摘要（英）：

The invention discloses a preparation method of polyurethane fireproof paint, which comprises the following steps: adding 78-82 mass parts of polypropylene glycol, 30-34 mass parts of adipic acid and 10-14 mass parts of dihydroxymethylpropionic acid into a reaction kettle, heating to 180 DEG C to react for 30 hours, adding 15-16 mass parts of acetone and 20 mass parts of toluene diisocyanate, uniformly stirring, reacting at 70 DEG C for 5 hours, adding 20-30 mass parts of ammonium iodide and 20-25 mass parts of pulverized asbestos while stirring, and continuing stirring for 4 hours to obtain the polyurethane fireproof paint. The industrial test on the product proves that the coating has favorable fire resistance, wear resistance, moisture resistance and dry cleaning fastness.
