Abstract

The invention discloses a high-strength and pressure-resistant fire-resistant cable for ships, which includes a cable core, a filling unit, a wrapping layer, a braiding layer and a sheath layer. The invention also discloses a preparation method of a high-strength and pressure-resistant fire-resistant cable for ships; including (1) preparation of a single cable core; (2) preparation of a cable core unit; (3) preparation of a tape layer ;(4) Preparation of the braiding layer; (5) Preparation of the sheath layer; Ceramic silicone rubber material is used as the insulation layer and sheath layer of the cable to play its fire-resistant characteristics. In case of fire or high temperature 800‑900 At ℃, the cable will be in ceramic state to prevent short circuit from affecting the power supply of the cable; the ceramicized silicon rubber belt is used as filling, and it will form a hard ceramic structure at high temperature or fire, which will not be carbonized and affect the structure. Polyolefin materials give full play to their respective advantages. Aramid fiber has high tensile strength, and ceramic polyolefin materials have good fire resistance. The braided layer is mesh-shaped, which can effectively protect the strength of the cable.

Description

technical field [0001] The invention relates to a fire-resistant cable for ships, in particular to a high-strength and pressure-resistant fire-resistant cable for ships and a preparation method thereof. Background technique [0002] At present, the basic structure of fire-resistant cables for ships in my country is insulated core, glass fiber filled rope, mica wrapping tape, steel tape armor and PVC sheath. With the development of modernization and national defense construction, higher requirements are put forward for fire-resistant cables for ships. Conventional cables have defects in tensile performance on ships, poor lateral pressure resistance, not easy to step on, and insufficient fire resistance, etc. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a high-strength and pressure-resistant fire-resistant cable for ships, wh...
