Zusammenfassung: | Verfahren zur Herstellung eines vorzugsweise haftklebrigen Klebstoffs unter Verwendung eines ersten Planetwalzenextruders und eines stromab angeordneten zweiten Entgasungsplanetwalzenextruders.
The invention relates to a method for producing a preferably adhesive glue using a first planetary roller extruder and a second degassing planetary roller extruder arranged downstream, wherein the first planetary roller extruder consists of an atmospherically operated filling and dispersing zone consisting of at least one roller cylinder, to which filling and dispersing zone the polymers forming the thermally vulcanisable meltable glue are supplied in a plasticized state, same are fed within the first third of the at least one roller cylinder; furthermore, downstream of the addition of the plasticized polymers, via an opening of the at least one roller cylinder, solid substances are added which are dispersed in the plasticized polymers in the filling and dispersing zone, wherein the solid substances contain at least thermal cross-linkers, and the flow temperatures of the central spindle and of the at least one roller cylinder are configured such that no gelling occurs, then the mixture of plasticized polymers and solid substances is supplied to a second degassing planetary roller extruder, which consists of a degassing zone consisting of at least one roller cylinder, and is degassed there, and the degassed mixture is then guided to a coating assembly. |
