Embodiment 1
[0026] First, add 45 parts by weight of waste rubber to the pulverizer for pulverization, then transfer the pulverized material to a desulfurization kettle for high-temperature desulfurization, and filter it, and then transfer the filtered material to a kneader for kneading and stirring , the stirring speed is 50 revolutions / s;
[0027] Next, in the kneader after the aforementioned stirring, adding parts by weight is 40 parts of modified graphene nanofillers, 23 parts of N-isopropylmaleimide-methyl methacrylate, tetrafluoroethylene-perfluoroalkyl 31 parts of vinyl ether copolymerized fibers, 22 parts of polymethyl methacrylate, continue to stir for 2 hours, and then add 9 parts by weight of isobutylene, 8 parts by weight of white carbon black and 4 parts by weight of carbon black in the kneader. Black, after kneading and stirring for 5.5 hours, the material was transferred to the stirring device; and the stirring speed was 50 rpm / s;
[0028] Add 46 parts by weight of iron pow...

[0031] First, add 45 parts by weight of waste rubber to the pulverizer for pulverization, then transfer the pulverized material to a desulfurization kettle for high-temperature desulfurization, and filter it, and then transfer the filtered material to a kneader for kneading and stirring , the stirring speed is 49 revolutions / s;
[0032] Next, in the kneader after the aforementioned stirring, adding parts by weight is 40 parts of modified graphene nanofillers, 23 parts of N-isopropylmaleimide-methyl methacrylate, tetrafluoroethylene-perfluoroalkyl 31 parts of vinyl ether copolymerized fibers, 22 parts of polymethyl methacrylate, continue to stir for 1 hour, then add 9 parts by weight of isobutylene, 8 parts by weight of white carbon black and 4 parts by weight of carbon black in the kneader. Black, after kneading and stirring for 6 hours, the material was transferred to the stirring device; and the stirring speed was 49 rpm / s;
[0033] Add 46 parts by weight of iron powder, 46...
Embodiment 3
[0036] First, add 45 parts by weight of waste rubber to the pulverizer for pulverization, then transfer the pulverized material to a desulfurization kettle for high-temperature desulfurization, and filter it, and then transfer the filtered material to a kneader for kneading and stirring , the stirring speed is 48 rpm / s;
[0037] Next in the kneader after the aforementioned stirring, add the modified graphene nano-filler that the weight part is 40 parts, continue to stir for 2 hours, add the isobutylene that the weight part is 9, the white carbon black that the weight part is 8 in the kneader again in the kneader and The carbon black of 4 parts by weight, after kneading and stirring for 5 hours, the material is transferred to the stirring device; and the stirring speed is 48 revolutions / s;
[0038]Add 46 parts by weight of iron powder, 46 parts by weight of aluminum powder, 1.0 part by weight of antifungal agent and 5 parts by weight of pottery clay to the stirring device again...
