[0003] The general water-resistant PVC cable sheath material is usually a single-layer structure, in which nitrile rubber, modified potassium feldspar powder, nano-silicon dioxide, XT-3 rare earth stabilizer and other materials are added to the raw material of PVC polyvinyl chloride to improve the waterproof ability and strength of the sheath. However, this single-layer structure has a relatively simple effect, a complex process, uneven quality and is relatively inconvenient to produce. A Chinese patent discloses a wire and cable sheath material with application number "CN202123079827.0", including a weather-resistant protective sleeve, a flexible reinforcing cloth layer, a fireproof cloth layer, a flexible fireproof filler, an inner insulating protective sleeve, a polyvinyl chloride protective tube and an alarm device, wherein the alarm device includes a temperature-sensitive optical fiber, a processing module, a power supply module and an alarm, wherein the weather-resistant protective sleeve is coated on the outside of the flexible reinforcing cloth layer, and a fireproof cloth layer is provided inside the flexible reinforcing cloth layer, and a flexible fireproof filler is provided inside the fireproof cloth layer, and several inner insulating protective sleeves and polyvinyl chloride protective tubes are provided inside the flexible fireproof filler, and the inner insulating protective sleeve is coated on the outside of the polyvinyl chloride protective tube, and the core of the cable is provided inside the polyvinyl chloride protective tube, and a temperature-sensitive optical fiber is buried inside the flexible fireproof filler. The wire and cable sheath material has good protective effect, which greatly increases the service life and safety performance of the cable. However, this structure does not solve the problem that the sheath material structure is not water-resistant. Utility Model Content
