Abstract

The invention provides a laminating orientation extrusion method of rubber short fiber and an extrusion device. A number of laminating, torsion and merging stages are employed to suit extrusion molding control accuracy of a short fiber-rubber composite material, and the laminating orientation of short fiber is controlled in an extrusion process, so as to realize uniform distribution of short fibers in each film layer along horizontal and vertical direction, and improve wear resistance of the composite film. The extrusion method is as below: compounding the short fibers to the film; in the extrusion process, subjecting a monolayer film to at least 2 stages of stratification, torsion and combination, and stretching the film at least once between adjacent stages, so as to eventually form a composite layer film structure; and multiplying the number of layer at each stage to obtain the number of layer of a final film composite layer, wherein in each layer of film, short fibers are distributed along horizontal and vertical direction of the film.

Description

Technical field [0001] The invention relates to a method and a device for controlling the orientation, composite lamination and extrusion of short fibers in a rubber composite material to implement uniform distribution of the short fibers in the horizontal and longitudinal directions of the film, and belongs to the field of rubber machinery and automatic control. Background technique [0002] With the rapid development of domestic and foreign air transportation and automobile industries, comprehensive high-performance requirements have been put forward for rubber tires. In addition to the improvement of tire structure design, the improvement of tire raw material properties has always been a research focus. [0003] The development and application of polymer materials at the current stage has shifted from large-scale synthesis of new polymer compounds to the use of various methods to modify existing polymers. Using short fibers to enhance the performance of tire tread rubber is an ...
