Abstract

This invention relates to antistatic biaxially oriented polypropylene (BOPP) combination, using polypropylene as material and including opening agent, smoothness agent, antistatic agent, antioxidant, processing and heat stabilizer, wherein the antistatic agent is glycerin fatty acid ester or two ester, polyethylene glycol ester, amides and/or ethyl amines, the anti-adhesion agent is a series of silicon dioxide inorganic matters or crosslinked polysiloxane particles, the opening agent is the synthesized silicon dioxide or silicates, calcium stearate, the smoothness agent is oleic acid amide, erucic acid amide and/or silicone, and the primary and secondary antioxidants are phosphite stabilizing agent and hindered amine antioxidant. The preparation method includes adding antistatic agent, etc. additives in granulation part, and adding them into PP, mixing, and melting and granulating to obtain the BOPP antistatic resin, or pre-preparing antistatic anti-adhesion smoothness masterbatch by various components. This invention keeps the original performances of BOPP with a lower volume of auxiliaries, and obtain good performances of antistatic property, anti-adhesion, and smoothness.

Description

technical field [0001] The invention relates to a plastic composition, in particular to an antistatic biaxially stretched polypropylene (BOPP) composition and a preparation method of the antistatic biaxially stretched polypropylene composition. Background technique [0002] Biaxially oriented polypropylene (PP) film has the advantages of light weight, non-toxic, odorless, moisture-proof, high mechanical strength, good dimensional stability, and good printability. It is widely used in the field of packaging, especially in food packaging, and has the reputation of "Packaging Queen". With the development of our country's economy, many domestic manufacturers have successively introduced BOPP production lines, and the production enterprises have spread all over the country. During the production process of the film, due to the high-speed rolling or friction between the film and the traction nip roller, guide roller, tension roller, baffle, etc., the surface of the film is charge...
