Embodiment 1

[0025] A cable formula with lightning protection, anti-interference, and low noise. The formula includes the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin, 7 parts of calcium / zinc composite stabilizer, 50 parts of plasticizer, 4 parts of filler , 1 part of lubricant, 0.5 part of bisphenol A antioxidant, 3 parts of carbon black coloring agent, 5 parts of antistatic agent and 2 parts of wave absorbing agent.

[0026] Furthermore, the polyvinyl chloride resin is set as a suspension-method loose type polyvinyl chloride resin, which has a high molecular weight and is easy to absorb a plasticizer.

[0027] Further, the plasticizer is set as a mixture of trioctyl trimellitate, diundecyl phthalate and ditridecyl phthalate, and The mass ratio of monoester and ditridecyl phthalate is set to 2:1:1, and it is better to use multiple plasticizers mixed together than a single plasticizer.

[0028] Further, the filler is set to be a mixture of calcium carbonate a...

Abstract

The invention discloses a cable formula with anti-thunder, anti-interference and low-noise functions and a preparation method. The cable formula comprises the following raw materials in parts by weight: 90-110 parts of polyvinyl chloride resin, 6-8 parts of a calcium / zinc composite stabilizer, 50-60 parts of a plasticizer, 3-5 parts of a filler, 1-2 parts of a lubricant, 0.5-1 part of a bisphenolA antioxidant, 1-3 parts of a carbon black colorant, 3-5 parts of an antistatic agent and 2-3 parts of a wave absorber. By adding the antistatic agent and the wave absorbing agent and reasonably changing the ratio of the components, the cable has the functions of lightning protection, interference resistance, low noise and the like, and the prepared cable can be used outdoors.

Description

Technical field [0001] The invention relates to the technical field of cables, in particular to a cable formula with lightning protection, anti-interference, and low noise functions and a preparation method. Background technique [0002] With the development of science and technology, more and more cables are used, so people have higher and higher requirements for cables. The traditional thermoplastic resins for wires and cables mainly include polyethylene, polyvinyl chloride, polypropylene, fluororesin, and chlorine. Polyether and polyamide, etc., of which PE and PVC are more widely used. However, when the existing cables are used in rain or outdoors, their lightning protection and anti-interference ability are poor, which affects the signal output, and the cable noise is relatively high. Therefore, it is necessary to improve the existing technology to solve the above-mentioned problems. Summary of the invention [0003] (1) Technical problems solved [0004] The purpose of the p...
