采用多羟基、多羧基的活性天然产物茶皂素为原料,与聚磷酸铵和季戊四醇在一定条件下反应,制备一种聚磷酸酯类茶皂素基三位一体新型环保膨胀型阻燃剂。采用傅里叶红外分析技术对阻燃剂进行了结构表征,采用综合热分析仪对阻燃剂的热降解性能进行了研究。结果表明,茶皂素与聚磷酸铵、季戊四醇发生反应,生成聚磷酸酯类茶皂素基膨胀型阻燃剂,且该阻燃剂具有良好的热稳定性,降解热释放较小,高温残留率高,最终的质量残留率高达30.77%。将制备阻燃剂用于阻燃涂料中,并采用氧指数测试仪和锥形量热仪研究了阻燃涂料的阻燃性能和热解性能。研究表明,茶皂素基三位一体膨胀型阻燃剂能显著提高涂料的阻燃性能,...

A novel polyphosphoester class trinity tea saponin based environmentally friendly intumescent flame retardant(TTS-IFR)was prepared by using the active natural product tea saponin containing multiple hydroxyl and carboxyl radicals as the raw material reacting with ammonium polyphosphate and pentaerythritol under specific conditions. Its structure characterization and thermal degradation properties were studied with FTIR spectrometer and simultaneous thermal analyzer. Tea saponin reacted with ammonium polyphosphate and pentaerythritol,and generated polyphosphoester class tea saponin-based trinit...
