A kind of flexible wear-resistant cross embedded rubber cable and preparation method

Abstract

The invention discloses a flexible wear-resistant cross embedded rubber cable. The flexible wear-resistant cross embedded rubber cable comprises a cable core and rubber wrapping the cable core. The rubber is of a composite structure and is formed by mutually crossing, embedding and combining soft rubber and wear-resistant flexible rubber; the flexible rubber is prepared from the following raw materials in parts by weight: 50-60 parts of natural rubber, 40-50 parts of butadiene styrene rubber, 40-55 parts of VN3 white carbon black, 8-15 parts of softening oil, 4-6 parts of accelerants, 8-10 parts of processing addition agents and 1-2 parts of stabilizers; the wear-resistant flexible rubber is prepared from the following raw materials in parts by weight: 4-6 parts of CPE (chlorinated polyethylene), 40-55 parts of resin powder, 35-40 parts of calcium powder, 12-15 parts of nano argil, 16-20 parts of DOS (dioctyl sebacate), 10-16 parts of chlorinated paraffin, 0.3-0.5 part of stearic acid,0.4-0.6 part of PE wax, 4-6 parts of carbon black and 0.3-0.8 part of a stabilizer. According to the invention, the cable is good in insulativity, high in flexibility and high in abrasion resistanceand corrosion resistance through the two kinds of rubber materials which are embedded into each other.

Description

technical field [0001] The invention relates to the field of rubber-sheathed flexible cables, in particular to a flexible wear-resistant cross-embedded rubber cable and a preparation method. Background technique [0002] Cables are used in a wide range of fields, including electric power industry, data communication industry, urban rail transit industry, automobile industry, shipbuilding and other industries. The cable is a combination of cable core and rubber sleeve, which has the characteristics of strong rigidity and insufficient flexibility. At the same time, it is long The large temperature difference between day and night tends to accelerate aging. In the prior art, there have been researches on flexible cables, which are mainly realized through the composition process of the rubber material itself. The flexibility is improved while the corrosion resistance is slightly insufficient. In addition, there are external cables. There are multiple layers of material, and the ...

[0002] Cables are used in a wide range of fields, including electric power industry, data communication industry, urban rail transit industry, automobile industry, shipbuilding and other industries. The cable is a combination of cable core and rubber sleeve, which has the characteristics of strong rigidity and insufficient flexibility. At the same time, it is long The large temperature difference between day and night tends to accelerate aging. In the prior art, there have been researches on flexible cables, which are mainly realized through the composition process of the rubber material itself. The flexibility is improved while the corrosion resistance is slightly insufficient. In addition, there are external cables. There are multiple layers of material, and different layers of materials wrap the cable core separately. However, due to the different performance between the layers, the overall consistency and flexibility are still slightly insufficient.
