Soft cable sheath material for signal transmission of amphibious special vehicle and preparation method thereof

Abstract

The invention discloses a flexible cable sheath material for signal transmission of amphibious special vehicles and a preparation method thereof, which is characterized in that the raw materials for the material include: 600-900 parts of neoprene, 100-300 parts of natural rubber, and nano-zinc oxide 30-60 parts, 20-60 parts of magnesium oxide, 10-30 parts of accelerator, 10-40 parts of anti-aging agent, 200-400 parts of high wear-resistant carbon black, 10-30 parts of stearic acid, 20-60 parts of microcrystalline paraffin 80-150 parts of pottery clay, 20-40 parts of dioctyl ester, 300-500 parts of nano-calcium carbonate, 100-150 parts of rubber antifungal agent, and 80-130 parts of anti-yellowing finishing agent. It is not easy to turn yellow, enhances the tensile properties of materials, improves the strength of soft wires, and is lead-free and mercury-free, which meets ROHS requirements. It has the advantages of extremely strong wear-resistant mechanical properties and good low-temperature resistance.

Description

technical field [0001] The invention relates to the technical field of a flexible cable sheath for signal transmission of amphibious special vehicles, in particular to a flexible cable sheath material for signal transmission of amphibious special vehicles and a preparation method thereof. Background technique [0002] Rubber sheathed cables are widely used in communication equipment, instruments, and power distribution equipment on vehicles. Due to the influence of environmental factors and working conditions, the cable sheath is required to have tensile properties, hardness, Anti-aging, elasticity, antibacterial, flex aging protection and other requirements. [0003] The amphibious special vehicle is currently a vehicle that can be used in both water and land operations, and occupies an important strategic position in the development of national defense. When this special vehicle is used in water, the cable sheath is required in the signal transmission process. With more s...

[0003] The amphibious special vehicle is currently a vehicle that can be used in both water and land operations, and occupies an important strategic position in the development of national defense. When this special vehicle is used in water, the cable sheath is required in the signal transmission process. With more stable performance, it needs to have strong water resistance, anti-aging, elasticity, antibacterial, flex aging protection and other requirements, in order to ensure stable transmission performance and long service life in long-term harsh environments, and also requires The material of this kind of cable sheath is more environmentally friendly to ensure that it will not pollute the water body; however, the existing rubber sheath is easy to turn yellow due to the alkaline nylon yarn in the formula, which greatly reduces the strength of the nylon yarn. , leading to an increased risk of sheath breakage, thereby affecting the stability of the cable transmission performance, and the existing cable sheath has unsatisfactory antibacterial performance, and is easy to pollute and age. In addition, it also contains certain mercury, lead and other pollutants, causing damage to the use environment. pollution
