Abstract

The present application relates to the technical field of a macromolecular material, and particularly to a creep-resistant fiber and a preparation method thereof. The creep-resistant fiber includes the following components: ultra-high molecular weight polyethylene, epoxy resin, graphene, nano-silicon carbide and mica. The preparation method thereof is that: S1. preparing an ultra-high molecular weight polyethylene fiber spinning solution; S2. swelling and performing extrusion spinning to obtain a filament; S3. after spinning, passing the filament through a spinneret plate, and shock cooling in a cold water bath; S4. preparing a crosslinking modification solution; S5. conducting ultrasonic extraction; S6. drying and hot stretching to obtain a creep-resistant ultra-high molecular weight polyethylene fiber.
