Abstract

The invention discloses a colorful anti-ultraviolet polyethylene cable outer sheath material. The material is prepared from 25 to 42 parts by weight of high density polyethylene, 12 to 22 parts by weight of linear low density polyethylene, 2 to 5 parts by weight of colorful master batches, 1 to 3 parts by weight of a lubricant, 0.2 to 0.5 part by weight of an antioxidant, 1 to 3 parts by weight of an ultraviolet absorber, 8 to 12 parts by weight of basalt fibers, 3 to 8 parts by weight of glass fibers, 2 to 4 parts by weight of bifenthrin, 6 to 12 parts by weight of toluene, and 5 to 8 parts by weight of capsaicin. The colorful anti-ultraviolet polyethylene cable outer sheath material has excellent anti-ultraviolet and anti-aging performances and excellent mechanical properties, can prevent fading of the cable for a long time, can prevent rat and termite eating and can prolong an optical cable service life.

Description

technical field [0001] The invention belongs to the field of optical cables, in particular to a cable outer sheath material. Background technique [0002] With the modernization of the optical communication industry and the power transmission industry, the transmission of optical and electrical signals and the transmission of control signals require multiple cables to be laid together. For the convenience of engineering installation and maintenance, the cables need to be distinguished into different colors and can be maintained for a long time. Non-fading, thus giving rise to the market demand for colored anti-ultraviolet (UV) polyethylene cable compounds. However, those skilled in the art know that color masterbatches need to be added to colored cable materials, and non-polar polyethylene resins are very difficult to be compatible with polar color toners, and the color dispersibility is poor, and the color of the cable materials made is unstable. It is easy to fade, becaus...
