Abstract

The invention discloses a TPU film. The TPU film comprises, by weight, 90-110 parts of TPU, 0.5-2.0 parts of an antioxidant, 0.5-3.0 parts of special effect powder and 0.5-1.0 part of a processing aid. The special effect powder comprises one of metal powder, pearl powder, organic powder and inorganic powder. The special effect powder and TPU are molten and mixed to form a film. The film does not fade.

Description

Technical field: [0001] The invention relates to the technical field of TPU, in particular to a TPU film and a preparation method thereof. Background technique: [0002] With the gradual improvement of people's living standards, the requirements for daily necessities or products are getting higher and higher, and they like to have aesthetic effects on the used items, such as bright and colorful tones and pearlescent, flashing effects, metallic luster and texture, etc. Special effect. In the prior art, special effect powders such as gold powder, silver powder and pearl powder are processed and attached to the surface of the formed film. After actual testing and inspection, the special effect powder on the surface of the film is easy to fall off due to such processing, and the effect is not good. Invention content: [0003] The object of the present invention is to provide a kind of TPU film and its preparation method, the present invention forms film directly after all raw...
