Description
Fremgangsmåte til fastgjøring av Procedure for fixing the
fiberflor og -matter som overveiende predominantly fiber piles and mats
består av .uorganisk materiale. consists of .inorganic material.
Til fremstilling av fiberstrukturer, fortrinnsvis glassfiberflor, som overveiende består av uorganisk material, fremstilles ofte etter dysetrekke-, dyseblåse- og stavtrekkefrem-gangsmåten i første rekke en glassfiber, som hovedsakelig videre-forarbeides. etter følgende tre.i og for seg kjente fremgangsmåter: a) .'Det spundne glass kuttes til fiberbunter av 0,3-10 cm lengde og blåses ved hjelp av en luftstrøm på en vire. , Deretter påsprøytes bindemiddel, og den på denne måte dannede glassfiber- iriatte.tørkes ved oppvarmning.. For the production of fiber structures, preferably glass fiber pile, which predominantly consists of inorganic material, a glass fiber, which is mainly further processed, is often produced by the nozzle drawing, nozzle blowing and rod drawing methods. according to the following three methods known per se: a) The spun glass is cut into fiber bundles of 0.3-10 cm length and blown using an air stream onto a wire. , Binder is then sprayed on, and the fiberglass formed in this way iriatte. is dried by heating..
b) Det smeltede glass trekkes ut til glasstråder. Disse blåses ved hjelp av en luftstrøm på et transportbånd, og det dan- b) The molten glass is drawn out into glass threads. These are blown using an air stream on a conveyor belt, and the

tørket under oppvarmning. Denne fremgangsmåte benevnes tørkeform-eringsfremgangsmåten. c) Etter den såkalte våtformeringsfremgangsmåten påføres glassfiber i form av en vandig.suspensjon, som allerede-.kan innehol-de bindemidlet på en transportvire, idet de hertil anvendte maskiner kan være lik en papirmaskin. dried under heating. This method is called the dry forming method. c) After the so-called wet forming method, glass fiber is applied in the form of an aqueous suspension, which may already contain the binder on a transport wire, as the machines used for this can be similar to a paper machine.
Anvendes som bindemiddel til fastgjøring av glassfiber-florene polyvinylalkohol alene, utmerker de på denne måte fremstilte flor seg riktignok ved fremragende rivfasthet ved normal temperatur, idet rivfastheten går sterkt tilbake ved høyere temperaturer. If polyvinyl alcohol alone is used as a binding agent for fixing glass fiber fleeces, the fleeces produced in this way are certainly distinguished by excellent tear resistance at normal temperatures, as the tear resistance declines strongly at higher temperatures.
Slike flor er derfor uegnet for anvendelsesområder som krever en viss termisk stabilitet, f.eks. for fremstilling av tak-belegg, hvor floret må impregneres med bitumen ved ca. 180-200°C. Dessuten har utelukkende med polyvinylalkohol fastgjorte flor en dårlig vannfasthet, allerede ved 10 minutters kokning i vann ned-brytes floret fullstendig tilsvarende et 100%-ig bindemiddeltap. Dessuten svinger florenes rivfasthet meget sterkt alt etter typen av den anvendte polyvinylalkohol. Such flors are therefore unsuitable for areas of application that require a certain thermal stability, e.g. for the production of roof coverings, where the floor must be impregnated with bitumen at approx. 180-200°C. Furthermore, fleeces attached exclusively with polyvinyl alcohol have a poor water resistance, already after 10 minutes of boiling in water, the fleece breaks down completely corresponding to a 100% loss of binder. In addition, the tear resistance of the fleece varies greatly depending on the type of polyvinyl alcohol used.
Fra belgisk patent nr. 715-130 er det kjent anvendelsen av kombinasjoner av polyvinylalkohol med et overskudd av i vann uoppløselig urinstoff-formaldehyd-forkondensat til binding av glassfiberflor med lav flatevekt. Således fremstilte flor har riktignok likeledes en utmerket riv- og bøyefasthet, deres varmestabilitet er imidlertid stadig utilfredsstillende. From Belgian patent no. 715-130 it is known the use of combinations of polyvinyl alcohol with an excess of water-insoluble urea-formaldehyde pre-condensate for bonding glass fiber pile with a low basis weight. Floss produced in this way also have excellent tear and bending resistance, but their thermal stability is still unsatisfactory.
Oppfinnelsens gjenstand er en fremgangsmåte til fast-gjøring av uorganisk materialholdige fiberstrukturer, fortrinnsvis glassfiberflor og -matter under anvendelse av et bindemiddel og et-terfølgende varmetørkning, idet fremgangsmåten er karakterisert ved at man som bindemiddel anvender en kombinasjon av The object of the invention is a method for fixing fiber structures containing inorganic material, preferably glass fiber piles and mats using a binding agent and subsequent heat drying, the method being characterized by using as binding agent a combination of
a) en høymolekylær polyvinylalkohol, a) a high molecular weight polyvinyl alcohol,
b) en varmeherdbar aldehydharpiks, og b) a thermosetting aldehyde resin, and
c) en syrekomponent. c) an acid component.
Uorganiske materialer, som kan fastgjøres ifølge oppfinnelsen, er spesielt glassfibre, dessuten mineralfibre (asbestr-j slagg-, sten-, og basaltfibre); De kan hvis ønsket være blandet med organiske fibre på basis av polyetylen, polypropylen, polyacrylnitril, polyvinylklorid, polykarbonat, polyuretan, polyester og polyvinylal-. kohol og lignende. Inorganic materials, which can be fixed according to the invention, are especially glass fibres, also mineral fibers (asbestos, slag, stone and basalt fibres); If desired, they can be mixed with organic fibers based on polyethylene, polypropylene, polyacrylonitrile, polyvinyl chloride, polycarbonate, polyurethane, polyester and polyvinyl alcohol. cohol and the like.
