Description
Denne oppfinnelse angår asbestfritt, varmeherdbart tettingsmateriale egnet for omvikling og tetting av rør som inngår i avgass-systemet tilknyttet en forbrenningsmotor, hvilket materiale herdner til en stiv, sprekk-fri masse og danner en tetting som forblir intakt, idet materialet herdner ved oppvarmning når avgass-systemets rør oppvarmes av de varme avgasser.
En kjent form av varmeherdbare tettingsmaterialer egnet
for ovennevnte formål omfatter adskilte fibre av asbest blandet med en vandig oppløsning av et alkalimetallsilikat (natriumsilikat) slik at det dannes en plastisk pasta med hvilken hull som er dannet ved korrosjon på ledningen/røret, kan tettes til. En annen form omfatter en filt av asbestfibre, hvor filten er impregnert med et vandig alkalimetallsilikat slik at det dannes en bandasje (i England gjerne kalt "silencer repair bandage") som kan vikles rundt, og formes for hånd rundt, ledningen/røret, hvorved hullene tettes. I begge tilfeller er det ønskelig å anvende et fuktbevarende middel i tettingsmaterialet, så som etylenglykol, propylenglykol, glycerol eller lignende organiske polyhydroksyforbindelser, for å redusere hastigheten av vanntapet under lagring av materialet ved omgivelsestemperatur og således holde det plastisk. Materialet herdner ved oppvarmning (så som når det oppvarmes av varme avgasser) og danner en effektiv tetting i flere måneder.
Den foreliggende oppfinnelse tar sikte på å tilveiebringe et asbestfritt tettingsmateriale og er delvis basert på den oppdagelse at andre fibre, selv om de ikke er varmeresistente på samme måte som asbestfibre, er egnet til bruk for forsterkning av varmeherdbare tettingsmaterialer (som således holdes intakt) under varmeherdingen på angjeldende substrat.
Det er allerede blitt foreslått at naturlige cellulosefibre (fortrinnsvis av bastvarianten) bør anvendes, og britisk patent 2055857B beskriver cellulosefibre-innesluttende materialer av denne art.
Skjønt slike materialer er effektive som beskrevet, er det nå blitt funnet at forbedret ytelse kan oppnås.
Materialet ifølge foreliggende oppfinnelse består i hovedsak av en fibrøs forsterkning i form av en kardet eller nålet vev eller filt, et løst-vevet tekstil eller et strikket tekstil inneholdende aramid-fibre og fibre av regenerert cellulose, idet fibrene av regenerert cellulose foreligger i en mengde
under den ved hvilken delaminering eller sprekkdannelse fin-ner sted når materialet utsettes for brukstemperaturene,
hvilken fibrøse forsterkning lett lar seg forme for tetting av det eller de rør som tettingsmaterialet anvendes på, og idet forsterkningen er impregnert med en vandig dispersjon
av
et finpulverisert fyllstoff som gir tettingsmaterialet fyl-dighet og gir det fasthet på nevnte rør,
et varmeherdbart bindemiddel av vanndispergerbart silikat,
og
et fuktbevarende middel i en mengde som reduserer hastigheten av vanntapet fra tettingsmaterialet og plastiserer dette under lagring ved omgivelsestemperaturer før oppvarmning,
resten vann.
Anvendelse av disse spesielle forsterkningsformer er spesielt foretrukket. Ikke bare er ikke-vevede baner og/eller filt med sannsynlighet billigere enn konvensjonelle tekstiler, men alle de foretrukne forsterkninger er mer føyelige enn sistnevnte. De lar seg langt bedre vikle, en vesentlig faktor når det gjelder å oppnå god tettingsytelse på varme substrater.
Fyllstoffet kan være finpulverisert leire, talkum, silisiumdioksyd eller skifer, eller en blanding av to eller flere av disse. Dets funksjon er å gi fylde, spesielt i det herdede materiale i bruk på et substrat.
Da aramidfibre er relativt kostbare, kan banen, filten eller tekstilet innbefatte andre syntetiske organiske fibre; spesielt kan fibre av regenerert cellulose (viskose) anvendes. Det er imidlertid ønskelig at andelen av relativt lavt smeltende og/eller vannholdige fibre holdes under den mengde ved hvilken delaminering/sprekkdannelse blir et problem når materialet utsettes for anvendelsestemperaturene under bruken.
Noen eksperimentering kan selvsagt være nødvendig for å komme frem til en hensiktsmessig fiberblanding for en spesiell anvendelse eller temperatur ved den endelige anvendelse. Den fibrøse forsterkning må imidlertid ha både tilstrekkelig sammenhengningsstyrke og føyelighet for at den skal være effektiv som en forsterkning som vil binde materialet sammen og samtidig tillate at det vikles tett rundt et substrat på hvilket det skal danne en tetting. Bindemidlet er fortrinnsvis et vannoppløselig eller vanndispergerbart silikat, skjønt utvalgte borater eller fosfater også kan anvendes. Natriumsilikat er spesielt foretrukket.
Det følgende eksempel vil ytterligere belyse oppfinnelsen.
EKSEMPEL
En nålet filt omfattende ca. 2/3 (på vektbasis) viskose-rayon-fibre og 1/3 (på vektbasis) aramidfibre (de som er i handelen under varmemerkene "KEVLAR" og "NOMEX" var like effektive) ble impregnert med en vandig dispersjon omfattende ca. 25 vekt% natriumsilikat (på basis av faste stoffer) og 13 vekt% leire, resten vann. En mindre andel av monoetylen-glykol ble anvendt som et fuktbevarende middel for å redusere hastigheten av vanntapet fra den impregnerte filt under lagring.
Produktet var meget føyelig og oppviste meget tilfreds-stillende sammenhengningsstyrke ved omvikling rundt et rør.
Ved oppvarmning til ca. 260°C herdnet materialet til en stiv masse uten sprekkdannelse/avskalling, til tross for at tempera-turen var høyere enn viskosefibrenes forkullingspunkt. Den tørkede kompositt inneholdt ca. 25 % leire, 48 % natriumsilikat, 9 % aramidfibre og 18 % (forkullede) viskosefibre (alt på vektbasis).
