Abstract

The invention discloses a wear-resistant traffic track cable and a preparation method thereof. The preparation method comprises the following steps: 1) carrying out a contact reaction on vinyl chloride, fly ash, lauryl sodium sulfate, nano corundum powder, nano silicon carbide, potassium persulfate, sorbitol, glycerin fatty acid ester and water, and drying and ball-milling to prepare a wear-resistant assistant; 2) mixing polyamide, polycarbonate, polyethylene oxide, paraffin oil, talcum powder, carboxymethyl starch, white carbon black and the wear-resistant assistant to prepare a protective jacket material; and 3) mixing the protective jacket material, coating the material outside the cable core, and cooling and curing to form a protective jacket, thereby obtaining the wear-resistant traffic track cable. The traffic track cable has excellent wear resistance, and the preparation method has the advantages of simple process and readily available raw materials.

Description

technical field [0001] The invention relates to cables, in particular to a wear-resistant traffic track cable and a preparation method thereof. Background technique [0002] The cable is mainly composed of the following four parts. Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be twisted by a single wire or multiple wires; insulation layer: the insulation material used for cables should have high insulation resistance and high breakdown electric field strength, low dielectric loss and low dielectric constant. Sealing sheath: protect the insulated wire core from mechanical damage, moisture, moisture, chemicals, light, etc. For moisture-prone insulation, lead or aluminum extruded sealing sheaths are generally used; protective covering: used to protect the sealing sheath from mechanical damage. [0003] The transportation track cable is a very common ...
