Oil-resistant and high-temperature-resistant ship cable

Abstract

The invention relates to an oil-resistant and high-temperature-resistant ship cable, which sequentially comprises a conductor, a belting layer, an insulating layer, a fiber braided reinforcing layer,a sheath, a glass fiber braided layer and a coating layer from inside to outside, wherein the insulating layer and the sheath are respectively made of a silicon rubber, the insulating layer comprisesa fluorosilicon rubber, No.2 fumed silica, nano tin oxide, praseodymium oxide, methylphenyldiethoxysilane, hydroxyl fluorosilicone oil, mica powder, talcum powder, benzoyl peroxide, nano magnesium hydroxide, stearic acid and carbon black, and the sheath comprises a fluorosilicon rubber, a chlorosulfonated polyethylene rubber, a natural rubber, an epoxidized natural rubber, a filling reinforcing agent, dioctyl phthalate, triallyl trimellitate, hydroxyl silicone oil, hydrogen-containing silicone oil, a silane coupling agent, magnesium oxide and calcium hydroxide. The oil-resistant and high-temperature-resistant ship cable has advantages of excellent physical and mechanical properties, good oil resistance, good high-temperature resistance, good wear resistance, good insulation property and good flame retardance, can obviously reduce the aging speed, and can be applied to cables for ships.

Description

technical field [0001] The invention belongs to the technical field of ship cables, and in particular relates to an oil-resistant and high-temperature-resistant ship cable. Background technique [0002] With the increase of trade volume between countries, the volume of goods transported by sea is also increasing, and ocean-going freighters are an important tool for maritime transport, and the control cables are responsible for transmitting the electrical signals of the controller to the machine. Safe navigation at sea is of great significance. At present, the existing marine cables are required to have high temperature resistance, oil resistance, and acid and alkali resistance due to their application in special environments. Therefore, ship cables made of ordinary cross-linked polyolefin materials cannot meet the operating requirements, and silicone rubber materials are required. [0003] Silicone rubber is an excellent material for making control cable insulation due to ...

Problems solved by technology

However, the engine room of a ship is often filled with various oils and high temperatures. The insulating layer made of ordinary silicone rubber is easily damaged by corrosion. Silicone rubber will swell after contact with oil stains and corrode, resulting in a significant increase in the tensile strength, insulation performance and wear resistance of silicone rubber. Decline, resulting in unstable operation of the ship, and even lead to safety accidents

[0004] Chinese patent CN 107705888A discloses a high-strength and pressure-resistant fire-resistant cable for ships, including a cable core, a filling unit, a tape layer, a braid layer, and a sheath layer. Ceramic silicon rubber materials are used as the insulation layer and sheath layer of the cable. The sheath layer takes advantage of its fire-resistant characteristics. In the event of a fire or a high temperature of 800-900°C, the cable will be in a ceramic state to prevent a short circuit from affecting the power supply of the cable; however, the cable in this patent has poor oil resistance and may corrode after contact with oil. , which affects its use and is limited in ship applications
