A kind of method for preparing glass conductive fiber by chemical reaction method

Abstract

The invention provides a method for preparing conductive glass fibers through a chemical reaction method. Glass fibers are subjected to surface treatment by adopting vacuum plasmas, glass fibers treated through the plasmas are soaked into a carboxylation chitosan aqueous solution, taken out to be soaked into a glutaraldehyde solution, taken out to be fully rinsed with water and dried, and then glass fibers subjected to surface modification through carboxylation chitosan are obtained; the glass fibers subjected to surface modification through carboxylation chitosan are placed into a copper sulfate pentahydrate aqueous solution to be soaked, a sodium thiosulfate aqueous solution is added, the glass fibers are taken out after reacting to be rinsed with water and dried, and then the cuprous sulfide-glass fiber composite conductive fibers are obtained. The conductive glass fibers are prepared by adopting the method, the adopted equipment investment cost is low, operation is easy, the reaction conditions are mild, the applicability is high, the treatment effect is good, little fiber performance loss is generated, the quality is reliable, environmental pollution can be reduced, and the method is suitable for industrialized production.

Description

technical field

[0001] The invention relates to the post-treatment field of glass fibers, in particular to a method for preparing conductive glass fibers by a chemical reaction method. Background technique

[0002] In recent years, with the rapid development and popularization of computers, telecommunications, microwave ovens, etc., the electromagnetic radiation in the living and working environment of human beings has become increasingly serious. The resulting electromagnetic wave interference has brought many negative effects to the normal operation of electronic equipment and human physical health. influences. In order to prevent electrostatic interference and electromagnetic wave interference, various antistatic and electromagnetic shielding materials have been developed since the middle of the 20th century. 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 i...
