PVC resin, 10-15 pts. wt. anti-aging agent, 10-15 pts. wt. talc powder, 10-15 pts. wt. kaolin powder, 1-5 pts. wt. paraffin wax, 15-20 pts. wt. dibutyl phthalate. The anti-aging agent is made by adding cyanuric chloride, chlorobenzene, and aluminum chloride into the reaction kettle at a speed of 100-120r/min and a temperature of 3-5 degrees C, stirring until it is mixed, adding magnesium powder, continue to stir for 20-30 minutes, adding m-nitrophenol, the addition time is 1.5-2h. After continuing the reaction for 2-4 hours, the temperature is raised to 25-30 degrees C, and after stirring for 10-15 hours, resorcinol is added, at a temperature of 80-90 degrees C, after reacting for 5-8h, at a temperature of 150 degrees C, after distilling to remove chlorobenzene, temperature is lowered, and the filtrate is removed by filtration under the condition of 50-55 degrees C, and the filter cake is dried to obtain Intermediate 1. USE - Corrosion-resistant battery casing. ADVANTAGE - The corrosion-resistant battery casing has increased service life, and the corrosion-resistant carrier uses polyaniline and graphene as raw materials, so that the corrosion resistance of the battery casing is further improved. DETAILED DESCRIPTION - Corrosion-resistant battery casing comprises 100-120 pts. wt. PVC resin, 10-15 pts. wt. anti-aging agent, 10-15 pts. wt. talc powder, 10-15 pts. wt. kaolin powder, 1-5 pts. wt. paraffin wax, 15-20 pts. wt. dibutyl phthalate. The anti-aging agent is made by adding cyanuric chloride, chlorobenzene, and aluminum chloride into the reaction kettle at a speed of 100-120r/min and a temperature of 3-5 degrees C, stirring until it is mixed, adding magnesium powder, continue to stir for 20-30 minutes, adding m-nitrophenol, the addition time is 1.5-2h. After continuing the reaction for 2-4 hours, the temperature is raised to 25-30 degrees C, and after stirring for 10-15 hours, resorcinol is added, at a temperature of 80-90 degrees C, after reacting for 5-8h, at a temperature of 150 degrees C, after distilling to remove chlorobenzene, temperature is lowered, and the filtrate is removed by filtration under the condition of 50-55 degrees C, and the filter cake is dried to obtain Intermediate 1. The intermediate 1, tin powder, and concentrated hydrochloric acid are added to the reaction kettle, under the condition of rotating speed of 150-200r/min, carrying out the reaction for 2-3 hours, adjust the pH of the reaction solution to 10 to obtain Intermediate 2. Phenol and aniline are added to the reaction kettle, after blowing in nitrogen to replace the air, adding toluene and concentrated hydrochloric acid, at a rotation speed of 200-300r/min. After stirring for 20-30 minutes, at a temperature of 120-130 degrees C, reflux reaction for 2-3 hours, cool to room temperature and add methanol. After mixing, distillation is performed at a temperature of 115 degrees C to obtain Intermediate 3. Intermediate 3 is dissolved in tetrahydrofuran, sulfur and iodine are added, and the reflux reaction is carried out at 170-175 degrees C for 3-5 hours to obtain Intermediate 4, dissolve Intermediate 4 in tetrahydrofuran, add dibromoethane, at a speed of 150-200r/min and a temperature of 40-50 degrees C. After stirring for 10-15 minutes, Intermediate 2 is added and continue to stir 1-1.5g to obtain Intermediate 5. The ethyl acetate, potassium carbonate, and Intermediate 5 are added into the reaction kettle, at a rotation speed of 100-120r/min, stirring until the mixing is uniform, add chloroacetic acid dropwise at a temperature of 60-65 degrees C for 1.5-2h, and after keeping it for 6-8h, warm up to a temperature of 100 degrees C, filter, continue to cool the filtrate to a temperature of 10-15 degrees C, filter again to remove the filtrate. The filter cake is dried to obtain Intermediate 6, and Intermediate 6, ethylenediamine, toluene, and 1-hydroxybenzotriazole are added to the reaction kettle at a temperature of 40-45 degrees C. After carrying out the reaction for 3-5 hours, the corrosion-resistant carrier is added, and after the reaction is continued for 2-3 hours, the filtrate is removed by filtration, and the filter cake is dried to prepare the anti-aging agent. An INDEPENDENT CLAIM is included for a method for preparing a corrosion-resistant battery casing, which involves weighing PVC resin, anti-aging agent, talcum powder, kaolin powder, paraffin, and dibutyl phthalate, and blending at a temperature of 80-90 degrees C to prepare a mixture, using twin-screw extruder to melt and extrude the mixture at a temperature of 150-160 degrees C, adding to a mold, and cooling to obtain a battery casing.
