Abstract
Disclosed is an aqueous binder for an inorganic-fiber heat-insulating sound-absorbing member, comprising a polycarboxylic acid and a crosslinking agent for the polycarboxylic acid, in which the polycarboxylic acid comprises a polycarboxylic acid having a weight average molecular weight of 1000 to 20000 and an acid value of 500 to 900 mgKOH/g; the crosslinking agent at least comprises a polyamine without a hydroxyl group, the polyamine having at least one of an amino group and an imino group and having a weight average molecular weight of 100 to 500 and an amine value of 1150 to 1650 mgKOH/g, and a polyol without an amino group and an imino group, the polyol having a hydroxyl group and having a weight average molecular weight of 90 to 250 and an alcohol valence of 3 or more; the ratio of the total mole of the hydroxyl group, amino group and imino group in the crosslinking agent relative to the mole of the carboxy group in the polycarboxylic acid is 0.3 to 1.2; and the ratio of the total mole of the amino group and imino group in the crosslinking agent relative to the total mole of the hydroxyl group, amino group and imino group in the crosslinking agent is 0.01 to 0.2.
