Problems solved by technology

However, the existing hybrid cable sheath materials have weak aging resistance, tear resistance, and compression resistance. If the above functions are to be enhanced, multiple protections need to be deployed, resulting in an increase in cable diameter and cable weight. The hybrid cable sheathing material with good tearing and compression resistance and no need to lay multiple protections needs to be solved urgently

Abstract

The invention discloses a sheathing compound for an optical power composite cable. The sheathing compound contain the following raw materials in parts by weight: 30-50 parts of an acrylic complex, 10-18 parts of polystyrene, 10-20 parts of polyvinyl chloride, 3-9 parts of nylon 66, 0.5-1.2 parts of 2,5-dimethyl-2,5-di(benzoyl peroxide) hexane, 0.1-0.8 part of an accelerant M, 0.5-1.2 parts of triethylene tetramine, 0.4-1 part of succinimide, 1-3 parts of stearic acid, 0.8-1.6 parts of disproportionated rosin, 55-65 parts of a filling reinforcing agent and 2.5-4.5 parts of an anti-aging agent. According to the sheathing compound disclosed by the invention, excellent heat-resistant and waterproof effects can be achieved on the premise of not increasing weight of cables; and moreover, the internal structure of the cable is compact, and the conditions such as wear and broken skin are not caused in the dragging and rolling processes.

Description

technical field [0001] The invention relates to the technical field of cable sheathing, in particular to a sheathing material for a photoelectric hybrid cable. Background technique [0002] Optical hybrid cables are cables in which optical cables and cables are twisted together. It adds an insulated conductor to the optical cable structure, integrating optical fiber and power transmission copper wire. Since optical transmission and electric power transmission belong to two different types of transmission methods, there will be no mutual interference during the transmission process, and at the same time, it can solve the problems of equipment power consumption and signal transmission. It retains the characteristics of ordinary optical fiber cables and can meet low-voltage Relevant standards for power transmission cables. However, the existing hybrid cable sheath materials have weak aging resistance, tear resistance, and compression resistance. If the above functions are to ...
