Abstract

The invention discloses PBT high density color master batch and a preparation method thereof. The PBT high density color master batch is prepared from the following components by mass percent: 70-90% of pigment, 10-20% of PBT resin, 3-5% of dispersant, 0.1-1% of anti-oxidant, and 0.1-1% of antistatic agent. Compared with the prior art, the beneficial effects reside in that: when used for coloring a PBT product, the color master batch provided by the invention has characteristics of good dispersibility, uniform coloring, high concentration, small usage amount and no influence on mechanical properties of the PBT product, and also has advantages of low cost, simple process, easy coloring, convenient usage and time and raw material saving.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PBT high-concentration color masterbatch and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is a crystalline thermoplastic polyester resin, which is widely used in electronic appliances, automobile industry, building materials, mechanical parts, packaging and other fields due to its excellent comprehensive properties. And together with PPS, PC, POM, PA, etc., they are called the five general-purpose engineering plastics. Usually, PBT products need to be matched with colors, and the coloring methods can be divided into three types: toner coloring, dyeing granule coloring and masterbatch coloring. Toner coloring is very simple, but it has the disadvantages that it is easy to produce color spots, the color difference is not easy to control, and it has great environmental pollution. Dyeing and granulation Coloring is to mix ...
