Abstract

The invention discloses a preparation method of composite glass fibers. The method comprises the following steps: (1) putting glass fibers in hypochlorous acid solution to be heated and then carrying out oxidation treatment; (2) soaking the glass fibers subjected to the oxidation treatment in a silane coupling agent to obtain pretreated glass fibers; (3) mixing the pretreated glass fibers with polylactic acid and heating to obtain the composite glass fibers, wherein the lengths of the glass fibers are 65-80 mum; the volume concentration of the silane coupling agent is 25 to 45%. The composite glass fibers prepared through the method are high in toughness and large in elongation, and capable of reaching a wear resistant effect.

Description

technical field [0001] The invention relates to glass fibers, in particular to composite 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 [0003] One of ...
