[0005] CN104015444A discloses a thermoplastic polyurethane / fiber composite soft cloth and its preparation method. The disclosed composite soft cloth uses TPU and fiber fabrics of different colors as raw materials, and the TPU and fabric are bonded together in the form of heat lamination. It achieves the effects of zero pollution, simple process, and low cost. However, the composite cloth made by thermal lamination still has defects such as poor air permeability and insufficient mechanical strength.
[0006] CN103483801A discloses a thermoplastic polyurethane composite material and its preparation method, which adopts the thermoplastic polyurethane composite material, adding basalt fiber as a reinforcing material, and adopts a melt extrusion process to prepare the thermoplastic polyurethane composite material, so that the thermoplastic polyurethane composite material and Compared with polyurethane composite materials using ordinary glass fibers, mechanical properties and heat resistance have been significantly improved. However, composite materials made by co-melting and extruding fiber materials with thermoplastic polyurethane will have poor air permeability , therefore, methods such as shoe materials and clothing accessories cannot be widely used in fields that require high air permeability

Abstract

The invention relates to a novel high-performance TPU composite material and a preparation method thereof. The core part of the TPU composite material is a silk yarn or a cotton thread, and a layer of TPU material is wrapped on the outer surface of the core part. The preparation method comprises the following steps: firstly, extruding the TPU material by using an extruder; and then, wrapping the TPU on the silk yarn or the cotton thread by virtue of a wrapping technology to form another kind of yarn so as to obtain the TPU composite material provided by the invention. The material can be wound to form a coil or can be directly prepared into a textile. By jointly weaving the silk yarn or the cotton thread and the TPU material, the TPU composite material which is good in air permeability and high in mechanical strength is manufactured. The composite material further has the advantages of wear resistance, flame resistance, yellowing resistance, mould proof, bacteria prevention and the like.

Description

technical field [0001] The invention belongs to the field of composite material preparation, and in particular relates to a TPU composite material and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer rubber (TPU) is a kind of linear multi-block polymer formed by alternating thermodynamically incompatible hard segments and soft segments, which has a unique microphase separation structure, so its physical and mechanical properties are quite excellent. The outstanding features of TPU are high hardness, high strength, good elasticity, low temperature resistance, excellent wear resistance, excellent ozone resistance, good oil resistance, chemical resistance and environmental resistance. Therefore, it is widely used in injection molding. , Extrusion, calendering and dissolving into solution resin and other processing methods, its products cover the range of industrial applications and civil necessities. [0003] Thermoplastic polyu...
