Abstract

The invention provides a salt-spray-resistant coating used for a cable and a preparation method thereof. Directed at the phenomenon of corrosion of a submarine cable due to easy generation of crystalline salt on the surface of the sumarine cable after long-term use, the salt-spray-resistant coating provided by the invention is researched and developed. The coating provided by the invention comprises the following components: EPDM rubber, petroleum ether, disodium methylene dinaphthalene phosphate, cyclopentanol, idesia oil, zinc borate, an auxiliary agent, trioctyl trimetabenzoate, an anti-drip agent , nanometer bauxite and celestine powder. The salt-spray-resistant coating provided by the invention is prepared from the above-mentioned raw materials through a scientific and reasonable proportion. Through coating of the salt-spray-resistant coating provided by the invention onto the surface of the cable, the surface of the cable can be prevented from generating the crystalline salt; theservice life of the cable is prolonged; practice proves that the service life of the cable can be prolonged by 2 to 4 years; and the salt-spray-resistant coating is worth popularization and application.

Description

technical field [0001] The invention belongs to the technical field of cable coatings, and in particular relates to an anti-salt spray coating for cables and a preparation method thereof. Background technique [0002] With the development of the industry, the production and manufacture of wire and cable has also developed by leaps and bounds. The development process of wire and cable products is essentially a process of upgrading materials. Wires and cables have a wide range of uses, and their performance requirements vary greatly in different applications. The insulation of most cables must have good physical and mechanical properties in addition to high insulation resistance, withstand voltage strength or low dielectric loss. , such as tensile resistance, bending resistance, vibration resistance, torsion resistance, etc.; and sheath materials, due to different use environments and occasions, have tear resistance, high and low temperature resistance, weather resistance, oi...
