Abstract
(DE)
Es soll eine einfach anwendbare Haftklebmasse mit guten vibrationsdämpfenden Eigenschaften zur Verfügung gestellt werden, die über ein weites Temperaturspektrum hinweg zur Verfügung stehen. Dies gelingt mit einer Zusammensetzung zur Herstellung einer Haftklebmasse, die a) mindestens ein mehrere Si-gebundene Alkyl-Gruppen aufweisendes Organopolysiloxan, enthaltend mindestens zwei Si-gebundene Alkenylgruppen; b) mindestens ein mehrere Si-gebundene Aryl-Gruppen aufweisendes Organopolysiloxan, enthaltend mindestens zwei radikalisch vernetzbare Substituenten; und c) mindestens einen Radikalbildner enthält. Gegenstand der Erfindung ist auch eine Haftklebmasse, die durch thermische Vernetzung einer erfindungsgemäßen Zusammensetzung erhältlich ist.
(EN)
The invention aims to provide an easy-to-use adhesive compound with good vibration-damping properties which are available across a broad range of temperatures. This is achieved using a composition for producing an adhesive compound, containing: a) at least one organopolysiloxane that comprises multiple Si-bonded alkyl groups, and contains at least two Si-bonded alkenyl groups; b) at least one organopolysiloxane which comprises multiple Si-bonded aryl groups and contains at least two radically cross-linkable substituents; and c) at least one radical former. The invention also relates to an adhesive compound that can be obtained by thermally cross-linking a composition according to the invention.
(FR)
L'invention vise à mettre au point une matière autoadhésive facile à utiliser présentant de bonnes propriétés d'amortissement des vibrations, ces propriétés se manifestant sur un large spectre de températures. Cet objectif est atteint grâce à une composition pour fabriquer une matière autoadhésive qui contient a) au moins un organopolysiloxane présentant plusieurs groupes alkyle liés au Si et contenant au moins deux groupes alcényle liés au Si, b) au moins un organopolysiloxane présentant plusieurs groupes aryle liés au Si et contenant au moins deux substituants pouvant être réticulés par voie radicalaire, et c) au moins un générateur de radicaux. L'invention concerne également une matière autoadhésive pouvant être obtenue par réticulation thermique d'une composition selon l'invention.
