Continuous preparation process, solvent-free and mastication sensitive pressure PSAs based on non-thermoplastic elastomers, and their application as a coating to produce self-adhesive articles.

摘要

Process for the continuous, solvent-free and mastication, self-adhesive mass (14) based on non-thermoplastic elastomers in a machine working continuously and having a feed zone (2) and a zone of manufacturing compound (5), It comprising a) introducing the solid components of the self-adhesive composition (14), such as elastomers and resins, into the feed zone (2) of the machine, optionally introduction of fillers, colorants and / or crosslinkers, b ) transport of the solid components of the self-adhesive composition (14) of the feed zone (2) to lazona Manufacturing compound (5), c) adding the liquid components of the self-adhesive composition, such as plasticizers, crosslinkers and / or other tackifying resins, to the area of ​​manufacturing compound (5), d) preparing a homogeneous self-adhesive composition (14) in the manufacture of compound (5) and e) discharging the self-adhesive composition.
