摘要：To explode epoxy processing methods and overcome limitations of shear mixing and ultrasonication, internal mixer containing laminated kneading block structured rotors are designed and then the unites assemble configuration is optimized by evaluating mixing parameters of epoxy mixing field with the help of POLYFLOW software. Moreover, tip ultrasonication horn is integrated into the sealed barrel positioning at confluence areas between couple rotors to apply ultrasonication field simultaneousLy during mixing. Kinds of multi-wall carbon nanotubes are mixed with epoxy to prepare reinforced composite. Series characterizations are performed, including SEM, TGAIDSC, tensile test and thermal conductivity measurements to verif' the equipment's mixing capability. At 1.5wt% loading rate, significant mechanical improvements (above 27%) and thermal conductivity increase (above 22%) are observed, indicating excellent nanotubes dispersion and distribution in epoxy matrix.
