The title finishing fire retardant coating was prepared using phenolic modified acrylic resin as film former, and fire retardant synergistic agent and aluminium silicate, Based on orthogonal experiment, the effects of dosages of aluminium silicate, fire retardant synergistic agent and phenolic resin on fire resistant time of the fire retardant coating were studied. The physicochemical and fire retardant properties were tested according to the standard GB 12441-2005. The results showed that the sequence of influencing degree from large to small was: fillers, fire retardant synergistic agent and phenolic resin; and the optimal mixture ratio was: boron-modified phenolic resin 34%, acrylic resin 42%, fire retardant synergistic agent 10% and alumina silicate 14%; the data of the coating's physicochemical property reached or exceeded the requirements of national standards, adhesion grade 1, impact 40 cm,and the fire resistant time 43 min.
