▎ 摘　　要

NOVELTY - Capacitor filling complex material comprises 50-70 wt.% paraffin wax, 5-15 wt.% spinel metal oxide powder, 5-15 wt.% graphene powder, and 2-5 wt.% nickel powder. USE - Used as capacitor filling complex material. Can also be used in power system and electrical device. ADVANTAGE - The capacitor filling complex material has high shielding effect, improves microwave absorption performance, reduces the temperature of the capacitor core, prolongs the service life of the capacitor, and reduces working noise of the capacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing capacitor filling complex material comprising (i) mixing the graphene powder and nickel powder uniformly, placing them into a sealed grinding jar and grinding for 2 hours, (ii) mixing the material with spinel metal oxide powder, placing into a sealed grinding tank and grinding for 4 hours, (iii) placing paraffin wax into the heating pot, heating and liquefying the paraffin wax, and controlling the temperature within 80-100℃, and (iv) gradually adding the material into the heating pot, placing the shear dispersion instrument in the heating pot, adjusting the rotating speed at 1500 parts per million/second, heating and shearing for 1 hour, and then adjusting the rotating speed at 3000 parts per million/second, heating and shearing for 1 hour, and then emulsifying for 1 hour with an ultrasonic dispersing emulsifying machine to form a black paste, stop heating, taking out, introducing into a mold for cooling and molding to obtain a complex material.
