm) piirrettiin pituus- ja poikkisuunnassa kaksi 25 cm:n mittaviivaa. Sitten koekap-paleet asetettiin yhdeksi tunniksi lampOkaappiin, jonka 15 lampdtila pidettiin 80°C:ssa (± 1°C). LampOkasittelyn jai- keen vleia pehmea katekoekappale poistettiin lampdkaapista alustana toimivan tiheasilmaisen V2A-teraslankaverkon ke-ra. Koekappale nostettiin hitaasti kahdesta kulmasta sa-manalkalsestl kiinnipitaen ja asetettiin sitten paperirai-20 nalla, esim. kreppipaperille, jottei mahdollinen kutistu-minen jaahtymisen aikana estyisi.
Tunnin jaahtymisajan kuluttua merkkien vaiiset etaisyydet mitattiin ja merkittiin muistiin prosentuaali-set muutokset alkuperaisista etaisyyksista.
25 Tama mittausohje kehitettiin SIA-normin tai UEAtc:n • « katoneristyssysteemeja koskevien ohjeiden pohjalta. Mit-tausohjetta kaytettiin myOs seuraavissa esimerkeissa mitta poikkeamien maarittamiseksi.
Seuraavissa esimerkeissa osoitetaan keksinndn mu-30 kaisen laminaatin edut bitumikatteen tukikerroksena. Kek-: sinndn mukainen laminaatti sopii kuitenkin myds elastomee- reilia tai plastomeereilia muunnettujen bitumipinnoittei-den tukikerrokseksi, eristysmateriaaleihin kadun- ja sil-lanrakennuksessa ja vastaavaan kayttOOn.
