Examples
Embodiment 1
[0027] Example 1 Add different proportions of TIPRPG to polyester PET, mix evenly, use XJ-01 type extruder to extrude a sample with a diameter of about 3 mm at melting temperature, and use HC900-2 type oxygen index tester to measure its limit Oxygen index, the results are shown in Table 2.

[0029]
Embodiment 2
[0030] Example 2 Add different proportions of TIPRPG and MCA to polyester PET, mix evenly, use XJ-01 type extruder to extrude a sample with a diameter of about 3mm at melting temperature, and use HC900-2 type oxygen index tester to measure The limiting oxygen index, the results are shown in Table 3.
[0031] Table 3 Flame retardant properties of flame retardants TIPRPG and MCA compounded on PET
[0032]
[0033] It can be seen from Table 3 that when 12 parts of TIPRPG and 8 parts of MCA are used in combination, the limiting oxygen index is increased by 3 compared with that of TIPRPG alone, reaching 30, which has a good synergistic effect of flame retardancy. And MCA is cheaper, which can reduce the cost.
Embodiment 3
[0034] Example 3 Add different proportions of TIPRPG and MPP to polyester PET, mix evenly, use XJ-01 type extruder to extrude a sample with a diameter of about 3mm at melting temperature, and use HC900-2 type oxygen index tester to measure The limiting oxygen index, the results are shown in Table 4.
[0035] Table 4 Flame retardant properties of flame retardants TIPRPG and MPP compounded on PET
[0036]
[0037] It can be seen from Table 4 that when 12 parts of TIPRPG and 8 parts of MPP are used in combination, the limiting oxygen index is increased by 2 compared with that of TIPRPG alone, reaching 29, which has a good synergistic flame retardant effect.
