Tpu high and low temperature film with optical color effect and preparation method thereof

Abstract

A TPU high and low temperature film with optical color effect and a preparation method thereof are provided. The TPU high-temperature film includes an optical coating layer, a texture layer, a TPU carrier layer, and a hot melt adhesive layer from top to bottom. The texture layer is made of polyurethane UV adhesive coating. The TPU high and low temperature film of the present disclosure has stable quality, excellent tensile properties, UV aging resistance, hydrolysis resistance, and boiling resistance. At the same time, its optical coating layer also has good adhesion, hydrolysis resistance, boiling resistance, and aging resistance, rendering it easy to use. The preparation method of the TPU high and low temperature film is simple in process, easy to control in operation, and conducive to industrial production. Moreover, during the production process, no waste, wastewater, exhaust gas, etc. are generated, which does not pollute the environment.
