Abstract

The object of the invention is to find a combination comprising styrene-butadiene-styrene bitumen as highly elastic compound on the one hand and polyethylene or polypropylene on the other hand, from which highly elastic sheeting can be produced. The raw material combination is produced in the form of granules and is compounded together. The proportion of polyethylene or polypropylene is 30-95 %.

Description

Rohstoffgranulat zur Herstellung von DichtungsbahnenRaw material granulate for the production of waterproofing membranes

Die Erfindung betrifft einen Rohstoff, bestehend aus Polyethylen mit Bitumen, worin ein Kunststoff, bestehend aus Styrol-Butadien-Styrol, in Blockform eingearbeitet ist.The invention relates to a raw material consisting of polyethylene with Bitumen, in which a plastic consisting of styrene-butadiene-styrene, in block form is incorporated.

Es ist bereits bekannt, daß Dichtungsbahnen aus einem Rohstoff, bestehend aus Bitumen-Styrol-Butadien-Stryrol, hergestellt oder vergütet werden. Dieser Einsatz ist bis jetzt jedoch nur bei Selbstklebebahnen erfolgt. Ferner wird diese Kombination zur Vergütung von Bitumen-Dichtungsbahnen eingesetzt. Die selbstklebenden Dichtungsbahnen werden aufgrund der hohen Klebfähigkeit überlappt.It is already known that sealing sheets are made from a raw material from bitumen-styrene-butadiene-styrene, manufactured or remunerated. This use has so far only been done with self-adhesive sheets. Furthermore, this combination used for the compensation of bitumen waterproofing membranes. The self-adhesive waterproofing membranes are overlapped due to the high adhesive strength.

Bitumen- und Asphaltdachbahnen, auch Dachpappe genannt, werden im Heißbitumenverfahren verlegt. Die Erfindung hat es sich zur Aufgabe gemacht, diese Kombination Styrol-Butadien-Styrol-Bitumen, welche sehr weich und hochelastisch ist, mit einem Kunststoff - vorzugsweise Polyethylen oder aber auch Polypropylen - in der Art zu vergüten, daß eine hochfeste und elastische Dichtungsbahn entsteht, die dann beim Verlegen durch Heißluft verschweißt werden kann.Bitumen and asphalt roofing membranes, also called roofing felt, are used in the Hot bitumen process laid. The invention has set itself the task of this Combination of styrene-butadiene-styrene-bitumen, which is very soft and highly elastic is, with a plastic - preferably polyethylene or polypropylene - to be tempered in such a way that a high-strength and elastic sealing membrane is created, which can then be welded by hot air during laying.

Das Granulat wird hergestellt, indem 30 - 70 % Polyethylen in einem Doppelschneckenkneter mit dem Gemisch Styrol-Butadien-Styrol-Bitumen vernetzt und homogen zusammengeknetet werden. Aus dieser Knete wird das Material zu Granulat geformt. Dieses Granulat kann von normalen Extrudern und Kalanderanlagen zu Dichtungsbahnen verarbeitet werden.The granulate is made by adding 30-70% polyethylene in one Twin-screw kneader cross-linked with the mixture of styrene-butadiene-styrene-bitumen and be kneaded together homogeneously. The material turns into granules from this clay shaped. These granules can be used in standard extruders and calender systems to make geomembranes are processed.
