Abstract

The present invention discloses a fire-resisting cable with high strength and pressure resisting for a ship. The cable comprises a cable core, a filling unit, a taping layer, a braided layer and a sheath layer. The present invention further discloses a preparation method of a fire-resisting cable with high strength and pressure resisting for a ship. The method comprises the following steps of: (1)preparation of a single cable core; (2) preparation of a cable core unit; (3) preparation of the taping layer; (4) preparation of the braided layer; and (5) preparation of the sheath layer. Ceramic silicone rubber materials are employed as an insulation layer and the sheath layer of the cable, a fire-resisting feature of the ceramic silicone rubber materials is developed, and when fires occur orat a high temperature of 800-900 DEG C, the cable is in a ceramic state, so that short circuit is avoided to influence power supply of the cable; and moreover, a ceramic silicone rubber tape is takenas a filler and is a ceramic hard titanium structure at a high temperature or when fires occur, the structure cannot be influenced by being carbonized, ceramic polyolefin materials are extruded on aramid fibers, each advantage is developed, the strength of extension of the aramid fibers is large, the ceramic polyolefin materials are good in fire-resisting capability, and the braided layer is a netto effectively provide 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...
