The antioxidant is bis (2, 4-dicumylphenyl) pentaerythritol diphosphite.
Examples 2,
The difference from example 1 is that 1.5kg of the gas-phase flame retardant and 1.5kg of the condensed-phase flame retardant were used in step S1. The compatibilizer is polyethylene grafted glycidyl methacrylate.

The difference from example 1 is that: in step S1, 90kg of polyethylene, 5kg of gas phase flame retardant, 5kg of compatibilizer and 0.5kg of antioxidant were dried at 80 ℃ and mixed to obtain a mixture. No coacervate phase flame retardant was added.
Comparative examples 2,
The difference from example 1 is that: in step S1, 90kg of polyethylene, 5kg of condensed phase flame retardant, 5kg of compatibilizer, and 0.5kg of antioxidant were dried at 80 ℃ and mixed to obtain a mixture. No gas phase flame retardant was added.
The effect proves experiment: the polyethylene, the phosphaphenanthrene and the polyphosphazene double-base synergistic flame-retardant composite materials obtained in the above example 1, example 2, comparative example 1 and comparative example 2 were all injection-molded into standard bars for the following tests.
Vertical burning performance: the test was carried out according to the vertical method of GB/T2408-1996, with at least 5 standard bars per set, i.e., 5 bars for example 1, example 2, comparative example 1 and comparative example 2.
The flame retardant grade, namely the property of the substance or the treated material for obviously delaying the flame spread, is classified according to a grading system, and the flame retardant grade is gradually increased from V2 to V1 to V0: v0 shows that after the sample is subjected to combustion test for 10 seconds twice, the flame is extinguished within 30 seconds, and no combustible substance can fall off; v1 shows that after the sample is subjected to two 10-second combustion tests, the flame is extinguished within 60 seconds, and no combustible can fall off, and V2 shows that after the sample is subjected to two 10-second combustion tests, the flame is extinguished within 60 seconds, and the combustible can fall off.

the notch impact strength was notched by 4mm using a notch sampling machine and tested in accordance with GB/T1043-2008.
The results of the performance tests obtained above are shown in table 1:
TABLE 1 composite Performance test
From the test results in table 1, it can be seen that the mechanical properties of the general polymer-based flame retardant material are reduced with the increase of the content of the flame retardant, compared to the conventional material, in the sample prepared by the technical scheme of the present invention, while the difference between example 1 and example 2 in the present invention is that: the amount of the reactive phosphaphenanthrene flame retardant used in example 1 was 2.5kg, the amount of the reactive polyphosphazene used was 2.5kg, the amount of the reactive phosphaphenanthrene flame retardant used in example 2 was 2kg, the amount of the reactive polyphosphazene used was 2kg, and the other experimental conditions were the same. In the examples 1 and 2, it can be seen that, due to the increase of the content of the flame retardant, the mechanical properties of the polyethylene flame-retardant composite material are not reduced, and the mechanical properties of the polyethylene flame-retardant composite material are increased, because the reaction hydroxyl groups in the reaction type phosphaphenanthrene flame retardant and the reaction hydroxyl groups in the reaction type polyphosphazene react with the epoxy groups in the polyethylene grafted glycidyl methacrylate compatibilizer, the polyethylene chain segment in the polyethylene grafted glycidyl methacrylate compatibilizer has good compatibility with the polyethylene resin matrix, the interfacial adhesion between the reaction type phosphaphenanthrene flame retardant and the reaction type polyphosphazene is enhanced, and the interfacial adhesion between the reaction type phosphaphenanthrene flame retardant and the polyethylene matrix is increased, the interfacial strength between the reactive polyphosphazene and the polyethylene matrix is improved, so that the polyethylene flame-retardant composite material forms a network cross-linked structure, and the mechanical property of the polyethylene flame-retardant composite material is better along with the increase of the use amount of the reactive phosphaphenanthrene and the reactive polyphosphazene, so that the reactive phosphaphenanthrene and the reactive polyphosphazene have the flame retardant effect in the polyethylene flame-retardant composite material and have the effect of interfacial compatibilization; the two polyethylene flame retardant composites of example 1 and example 2 were both rated V0, except that the difference in the amounts of the reactive phosphaphenanthrene and the reactive polyphosphazene resulted in the difference in the mechanical properties of the polyethylene flame retardant composites. The difference between the example 1 and the comparative examples 1 and 2 is that the addition amount of the reactive phosphaphenanthrene and the reactive polyphosphazene in the raw material formula of the comparative example 1 is 2.5kg, the sum of the flame retardants is 5kg, the addition amount of the reactive phosphaphenanthrene in the raw material formula of the comparative example 1 is only 5kg, the addition amount of the reactive polyphosphazene in the raw material formula of the comparative example 2 is only 5kg, and the other experimental raw materials and conditions are the same, as shown in the table 1, the flame retardant grades of the polyethylene flame retardant composite materials of the comparative examples 1 and 2 are both V2 grades, while the flame retardant grades of the polyethylene flame retardant composite materials of the example 1 are both V0 grades, which indicates that the polyethylene composite materials with the reactive phosphaphenanthrene and the reactive polyphosphazene added separately have poor flame retardant effect because only the gas phase or the condensed flame retardant phase is mainly condensed in the polyethylene composite materials, in the embodiment 1, the reactive phosphaphenanthrene and the reactive polyphosphazene are added, so that the polyethylene flame-retardant composite material has gas-phase and condensed-phase double-base synergistic flame retardance and excellent nitrogen-phosphorus-sulfur synergistic flame retardance, and the polyethylene flame-retardant composite material in the embodiment 1 has excellent flame retardance. In addition, example 2 is different from the polyethylene flame retardant composite of comparative example 1 and comparative example 2 in that: the dosage of the reactive phosphaphenanthrene flame retardant in example 2 is 2kg, the dosage of the reactive polyphosphazene is 2kg, and the sum of the flame retardants is 4kg, while the raw material formula in the comparative example 1 only adds 5kg of reactive phosphaphenanthrene, the raw material formula in the comparative example 2 only adds 5kg of reactive polyphosphazene, the rest of the experimental raw materials and conditions are the same, the flame retardant grade of the polyethylene flame retardant composite material of 4kg and the flame retardant grade of the flame retardant in the example 2 are V0 grades, while the flame retardant rating of the polyethylene flame retardant composite material of comparative example 1 and comparative example 2 with a flame retardant amount of 5kg was only V2 rating, the reaction type phosphaphenanthrene and the reaction type polyphosphazene have excellent double-base synergistic effect and nitrogen phosphorus sulfur triple-element synergistic flame retardant effect, thus, the polyethylene flame-retardant composite material with lower content of reactive phosphaphenanthrene and reactive polyphosphazene can be added to obtain excellent flame-retardant property.
