Abstract

The invention provides a colour master batch for a TPU film. The colour master batch is mainly prepared from the following raw materials in parts by weight: 10-20 parts of TPU, 10-20 parts of nylon 6, 30-70 parts of pigments, 2-10 parts of a dispersant, 1-5 parts of a thermal stabilizer, 5-50 parts of fillers, 1-5 parts of a compatilizer and 1-5 parts of a lubricant. The dispersion uniformity of the colour master batch provided by the invention is improved by virtue of the matching action of the TPU and the nylon 6and the matching of other various components with specific contents, and the colour master batch is stable in colour, not liable to fade, and free from a chromatic aberration phenomenon.

Description

technical field [0001] The invention belongs to the technical field of color masterbatch, and relates to a color masterbatch for TPU film and a preparation method thereof. Background technique [0002] TPU (Thermoplastic polyurethanes) is called thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type. It has a wide range of hardness (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity. It is used in daily necessities, Sporting goods, toys and decorative materials are widely used, and halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields. [0003] With the development trend of individuation and differentiation of TPU products, it is developing in the direction of diversification and bright colors, and the requirements for coloring are also increasing. [0004] At present, when using TPU color masterbatch to color TPU, comm...
