Example Embodiment
[0037] Example 1
[0038] A high-impact, high-rigidity, low-odor, low-linearity polypropylene whisker modified material, which is made of raw materials including the following parts by weight: impact copolymer polypropylene 1 30.0, impact copolymer polypropylene 2 10.0 , Homopolymer polypropylene 20.0, toughening agent 1 (SEBS) 3.0, toughening agent 2 (ethylene-octene copolymer) 7.0, whiskers (whisker masterbatch) 20.0, nucleating agent 1 (HPN20E) 0.2, into Core agent 2 (TMB-5) 0.2, odor adsorbent 2.0, antioxidant 1010 0.3, antioxidant 168 0.3.
[0039] The preparation method of the high impact, high stiffness, low odor, low linearity polypropylene whisker modified material includes the following steps:
[0040] (1) Weigh polypropylene, whiskers, toughening agent, nucleating agent, odor adsorbent, main antioxidant and auxiliary antioxidant, and mix them in a high-speed mixer at high speed for 1-3 minutes, and mix well. Get the premix.
[0041] (2) Add the premix into the main feed p...
