Gegenstand des Patents 27 31 810 ist eine bituminöse, gegebenenfalls Kunststoffe enthaltende, Masse, die durch einen Gehalt an einer aus Altgummi erhaltenen und oberhalb von etwa 2000C siedenden Pyrolyseölfraktion gekennzeichnet ist; ferner ist dort ein Verfahren zur Herstellung dieser Masse angegeben, bei dem die Kunststoffe vor dem Einarbeiten in die bituminöse Masse in einer aus Altgummi erhaltenen und oberhalb von etwa 2000C siedenden Pyrolyseölfraktion gequollen oder gelöst werden.The subject of patent 27 31 810 is a bituminous mass, optionally containing plastics, which is characterized by a content of a pyrolysis oil fraction obtained from waste rubber and boiling above about 200 ° C.; a method for producing this mass is also given there, in which the plastics are swollen or dissolved in a pyrolysis oil fraction obtained from scrap rubber and boiling above about 200 ° C. before being incorporated into the bituminous mass.

Es wurde gefunden, daß eine schon oberhalb von etwa 1600C siedende Pyrolyseölfraktion in gleicher Weise eingesetzt werden kann.It has been found that a pyrolysis oil fraction boiling above about 160 ° C. can be used in the same way.

Das in Beispiel 1 und 2 verwendete Pyrolyseöl aus Altgummi entspricht in der Zusammensetzung des oberhalb 200°C siedenden Anteils dem in der DEPS 27 31 -310 charakterisierten ÖLThe pyrolysis oil used in Examples 1 and 2 from In terms of the composition of the portion boiling above 200 ° C, old rubber corresponds to that in DEPS 27 31 -310 characterized OIL

Die Verwendung der oberhalb etwa 160°C siedenden Pyrolyseölfraktion bringt für die Verarbeitung bituminöser Massen, wie z, B, in Dach- und Dichtungsbahnen, Schall- und Wärmedämmplatten, dauerelastischen Fugenvergußund Spachtelmassen, Bitumen-Kunststoffbahnen, Kunststoffbahnen und Selbstklebebahnen sowie Dichtungsmassen entscheidende Vorteile, nämlich:The use of those boiling above about 160 ° C Pyrolysis oil fraction brings for the processing of bituminous masses, such as, for example, in roofing and waterproofing membranes, Sound and thermal insulation panels, permanently elastic joint grouting and Leveling compounds, bitumen plastic sheets, plastic sheets and self-adhesive sheets as well Sealing compounds have decisive advantages, namely:

1. Senkung des Brechpunktes1. Lowering of the breaking point

2. Oxidationsverminderung des Bitumens2. Reduction of oxidation of bitumen

3. Erhöhung der Elastizität3. Increase in elasticity

4. Erhöhung der Duktilität4. Increase in ductility

5. Erhöhung des Adhäsionsvermögens ö. Erhöhung der Dehnfähigkeit5. Increase in the adhesion capacity. Increase in the elasticity

7. Verringerung der Härte7. Reducing hardness

8. Verbesserung der Lösungsfähigkeit für die zur Anwendung kommenden Kunststoffe im Bitumen8. Improvement of the solubility for the plastics used in the bitumen

9. Verkürzung der Rührzeiten9. Shortening the stirring times
