The invention relates to the technical field of rubber and plastic pipes, in particular to a novel double-aperture rubber and plastic heat-insulation pipe which comprises two first pipe holes, wherein an inner protection layer is arranged on the inner wall of each first pipe hole; the structure, the formula and the process of the novel double-aperture rubber-plastic heat-insulation pipe are improved, and the inner protective layer can be recycled through the design of the inner protective layer, the first pipe hole, the heat-insulation rubber-plastic, the outer sheath and the second pipe hole, so that the heat-insulation rubber-plastic heat-insulation pipe is quickly degraded, can be recycled, is green and environment-friendly, and is beneficial to virtuous cycle of an ecological chain; the novel rubber-plastic heat-insulating pipe obtained by the manufacturing process has excellent performance and can be widely applied to the fields of buildings and the like. |
