The invention discloses a core layer microcellular foaming PVC/CPVC cable protection tube and a preparation method thereof, wherein the core layer adopts a halloysite nanotube structure filled with foaming agent for foaming, the weight of the tube is reduced, the anisotropy of the material structure is ensured, the mechanical property reduction caused by the foaming of the tube is overcome, and TiO is loaded on the surface of the halloysite nanotube 2 Anti-ultraviolet aging and avoids TiO 2 Agglomeration; the inner layer adopts a reinforced and modified solid-wall pipe structure, so that the pipe is reinforced, and the smoothness of the inner wall and the overall compressive strength of the pipe are ensured during cable penetration; the outer layer adopts a toughened and modified solid-wall pipe structure, so that the impact resistance of the pipe in the transportation process and the bending and pulling strength of the pipe in the construction process are ensured. |
