FLAME-RETARDANT AQUEOUS COATING COMPOSITION, AND FLAME-RETARDANT COATING FILM AND BUILDING BOARD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a flame-retardant aqueous coating composition, capable of forming a coating film with good flame retardancy on a building, a building material or the like.SOLUTION: A flame-retardant aqueous coating composition contains: (A) an aqueous binder resin; and (B) a flame retarder. Preferably, the flame-retardant water-based coating composition further contains (C) an inorganic layered compound. As the inorganic layered compound (C), a non-swellable layered silicate salt and a swellable layered silicate salt are suitably used.
