Document Type and Number:
WIPO Patent Application WO/2022/186203
Kind Code:
A1
Abstract:
The present invention provides an epoxy-based composition that has excellent fluidity, low heat generation during curing, cures in a short time at room temperature, and can be used to obtain a cured product having excellent mechanical strength. An epoxy-based composition according to the present invention includes: 100 parts by weight of an epoxy resin (A) having an aromatic ring and an epoxy group in a molecule; a reactive amine compound (B) having a reaction rate constant k of 0.10-0.37 min-1 and including a polyamine (B1) and/or a polyamide amine (B2); and a catalyst compound (C) including a tertiary amine (C1) and/or a nitrogen-containing aromatic heterocyclic compound (C2), and having an integrated heat quantity of 100 J/g or more, a maximum heat flow of 0.08 W/g or more, and a temperature of 130°C or less indicating a maximum heat flow. The ratio of the amount of active hydrogen of the reactive amine compound (B) to the amount of epoxy of the epoxy resin (A) [the amount of active hydrogen of the reactive amine compound (B)/the amount of epoxy of the epoxy resin(A)] is 0.3-0.8.
