Abstract

The invention relates to a graphene-based reinforced fiber for plastic bellows and a preparation method thereof. By preparing the graphene to a slurry, the slurry is sprayed onto the spun ultra-high molecular weight polyethylene fiber to obtain the reinforced fiber, the continuous scale production can be realized, the operation is simple, cost is low, and the efficiency is high. The obtained graphene-based reinforced fiber has rich surface roughness structure and strong binding ability to a pipe matrix, promotes the dispersion of graphene in the plastic bellows, can significantly improve the strength and ring stiffness of the bellows, and enhance the resistance of the bellows to deformation; a sizing agent, a dispersing agent and an emulsifier are added to a graphene film to make the filmforming property and the dispersing property better, and the material is more uniform.

Description

technical field [0001] The invention relates to the technical field of super-strength fibers and their preparation, in particular to a graphene-based reinforcing fiber for plastic corrugated pipes and a preparation method. Background technique [0002] Today, when protecting the environment and saving energy, the use of plastic double-wall corrugated pipes is in line with the country's development direction of replacing cement pipes, steel pipes, and cast iron pipes with plastic pipes. Polyvinyl chloride (PVC) plastic pipe has excellent physical and chemical properties such as good flame retardant effect, strong acid and alkali resistance, high structural strength, and good electrical insulation. It is currently one of the most widely used plastic pipes on the market. Among them, PVC bellows are widely used in engineering fields. However, the tensile level and toughness of PVC corrugated pipes are poor, and local brittle fractures are prone to occur when subjected to large ...
