FOAMABLE COMPOSITION BASED ON EPOXY RESIN

PROBLEM TO BE SOLVED: To obtain the subject composition capable of providing a foam of uniform and dense foam structure having a high foaming rate by compounding a liquid epoxy resin, an ordinary temperature curing type curing agent, and a water-containing phenolic resin in specific amounts, respectively. SOLUTION: This composition preferably comprises (A) 100 pts.wt. of a liquid epoxy resin, (B) 15-130 pts.wt. of an ordinary temperature curing type curing agent (preferably a water-soluble resol type phenolic resin) and (C) 0.1-60 pts.wt. of a phenolic resin containing water. The composition may further contain (D) a foam stabilizer (preferably a silicone surfactant) and (E) a nucleating agent (preferably calcium carbonate, talc, clay or the like) in amounts of 0.05-5 pts.wt. and 0.1-50 pts.wt., respectively, per 100 pts.wt. of the component A. The content of water contained in the phenolic resin the component C is preferably 1-50 wt.%. Foams produced from the composition can suitably be used e.g. as the interior or exterior materials of automobiles.
