Abstract

The invention discloses a high-weather-resistant TPU film and a preparation method thereof. The TPU film is prepared from the following components in parts by weight: 100 parts of polyester type TPU particles, 0.1 to 5 parts of an antioxidant, 0.1 to 5 parts of a heat resistant stabilizer, 0.1 to 1 part of an ultraviolet light absorber, and 0.1 to 1 part of a silver based antibacterial agent, wherein the heat resistant stabilizer adopts a combination of a tin stabilizer and zinc stearate. The TPU film has excellent weather resistance.

Description

technical field [0001] The invention relates to a TPU film and a preparation method thereof, in particular to a high weather resistance TPU film and a preparation method thereof. Background technique [0002] TPU (Thermoplastic polyurethanes) is called thermoplastic polyurethane elastomer rubber, which is mainly divided into polyester type and polyether type. It has a wide range of hardness (60HA-85HD), wear resistance, oil resistance, transparency, good elasticity, and is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. [0003] TPU film is a film made by special processes such as calendering, casting, film blowing and coating on the basis of TPU pellets. TPU (thermoplastic polyurethane) is increasingly popular because of its superior performance and environmental protection concept. At present, wherever PVC is used, TPU can become a substitute for PVC. However, the advantages of TPU are beyond the reach of PVC. TPU not only...
