preparation example Construction

[0041] A preparation method of a nano wave-absorbing plastic material is carried out in the following steps:

[0042] a. Weigh the required weight of the plastic masterbatch according to the weight percentage and pour it into the mixer and stir evenly for later use;

[0043] b. Preparation of nano-masterbatch: Weigh the required weight of nano-β-silicon carbide, nano-nickel powder and liquid polyaniline according to the weight percentage and pour it into another mixer, ultrasonically oscillate evenly, dry and granulate for later use;

[0044] c. Take the required weight of the prepared nano-masterbatch and plastic masterbatch according to the weight percentage and pour it into the mixer and stir evenly. The mixing weight ratio is: nano-masterbatch: plastic masterbatch=1~2.8:1.3~ 5.6;

[0045] d. Dehumidification and drying;

[0046] e. Process flow

[0047] ①, nano masterbatch + plastic masterbatch mixing;

[0048] ②, 60 ℃ ~ 65 ℃ dehumidification and drying;

[0049] ③ St...
