《Preparation of Poly(phosphoric acid piperazine) and Its Application as an Effective Flame Retardant for Epoxy Resin》
The mechanical properties of pure EP and EP/PPAP thermosets with different contents of PPAP additive are presented in Table 5.The tensile and flexural strength values of pure EP thermosets are 57.2 and 102.3 MPa,respectively.The tensile and flexural strength values of cured EP/PPAP composites gradually decrease with increasing the content of PPAP in EP thermosets.The tensile and flexural strength for EP/5 wt%PPAP thermosets are 44.7 and 85.2 MPa,which are decreased by 21.9%and 16.7%,respectively.This phenomenon may be attributed to that the incorporation of PPAP flame retardant additive hinders the formation of crosslinking network of epoxy resin thermosets.On the other hand,the thermosets decompose to a certain degree due to the presence of a number of acid hydroxyl groups in PPAP.
