Abstract

Abstract Rigid polyurethane foams (RPUFs) were synthesized with chicken feather protein using the “one-step method” of all-water foaming. Thermogravimetry, pyrolysis kinetics analysis, Cone calorimetry and smoke density (Ds) were used to investigate the effects of chicken feather protein on thermal stability and combustion performance of RPUFs. The results showed that the modified RPUFs with 2.5 wt% chicken feather protein (RPUF-CF1) had the lowest mass loss, the highest integrated program pyrolysis temperature, the highest activation energy, the lowest Ds (13.3), the highest light transmittance (79.3 %), the lowest heat release rate (22.0 kW/m2 and 30.6 kW/m2) and total heat release (2.4 MJ/m2 and 2.8 MJ/m2), which indicated that RPUF-CF1 had better thermal stability and combustion performance. The current research results provide a useful reference for the preparation of RPUFs with good thermal stability by bio-based modification.

鸡毛蛋白对硬质聚氨酯泡沫塑料热稳定性和燃烧性能的影响

摘要以鸡毛蛋白为原料，采用全水发泡的“一步法”合成了硬质聚氨酯泡沫塑料。采用热重法、热解动力学分析、锥形量热法和烟密度法研究了鸡毛蛋白对RPUFs热稳定性和燃烧性能的影响。结果表明，用2.5 wt%鸡毛蛋白（RPUF-CF1）具有最低的质量损失、最高的综合程序热解温度、最高的活化能、最低的Ds（13.3）、最高的透光率（79.3 %), 最低放热率（22.0 kW/m2和30.6 kW/m2）和总热量释放（2.4 MJ/m2和2.8 MJ/m2），表明RPUF-CF1具有较好的热稳定性和燃烧性能。目前的研究结果为通过生物基改性制备具有良好热稳定性的RPUFs提供了有益的参考。

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.
