The invention discloses a fire retardant coating for an aluminium plate and a production process tereof. The fire retardant coating catalyst is prepared form sodium silicate, simethicone, an adhesionagent, an annexing agent, solvent, a catalyst, a thickening agent, an antibacterial agent, inorganic powder, a film-forming agent, an acid donor, a foaming agent, a synergistic agent, inorganic fillers, a carbonization agent, epoxy resin and cellulose ether; the production process comprises the following steps of raw material preparation, dispersion, grinding, inspection and package; the fire retardant coating is good in environment protection, can continuously exert a flameproof protection effect, is wide in application range, better in fireproof performance and stronger in adhesive strength,and has better chemical corrosion resistance, better heat resistance, better acid-base resistance and better electrical insulating performance; the fireproof performance is slightly affected by timeand environments, the coating further has the advantages of lasting fire resistance, high inflaming retarding efficiency and the like, the flame retardant effect of the coating is strengthened, the effective fireproofing time of the coating is prolonged, the preparation method is simple and convenient, and the efficiency is high.
