Abstract

L'invention concerne un système de résine réactionnel comprenant un composant de résine et un composant durcisseur, les deux composants étant séparés avant traitement. Le composant de résine A renferme un polysiloxane, un composant fonctionnel époxy, et un liant hydraulique, et le composant durcisseur B renferme une polyamine et de l'eau, le rapport de l'eau au liant hydraulique dans le système de résine réactionnelle étant = 0,5. Pour ledit système, dans lequel les poids équivalents époxy sont compris entre 130 et 2000, le rapport de polysiloxane au composant fonctionnel époxy est de 1 : 5 à 95, et le rapport poids équivalent époxy à poids équivalent poly devrait s'élever à 1 : 0,5 à 1,5; de ce fait, il est recommandé d'ajuster un rapport eau/liant hydraulique à = 0,4. Principalement, lorsqu'on utilise ce système de résine réactionnelle comme mortier de joint, les avantages obtenus sont les suivants : aptitude au nettoyage améliorée, tendance à l'encrassement réduite, résistance élevée vis-à-vis des influences chimiques et climatiques, et stabilité de coloration notablement élevée.
