EPOXY RESINS CROSSLINKABLE AT ROOM TEMPERATURE

摘要

An epoxy resin is provided that is cross-linkable at room temperature, including the product of a reaction of a mixture including at least one epoxy function carrier derivative, chosen from the group consisting of non-polymeric, non-bio-sourced reagents and carriers of at least 3 epoxy end functions and biosourced, epoxidized lipidic derivatives, and at least one crosslinking agent, the ratio between the number of epoxy functions being kept constant independently of the composition of the mixture, the method for manufacturing same, and the use thereof in composite parts for the mechanical engineering or for building construction and in structural parts.

1. An epoxide resin comprising the product of the reaction of a mixture comprising:
at least
one non-biosourced non-polymer reagent bearing at least 3 epoxy end functions (CRx);at least one biosourced epoxidized lipid derivative; and at least one cross-linking agent;a ratio between the number of reactive functions of the cross-linking agent and the number of epoxy functions being kept constant independently of the constitution of the mixture, on the condition that:
CRx is not a compound having the following formula (a): in which n is an integer comprised between 1 and 20.
