Problems solved by technology

In order to increase the service life of the cable and ensure the normal operation of the wire and cable, a protective sheath is usually provided outside the cable to protect the cable. The commonly used cable sheath is rubber or polyethylene material, and the elasticity of the rubber sheath is relatively Good, but there are many problems, and the current PVC sheath material has poor flexibility, poor weather resistance, and is easy to age and crack, while the polyethylene sheath material is brittle, poor in wear resistance and tough

Abstract

The invention relates to the field of wires and cables, in particular to a high-strength, waterproof and wear-resistant cable sheath material and a preparation method thereof. The high-strength, waterproof and wear-resistant cable sheath material is prepared from, by weight, 70-100 parts of nitrile silicone rubber, 45-60 parts of styrene-butadiene rubber, 17-30 parts of chlorosulfonated polyethylene, 10-13 parts of butyl epoxy stearate, 10-18 parts of modified muscovite powder, 4-12 parts of zinc stannate, 5-7 parts of expanded perlite, 7-11 parts of vinyltriethoxysilane, 6-15 parts of aluminum hydroxide, 5-8 parts of semi-reinforced carbon black, 5-11 parts of nano-silica, 10-16 parts of filler reinforcer and 6-15 parts of protective agent. The cable sheath material is good in strength, toughness, heat resistance, waterproof property, corrosion resistance and flame retardance, excellent in comprehensive performance, and suitable for many fields.

Description

Technical field [0001] The invention relates to the field of power cables, in particular to a high-strength waterproof and wear-resistant cable sheath material and a preparation method thereof. Background technique [0002] With the gradual acceleration of urbanization, urban planning is becoming more and more modern. In the process of urban construction, cable entry into the ground has become the minimum construction requirement. The same wire and cable are the carriers of power transmission or information transmission, and are widely used in industrial and civil power facilities. The requirements are different for different use environments or occasions. [0003] Wires and cables are widely used in various fields as electrical energy and information transmission bodies. In order to increase the service life of the cable and ensure the normal operation of the wire and cable, a protective sheath is usually set on the outside of the cable to protect the cable. The commonly used c...
