Abstract

The invention relates to an efficient fireproof flame-retardant long-service-life cable. The cable sequentially comprises an outermost sheath, a shielding layer, a flame-retardant layer, an innermostprotective layer and a conductor cable core from outside to inside, the outermost sheath is a mixture of polyvinyl chloride and an insect repellent, the shielding layer is a compound of organosiloxaneresin and AZO nanoparticles, and the innermost protective layer is a compound of polystyrene and silicon dioxide nanoparticles. By optimizing the composition of the flame-retardant layer and the outermost sheath, the fireproof and flame-retardant effect and the insect prevention effect of the cable are greatly improved. And the prepared cable meets the requirement of high flame retardancy and issuitable for various extreme environments.

Description

technical field [0001] The invention relates to a cable, in particular to a high-efficiency fireproof, flame-retardant and long-life cable. Background technique [0002] The most basic performance of the cable is that it can effectively transmit electromagnetic waves, light waves, etc., and has certain adaptability to the use environment. In order to make the cable suitable for different occasions, it must have various performances, which can be summarized as follows: the conductor in the cable should have good electrical conductivity, the optical fiber should conduct light waves well without too much loss; and the cladding material should be made of It is required to have good electrical insulation properties, such as insulation resistance, dielectric constant, dielectric loss, breakdown voltage, etc. The transmission performance, anti-interference performance, and signal attenuation of the cable depend on the characteristics of the material and the design and processing o...
