Abstract

The invention discloses a manufacture method of a high-strength TPU (thermoplastic polyurethane) compound fabric, which solves the problems of uneven film, low yield and high cost of the TPU compound fabric produced by adopting the traditional production method of the TPU compound fabric. A TPU film is produced with high production efficiency and low cost by adopting a process of calendering with a four-roller calendar. Because the produced TPU film has uniform thickness, the produced high-strength fabric has the advantages of uniform cloth, good compound fabric, high coating strength, high airtightness and high abrasive resistance, and can be widely applied to the fields of airships, surface-effect ships, oil containment booms, lifesaving devices, supplementary restraint systems and the like.

Description

technical field [0001] The invention relates to a method for manufacturing a high-strength TPU (thermoplastic polyurethane) composite fabric. Background technique [0002] The traditional production methods of TPU composite fabrics include impregnation, coating and scraping, film lamination and online extrusion casting. The film is made by blown film method and casting method. The disadvantages are uneven film, low output and high cost. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing method of high-strength TPU composite fabric to solve the problems of uneven film, low output and high cost of the TPU composite fabric produced by the existing TPU composite fabric production method. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A manufacturing method of high-strength TPU composite fabric, comprising the following steps: [0006] (1) The manufacture of TPU f...
