Embodiment 1

[0035] The surface of glass fiber is dense and smooth and contains less active groups, which is not conducive to the absorption and diffusion of dye molecules, which seriously affects the coloring performance of the fiber. In order to produce colored glass fibers, the present invention does not dye the glass fibers after the glass fibers are formed, but adds non-ferrous alloys to the raw materials of the glass fibers to produce the required colored glass fibers. In order to ensure the coloring of non-ferrous alloys, a color-fixing agent is added to fix the color, so that the solution has color, and then drawn to form colored glass fibers.

[0036] High-strength colored glass fibers refer to glass fibers whose tensile strength is at least higher than 2500MPa.

[0037] The inert gas system in the present invention refers to a closed environment filled with inert gas.

[0038] The specific process of the present invention is as follows.

Abstract

The invention discloses a preparation method of high-strength colored glass fiber, and discloses a preparation method of producing high-strength colored glass fiber by coloring with a non-ferrous alloy and then heat-treating. The colored alloy of the invention is evenly mixed with the color fixing agent to make the coloring uniform, and then the high-strength colored glass fiber is obtained through dry spinning, laminar flow plasma spraying and heat treatment. Heat treatment does not change the shape and overall chemical composition of the workpiece, but by changing the microstructure inside the workpiece, or changing the chemical composition of the surface of the workpiece, endows or improves the performance of the workpiece, and improves the toughness and strength of the colored glass fiber. The color of the high-strength colored glass fiber produced by the invention is stable and uniform, and is not easy to spread.

Description

technical field [0001] The invention belongs to the field of preparation of glass fiber surface treatment and dyeing coating, in particular to a preparation method of high-strength colored glass fiber. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance and a wide range of uses. It is an important part of the new technological revolution marked by materials, energy and information.
