Problems solved by technology

[0004] The above-mentioned patent uses silicon dioxide as an anti-blocking agent, which cannot effectively act on the surface of the product. It needs to increase the amount of addition to have a significant effect, but increasing the content will reduce the transparency of the material and even affect the mechanical properties of the material.

Abstract

The invention discloses a PET color master batch and a preparation method thereof, and relates to the technical field of plastic master batches. The PET color master batch comprises the following components in parts by mass: 70-90 parts of PET (polyethylene terephthalate); 10-20 parts of pentaerythritol tetrastearate; 10-20 parts of IncroMax 100 slipping agent; 1-3 parts of a dispersing agent and2-4 parts of an antistatic agent. The PET color master batch has the advantages of reducing friction force on the surface of a material and resisting static electricity.

Description

technical field [0001] The invention relates to the field of plastic master batches, more specifically, it relates to a PET color master batch and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a crystalline polymer widely used in Packaging films or sheets for cosmetics, food, electronics, toys, printing and other industries. The polyester film or sheet made of it has good toughness, mechanical strength and excellent transparency, but its slipperiness is relatively poor, which brings inconvenience to use. [0003] In the Chinese invention patent whose publication number is CN103881330A, a PET anti-blocking smooth masterbatch and a preparation method thereof are disclosed. The PET anti-blocking and slippery masterbatch of the present invention has the following components by mass percentage: PET carrier 50%-90%, anti-blocking agent 5%-15%, slippery agent 10%-25%, dispersant 1 %~3%, coupling agent 0.5%~2%, antioxidant 0.1%~1%...
