Abstract

The invention discloses a preparation method of polymer-modified glass fibre. The method comprises the following steps: (1) glass fibre is placed in a solution of hypochlorous acid with heating for carrying out oxidation treatment; (2) after the oxidation treatment, the glass fibre is immersed in a titanate coupling agent in order to obtain pretreated glass fibre; (3) pretreated glass fibre and epoxy resin are mixed and heated, in order to obtain the polymer modified glass fibre; wherein, the length of the glass fibre is 110-140 [mu]m; the volume concentration of the titanate coupling agent is 25-45%. The polymer modified glass fibre has the characteristics of high toughness and wear resistance.

Description

technical field [0001] The invention relates to glass fibers, in particular to polymer 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, due to the poor toughness and wear resistance of glass fiber, its popularization is limited. Contents of the invention [0003] One of t...
