Abstract

The invention provides a temperature-resistant TPU film for automotive interior decoration, and a preparation method thereof. The TPU film comprises raw material components with the following parts bymass: 50-70 parts of TPU particles, 20-30 parts of epoxy resin, 10-20 parts of melamine resin, 5-10 parts of porous ceramic particles, and 3-8 parts of an epoxy silane coupling agent. The TPU film isprepared through the following steps: the porous ceramic particles are alcoholized and acidized; the alcoholized and acidized particles react with the epoxy silane coupling agent and the melamine resin to form melamine resin coated porous ceramic particles; and melt blending is carried out on the melamine resin coated porous ceramic particles, the TPU particles and the epoxy resin. The TPU film provided by the invention achieves a higher mechanical strength, better temperature-resistant performance and a smooth surface, so as to be used as an automotive interior decoration material.

Description

technical field [0001] The invention belongs to the technical field of TPU films, and in particular relates to a temperature-resistant TPU film for automobile interior decoration and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer (TPU) is a block material with both plastic thermoplasticity and mechanical strength and rubber elasticity. Because of its excellent low temperature resistance, abrasion resistance and chemical corrosion resistance, it is used in various industries The application in the industry is expanding rapidly. Due to the diversity of raw materials and the adjustability of molecular structure, thermoplastic polyurethane is widely used in industries such as elastomers, foam plastics, coatings, and adhesives. However, TPU has poor heat resistance, and its short-term use temperature does not exceed 120°C, and its long-term use temperature does not exceed 80°C, which limits its use in a certain temperature range....
