Abstract

The invention discloses a preparation method of carbon nanotubes / nano ATO (antimony tin oxide) / polypropylene electroconductive fibers. The preparation method comprises the following steps of: (1) mixing nano ATO and carbon nanotubes, placing in an organic solvent together with a dispersant, and carrying out surface treatment to obtain a double-component nano electroconductive agent; (2) mixing the double-component nano electroconductive agent with polypropylene slices, and carrying out melt blending and strip preparation and granulation with a screw extruder to obtain double-component nano electroconductive agent / polypropylene composite electroconductive slices; (3) carrying out melt spinning on the composite electroconductive slices to obtain carbon nanotubes / nano ATO / polypropylene nascent electroconductive fibers; and (4) stretching and shaping the carbon nanotubes / nano ATO / polypropylene nascent electroconductive fibers to obtain the carbon nanotubes / nano ATO / polypropylene electroconductive fibers. By using the preparation method, the filling factor of a filler is increased, the content of an electroconductive filler in the material is reduced, the electric conductivity of the material is improved, and the electric performance stability of the material is simultaneously improved; and the preparation method has low price and no special requirement on equipment, has a economicand simple process route, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of composite fiber and its preparation, in particular to a carbon nanotube / nano-ATO / polypropylene composite fiber and a preparation method thereof. Background technique [0002] Compared with natural fibers, synthetic fibers have the advantages of high strength and wear resistance, and have been widely used in various fields. Static electricity is easily generated due to friction during processing or use. When the accumulated static electricity is higher than 500V, sparks will be generated due to discharge and cause a fire. When the static electricity is higher than 8000V, electric shock will occur. Therefore, since the advent of synthetic fibers, people have been devoting themselves to various researches on antistatic aspects. Especially in the past ten years, the development and research progress in the application field of polymer chemistry has made some progress in improving the antistatic property and durability...
