Problems solved by technology

[0002] Due to the comprehensive properties of thermoplastic elastomers such as outstanding mechanical strength, excellent resilience and wide service temperature, they have been widely used in the fields of automobile parts, hydraulic hoses, cables and wires, electronic appliances, industrial products, stationery, and biological materials. Wide range of applications, but the application is limited due to the difficulty in meeting the requirements of heat resistance, strength and its modulus in some application fields
[0003] In recent years, there have been a lot of studies on the modification of thermoplastic elastomers, most of which are filled with some micron-sized fillers or nano-fillers for filling modification, but fillers are difficult to disperse evenly in elastomers, and there is agglomeration phenomenon, which will affect thermoplastic elastomers.

Abstract

The invention discloses an in-situ-formed-fiber-reinforced thermoplastic elastomer film material and a preparation method thereof. By selecting the proper thermoplastic elastomer and fiber forming phase, the thermoplastic elastomer, the fiber forming phase, a compatilizer and other aids are directly added into twin screws of a micro / nano lamination extrusion device to perform extrusion, and the mixture is further stretched under the intense shearing action of the stream middle layer multiplier of the polymer micro / nano lamination coextrusion device and further stretching after extrusion so as to improve the compatibility between the fiber forming phase and the thermoplastic elastomer, so that the microfibers formed by the fiber forming phase are dispersed uniformly in the thermoplastic elastomer. The diameter of the microfibers can reach nano scale, the fiber dimension is controllable, and the fibers can well improve the properties of the thermoplastic elastomer film material and effectively enhance the tensile properties and mechanical properties of the thermoplastic elastomer. The thermoplastic elastomer film material has the advantages of simple processing method and controllable and stable product properties, and can easily implement industrial production.
