Abstract
PURPOSE: To produce the titled foam having fine dense cells, a high colosed- cell content, a low water absorption and excellent friability resistance, by carrying out foaming in the presence of a specified surfactant and an acidic curing agent by use of a low-boiling organic blowing agent.
CONSTITUTION: In producing a phenol resin foam in the presence of a surfactant and an acidic curing agent with the aid of a low-boiling organic blowing agent (e.g., trifluorotrichloethane), the phenol resin foam is produced by using, as said surfactant, 0.1W10pts.wt. per 100pts.wt. resol type liquid phenol resin, at least one compound selected from the group consisting of a long-chain fatty acid having at least two hydroxyl groups in the long chain or an ethoxylated product of its glyceride (e.g., ethoxylated product of epoxidized soybean oil, ethoxylated dihydroxystearic acid). Curing of resin and release of blowing agent are balanced well and, accordingly, it is possible to produce a good-quality foam having fine, uniform cells in a high closed cell content, high compression and bending strength and less friability.
