PET antibacterial antistatic smooth master batch and preparation method thereof

Abstract

The invention discloses a PET antibacterial antistatic smooth master batch and a preparation method thereof. The PET antibacterial antistatic smooth master batch comprises, by mass, 30 to 70% of a carrier, 10 to 30% of a smoothing agent, 5 to 15% of an opening agent, 10 to 20% of an antistatic agent, 5 to 10% of an antibacterial agent, 1 to 3% of a dispersant, 0.5 to 2% of a coupling agent and 0 to 1% of other additives. The invention has the following beneficial effects compared with the prior art: when applied in PET films or laminates, the PET antibacterial antistatic smooth master batch has good anti-blocking and smoothing effects, long-lasting and stable antibacterial performance, excellent anti-static performance and good mechanical strength, enables a smooth and flat surface to be obtained, is simple to operate and convenient to use, better improves product performance, processing environment and the like and has wide application prospects.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a PET antibacterial and antistatic smooth masterbatch and a preparation method thereof. Background technique

[0002] Polyethylene terephthalate (PET) is a crystalline polymer widely used in Packaging films for cosmetics, food, electronics, toys, printing and other industries, but the smoothness of polyethylene terephthalate alone is relatively poor, and the antistatic effect is not good. At the same time, with the improvement of people's living standards, the demand for antibacterial PET is also increasing. Adding an appropriate amount of antibacterial agent can endow PET with a certain antibacterial and bactericidal ability, but the disadvantage is that the antibacterial performance is poor in durability, and it may also lead to the production process. Heat reaction will cause the product to turn yellow, change color, etc. Contents of the invention
