Problems solved by technology

These two kinds of metal sheath tubes provide a certain protection for cables, but these two alloy materials will produce electrochemical reactions with steel in seawater or high salinity environments, which greatly accelerates the corrosion rate of steel, which is harmful to ship steel. The surface of the structure causes great damage, which increases the maintenance cost of the ship system; because the metal cable sheath tube is made of hard material, it cannot fit well with the soft cable, and the sealing effect is poor, and the protection function of the cable is poor. Reduced, and it is difficult to change the route during installation; at the same time, the weight of the metal sheath pipe is relatively large, which increases the weight of the hull and increases the difficulty of its installation and fixing

Abstract

The invention discloses a cable sheath tube for ships, which is prepared by the following steps of: pre-processing, mixing, granulating and drying a mixture of a basic resin, an elastomer, an antioxidant, a light stabilizer, a flame-retardant system, a softening agent, a mildew inhibitor, a radiosensitizer and a color master batch; forming the tube with the materials; and finally irradiating the formed tube by an electron beam. The cable sheath tube prepared by the invention has high elasticity and flexibility, low-smoke, zero-halogen, excellent flame retarding effect, high corrosion resistance, high aging resistance, high mechanical strength, high sealing performance, simple and convenient installation and easy change and installation of a route and effectively solves the problems of protection of various power cables and signal cables inside and outside the ships.

Description

Technical field [0001] The invention relates to the technical field of processing cable sheath tubes prepared by polymer materials, in particular to a cable sheath tube for ships and a preparation method thereof. technical background [0002] With the continuous improvement of the electrification and automation of ships, the planning and safe operation of power systems have become an important part of modern shipping equipment. All kinds of power cables and signal cables distributed inside and outside the ship are responsible for providing power supply and signal transmission for various electrical equipment on the ship. Ships operate in a harsh environment of high humidity, high heat, and high salinity corrosion all year round. Marine cables directly exposed to this harsh environment will gradually age or even be damaged. The aging of cables is a major hidden danger that threatens the navigation safety of ships. Insulation failures caused by aging problems account for a la...
