The ultraviolet resistance agent added in the outer insulating layer 5 is one or more of salicylates, benzophenones, benzotriazoles, substituted acrylonitriles, triazines and hindered amines, wherein the ultraviolet resistance agent added in the outer insulating layer 5 in the extrusion process can be specifically 2- (2 '-hydroxy-3', 5 '-di-tertiary phenyl) -5-chlorinated benzotriazole, the ultraviolet resistance agent added in the inner layer can be specifically 2-hydroxy-4-methoxybenzophenone, and the 2- (2' -hydroxy-3 ',5' -di-tertiary phenyl) -5-chlorinated benzotriazole has excellent ultraviolet absorption performance with the wavelength of 270-380nm, good chemical stability and extremely low volatility; the 2-hydroxy-4-methoxyl benzophenone can strongly absorb ultraviolet rays with the wavelength of 240-340nm, has good synergistic effect with other ultraviolet resistant agents, and can be used as a light stabilizer for various coatings. In the extrusion process of the outer insulating layer 5, the ultraviolet resistance agent is added in such a way that the absorption wavelength of the outer layer is longer and the absorption wavelength of the inner layer is shorter; the inner insulating layer 4 is also added with 2,2' -thiobis (4-tert-octylphenol oxy) nickel with an absorption peak of 290nm, and the shorter the wavelength is, the stronger the penetrating power is, so that the main component of the ultraviolet resistance agent is arranged on the absorption wavelength layering level, and the protection effect on the cable is stronger.
By careful design of the layout, the cable has good high-low temperature resistance, wear resistance and elasticity, and the service life of the cable is prolonged. Particularly in the field, the anti-aging agent has good anti-aging effect and torsion performance, and has better use value compared with similar type cables.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
