Problems solved by technology

With the increase of chlorine content, the compatibility of plasticizer, low temperature resistance, compression set resistance, thermal aging performance, etc. decrease, and the water resistance is poor. When the temperature is relatively low, the material itself is relatively hard, low in elasticity and brittle. Large, low tear resistance
Since the cable sheath material used in coal mines requires that it has the characteristics of softness and good elasticity under any circumstances, chlorinated polyethylene is not suitable for coal mine cable sheath materials due to its own structure.

Abstract

The present invention discloses a high-strength towing-used photoelectric composite cable and a manufacture method thereof. The high-strength towing-used photoelectric composite cable comprises a photoelectric unit, ground wire core conductors and power wire core conductors; wherein the photoelectric unit comprises a loose tube and a tensile insulating layer; and the tensile insulating layer comprises the following parts by weight of components: chlorinated polyethylene, epichlorohydrin rubber, magnesium oxide, zinc oxide, N, N-bis(beta-hydroxyethyl)-benzimidazolone, dibasic lead sulphate, tribasic lead sulphate, 4, 4'-dioctyldiphenylamine, N-N-phenyl-p-phenylenediamine, 2, 2, 4-trimethyl-1, N, N-dimethylaniline, tricapryl trimellitate, epoxidized soybean oil, 70# chlorinated paraffin, high wear-resistant carbon black, antimony oxide, hydrotalcite, ammonium polyphosphate, precipitated white carbon, modified calcined nano clay, gamma-mercaptopropyl triethoxysilane, trimethylol-propane trimethacrylate, triallyl isocyanurate and triallyl cyanurate calcium. The high-strength towing-used photoelectric composite cable of the present invention has tensile strength greater than 12Mpa and elongation at break greater than 350%, aging performance and wear-resistant performance of a sheath can be improved, the aging temperature can achieve 135 DEG C, thus good weather resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of photoelectric composite medium-voltage towing cables, in particular to a photoelectric composite cable for high-strength towing and a manufacturing method thereof. Background technique [0002] Photoelectric composite medium voltage trailing cables for port machinery are suitable for applications with high mechanical stress, mainly used in shore-to-shore container cranes, rail-mounted container gantry cranes, ship unloaders, stacker-reclaimers and other heavy handling equipment. At present, the main material used as the cable sheath is chloroprene rubber. Neoprene rubber has good flame retardancy and good mechanical properties at room temperature, but when the temperature is low, the mechanical properties become poor and the cold resistance is not good. Hardening, loss of adhesion, poor fluidity, poor bonding performance, and the price of neoprene is relatively high. If it is used alone as the main materi...
