AQUEOUS BINDER FOR INORGANIC FIBER OF HEAT-INSULATING/SOUND-ABSORBING MATERIAL AND HEAT-INSULATING/SOUND-ABSORBING MATERIAL OF INORGANIC FIBER

摘要

PPROBLEM TO BE SOLVED: To provide an aqueous binder for inorganic fibers, which can improve adhesion between inorganic fibers each other without deteriorating fluidity of the binder and strength of cured binder, and to provide a heat-insulating/sound-absorbing material of inorganic fibers, which uses the binder. PSOLUTION: The heat-insulating/sound-absorbing material of inorganic fibers is provided by applying an aqueous binder for inorganic fibers, which contains 0.1-10 pts.mass of aqueous silica sol and/or aqueous alumina sol per 100 pts.mass of resin component in a water-soluble/thermosetting resin composition in terms of solid content to the inorganic fibers to be heated and cured.
