Problems solved by technology

Polyvinyl chloride is a commonly used sheath material. Because the impact resistance of polyvinyl chloride is not very good, the impact resistance of the existing control cables is not good. In addition, the existing control cables have the disadvantage of poor flame retardancy. The sheath is easily destroyed quickly, causing the control system to fail, and the toxic gas released by burning will cause safety hazards to people, thus limiting the application of existing control cables

Abstract

The invention discloses an impact-resistant flame-retardant control cable, comprising an insulating cable core, a shielding layer, an inner sheath, an armor layer and an outer sheath. The outer sheath is made of a modified polyvinyl chloride composite material. A raw material of the modified polyvinyl chloride composite material comprises: polyvinyl chloride, chlorinated polyethylene, styrene-butadiene block copolymer, 2,2,3,3,4,4,4-heptafluorobutyl acrylate, modified montmorillonite, expanded vermiculite, expansible graphite, polypropylene fiber, nano zinc hydroxystannate, a heat stabilizer, stearic acid, lanthanum stearate, epoxidized soybean oil, bis[2-(2-butoxyethoxy)ethyl]adipate, triphenyl phosphate, trioctyl trimellitate, hexaphenoxy cyclotriphosphazene, a modified carbon nano tube and an antioxygen. The impact-resistant flame-retardant control cable of the invention is good in flame resistance, excellent in impact-resistant performance and long in service lifetime.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an impact-resistant and flame-retardant control cable. Background technique [0002] Control cables are mainly used in industrial and mining enterprises, energy and transportation departments, and protection lines. With the rapid development of the control cable industry, the number of control cables continues to increase, and the overall technical level of the industry is greatly improving. Polyvinyl chloride is a commonly used sheath material. Because the impact resistance of polyvinyl chloride is not very good, the impact resistance of the existing control cables is not good. In addition, the existing control cables have the disadvantage of poor flame retardancy. The sheath is easy to be destroyed quickly, causing the control system to fail, and the toxic gas released by burning will cause safety hazards to people, thus limiting the application of the existing control cables. ...
