超薄（CB）型钢结构膨胀防火涂料（UFRC）在燃烧过程中可形成耐火隔热保护层,提高钢结构耐火极限。选用氨基树脂、改性丙烯酸树脂为基体树脂,以多聚磷酸铵（APP）、季戊四醇（PER）、三聚氰胺（MEL）为膨胀阻燃体系,以氢氧化铝（AH）为协效剂,制备了抗静电膨胀型防火涂料（AUFRC）。用红外（FTIR）、XRD等方法对防火涂料及其燃烧残渣进行了分析,初步探讨了阻燃机理。当基体树脂（wt（氨基树脂）∶wt（丙烯酸树脂）=1∶2）为80份,APP为25份,PER为15份,MEL为10份,AH为5份时,制备的防火涂料阻燃、抗静电等综合性能最佳。

The steel structure can be protected by ultra-thin fire retardant coating (UFRC),due to the fire insulation of the protection layer formed during the combustion. In this article, the antistatic ultra-thin fire retardant coating (AUFRC) for steel structure was prepared with acrylic resin and amino resin as resin matrix, ammonium polyphosphate (APP),pentaerythritol (PER) and melamine (MEL) as flame retardant (IFR) system and aluminium hydroxide (AH) as synergists. The AUFRC and its ignitionresidue were tested by FTIR and XRD. The flame retardant mechanism was studied. The results show that the AUFRC exhibits good fire retarding properties and excellent antistatic performance,when prepared with 80 portions resin matrix (acrylic resin:amino resin=1:2,wt:wt), 25 portions APP, 10 portions MEL and 5 portions AH.
