The invention belongs to the field of sleepers, and relates to polyethylene foamed plastic products, in particular to a PE foamed sleeper and a preparation method thereof. The PE foamed sleeper comprises polyethylene foamed plastic, graphene fibers, glass fibers, desiccant and coupling agent , flame retardant; its preparation method comprises the following steps: 1) mixing the components to obtain polyethylene foam; 2) mixing polyethylene foam, graphene fiber, glass fiber, desiccant, coupling agent and flame retardant 3) Melt the diced mixture, add miniature spring nails into the molten material, and transport it to the molding die for shaping, that is, to obtain PE foaming sleeper. The invention has the characteristics of light weight, good corrosion resistance, high flame retardancy, excellent mechanical properties, etc. The addition of graphene fibers, glass fibers and miniature spring nails greatly improves the toughness, tensile strength and integrity of the sleeper. |
