[0041] The embodiment of the present invention further provides a method for preparing a plastic alloy, comprising the following steps:
[0042]S01, surface-treating kaolin with a surface treatment agent to obtain activated kaolin;
[0043] S02, mix PP resin, PPO resin and compatibilizer, stir, dehumidify when the temperature reaches 75-85°C, add the activated kaolin, stir to obtain a premix, extrude and granulate to obtain a plastic alloy material.
[0044] Specifically, in step S01, the surface treatment agent and kaolin are the same as before, and will not be repeated here. Step S01 is specifically:
[0045] Stir the kaolin, dehumidify when the temperature reaches 70°C-85°C, add a surface treatment agent when the temperature reaches 115°C-155°C, stir for 3-8 minutes to obtain an activated kaolin precursor, cool to obtain activated kaolin. The cooling step is specifically carried out by putting the activated kaolin precursor into a cold mixer and cooling to 40-55° C. to ob...

[0054] The method for preparing a plastic alloy according to the embodiment of the present invention comprises the following steps:
[0055] (1) Preparation of 6000 mesh activated kaolin
[0056] Put 10 parts by weight of 6000-mesh activated kaolin powder into a high-speed mixer and stir at a high speed. When the temperature reaches 70°C, dehumidification starts. When the temperature reaches 115°C, add 0.5 parts by weight of silane coupling agent and mix for 3 minutes. , and then put the mixture in the high mixer into the cold mixer for cooling, and then discharge the material after cooling to 40°C to obtain surface-treated 6000-mesh activated kaolin;
[0057] (2) Preparation of 6000 mesh active kaolin filled modified PP / PPO alloy material premix
[0058] Put 37.2 parts by weight of PP, 16 parts by weight of PPO resin, 17 parts by weight of maleic anhydride, 7.5 parts by weight of bromotriazine and 7.5 parts by weight of antimony trioxide into a high mixer Mix and stir, and ...
Embodiment 2
[0062] The method for preparing a plastic alloy according to the embodiment of the present invention comprises the following steps:
[0063] (1) Preparation of 4000 mesh activated kaolin
[0064] Put 15 parts by weight of 4000 mesh activated kaolin powder into a high-speed mixer and stir at a high speed. When the temperature reaches 75°C, dehumidification starts. When the temperature reaches 120°C, add 0.5 parts by weight of titanate coupling agent and mix and stir 4 minutes, then put the mixed material in the high mixer into the cold mixer for cooling, and discharge after cooling to 45°C to obtain surface-treated 4000-mesh activated kaolin;
[0065] (2) Preparation of 4000 mesh active kaolin filled modified PP / PPO alloy material premix
[0066] Put the PP of 32.2 parts by weight, the PPO resin of 16 parts by weight, the polypropylene graft maleic anhydride of 17 parts by weight, the bromotriazine of 9 parts by weight and the antimony trioxide of 6 parts by weight Mix and st...
