Problems solved by technology

Due to the existence of micro-cracks, the glass is subjected to uneven force under the action of external force, and stress concentration occurs at the most harmful micro-cracks, thereby reducing the strength, which seriously limits the practical application of glass fibers in many high-temperature environments.

Abstract

The invention relates to a glass fiber chemical polishing agent and a preparation method and application thereof, in particular to a chemical polishing agent capable of effectively reducing the surface roughness of glass fibers and a preparation method thereof, and belongs to the technical field of glass fiber manufacturing, the technical field of organic / inorganic chemical engineering and the field of thermal protection base materials. The roughness of the glass fiber is reduced to 53-92 nm from 210 nm or above, and the tensile strength of the monofilament is remarkably improved to 1205-1654MPa from 917 MPa; the surface roughness of the glass fiber treated by the polishing agent is obviously reduced, and then the micro-defect size and quantity are obviously reduced and the strength of the glass fibers is obviously improved; in addition, the glass fiber polishing agent has the greatest characteristics of simple preparation process, wide raw material source, low price, simple and feasible treatment process, large mechanical property improvement amplitude and the like.

Description

technical field [0001] The invention relates to a chemical polishing agent for glass fiber and its preparation method and application, in particular to a chemical polishing agent for effectively reducing the surface roughness of glass fiber and its preparation method, which belongs to the technical field of glass fiber manufacturing and also belongs to organic / inorganic chemical industry The technical field also belongs to the field of thermal protection basic materials.
