Abstract

The invention discloses a colorful ultraviolet resistant polyethylene electric cable material, which is prepared from high-density polyethylene HE6062, linear low-density polyethylene 7042, an ultraviolet absorber, a colorful colorant and an antioxidant through steps of mixing, compounding-extruding, cooling, grain-cutting, drying and the like. The colorful colorant provided by the invention is pre-treated by using a special method, so that the material has very good compatibility and dispersing property with a polyethylene base material; and the prepared electric cable material has excellent ultraviolet resistance, anti-aging property and good mechanical property. With the adoption of the colorful ultraviolet resistant polyethylene electric cable material provided by the invention, an electric cable can be kept fadeless for a long period; the aging and chapping of a cable protection layer is slowed to the greatest extent, so that the colorful ultraviolet resistant polyethylene electric cable material is widely applied to photoelectric cable jackets used in an outdoor filed (including a field with non-natural illumination), such as urban and rural communication networks, urban metros, vehicles and ships, and the like, and also can be used for controlling the insulation of the cable. Particularly, the colorful ultraviolet resistant polyethylene electric cable material is suitable for fields that purposes need to be distinguished by colors of the cable in a signal grading transmission and maintenance process or a cable maintaining process.

Description

technical field [0001] The invention relates to a polyethylene cable material, in particular to a colored anti-ultraviolet (UV) polyethylene cable 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 birth to the market demand for colored anti-ultraviolet (UV) polyethylene cable compound. 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 unsta...
