Title
(EN) LIGNIN-ENHANCED BUTYL RUBBERS
(FR) CAOUTCHOUCS BUTYLE RENFORCÉS PAR DE LA LIGNINE
Abstract
(EN)
Halogenated butyl rubbers are provided comprising lignins and co-reinforcing agents, where the ratio of the lignin to the co-reinforcing agent is selected so as to effectively modulate advantageous properties of the vulcanizate. The advantageous properties are achieved when using a ratio of lignin to the co-reinforcing agent, such as carbon black or silica, that is higher than in a reference vulcanizate, in effect the substitution of lignin for conventional reinforcing agents improves the reinforcement of the vulcanizates.
(FR)
L'invention concerne des caoutchoucs butyle halogénés comprenant des lignines et des agents de co-renforcement, le rapport entre la lignine et l'agent de co-renforcement étant sélectionné de manière à moduler efficacement les propriétés avantageuses du vulcanisat. Les propriétés avantageuses sont obtenues dès lors que l'on utilise un rapport entre la lignine et l'agent de co-renforcement, par exemple du noir de carbone ou de la silice, supérieur à celui observé dans un vulcanisat de référence. En effet, le remplacement par de la lignine des agents de renforcement classiques améliore le renforcement des vulcanisats.
