FIELD: chemistry.
SUBSTANCE: invention relates to aqueous adhesive substance for inorganic material with excellent adhesion to inorganic material. Aqueous adhesive substance for inorganic material contains copolymer (A) containing unsaturated monobasic carboxylic acid, unsaturated polycarboxylic acid, or anhydride of unsaturated polycarboxylic acid (a1), and alkyl composite ester of (meth)acrylic acid (a2), in which alkyl contains 2-30 carbon atoms, as composing monomers, saccharide (B), polycarboxylic acid (C) with 4-24 carbon atoms, and water.
EFFECT: invention provides high adhesion of aqueous adhesive substance with inorganic material, such as mineral wool, which additionally gives beneficial water-resistance and rigidity to a product of glued inorganic material.
