Embodiment 1
[0020] Crush the rubber to 100 mesh, mix it with the crushed rice straw, then add it into the KOH solution with a mass percentage of 18%, soak it for 45 minutes at a temperature of 92°C, wash the reacted sediment with water until it is neutral, and then dry it to obtain Mixed sediments; wherein, the mass ratio of rubber to rice straw is 1:1.5; adding hydrochloric acid to the mixed sediments, and carrying out airtight stirring for 2 hours, during the stirring process, the pH value is 1-3, and the stirring temperature is 40°C. After the reaction, the mixed sediment was washed with water at a water temperature of 40°C until it was neutral, and then dried to obtain the second sediment; the second sediment was immersed in the mixed solution, stirred thoroughly and left to stand for 20 minutes, and then titanium dioxide and aluminum oxide were added. The nanoparticles and graphite particles were subjected to ultrasonic vibration and then left to stand for 20 minutes, and then the mix...
Embodiment 2
[0022] Grinding the rubber to 80 mesh, mixing it with the crushed rice straw, then adding it into a KOH solution with a mass percentage of 22%, soaking it at a temperature of 96°C for 50 minutes, washing the reacted sediment with water until it is neutral, and then drying it to obtain Mixed sediment; wherein, the mass ratio of rubber to rice straw is 1:4; add hydrochloric acid to the mixed sediment, and carry out airtight stirring for 2 to 3 hours. During the stirring process, the pH value is 1 to 3, and the stirring temperature is 55 to 60°C, wash the reacted mixed sediment with water at a water temperature of 55-60°C until it is neutral, then dry to obtain the second sediment; immerse the second sediment in the mixed solution, stir it well and let it stand for 30 minutes, then add titanium dioxide , Al2O3 nanoparticles and graphite particles, ultrasonically oscillate and then stand still for 30 minutes, then evaporate and dry the mixture deposited with TiO2 and Al2O3 at 101-1...
