The present application relates to the technical field of layered products, specifically to a flame-retardant, antibacterial, and sound-insulating composite fiberboard and a preparation method thereof, wherein the flame-retardant, antibacterial, and sound-insulating composite fiberboard is composed of a sound-insulating, flame-retardant layer, a reinforcing layer, an antibacterial, and flame-retardant layer, and a finishing layer in sequence; the sound-insulating, flame-retardant layer is made by hot-melt bonding of sisal fiber, polyester fiber, and collagen fiber, and then adding a first flame retardant to mix; the reinforcing layer is a mesh-like structure made by hot-melt bonding of aramid fiber and bamboo fiber; the antibacterial, flame-retardant layer is made by hot-pressing a mixture of raw materials including bamboo charcoal activated carbon, a second flame retardant, and volcanic rock particles; the finishing layer is a non-woven fabric surface layer; the sound-insulating, flame-retardant layer, the reinforcing layer, the antibacterial, and flame-retardant layer, and the finishing layer are bonded by adding PMMA powder and hot-baking and pressing. The present application realizes the autonomous bonding of the composite fiberboard by cross-linking different functional layers, thereby improving the flame-retardant, antibacterial, and sound-insulating properties of the composite fiberboard, while reducing the formaldehyde content of the composite fiberboard and improving the quality of the living environment.

The application provides a high-strength steel wire rope core, which comprises a center wire, a secondary outer layer wire and an outer layer wire. The center wire is a steel wire bundle, the steel wire bundle is composed of 6-18 thin steel wire bundles; the secondary outer layer wire spirally wraps the center wire, the secondary outer layer wire comprises 4-12 first modified sisal wires; the outer layer wire spirally wraps the secondary outer layer wire, the outer layer wire comprises a first combined wire and a second modified sisal wire, the second modified sisal wire is arranged in the gap between adjacent first combined wires; the first combined wire comprises a second steel wire and a plurality of ultra-high molecular weight polyethylene wires, and the ultra-high molecular weight polyethylene wire spirally wraps the second steel wire. Wherein, the first modified sisal wire and the second modified sisal wire are both graphene oxide-polyethyleneimine modified sisal wires. The multi-layer composite structure is adopted, so that the strength of the steel wire rope core is improved as a whole, and the steel wire rope core has high tensile resistance and supporting property.
