USE - Low-noise power distribution box shell for electric power (claimed). ADVANTAGE - The low-noise power distribution box shell has high abrasion resistance, good impact resistance, good elasticity, strength, shock absorption and noise reduction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing low-noise power distribution box shell, which involves: (A) adding molybdenum disulfide into N-methyl pyrrolidone and molybdenum disulfide suspension in ratio of 1-15:10g/ml to obtain mixture; (B) subjecting the mixture to ultrasonic peeling for 1-5 hours; (C) preheating mixer at 70-80 degrees C, and adding with acrylic resin, styrene butadiene rubber, chloroprene rubber, fluoroether rubber and phenolic resin under mixing 22-24 minutes to obtain rubber base material; (D) cooling the rubber base material at 30-35 degrees C, and adding with obtained mixture to obtain mixture A; (E) adding the mixture A to reflux device, and mixing with cyclohexane under stirring and refluxing for 30-40 minutes to obtain mixture; (F) filtering the mixture to obtain solid mixture; (G) drying the solid mixture by hot nitrogen, and transferring into reaction kettle; (H) adding the obtained reaction kettle with silicon carbide, graphene, semi-reinforcing furnace black, calcined clay and carbon black under heating at 50-60 degrees C under inert gas atmosphere for 120-150 minutes to obtain intermediate; (I) adding the intermediate with antioxidant, zinc oxide and accelerator, and transferring to rubber-making machine under mixing at 90-100 degrees C for 20-30 minutes to obtain mixture; (J) adding the mixture into vulcanizing machine to obtain vulcanized material; (K) adding the vulcanized material into mold cavity, and hot-pressing at 150-170 degrees C at 280-300 megapascals pressure; and (L) heat-curing the obtained mold for 30-35 minutes to obtain the desired product.
