Description

Uorganisk råpapp, beregnet for fremstilling av takpapp. Inorganic raw board, intended for the production of roofing board.

Nærværende oppfinnelse vedrbrer en råpapp for takpapp, bestående av uorganiske fibre samt bindemiddel, og som er karakterisert ved at råpappen er tilsatt findelt, vulkanisert gummi, eller annet hdypolymert materiale med tilsvarende egenskaper. The present invention relates to a raw cardboard for roofing felt, consisting of inorganic fibers and a binder, and which is characterized in that the raw cardboard has added finely divided vulcanized rubber or other high-polymer material with similar properties.

Takpapp basert på ullpapp eller cellulosepapp vil ved skiftende klimatiske forhold delvis ta opp: fuktighet eller avgi fuktighet. Det variable fuktighetsinnhold vil fore til at pappen "arbeider", og det kan oppstå blæredannelse på grunn av damplommer. Dess-uten vil organiske fibre ha en tilbøyelighet til å råtne. Roofing board based on wool board or cellulose board will, in changing climatic conditions, partially absorb: moisture or give off moisture. The variable moisture content will cause the cardboard to "work", and blistering may occur due to steam pockets. Otherwise, organic fibers will have a tendency to rot.

Det er derfor onskelig å anvende råpapp av uorganiske fibre, og det er tidligere utviklet slike basert på for eksempel diverse kvaliteter av glassfibre. De fleste tilgjengelige kvaliteter oppviser vekter fra 50 - 70 g/m . Disse produkter (også kalt glass-"vliess") har: funnet stor,anvendelse som stamme for under-lagspapp. For overlagspapp har disse tynne glass-"vliess"-kvaliteter ikke funnet særlig stor anvendelse. En vesentlig inn-vending mot å anvende disse produkter i overlagspapp er råpappens lille tykkelse som utgjor kun ca. 0,4 mm, mens en topplags ullpapp utgjor ca. 1,4 mm.. Hvis det oppstår oksydasjonssprekker eller andre skader i belegget, vil en lakkasje kunne oppstå i disse tynne glassfiberpappene, mens ullpappen fremdeles har en impregnert papptykkelse på ca. 1,4 mm. Råpappens tykkelse har også betydning for de brann-beskyttende egenskaper. It is therefore desirable to use raw cardboard made of inorganic fibres, and such have previously been developed based on, for example, various qualities of glass fibres. Most available qualities have weights from 50 - 70 g/m. These products (also called glass "vliess") have: found great use as a base for sub-layer cardboard. For laminated board, these thin glass "vliess" qualities have not found much use. A significant objection to using these products in laminated cardboard is the small thickness of the raw cardboard, which only amounts to approx. 0.4 mm, while a top layer of wool cardboard makes up approx. 1.4 mm.. If oxidation cracks or other damage occurs in the coating, a lacquer coating may occur in these thin glass fiber boards, while the wool board still has an impregnated board thickness of approx. 1.4 mm. The thickness of the raw cardboard is also important for the fire-protective properties.

Hvis man prover å lage en tykkere glass-"vliess" (over 70 g/m 2) If you try to make a thicker glass "vliess" (over 70 g/m 2 )

av kontinuerlig dragne glassfibre som etterpå blir kuttet opp eller av mer hbyverdige glass-stapelfibre, vil prisen på produktet fort bli for hoy. For å holde omkostningene på et rimelig nivå, kan man blande inn andre billige uorganiske fibre (som glassull, steinull, dårligere asbestfiberkvaliteter o.l.). of continuously drawn glass fibers which are then cut up or of more valuable glass staple fibres, the price of the product will quickly become too high. To keep the costs at a reasonable level, you can mix in other cheap inorganic fibers (such as glass wool, stone wool, inferior asbestos fiber qualities, etc.).

Disse billige fibre er relativt svake og spro, og en tykk glass-"vliess" med tilsetning av disse fibre vil lett bli stiv og spro. For å få storre fleksibilitet, kan man anvende spesielle fleksible lim, men produktet vil da samtidig tape vesentlig i mekanisk strekkfasthet. These cheap fibers are relatively weak and brittle, and a thick glass "vliess" with the addition of these fibers will easily become stiff and brittle. To obtain greater flexibility, special flexible adhesives can be used, but the product will then lose significantly in mechanical tensile strength.

Formålet med oppfinnelsen er således å tilveiebringe en uorganisk råpapp av en tilstrekkelig stor tykkelse til en rimelig pris, samtidig som man bibeholder en tilstrekkelig fleksibilitet og en tilstrekkelig styrke. Dette oppnås ifolge den foreliggende oppfinnelse ved at man til en blanding av uorganiske fibre og bindemiddel tilsetter f.eks. 0,5 - 50 vektsprosent findelt, vulkanisert gummi under selve fremstillingen av f.eks. den tykke glassfilt. Gummipulveret fremstilles f.eks. ved å The purpose of the invention is thus to provide an inorganic raw cardboard of a sufficiently large thickness at a reasonable price, while maintaining sufficient flexibility and sufficient strength. This is achieved according to the present invention by adding e.g. to a mixture of inorganic fibers and binder. 0.5 - 50% by weight finely divided, vulcanized rubber during the actual production of e.g. the thick glass felt. The rubber powder is produced e.g. by

rive opp gamle bildekkbaner, og man kan eksempelvis anvende gummipulver finere enn 40 mesh. Slikt gummipulver er kjent brukt bl.a. som tilsetning til asfaltblandinger for å bedre de termiske egenskaper. Revne bildekkbaner vil bestå av en blanding av de gummityper som brukes i bildekkbaner, dvs. både tear up old car tire tracks, and you can, for example, use rubber powder finer than 40 mesh. Such rubber powder is known to be used i.a. as an addition to asphalt mixtures to improve the thermal properties. Cracked car tire tracks will consist of a mixture of the rubber types used in car tire tracks, i.e. both

naturgummi og syntetiske gummityper. Uttrykket "gummi" an- natural rubber and synthetic rubber types. The term "rubber" an-

vendt i denne sak dekker således begge disse gunmislag. Blan-dingen av uorganiske fibre og gummipulver blir limt sammen under produksjonen på vanlig måte og ved hjelp av en hensikts-messig limtype. Av vanlige limtyper for slik produksjon kan nevnes urea-formaldehyd, polyakrylsyre-ester, polyvinylalkohol av hby hydrolysegrad og andre kjente limtyper og blandinger av disse. ""Vliessen" kan også fremstilles på forskjellig måte. turned in this case thus covers both of these gunmislaws. The mixture of inorganic fibers and rubber powder is glued together during production in the usual way and with the help of an appropriate type of glue. Of the usual types of glue for such production, mention can be made of urea-formaldehyde, polyacrylic acid ester, polyvinyl alcohol of high hydrolysis degree and other known types of glue and mixtures thereof. "The fleece" can also be produced in different ways.

Det kanskje mest almindelige er å forme "vliessen" forst enten etter en aerodynamisk torr metode eller etter en våt metode i en hydroformer. Etter at "vliessen" er formet, kan limstoffet som forefinnes som vanndispersjon eller vannlosning påfores "vliessen" f.eks. ved en dyppemetode eller ved en påsproytnings-metode. Etterpå blir limstoffet torket og eventuelt herdet. Limstoffet kan også påfores fibrene for "vliessen" dannes, Perhaps the most common is to shape the "fleece" first either by an aerodynamic dry method or by a wet method in a hydroformer. After the "fleece" has been shaped, the adhesive, which exists as a water dispersion or water release, can be applied to the "fleece", e.g. by a dipping method or by a spraying method. The adhesive is then dried and possibly hardened. The adhesive can also be applied to the fibers to form the "fleece",

enten ved en såkalt "beater deposition"-metode eller ved at limlosning og fibre blandes for "vliessen" dannes i hydroformeren. either by a so-called "beater deposition" method or by mixing adhesive release and fibers so that the "nonwoven" is formed in the hydroformer.

Gummipulveret i "vliessen" danner fleksible "broer" eller "stot-puter" som gjor glassfilten mer fleksibel til tross for hoy vekt og stort innhold av spro fibre og uten at bruddstyrken reduseres vesentlig. En slik papp vil få en tykkelse på ca. 1 mm eller mer, og oksydasjonssprekker og andre skader vil derfor ikke medfore stor risiko for lekkasje. En slik råpapp kan således anvendes som basis for topplagspapp. The rubber powder in the "vliessen" forms flexible "bridges" or "stot-pads" which make the glass felt more flexible despite its high weight and high content of spro fibers and without the breaking strength being significantly reduced. Such cardboard will have a thickness of approx. 1 mm or more, and oxidation cracks and other damage will therefore not entail a great risk of leakage. Such raw cardboard can thus be used as a basis for top layer cardboard.

En ytterligere fordel som oppnås er at gummipulveret er med på A further advantage that is achieved is that the rubber powder is included

å gi glassfilten storre bulk (storre porositet). Gummipulveret er også med på å holde asfalten på plass i pappen. (Armere asfalten) . to give the glass felt greater bulk (greater porosity). The rubber powder also helps to keep the asphalt in place in the cardboard. (Reinforce the asphalt) .

EKSEMPEL EXAMPLE

Råpapp med vekt 150 g/m 2 fremstilles .'med folgende sammensetning: 50 g/m 2 tekstilglassfiber kuttet i 6 mm lengder (chopped strand), Raw cardboard with a weight of 150 g/m 2 is produced with the following composition: 50 g/m 2 textile glass fiber cut into 6 mm lengths (chopped strand),

50 g/m 2 glassull (isolasjonsull), 32 g/m 2 gummipulver finere enn 40 mesh fremstilt ved riving av bildekkbaner og 18 g/m<2 >polyvinylalkohollim av hoy hydrolysegrad. Tykkelsen blir ca. 1 mm. Produktet har tilstrekkelig styrke og fleksibilitet samtidig som det har en gunstig pris. Noe forenklet kan man si at tekstilglassfibrene sammen med limet gir produktet den nødven-dige styrke, mens glassullen og gummipulveret er med på å gi produktet den onskede tykkelse og den onskede armering av asfalt, og gummipulveret har avgjbrende betydning for at produktet får den rette fleksibilitet. Produktet er fremstilt på den måte at fibermateriale og gummipulver i riktig forhold er slemmet opp i en stor pulp av ca. 5%-ig polyviny1alkohol-losning (polyvinylalkohol av hoy hydrolysegrad). Etter opp-slemming er det hele kjbrt ut på en hydroformer ("inclined wire hydroformer") og den onskede filt er dannet. Overskudd av limstoff blir filtrert vekk og filten er deretter tbrket og limstoffet i filten til slutt herdet. 50 g/m 2 glass wool (insulation wool), 32 g/m 2 rubber powder finer than 40 mesh produced by tearing up car tire tracks and 18 g/m<2 >polyvinyl alcohol glue of a high degree of hydrolysis. The thickness will be approx. 1 mm. The product has sufficient strength and flexibility at the same time as it has a favorable price. Somewhat simplistically, you can say that the textile glass fibers together with the glue give the product the necessary strength, while the glass wool and the rubber powder help to give the product the desired thickness and the desired reinforcement of asphalt, and the rubber powder is crucial for the product to have the right flexibility. The product is produced in such a way that fiber material and rubber powder are mixed in the right ratio into a large pulp of approx. 5% polyvinyl alcohol solution (polyvinyl alcohol of a high degree of hydrolysis). After slurrying, the whole is fed onto an inclined wire hydroformer and the desired felt is formed. Excess adhesive is filtered away and the felt is then dried and the adhesive in the felt is finally hardened.
