The invention discloses a zero-defect load wave-absorbing material and a preparation method thereof, and belongs to the field of electromagnetic wave absorbing materials. The method comprises the following steps: mixing a wave absorbing agent and an adhesive, and fully stirring to obtain high-viscosity electromagnetic slurry; a forming mold is filled with the high-viscosity electromagnetic slurry, a three-dimensional vibration table is adopted for eliminating internal defects of the slurry, then the slurry is placed in a vacuum oven for secondary defect elimination, finally, the treated slurry is cured and formed in the mold, and the zero-defect load wave-absorbing material is obtained. The defects in the slurry are eliminated in a vibration and vacuum mode, and the zero-defect load wave-absorbing material is prepared.

The application provides a material premixing device for color masterbatch production, and relates to the technical field of color masterbatch production.The material premixing device comprises a mixing cylinder, a stirring assembly is arranged at the middle part of the inner side of the mixing cylinder, the stirring assembly comprises a rotating shaft, the rotating shaft is driven by a motor, a spiral conveying blade is arranged at the bottom of the rotating shaft, scraping plates are arranged at the middle parts of the two ends of the rotating shaft, rubber scraping strips are arranged at the outer sides of the scraping plates, and the rubber scraping strips are in contact with the inner wall of the mixing cylinder; a discharging assembly is arranged at the upper end of the inner side of the mixing cylinder, the discharging assembly comprises a discharging hopper, a conveying pipe is arranged at the bottom of the discharging hopper, a fixing ring is arranged at the bottom periphery of the conveying pipe, a rotating disc is connected to the top of the rotating shaft, and the fixing ring is fixedly arranged at the middle part of the side end of the rotating disc.The rotating shaft synchronously drives the stirring assembly and the discharging assembly to rotate, thereby effectively enhancing the uniformity of the discharging of raw materials, and the efficiency and quality of the premixing of color masterbatch raw materials are enhanced.
