Abstract

The invention discloses a preparation method of organic matter-modified glass fiber. The method comprises the steps of (1) putting glass fiber into hydrogen peroxide, and heating for carrying out oxidation treatment; (2) soaking the glass fiber, subjected to the oxidation treatment, into a titanate coupling agent to obtain pretreated glass fiber; (3) mixing the pretreated glass fiber with epoxy resin, and heating to obtain the organic matter-modified glass fiber, wherein the length of the glass fiber is 85-100mu m, and the volume concentration of the titanate coupling agent is 5-15%. The organic matter-modified glass fiber prepared by the method is high in toughness and great in elongation, and can reach the effect of resisting wear.

Description

technical field [0001] The invention relates to glass fibers, in particular to organic matter modified glass fibers and a preparation method thereof. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds of it. It has good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Glass fiber is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns. All are composed of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. However, the poor wear resistance of currently commercially available glass fibers limits its popularization. Contents of the invention ...
