Abstract

The flame-retardant TPU composite fabric comprises base cloth, a TPU film and a warm-keeping layer, the TPU film and the warm-keeping layer are attached to the two sides of the base cloth through adhesive layers respectively, the TPU film is prepared from TPU master batch through a film blowing machine, and the TPU master batch is prepared from the following raw materials: polyether type TPU , polyester type TPU, polyisophthaloyl metaphenylene diamine fibers, aluminum diisoxyacetoacetate, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, polydimethylsiloxane, zinc pyrithione, dioleamide, an antioxidant and a light stabilizer. According to the invention, the temperature resistance grade of the TPU film is improved, the temperature conduction time is delayed, the heat conductivity coefficientof the TPU film is reduced to 0.180.27 W / mk, the oxygen index is improved to 28.6-32.5%, after combustion, the higher oxygen index and the slower temperature transmission speed can hinder the furtherspreading of fire, and the flame retardancy of the TPU film and the composite fabric is enhanced.

Description

technical field [0001] The invention relates to the field of TPU composite fabrics, in particular to a flame-retardant TPU composite fabric. Background technique [0002] Thermoplastic polyurethane (TPU) is a new type of organic polymer synthetic material that has emerged in recent years. Its outstanding features are good processing performance, excellent wear resistance, excellent ozone resistance, high strength, good elasticity, and good low temperature resistance. It is a new type of polymer material with oil resistance, chemical resistance and environmental resistance. However, thermoplastic polyurethane (TPU) also has disadvantages. Due to its poor flame retardancy, the application of TPU materials in the field of composite fabrics is limited. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the present invention provides a flame-retardant TPU composite fabric, which improves the temperature resistance level of the TPU film, d...
