Document Type and Number:
WIPO Patent Application WO/2023/128018
Kind Code:
A1
Abstract:
The present invention provides an epoxy foaming composition containing a carboxyl group for the manufacture of a ship structure, the composition comprising: a main material including a) a first epoxy resin, b) a second epoxy resin containing a liquid bisphenol-based epoxy resin or a modified epoxy resin modified with an aliphatic amine compound, and a mixture thereof, c) a silicon compound containing a silicon hydrogen compound, d) a reactive surfactant, and e) a filler; and a curing agent which is an amine-based and polyamide-based curing agent containing an ionomer, and contains 0.1 to 2 parts by weight of the ionomer with respect to 100 parts by weight of the total curing agent, wherein the content of the carboxyl group in the composition of the main material is 15% to 30%. The epoxy foaming composition containing a carboxyl group for the manufacture of a ship structure of the present invention comprises a curing agent, a silicon compound, and a filler of a specific composition in an epoxy resin, such that the composition has excellent weather resistance while satisfying enhanced mechanical properties. In addition, the composition has a uniform close-cell structure and can be cured at room temperature (24°C) such that there is no need for additional curing equipment.
