Dachpappe.
Es ist bekannt, dass die üblichen, mit Kautschukfirnis getränkten Dachpappen bei längerem Lagern brüchig werden. Diesem Übelstande wird der Erfindung gemäss dadurch abgeholfen, dass man dem liautschukfirnis Stearinpech beimengt. Der Vorgang ist dabei folgender :
In einem offenen Kessel wird Leinöl auf zirka 1000 C erhitzt, worauf man pro 5 Gewichtsteile Leinöl zirka 4 Gewichtsteile Kautschukabfäl1e portionenweise und unter beständigem Umrühren einträgt.
Gleichzeitig schmilzt man in der Imprägnierpfanne eine Gewichtsmenge Stearinpech, welche gleich gross oder auch etwas grösser ist als die Menge bereiteten Kautscbuknrnisses, und dem nüssig gewordenen Stearinpech wird dann die heisse Kautschuklösung portionenweise und unter beständigem Umrühren zugesetzt. Es resultiert dabei eine vollkommen homogene, dtcknüssige Masse, mit welcher die Pappe in gewöhnlicher Weise imprägniert wird.

Roofing felt.
It is known that the usual roofing felts soaked with rubber varnish become brittle when stored for a long time. According to the invention, this disadvantage is remedied by adding stearic pitch to the liautschuk varnish. The process is as follows:
In an open kettle, linseed oil is heated to approx. 1000 ° C., after which approx. 4 parts by weight of rubber waste per 5 parts by weight of linseed oil are introduced in portions and with constant stirring.
At the same time, an amount by weight of stearin pitch is melted in the impregnation pan, which is the same or slightly larger than the amount of the prepared chewy cake, and the hot rubber solution is then added in portions to the nutty stearin pitch while stirring constantly. The result is a completely homogeneous, dense mass with which the cardboard is impregnated in the usual way.
