Abstract

The invention relates to a production process of a novel high-performance TPU composite material. The production process comprises the following steps: firstly, extruding a TPU material by using an extruder; and then, wrapping the TPU on a silk yarn or a cotton thread by virtue of a wrapping technology 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 a fiber layer 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, bacterial prevention and the like.

Description

technical field

[0001] The invention belongs to the field of composite material preparation, in particular to a production process of TPU composite material. Background technique

[0002] Thermoplastic polyurethane elastomer (TPU) is a kind of linear multi-block polymer formed by alternating thermodynamically incompatible hard segments and soft segments. It has a unique microphase separation structure, so its physical and mechanical properties are quite excellent. . The outstanding features of TPU are large hardness range, high strength, good elasticity, low temperature resistance, excellent wear resistance, excellent ozone resistance, and good oil resistance, chemical resistance and environmental resistance. Therefore, it is widely used in Processing methods such as injection molding, extrusion, calendering and dissolving into solution resins, its products cover the scope of industrial applications and civilian necessities.

[0003] Thermoplastic polyurethane (TPU) has ou...
