Embodiment 1

[0023] In this embodiment, the sheath material for the data transmission cable is mainly prepared from the following substances by weight:

[0024] Polyvinyl chloride resin (PVC) 100 parts

[0025] Diisononyl phthalate (DINP) 55 parts

[0026] 10 parts epoxy soybean oil

[0027] Calcium zinc composite stabilizer 4 parts

[0028] Carbon black 0.03 parts

[0029] High melting point polyethylene wax 0.5 parts

[0030] Calcium carbonate 50 parts

[0031] First weigh enough materials according to the above weight parts, mix them evenly, and masticate them on a double-roller plasticizing machine with a roll temperature of about 160°C for 5-10 minutes. Cut into a number of sheet samples of 2cm*2cm, press the kneaded sheet with a flat vulcanizer, and then prepare multiple sample bars with a universal sample maker, and then test the thermal stability of the sample bars. The oven method is used for inspection, that is, the sample is placed on a porcelain plate an...

Embodiment 2

[0033] In this embodiment, except for 5 parts of epoxidized soybean oil, the parts by weight of other substances used to prepare the sheath material for data transmission cables are the same as in Example 1, and the same experimental method as in Example 1 is adopted to observe this example The change of spline color below. Experiments show that the color stability of the spline in this embodiment is significantly improved compared with the color stability of the existing polyvinyl chloride cable material, and is better than that of Example 1.

Embodiment 3

[0035] In this embodiment, except for 2 parts of epoxy soybean oil, the parts by weight of other substances used to prepare the sheath material for data transmission cables are the same as in Example 1, and the same experimental method as in Example 1 is adopted to observe this example The change of spline color below. Experiment shows, although the color stability of the spline under this embodiment has improved to a certain extent compared with the color stability of existing polyvinyl chloride cable material, compared with its stability in embodiment 1 and embodiment 2, significantly weakened.

[0036]

[0037] In the above examples, the thermal stability of the sheath material has been improved compared to the thermal stability of the existing polyvinyl chloride cable material, especially the stability of the sheath material prepared in Example 1 and Example 2. The performance has been greatly improved, which is mainly due to the addition of epoxy soybean oil to t...

Abstract

The invention discloses a sheath material for a data transmission cable, which is mainly prepared by, by weight, 100 parts of polyvinyl chloride resin, 40-60 parts of plasticizer, 0<parts<=15 parts of epoxidized soybean oil, 2-10 parts of stabilizing agent, 0<parts<=2 parts of pigment, 0<parts<=2 parts of polyethylene wax and 5-60 parts of calcium carbonate, wherein the plasticizer is diisononyl phthalate, the stabilizing agent is a Ca/Zn composite stabilizer, and the polyethylene wax is high-melting-point polyethylene wax with melting point higher than 105 DEG C. The heat stability of the sheath material for the data transmission cable is improved obviously in the production process compared with the existing polrvinyl chloride sheath materials, and color stability of the sheath material for the data transmission cable is good in the production process. Simultaneously, the production cost is reduced, environmental pollution caused by usage of lead salt stabilizers is further avoided, current environment-friendly requirement is met, and the sheath material has wide application prospect.

Description

[0001] technical field [0002] The invention relates to a sheath material for data transmission cables. [0003] Background technique [0004] With the rapid development of the communication industry, data transmission cables have been widely used, and higher requirements have been put forward for data transmission cables. In addition to requiring good signal transmission performance, the color consistency of cables The standard color difference △L, △a, △b and △E of the standard color difference of the cable sheath are usually required to be less than 3.00, which makes the product unqualified due to improper process control during the cable production process. At present, the cable sheath material is mainly made of polyvinyl chloride plastic. The reason for the color difference of polyvinyl chloride plastic is not only the color matching factor, but also the material decomposition during the manufacturing process will also cause color changes. The manufacturing a...
