Title:
AQUEOUS BINDER FOR INORGANIC FIBER HEAT-INSULATING SOUND-ABSORBING MEMBER, INORGANIC FIBER HEAT-INSULATING SOUND-ABSORBING MEMBER AND METHOD FOR PRODUCING INORGANIC FIBER HEAT-INSULATING SOUND-ABSORBING MEMBER
Document Type and Number:
WIPO Patent Application WO/2011/162277
Kind Code:
A1
Abstract:
Disclosed are: an aqueous binder for an inorganic fiber heat-insulating sound-absorbing member, which can be cured by heating at low temperatures and is capable of providing a strong binder cured product; an inorganic fiber heat-insulating sound-absorbing member which uses the aqueous binder; and a method for producing an inorganic fiber heat-insulating sound-absorbing member.
Specifically, an inorganic fiber heat-insulating sound-absorbing member is produced by applying an aqueous binder to inorganic fibers and heating the resulting inorganic fibers at 180-220°C. The aqueous binder contains 5.5-10 parts by mass of an ammonium salt of an inorganic acid per 100 parts by mass of the total of an acrylic resin that has an acid value of 350-850 mgKOH/g and a crosslinking agent that contains at least one alkanol amine. The ratio of the total mole number of hydroxy groups, amino groups and imino groups in the crosslinking agent relative to the mole number of carboxyl groups in the acrylic resin is 0.8-1.5. The pH of the aqueous binder is adjusted to 5.0-8.0 by a basic compound.
