Problems solved by technology

At present, the moisture permeability rate of products produced by TPU materials is low. In hot weather, the sweat emitted by the human body cannot be quickly discharged to give the skin a dry and comfortable feeling. In rainy weather, it cannot prevent rainwater from entering the clothing to protect it. function, thus having to be tied to the weather while exercising

Abstract

The invention discloses a TPU film with a good moisture permeation rate as well as a manufacturing method and application of the TPU film. The TPU film contains the following materials: perfluoropolyether diol, a chain extender, aliphatic diisocyanate, TPO resin, master batches, an antioxidant, a light stabilizer, an anti-yellowing agent, erucamide, oleamide and stearic acid. The preparation method of the TPU film comprises the following steps: (1) preparing fluorine-containing TPU; (2) uniformly stirring fluorine-containing TPU with the TPO resin, the master batches, the antioxidant, the light stabilizer, the anti-yellowing agent, erucamide, oleamide and stearic acid; and (3) adding the material obtained in the step (2) into an internal mixer, carrying out internal mixing for 5-10 minutes, and extruding by virtue of an extruder. The TPU film is used as a fabric of garments and shoes. The TPU film utilizing the technical scheme has a good moisture permeation rate and excellent water tolerance, and a product is safe, environment-friendly and comfortable.

Description

technical field [0001] The invention relates to a TPU film with good moisture permeability and its manufacturing method and application, belonging to the technical field of TPU material application. 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 widely used in daily necessities and sporting goods. , toys, decorative materials and other fields are widely used, halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields. The so-called elastomer refers to a polymer material with a glass transition temperature lower than room temperature, an elongation at break > 50%, and better recovery after external force is removed. Polyurethane elastomers are a rela...
