A series of (2-hydroxyethylmethacrylate)(n-propoxy)cyclotriphosphazenes (HPCP) has been prepared by the reaction of N3P3Cl6 with n-propanol and 2-hydroxyethylmethacrylate (HEMA) sequentially in the appropriate solvents. These phosphazene compounds are characterized by a combination of Fourier transform infrared, ultraviolet, and nuclear magnetic resonance spectroscopies. It was found that the compounds were soluble in most of the organic solvents, exhibited an absorption between 207–216 nm, and were curable by UV irradiation. After curing, the surfaces of the HPCP-coated woodblocks were transparent and had a fire-retardant property, which has been ascribed to the intumescent behavior during the burning process. © 1998 John Wiley & Sons, Inc.

The purpose of this research was to evaluate the influences of filler type and its content on the performance of a water-based intumescent fire-retardant coating. Three fillers (vermiculite, celite, and aluminum hydroxide) were added to the intumescent paint formulation. The thermal and fire protective properties were studied with thermogravimetric analysis (TGA), torch test, electrical furnace, scanning electron microscopy (SEM), and Fourier transform infrared analysis (FTIR). The results showed that adding fillers into coatings up to 3% could improve the intumescent coating's behavior and increase its endurance against flames. Of the three fillers used, vermiculite showed a better performance in the torch test, attributed to its chemical and physical structure. Vermiculite has low thermal conductivity and is considered an appropriate filler for heat-insulation. The final back-plate temperatures in the torch test for the vermiculite-containing samples were around 100°C–150°C lower than that of other samples. Moreover, vermiculite's addition improved the coating's expansion by 10% compared with the control sample's. The vermiculite sample's char layer morphology showed a uniform cell size distribution, indicating structural robustness. The coating samples successfully transformed polypropylene flammability from highly flammable to V0 level in the UL 94 vertical burning test standard. The results showed that vermiculite could improve intumescent paint's fire resistance and be used as an enhancer in intumescent coating formulations. 相似文献
