Preparation method of conductive composite glass fiber yarn

Abstract

The invention discloses a preparation method of a conductive composite glass fiber yarn. The conductive composite glass fiber yarn is prepared by pyrophyllite, kaolin, quartz sand, mirabilite, borax,dolomite, graphite oxide, N,N-dimethylformamide, hydriodic acid, acetic acid, calcium hydroxide, ferrous sulfate, hydroxypropyl methyl celluloses and other raw materials. The preparation method disclosed by the invention has the benefits that the glass fiber yarn is prepared by melting and wire-drawing the pyrophyllite, the kaolin, the quartz sand and the other raw materials; the negatively-charged graphite oxide coats the glass fiber surface under the action of electrostatic adsorption; subsequently, the graphite oxide coating the glass fiber surface is reduced by adopting the hydroiodic acidto obtain a graphite-coated glass fiber composite conductive material; finally, the obtained glass fiber yarn has excellent compressive strength, flexural strength and ideal electrical conductivity and has a wide application prospect as a conductive fabric resistant to electromagnetic radiation; meanwhile, the preparation process is simple and easy to implement, the raw materials are cheap and easy to obtain, and the demands of people on the functionality of the glass fiber yarn are met.

Description

technical field [0001] The invention relates to the technical field of glass fiber materials, in particular to a preparation method of conductive composite glass fiber yarn. Background technique [0002] With the advancement of technology, the use of electronic products is expanding by leaps and bounds, and the resulting electromagnetic wave interference has brought many negative effects on the normal operation of electronic equipment and human physiological health. Therefore, electromagnetic shielding materials are becoming more and more popular among people. s concern. In recent decades, the focus of research has shifted more to conductive fibers. The antistatic effect of conductive fibers is more significant and durable, and it is not affected by environmental humidity. When the conductive layer reaches a certain thickness or the conductive component reaches a certain proportion, it has excellent performance. Electromagnetic shielding function, so the development and app...
