Description

Opfindelsen angår et ark- eller baneformet, bituminøst belægningsmateriale og navnlig tagpap til fuldklæbning på et underlag, hvilket materiale på mindst den ene side er forsynet med et lag var-meaktiverbart bindemiddel, der er dækket af en polyethylenfolie.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a sheet or web-shaped, bituminous coating material, and in particular, to full-adhesive roofing board, which material is provided on at least one side with a layer of heat-activatable binder covered by a polyethylene film.
5 Det er kendt at forsyne tagpap med en talkumafstrøning for at forhindre, at der under oplagring af tagpaprulier sker en sammenklæbning af hosliggende asfaltholdige lag.5 It is known to provide roofing board with a talcum sponge to prevent the adhesion of adjacent asphalt-containing layers during the storage of roofing sheets.
En anden kendt teknik består i at påføre tagpapmaterialet en polyethylenfolie med en tykkelse på ca. 40 μ til beskyttelse mod 10 den nævnte sammenklæbning. Polyethylenfolien udgør et effektivt skillemiddel, idet det er dårligt foreneligt med asfalt. Dette indebærer på den anden side den ulempe, at folien skal fjernes inden påklæbningen af tagpapmaterialet til underlaget, idet foliens tilstedeværelse modvirker en effektiv piklæbning.Another known technique consists in applying a roofing material to a polyethylene foil having a thickness of approx. 40 μ for protection against the said adhesive. The polyethylene foil is an effective separator as it is poorly compatible with asphalt. This, on the other hand, involves the disadvantage that the foil must be removed prior to the adhesive of the roofing material to the substrate, the presence of the foil counteracting an efficient picking.
15 Det er blevet forsøgt at afbrænde polyethylenfolien i forbindelse med opvarmningen af asfalten i tagpapmaterialet umiddelbart før påklæbningen af tagpapmaterialet. Disse forsøg har imidlertid ikke givet noget tilfredsstillende resultat, idet det har vist sig, at folien trækker sig sammen til dannelse af en netlignende struktur, 20 hvilket udelukker en fuidklæbning og derved muliggør indtrængning af fugtighed under tagpapmaterialet.Attempts have been made to burn the polyethylene foil in connection with the heating of the asphalt in the roofing material immediately before the roofing material is adhered. However, these tests have not yielded a satisfactory result, as it has been found that the foil contracts to form a net-like structure, which excludes a fluid adhesion and thereby permits moisture to penetrate under the roofing board material.
Formålet med opfindelsen er at tilvejebringe et bituminøst belægningsmateriale, som er beskyttet mod sammen klæbning, når det foreligger i form af ruller eller stabler, og hvor man uden at foreta-25 ge en afrivning af polyethylenfolien kan fuldklæbe belægningsmaterialet til et underlag.The object of the invention is to provide a bituminous coating material which is protected against adhesion when in the form of rolls or stacks, and in which, without tearing off the polyethylene foil, the coating material can be fully adhered to a substrate.
Dette formål opnås med belægningsmaterialet ifølge opfindelsen, som er ejendommelig ved, at polyethylenfolien har en gennemsnitlig tykkelse pi op til 8 μ.This object is achieved with the coating material according to the invention, which is characterized in that the polyethylene film has an average thickness p up to 8 µ.
30 Ved pålægning af et belægningsmateriale ifølge opfindelsen viser det sig overraskende, at der ved opvarmning af det varmeakti-verbare bindemiddel samtidig indtræder en fuldstændig nedbrydning af den tynde polyethylenfolie, således at der ved den efterfølgende påklæbning af belægningsmaterialet fremkommer en ubrudt forbindelse 35 mellem belægningsmaterialet og underlaget. Dette indebærer, at den afrivning af polyethylenfolien, som man hidtil har været nødsaget til at foretage, helt kan elimineres. Dette betyder ikke alene en væsentlig arbejdsbesparelse men resulterer også i en væsentligt bedre påklæbning, af belægningsmaterialet. Således kunne der ved afrivnin- 2 148285 gen af polyethylenfolien fra det kendte belægningsmateriale let ske det, at dele af folien blev tilbage på belægningsmaterialet og derved resulterede i en dårlig forbindelse mellem belægningsmaterialet og underlaget inden for de områder, hvor der var polyethylenfolie 5 tilbage på belægningsmaterialet.When applying a coating material according to the invention, it is surprisingly found that upon heating the heat-activatable binder, a complete degradation of the thin polyethylene foil occurs simultaneously, so that upon subsequent coating of the coating material, an unbroken connection between the coating material and the coating material is obtained. substrate. This means that the tearing of the polyethylene foil that has hitherto been made to make can be completely eliminated. This not only means a significant work saving, but also results in a significantly better adhesion of the coating material. Thus, upon tearing off the polyethylene film from the known coating material, parts of the film could easily be left on the coating material, thereby resulting in a poor connection between the coating material and the substrate within the areas where polyethylene film 5 was left on. the coating material.
En yderligere fordel ved belægningsmaterialet ifølge opfindelsen er, at man ved nedbrydning af polyethylenfolien undgår, at de afrevne polyethylenfolier, som let blæser bort med vinden, forurener naturen.A further advantage of the coating material according to the invention is that, when decomposing the polyethylene foil, it is avoided that the torn polyethylene foils, which are easily blown away by the wind, contaminate nature.
10 Polyethylenfolien, som indgår i belægningsmaterialet ifølge opfindelsen, har som nævnt en tykkelse på op til ca. 8 μ. Det er særligt hensigtsmæssigt at anvende folier med en tykkelse på ca. 8 μ, idet sådanne folier , har en tilstrækkelig styrke til, at de kan anvendes i de almindeligt anvendte maskiner til fremstilling af belæg-15 ningsmaterialer, såsom tagpap, og samtidig holdes det vægtmæssige forbrug af folie på et acceptabelt niveau.The polyethylene foil contained in the coating material according to the invention has, as mentioned, a thickness of up to approx. 8 µ. It is particularly appropriate to use foils having a thickness of approx. 8 µ, such films, have a sufficient strength to be used in the commonly used machines for the manufacture of coating materials, such as roofing board, and at the same time the weight consumption of film is kept at an acceptable level.
Polyethylenfolien pålægges hensigtsmæssigt det bituminøse belægningsmateriale under fremstillingen af dette, hvilket vil sige på et tidspunkt, hvor det bituminøse belægningsmateriale er opvarmet 20 og har en sådan klæbeevne, at polyethylenfolien bindes til selve belægningsmaterialet.The polyethylene foil is suitably applied to the bituminous coating material during its manufacture, that is, at a time when the bituminous coating material is heated and has such adhesive capacity that the polyethylene foil is bonded to the coating material itself.
Der kan om ønsket være påført en polyethylenfolie med den nævnte tykkelse på begge sider af det bituminøse belægningsmateriale.If desired, a polyethylene film of said thickness may be applied to both sides of the bituminous coating material.
25 EKSEMPELEXAMPLE
Der fremstilles en vandisoleringsmembran på følgende i og for sig kendte måde: Et glasvæv med vægt 120 g/m imprægneres ved neddypning i varm, destilleret bitumen, type 80/100. Derefter påføres på begge sider et 1,5 mm tykt lag af varm, oxideret bitumen, 30 type 85/40 indeholdende 30% talkum som fyldstof, hvorefter begge sider afstrøs med fint talkum. Efter afkøling pålægges på banens bagside et 1 mm tykt lag af ren, oxideret bitumen, type 85/40, og efter afkøling til 100-80°C pålægges en polyethylenfolie med tykkelse 8 μ ved hjælp af en valse. Den således påførte polyethylenfolie yder 35 tilstrækkelig beskyttelse til at hindre, at arkene i en stabel af sådanne membranark klæber sammen. Ved påklæbning af arkene på et underlag, hvorunder der foretages en opvarmning af bitumenlaget med en gasflamme, forsvinder polyethylenfolien helt, hvorved der opnås en fuldklæbning.A water-insulating membrane is prepared in the following manner known per se: A glass fabric weighing 120 g / m is impregnated by immersion in hot, distilled bitumen, type 80/100. Then, on both sides, a 1.5 mm thick layer of warm, oxidized bitumen, type 85/40 containing 30% talc as filler is applied, after which both sides are sprinkled with fine talc. After cooling, a 1 mm thick layer of pure, oxidized bitumen, type 85/40, is applied to the back of the web and, after cooling to 100-80 ° C, a polyethylene film of thickness 8 µ is applied by means of a roller. The polyethylene film thus applied provides sufficient protection to prevent the sheets of a stack of such membrane sheets from sticking together. When adhering the sheets to a substrate during which the bitumen layer is heated with a gas flame, the polyethylene foil completely disappears, thereby obtaining a full adhesive.
