Problems solved by technology

[0003] Control cables have the characteristics of moisture-proof, anti-corrosion and anti-damage, and can be laid in tunnels or cable trenches. They are easily attacked by rats and ants and cause potential safety hazards. Therefore, it is necessary to increase their anti-rodent and ant-proof performance.
[0004] Polyvinyl chloride is commonly used as insulating material and sheath material for control cables, but polyvinyl chloride contains chlorine, which will increase the amount of smoke released when burned, release corrosive gases, and pollute the environment, so halogen-free plastic or rubber materials must be used as insulation and sheath material, but its flame retardancy is low, and its flame retardancy needs to be increased

Abstract

The invention discloses a rat-proof and ant-proof low-smoke halogen-free flame-retardant control cable for warships, which comprises insulating wire cores, a halogen-free flame-retardant belt and a sheath layer. Each insulating wire core comprises a conductor and an insulating layer arranged outside the conductor by extrusion. The cable core is wrapped with the halogen-free flame-retardant belt. The sheath layer is arranged by extrusion outside the halogen-free flame-retardant belt. The sheath layer comprises the following raw materials by weight: 80-100 parts of ethylene propylene diene monomer, 30-40 parts of filler, 2-6 parts of plasticizer, 1-2 parts of cross-linker, 0.5-0.6 parts of cross-linking auxiliary, 25-35 parts of flame retardant, 2-4 parts of flame retarding auxiliary, 1-3 parts of antioxidant, 2-3 parts of rat and ant repellent, 2-4 parts of compatilizer and 2-4 parts of lubricant. Through the coordination of the substances, the cable of the invention has good halogen-free flame retardancy, rat and ant resistance and mechanical performance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a rodent-proof, termite-proof, low-smoke, halogen-free, flame-retardant control cable for ships. Background technique [0002] The power cable is used to transmit and distribute high-power electric energy in the main line of the power system, and the control cable directly transmits the electric energy from the power distribution point of the power system to the power connection line of various electrical equipment and appliances. The rated voltage of the control cable is mainly 450 / 750V. [0003] Control cables have the characteristics of moisture-proof, anti-corrosion and damage-proof, and can be laid in tunnels or cable trenches. They are easily attacked by rodents and ants, causing potential safety hazards. Therefore, it is necessary to increase their performance against rodents and termites. [0004] Polyvinyl chloride is commonly used as insulating material and sheath mater...
