Process for the continuous, solvent and mastication free production of non-thermoplastic elastomers based self-adhesive compositions

摘要

The process comprises: (a) addition of the solid components to the filling section; (b) transfer of the solid components to the compounding section; (c) addition of the liquid components such as plasticizers, crosslinking agents and/or other tackifying resins to the compounding section; (d) production of a homogeneous self adhesive composition in the compounding section and (e) discharge of the composition (I). A process for the continuous, solvent free and mastication free production of self-adhesive compositions (I) based on non-thermoplastic elastomers is carried out in a continuously working machine having a filling section and a compounding section. The process comprises: (a) addition of the solid components such as elastomers and resins to the filling section and optionally addition of fillers, coloring agents and/or crosslinking agents; (b) transfer of the solid components to the compounding section; (c) addition of the liquid components such as plasticisers, crosslinking agents and/or other tackifying resins to the compounding section; (d) production of a homogeneous self adhesive composition in the compounding section and (e) discharge of the composition (I). An Independent claim is included for a self adhesive tape comprising the composition (I) applied to at least one side of a strip like material.
