Abstract

The invention discloses a polyvinyl chloride (PVC) material for a high-speed data cable. The polyvinyl chloride material is characterized by comprising the following components in parts by weight: 100 parts of PVC resin, 32 parts of trioctyl trimellitate, 5 parts of a calcium zinc stabilizer, 8 parts of antimony sesquioxide, 0.4 part of a lubricant, 0.2 part of an antioxidant and 10 parts of a water-resistant modifier, wherein the water-resistant modifier is formed by coating 2 parts of nano barium sulfate, 5.7 parts of calcined kaolin and 2 parts of nano silicon dioxide with 0.3 part of a silane coupling agent; and the lubricant is selected from one or more of stearic acid, barium stearate, calcium stearate, paraffin and polyethylene wax. According to the PVC material, the data cable can be used in a water-soaked environment for a long term; the mechanical stability is good, the electrical performance is stable, and the water ageing resistance performance and the water tree forming resistance performance are achieved in a wet environment, so that the stability of the data cable is further improved and the service cycle of the data cable is further prolonged.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride materials used for high-speed data cables, more specifically, the invention relates to a sheath material used for high-speed data cables. Background technique [0002] PVC cable materials are mainly used as sheath materials for various cables such as power cables, control cables, and communication cables. Polyvinyl chloride cable materials can basically meet the requirements of insulation and sheathing, but with the continuous expansion of the application range of wire and cable, the performance requirements for PVC cable materials are also getting higher and higher, especially the polyvinyl chloride cable materials in the prior art. The water resistance and flame retardancy of vinyl cable materials need to be further improved. [0003] Due to the influence of the natural environment of the sun and rain, outdoor wires and cables have higher requirements on the physical and chemical ind...
