Abstract

The invention belongs to the technical field of a foaming thin film, and particularly relates to a functional TPU (thermoplastic polyurethane) foaming thin film. The functional TPU foaming thin film is prepared from the following raw materials in percentage by mass: 40-80% of water, 10-20% of 1, 4-cyclohexane diisocyanate, 5-35% of polyethyleneglycol adipate glycol, 2-5% of chain extender 1, 4-butanediol, 1-5% of a halogen-free flame retardant, 0.001-0.1% of a catalyst, 0.1-1% of a foam stabilizer and 0.2-0.8% of an antioxidant. Compared with the prior art, the functional TPU foaming thin film has the advantages that as water is used as a foaming agent, the environment damage caused by using fluorine-containing foaming agents such as HCFC-141b is effectively avoided; the flame retardant property of TPU foamed plastics is improved by adding the halogen-free flame retardant, and as the flame retardant in use does not contain halogens and heavy metal elements such as lead, cadmium, mercury and chromium, the functional TPU foaming thin film is in line with European Union VDE (Verband Deutscher Elektrotechniker) requirements and is an environment-friendly material.

Description

technical field [0001] The invention belongs to the technical field of foamed films, in particular to a TPU functional foamed film. Background technique [0002] TPU (thermoplastic polyurethane) is an environmentally friendly polymer. It overcomes many defects of PVC and PU leather. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties, so it is also called TPU. Future material. It is a mature environmentally friendly material, which has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and weather resistance that other plastics and natural materials cannot match. Waterproof, moisture permeability, windproof, coldproof, antibacterial, mildewproof, warm, anti-ultraviolet and energy release and many other excellent functions. [0003] After TPU is foamed, it can be used to make home appliances s...
