Abstract | It was first proposed to use 2-(2-hydroxyphenyl) phenyl phosphonic acid (HPPA), which is hydrolysis product of DOPO, has a structure more similar to EP, to replace DOPO in the preparation of flame retardant, and finally synthesized a highly efficient liquid flame retardant DP based on HPPA, the theoretical phosphorus content of DP is up to 17.5wt%, so EP can achieve excellent flame retardant/inhibit combustion effect with a small amount addition of DP. For example, the LOI of EP/DP6.0 is increased to 41.2 % and reaches the V-0 rate of UL-94, the PHRR and THR are reduced by 52.4 % and 45.2 % respectively, in addition, the addition of DP in small quantities does not destroy the overall performance of EP, maintains and improves the excellent mechanical and thermal properties of epoxy resin as a whole, and DP has excellent curing promoting effects, meeting the processing and use requirement of high performance EP. It is better than DOPO overall and has good application prospects. |
