Problems solved by technology

[0003] Because PVC (polyvinyl chloride) cables are mixed with a large amount of plasticizers and other additives, their flame resistance is insufficient, and HCl gas that is harmful to the human body will be produced when burned, and HCl will also have a strong corrosion effect on metals.
In addition to producing toxic gases, a large amount of smoke will be produced due to incomplete combustion of some gases, seriously affecting people's lives and property safety

Embodiment 1-4

[0039] An environment-friendly -40°C resistant polyvinyl chloride sheathing material for 5G communication cables, including the components in parts by weight shown in Table 1:

[0040] Table 1

[0041]

[0042]

[0043] Preparation:

[0044] (1) Mix PVC resin, plasticizer I, and plasticizer II in parts by weight in Table 1 at a low speed, then add antimony trioxide, flame retardant synergist, composite stabilizer, calcium carbonate, kaolin, light stabilizer Agent, anti-UV agent, antioxidant, impact modifier, lubricant and anti-copper agent are mixed at high speed to obtain a mixture;

[0045] (2) When the temperature during high-speed mixing reaches 100°C, add nitrile rubber to the mixture, and continue high-speed mixing to obtain a blend;

[0046] (3) Extrude and granulate the blended material obtained in step (2) to obtain an environment-friendly -40°C resistant polyvinyl chloride sheath material for 5G communication cables.

[0047] Preferably, the rotating speed o...

Abstract

The invention belongs to the technical field of sheathing materials for communication cables, and particularly relates to an environmental-friendly -40 DEG C resistant polyvinyl chloride (PVC) sheathing material for a 5G communication cable and a preparation method thereof. The PVC sheathing material is prepared from the components: 100-130 parts of PVC resin, 30-45 parts of nitrile rubber, 45-65parts of a plasticizer I, 10-20 parts of a plasticizer II, 5-15 parts of antimony trioxide, 20-30 parts of a flame retardant synergist, 3-7 parts of a composite stabilizer, 20-40 parts of calcium carbonate, 15-30 parts of kaolin, 1-2 parts of an anti-UV agent, 0.5-2 parts of an antioxidant, 1-3 parts of an impact modifier, 0.4-1 part of a lubricant and 0.3-0.6 part of an anti-copper agent. The environmental-friendly -40 DEG C resistant PVC sheathing material is good in flame retardant performance, low in temperature performance and good in UV resistance performance and mechanical performance.

Description

technical field [0001] The invention belongs to the technical field of sheathing materials for communication cables, and in particular relates to an environment-friendly -40°C resistant polyvinyl chloride sheathing material for 5G communication cables and a preparation method thereof. Background technique [0002] The arrival of 5G networks has had a major impact on these critical components, especially the connectors and cables used in wireless and wired infrastructure. Recently, the United States and the United Kingdom announced the accelerated development of 5G networks, which has injected vitality into the entire network industry. Western economies are now trying to compete with China's intensive rollout of 5G technology, but making the leap at scale will depend on adopting new cable technology. [0003] Because PVC (polyvinyl chloride) cables are mixed with a large amount of plasticizers and other additives, their flame resistance is insufficient, and HCl gas that is h...
