Example Embodiment
[0033] Example 1
[0034] The special material for biaxially oriented polypropylene BOPP is used as the matrix resin, the antistatic agent is a combination of glyceride and hydroxyethyl alkylamine (1:1), and superfine SiO 2 The particles are grinding agents, stearic acid amide is used as dispersant, 1010 and 168 (1:1) are used as antioxidants, the inhibitor is an amine inhibitor, and 770 is used as an antioxidant.
[0035] raw material name
[0036] Put all the raw materials into a high-mixer and mix for 4 minutes, discharge them, and then extrude and pelletize them with a screw extruder. The processing temperature is 200°C and the screw rotation speed is 450 rpm to prepare BOPP high-efficiency antistatic masterbatch. grain.
Example Embodiment
[0037] Example 2
[0038] Take BOPP as matrix resin, antistatic agent is a combination of saturated partially esterified glyceride and hydroxyethyl alkylamine (1:1), and superfine SiO 2 The particle is a grinding agent, stearic acid amide is used as a dispersant, 1010 and 168 (1:1) are used as an antioxidant, the inhibitor is an amine inhibitor, and a hindered amine light stabilizer 770 / 944 ( 1:1) is an antioxidant.
[0039] raw material name
[0040] With the same processing technology as in Example 1, a high-efficiency antistatic masterbatch for biaxially oriented polypropylene was prepared.
