Abstract

Sealing sheets for building applications, esp. roof sealing webs, comprise (a) an outer layer of thermoplastic olefin (TPO), and (b) a lower layer of thermoplastic elastomer (TPE) which is opt. reinforced e.g. with a glass net. Layer (b) serves as an adhesive bridge and has a compsn. of (c) 10-90 phr. SEBS, (d) 5/70 phr. SBS(SIS)SIS and (e) 3-20 phr. uncrosslinked EPDM. The TPE layer may also contain 10-90 phr. aromatic hydrocarbon resin, 20-180 phr. aliphatic hydrocarbon resin, 20-500 phr. bitumen, 20-500 phr. inorganic filler, up to 50 phr. aliphatic plasticiser, up to 10 phr. paraffinic plasticiser and upto 20 phr. carbon black + processing aids. Pref. the TPO layer is 0.1-1 mm. thick and the lower TPE layer is 0.1-5 mm. thick. USE/ADVANTAGE - The lower TPE layer has improved adhesion both to bituminous and to other materials in the region of joins. The materials also exhibit good ageing properties and heat resistance, with a usage temp. range of (-)50 to (+)120 deg.C.

Description

Bauwerksabdichtungen aus thermoplastischen Olefinen (TPO) sind bekannt. Diese Legierung, die als Weichsegment aus vernetztem EP(D)M und als Hartsegment aus PP bzw. PP/PE besteht, besitzt eine gute Alterungsbeständigkeit. Die Dauergebrauchstemperatur beträgt -50°C bis +120°C. Das Schließen der Naht erfolgt problem­ los mit Heißgas. Der große Nachteil jedoch liegt in der stark eingeengten Verlegemethode. Das bedeutet, daß diese Bahnen nur lose unter Auflast oder mechanischer Befestigung zu verlegen sind. Die herkömmlichen Verlegemethoden (z. B. Verkleben in Heißbitumen, Einsatz von Kaltklebern) sind aufgrund der schlechten Klebeeigen­ schaften nicht möglich. Außerdem bestehen erhebliche Schwierig­ keiten, die Dichtungsbahnen im Anschlußbereich und an Durchbrüchen durch Verkleben anzubinden.Building seals made of thermoplastic olefins (TPO) known. This alloy, which is made of cross-linked as a soft segment EP (D) M and consists of PP or PP / PE as a hard segment good resistance to aging. The continuous use temperature is -50 ° C to + 120 ° C. The seam is closed problem off with hot gas. The big disadvantage, however, lies in the strong restricted installation method. That means these tracks only are to be laid loose under load or mechanical fastening. The conventional laying methods (e.g. gluing in hot bitumen, Use of cold glue) are due to the poor adhesive properties not possible. There are also considerable difficulties the sealing sheets in the connection area and at openings tied by gluing.

Überraschenderweise wurde nun gefunden, daß die Bahnen aus TPO nicht nur zum bituminösen Untergrund, sondern auch im Anschluß­ bereich zu anderen Materialien zur Haftung gebracht werden können, wenn die Haftbrücke eine Zusammensetzung gemäß Kennzeichen des Anspruchs 1 aufweist.Surprisingly, it has now been found that the webs are made of TPO not only to the bituminous surface, but also afterwards can be held liable for other materials, if the adhesive bridge has a composition according to the characteristics of the Claim 1 has.

Die Erfindung wird nun anhand einer schematischen Skizze kurz erläutert. Dabei weist die Dichtungsbahn folgenden Aufbau auf:The invention will now be brief based on a schematic sketch explained. The geomembrane has the following structure:

Oberschicht (1) aus TPO (Stärke: 0,1 bis 1 mm)
Unterschicht (2) aus TPE (Stärke: 0,1 bis 5 mm)
Glasgitter (3)Top layer ( 1 ) made of TPO (thickness: 0.1 to 1 mm)
Bottom layer ( 2 ) made of TPE (thickness: 0.1 to 5 mm)
Glass grid ( 3 )

Eine so aufgebaute Dichtungsbahn hat den Vorteil, daß die guten Alterungseigenschaften und die gute Temperaturbeständigkeit er­ halten bleibt, wobei die Verlegemöglichkeiten auf alle Bereiche ausgedehnt werden.A sealing membrane constructed in this way has the advantage that the good ones Aging properties and good temperature resistance holds, with the laying options on all areas be expanded.
