Embodiment Construction

[0016] The following table shows the formulations and viscosity tests of the examples and comparative examples. The liquid masterbatch was prepared by a three-roll mill. It can be seen from the experimental results that the viscosity of Examples 1 and 2 is higher than that of the comparative example, which is beneficial to long-term storage and ease of pumping.

Abstract

The invention discloses a coloring master batch used for polyester, which is composed of the following components with the weight percentage: polyol ester carrier 20-99%, a coloring agent 0.5-80% and a function additive 0-40%. Silicon oxide is not needed to be added into the liquid master batch to adjust viscosity, and good processing performance and storage performance of the liquid master batch are achieved. The liquid coloring master batch is applied to polyester products including polyethylene terephthalate (PET), polybutylece terephthalate (PBT), polyethylene terephtalate glycol-modified (PETG), polythy-lene naphtalate (PEN) and the like.

Description

[0001] technical field [0002] The invention relates to the field of plastic coloring, in particular to a carrier for liquid coloring masterbatch for polyester plastics. Background technique [0003] Polyester resins (PET, PETG, PBT, PEN, etc.) are widely used in packaging, electronic appliances, medical and health, construction, automobiles, textiles and other fields. [0004] Polyester coloring includes toner coloring, granular color masterbatch coloring, and liquid color masterbatch coloring. Compared with toner coloring, liquid color masterbatch has no dust pollution, and has better dispersibility than granular color masterbatch coloring, especially transparent color. Liquid color masterbatch coloring has no flow lines and black spots, and is more favored by users. At present, liquid masterbatch coloring is widely used in polyester coloring, especially light-colored polyester coloring. The existing liquid color masterbatch mostly uses the mixture of sorbitan monooleat...
