Abstract

The invention discloses a TPU color master batch, an anti-migration printing TPU film and a preparation method of the TPU color master batch. The TPU film is prepared from the following components: 10to 20 parts of TPU color master batch, 60 to 80 parts of TPU particles, 5 to 10 parts of slipping agent master batch and 1 to 3 parts of antioxidant, wherein the TPU color master batch comprises TPUparticles, a pigment and peroxide; the preparation method of the TPU color master batch comprises the following steps: TPU modification; internal mixing; granulation. By preparing and using the TPU color master batch without a dispersing agent, the use amount of the dispersing agent in a TPU film formula is greatly reduced, so that the migration amount of an additive on the surface of the obtainedTPU film is greatly reduced, the printing or printing definition of the TPU film is finally improved, and the printing or printing quality of the TPU film is improved.

Description

technical field [0001] The invention relates to the field of TPU films, in particular to a TPU color masterbatch, an anti-migration printing TPU film and a preparation method thereof. Background technique [0002] TPU (Thermoplastic polyyrethane, thermoplastic polyurethane) is a new type of organic polymer synthetic material. The English trade name is: Flexible polyurethane. It has many expandable functions and good performance, so it has broad application prospects. Polyurethane elastomer is a material with strong cohesive energy and excellent wear resistance. Compared with natural rubber, its wear resistance can be increased by 2-10 times. At the same time, it also has high mechanical strength and tear strength, coupled with its excellent shock absorption and buffer performance, it has a better ability to "overcome rigidity with softness". [0003] TPU film is often used in the printing field. However, when the existing TPU film is printed or printed, due to the process...
