Problems solved by technology

During the service life of the cable, the sheath must protect the cable core from moisture and other pollution. The degree of protection should keep the circuit performance in the cable core normal. Once too much moisture or other pollutants enter the cable core, the transmission performance will be affected. will seriously deteriorate
This requires the cable sheath to have high mechanical strength and internal toughness to prevent cracking or damage in harsh environments, resulting in abnormal cable transmission or potential safety hazards
[0003] The use of wires and cables in daily life requires good flexibility. The existing wires and cables for daily use can generally maintain a certain degree of flexibility, but they are prone to stress cracking and hardening when used and applied at lower temperatures , Low temperature embrittlement and other phenomena often lead to different degrees of failures, which affect people's normal production and life to a certain extent

Abstract

The invention discloses a soft and low-temperature resisting cable sheath material. The soft and low-temperature resisting cable sheath material is prepared from, by weight, 40-60 parts of polyvinyl chloride, 15-30 parts of polychloroprene, 8-15 parts of ethylene-chlorotrifluoroethylene copolymer, 3-8 parts of polyether polyol, 4-10 parts of a surfactant, 15-30 parts of a plasticizer, 10-20 parts of a nanometer additive and 3-5 parts of white oil. The invention discloses a preparing method of the soft and low-temperature resisting cable sheath material at the same time. According to the soft and low-temperature resisting cable sheath material, a scientific and reasonable formula is obtained through multiple times of experiments and trials, and thus the prepared sheath material has good flexibility, good low-temperature resistance and good flexibility under the low-temperature freezing condition. The sheath material also has the good physical and mechanical properties, good electric insulation performance, good fire resistance, good anti-ageing performance and good abrasion resistance, and the low-temperature resistance of electric wires and cables is greatly improved compared with that of existing plastic sheath cables.

Description

technical field [0001] The invention relates to the technical field of cable processing materials, in particular to a modified muscovite-reinforced chlorosulfonated polyethylene sheath material for external use of cables and a preparation method thereof. Background technique [0002] Wire and cable are the carriers of power transmission and information transmission, and are widely used in industrial and civil electrical facilities. Wires and cables are used in different environments or occasions and have different requirements, which puts forward higher requirements for the cable sheath covering the outside of the cable. The main function of the cable sheath is to mechanically and electrically protect the transmission cable from various conditions that will cause it to lose its transmission function. The cable jacket must fulfill this protective function during installation, splicing and throughout the service life of the cable. During the service life of the cable, the sh...
