The present invention discloses a fire retardation coating material, a preparation method and uses thereof. The coating material comprises, by weight, 20-40% of a polyvinyl chloride paste resin, 5-10% of a polytetrafluoroethylene suspension resin, 20-30% of an auxiliary agent part (a plasticizer, a heat stabilizer, an anti-ultraviolet agent, a sterilization agent, and a fire retardation agent), 5.0-10% of titanium dioxide, 3-5% of calcium carbonate, and the balance of a solvent part. According to the present invention, the polyvinyl chloride paste resin, the polytetrafluoroethylene suspension resin, the plasticizer, the heat stabilizer, the anti-ultraviolet agent, the sterilization agent, the fire retardation agent, the titanium dioxide and the calcium carbonate are adopted as the raw materials, and titanium dioxide slurry preparing, mixing, viscosity adjusting and a series of processes are performed to prepare the fire retardation coating material; and the PET textile cloth coated with the coating material of the present invention can be used in the field of PET tarpaulins, and has the good fire retardation effect.
