Abstract

The invention discloses a high-temperature resistant conducting fiber and a preparation method thereof. The high-temperature resistant fiber takes silicon oxide fiber as a carrier, and is prepared by employing a liquid phase coating method to coat a layer of ATO (antimony doped tin oxide) on a fiber surface. The conducting fiber has good conductivity and antioxidation, and resists high temperature; the product has wide application, can be applied to the modification of materials such as paint, rubber and the like, and also can be applied to the manufacture of antistatic ceramics and electric heating ceramics.

Description

technical field [0001] The invention relates to a fibrous conductive powder and a preparation method thereof, in particular to a high temperature resistant conductive fiber and a preparation method thereof. Background technique [0002] With the rapid development of the electronics industry and the improvement of people's living standards, conductive powder, as a functional filler in the preparation process of plastics, coatings, chemical fibers, rubber and ceramics, can endow it with antistatic, electromagnetic shielding and other properties, which has aroused people's interest. extensive attention. Commonly used conductive powders mainly include metal-based powders, carbon-based powders, and doped metal oxide powders (ATO, ITO, conductive zinc oxide), etc. [0003] As a conductive filler, a certain amount of conductive powder is added to the matrix (paint, ceramics, rubber, etc.), and a perfect conductive network is formed in it to make it have a certain conductivity. ...
