Description

Technical Field

[0001] The invention belongs to the field of masterbatch preparation, and in particular relates to an anti-adhesion preparation device and a method for preparing PBT masterbatch. Background Art

[0002] Polybutylene terephthalate (PBT) is a crystalline thermoplastic polyester resin. Due to its excellent comprehensive performance, it is widely used in electronic appliances, automotive industry, building materials, mechanical parts, packaging and other fields. It is collectively known as the five major general-purpose engineering plastics with PPS, PC, POM, PA, etc. Usually, PBT products need to be matched with colors, and its coloring methods can be divided into three types: coloring with toner, coloring with pellets and coloring with masterbatches. Coloring with toner is very simple, but it has the disadvantages of easy color points, difficult to control color difference, and greater environmental pollution. Coloring with pellets is to mix the pigment into the plastic raw material. Each plastic material has been colored, so the color of the product is stable and uniform, but it damages the mechanical properties of the product to a certain extent, and the cost is high, and a large amount of colored raw materials need to be stored. Masterbatch coloring is to uniformly load the pigment in the resin in an extraordinary amount, thereby greatly improving the dispersion performance and coloring efficiency of the pigment. It has the advantages of simple operation, low cost and no pollution to the environment.
