Embodiment 1
[0022] A. Add 5 parts of red phosphorus into a ball mill to refine it to 1000 mesh, and dry it at 50°C for 10 hours to obtain pretreated red phosphorus;
[0023] B, 1 part of zinc sulfate, 1 part of borax, 1 part of zinc oxide and 1 part of hydroquinone are added in the reactor that fills distilled water, after dissolving completely, add the pretreatment red phosphorus that obtains in step A, and at 90 Under the condition of ℃, use a magnetic stirrer to stir and react for 7 hours, and finally filter, wash and dry to obtain inorganic-coated red phosphorus;
[0024] C. Mix 1 part of phenolic resin with 5 parts of ethanol, then add the inorganic-coated red phosphorus obtained in step B and 30 parts of PP and 40 parts of PE to obtain a mixture;
[0025] D. Add the mixture obtained in step C to a screw extruder for plasticization, melting, extrusion and granulation to obtain a PP-PE alloy material.
Embodiment 2
[0027] A. Add 8 parts of red phosphorus to a ball mill to refine it to 1100 mesh, and dry it at 55°C for 13 hours to obtain pretreated red phosphorus;
[0028] B, 3 parts of zinc sulfate, 3 parts of borax, 2 parts of zinc oxide and 3 parts of hydroquinone are added in the reactor that fills distilled water, after dissolving completely, add the pretreatment red phosphorus that obtains in the step A, and at 95 Under the condition of ℃, use a magnetic stirrer to stir and react for 9 hours, and finally filter, wash and dry to obtain inorganic-coated red phosphorus;
[0029] C. Mix 3 parts of phenolic resin with 8 parts of ethanol, then add the inorganic-coated red phosphorus obtained in step B and 35 parts of PP and 45 parts of PE to obtain a mixture;
[0030] D. Add the mixture obtained in step C to a screw extruder for plasticization, melting, extrusion and granulation to obtain a PP-PE alloy material.
Embodiment 3
[0032] A. Add 10 parts of red phosphorus into a ball mill to refine it to 1200 mesh, and dry it at 60°C for 15 hours to obtain pretreated red phosphorus;
[0033] B, 5 parts of zinc sulfate, 5 parts of borax, 3 parts of zinc oxide and 5 parts of hydroquinone are added in the reactor that fills distilled water, after dissolving completely, add the pretreatment red phosphorus that obtains in step A, and in 100 Under the condition of ℃, use a magnetic stirrer to stir and react for 10h, and finally filter, wash and dry to obtain inorganic-coated red phosphorus;
[0034] C. Mix 5 parts of phenolic resin with 10 parts of ethanol, then add the inorganic coated red phosphorus obtained in step B and 40 parts of PP and 50 parts of PE to obtain a mixture;
[0035] D. Add the mixture obtained in step C to a screw extruder for plasticization, melting, extrusion and granulation to obtain a PP-PE alloy material.
