摘要：
The modification of unsaturated polyester resins(UPR)inhibition formulas were prepared via compounding and curing reaction using 1, 3, 5-tri(2-allylaryloxy)- 2, 4, 6-triaryloxycyclotriphazene(TAPPCP) and hexa(2-allylaryloxy) cyclotriphazene(HAPPCP) as ablative fillers. The dispersivity, curing reaction kinetics and curing reaction mechanism of TAPPCP and HAPPCP with UPR were studied by FT-IR, X-ray energy spectrum and DSC, respectively. The non-isothermal curing reaction kinetic parameters were determined. The non-isothermal curing reaction kinetic equation was found. The results show that TAPPCP and HAPPCP have good compatibility with UPR, and the crosslinking structure can be formed by free radical copolymerization. The unsaturated double bond of TAPPCP and HAPPCP could reduce the activation energy of copolymerization with UPR. The characteristic curing temperature (Tp/Tf) of TAPPCP/UPR decreases from 88.37℃ and 109.58℃ to 83.58℃ and 99.42℃ with increasing the content of TAPPCP (from 0 to 20phr). The characteristic curing temperature (Tp/Tf) of HAPPCP/UPR decrease from 88.37℃ and 109.58℃ to 79.28℃ and 96.15℃ with increasing the content of HAPPCP (from 0 to 20phr). © 2021, Editorial Board of Journal of Explosives & Propellants.
