A manufacturing method of a thermosetting water binder

Japanese Patent JP6219994

B2

Provided is a method for producing a thermosetting aqueous binder comprising a polycarboxylic acid and an amine-based compound serving as a crosslinking agent for the polycarboxylic acid and having two or more per molecule of at least one from between an amino group and an imino group, the method comprising: a blocking step for blocking at least a part of the carboxy groups of the polycarboxylic acid with a volatile basic compound to obtain a blocked polycarboxylic acid; and a mixing step for mixing the blocked polycarboxylic acid and the amine-based compound. According to such an invention, it is possible to reduce a precipitate and a viscous substance generated during production to a level sufficient for practical use.
