Title (EN) REACTIVE RESIN MANUFACTURE
(FR) PRODUCTION DE RESINE REACTIVE
Abstract:
(EN) A method for the manufacture of one component, heat curable, thermosettable, epoxy resin systems and their placement in convenient container types, sizes and shapes, which comprises mixing: (A) epoxy resins, or epoxy containing compounds; (B) an amine solidifying system present in insufficient quantities to cause gelation after all the amino hydrogen atoms are consumed by epoxy groups, under the reaction conditions chosen for (A) and (B), and which yields a product with a Kofler Heat Bank melting point of less than 55 °C and melting point stability of at least six months at normal workshop temperatures; optionally (C) a hardener system for (A) and the reaction product of (A) and (B) which is different from (B) and remains substantially unreacted under the conditions of reaction chosen for (A) and (B) with (A) and (B); optionally (D) other additives that may be required to modify the physical properties of the cured or uncured composition; and optionally (E) an expanding agent in such a way that very little reaction is allowed to take place during the mixing operation between (A) and (B) and most of it takes place in the final shape or container it is needed in before further melt or other processing, provided that the reaction between (A) and (B) does not generate enough heat in the chosen shape or container to significantly activate reaction between the remaining epoxy groups and hardener (C), or expanding agent (E).
(FR) L'invention concerne un procédé de production de systèmes de résine époxy, thermodurcissables, polymérisables à chaud, à un seul constituant et leur transfert dans des récipients dont le type, la dimension et la forme sont adaptés. Le procédé de production de ces systèmes de résine époxy consiste à mélanger: (A) des résines époxy ou des composés époxydiques; (B) un système d'amines solidifiant présent dans des quantités insuffisantes pour induire la gélification après que tous les atomes d'hydrogène amino aient été épuisés par les groupes époxy, dans des conditions de réaction choisies pour (A) et (B), ce système donnant naissance à un produit se caractérisant par un point de fusion, mesuré suivant la norme Kofler Heat Bank, inférieur à 55 °C et une stabilité du point de fusion d'au moins six mois à des températures ambiantes normales; facultativement (D) d'autres additifs qui peuvent être nécessaires pour modifier les propriétés physiques de la composition durcie ou non durcie; et facultativement (E) un agent porogène prévu de telle sorte que seule une faible réaction puisse se produire pendant la phase de mélange entre (A) et (B) et que la majeure partie de cette faible réaction se produise lorsque la substance a pris sa forme finale ou se trouve le récipient final nécessaire avant un autre mélange ou un autre traitement, à condition que la réaction entre (A) et (B) ne génère pas suffisamment de chaleur lorsque la substance a pris la forme choisie ou se trouve dans le récipient choisi pour activer de manière significative la réaction entre les groupes époxy restants et le durcisseur (C) ou l'agent porogène (E).
