The inventor finds that the chlorinated hydrocarbon, the fatty alcohol and the alcohol ether solvent are used as the solvents, and the phosphate flame retardant is added, so that the flame retardant is good in flame retardance and good in temperature resistance, can be normally used at 200 ℃, is particularly suitable for spraying, and is not easy to block a nozzle. The reason the inventor believes is probably that the tri (xylene) phosphate not only has excellent flame retardancy, but also has a plasticizing effect and can interact with thermoplastic acrylic resin, cellulose acetate butyrate and rosin modified resin to soften a paint film. In addition, the prepared flame-retardant spray paint has the advantages of good quick drying property, uniform paint film, bright color, good weather resistance, no influence of air temperature and ultraviolet rays and high adhesion force by adopting the synergistic effect of thermoplastic acrylic resin BR-106 with the glass transition temperature of 50 ℃, cellulose acetate butyrate CAB-381-0.1 with the butyryl content of 38 wt% and rosin modified maleic resin. The reason the inventor guesses may be that the cellulose acetate butyrate CAB-381-0.1 with the butyryl content of 38 wt% can inhibit sagging and shrinkage cavities so as to reduce surface defects, can effectively inhibit plasticizer migration due to interaction with the tri (xylene) phosphate, has good compatibility with the cellulose acetate butyrate and rosin modified resin and the thermoplastic acrylic resin BR-106 with the glass transition temperature of 50 ℃, and further improves the adhesion and weather resistance of the flame retardant type spray marking paint. The inventor unexpectedly discovers in the further research process that the problems of thickening, pigment sedimentation and the like cannot be caused by long-time placement of the flame-retardant spray painting paint due to the interaction of the cellulose acetate butyrate CAB-381-0.1 with the butyryl content of 38 wt% and the rutile titanium dioxide color paste U4002 and the organic silicon defoamer KM-98, the fineness is not more than 3 mu m, the reason guessed by the inventor is probably that the cellulose acetate butyrate CAB-381-0.1 with the butyryl content of 38 wt% promotes the oriented arrangement of rutile titanium dioxide in resin, the dispersibility of the organic silicon defoamer KM-98 is improved, the fineness of the system is not more than 3 mu m, and the spraying is smooth.
In one embodiment, the flame retardant spray paint has a fineness of no more than 3 μm.

In one embodiment, the tack-free time of the flame retardant spray paint does not exceed 10 seconds.
In the invention, the detection method of the surface drying time is GB/T1728-1979.
