Study on flame retardant properties and thermal stability of synergistically modified polyurethane foam with ammonium polyphosphate and barium phytate
Barium phytate (Pa–Ba) was prepared by phytic acid and barium carbonate, and then the flame-retardant modified polyurethane foam (PUF) was synergized with Pa–Ba and ammonium polyphosphate (APP). The flame retardant properties and thermal stability of the modified PUFs were investigated by thermogravimetric analysis, cone calorimetry (CONE) and smoke density (Ds). The results showed the modified PUF with the addition of 5 % Pa–Ba and 10 % APP (PUF-A10-PB5) had the highest integral programmed decomposition temperature and the activation energy, indicating that its thermal stability was better compared with other samples. In addition, PUF-A10-PB5 had the lowest total heat release under different radiation intensities, and it had the smallest Ds and the highest light transmittance under the flame and flameless condition. The current results indicated that PUF-A10-PB5 had better flame-retardant properties and thermal stability, which can provide a useful reference for future experimental studies on the flame retardant properties of phytate-modified PUF.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
