Strong-effect anti-cracking cable sheath and preparing method thereof

Abstract

The invention provides a strong-effect anti-cracking cable sheath and a preparing method thereof, and relates to the technical field of cable production. The cable sheath is prepared from, by weight,55-65 parts of polyethylene, 25-35 parts of epoxy resin, 12-16 parts of carbon fibers, 8-12 parts of quartz fibers, 4-8 parts of polypropylene fibers, 12-16 parts of titanium dioxide, 8-12 parts of polytetrafluoroethylene, 4-8 parts of polyimide, 2-4 parts of an anti-shrinking agent, 1-2 parts of an anti-ageing agent, 2-4 parts of an accelerating agent, 1-2 parts of a dispersing agent and 1-2 parts of a defoaming agent. According to the strong-effect anti-cracking cable sheath and the preparing method thereof, the shortcomings of the prior art are overcome, the low-temperature resistance and anti-cracking performance of the cable sheath are effectively improved, all the components in the cable sheath are jointed mutually, thus the generation and development of cracks of the cable sheath are effectively prevented, then the situation that the cable sheath is frozen and cracks, and electric leakage and other accidents are caused accordingly is prevented, and the strong-effect anti-cracking cable sheath is high in safety, excellent in performance and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of cable sheath production, in particular to a powerful crack-resistant cable sheath and a preparation method thereof. Background technique [0002] The cable jacket is the outermost layer of the cable. The cable is usually composed of three parts, the cable core material, the insulating sheath and the cable sheath, the outer covering of the cable core material is the insulating sheath, and the outer covering of one or more strands of the insulating sheath is covered with the cable sheath. The mutual cooperation between the insulating sheath and the cable sheath plays an important role in protecting the cable core material. [0003] The current formula composition and production process of the cable sheath are unreasonable, resulting in poor crack resistance of the cable sheath. When the outside temperature is low, especially in the twelfth lunar month of winter, the cable sheath is prone to freezing and c...

[0003] The current formula composition and production process of the cable sheath are unreasonable, resulting in poor crack resistance of the cable sheath

When the outside temperature is low, especially in the twelfth lunar month of winter, the cable sheath is prone to freezing and cracking. If the cable sheath is damaged, it is difficult to continue to protect the internal cables, and then accidents such as electric leakage are prone to occur, which is very dangerous. People are causing more trouble
