Examples
Embodiment 1
[0028] Example 1 Add different proportions of TIPRG to polyester PET, mix evenly, extrude a sample strip with a diameter of about 3 mm at melting temperature with an XJ-01 extruder, and measure its limit with an HC900-2 oxygen index tester Oxygen index, the results are shown in Table 2.

[0030]
Embodiment 2
[0031] Example 2 Add different proportions of TIPRG and MCA to polyester PET, mix evenly, extrude a sample strip with a diameter of about 3mm at the melting temperature with an XJ-01 extruder, and measure it with an HC900-2 oxygen index measuring instrument The limiting oxygen index, the results are shown in Table 3.
[0032] Table 3 Flame retardant performance of flame retardant TIPRG and MCA compounded on PET
[0033]
[0034] It can be seen from Table 3 that when 12 parts of TIPRG and 8 parts of MCA are used in combination, the limiting oxygen index is increased by 2 compared with that of TIPRG used alone, reaching 30, which has a good flame retardant synergistic effect. And MCA is cheaper, which can reduce the cost.
Embodiment 3
[0035] Example 3 Add TIPRG and MPP in different proportions to polyester PET, mix well, extrude a sample strip with a diameter of about 3mm at melting temperature with an XJ-01 extruder, and measure it with an HC900-2 oxygen index measuring instrument The limiting oxygen index, the results are shown in Table 4.
[0036] Table 4 Flame retardant properties of flame retardant TIPRG and MPP compounded on PET
[0037]
[0038] It can be seen from Table 4 that when 12 parts of TIPRG and 8 parts of MPP are used in combination, the limiting oxygen index is increased by 2 compared with that of TIPRG used alone, reaching 30, which has a good synergistic flame retardant effect.
