Title
(EN) ACRYLIC-BASED INJECTION MATERIALS WITH IMPROVED CURING PROPERTIES
(FR) MATÉRIAUX D'INJECTION À BASE D'ACRYLIQUE PRÉSENTANT DES PROPRIÉTÉS DE DURCISSEMENT AMÉLIORÉES
Abstract
(EN)
The invention is directed to a hydrogel forming composition comprising at least one water-soluble (meth)acrylic compound, at least one free radical initiator, at least one catalyst for free radical formation, and water, wherein the at least one catalyst for free radical formation is an amine compound of formula (I). The invention is also directed to a multiple-component composition, to a hydrogel, to use of the hydrogel forming composition for sealing of constructions, tunnels, or mines or for soil stabilization, to a method for sealing and/or filling of cracks, voids, flaws and cavities in a building structure, and to a use of at least one tertiary amine compound for reducing the gelling time of a hydrogel forming mixture.
(FR)
L'invention concerne une composition formant un hydrogel comprenant au moins un composé (méth)acrylique soluble dans l'eau, au moins un initiateur de radicaux libres, au moins un catalyseur de formation de radicaux libres et de l'eau, le ou les catalyseurs de formation de radicaux libres étant un composé amine de formule (I). L'invention concerne également une composition à constituants multiples, un hydrogel, l'utilisation de la composition formant un hydrogel pour l'étanchéification de constructions, de tunnels ou de mines ou pour la stabilisation du sol, un procédé d'étanchéification et/ou de remplissage de fissures, de vides, de défauts et de cavités dans une structure de construction, et une utilisation d'au moins un composé amine tertiaire pour réduire le temps de gélification d'un mélange formant un hydrogel.
