Abstract

N,N′-bis(2,4-di(acryloyloxyethyl)-[1,3,5]-triazin-2-yl)-hexane-1,6-diamine(BDAETH) and 2,2-dimethyl-1,3-propanediol glycerol-methacrylate phosphate (PGMH) were synthesized from cyanuric chloride and phosphorus oxychloride. BDAETH and PGMH were further blended in different ratios to prepare UV-curable intumescent flame-retardant coatings. The thermal behaviors of their cured films were studied by thermal gravimetric analysis, and the results showed that degradation process of cured blend films could be divided into three degradation regions. The degradation mechanism was further investigated by in situ Fourier transform infrared spectra. The flame-retardant properties and the expansion process of the intumescent flame-retardant coatings were further monitored by limiting oxygen index and a self-made equipment, which indicated the synthetic effect between BDAETH and PGMH.
