Embodiment 1

[0034] Biaxially oriented polypropylene BOPP special material is used as the matrix resin, the antistatic agent is a composition of glyceride and hydroxyethyl alkylamine (1:1), and ultrafine SiO 2 The particle is grinding agent, stearic acid amide is used as dispersant, the compound of 1010 and 168 (1:1) is used as antioxidant, inhibitor is amine inhibitor, and 770 is used as antiaging agent.

[0035] raw material name

[0036] Put all the raw materials into the high-mixer and mix for 4 minutes, discharge the material, and then use a screw extruder to extrude and granulate. The processing temperature is 200 ° C, and the screw rotation speed is 450 rpm to obtain a high-efficiency antistatic masterbatch for BOPP. grain.

Embodiment 2

[0038] With BOPP as the matrix resin, the antistatic agent is a composition of saturated partially esterified glyceride and hydroxyethyl alkylamine (1:1), and superfine SiO 2 The particles are grinding agents, stearic acid amide is used as dispersant, the compound of 1010 and 168 (1:1) is used as antioxidant, the inhibitor is amine inhibitor, and hindered amine light stabilizer 770 / 944 ( 1:1) is an anti-aging agent.

Abstract

The invention relates to a highly effective antistatic agglomerate for biaxial tension polypropylene and its preparation method, wherein the agglomerate comprises raw materials of the following constituents (by weight proportion): polypropylene 70-90%, antistatic agent 8-30%, grinding agent 0.1-1%, dispersing agent 0.1-2%, anti-oxidant 0.1-1%, inhibiting agent 0.1-0.5%, anti-ageing 0.1-0.5%.

Description

technical field [0001] The invention relates to a high-efficiency antistatic masterbatch for biaxially stretched polypropylene and a preparation method thereof. It has long-term antistatic performance at a relatively low dosage and can be used to manufacture polypropylene film products with antistatic performance. Technical field of propylene polymer modification. technical background [0002] Biaxially oriented polypropylene (BOPP) film has the characteristics of high gloss, high stiffness, good gas barrier properties, and high impact strength. It is a high-transparency packaging material with excellent performance. Since the late 1980s, BOPP films have been widely used in the packaging of food, beverages, cigarettes, clothing and other industries. The antistatic effect of existing BOPP is not long-lasting. After adding antistatic agent, the film-forming properties are poor, the dispersion is not good, there are many defects, and it is easy to age, the film becomes red, an...
