Uso de una masa de mortero de múltiples componentes a base de epóxido-amina
Uso de un agente endurecedor híbrido que contiene una mezcla de (a) al menos una amina, seleccionada entre aminas alifáticas, alicíclicas y aromáticas, donde la amina presenta por molécula en promedio al menos dos átomos de hidrógeno reactivos, en cada caso unidos a un átomo de nitrógeno, como agente endurecedor y (b) una resina de novolaca de fórmula general (I):**Fórmula** donde R1, R2, R3 y R4 en cada caso independientemente entre sí son hidrógeno o un radical alquilo C1-C15 no ramificado o ramificado y n es de 1 a 12, donde la resina de novolaca está contenida en una cantidad del 30 % al 45 % en peso, con respecto al peso total del agente endurecedor híbrido (a) y (b), como agente acelerador, como agente endurecedor en masas de mortero de múltiples componentes a base de epóxido, excepto revestimientos, para el anclaje químico de elementos de fijación en orificios perforados.
Described is the use of a hardening composition for epoxide-amine-based, multicomponent mortar compositions, particularly the use of one of these epoxide-amine-based, multicomponent mortar compositions for chemical fastening purposes. The multicomponent mortar composition contains (A) a resin component, which comprises as a curable compound at least an epoxide resin and optionally at least one reactive diluent, and (B) a hardener component, which comprises a hybrid hardener, wherein the resin component (A) and/or the hardener component (B) optionally comprises other ingredients selected from among inorganic and/or organic compounds. The hybrid hardener is a mixture of (a) at least one amine, selected from among aliphatic, alicyclic, or aromatic amines, as a hardener, and (b) a novolac resin as catalyst, wherein the novolac resin is contained in a quantity of 30 to 45 percent by weight, relative to the total weight of the hybrid hardener. The use of the hybrid hardener results in a rapid curding of the multicomponent mortar composition, even at low temperatures, with a complete through-curing of the mortar composition. High load values of the cured mortar composition both at low temperatures (+5° C.) and at high temperatures (+50° C.) and improved creep resistance at high temperatures (+50° C.) are hereby achieved. In addition, one can entirely omit the use of free phenols.
