FOAMABLE RESOL-TYPE PHENOL RESIN MOLDING MATERIAL AND PHENOL RESIN FOAM

摘要

Providing a foamable resol-type phenolic resin forming material that gives a phenolic resin foam product which is excellent in flame retardancy, fireproofness, and long-term stability of thermal insulation property, suffers from a reduced amount of dimensional change during its formation, has an improved strength and improved brittleness, absorbs less water and has a higher pH than conventional foam products, thereby exhibiting an excellent property of preventing corrosion of a contact member. Also providing the phenolic resin foam product having such properties. The foamable resol-type phenolic resin forming material comprises at least a liquid resol-type phenolic resin, a blowing agent, and an acid curing agent, further comprises a nitrogen-containing bridged cyclic compound and a silicone oil as additives, and the blowing agent is a chloropropane.
