What are the methods for preparing PET masterbatch?

Now the application of PET masterbatch is very wide, so do you know his preparation method? How is it prepared? Next, let's take a detailed look at the preparation method of PET masterbatch.

One: Add the anti-blocking agent and coupling agent to the high-speed mixer with a rotation speed of 500 to 1500 rpm, mix for 3 to 5 minutes, and then add the carrier, slip agent, colorant, dispersant and Antioxidant, mixed at 85 ℃ ～ 100 ℃ for 5-30 minutes;

Two: Weigh each component according to the weight ratio to be ready for use;

Three: Add the above mixed materials to the twin-screw extruder to fully melt and blend, the melting temperature is controlled at 255 ℃ ~ 270 ℃, the screw speed is 100 ~ 300 rpm, through the twin screw extruder shear, Knead for 10 to 15 minutes, and then granulate and dry to obtain PET masterbatch.
