Abstract

L'invention se rapporte à une composition d'émulsion comportant un agent de polymérisation et/ou de réticulation et à des procédés d'utilisation de cette composition en vue d'améliorer les caractéristiques de fabrication, d'emballage, de transport, d'entreposage et de détonation d'explosifs contenant une émulsion. La présente invention concerne la régulation de la rhéologie d'une émulsion ou d'un explosif contenant une émulsion par la polymérisation et/ou la réticulation de la phase continue de l'émulsion grâce à l'utilisation de polybutadiène à terminaison hydroxy et d'agents de polymérisation et/ou de polybutadiène additionné d'anhydride maléique et d'agents de réticulation. La présente invention décrit des compositions et des procédés de polymérisation et de réticulation de compositions d'émulsions, qui permettent d'obtenir une émulsion dont la rhéologie peut être choisie de façon régulable, sans que l'intégrité de la réaction de l'explosif soit altérée. La composition décrite dans la présente invention se compose d'une émulsion d'eau dans l'huile contenant une phase combustible carbonée externe continue, qui est au moins partiellement polymérisée et/ou réticulée.
