In this study, nano-titania as a UV resistance filler in different loadings, was added to the traditional ammonium polyphosphate (APP), pentaerythritol (PER) and melamine (MEL) coating. The effects of this synergistic effect were investigated in detail by using themogravimetric analysis (TGA), X-ray diffraction (XRD) and bunsen burner test. The TGA result approved that adding nano-TiO2 could increase the residue weight at final stage of burning. The XRF result indicated that anti-oxidation property of the coating was improved by incresing carbone content and decreasing oxygen content due to existance of nano-TiO2. The bunsen burner test showed that the best fire protection performance with the highest thermal stability was achieved with incorporation of 20 wt.% nanoTiO2.
