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 novel opto-electronic combined medium-voltage trailing cable for port machinery and a manufacturing process thereof. An opto-electronic unit of the trailing cable comprises a loose tube and a tensile insulating layer, wherein the loose tube is internally filled with a plurality of optical fibers, and the tensile insulating layer comprises the following components of CPE Chlorinated polyethylene, an epichloro-hydrin rubber, magnesium oxide, N,N-bi(beta- ethoxyl)-benzimidazolone, dibasic lead sulfate, lead sulfate tribasic, bis(4-octylphenyl)amine, N-N- phenyl p-phenylenediamine, 2,2,4-trimethyl-1, N,N-dimethylaniline, trioctyl trimellitate, an epoxidized soybean oil, a 70# chlorinated paraffin, high wear-resistant carbon black, antimonous oxide, hydrotalcite, ammonium polyphosphate, a precipitated white carbon and an modified roasted nano clay. A tensile strength of the trailing cable provided by the present invention is larger than 12 Mpa, elongation at break of the cable is larger than 350%, aging characteristics and wear-resisting properties of a protecting bush are improved, and an aging temperature can reach 135 DEG C.

Description

technical field [0001] The invention relates to the technical field of photoelectric composite medium-voltage towing cables, in particular to a novel photoelectric composite medium-voltage towing cable for port machinery and a preparation process 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 alo...
